Abstract

The invention discloses a video monitoring system for an unmanned work face of a coal mine. The video monitoring system comprises a monitoring front end, a transport network and a monitoring terminal, wherein the monitoring front end comprises at least one video collection device. The video monitoring system is characterized in that the monitoring front end also comprises a bus communicated with the transport network; and the video collection devices are connected in series through an exchange board and then accessed to the bus. The video collection device has the beneficial effects that multiple monitoring point signals are transported by one cable, thereby greatly saving cable quantity and construction time and reducing system cost and construction difficulty; the system is simple in structure and is simple and convenient for maintenance and expansion, new nodes can be arranged without rewiring and can be inserted into a main cable directly; and faults can be found easily, and the system is convenient for maintenance and is simple and reliable.

Description

technical field [0001] The invention relates to a video monitoring system, in particular to a video monitoring system for an unmanned working face of a coal mine. Background technique [0002] Coal mine safety production has always been the top priority in the country's entire safety production system, and the coal mine monitoring system is an important link in the coal mine safety production guarantee system. The coal mine monitoring system is divided into two parts: underground monitoring and above-ground monitoring. It uses the remote video monitoring system, and the staff in the ground dispatching room can directly monitor the underground situation in real time, and can intuitively record and monitor the production and safety conditions of the underground work site. It can also detect hidden dangers of accidents in time, deal with them in time, and obtain first-hand image data for post-event analysis of accidents, providing guarantee for future safe production. Due to t...
