Abstract

The invention discloses a UPS battery fault detection system of an STM32. The UPS battery fault detection system comprises a data acquisition part, a data conversion and transmission part and an upper computer real-time monitoring part, wherein the data acquisition part acquires an internal resistance value of a single battery and a total current value of a group of batteries, the acquired data is subjected to data conversion from a serial port RS485 to a network TCP / IP protocol which is completed by means of the data conversion and transmission part, and the upper computer real-time monitoring part performs real-time display monitoring on the whole system. The UPS battery fault detection system adopts a method of monitoring the internal resistance and current magnitude of the batteries in the case of uninterruptible power, so that the detection and maintenance are more convenient; in addition, the UPS battery fault detection system adopts the method of equipping the group of batteries with a current online monitoring module during the monitoring process, and the power supply ability of the group of batteries can be detected simultaneously. The UPS battery fault detection system adopts the STM32 single chip microcomputer, thus the monitoring cost can be reduced; and the UPS battery fault detection system adopts the serial RS485 for data communication and transmission, the expansibility is better, and the signal transmission is more stable.

Description

technical field [0001] The invention relates to the technical field of online monitoring of UPS batteries, in particular to an STM32 UPS battery fault detection system. Background technique [0002] As banking equipment has higher and higher requirements on the performance and reliability of the power supply, UPS has been widely used. The reliable power supply of the backup battery in the UPS system is very important. The internal resistance of the UPS battery is tested to ensure that the battery has sufficient storage capacity. Energy becomes a key issue. For the current UPS power supply used in the computer room of the bank data management system, the UPS battery has insufficient power storage capacity, the battery is aging, and the power cannot be cut off at any time. Instruments are used to monitor battery failures. [0003] Traditional UPS battery testing has the following disadvantages: the battery pack needs to be separated from the system, which increases the risk o...
