Backup energy-storage power supply managing system of coal mine electronic device

Abstract

The invention relates to a backup energy-storage power supply managing system of a coal mine electronic device, which comprises a municipal power of a rectified power supply for supplying power to all circuits, a backup power supply and the coal mine electronic device, wherein the rectified power supply is connected with a charging module, the charging module is connected with the backup power supply through a connecting port, the backup power supply comprises a battery pack, a microcontroller unit (MCU), a temperature detection module, a current detection module, an intelligent voltage detection module, a balance module, a display module, a charging/discharging switch circuit and an alarming circuit, the charging module is used for charging the battery pack, and the battery voltage detection module detects the voltage of a single-body battery of the battery pack. The backup energy-storage power supply managing system of the coal mine electronic device has the advantages of long service life, good safety performance, directly-viewed displaying of parameters of the battery pack, effective alarming for abnormality and the like. The backup power supply can continue to run under the situation of power failure, so the normal work of the coal mine electronic device can be continued, the running stability of the coal mine electronic device can be greatly improved, and powerful technical support can be provided for the safe and high-efficient production of an entire coal mine.

Description

technical field [0001] The invention relates to a power management system, in particular to a backup energy storage power management system for coal mine electronic equipment. Background technique [0002] The stable operation of mine equipment is of great significance to the safe and efficient production of coal mines. Most of the downhole equipment uses comprehensive protection devices, which can effectively improve the safety and reliability of equipment operation; when equipment fails, it is also convenient for maintenance. If the underground power supply system loses power, the comprehensive protection device will lose the power supply and stop running, which will bring great hidden dangers to the safe production of the coal mine. [0003] The power monitoring system in the coal mine industry is usually greatly affected by the environment. Temperature, humidity, and inclination will all lead to abnormal use of the equipment, which brings great difficulties to ground de...
