FIELD PREVENTING DEVICE USING THERMAL IMAGE AND CONTROL PANEL FIELD OF THE INVENTION [0001]

FIELD OF THE INVENTION The present invention relates to a fire prevention apparatus that can be applied to a control panel or the like to prevent fire by using thermal images, and a control panel having the fire prevention apparatus.

The causes of the recent fires in traditional market fires have been found to be caused by electrical causes such as short circuit, short circuit, overload and overheating. In addition, fire caused by electrical factors is frequently occurring at home as well as at industrial sites.

Recent statistics show that the number of fires caused by ignition sources in 2016 is much higher than that of fire extinguishers, and 8,912 fires are caused by electric fires among 43,000 fires. As described above, electrical factors account for 20% of all fires, so fire prevention and preemptive response to electrical factors are required.

Conventional techniques for fire prevention detect smoke or gas after a fire has occurred and alert them. Such a conventional fire prevention method has a limitation in preventing a complete fire because it gives a warning such as an alarm after a certain degree of fire has occurred. In addition, conventional electric fire prevention techniques such as over current or short circuit interruption have a problem that there is still a possibility of fire because there is a limitation in preventing fire when the power is not overloaded such as deterioration or defective parts.

As a method to prevent fire from occurring, there is a method of predicting or judging the possibility of a fire by taking a thermal image of a fire expected area by using a thermal image measuring device. Thermal imaging equipment can be mobile or stationary. In the portable type, the portable type captures the thermal image of the point where the fire is expected to occur while the user is carrying it, which is insufficient in preventing fire because it can not obtain the continuous and periodic thermal image. In addition, the fixed type is installed at a predicted point of fire occurrence and it is effective for fire prevention as compared with the portable type because it can continuously capture thermal image. However, in the case of a fixed type thermography apparatus, there are technological and economical problems that a large number of photographing apparatuses must be installed to cover a large area.
