Problems solved by technology

[0002] The existing mine underground positioning system uses ZigBee radio frequency communication technology or WIFI radio frequency communication technology for underground communication connection, and uses RSSI ranging positioning method to realize the positioning of transportation equipment or underground personnel, but it is limited by the number of underground base stations. There is a phenomenon that radio frequency signals cannot be covered in some roadways or transportation channels, resulting in a large positioning blind spot in the existing underground ZigBee radio frequency communication network. Compared with underground personnel, underground transportation equipment has a wider moving range and faster moving speed. Faster, the frequency and probability of entering the positioning blind area is greater. Once the transportation equipment enters the positioning blind area, it will lose the communication connection with the control center on the well. Safety accidents are easy to occur underground in complex environments. Therefore, we propose a Radio-based underground mining communication positioning device and application method

Abstract

The invention discloses a radio-based underground mining communication positioning device and a method for using it. The positioning device includes a fixed anchor node, a mobile anchor node and an end node. The fixed anchor nodes are connected by optical fiber for communication. The fixed anchor node The communication connection between the node and the mobile anchor node and the fixed anchor node and the end node is carried out through ZigBee wireless communication technology, and the mobile anchor node and the end node are positioned by the RSSI ranging positioning method, and the distance between the mobile anchor node and the end node Communicate and connect through CSS wireless communication technology. The present invention sets two sets of positioning modules at the mobile anchor node and the terminal node, which can make up for the deficiency of the existing downhole communication positioning system, expand the area of ​​the positioning area, reduce the positioning blind area, and not only realize the precise positioning of the underground transportation equipment, but also can The operation safety of the underground transportation equipment is guaranteed, and the complexity and cost of the equipment are reduced.
