Power supply circuit of explosion-proof and intrinsically safe mining 5G multifunctional base station access device

Abstract

The invention relates to a power supply circuit of an explosion-proof and intrinsically safe mining 5G multifunctional base station access device, which comprises a wiring terminal strip, the input end of the wiring terminal strip is electrically connected with alternating current, the output end of the wiring terminal strip is electrically connected with a power adapter, the BAT input end of the power adapter is electrically connected with the output end of a lithium manganate lithium ion battery pack, and the BAT input end of the power adapter is electrically connected with the output end of the lithium manganate lithium ion battery pack. The output end of the power adapter is electrically connected with the input end of the 12V DC/DC power module and the input end of the 54V DC/DC power module. The output end of the 12V DC/DC power module and the output end of the 54V DC/DC power module are both electrically connected with the input end of the data output board. In order to improve the stability and fault tolerance of mine communication power supply, the access device circuit is provided with a battery protection circuit, and has the functions of single battery overcharge voltage protection, single battery over-discharge voltage protection, charge overcurrent protection, discharge overcurrent protection, output short circuit protection, temperature protection and the like.

Description

technical field [0001] The invention belongs to the technical field of mine communication equipment, and in particular relates to a power supply circuit of a flameproof and intrinsically safe mine 5G multifunctional base station connector. Background technique [0002] In recent years, with the continuous deepening of mining automation, informatization, and intelligent construction, the data of coal mine automatic control, environmental monitoring, industrial video and other systems have increased significantly. In order to realize the integration of mine communication, wired and wireless integration, the traditional Fixed terminal telephones can no longer meet the current needs, thus restricting the development of smart mines. In order to improve the comprehensive management and control level of coal mines, improve production efficiency, and promote the integration of new generation information technology and traditional equipment in coal mines, 5G technology has greater bro...
