CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims the benefit of Korean Patent Application No. 10-2011-0091407, filed on Sep. 8, 2011 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. 
       TECHNICAL FIELD 
       [0002]    The present invention relates to a non-contact temperature monitoring device. More particularly, the present invention relates to a non-contact temperature monitoring device that can monitor a temperature state and a field situation of a temperature detection object in real time by enabling to simultaneously output temperature data and image data to a monitoring unit by detecting a temperature of the temperature detection object with a non-contact method while photographing the temperature detection object and that can simplify operation in a normal state by enabling to photograph a state of a temperature detection object through an image photographing unit only when an abnormal situation occurs in a temperature state of the temperature detection object and that can grasp more accurately a field situation through image information in an urgent situation and thus a more quick and accurate action can be performed, thereby previously preventing a fire accident in an industrial field. 
       BACKGROUND ART 
       [0003]    In general, an electric component has a characteristic that emits a heat by electric resistance, and such heat generation damages an electric component and may occur a fire and thus by accurately measuring and grasping a heat generation state of the electric component, it is very important to previously prevent a large accident. 
         [0004]    Particularly, in an industry field, in an electric component that supplies a large amount of electricity, due to heat generation, the frequency of electric component damage and fire occurrence is very high, and in this case, operation of a production facility is stopped or due to a fire, large damage may occur and thus in an industry field, a temperature monitoring device of such an electric component is essential. 
         [0005]    For example, for operation or the control of a power plant and a substation and for operation of a motor, a switchboard in which a switch, a meter, and a relay are installed is installed, and in a large scale factory, various kinds of switchboard boxes such as a Programmable Logic Control (PLC) panel, a high-low pressure panel, a repair panel, an extra-high voltage incoming panel, and a communication system panel are used. In a large scale plant, in a switchboard in which a load greatly applies, in an electric wire or an electrical contact region, due to resistance increase, a high heat occurs and thus in such a switchboard, a temperature monitoring device that can always monitor an inside temperature is installed. 
         [0006]    As such a temperature monitoring device, a temperature detector of a non-contact method is generally used, and a non-contact temperature detector of the conventional art mounts a plurality of infrared ray sensors toward a plurality of specific points to detect a temperature, and the non-contact temperature detector is formed with a method of measuring a temperature of each point through the plurality of infrared ray sensors or a method of installing a thermal image camera that can photograph an entire area temperature of a temperature detection object. 
         [0007]    When using a plurality of infrared ray sensors, an installation work thereof is difficult and a plurality of electric wires should be connected and thus such a non-contact temperature detector has a complicated structure and maintenance thereof is difficult. Further, because a thermal image camera visually provides a relative temperature distribution of a photographing entire area, it is difficult to instantaneously grasp temperature information of a specific point, and due to a structure that cannot detect a temperature by designating only a specific point, a temperature is detected in an entire area including an unnecessary area and thus it is very inefficient in view of efficiency and a cost is expensive and thus there is a problem that the non-contact temperature detector is not widely applied in an industry field. 
         [0008]    Particularly, because a temperature monitoring device of the conventional art simply detects only a temperature, in a state in which a temperature of a temperature detection object is considerably high, a worker cannot know an actual field situation, and only when the worker directly moves to a field, the worker can grasp a field situation and thus the worker cannot directly check fire danger of the field, whereby there is a limitation in taking an appropriate prevention action in a urgent situation.

     BEST MODES FOR CARRYING OUT THE INVENTION 
       [0036]    Exemplary embodiments of the present invention are described with reference to the accompanying drawings in detail. The same reference numbers are used throughout the drawings to refer to the same or like parts. Detailed descriptions of well-known functions and structures incorporated herein may be omitted to avoid obscuring the subject matter of the present invention. 
         [0037]      FIG. 1  is a block diagram illustrating a configuration of a non-contact temperature monitoring device according to an exemplary embodiment of the present invention. 
         [0038]    The non-contact temperature monitoring device according to an exemplary embodiment of the present invention is a device that photographs and monitors a temperature detection object  10  while detecting a temperature of a plurality of points of the temperature detection object  10  with a non-contact method and includes a sensing unit  20 , a data transmitting unit  30 , a monitoring unit  50 , and a controller  40 . 
         [0039]    The sensing unit  20  includes a non-contact temperature detection unit  22  and an image photographing unit  21 , the non-contact temperature detection unit  22  is formed to detect a temperature of a plurality of points of the temperature detection object  10  with a non-contact method, and the image photographing unit  21  is formed to photograph the temperature detection object  10 . In this case, as shown in  FIG. 1 , the non-contact temperature detection unit  22  is formed to detect a temperature of specific points P 1 , P 2 , and P 3  in a range within a photographing area R photographed by the image photographing unit  21 . 
         [0040]    The image photographing unit  21  may be formed in a form including a camera  21   a  that photographs an image, and the non-contact temperature detection unit  22  may be formed to detect a plurality of temperatures of a specific point corresponding to a photographing image of such an image photographing unit  21  and a detailed description thereof will be described later. 
         [0041]    The data transmitting unit  30  is formed to transmit temperature data and image data obtained through the non-contact temperature detection unit  22  and the image photographing unit  21  of the sensing unit  20  to the controller  40 . Such a data transmitting unit  30  is connected to the sensing unit  20  and the controller  40  with a wireless or wired method to transmit data. 
         [0042]    The controller  40  receives temperature data and image data from the data transmitting unit  30  to apply the temperature data and the image data to a monitoring unit  50 , and the monitoring unit  50  receives such data to output the data in real time. 
         [0043]    The monitoring unit  50  includes a display unit  51  that displays temperature data and image data received from the controller  40  and a warning device  53  that can warn a state of temperature data received from the controller  40  and further includes a storage unit  52  that can store temperature data and image data received from the controller  40 . 
         [0044]    The display unit  51  may be formed with a liquid crystal display device so as to display temperature data and image data, and the storage unit  52  is a device that can store temperature data and image data in real time and may be formed with a separate memory device. Such a display unit  51  and storage unit  52  may be embodied with one computer main body and monitor device. The warning device  53  may be formed with a device that can send a warning signal to a user through a hearing and visual signal such as an alarm bell or a light bar. In this case, if temperature data obtained by the non-contact temperature detection unit  22  is equal to or larger than a preset reference value, the controller  40  controls the warning device  53  to operate. 
         [0045]    The non-contact temperature monitoring device according to an exemplary embodiment of the present invention may be formed so that the image photographing unit  21  of the sensing unit  20  may selectively operate only in a specific mode, and for this purpose, in order to select an operation state of the image photographing unit  21 , a separate manipulating unit  60  manipulated by a user may be provided. The manipulating unit  60  may be formed to turn on/off an operation state of the image photographing unit  21 , and the controller  40  is formed to control an operation state of the image photographing unit  21  according to a manipulating signal of such a manipulating unit  60 . 
         [0046]    That is, when an operation state of the image photographing unit  21  is manipulated to an on state by the manipulating unit  60 , the controller  40  operates the image photographing unit  21 , and thus image data is generated to be applied to the monitoring unit  50  through the controller  40 . However, if an operation state of the image photographing unit  21  is manipulated to an off state by the manipulating unit  60 , the controller  40  stops operation of the image photographing unit  21 , and thus generation of image data is stopped and thus only temperature data by the non-contact temperature detection unit  22  is applied to the monitoring unit  50 . 
         [0047]    In other words, the image photographing unit  21  is formed to operate by a user&#39;s manipulation through the manipulating unit  60 , and only during a period in which the image photographing unit  21  operates, image data is generated and applied to the monitoring unit  50 . Therefore, in this case, both temperature data and image data are output through the monitoring unit  50 . However, during a period in which the image photographing unit  21  does not operate, because image data is not generated, only temperature data of the non-contact temperature detection unit  22  is applied to the monitoring unit  50 . Therefore, in this case, only temperature data is output through the monitoring unit  50 . 
         [0048]    The controller  40  controls the image photographing unit  21  to selectively operate by a specific condition in addition to a selective operation by a manipulation of such a manipulating unit  60 , and according to an exemplary embodiment of the present invention, the controller  40  may control to operate according to temperature data obtained by the non-contact temperature detection unit  22 . 
         [0049]    For example, if temperature data obtained by the non-contact temperature detection unit  22  is equal to or larger than a preset reference value, the image photographing unit  21  operates and the controller  40  controls the image photographing unit  21  to photograph the temperature detection object  10 . That is, if a temperature of the temperature detection object  10  detected by the non-contact temperature detection unit  22  is smaller than a reference value, a temperature of the temperature detection object  10  is within a normal range and thus the non-contact temperature detection unit  22  operates with a method of continuing to measure and monitor a temperature of the temperature detection object  10 , and if a temperature of a specific point of the temperature detection object  10  detected by the non-contact temperature detection unit  22  is equal to or larger than a reference value, it represents that an abnormal situation occurs at a corresponding point and thus in this case, the image photographing unit  21  photographs the temperature detection object  10  and outputs a photographing image through the monitoring unit  50 . 
         [0050]      FIG. 2  is a block diagram illustrating a configuration of another form of a non-contact temperature monitoring device according to an exemplary embodiment of the present invention. 
         [0051]    The non-contact temperature monitoring device according to an exemplary embodiment of the present invention may be formed to monitor a plurality of temperature detection objects  10 . For this purpose, as shown in  FIG. 2 , the sensing unit  20  and the data transmitting unit  30  corresponding thereto are each provided in plural, and the controller  40  may control operation of a plurality of sensing units  20  and monitoring units  50 . In this case, the controller  40  may control to alternately output temperature data of a plurality of sensing units  20  to the monitoring unit  50  and thus all of a plurality of temperature detection objects  10  by the plurality of sensing units  20  may be monitored in real time. 
         [0052]    As described above, the manipulating unit  60  manipulated by a user may be formed to select an operation state of the image photographing unit  21  and may be formed to select an operation state of the monitoring unit  50  to a reference mode  61  and a designation mode  62 . In a state of the reference mode  61 , as described above, temperature data of the plurality of sensing units  20  are alternately output to the monitoring unit  50 , and in a state of the designation mode  62 , temperature data of the specific sensing unit  20  in which the user designates are output to the monitoring unit  50 . 
         [0053]    Further, if one temperature data of temperature data of the plurality of sensing units  20  is equal to or larger than a preset reference value, the controller  40  controls the image photographing unit  21  of the corresponding sensing unit  20  to operate and controls to continuously and intensively output temperature data and image data of the corresponding sensing unit  20  to the monitoring unit  50 . 
         [0054]    That is, in any one of a plurality of temperature detection objects  10 , if a temperature rises a reference value or more, temperature data of the sensing unit  20  corresponding to a corresponding temperature detection object  10  rises a reference value or more, and the controller  40  detects this and controls the image photographing unit  21  of the corresponding sensing unit  20  to operate. As the image photographing unit  21  of the corresponding sensing unit  20  operates, temperature data and image data from the corresponding sensing unit  20  are transmitted to the controller  40  through the data transmitting unit  30 , and the controller  40  controls operation of the monitoring unit  50  so that such temperature data and image data continuously and intensively output to the display unit  51  of the monitoring unit  50 . 
         [0055]    Therefore, in a specific temperature detection object  10 , when a temperature rises according to an abnormal situation, temperature data and image data of the corresponding temperature detection object  10  are intensively output to the display unit  51  of the monitoring unit  50 , and thus the user can recognize rapidly and accurately an emergency situation of the corresponding temperature detection object  10 . In this case, the warning device  53  of the monitoring unit  50  will continually operate. 
         [0056]    According to such a configuration, the non-contact temperature monitoring device according to an exemplary embodiment of the present invention may continue to monitor a temperature change state of a plurality of temperature detection objects  10  in real time, and when an abnormal situation in which a temperature increases in the temperature detection object  10  occurs, an image of the corresponding temperature detection object  10  is output in real time and thus an field situation can be more accurately grasped through image information and thus a necessary action can be more rapidly performed. 
         [0057]    Hereinafter, a configuration of a sensing unit of a non-contact temperature monitoring device according to an exemplary embodiment of the present invention will be described in detail with reference to  FIGS. 3 to 8 . 
         [0058]      FIG. 3  is a perspective view illustrating a shape of a sensing unit of a non-contact temperature monitoring device according to an exemplary embodiment of the present invention,  FIG. 4  is an exploded perspective view illustrating a configuration of a sensing unit of a non-contact temperature monitoring device according to an exemplary embodiment of the present invention, and  FIG. 5  is a cross-sectional view illustrating an operation principle of a sensing unit of a non-contact temperature monitoring device according to an exemplary embodiment of the present invention. 
         [0059]    As shown in  FIG. 3 , the sensing unit  20  according to an exemplary embodiment of the present invention is fixed and coupled to be separated from one case  100  so that a relative position of the non-contact temperature detection unit  22  and the image photographing unit  21  is fixed. In this case, one case  100  is coupled to adjust an angle to a separate fixed bracket  101  and is mounted to adjust a temperature detection point of the non-contact temperature detection unit  22  or a photographing area of the image photographing unit  21 . 
         [0060]    In this case, the non-contact temperature detection unit  22  is formed to detect a temperature of a plurality of points P 1 , P 2 , P 3 , and P 4  within a photographing area R photographed by the image photographing unit  21  and thus detects a temperature of a specific point corresponding to an image photographed by the image photographing unit  21 . 
         [0061]    In more detail, as shown in  FIG. 4 , in order to form receiving space therein, the case  100  is divided into a case main body  110  and a case cover  120 , and in the case cover  120 , a plurality of through-holes  121 , 122 , and  123  are formed to protrude and couple the non-contact temperature detection unit  22  and the image photographing unit  21  to the front side. 
         [0062]    The image photographing unit  21  includes a camera  21   a  coupled to the case  100  to photograph the temperature detection object  10  and a lighting lamp  21   b  coupled to the case  100  to radiate lighting light to the front side of the camera, and the controller  40  controls operation of the camera  21   a  and the lighting lamp  21   b , as described above. In this case, it is preferable that as the lighting lamp  21   b , a Light Emitting Diode (LED) lamp is applied. Because general various camera  21   a  and lighting lamp  21   b  may be used, a detailed description of such an image photographing unit  21  will be omitted. 
         [0063]    A non-contact temperature detection unit is a device that can measure a temperature of a plurality of points of a temperature detection object P with a non-contact method and includes a printed circuit board (PCB)  300 , a lens module  500 , an infrared ray sensor chip  400 , and a calculation unit  200 . 
         [0064]    The PCB  300  is fixedly mounted in the main body  110  so as to dispose at inside space of the case  100 , and a light receiving area  310  is formed at one side of a component mounting surface. The light receiving area  310  is a receiving area of infrared rays, having passed through the lens module  500 , and the lens module  500  is coupled to the PCB  300  in a form that receives such a light receiving area  310  therein. 
         [0065]    The lens module  500  collects infrared rays generated in the temperature detection object P and is disposed to protrude the through-hole  121  of the case cover  120  so as to apply light to the light receiving area  310  of the PCB  300 . Such a lens module  500  may be formed with a lens barrel  510  and a lens  520  mounted in the lens barrel  510 , as shown in  FIG. 4 . 
         [0066]    The lens barrel  510  is space that passes through infrared rays applied through the lens  520  and is made of an opaque material so that external light is not injected into the lens barrel  510 . Therefore, the lens barrel  510  may be formed in a hollow cylindrical form or polygonal pillar form, and at the front side surface, in order to insert and couple the lens  520 , the lens barrel  510  is formed in an opened form. Such a lens barrel  510  is mounted in the PCB  300  so that one end thereof encloses the light receiving area  310  of the PCB  300 , and the other end thereof is disposed to protrude to a front side surface of the case  100 , and the lens  520  is coupled to the other end of such a lens barrel  510 . 
         [0067]    In this case, a flange portion  511  is formed at one end of the lens barrel  510 , and a coupling hole  512  for coupling to the PCB  300  is formed to the flange portion  511 . A fixing tab  301  is formed in the PCB  300  to correspond thereto, and such a fixing tab  301  is formed to position at the outside of the light receiving area  310 . Therefore, the lens barrel  510  may be mounted in the PCB  300  with a method of screw coupling a separate coupling screw (not shown) that penetrates the coupling hole  512  to the fixing tab  301 , and in this case, it is preferable to couple to seal without a separation gap so that external light is not applied to internal space of the lens barrel  510  or the light receiving area  310  through a coupling region of the lens barrel  510  and the PCB  300 . In order to intercept such light, a separate interception member (not shown) having an elastic force may be mounted in the flange portion  511  of the lens barrel  510 . 
         [0068]    As the lens  520 , a lens for a general camera may be used, and in order to apply infrared rays in a more wide area to the light receiving area  310 , the lens  520  performs a function of focusing light. Therefore, it is preferable that a convex lens is used for focusing light, and in order to more accurately and variously adjust a path of light arriving in the light receiving area  310 , a plurality of various lens may be further mounted. 
         [0069]    The infrared ray sensor chip  400  is mounted in plural in the light receiving area  310  of the PCB  300  so as to receive infrared rays applied through the lens module  500 . Such an infrared ray sensor chip  400  is an electronic chip that receives infrared rays and converts the infrared rays to an electric signal and is formed to generate a voltage of different magnitudes according to a quantity of received infrared rays. 
         [0070]    The calculation unit  200  is an element that generates a temperature value by receiving and calculating an electric signal of the infrared ray sensor chip  400  and may be connected to the infrared ray sensor chip  400  through a pattern circuit of the PCB  300  in a form of a separate electric chip mounted in the PCB  300 , as shown in  FIG. 4 . 
         [0071]    In such an infrared ray sensor chip  400  and calculation unit  200 , a light electric signal having different voltages in the infrared ray sensor chip  400  is generated according to a light receiving quantity of infrared rays received in the infrared ray sensor chip  400 , and the calculation unit  200  is formed with a method of calculating a corresponding temperature value by correcting and calculating such an electric signal. Such a configuration is a configuration widely used for a general infrared ray sensor for measuring a temperature of a corresponding object using a principle in which infrared rays of different quantities are emitted according to a temperature in an entire object and a detailed description thereof will be omitted. 
         [0072]    The non-contact temperature detection unit  22  according to an exemplary embodiment of the present invention may detect a temperature of a plurality of points of a relatively wide temperature detection target area Q according to such a structure. That is, as shown in  FIG. 1 , in the temperature detection target area Q of an area relatively wider than a size of the lens module  500 , infrared rays are applied to the light receiving area  310  through the lens module  500 , and each of a plurality of infrared ray sensor chips  400  mounted in the light receiving area  310  receives infrared rays, and a temperature of a plurality of points of a corresponding temperature detection target area Q may be detected through such a plurality of infrared ray sensor chips  400 . 
         [0073]    In other words, infrared rays generated in a plurality of points within the temperature detection target area Q are received in a plurality of infrared ray sensor chips  400 , respectively, mounted in the light receiving area  310 , thereby detecting a temperature of each of a plurality of points of the temperature detection target area Q. In this case, the temperature detection target area Q may correspond to a partial area of the temperature detection object P and correspond to an area including an entire area of the temperature detection object P. This may be adjusted according to a separation distance between the non-contact temperature detection unit  22  and the temperature detection object P. Further, it is preferable that such a temperature detection target area Q is limited to a range within a photographing area R of the image photographing unit  21 . 
         [0074]      FIG. 5  is a cross-sectional view illustrating an operation principle of the non-contact temperature detection unit  22 , and hereinafter, an operation principle of the non-contact temperature detection unit  22  according to an exemplary embodiment of the present invention will be described in detail with reference to  FIG. 5 . 
         [0075]    First, in the non-contact temperature detection unit  22  according to an exemplary embodiment of the present invention, infrared rays of the temperature detection target area Q of a relatively wide size like a general camera are focused through the lens module  500  to be applied to the light receiving area  310  of the PCB  300 . In this case, because an incident path of infrared rays changes according to a kind of the lens  520  of the lens module  500 , by changing a kind of the lens  520 , a size of the temperature detection target area Q that can detect may be changed. Further, by changing a separation distance between the non-contact temperature detection unit  22  and the temperature detection object P, a size of the temperature detection target area Q that can detect may be changed. 
         [0076]    In this case, in the light receiving area  310  of the PCB  300 , a plurality of infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d  are mounted, and infrared rays generating at points P 1 , P 2 , P 3 , and P 4  corresponding to the infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d  along an infrared ray incident path are received in the infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d , respectively. Each of the points P 1 , P 2 , P 3 , and P 4  corresponds to some area belonging to the inside of the temperature detection target area Q, and as shown in  FIG. 5 , the temperature detection target area Q is set to correspond to a partial area of the temperature detection object P to detect a temperature, as shown in  FIG. 5 , and it is preferable that the temperature detection target area Q is set to correspond to a partial area within the photographing area R of the image photographing unit  21 . 
         [0077]    In this way, when infrared rays of a plurality of points P 1 , P 2 , P 3 , and P 4  within the temperature detection target area Q are received in each of the infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d , infrared ray emitting amounts are different according to a temperature of each of the points P 1 , P 2 , P 3 , and P 4  and thus electric signals generated in each of the infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d  are differently generated and thus a temperature of a corresponding point is calculated through the calculation unit  200 . 
         [0078]    Therefore, as the non-contact temperature detection unit  22  according to an exemplary embodiment of the present invention disposes a plurality of infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d  within the light receiving area  310 , the non-contact temperature detection unit  22  may detect a temperature of a plurality of points P 1 , P 2 , P 3 , and P 4  of the temperature detection object P, and by variously changing a disposition state of the infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d  within the light receiving area  310 , a position of corresponding plurality of points P 1 , P 2 , P 3 , and P 4  may be variously changed. That is, by changing a disposition state of the infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d , corresponding points P 1 , P 2 , P 3 , and P 4  of the temperature detection target area Q corresponding thereto are changed according to an incident path of infrared rays and thus by changing a disposition state of the infrared ray sensor chips  400   a ,  400   b ,  400   c , and  400   d  according to a kind of the temperature detection object P, a temperature of a specific point of various temperature detection objects P may be detected. 
         [0079]      FIGS. 6 and 7  are diagrams illustrating a temperature detection point setting method of a non-contact temperature detection unit according to an exemplary embodiment of the present invention. 
         [0080]    As shown in  FIG. 5 , as the non-contact temperature detection unit  22  according to an exemplary embodiment of the present invention changes a disposition state of a plurality of infrared ray sensor chips  400  disposed within the light receiving area  310 , a temperature of various specific points of the temperature detection object P may be detected. 
         [0081]    For example, as shown in  FIG. 6 , when wanting to detect a temperatures of six specific points P 1 , P 2 , P 3 , P 4 , P 5 , and P 6  within the temperature detection object P or the temperature detection target area Q, by disposing six infrared ray sensor chips  400   a ,  400   b ,  400   c ,  400   d ,  400   e , and  400   f  at positions corresponding to six specific points P 1 , P 2 , P 3 , P 4 , P 5 , and P 6  along a path in which infrared rays are applied within the light receiving area  310 , a temperature of a corresponding specific point may be detected. As described above, because infrared rays generated in six specific points P 1 , P 2 , P 3 , P 4 , P 5 , and P 6  are received in six infrared ray sensor chips  400   a ,  400   b ,  400   c ,  400   d ,  400   e , and  400   f , respectively, at each point, a temperature can be detected. 
         [0082]    Temperature detection of a specific point of such a temperature detection object P may be performed with a method shown in  FIG. 7 . That is, a plurality of infrared ray sensor chips  400  are evenly disposed in an entire area within the light receiving area  310 , and temperature detection may be performed with a method of activating only specific infrared ray sensor chips  400   a ,  400   b ,  400   c ,  400   d ,  400   e , and  400   f  of the plurality of infrared ray sensor chips  400 . In this case, as described above, the activated specific infrared ray sensor chips  400   a ,  400   b ,  400   c ,  400   d ,  400   e , and  400   f  correspond to an infrared ray sensor chip positioned at a position corresponding to specific points P 1 , P 2 , P 3 , P 4 , P 5 , and P 6  to detect a temperature within the temperature detection object P or the temperature detection target area Q. 
         [0083]    Such an activation method may be performed with a method of mounting a separate switch (not shown) that supplies and intercepts power to each infrared ray sensor chip  400  on the PCB  300  and may be performed with a change of a pattern circuit of the PCB  300  or other various methods. 
         [0084]    In other words, a method shown in  FIG. 6  is a method of detecting a temperature of a plurality of specific points with a method of disposing the infrared ray sensor chip  400  at a corresponding position within the light receiving area  310  with the infrared ray sensor chip  400  corresponding to the number of a specific point to detect a temperature, and a method shown in  FIG. 7  is a method of detecting a temperature of a plurality of specific points with a method of activating only the infrared ray sensor chip  400  of a position corresponding to a specific point to detect a temperature in a state in which the infrared ray sensor chip  400  is disposed in an entire area within the light receiving area  310 . 
         [0085]    Therefore, the user can easily detect a temperature of a plurality of points of the temperature detection object P using an appropriate method according to a field situation or need. 
         [0086]      FIG. 8  is a cross-sectional view illustrating a front and rear moving state of a lens module of a non-contact temperature detection unit according to an exemplary embodiment of the present invention. 
         [0087]    As described above, the lens module  500  according to an exemplary embodiment of the present invention includes the lens barrel  510  that encloses the light receiving area  310  and the lens  520  mounted in the lens barrel  510 , and as shown in  FIG. 4 , the lens barrel  510  may be fixed and coupled to the PCB  300  with a screw coupling method, but alternatively, the lens barrel  510  may be coupled to move in a front-rear direction from the PCB  300 . 
         [0088]    A method of movably coupling the lens barrel  510  may be performed through a fixing device  530  in which a female screw thread  531  is formed at an inner circumferential surface. That is, the fixing device  530  of a ring form is mounted to enclose the light receiving area  310  in the PCB  300 , and at an inner circumferential surface of the fixing device  530 , the female screw thread  531  is formed. In this case, at an outer circumferential surface of one end portion of the lens barrel  510 , in order to screw couple to the female screw thread  531  of the fixing device  530 , a male screw thread  513  is formed, and by screw coupling the lens barrel  510  to the fixing device  530 , the lens barrel  510  may move in the front-rear direction. That is, by rotating the lens barrel  510  clockwise or counterclockwise, the lens barrel  510  moves in the front-rear direction along a screw thread of the fixing device  530 . 
         [0089]    In this way, when the lens barrel  510  moves in the front-rear direction, as shown in  FIG. 8 , a separation distance X between the infrared ray sensor chip  400  mounted in the light receiving area  310  and the lens  520  mounted in the lens barrel  510  changes. When such a separation distance X changes by ΔX, a moving path segment of infrared rays received in the infrared ray sensor chip  400  changes, and thus a position of a temperature detection point in which a temperature is detected by the infrared ray sensor chip  400  is changed. 
         [0090]    Therefore, the non-contact temperature detection unit  22  according to an exemplary embodiment of the present invention can minutely change and correct a position of a corresponding temperature detection point through a position change of such a lens barrel  510 . For example, while using, when a change occurs in a temperature detection point or when a temperature of an accurate point is not detected due to damage of the lens  520 , a position of a corresponding temperature detection point may be corrected through movement of such a lens barrel  510 . 
         [0091]      FIG. 9  is a perspective view illustrating an installation form of a sensing unit according to an exemplary embodiment of the present invention. 
         [0092]    As shown in  FIG. 9 , the non-contact temperature detection unit according to an exemplary embodiment of the present invention is applied to a switchboard P widely used in an industry field for a temperature detection object to detect a temperature of a plurality of points of the switchboard P. 
         [0093]    In the switchboard P, in order to transmit and receive power, a plurality of contact point positions P 1 , P 2 , P 3 , P 4 , P 5 , and P 6  exist, and at such a contact point position, a heat frequently occurs due to increase of electric resistance. Therefore, in order to receive entire infrared rays generated at such contact point positions P 1 , P 2 , P 3 , P 4 , P 5 , and P 6 , the sensing unit  20  may be fixed and mounted through a separate fixed frame  11  at the upper portion side of the switchboard P. 
         [0094]    In the sensing unit  20  mounted in this way, the non-contact temperature detection unit  22  is installed to apply entire infrared rays of a plurality of contact point positions P 1 , P 2 , P 3 , P 4 , P 5 , and P 6  through the lens module  500 , and a temperature of a corresponding position may be detected in real time through the infrared ray sensor chip  400  corresponding to each of contact point positions P 1 , P 2 , P 3 , P 4 , P 5 , and P 6 . Further, the image photographing unit  21  is formed to photograph an area including each of the contact point positions P 1 , P 2 , P 3 , P 4 , P 5 , and P 6 , and when an abnormal situation such as temperature increase at a specific contact point occurs, the image photographing unit  21  is controlled to photograph this. 
         [0095]    In this way, temperature data and image data of each contact point position obtained through the non-contact temperature detection unit  22  and the sensing unit  20  are transmitted to the controller  40  through the data transmitting unit  30  and are applied from the controller  40  to the monitoring unit  50  to be output by the monitoring unit  50 . 
         [0096]    Although exemplary embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that many variations and modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will still fall within the spirit and scope of the present invention, as defined in the appended claims.
