The central controller 1 is also connected with a temperature sensor.

Described central controller 1 is also connected with LED display and keyboard.

The working process of the utility model is as follows: the same as the basic function of the UPS power supply on the market, the utility model is also provided with two working modes: one is in the normal state of the mains power supply, through the voltage stabilization set inside the control device The device 3 rectifies and stabilizes the input voltage, so that the output voltage is continuous and stable. At the same time, the voltage sensor 4 collects the regulated voltage data, the current sensor 7 collects the battery pack 6 charging data, and the temperature sensor collects The collected temperature data of the central controller 1 is uniformly transmitted to the central controller 1, and the central controller 1 temporarily stores the processed data in the data storage module through data processing, and at the same time transmits the processed data to the communication module 9 The communication module 9 can upload the collected data to the monitoring center computer 10 through the RS485 communication cable or the CAN industrial serial port transmission bus, and the staff can check the collected data in the monitoring room, whether the monitoring control device is running normally; The communication module 9 is improved to increase the function of wireless transmission, so that the staff can view the monitoring data anytime and anywhere through the handheld wireless monitoring device 11 in a certain area, and issue corresponding action instructions, such as switching the charging and discharging mode of operation.

Another situation is: when the mains power is cut off, the control device can quickly switch to the battery power supply state, the whole switching process has no delay and can make the voltage transition of the power supply side smooth. The input end provides stable direct current, and during the battery power supply process, the above-mentioned voltage sensor 4, current sensor 7 and temperature sensor continue to collect working data under the power supply state of the battery pack, and transmit it to the corresponding terminal.

Considering the complexity of the UPS power supply environment, when the UPS power supply is placed in an environment with signal or magnetic field interference, the central controller 1 may fail, causing the power control switch 8 to fail to operate accurately, and the power supply circuit of the battery pack 6 is under load. After disappearing, it is not actually cut off, and the battery pack 6 is still consuming power. At this time, such problems can be solved by setting the relay normally closed switch; when the voltage of the voltage sensor 4 on the power output side of the central controller 1 drops to a certain threshold, the central The controller 1 will disconnect the power supply control switch 8 from the battery circuit. Even in the event of an action failure, the power supply control switch 8 cannot be disconnected after being closed.
