Substation battery pack online monitoring device based on LTE communication technology

Abstract

The invention provides a substation battery pack online monitoring device based on a LTE communication technology, and relates to the technical field of intelligent battery pack online monitoring. Thedevice comprises a switching power supply, an MCU core module, a UART serial bus, a data acquisition module, an LTE network communication module and a human-machine interaction module, and is used asa core device for data acquisition, processing, calculation, alarm and transmission of a substation battery pack and a battery unit. The device uses a high-precision sensor to collect the operating data of the battery pack and the battery unit, after analyzing and processing the data through the MCU core module, and the data is sent to a remote monitoring center host system through the LTE network module. The device adopts a LTE communication technology to achieve remote data transmission, achieves remote monitoring functions, has high stability, is accurate and reliable, has excellent performance, and is flexible and simple to operate.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of intelligent battery packs, in particular to an on-line monitoring device for battery packs in substations based on LTE communication technology. Background technique [0002] The role of the DC power supply system in power plants and substations is mainly to provide working power for protection, control and other equipment. In order to ensure the reliability of the power supply of the DC system, battery packs are used as the backup power supply. At present, the status monitoring of battery packs in substations usually uses the RS485 bus to realize the communication connection between the battery pack online monitoring unit and the SCADA system. After the monitoring unit is installed in the substation battery pack, it is necessary to focus on how to deploy communication cables. Communication wiring occupies most of the project. workload. In this method of data collection and remote ...

AI Technical Summary

Problems solved by technology

Problems such as cumbersome wiring, aesthetic impact, and time-consuming and energy-consuming problems occurred during the transformation of the existing substation battery packs. In some remote substations (not yet connected to the automation system), it is impossible to transmit data from the monitoring unit to the remote host, resulting in Remote real-time monitoring of substation battery packs cannot be realized
