Control Strategy Research For Automatic Scheduling And Control System Of Rubber Tire Vehicle In Coal Mine

There are two modes of transportation, one is the main transportation, and the other is the auxiliary transportation, which is divided into rail auxiliary transportation and non-rail auxiliary transportation. Auxiliary transportation is characterized by suspended single-track rail and the laying double rail ; trackless auxiliary transportation takes motor vehicles as the main feature, in which trackless tire vehicle is one of non-rail auxiliary transportation Currently, many new coal mines adopt this new mode of transportation, but due to the cost and underground coal mining work space, auxiliary transportation roadway is narrow, so it can only accommodate a single vehicle traffic generally, and is prone to lead to not only traffic congestion in a region but also frequent reversing of vehicles, causing many problems,. More seriously, it will cause some safety accidents. To solve these problems, the design of mine tire vehicle automatic control and supervision system is necessary.According to the actual design of coal mine tunnel, the actual building structure of mine is divided into two categories that is linear type of tunnel roadway and divergence. These two structures were studied, based on reading a large number of documents of coal rubber tire vehicle control and supervision system and signal centralized and locking system, the base station layout and control strategy corresponding to the two structures is designed.Mine tire vehicle automatic control and supervision system consists of the surface part and underground part. The ground segment is mainly industrial computer, and the main function is th real-time monitoring, scheduling control, alarm of actual working conditions underground. The underground segment's function is real-time information collection by wireless detection system, the base station passes the vehicle's license plate number, location and driving direction to the PC by bus. Thus, the main task of the host computer is to get the crew information, determine the corresponding control strategy, deliver control commands to the appropriate base station via the bus, and display the real-time image of entire scheduling process in the host computer.The thought of control and strategies have been verified by experiment. The actual experiments shows that the system can meet the real purpose of the automatic control and scheduling, and prove that the design meets the design requirements of the system.
