Abstract

The invention discloses an intelligent angular displacement sensor. The working environment of mining machines under mines is complicated and inconstant, so accompanied by numerous adverse factors such as high temperature, high humidity, high-strength vibration and the like, mining equipment has the development key point that a high-reliability position detection sensor capable of adapting to severe working environment is developed to realize the detection of operating positions of swing mechanisms of the mining machines. The intelligent angular displacement sensor comprises a shell (5) and a mechanical speed increase amplification mechanism (1), wherein the mechanical speed increase amplification mechanism drives a movable disc (2) embedded with a permanent magnetic sheet; a signal detection fixing disc (3) embedded with a magnetic control reed pipe is fixedly connected with the shell; a vibration damping device (6) is fixedly connected with the shell; and the vibration damping device is fixedly connected with a singlechip signal processing system (4). The intelligent angular displacement sensor is used for detecting the operating positions of the swing mechanisms of the mining machines.

Description

Technical field: [0001] The invention relates to a sensor, in particular to an intelligent angular displacement sensor. Background technique: [0002] At present, the key development directions of mining equipment are: remote control technology for coal mining, remote online real-time monitoring, fault diagnosis and remote control of the operating status of coal shearers; visual remote control technology for cantilever-type tunneling equipment in coal and rock roadways and coal mining in fully mechanized mining faces Equipped with online control and remote control technology. The research and development of remote control technology for coal mining has just started, and the core technology in this area has not been fully mastered, and its sensing technology is one of the core technologies. Considering the working environment of underground mining machinery in coal mines, the conditions are complex and changeable, accompanied by many unfavorable factors such as high temperat...
