Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0028] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0030] In the following description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module" and "component" can be used interchangeably.

[0031] See attached Figure 1-2The present invention discloses a one-key start-stop method for the coal mining process, which can realize the unified control of the start and stop of each device in the entire coal mining system, that is, only one signal is needed to safely realize the start and stop of the main equipment of the entire coal mining process production chain, which is convenient and reliable. The control is based on the principle that when starting up, the equipment at the front of the coal mining process is started first, and when stopping, the equipment at the back of the coal mining process is stopped first; when a certain device in the equipment group that affects each other stops, other related equipment in the equipment group also needs to be stopped.

[0032] Specifically, when starting with one button, the priority of pump station > the priority of belt conveyor > the priority of crusher > the priority of transfer machine > the priority of scraper > the priority of coal mining machine > the priority of hydraulic support, then the starting order is: pump station, belt conveyor, crusher, transfer machine, scraper, coal mining machine, hydraulic support.

[0033] When one-button stop is used, the priority of hydraulic support > the priority of coal mining machine > the priority of scraper > the priority of transfer machine > the priority of crusher > belt conveyor, and the order of stopping is: hydraulic support, coal mining machine, scraper, transfer machine, crusher, belt conveyor.

[0034] Startup includes power-on and start-up operation. When power-on is normal, the operation starts automatically. Stopping includes stopping operation and power-off. The power can be turned off only when the operation stops completely.

[0035] It should be noted that since the coal mining machine is the last and most important equipment in the coal mining process, the operation of the coal mining machine is not a fully automatic process. Even if it can enter the operating state after normal power-on, it is also in a locked state at this time and requires manual operation by the operator, which can also be understood as unlocking. The coal mining machine can only enter the operating state after being unlocked, that is, it enters the actual operating state when it receives the unlocking signal.

[0036] In order to prevent a series of coal mining system failures caused by a single device failure, during the one-key startup process, it is necessary to detect the power-on status and operating status of the equipment in real time. Only when the power-on status and operating status are within the preset range will the next device be powered on.

[0037] In addition, during the operation of the equipment, it is also necessary to monitor the power-on status and operating status of each device in real time. When one or more of the power-on status and operating status are not within the preset range at the same time, it is regarded as a device failure, and the operation of the device is stopped. In order to comply with the shutdown principle, it is also necessary to stop the devices before the stop sequence of the device in sequence, and alarm to remind the operator to carry out maintenance and troubleshooting.

[0038] The one-button start process and the one-button stop process are controlled by the start-stop control module. The start-stop control module can be used to add devices or delete devices, or change the start sequence or stop sequence during the one-button start process and the one-button stop process.

[0039] Preferably, each device at the coal mining end is connected to the control end through a communication protocol. The number of devices at the coal mining end controlled by one-key start and stop can be increased by changing the settings of the communication protocol, that is, adding or deleting devices. The start and stop sequence of each device can also be changed through an algorithm.

[0040] It can be understood that the pump station, belt conveyor, crusher, transfer machine, scraper, coal mining machine, and hydraulic support mentioned in the present invention are not all the equipment controlled by one-key start and stop. More equipment can be added or some equipment can be deleted by changing the communication protocol to adapt to different actual coal mining processes. It is not limited to the coal mining scenarios of the above-mentioned equipment.

[0041] It also includes the start and stop of auxiliary equipment. Auxiliary equipment can be started in any process of one-key start and stopped in any process of one-key stop. Auxiliary equipment includes fans, gas fuel detection equipment, and spray equipment. In order to further optimize the coal mining process, ventilation work, gas fuel detection work, spray detection, etc. are carried out during the coal mining process. Even if the main equipment stops working, the auxiliary equipment can still work normally to optimize the coal mining environment.

[0042] Preferably, the power-on status includes monitoring of current value, voltage value, and power value; the operating status includes monitoring of temperature value, flow value, displacement value, inclination, and vibration value. However, it is not limited to this. For example, the operating status of a pump station also needs to include flow detection, and a conveyor, a transfer machine, etc. also needs to include load-bearing weight detection.

[0043] When the power-on status and / or operating status is abnormal, an alarm signal needs to be sent out at the device setting and the central control end at the same time to remind the on-site operator and the control personnel at the control end at the same time, thereby speeding up the dissemination efficiency of abnormal situation notification.

[0044] Preferably, during the one-button start and one-button stop process, the start and stop of each device is controlled by inserting a control signal; the priority of the inserted control signal is greater than the start sequence and the stop sequence. That is, the one-button start and stop sequence is the basic sequence, and when there are other external input control signals, the other external input control signals are the main ones. Usually, the other external input control signals are manual control signals.

[0045] Preferably, during the operation of the equipment, in addition to real-time monitoring of the power-on status and operating status of each device by the sensor device, the actual operating status of the coal mining machine can also be detected in real time with the camera device. The camera device needs to follow the coal mining machine.

[0046] In one preferred embodiment, a plurality of cameras are arranged on the operation route of the coal mining machine, and each camera rotates and follows the coal mining machine according to the position of the coal mining machine within a preset shooting range until the coal mining machine moves out of the preset shooting range. A plurality of cameras are distributed along the operation route of the coal mining machine, and rotate and follow the coal mining machine in turn, and the preset shooting ranges of two adjacent cameras overlap, and a plurality of cameras are used to obtain a full-line video of the operation route of the coal mining machine.

[0047] In this embodiment, the position of the camera device remains unchanged, and only the camera orientation and angle are changed according to the position of the coal mining machine. In another embodiment, the camera device can be a mobile device that moves simultaneously with the coal mining machine, such as a drone or a rail-mounted mobile camera device.

[0048] In the above preferred embodiment, further, an infrared receiver is provided on the hydraulic support, and an infrared sensor is provided on the coal mining machine. During the operation of the coal mining machine, the infrared sensor continuously transmits infrared signals to the infrared receiver, and the hydraulic support continuously obtains the position of the coal mining machine through the distance of the received infrared signal. The camera device is provided on the hydraulic support and is connected to the hydraulic support in communication, and the position of the coal mining machine can be obtained through the hydraulic support, so that the real-time position of the coal mining machine can be tracked.

[0049] The present invention also discloses a one-button start-stop system for the coal mining process, including a central control end and a coal mining end, wherein the coal mining end includes a pump station, a belt conveyor, a crusher, a transfer machine, a scraper, a coal mining machine, and a hydraulic support.

[0051] The central control terminal controls the one-key stop of the coal mining end. When the one-key stop is performed, the order of stopping is: hydraulic support, coal mining machine, scraper, transfer machine, crusher, belt conveyor. Starting includes power on and start operation; stopping includes stop operation and power off; the coal mining machine is locked after starting operation, and enters the actual operation state only when the unlocking signal is received.

[0052] The central control end also includes a monitoring system, which detects the power-on status and operating status of the device in real time during the one-key startup process. When the power-on status and operating status are within the preset range, the next device will be powered on.

[0053] The monitoring system also monitors the power-on status and operating status of each device in real time during the operation of the equipment. When the power-on status and / or operating status is not within the preset range, an alarm signal is sent to the central control end, and the central control end stops the operation of the device and stops the devices before the device in the stop order.

[0054] The central control terminal also includes a start-stop control module. The one-button start process and the one-button stop process are controlled by the start-stop control module. The start-stop control module can be used to add or delete devices, change the start sequence, or change the stop sequence during the one-button start process and the one-button stop process. The communication protocol is set on the start-stop control module.

[0055] It also includes the start and stop of auxiliary equipment, including but not limited to fans, gas fuel detection equipment, and spray equipment. Auxiliary equipment starts in any process of one-key start and stops in any process of one-key stop.

[0057] It also includes an alarm system, which is arranged at the coal mining end and the central control end.

[0058] The central control terminal also includes an insertion control module, through which an insertion control signal is sent. The insertion control module can be understood as a manually operated keyboard or button. During the one-key start and one-key stop process, the start and stop of each device are also controlled by the insertion control signal. The priority of the insertion control signal is greater than the start sequence and the stop sequence.

[0059] A number of cameras are provided on the operating route of the coal shearer. Each camera rotates and follows the coal shearer according to the position of the coal shearer within a preset shooting range until the coal shearer moves out of the preset shooting range. A number of cameras are distributed along the operating route of the coal shearer, and rotate and follow the coal shearer in turn, and the preset shooting ranges of two adjacent cameras overlap, so that a number of cameras can capture a full-line video of the coal shearer's operating route.
