Abstract

The invention belongs to the field of underground mine informatization construction and safe production. The invention provides an underground locomotive unmanned driving system which has three modes of a remote driving mode, an unmanned driving mode and a manual driving mode. The underground locomotive unmanned driving system is composed of a monitoring center scheduling command system, a high-precision on-locomotive terminal electric control system, a rail information detecting and control system, a wireless broadband Internet-of-things system, a safe driving determining system and a loading / unloading control system. The scheduling command system transmits an instruction to the on-locomotive terminal electric control system and the rail information detecting and control system through the wireless broadband Internet-of-things. The on-locomotive high-precision navigation terminal of the on-locomotive terminal electric control system controls operation of the locomotive according to the rail condition through a variable-frequency control system. When a fault occurs in individual underground in-production communication or equipment, the underground locomotive unmanned driving system can be temporarily changed to a manual mode, thereby ensuring no production stoppage. The underground locomotive unmanned driving system has advantages of promoting intelligent process of unmanned and large-size equipment in underground production, improving productivity of the mine and realizing considerable safety benefit and economic benefit for mining enterprises.

Description

technical field [0001] The invention belongs to the field of underground mine information construction and safe production, and mainly uses radio positioning technology, wireless communication technology, automatic control and computer technology to realize unmanned driving of electric locomotives in the production and transportation links of underground mines. Background technique [0002] In recent years, the mine safety production monitoring system has developed rapidly. The remote management of underground personnel attendance and positioning, the safety production management information system, and the mine digital gas remote monitoring system have initially realized safety and production remote monitoring. The underground personnel positioning system has been widely used in China, but the positioning technology and equipment of mine mobile equipment have yet to be developed. At present, the positioning accuracy of underground personnel and equipment is not high, and mo...
