Fig. 1 is a schematic structural diagram of a backup power state determination system according to an embodiment of the present invention, and as shown in fig. 1, the backup power state determination system 10 includes a control center 101 and at least one backup power 102. The control center 101 and any backup power supply 102 perform data interaction through a MODBUS communication protocol, and the control center is used for acquiring the current state of any backup power supply 102 according to the MODBUS communication protocol, and the backup power supply 102 is used for sending the current state of the backup power supply to the control center 101. MODBUS is a serial communication protocol, and this embodiment utilizes the master-slave communication characteristics of MODBUS, and the master station circularly requests data from the slave station, and the slave station responds to the corresponding data after receiving the instruction from the master station.
In this embodiment, control center 101 is the MODBUS master station, and backup power source 102 is the MODBUS slave station, and control center 101 and backup power source 102 pass through RS485 communication port and connect. For example, the MODBUS master device is a computer with a standard MODBUS driver, and is connected to the backup power source 102 through an RS485 communication port, an RS232 or USB port. The number relationship between the master and slave stations may be one-to-one or one-to-many, i.e. the control center 101 may simultaneously obtain the current status of multiple backup power sources 102.

The control center 101 sends a state acquisition request to the backup power source 102 through a MODBUS communication protocol, and after receiving the request of the control center 101, the backup power source 102 sends the current state of the backup power source 102 to the control center 101, so that the control center 101 can acquire the current state of the backup power source 102, and the working state of the backup power source 102 can be displayed in real time.
In this embodiment, optionally, the control center includes an address sending module and a state receiving module; the address sending module is connected with the backup power supply through an MODBUS communication protocol and used for sending a target address to any backup power supply; wherein the target address comprises a target register address; and the state receiving module is connected with the backup power supply through an MODBUS communication protocol and used for acquiring the current state of the target address of the backup power supply.

The destination address may include a destination device address and a destination register address, and the control center 101 may obtain current states of the plurality of backup power sources 102, where each backup power source 102 corresponds to its own device address. When acquiring the current state of the backup power sources 102, the control center 101 may first determine a target backup power source in the backup power sources 102, and send a device address of the target backup power source as a target device address to any backup power source 102, thereby acquiring the current state of the target backup power source. An address receiving module 1021, a status transmitting module 1022, and a device determining module 1023 may be included in the backup power source 102. The address sending module 1011 sends the target address to the address receiving module 1021, and after the address receiving module 1021 receives the target address, the target address may be sent to the device determining module 1023. The device determination module 1023 obtains the target device address from the target addresses and determines the target backup power. For example, the device determination module 1023 may determine whether the target device address matches the self device address of the self backup power supply, according to the acquired target device address and the self device address of the self backup power supply. If yes, it is determined that the backup power source where the backup power source is located is the target backup power source, and the target register address is sent to the state sending module 1022 of the target backup power source, that is, sent to the state sending module 1022 of the backup power source.
