Automatic recognition truck loading and coal distributing system and method for mining use freight vehicles

Abstract

The invention discloses an automatic recognition truck loading and coal distributing system and method for mining use freight vehicles. An RFID vehicle recognition device and a coal transporting and truck loading system arranged on an entrance of a coal yard are included; the freight vehicles are loaded with coal through the coal transporting and truck loading system; the recognition device is connected with a coal distributing data server which is connected with a coal quality matching system and the coal transporting and truck loading system through a coal distributing controller; the coal quality matching system comprises a homogeneous mixing bin; a feeding port of the homogeneous mixing bin is provided with a plurality of raw coal inlets which are correspondingly connected with raw material coal in different coal qualities; a discharging port of the homogeneous mixing bin is in conveying connection with the coal transporting and truck loading system through a conveying belt; the conveying belt position of the discharging port of the homogeneous mixing bin is provided with a coal quality measuring sensor; the coal quality measuring sensor is in signal connection with the coal distributing data server; and the coal distributing data server controls discharging of the homogeneous mixing bin to be in linkage with the coal transporting and truck loading system by means of the coal distributing controller to achieve closed loop control of coal distributing quality and truck loading and coal distributing.

Description

technical field [0001] The invention relates to a coal blending system and method for automatic identification of trucks for mining. Background technique [0002] Different customers have different requirements for coal quality. Since the user's assessment standard for coal quality is the average ash content or average calorific value, the coal preparation plant adjusts the coal quantity of various coal types according to the user's requirements for coal quality, so that there is a relatively high requirement for the accuracy of coal blending, but As far as the current situation is concerned, most of the coal mines in my country have a low degree of automation in the loading and outbound transportation systems, and the general coal blending production is controlled manually (including manual rough calculation of the proportion, manual control of the start and stop of the coal feeder and manual adjustment of the coal feed quantity). However, the ash content or calorific value...

Problems solved by technology

Since the user's assessment standard for coal quality is the average ash content or average calorific value, the coal preparation plant adjusts the coal quantity of various coal types according to the user's requirements for coal quality, so that there is a relatively high requirement for the accuracy of coal blending, but As far as the current situation is concerned, most of the coal mines in my country have a low degree of automation in the loading and outbound transportation systems, and the general coal blending production is controlled manually (including manual rough calculation of the proportion, manual control of the start and stop of the coal feeder and manual adjustment of the coal feed quantity)

However, the ash content or calorific value of various coal types is constantly changing, and because the coal flow needs a certain amount of time to be transported on the belt, it is difficult to manually control the opening and closing of the coal feeder and the opening and closing of the gate. Guaranteed to meet the ash target required by the customer

[0003] On the other hand, from the perspective of social demand, the ash content of different coals has different prices in different markets. This manual method cannot effectively guarantee the stable quality of products, and the quality of coal blending often exceeds the standard. Claims or high quality and low prices, waste of resources, etc., will not only cause serious economic losses to the enterprise, but also cause adverse social impacts
