Mine car detection device and method for identifying coals and gangues and preventing cheating

Abstract

The invention discloses a mine car detection device and a method for identifying coals and gangues and preventing cheating. The device comprises a weighing sensor arranged on a track, a laser detector positioned right above the weighing sensor, a camera arranged laterally above the track, and a controller connected with the camera and the weighing sensor, wherein the weighing sensor is used for detecting the actual weight of materials carried by mine cars; the laser detector is used for generating line laser rays for calibrating the top line shape of the materials carried by the mine cars; the camera is used for acquiring image data having the top line shape calibrated by the laser detector in real time; and the controller is used for receiving the actual weight detected by the weighing sensor, counting the running mine cars according to the received image data from the camera, and calculating the standard weight of the materials carried by the mine cars according to the received image data from the camera. The device and the method can realize the accurate identification of the coals and the gangues, and prevent cheating behaviors in weighing the materials carried by the mine cars.

Description

technical field [0001] The invention relates to a coal mine detection system, in particular to a mine car detection device and method for identifying coal gangue and preventing cheating. Background technique [0002] Electronic mine truck scales are widely used in small coal mines that use mine cars as a means of coal production and transportation, especially in the remote monitoring system of mine output. The mine car runs on the track. When it runs on the guide rail of the electronic mine car scale, the direction sensor set on the guide rail detects the running direction of the mine car, and the weighing sensor detects the weight of the mine car. The direction sensor and The load cell transmits the measurement data to the remote monitoring system for monitoring. However, the staff at the mine can avoid paying taxes by placing some cheating tools on the load cell so that the load cell cannot detect the weight of the mine car. In addition, it is also required to identify w...
