Problems solved by technology

[0003] The mining belt conveyor transportation monitoring system currently on the market can simply start and stop the belt conveyor, but it is impossible to realize the automatic start, stop and speed regulation of the belt conveyors along the entire transportation line on site. , this is because the system lacks the data of the overall transport volume and the data of the material load of each belt conveyor, thus missing the basis for scheduling start, stop and speed regulation of the entire system
This is likely to cause coal piles or long-term idling when the belt conveyor is started and stopped during on-site use, affecting the normal production of the mine.
For example, although frequency converters have been installed in many sites, speed regulation cannot be performed due to unclear output of the entire mine and the overall load data of the belt conveyor, and it is only used as a soft start
During the operation of the belt conveyor, it runs at high speed under no-load, light-load and heavy-load conditions, while no-load and light-load conditions cause unnecessary damage to the motor, reducer, roller, idler, belt and other equipment. wear and power consumption, shortening the life of the equipment

Embodiment 1

[0032] Such as Figure 1-3 As shown, the automatic control method of the main transportation equipment based on the amount of coal produced in the mine is characterized in that: for the belt conveyor D1 that constitutes the main transportation system of the coal mine, it is started by the belt conveyor D0 on the upstream belt conveyor that overlaps it. The position of the material is determined by X0. When the material is transported to X0, D1 starts; its stop is determined by the total amount of material transported by the upstream belt conveyor overlapping with it W and the total amount of material transported by itself W1, when W=W1=0 , D1 stops; its transportation speed is determined by the output and the total amount of transportation on the current transportation line. If the current output is Wc1, the total upstream transportation volume of D1 is Wc2, and the maximum transportation volume of D1 is Wt (transportation volume per hour), per second The transportation volume...

Abstract

The invention provides a main transportation equipment automatic control method based on mine coal production amount. The main transportation equipment automatic control method based on the mine coalproduction amount is suitable for a system where belt conveyors are main transportation devices for mines, a material flow sensor is arranged in the system, transport volume data of the belt conveyorscan thus be detected, and the optimal control for all belt conveyors which form a coal mine main transportation line is realized through optimal scheduling of overall transport volume. The core content of main transportation equipment automatic control method based on the mine coal production amount is that according to transport volume information of the belt conveyors, the multi-dependency relation of rubber belt machines and operation of equipment, the overall transport volume of the belt conveyors on the whole transportation line is taken as input to control starting, stopping and speed adjustment of each belt conveyor in real time.

Description

technical field [0001] The invention relates to a control system of a coal mine main conveyor belt conveyor and a material flow detection device for a mine belt conveyor, in particular to an automatic control method for the main conveyor equipment based on the amount of coal produced in a mine. Background technique [0002] At present, the belt conveyor has high coal transportation efficiency and is the main equipment of the main transportation system of the coal mine. With the increasing automation of coal mine production, users have more and more demands on the technology and intelligence of the on-site coal flow control system. higher requirements. [0003] The mining belt conveyor transportation monitoring system currently on the market can simply start and stop the belt conveyor, but it is impossible to realize the automatic start, stop and speed regulation of the belt conveyors along the entire transportation line on site. , this is because the system lacks the data o...
