Description
Technical Field

Background
Mine electric locomotives are important transportation tools for underground transportation personnel, ores and materials, and are used for bearing important tasks in underground transportation. The coal exploitation scale and yield of China are increased year by year, mining operation roadways are deepened and expanded continuously, and the number of electric locomotives and turnouts is increased. Therefore, a system is needed to allow an electric locomotive to quickly and safely pass through a fork, thereby achieving the purposes of safe, efficient and effective transportation.
At present, when the electric locomotive is driven to the vicinity of a turnout opening, manual switching or remote controller control of turnout change is adopted manually, so that the configuration of underground personnel is increased, and the transportation efficiency of the electric locomotive is reduced. Therefore, a set of safe, reliable and complete intelligent underground electric locomotive control system is established, so that the mine transportation safety is ensured, the command efficiency is improved, the transportation cost is reduced, and the intelligent underground electric locomotive control system has important research significance.
Therefore, the invention provides the cloud-vehicle-rail cooperative intelligent management and control system for the underground electric locomotive, which completes cooperative information interaction sharing among the rails through a wired and wireless heterogeneous fusion integrated communication system, and automatically sends signal instructions of a signal machine and a turnout signal according to a dispatching task so as to achieve the purpose of quickly and safely passing through a turnout of the channel of the electric locomotive. The switch machine is important signal basic equipment for reliably switching the switch position, changing the switch opening direction, locking the switch tongue and reflecting the switch position, and can well ensure the driving safety, improve the transportation efficiency and improve the labor intensity of driving personnel. In the coal mine tunnel track, the switch machine is fixed in a switch machine pit, a switch machine pull rod is required to pass through a steel rail downwards and is connected with the steel rail through a connecting piece, the switch machine case is fixed on basic angle steel, and the basic angle steel is fixed on a stock rail. When a signal inputs a pulling instruction, the pull rod pulls the switch rail and locks the switch rail, so that the switch is realized. Therefore, the bottom of the foundation pit must be lower than the ballast surface, so that water accumulation is easy to occur. The ponding source mainly comprises ballast flushing water, tunnel structure water leakage, fire-fighting wastewater and the like. If accumulated water in the foundation pit of the switch machine can not be discharged in time, the accumulated water can enter the switch machine to influence the normal operation of the switch machine. At present, drainage in a foundation pit of a switch machine is mainly performed by arranging drainage ditches on two sides of a ballast bed, but the drainage effect is not ideal due to sinking of the foundation pit, water flow blockage and the like.
