the power supply detection method of the power distribution cabinet comprises the following specific steps of initial data writing, mobile detection, data comparison and cooling system:
initial data are written in, and data such as normal working temperature of 0-60 ℃ when the electric wire works and highest temperature of 75 ℃ born by the electric wire when works are written in the digital memory manually, and the highest allowable temperature of 130 ℃ in short time are written in the digital memory, so that initial values are provided for detection;
after the initial data is written, the digital memory sends out a signal to the controller, the controller sends out the signal to control the Y transmission mechanism and the X transmission mechanism to move the detection bracket, so that the detection bracket moves in the distribution box in an arch shape, and the circuit at the rear side of the electrical installation frame is detected;
in the process of moving detection, the thermal infrared imager synchronously transmits the detected line segment to the display screen, synchronously writes the detected data signals into the digital memory and transmits the digital memory to the controller, and performs data comparison between the data received by the controller and the initial data, so that the controller performs corresponding control operation on the subsequent detection through a data comparison result;
and the temperature reducing system is used for starting the temperature reducing system by the controller if the temperature of a certain section of line is detected to be too high in the moving detection process, and the controller starts the temperature reducing system and covers the overheat line by the heat conducting gasket at the front end of the temperature reducing mechanism so as to physically cool the line by the heat transfer effect of the heat conducting gasket.

Optionally, the data comparison includes normal temperature and abnormal temperature, and the specific steps are as follows:
after the data of the movement detection is written into the digital memory, the digital memory judges whether the written data is in a normal working temperature range or not by comparing the initial data, and when the data is compared in the normal working temperature range, the digital memory feeds back a signal to the controller, and the controller continues to carry out the movement detection program;
the method comprises the steps that when the temperature is abnormal, data of movement detection are written into a digital memory, data signals are synchronously sent to a controller, the controller compares initial data, when the temperature exceeds 130 ℃, a thermal infrared imager monitors that the line time is not longer than 30s, movement detection is continued if the temperature at any time point in 30s is reduced, if the temperature is still higher than 130 ℃, a cooling system is started, a line is clamped through a heat conducting gasket, movement detection of the next line is continued if the temperature is reduced, if the temperature is still not reduced, a feedback signal is sent to the controller, the controller starts an alarm lamp, if the working temperature of a certain line is higher than 75 ℃ but lower than 130 ℃, the cooling system is started, physical cooling is performed on the certain line through the heat conducting gasket, movement detection program is continued if the temperature is reduced to the normal working temperature, if the temperature is higher than 75 ℃ for a long time, the controller generates an alarm signal, and the controller starts the alarm lamp to alarm.
By adopting the technical scheme, when the temperature is abnormal, the temperature is fed back to the controller according to different numerical ranges received by the digital memory, so that the controller can make corresponding control actions according to different temperature changes, wherein the digital memory is formed by connecting an independent control unit with a data memory, the independent control unit is communicated with the controller and receives data stored by the controller, the independent control unit compares the stored data with a threshold value and feeds back the comparison result to the controller, and the temperature reaches 130 ℃ in a circuit without causing excessive burden on the circuit, so that a cooling system is not directly started when the temperature reaches 130 ℃, but is continuously monitored for a period of time, and when the temperature is lower than 130 ℃ than 75 ℃, the temperature is not detailed due to the reason that the temperature is increased, the cooling action is firstly adopted, and then the next control action is carried out through the change of the temperature.
Compared with the prior art, the invention has the beneficial effects that:
the system digitizes the detection heat of the circuit through the thermal infrared imager, transmits the numerical value signal to the digital memory, synchronously transmits the data signal to the controller, compares the data by the controller, and completes the power supply detection process of the distribution box through different processing steps by the controller according to different comparison results;
the system can carry out emergency cooling treatment on the section of line when the temperature of the line is too high by arranging the cooling mechanism, so that the conditions of ageing of the line, fire and the like caused by continuous high temperature of the line are avoided;
the upper limit column and the lower limit column are adopted at the box door of the system to limit the opening size of the box door, so that the conditions of circuit breakage, electric device damage and the like caused by overlarge opening angle of the box door are prevented, and meanwhile, the system is simple in structure and convenient to install;
according to the detection method, the temperature of the circuit is digitized, and meanwhile, the thermal infrared imager can be used for targeted locking of the area where the circuit has problems, so that convenience is brought to overhaul and maintenance of operators, and a large amount of time cost is saved.
