Abstract

The invention relates to a vehicle-mounted coal quality detection method. A laser ranging device is used for acquiring height data of the surface of vehicle-mounted coal, and operating is carried out by a computer device according to the acquired height data; the laser ranging device is provided with a box-type cross beam, and the box-type cross beam is provided with multiple ranging laser heads at equal intervals along a straight line; the two ends of the box-type cross beam are respectively provided with a travelling device, the two travelling devices are respectively arranged on two elevated rails which are arranged in parallel; the computer device is internally provided with a serial communication card, a data acquisition card and matched data processing software, and a height data output terminal of each ranging laser head is electrically connected with a height data input terminal of the computer device; and the computer device is internally provided with a PLC (programmable logic controller), and the PLC is used for controlling the travelling device. The vehicle-mounted coal quality detection method disclosed by the invention can realize rapid and accurate detection on quality of vehicle-mounted coal; and the vehicle-mounted coal quality detection method can provide an effective method and approach for monitoring coal quality when being combined with a weighing device.

Description

technical field [0001] The invention relates to a vehicle-mounted coal quality detection method and device. The invention uses a laser ranging device to collect the height data of the vehicle-mounted coal surface, and uses a computer device to perform calculation and processing according to the collected height data. Background technique [0002] Mine truck transportation is one of the important ways of coal mine transportation. At present, the mine car measures raw coal mainly by using an electronic weighing device to weigh the mine car. After obtaining the total mass of the mine car and raw coal, the main controller of the measurement automatically deducts the tare weight of the mine car to obtain the weight of the mine car loaded with raw coal. In the process of transportation, there is fraudulent behavior of replacing high-quality coal with low-quality coal. Chinese patent CN 101718576 A proposes a mine car measurement monitoring system based on image processing. The i...
