Problems solved by technology

[0003] Since the underground monitoring center is far away from the coal mining roadway of the working face, in the prior art, underground workers need to go back and forth between the monitoring center and the coal mining face many times to confirm the location and type of equipment failure, and the necessary measures to solve the problem. It takes a lot of time and labor costs to maintain tools and equipment spare parts, which brings great trouble to the equipment maintenance work of underground staff.

Abstract

The embodiment of the invention discloses a fault detection method and device of a downhole control system. The method comprises the following steps: obtaining position information of at least one to-be-detected equipment in the downhole control system in real time, and reporting the position information to a monitoring center; controlling shooting equipment to obtain an image and / or video information of to-be-detected the equipment in operating in real time; overlaying fault information of faulty equipment to the image frame of the image and / or video of the faulty equipment if the fact that the to-be-detected equipment breaks down is monitored, and sending the fault information to the monitoring center. According to the method, the fault position and the fault type of the faulty equipment in the downhole control system are determined, and the efficiency for maintaining the downhole faulty equipment is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of control applications, and in particular, to a fault detection method and device for a downhole control system. Background technique [0002] At present, with the continuous improvement of the national coal mine fully mechanized mining automation construction level, the state pays more attention to the safety of coal mine personnel and production equipment, and the coal mine working face hydraulic support, as the most important production auxiliary equipment for the fully mechanized mining face, is the video surveillance of the underground coal mine. The equipment that the system must monitor, but because the hydraulic support often moves up, down and forward in the coal mining production process, and the roof and ground of the coal mining face are mostly uneven, so the support control system equipment will follow the hydraulic support. Up and down and forward movement, so that the cables are o...
