Problems solved by technology

Since the current monitoring and management system for battery working status is still blank in our country, it is difficult to guarantee the reliability of the battery power supply system.
At present, the management systems used by domestic enterprises are all from foreign products, which are costly, difficult to manage and upgrade, and are only suitable for low-voltage and small-current devices. The measurement and control system is not perfect and the degree of intelligence is low.

Abstract

The invention relates to a monitoring system and mainly relates to a battery state network monitoring system for a large battery power supply system. The battery state network monitoring system for the large battery power supply system comprises a main monitoring chamber, a branch monitoring chamber and a base station, wherein the base station is composed of a processor, a detection circuit, an output circuit, a communication interface, a failure warning circuit and a charging circuit. The system is of a classified management structure, and a single chip microcomputer serves as a base station of a monitoring unit to achieve battery state data collection and battery input and removal; the system is simple in structure and low in cost and achieves distribution of collected information, data teletransmission and monitoring and control of a large power supply battery. An original breakdown maintenance mechanism is modified into a state maintenance mechanism through the application of the system, the probability of failure is reduced, and the power supply reliability of the battery power supply system is improved.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a battery state network monitoring system for a large-scale battery power supply system. Background technique [0002] With the rising calls for green and environmental protection worldwide, electric vehicles and other green and low-carbon economical electrical equipment are gradually increasing. Because valve-regulated sealed lead-acid batteries have excellent characteristics such as small size, light weight, small self-discharge, long life, convenient use, safety and reliability, etc., they have been widely used in power systems. At present, large-scale battery-powered equipment generally uses batteries as the main battery. source of power supply. Since the current monitoring and management system for the working state of the battery is still blank in our country, it is difficult to guarantee the reliability of the battery power supply system. At present, the management systems used by...
