Coal flow control device based on CAN bus

Abstract

The invention discloses a coal flow control device based on a CAN bus. The coal flow control device based on the CAN bus comprises an MCU module (1). A CAN module (3), a display screen (5) and buttons (6) are arranged on the periphery of the MCU module (1), wherein the CAN module (3), the display screen (5) and the buttons (6) are all connected with the MCU module (1). A power source (2) supplying power to the control device is further arranged on the periphery of the MCU module (1). The input of the MCU module (1) is connected with an on-off status sensor (7) and a start-stop sensor (8) of the belt conveyer (10). The output of the MCU module (1) is connected with a protective device host (9) driving the belt conveyer (10). For a coal mine site with multiple belt conveyers, each belt conveyer is provided with the flow control device, the flow control devices conduct communication through the CAN bus, each flow control device conducts centralized control over the corresponding belt conveyer based on signals fed back by the on-off status sensor and the start-stop sensor of the flow control device according to the needs, start and stop are intelligently conducted according to the conditions of coal on each belt conveyer, idling of each belt conveyer is avoided, and electricity is greatly saved.

Description

technical field [0001] The invention relates to the field of coal mine control equipment, in particular to a coal flow control device based on CAN bus. Background technique [0002] At present, belt conveyors are widely used in the transportation of coal mining areas. Due to the long distance from the working face to the mining area, a series of belt conveyors are often used for joint operations, sometimes with up to 10 belt conveyors. Many, but currently the control of conveyors can be controlled by a single machine. Each conveyor is controlled separately through the protection and control host. Each protection and control host can only control the belt conveyor connected to it. In practical applications, due to the The two-type conveyors operate independently, and cannot be intelligently controlled to start and stop according to the coal loading situation on the conveyor. Often, the coal on the conveyor cannot be found and stopped in time after the coal on the conveyor is ...

[0002] At present, belt conveyors are widely used in the transportation of coal mining areas. Due to the long distance from the working face to the mining area, a series of belt conveyors are often used for joint operations, sometimes with up to 10 belt conveyors.

Each protection and control host can only control the belt conveyor connected to it. In practical applications, due to the The two-type conveyors operate independently, and cannot be intelligently controlled to start and stop according to the coal loading situation on the conveyor, which often causes the coal on the conveyor to be empty and cannot be found in time to stop, resulting in long-term idling of the conveyor, resulting in a large waste of electric energy
