When operating the coal shearer, workers sometimes need to pay attention to the operating status of the conveyor to ensure the smooth progress of mining work.

[0003] In existing technology, conveyors are typically shut down via a centralized control system. This can be dangerous if the conveyor is slow to shut down due to sudden changes in coal flow or large coal lumps getting stuck. Furthermore, shutting down the conveyor can often delay production and reduce mining efficiency. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 It is a structural block diagram of a multi-device collaborative control working system for a coal mining face in an embodiment of the present invention. DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] <Example>

[0027] As attached Figure 1 As shown, this embodiment discloses a multi-device collaborative control system 100 for a coal mining face, which is used to control the operation of a shearer and conveyor (not shown) operating at the coal mining face. Specifically, the system 100 includes a conveyor electronic control system control module 10, a conveyor electronic control system communication module 20, a centralized control center host computer 30, a shearer electronic control system communication module 40, and a shearer remote control device 50.

[0028] The conveyor electric control system control module 10 is used to control the conveyor running speed.

[0029] The communication module 20 of the conveyor electric control system is used to transmit the real-time operation data of the conveyor to the host computer 30 of the centralized control center.

[0030] The host computer 30 of the centralized control center is used to receive the real-time operation data of the conveyor and send the data to the coal mining machine.

[0031] The communication module 40 of the electric control system of the coal mining machine is used to receive the operation data sent by the host computer 30 of the centralized control center.

[0032] The shearer remote control device 50 is connected to the shearer and is used to display the operating data of the conveyor so that the shearer operator can issue instructions for controlling the conveyor to slow down or shut down according to preset conditions.

[0033] In a preferred embodiment, the shearer remote control device 30 communicates with the shearer via wireless communication, facilitating operation by the shearer operator. Specifically, the shearer remote control device 50 includes a wireless communication module 51, which is wirelessly connected to the shearer electronic control system communication module 40 and is used to receive operating data from the conveyor or send commands to slow or shut down the conveyor.

[0034] In addition, data can be transmitted between the conveyor electronic control system communication module 20 and the coal mining machine electronic control system communication module 40 via wired or wireless means, and can be deployed according to the actual coal mining site environment.

[0035] In a preferred embodiment, the coal mining machine remote control device 50 also includes a vibration reminder module 52. When the operating data of the conveyor exceeds the preset alarm value, the vibration reminder module 52 reminds the coal mining machine operator through the vibration of the machine body, so that the operator can send corresponding control instructions in time.

[0036] In a preferred embodiment, the coal mining machine is provided with a remote control locking circuit for the conveyor, so as to control the conveyor to slow down or shut down through the remote control locking circuit.

[0037] Furthermore, the conveyor's operating data includes at least data corresponding to at least one of the following: the front chute, front chute tail, rear chute, rear chute tail, crusher, transfer conveyor, and belt conveyor. This data can be operating data for a single motor or multiple motors, enabling the shearer operator to make more precise control instructions. Specific operating data includes, but is not limited to, current, voltage, and power parameters.

[0038] In a preferred embodiment, the shearer remote control device 50 includes a display module 53 for displaying conveyor operating data and an operation module 54 for allowing the shearer operator to issue speed reduction or shutdown commands. The display module 53 allows the shearer operator to visually observe the conveyor's operating status and issue corresponding commands through the operation module 54, making this process simple, convenient, and quick.

[0039] For example, the specific conveyor control process can be:

[0040] After the coal mining machine operator makes the control instruction, it is sent to the coal mining machine electronic control system communication module 40 of the coal mining machine via the wireless communication module 51 in the coal mining machine remote control device 50, and further sent to the upper computer 30 of the centralized control center, and then sent by the upper computer 30 of the centralized control center to the conveyor electronic control system communication module 20, and then the conveyor electronic control system control module 10 makes the corresponding speed reduction or shutdown control.

[0041] In another case, when the coal mining machine operator makes an instruction to shut down the conveyor, it is sent to the coal mining machine electronic control system communication module 40 of the coal mining machine via the wireless communication module 51 in the coal mining machine remote control device 50, and then the coal mining machine electronic control system directly controls the remote control locking circuit of the conveyor to shut down the conveyor.

[0042] In another embodiment, the shearer remote control device 50 can also allow the shearer operator to issue commands to control the shearer to slow down. In actual production, if an unexpected situation occurs based on the real-time operating data of the conveyor and the shearer is not compatible with the conveyor, the shearer can be controlled to slow down to adapt to the conveyor's operating conditions. This can be achieved by reducing the shearer's traction speed. This is also a good solution to avoid overloading the conveyor and frequent shutdowns, thereby ensuring production efficiency.

[0043] Specifically, the system 100 also includes a shearer control module 60 for controlling the shearer's operating status. When a shearer operator issues a command to slow the shearer, the command is sent to the shearer's electronic control system communication module, which then controls the shearer to execute the command.

[0044] According to the multi-device collaborative control working system of the coal mining face involved in this embodiment, the real-time operating data of the conveyor is sent to the coal mining machine via the host computer of the centralized control center, and is synchronously displayed on the coal mining machine remote control device for the coal mining machine operator to view. This makes it convenient for the coal mining machine operator to match the conveyor with shutdown or speed reduction control according to the on-site production situation or the real-time operating conditions of the conveyor, thereby achieving multi-device collaborative control of the coal mining face, avoiding the situation where the conveyor is not shut down in time in an emergency, and avoiding the problem of low coal mining efficiency caused by frequent shutdown and startup of the conveyor, thereby effectively improving the coal mining efficiency.

[0045] The scope of protection of the present invention is not limited to the above-described embodiments. Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the scope and spirit of the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
