Description

Anti-collision system for underground ore-carrying truck Technical Field The utility model belongs to the technical field of mine safety, and particularly relates to an anti-collision system for an underground ore-carrying truck. Background In a mine downhole operation environment, a haul truck is an important conveyance. Due to narrow underground space, insufficient illumination and complex terrain, and severe conditions such as dust, wet skid and the like possibly exist, the vehicle is easy to collide during running. The traditional anti-collision method mainly depends on experience and visual judgment of a driver, and has great potential safety hazard. In the prior art, a single sensor (such as an ultrasonic sensor or an infrared sensor) is adopted to detect the obstacle, but the detection accuracy is lower in a complex underground mine environment, and a higher collision risk still exists. Disclosure of utility model The utility model aims to provide an anti-collision system for a downhole ore-carrying truck, which aims to solve the problems in the prior art in the background art. In order to achieve the above purpose, the utility model adopts the following technical scheme: An anti-collision system for an underground ore-carrying truck comprises a positioning tag, and a UWB positioning base station and an MU main control unit which are arranged on the underground ore-carrying truck; the positioning tag is carried by underground operators and is used for sending wireless coding signals; At least one UWB positioning base station is arranged, the UWB positioning base station is electrically connected with the MU main control unit, and the UWB positioning base station and the MU main control unit perform data transmission through an RS485 communication protocol; The mine truck is provided with an intermediate relay, the intermediate relay is respectively electrically connected with the MU main control unit and a parking valve of the mine truck, and the MU main control unit is used for controlling the parking valve to lose electricity and brake through the intermediate relay KM 1. The positioning tag is carried by underground operators, identity information of the positioning tag is pre-recorded into an MU main control unit, the positioning tag sends wireless coding signals to an UWB positioning base station, the UWB positioning base station transmits the signals to the MU main control unit, and the MU main control unit analyzes and calculates data so as to control a parking valve to lose electricity through an intermediate relay KM1, so that an ore transport truck is braked in time, and safety accidents are prevented.
