Intelligent remote control technology for fully-mechanized roadheader of Tangkou Coal Mine
Abstract
At present, research and application of automation of fully-mechanized roadheader and intelligence of fully-mechanized process in China have achieved initial results, but there are still some problems in intelligent perception and remote control technologies. In terms of actual conditions of fully-mechanized heading face in Tangkou Coal Mine, automatic location, cutting, remote control technologies of fully-mechanized roadheader are used to develop an intelligent remote control system for fully-mechanized roadheader. Full-automatic explosive proof type total station is adopted to locate the roadheader combining with many sensors. Operation system, electrical control system and hydraulic pressure system of the roadheader are upgraded to realize location data analysis, automatic planning of cutting actions and other functions. Remote control of automatic location and one-key cutting of the roadheader are realized by use of long distance transmission protocol. The application show that after implementation of the intelligent remote control system for fully-mechanized roadheader, unmanned operation in range of 30-50 m away from fully-mechanized heading face in Tangkou Coal Mine is realized, which improvs safety production level, and only one operator is needed in a team to achieve goal of downsizing staffs and improving efficiency.
