Adaptive start-stop method for forward and reverse coal flow in mine transportation system

Abstract

The invention discloses a forward and reverse coal flow self-adaption machine starting and stopping method of a coal transport system. The method comprises the steps that 1, the coal transport system is initialized; 2, a belt conveyor of the present level is started; 3, whether a belt conveyor of a former level is allowed to operate is judged; 4, the belt conveyor of the former level is controlled to start to operate, specifically, 401, a starting signal of the belt conveyor of the former level is given, 402, whether the belt conveyor of the former level is an Nth belt conveyor or not is judged, 403, operation of the Nth belt conveyor is controlled, 404, starting of the belt conveyor of the former level in a reverse coal flow state is determined, and 405, the operation signal of the belt conveyor of the former level is detected, and whether the belt conveyor of the present level operates in a forward coal flow state or not is judged; and 5, starting and stopping of the belt conveyor transport system in the reverse coal flow mode are controlled. Starting and stopping of the transport system in the forward and reverse coal flow modes can be achieved, a priority is given to the forward coal flow mode, the idle running time of the belt conveyors is shortened to the greatest extent, energy consumption is reduced, the cost is reduced, and profits are increased.

Description

technical field [0001] The invention belongs to the technical field of starting and stopping of belt conveyors, and in particular relates to an adaptive starting and stopping method of forward and reverse coal flow in a mine transportation system. Background technique [0002] With the development and progress of automation technology and the positive response to the company's lean production, more humanized and intelligent designs are applied to mining production applications to reduce the waste of resources such as manpower and material resources, so as to make the best use of materials and talents. The coal industry started very early, but the technical improvement is relatively slow, mainly due to the limitation of underground environmental factors. The application of belt conveyors in coal mines saves manpower and improves transportation efficiency. However, the belt start-stop process usually uses reverse start The parallel stop technology mainly considers the belt tra...

Problems solved by technology

The coal industry started very early, but the technical improvement is relatively slow, mainly due to the limitation of underground environmental factors. The application of belt conveyors in coal mines saves manpower and improves transportation efficiency. However, the belt start-stop process usually uses reverse start The parallel stop technology mainly considers the belt transport power limit, reverse start and parallel stop prevents the belt from piled up with coal, once the coal piles up, it will easily cause damage to the belt transportation, seriously affect the production, and cause great economic losses and dangers to the coal mine, but many When the long-distance belt conveyor is started against the coal flow, the near-ground belt conveyor runs for a long time, which wastes belt transportation resources
