Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to a remote control method for snow removal and disaster prevention system using smart phone, and more particularly, to a remote control method for snow removal and disaster prevention system using a smart phone, which remotely controls the snow removal system installed at a site while checking conditions of a road and the snow removal system in real time when improvement of a road surface is needed because a condition of the mad surface deteriorates due to dusts, yellow sand, frozen snow on the road surface, etc. that occur in cities. 
         [0003]    2. Description of the Related Art 
         [0004]    Generally, when snow is piled up or frozen on a road surface in a vulnerable place such as a straight road, a bridge, a curved road, an uphill road, an entrance of a tunnel, or the like, the piled-up or frozen snow obstructs a traffic flow, and a road condition deteriorates. Dusts piled up on a road are the same. 
         [0005]    As an example of a method of removing and thawing snow, there is a method that sprays a thawing agent and a snow removing agent such as calcium chloride, or a friction agent such as sand, a grain particle chip, or the like. The method has limitations in that it is almost impossible to uniformly spray a spraying agent on a surface of a multilane road having a broad width, and traffic control and congestion are accompanied. Also, them is a method that mechanically sprays a spraying agent using a spray vehicle, but the method has limitations in traffic control and the use of equipment. 
         [0006]    In snow-removing and thawing work dependent on the use of equipment and manpower, since equipment and manpower should be put to a site, it is substantially impossible to quickly remove snow. For this reason, various methods are studied. 
         [0007]    “Spraying device of removal of snow on the mad” disclosed in Korean Patent Registration No. 225035 and “a cats eye mad marker with spray” disclosed in Korean Patent Registration No. 750937 are representatively known for removing snow. 
         [0008]    These are technologies proposed for previously restoring and quickly measuring a road surface requiring removal of snow, and are technologies proposed for replacing the jet of a spraying agent with mechanical spray. 
         [0009]    “Spraying device of removal of snow on the road” disclosed in Korean Patent Registration NO. 225035, as illustrated in  FIG. 1 , includes an installation chamber  10 , a snow removing agent storage tank  11 , a compressor  12 , and a plurality of jet ports  13  connected to the compressor  12 . In the spraying device, a jet port  13  is installed to have a certain height from a central lane and central reservation of a road  14  or an edge of a road surface, and a snow removing agent is sprayed on the road surface. In such technology, since a spray means is separated from a jet means, integrated management is difficult. As the spraying device is simply a road facility for spraying a spraying agent on a road surface, usability is low. Since the spraying device operates according to direct manipulation, the spraying device is difficult to early respond. The spraying device has a restriction in selecting an installation position, and is impossible to movably install. 
         [0010]    “A cat&#39;s eye road marker with spray” disclosed in Korean Patent Registration No. 750937, as illustrated in  FIG. 2 , includes a body  20  with a reflective plate  21  attached thereto, a supporting pillar  22  that is installed as a whole under the body  20  and supports the body  20 , and a coupling bolt coupled to the supporting pillar  22  through the body  20 . A spray nozzle  23 , connected to a liquid supply source  26  through a connector  24 , is built in an internal space of the body  20  so as to jet liquid. The body  20  is buried under the ground and fixed by a bracket  27 , and jets contents of the liquid supply source  26  to the spray nozzle  23  through a pump  25 . 
         [0011]    In the technology, since the road marker is installed at a central reservation portion, the mad marker is immovable, and there is a high possibility that the nozzle is blocked or damaged. Also, it is impossible to remotely control the time of jetting, and thus, the technology is difficult to early respond. Since a liquid supply means is separated from a jet means, integrated management is difficult, and there are many restrictions in selecting an installation position. 
         [0012]    “Remote controlled scattering apparatus”, disclosed in Korean Patent Registration No. 0985174 filed by the applicant, enables an early response to remove the snow through real-time remote control. 
         [0013]    The related art apparatuses for spraying liquid on a road, which include a remote control function using wired/wireless data communication, are all installed to be neglected on roads, and thus, due to carelessness and negligence in surveillance, it is unable to respond to damage or robbery of expensive application components. 
         [0014]    Moreover, since the liquid spraying apparatus is neglected and put in an operation standby state, more accurate control is needed depending on ambient conditions. For example, it is required to transfer various pieces of information, which is necessary for operating the liquid spraying apparatus, such as road condition information and a current facility management state, to a manager in real time. For example, the information includes climatic and environmental information, affecting an operation of the liquid spraying apparatus, such as a temperature, a humidity, etc. 
         [0015]    In addition, by acquiring and transferring various pieces of information necessary for a remote control operation, an efficient operation can be expected, but, current technology is still in fundamental power control such as simple power control and pump driving by wired/wireless data communication.

The external case  107  configures a lower structure. 
         [0047]    An example applying a solar cell part  200  for replacing commercial electricity is illustrated in  FIGS. 3 to 6 . A solar cell plate  301  is installed outside the body  103  and the external case  107 , for supplying power necessary for a plurality of driving components including the pump  105  and the remote terminal device  200 . 
         [0048]    The body  103  and the external case  107  may be configured as one body, or separately configured.  FIGS. 3 and 4  illustrate an example of an integrated structure. 
         [0049]    The remote terminal device  200  is built in the external case  107 . The remote terminal device  200  includes a data communication unit  201 , and processes external SMS data received through the data communication unit  201  to recognize application SMS data of a smart phone  500  applied for controlling driving of the pump  105  and functional parts, thereby driving the pump  105  and the functional parts. 
         [0050]    The remote terminal device  200  includes a bidirectional data communication unit  201  that receives external application SMS data over the mobile communication network  400  and transmits predetermined information over the mobile communication network  400 , and a control unit  206  that is connected to a display element unit  202 , the pump  105 , a surveillance camera  204 , a detection sensor  205 , and a flow rate measurement sensor  210  to input/output signal data and calculates and inputs/outputs a data signal in connection with a controller  209  installed in one or more of the elements. 
         [0051]    The remote terminal device  200  includes a memory  207  that is connected to the control unit  206  and the data communication unit  201 , and stores data transmitted and calculated between a remote terminal unit and a programmable logic controller of the control unit  206  and a calculation result by a processor. Also, the remote terminal device  200  includes a data input/output unit  208  that inputs/outputs system default data or variable data to/from a plurality of units. 
         [0052]    Here, the control unit  206  includes a central processing unit (CPU) that has an integrated control function for a microprocessor, a main control unit (MCU), and a microcomputer, a programmable logic controller (PLC) that controls the pump  105  according to a programmed command input as SMS data of the smart phone  200  side, and an remote terminal unit (RTU) that collects data output from the pump  105  and performs comparison control. 
         [0053]    The control unit  206  further includes a human machine interface (HMI) that transmits signals, transmitted between the PLC and the RTU, to the smart phone  500  through the data communication unit  201  to visually display an image or text corresponding to the signals, and inputs/outputs data. 
         [0054]    The control unit  206  includes the detection sensor  205  that senses external environmental information, and the flow rate measurement sensor  210  that checks a flow rate of the spraying agent  102  stored in the storage room  101  of the body  103 . The control unit  206  outputs information, detected by the detection sensor  205  and the flow rate measurement sensor  210 , to the data communication unit  201  to enable the data to be transmitted to the smart phone  500 . A processor built in the smart phone  500  programs data of detection information supplied from the control unit  206 , thereby displaying the external environmental information and measurement information, detected by the detection sensor  205  and the flow rate measurement sensor  210 , through the smart phone  500 . 
         [0055]    Here, the external environmental information includes one or more of a contact impact on the body  103  and the external case  107  that are installed on a road, sound, light, an acceleration, a distance, a humidity, and a temperature. 
         [0056]    The data communication unit  201  receives an SMS data signal sent by a manager from the smart phone  500  so as to control the remote snow removal system, and inputs the SMS data signal to the remote terminal device  200  or transmits information, calculated by the remote terminal device  200 , to the manager. 
         [0057]    In a remote control method of the snow removal system according to the present invention, as illustrated in the flowchart of  FIG. 11 , the smart phone  500  controls the snow removal system connectable to the mobile communication network  400  in real time. 
         [0058]    Here, the smart phone  500  includes an application  501  that transmits SMS data to the control unit  206  through the data communication unit  201  of the remote terminal device,  200 , a program operating system (OS)  502  that includes the application  501  and drives the remote terminal device  200 , and a telephoney application interface (TAPI)  503  that receives data transmitted from the remote terminal device  200  by using an inter-process connection (IPC) extracts a teleservice identifier (ID) from the data, checks the application  501  corresponding to the data with the teleservice ID, generates data of the application  501  in a type enabling a service by the checked application  501  with user data included in the SMS data and the teleservice ID, and maps the generated data to the checked application  501 . The smart phone  500  stores transmitted/received information in the memory  504 , and extracts desired information from the memory  504 . 
         [0059]    In the control method of the snow removal system using the smart phone  500 , a user of the smart phone  500  accesses the mobile communication network  400 , and accesses the remote terminal device  200  of the snow removal system installed at a site in real time, in operation S 601 . 
         [0060]    The control unit  206  determines whether the user accessed through operation S 601  is an authorized manager. When it is determined that the accessed user is not the authorized manger, the control unit  206  blocks the access to the smart phone  500 , and allows the access of the authorized manager using the smart phone  500 , in operation S 602 . 
         [0061]    The manager allowed through operation S 602  transmits data using the smart phone  500 , in operation S 603 . 
         [0062]    The CPU of the remote terminal device  200  is driven by the data value transmitted through operation S 603  to output a data value, in operation S 604 . 
         [0063]    In operation S 605 , by driving the pump  105  installed at the site, the spraying agent  102  is sprayed through the nozzle  106 , or, by stopping operation of the pump  105  that is spraying the spraying agent  102 , the spray of the spraying agent  102  is stopped. 
         [0064]    Whether to spray the spraying agent  102  is determined according to whether the pump  105  is driven, in operation S 605 . The control method compares data input/output values stored and set in the CPU and memory of the remote terminal device  200  to transmit detection information to the manager, in operation S 606 . 
         [0065]    The manager checks a data value transmitted through operation S 606  by using contents displayed by the smart phone  500  to determine whether an error occurs, and determines whether to continuously perform a current operation according to the determined result in operation S 607 . 
         [0066]    The manager obtains information collected through operation S 607  to check an overall state of the remote snow removal system by using the smart phone  500 , and selectively transfers a control command to each of the functional units through the controller  209 , in operation S 608 . 
         [0067]    The processed result by operation S 608  is fed back to the manager through the smart phone  500 , and is stored, in operation S 609 . 
         [0068]    Moreover, an example of an SMS data processing operation performed by the remote terminal device  200  is as illustrated in the flowchart of  FIG. 12 . 
         [0069]    SMS data is transmitted from the smart phone  500 , and, when the SMS data is received in operation S 701 , the remote terminal device  200  extracts a teleservice ID of the SMS data in operation S 702 , and checks an application corresponding to the teleservice ID in operation S 703 . When the corresponding application does not match the teleservice ID, the remote terminal device  200  stops a service. When the corresponding application matches the teleservice ID, the remote terminal device  200  allows generation of new application data in operation S 704 , and the smart phone  500  generates the new application data in operation S 705 . The remote terminal device  200  maps the generated application data to an application program of the control unit  206  in operation S 706 . In operations S 707  to S 709 , SMS data based on an application is input to the remote terminal device  200 , and the remote terminal device  200  is driven with the SMS data to control operation of the pump  105 , thereby controlling the spray of the spraying agent  102 . 
         [0070]    Moreover, a control command for each functional unit executed in operation S 608  is tier one or more selected from among the display element unit  202 , the surveillance camera  204 , the detection sensor  205 , the flow rate measurement sensor  210 , and the controller  209  selectively executes the control command for each functional unit. 
         [0071]    Here, the display element unit  202  includes a means (generating warning sound  202   a ) such as a buzzer (speaker), a light lamp  202   b  installed in the system body  103  and the external case  107  to be exposed, a light emitting unit  202   c  that visually shows a driving state like a light emitting diode (LED), etc. The display element unit  202  is selectively installed and operated depending on a site condition. 
         [0072]    The surveillance camera  204  captures a site of the snow removal system installed at the site to store the captured site image, or transmits image data through the remote terminal device  200  so as to monitor the site in real time. The surveillance camera  204  is selectively installed and operated depending on a site condition. 
         [0073]    The control command executed by the controller  209  is executed through the CPU that receives the SMS data of the smart phone  500  and has an integrated control function for the microprocessor or microcomputer included in the control unit  206  of the remote terminal device  200 , the PLC that controls the pump  105  according to a programmed command input as SMS data of the smart phone  500  side, and the RTU that collects data output from the pump  105  and performs comparison control. 
         [0074]    The flow rate measurement sensor  210  is installed in the storage room  101  of the body  103 , and detects a flow rate to output the detected flow rate to the control unit  206 . The control unit  206  compares and calculates the output value of the flow rate measurement sensor  210  to check whether the spraying agent  102  is lost and robbed and an operation is normally performed based on a change amount of the flow rate by using the smart phone  500 . 
         [0075]    The display element unit  202  may include a warning sound unit  202   a  using a buzzer, the light lamp  202   b , and the display unit  202   c.    
         [0076]    When an impact or a contact similar thereto is applied on the body  103  or the external case  107 , or a level of the spraying agent  102  is rapidly reduced abnormally, the detection sensor  205  or the flow rate measurement sensor  210  detects the impact or the reduced spraying agent, and the warning sound unit  202   a  outputs warning sound through a speaker or buzzer (not shown). 
         [0077]    The light lamp  202   h  emits light while the spraying agent  102  is sprayed. Alternatively, when an impact or a contact similar thereto is applied on the body  103  or the external case  107 , or a rapid reduction in a level of the spraying agent  102  stored in the storage room  101  is detected by the detection sensor  205  and the flow rate measurement sensor  210 , the light lamp  202   b  emits light for externally warning the impact/contact or the rapid reduction. Here, a time when the light lamp  202   b  emits light may be freely set according to a program set in the control unit  206  of the remote terminal device  200 . 
         [0078]    The display unit  202   c , although not specifically shown in the drawing, may use an LED. The LED is more suitable for displaying various driving states than a general lamp. A driving signal of the display unit  202   c  may be variously controlled by the display/pump/image/sensor controller  209  of the control unit  206 . 
         [0079]    The remote terminal device  200  receives an SMS data signal, transmitted from the smart phone  500  through the mobile communication network  400 , through the data communication unit  201  in real time. The control unit  206  of the remote terminal device  200  outputs the SMS data signal as a data signal value, and thus the CPU controls the pump  105 , the display element unit  202 , the surveillance camera  204 , the detection sensor  205 , the flow rate measurement sensor  210 , thereby storing and controlling data. 
         [0080]    It is suitable to use a wireless communication network, for example, a communication network provided by a commercial mobile communication provider, instead of a wired communication network, as the mobile communication network  400   
         [0081]    In a processing type of a data signal, remote control is executed by transmitting short sentence text SMS data. The short sentence text SMS data using a smart phone has no limitation in a buffer, an error, and an amount of input/output information compared to different data, and thus is suitable as high-reliability data. 
         [0082]    Power necessary for driving the snow removal system, for example, may use alternating current (AC). A power source may use a commercial power source or a solar energy system that converts solar energy, including electromagnetic radiation with a wavelength within a sola band, into electrical energy. 
         [0083]    The remote control of the snow removal system using the smart phone according to the present invention is performed with the smart phone  500 . In addition, a wireless communication service using a wireless communication network based on computer, electronic, and communication technology may be used. 
         [0084]    A service provided in a mobile communication system includes a voice service, and a multimedia communication service transmitting data such as circuit data or packet data. 
         [0085]    The smart phone includes a large-capacity memory and a high-performance CPU compared to the existing mobile communication terminals, and moreover includes an OS for supporting execution of various applications, voice/data communication, and a personal computer (PC) connection. For example, the OS may representatively use Symbian, WindowsCE, or Linux. 
         [0086]    Korea adopted wireless Internet platform for interoperability (WIPI) as wireless Internet platform standard for portable phones, and mobile communication providers and terminal manufacturers install (port) the WIPI between an OS (for example REX or the like) layer and application layer of a mobile communication terminal. 
         [0087]    As described above, the existing mobile communication terminals are released with the WIPI being installed in the existing OS such as REX. However, since the WIPI is not installed in smart phones that are recently released, mobile communication providers and terminal manufacturers are developing technology that installs the WIPI in smart phones such that applications (for example, browser, wireless Internet menu, contents, bell sound, video, word processing program, etc.) executed based on the WIPI are smoothly executed in the smart phones. 
         [0088]      FIG. 10  is a block diagram illustrating a data link between the remote terminal device  200  and the system elements of the smart phone  500  that is a type of mobile communication terminal. 
         [0089]    The smart phone  500  includes a native application  501 , a WIPI application  501 , the OS  502 , the TAPI  503 , and the memory  504 . 
         [0090]    The native application  501  corresponds to various applications (website browsing, contents download, and multimedia message (S)MMS writing, etc.) that are driven by the native platform in the smart phone  500 . 
         [0091]    The WIPI application  502  corresponds to various applications (website browsing, contents download, and multimedia message MMS writing, etc.) that are driven by the native platform in the smart phone  500 . 
         [0092]    The OS  502  is a control means that controls an overall operation of the smart phone  500 . 
         [0093]    The TAPI  503  receives data transmitted from the remote terminal device  200  by using an inter-process connection (IPC), extracts a teleservice identifier (ID) from the data checks the application  501  corresponding to the data with the teleservice ID, generates data of the application  501  in a type enabling a service by the checked application  501  with user data included in the SMS data and the teleservice ID, and maps the generated data to the checked application  501 . 
         [0094]    The memory  504  is a storage means that stores various data necessary for driving the smart phone  500 . 
         [0095]    In the smart phone  500 , various applications, for example, various kinds of the WIPI applications  501  executed based on the WIPI and the native application  501  executed based on a structure of a window mobile platform, are installed on the OS (i.e., Symbian, WindowsCE, or Linux)  502 . Each of the applications is read from, written in, or deleted from a specific area of the memory  504  to which various data necessary for executing the smart phone  500  are allocated from the OS  502 . 
         [0096]    The OS  502  of the smart, phone  500  treats the WIPI as an application, and thus teats the WIPI applications  501  executed based on the WIPI or the native application  501  executed based on a structure of a window mobile platform as one application, whereby a plurality of applications are set to executed as a multi-application. 
         [0097]    Like this, since the multi-application is executed in the smart phone  500 , a user may simultaneously perform various works (website browsing, contents download, and multimedia message (S)MMS writing, etc.) with one or more applications in driving the remote snow removal system. 
         [0098]    A message sent to the data communication unit  201  of the remote terminal device  200  installed at the site may use SMS data having a basic short sentence type. 
         [0099]    To link data intimation between the applications, the smart phone  500  may transfer desired data information through a command line that transfers data when an application is executed. 
         [0100]    In a scheme of linking data information between the same types of applications, the data information is linked between applications in the same types of platforms. When an application is driven, data of a small number of texts, for example, about 256 words, is easily processed. Accordingly, text data having a short sentence type is transmitted to the remote terminal device  200  with the application of the smart phone  500 , and thus, information processing for inputting and outputting data is quickly executed at a high speed. 
         [0101]    In a command line scheme, the native application  501  may transfer data information with an execution parameter at a time when another native application is executed. A scheme that links the data information through the command line may transfer only text data of up to a maximum of 256 words. 
         [0102]    The scheme using the command line has a limit in a data information capacity, and, due to different platform (window mobile platform vs WIPI platform) structures of different types of applications (i.e., native application and WIPI application), it is unable to link the applications through the command line. 
         [0103]    This can affect reception of large-scale information such as image information captured by the surveillance camera  204  connected to the remote terminal device  200 . Such a limitation can be overcome by improving the specifications and performance of the applications and platforms of the smart phone  500 , and it is stable to control driving of the pump  105  by transmitting a text type of SMS data of a short sentence. 
         [0104]    According to the present invention, snow-removing work is previously decided through an operation of determining a road surface condition, and if the manger transmits information on the decided snow-removing work as SMS data by using the smart phone  500  in a scheme of transmitting a specific data code value, the SMS data is transmitted through the data communication unit  201  of the remote terminal device  200 . The control unit  206  recognizes the SMS data to determine whether to drive the pump  105  according to a predetermined algorithm, stop driving of the pump  105 , transfer a new signal to each function through the controller  209 , or obtain information, and compares and outputs input values to perform control. 
         [0105]    The remote snow removal system of the present invention may be remotely controlled in real time by the smart phone  500  depending on a road condition determined by the manager, and automatically driven in the order of condition setting and arbitrary time setting-driving state check-automatic data transmission-pump driving by the control unit  206  configuring the remote terminal device  200 . 
         [0106]    The related art apparatuses for spraying liquid on a road, which include a remote control function, are all installed to be neglected on roads, and thus, due to carelessness and negligence in surveillance, it is unable to respond to damage or robbery of expensive application components. 
         [0107]    According to the present invention, detection, measurement, diagnosis, and warning are performed with the surveillance camera  204 , the detection sensor  205 , the flow rate measurement sensor  210 , the warning sound unit  202   a , the light lamp  202   b , and the display unit  202   c , and various pieces of information is received and obtained by the smart phone  500  able to process large-scale data, thus effectively preventing damage and robbery. 
         [0108]    For example, contact impact information is detected by the detection sensor  205 . When a physical impact is applied on the body  103  or the external case  107 , the control unit  206  detects a state change and stores the detected information or sends the detected information to the smart phone (manager terminal)  500 , and, by outputting warning sound through the warning sound unit  202   a  or flickering the light lamp  202   b , the control unit  206  causes the state change to be visually output. 
         [0109]    Likewise, since various pieces of site information, such as sound, intensity of illumination, speed, distance, etc., is obtained through the detection sensor  205 , a condition of the snow removal system is clearly checked based on the obtained information, and a change in a flow rate of the spraying agent  102  is detected through the flow rate measurement sensor  210 . Accordingly, it is possible to monitor and check whether supplement is necessary through various routes in consideration of a driven time. 
         [0110]    Moreover, information of a road condition and a current facility management state am detected by the detection sensor  205 , and various pieces of information necessary for driving the snow removal system is transferred to the manger in real time. For example, climatic and environmental information (such as a temperature and a humidity) affecting driving of the snow removal system, a contact impact applied on a structure, a residual amount of the spraying agent, and a loss state of the spraying agent are detected, and are transmitted as data to the manager. 
         [0111]    The manager technically controls the snow removal system by collecting various pieces of information necessary for driving of the snow removal system, and the snow removal system is controlled by inputting simple SMS data to the smart phone  500  and transmitting the SMS data. Accordingly, system control is quickly, conveniently performed. 
         [0112]    It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents. 
         [0113]    The present invention enables the continuous management of a snow removal system installed on a road to be remotely performed, and transfers various pieces of information, which is necessary for operating the snow removal system, such as a road condition and a current facility management state, to a manager in real time, thus enabling the remote control of the snow removal system to be efficiently, accurately performed.
