Detailed ways

As shown in Figure 1, the current detection circuit detects the current value passing through the power line in real time and sends it to the microcontroller; the temperature sensor detects the temperature value of the power line in real time and sends it to the microcontroller; after the microcontroller receives the current value passing through the power line and the temperature value of the power line, it will first receive the The current value and temperature value are compared with the current setting threshold and temperature setting threshold stored in the memory respectively. When any measured data is greater than the corresponding setting threshold, the single-chip microcomputer controls the cooling fan to start working, and the power distribution box The power line and other equipment are cooled to ensure the safety of power supply. At the same time, the single-chip microcomputer controls the sound and light alarm to alarm through sound and light effects. The single-chip microcomputer also sends the alarm information to the mobile phone of the relevant staff in the form of a short message through the GPRS communication module superior. Described alarm information comprises the serial number of sound and light alarm, the position and the mobile phone number of relevant staff etc., and these alarm information can all be stored in the memory that is connected with described single-chip microcomputer, and described single-chip microcomputer can directly read from described single-chip microcomputer when needed. extracted from memory.
