Unattended roadheader can be monitored and approved by real-time outside 100 meters

Within a few hundred meters of a simulated roadway, an unmanned boring machine begins to automatically perform various actions of the excavation work. Real-time monitoring of the operation of the roadheader is performed as if it were sitting on the roadheader. This set of China's first national 863 plan key projects for coal machinery and electrical equipment manufacturing, “Tunnelling machine remote control technology and monitoring system”, passed the expert acceptance organized by the Ministry of Science and Technology in Shijiazhuang on August 31st.
The "Remote Control Key Technology for Underground Mining Equipment" jointly undertaken by China University of Mining & Technology (Beijing), China University of Mining & Technology, Suizhong Energy, China Coal Equipment, and Stone Coal Machinery Co., Ltd. was established in February 2008 and completed the prototype in December 2011. Trial production, performance tests and industrial tests, a total of more than 10 million yuan of funds, access to 9 patents for authorization of utility models, published 42 papers, 9 new devices developed by the research and development of "coal mining product safety signs" certificate.
The project will innovate key technologies for the "Trinity and the Seven Systems." Among them, the roadheader remote control technology and monitoring system can realize the visualization and remote control of the orientation, positioning and shaping of the excavation machine during the excavation process from 500m to 1000m. The detection principle and method of the fuselage pose parameter of the roadheader are developed, and the posture parameter detection system is developed. , Multi-parameter directional tunneling feedback control system to achieve high-precision automatic directional excavation; arbitrary section automatic cutting forming control system to achieve precise control of the spatial position of the cutting head; multi-parameter arm cutting speed adaptive control system to achieve different Self-adaptive control of the speed and direction of the cutting arm under working conditions; remote monitoring and remote wireless remote control system for downhole, realizing remote control, remote control and condition monitoring of the roadheader; ground remote monitoring and diagnosis system, realizing downhole digging from 500 to 20000 meters Real-time monitoring and display of machine operating status parameters, and remote fault diagnosis and alarm functions.
Wu Yan, head of the research group and president of the China University of Mining and Technology (Beijing) Institute of Mechanical and Electrical Engineering, said that the remote control technology and monitoring system of the roadheader can be remotely controlled at the near site, and can also be remotely remotely monitored and monitored. It is important for ensuring the safe and efficient mining of coal. Meaning and good social benefits.
