Fully mechanized working face monitoring system and coal mining machine

Abstract

The invention provides a fully mechanized working face monitoring system which comprises at least one collecting device, a data transmission unit and a display device, wherein the at least one collecting device is installed on a coal mining machine, collects video information and/or audio information of a working face, and transmits the video information and/or the audio information to the data transmission unit; the data transmission unit transmits the video information and/or the audio information to the display device; and the display device processes the video information and/or the audio information respectively and plays processed audio information. According to the technical scheme provided by the invention, the audio information and the video information of the fully mechanized working face can be acquired directly through the collecting device, and can be monitored in real time through the display device, the collected audio information is played through an audio device, and the condition of the working face can be monitored intuitively. The invention also provides a coal mining machine comprising the fully mechanized working face monitoring system.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a video monitoring system for a fully mechanized mining face and a coal shearer. Background technique [0002] The underground working environment is complicated and harsh, with narrow space and complicated terrain, especially in the thin coal seam working environment, which is restricted by the narrow space, which seriously affects production safety and coal mining efficiency, and also increases the labor intensity of workers. At present, there are few simple and practical monitoring methods to place the video monitoring system on the fully mechanized mining face to monitor the status of the working face and the operation status of the shearer in real time. Therefore, it is more important to improve the degree of automation of coal mining. [0003] In the related art, a shearer position receiving system is installed on the hydraulic support of the coal mining system to rece...

Problems solved by technology

This solution is complicated and difficult to implement and requires the cooperation of multiple devices, which will reduce the reliability of the system and increase the number of failure points.

[0005] Secondly, due to the limitation of the communication distance of Ethernet, many nodes need to be added for long-distance communication, which affects the reliability of the system

In addition, it is difficult for the staff in the control room to feel the coal and rock cutting of the coal shearer on the actual working face simply by transmitting video signals.
