The system is divided into five modules, namely: UPS monitoring module, battery monitoring module, power distribution cabinet monitoring module, air conditioning monitoring module and environmental monitoring module. Each module can run independently with background software, and can also be combined according to the requirements of the computer room. In the UPS monitoring module, information such as UPS operation status, input voltage, output voltage, temperature and so on can be monitored, and the monitoring host equipment corresponds to UPS one by one.

In the battery monitoring module, the voltage, current and cell voltage of the battery pack can be realized. According to the topology diagram, the monitoring of battery charging and discharging information can be carried out on a single battery, the whole battery can also be detected, and the two can be combined into a battery cabinet for monitoring. In the power distribution cabinet monitoring module, it can be divided into ordinary power distribution cabinet monitoring and intelligent power distribution cabinet monitoring, both of which can monitor the voltage and current data of the power distribution cabinet.
