Problems solved by technology

At present, most of these power sources are powered by lead-acid batteries. Lead-acid batteries have large weight and volume, short life, and produce harmful gases during work and maintenance.
The rapid growth of lithium-ion batteries provides a new way of energy storage, but its application requires a reliable battery management system and safe and effective charging and discharging measures, so far it has not been used in underground mining environments

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As shown, the present invention is a large-capacity lithium-ion battery power supply system for underground emergency avoidance and lifesaving facilities. The power supply system is divided into a main control device 1 , a charging and discharging device 2 and a power supply device 3 .

[0034] The main control device 1 includes a main control explosion-proof box 4 and a liquid crystal display module 5 connected thereto; wherein, as figure 2 As shown, the main control explosion-proof box is divided into a main control cavity and a wiring cavity. The main control cavity is equipped with a main control board (BMCU: Battery Management Control Unit) 6, power conversion 7, main circuit relay 8 and intrinsically safe power supply module 9 ;The wiring cavity is equipped with external power input terminals, battery input term...

Abstract

The invention relates to a high-capacity lithium ion battery power supply system for a well emergency risk avoiding lifesaving facility. A master control apparatus is connected with a charge and discharge apparatus and a power supply apparatus; the charge and discharge apparatus is connected with the power supply apparatus; the master apparatus receives power supply state signals of the charge and discharge apparatus and the power supply apparatus, controls the charging of the charge and discharge apparatus and the battery management of the power supply apparatus through a CAN bus and, performs voltage conversation on external commercial power for supplying to the risk avoiding lifesaving facility, and is also provided with a liquid crystal display function; the charge and discharge apparatus performs logic control of charge and discharge according to the control command of the master control apparatus; and the power supply apparatus performs power supply management according to the control instruction of the master control apparatus and is used for finishing uninterrupted power supply to the risk avoiding lifesaving facility in case of abnormal external power supply. The advantages are as follows: the structural design is flexible, a master-slave type control mode is employed, a subordination control panel and a battery pack are arranged in a power supply explosion-proof case, information data exchange is finished through the CAN bus and a master control board, and management and expansion of multiple power supply modules are realized flexibly.

Description

technical field [0001] The invention belongs to the field of underground emergency escape and lifesaving systems in coal mines, in particular to a large-capacity power supply system that provides power for underground emergency escape and lifesaving facilities. Background technique [0002] Accidents frequently occur in my country's coal mine industry, and the reasons are generally backward equipment and facilities, outdated processes and chaotic management measures. Mine accidents often cause huge losses and casualties. The emergency avoidance and lifesaving system can provide a life-saving space for underground operators to ensure life safety when an accident occurs, and is an important part of the underground rescue system. When an accident occurs, the life-saving facilities may need a large-capacity power supply to provide power when the external power supply is lost, to maintain the normal operation of the entire life-saving facilities and ensure the normal internal wor...
