Mine unmanned vehicle distance safety management and control method and system

Abstract

The invention discloses a mine unmanned train distance safety management and control method and system, and belongs to the technical field of safe operation of trains under a mine. The method comprises the following steps: respectively obtaining the train head positions and the train tail positions of two operation trains, and calculating the current train distance L between the current train headposition and the last train tail position; importing the running direction of the current train, the current train distance and the access speed limit into a constructed speed relation table to obtain speed control information of the current train; sending the speed control information of the current train to a vehicle-mounted controller of the current train to achieve safety control over the train distance between the trains, and the vehicle-mounted controller controls the running speed of the current train according to the situation that the speed of the current train is not larger than thespeed control information of the current train. The operation efficiency and the operation safety of the trains under the mine are improved, and the defect that a traditional single train is low in efficiency during operation is overcome.

Description

technical field [0001] The invention relates to the technical field of safe operation of underground trains in mines, in particular to a safety control method and system for unmanned driving vehicles in mines. Background technique [0002] At present, underground mines are mainly operated by rail locomotives. However, as the scale of underground mining continues to expand, the demand for reducing staff and increasing efficiency, improving transportation safety, and improving the working environment continues to increase. The use of unmanned driving has become a necessary trend. [0003] Now some mines have developed unmanned driving systems, but the systems are all based on the fixed block principle of "signal collection and closure". Only one train can run in the same section / route, and the rest of the trains need to be in a waiting position. state, which greatly affects the efficiency of mine transportation. Contents of the invention [0004] The purpose of the inventio...
