A network video monitoring system for fully mechanized mining face

Abstract

The invention discloses a network video monitoring system for a fully mechanized mining face, belonging to the technical field of monitoring devices, comprising multiple camera modules, multiple communication conversion modules, intrinsically safe switch modules and explosion-proof ring network switch modules, each camera The module is connected to each communication conversion module through a flame-retardant network cable. The adjacent communication conversion modules support three communication methods: optical fiber, network cable and power communication. The appropriate communication method can be selected according to the actual working conditions of the fully mechanized mining face. To achieve a good video transmission effect, the intrinsically safe switch module is connected to one of the communication conversion modules through a flame-retardant network cable, and the flameproof ring network switch module is connected to the intrinsically safe switch through an optical fiber. At the same time, it supports three communication methods: optical fiber, network cable and electric power. The system has a long transmission distance and strong anti-interference ability; thus it can meet the needs of different working surfaces and ensure the smoothness of video.

Description

technical field [0001] The invention relates to a network video monitoring system for a fully mechanized mining face, belonging to the technical field of monitoring devices. Background technique [0002] The video surveillance system refers to the monitoring, control, management and security protection of the monitoring objects through video surveillance. It is a comprehensive management system with strong timeliness. [0003] Due to the harsh working environment, narrow space, complex terrain, and many coal mining and supporting devices, accidents are prone to occur in fully mechanized coal mining face. The video monitoring system is used to realize the real-time monitoring of the safety production of the fully mechanized mining face, timely discover hidden dangers of accidents, and prevent problems before they happen. Therefore, the coal mine video surveillance system has become an indispensable part of mine safety construction. [0004] The development of coal mine vide...

Problems solved by technology

Due to the differences in the size of different working surfaces and working environments, the current video surveillance system cannot support multiple signal transmissions, so it cannot meet the needs of different working surfaces and cannot guarantee the smoothness of the video
