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.

Mid Motor

The central motor we are referring to here is a central Ebike Motor used on lithium-ion assisted Electric Bicycles, while the common one is the motor used on lithium-ion mountain assisted bicycles. It was developed and put into use after the hub motor, and compared to the hub motor, the technology of the central motor is not yet very mature, so there is still a long way to go in terms of performance stability. But the central motor has a characteristic that hub motors do not have, which is its instantaneous starting assistance function, so it also has a corresponding market. The most common method is to install a center mounted motor on a mountain Electric Bike to meet the bumpy road conditions in the mountains, so both hub motors and center mounted motors have their advantages and disadvantages. The choice of motor depends entirely on which aspect of its functionality you value.Generally speaking, the central motor is used to assist mountain bikes, and hub motors are more common on urban series of assist bicycles.
