Problems solved by technology

Unable to satisfy multi-branch linkage control
It is simple to adapt to the scene, and cannot meet the start-stop control of multiple branches in a coal flow with the same coal flow
[0006] 2. The PLC controller needs to customize the program according to the scene. For the frequently changing coal mining face and the changing overlapping relationship of the transport belt, the adaptability is poor. Every adjustment needs to reprogram the PLC program, which results in high labor costs and poor flexibility.

Embodiment 1

[0071] Such as figure 2 As shown, a mine belt conveyor start control method along the coal flow, comprising,

[0072] Classify the belts in each coal flow, the first belt in each coal flow is the belt of the upper level belonging to other coal flows, or the upper level belt in each coal flow is the belt of the third-party controller Belts, or belts without a previous belt in each coal stream;

[0073] In order to realize fast startup, during the startup process along the coal flow, the reverse query method is used, that is, the belt without the next-level belt is started first in the belt polling process. In addition, the coal flow start sign is used to indicate the start of the coal flow. For the convenience of memory, the start sign of the coal flow in this embodiment is represented by the number 1 (those skilled in the art can also use any other mark that is easy to remember).

[0074] In order to avoid garbled codes during function execution, and to ensure that the belt...

Embodiment 2

[0272] Such as image 3 As shown, a mine belt conveyor shutdown control method along the coal flow, corresponding to start along the coal flow, including,

[0273] The downtime sign of the coal flow is used to indicate that the coal flow is in the process of being shut down, and the present embodiment adopts the number 1 to represent it.

[0274] The stop failure flag is used to record that the running belt has failed to stop; by definition, the stop failure means that the running belt has not completed the stop process for more than the set number of times, and exits the coal flow stop function;

[0275] The stop overtime mark is used to record that the belt in the running stop has stopped for more than the preset time, and the stop overtime time is set as an empirical value, and can also be set according to actual needs;

[0276] The coal flow shutdown function traverses the coal flow belt, checks whether there is a shutdown failure flag or a shutdown timeout flag on the ru...

Abstract

The invention belongs to the field of belt transportation control in the coal mine industry, and in particular relates to a method and equipment for controlling the start and stop of a mine belt conveyor along the coal flow. The starting control method includes, starting along the coal flow includes obtaining the status of all the belts in the coal flow, and checking whether all the belts in the coal flow are running; if all the belts are running, it means that the coal flow is started successfully, and the starting flag along the coal flow is cleared; If there is a non-running belt, check whether the non-running belt is stopped or started. The technical solution of the application can perform multi-branch linkage control, and is suitable for frequently changing working faces and frequently changing overlapping relationships of transport belts.

Description

technical field [0001] The invention belongs to the field of belt transportation control in the coal mine industry, and in particular relates to a method and equipment for controlling the start and stop of a mine belt conveyor along the coal flow. Background technique [0002] The start-stop control of coal flow is the key link of coal flow transportation, which not only involves the normal transportation of coal flow, but also involves the switching between different coal flows. [0003] In order to achieve precise control of the start and stop of coal flow, the existing industry uses embedded equipment and uses PLC controllers for control. [0004] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the prior art has at least the following technical problems: [0005] 1. The coal flow start-stop control in the prior art is suitable for simple coal flow...
