Abstract:
In response to the problems of low hoisting efficiency,large safety hidden danger,low degree of accuracy control and others in vertical shafts of Yushujing,by means of self-designed,processed,transformation and installation,an innovative technology system for the double redundancy of the upper and lower metal support structure and the truss type support mechanism structure of the hoist shaft is created.A remote monitoring and unmanned control system for the hoist is developed using "solid-state type physical link encoding and decoding control".For the first time,the new type of KVM technology is applied to the coal mine automation control system,transforming the traditional "software+fiber optic point-to-point transmission control concept" into a "solid-state type physical link encoding and decoding control concept".The mine vehicle operation system design and application innovative technology system and vehicle operation system intelligent voice broadcast control system under wireless remote control are created in the auxiliary shaft,the detection and protection system for preventing vehicle offside in cage hoisting is deeply integrated,solving the difficult problems faced by the technical development of hoist speed up,efficient production,unmanned automation control system,remote control system stability and others in the coal mine vertical shaft hoisting system,and the economic and application effects are significant.
