BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an infant remote monitoring system, in particular to a system to monitor the heat from the breath of a baby so that to prevent the Sudden Infant Death Syndrome caused by asphyxia. 
         [0003]    2. Description of the Prior Art 
         [0004]    In order to prevent baby from SIDS, some hospitals or families use an asphyxia monitor system to monitor infants&#39; movement. There are so many monitors on the market for that particular purpose. Most of them utilize electronic plates, one of which is Corometrics Infant Monitor model  502 , as shown in  FIG. 4 , which uses two to three electronic plates  5  attached to the underneath or nearby of the nipples of a baby  4 , through the electronic plates  5  to detect the pulse and breath. The electronic plates  5  may irritate the baby&#39;s skin. The electronic plates  5  should be cleaned each time before use in order to acquire accurate readings. The wires, the electronic plates  5  and all contacting points should be checked carefully in order to avoid electric shock. 
         [0005]    Another conventional product is Little Sentry Junior CAN101 of GORMO company, as shown in  FIG. 5 , which is to install all electronic plates SA into a blanket  6  and is secured to the position where the baby&#39;s chest will be to detect the baby&#39;s chest movement when breathing. This design is very fragile and too sensitive, if the baby is too light in weight, the signal may not be accurate. If the baby is too heavy, the electronic plates  5 A may be damaged easily. The system may also detect a false signal with the baby&#39;s movement. 
         [0006]    Another conventional product, as shown in  FIG. 6 , is an air mattress  8 . A sensor  81  is connected with the air mattress  8 . The sensor  81  is then connected to a monitor  7 . With a baby  4  laid on the air mattress  8 , the breath of the baby  4  will cause the air in the air mattress  81  to move up and down, the movement of the air mattress  81  will be detected by the sensor  81 , should the breath stops over the predetermined time, a warning siren will be triggered. The sensitivity and precision depend on the pressure of the air mattress  8 . 
       SUMMARY OF THE INVENTION 
       [0007]    According to the present invention, there is provided with an infant remote monitoring system comprising a sensor unit, a control unit, and a warning device. The sensor unit includes a heat detector and a supporting canopy. The heat detector is displayed in the supporting canopy. The supporting canopy is provided with an adjusting rod and is in an arcuate shape so that when covering a baby, the heat detector will face to the baby&#39;s breathing organ directly. The heat detector of the sensor unit is connected to the control unit which then is connected to the warning device. The warning device comprises a voice warning speaker, a personal computer and a nursing station. By the heat detector, the present invention is to provide a timely warning when the baby&#39;s breath is detected in an abnormal condition to prevent the Sudden Infant Death Syndrome (SIDS).

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0014]    As shown in  FIGS. 1 and 2 , a preferred embodiment of the present invention comprises a sensor unit  1 , a control unit  2 , and a warning device  3 . 
         [0015]    The sensor unit  1  comprises a supporting canopy  11  and a heat detector  12 . The supporting canopy  11  is in an arcuate shape and provided with an adjusting rod  112  to adjust the angle and position of the supporting canopy  11  in relation to the baby. The heat detector  12  is composed of a plurality of heat resistances deployed in the supporting canopy  11 . As shown in  FIG. 3 , the supporting canopy  11  is disposed in an incubator  111 . The heat detector  12  deployed in the supporting canopy  11  faces directly to the baby&#39;s breath organ. The heat detector  12  of the sensor unit  1  is connected to the control unit  2 . The control unit  2  is connected to the warning device  3 . 
         [0016]    The control unit  2  comprises a microprocessor  21 , a front amplifier  22 , a sensitivity adjustor  23  and an analog-digital transformer  24 . The front amplifier  22  amplifies the signal received from the heat detector  12 . The sensitivity adjustor  23  adjusts the sensitivity of the sensor unit  1 . The analog-digital transformer  24  switches the signal type. 
         [0017]    The warning device  3  comprises a voice warning speaker  31 , a personal computer  32  and a nursing station  33 . The personal computer  32  comprises a monitor  321  and a voice warning speaker  322 . The nursing station  33  comprises a monitor  331  and a voice warning speaker  332 . 
         [0018]    When operating the present invention, the supporting canopy  11  is to cover the baby&#39;s head, as shown in  FIG. 3 . In this embodiment, the supporting canopy  11  is placed in the incubator  111 . The supporting canopy  11  is adjusted with the adjusting rod  112  to the most appropriate position so that the heat detector  12  faces directly to the breath organ of a baby  4 . The sensitivity adjustor  23  of the control unit  2  may help the user to adjust the heat detector  12  to the best position as well.
