The display control module 22 controls the four-way controllable power supply module 26 and the four-way load electronics module 23. According to the operation of the touch screen 7, the backup battery is charged through the four-way controllable power supply module 26 or the backup battery is charged through the four-way load electronics module 23. Module 23 discharges the backup battery and monitors voltage, current, and temperature during charging and discharging. It stops working and sends an alarm when an abnormality is detected, realizing functions such as over-temperature, over-current, over-voltage, under-voltage, and overload. It records voltage and current values ​​during charging and discharging, calculates the backup battery capacity, and plots the charging and discharging curve. In the event of touch screen 7 failure, this utility model can still be used through the indication of indicator light 8 and the specific operation of button 27, thus keeping the utility model in working condition. In order to maintain the independence and isolation of each channel, the 4-channel controllable power supply module 26 and the 4-channel load electronic module 23 can operate on independent PCB boards to achieve complete isolation.
