[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Combine the following Figure 1-Figure 7 The invention describes a remote control method and device for working face equipment.

[0027] Figure 1 It is one of the flow charts of the remote control method of the working face equipment provided by the present invention, which is applied to a node controller, wherein the node controller is arranged at multiple nodes in the working face and the tunnel, and the node controller is connected to the central control system of the remote control center, and the node controller includes an input device.

[0028] The node controller refers to a device set at a node to control the operating status of the working face equipment. For example, the node controller can be an electro-hydraulic controller set on a bracket, which can determine the brackets with a specified number of distances between the first node bracket and the second node bracket arranged on the working face and the lane as adjacent nodes. The node controller can be connected to the central control system of the remote control center through a communication network, and the communication network can be Ethernet, etc.

[0029] like Figure 1 As shown, the method includes: Step 101: Receive a user input instruction generated by an input device at the node.

[0030] The input device of the node controller refers to a device used by a user to interact with the node controller to send an operation instruction or set parameters. Exemplarily, the input device of the node controller can be a button panel, a touch screen control panel, or a joystick.

[0031] It is understandable that there are multiple node controllers, each of which can be arranged at a node in the working face or a node in the lane. A user can generate a user input instruction for a single working face device or multiple working face devices through an input device at a node.

[0032] For example, the working face equipment may include coal mining equipment, scrapers, transfer machines and crushers, and the user may be a support operator. When the support operator is inspecting the working face equipment or in an emergency, he can operate the buttons such as "coal mining equipment lock", "coal mining equipment emergency stop", "scraper lock", "scraper emergency stop", "transfer machine lock", "transfer machine emergency stop", "crusher lock", "crusher emergency stop" through the button panel of the node controller to generate corresponding user input instructions.

[0033] Step 102: Determine at least one target working surface device and a corresponding target device status signal from the plurality of working surface devices based on the user input instruction.

[0034] The multiple working surface devices refer to multiple working surface devices in the same working surface area as the node controller.

[0035] The target working face equipment refers to the working face equipment corresponding to the user input instruction. For example, if the user input instruction is a user input instruction generated by operating the "coal mining machine equipment lock" button, then one target working face equipment and a corresponding target equipment status signal are determined. If the user input instruction is a user instruction generated by operating the "coal mining machine equipment lock" and "scraper lock" buttons, then two target working face equipment and corresponding target equipment status signals are determined.

[0036] The target device state refers to the operating state of the target working face device set by the user input command. The target device state signal refers to the signal that transmits the target device state set by the user input command, and is used to control the target working face device to perform an operation to change the device state. For example, the target device state signal determined by the user instruction generated by operating the "coal mining machine equipment locking" button is a signal that controls the coal mining machine equipment to perform the coal mining machine equipment locking operation.

[0037] Step 103: Send the target device status signal to the central control system; wherein the central control system is used to determine the corresponding target working surface device according to the target device status signal, and send the target device status signal to the target working surface device.

[0038] Exemplarily, the node controller can send a target device status signal or multiple target device status signals to the central control system via Ethernet. The central control system can determine the corresponding target work surface device based on the received target device status signal, and send each target device status signal to the corresponding target work surface device via Ethernet.

[0039] Step 104: Receive the current device status corresponding to the at least one target working surface device returned by the central control system, and display it to the user at the corresponding node; wherein the current device status is the device status after the at least one target working surface device receives the corresponding target device status signal and performs adjustment.

[0040] The current equipment status refers to the actual operating status of the target working face equipment at the current moment, which can be determined by the equipment data collected in real time by sensors, control systems, monitoring systems, etc.

[0041] Exemplarily, the node controller may include a display screen. After receiving the target device status signal, the target working surface device performs the operation corresponding to the target device status signal, and can send its own current device status to the central control system via Ethernet. The central control system can send the current device status of the target working surface device to the node controller via Ethernet, and the node controller can display the current device status of the target working surface device via the display screen.

[0042] Compared with the voice call effect to notify the remote monitoring center user, the remote monitoring center user performs the operation to control the target work surface equipment. The remote control method of the work surface equipment provided by the embodiment of the present invention receives the user input instruction generated by the input device at the node, determines at least one target work surface equipment and the corresponding target equipment status signal from multiple work surface equipment based on the user input instruction, sends the target equipment status signal to the central control system, receives the current equipment status of the target work surface equipment returned by the central control system, and displays it to the user at the corresponding node. It can facilitate the forwarding of the target equipment status signal to the target work surface equipment through the central control system, control the target work surface equipment to perform the corresponding operation, and thus quickly and effectively operate the work surface equipment in an emergency.

[0043] Based on the above embodiment, the working face equipment includes coal mining machine equipment, a scraper, a transfer machine and a crusher, and the central control system includes a node control module, a coal mining machine equipment control module and a centralized control module. The node control module is connected to the coal mining machine equipment control module and the centralized control module respectively, the node controller is connected to the node control module, the coal mining machine equipment is connected to the coal mining machine equipment control module, and the scraper, the transfer machine and the crusher are connected to the centralized control module.

[0044] The node control module may also be referred to as a node control unit, a node control subsystem, etc., the coal mining machine equipment control module may also be referred to as a coal mining machine equipment control unit, a coal mining machine equipment control subsystem, etc., and the centralized control module may also be referred to as a centralized control unit, or a subsystem, etc. The node control module may be connected to the coal mining machine equipment control module and the centralized control module by communication or by electrical connection.

[0045] Scrapers, transfer machines and crushers can be collectively referred to as centralized control equipment.

[0046] like Figure 2 As shown, sending the target device status signal to the central control system specifically includes: sending the target device status signal to the node control module.

[0047] Exemplarily, a coal mining machine equipment start / stop signal, a coal mining machine equipment front drum raising / lowering signal, and a coal mining machine equipment rear drum raising / lowering signal can be sent to the coal mining machine equipment control module through the node control module, and forwarded to the coal mining machine equipment through the coal mining machine equipment control module to control the coal mining machine equipment start / stop, the coal mining machine equipment front drum raising / lowering, and the coal mining machine equipment rear drum raising / lowering. A centralized control equipment start / stop signal can be sent to the centralized control module through the node control module, and forwarded to the centralized control equipment through the centralized control module to control the centralized control equipment start / stop, etc.

[0048] like Figure 3 As shown, receiving the current device status corresponding to the at least one target working surface device returned by the central control system specifically includes: Receiving the current equipment status of the coal mining machine equipment sent by the coal mining machine equipment control module and forwarded by the node control module; or Receive the current equipment status of the scraper, the transfer machine and / or the crusher sent by the centralized control module and forwarded by the node control module.

[0049] For example, the coal mining machine equipment control module receives the front drum raising / lowering, rear drum raising / lowering, and start / stop of the coal mining machine equipment, and forwards it to the node controller through the node control module; the centralized control module receives the start / stop of the centralized control equipment, and forwards it to the node controller through the node control module, etc.

[0050] For example, the coal mining machine equipment can send the current equipment status to the coal mining machine equipment control module via Ethernet, and the coal mining machine equipment control module can send the received current equipment status of the coal mining machine equipment to the node control module via a communication connection, and the node control module can send the received current equipment status of the coal mining machine equipment to the node controller. The scraper, transfer machine or crusher can send the current equipment status to the centralized control module via Ethernet, and the centralized control module can send the received current equipment status of the centralized control device to the node control module via a communication connection, and the node control module can send the received current equipment status of the centralized control device to the node controller.

[0051] Compared with auxiliary equipment in the coal mining process such as scrapers, transfer machines and crushers, users' control over coal mining equipment may be more complex and frequent. For example, controlling the rotation, advancement speed, cutting depth, etc. of the coal mining cutter head of the coal mining equipment. In order to improve the real-time control of the coal mining equipment, in this embodiment, by separately setting up the coal mining equipment control module and the centralized control module, the communication between the scraper, transfer machine and crusher and the centralized control module can be avoided, which affects the communication between the coal mining equipment and the coal mining equipment control modules, thereby avoiding delays in data transmission between the coal mining equipment and the coal mining equipment control modules.

[0052] It takes a certain amount of time for the target working surface equipment to convert from the current equipment state to the target equipment state. In order to facilitate notifying the user whether the target working surface equipment is converting the equipment state normally or converting the equipment state abnormally, based on any of the above embodiments, after receiving the current equipment state corresponding to the at least one target working surface equipment returned by the central control system, the method also includes: when the current equipment state corresponding to the at least one target working surface equipment is different from the target equipment state and the target equipment state signal is locked, displaying a device state adjustment mark to the user; wherein the device state adjustment mark is used to indicate that the target working surface equipment is in the process of adjusting the equipment state.

[0053] For example, when the target working face equipment is a coal mining machine, and the target working face equipment is in a normal conversion equipment state, the equipment state adjustment mark may be a text mark "coal mining machine equipment is being locked", or an image mark indicating that the coal mining machine equipment is being locked, etc. When the target working face equipment is in an abnormal conversion equipment failure, the equipment state adjustment mark may be a text mark "coal mining machine equipment locking failure", or an image mark indicating that the coal mining machine equipment is locked, etc.

[0054] Specifically, it is possible to determine whether the target working face equipment is in a normal equipment conversion state or an abnormal equipment conversion failure based on the specific signal parameters of the current equipment state sent by the target working face equipment. It is also possible to determine whether the target working face equipment is in a normal equipment conversion state or an abnormal equipment conversion failure based on preset rules, such as the duration of the target working face equipment in the current equipment state.

[0055] In another embodiment, after receiving the current equipment state corresponding to the at least one target working surface equipment returned by the central control system, the method further includes: When the current device state corresponding to the at least one target working surface device is different from the target device state and the target device state signal is used to adjust the operation strategy, the real-time device state of the target working surface device is displayed to the user.

[0056] Adjusting the operation strategy refers to adjusting the working parameters of the target working face equipment. For example, controlling the up / down of the front drum of the coal mining machine equipment and controlling the up / down of the rear drum of the coal mining machine equipment. For example, when the target working face equipment is a coal mining machine equipment, the target equipment status signal is used to adjust the working parameters of the coal mining machine equipment, indicating that the deceleration value of the front drum of the coal mining machine increases by 10 units, and showing the user the current actual deceleration value of the front drum of the coal mining machine equipment; when the target working face equipment is a scraper, the target equipment status signal is used to adjust the working parameters of the scraper, indicating that the deceleration signal value of the scraper increases by 5 units, and showing the user the current actual deceleration of the scraper.

[0057] Figure 4 The second flow chart of the remote control method of the working face equipment provided by the present invention is applied to a central control system, the central control system is arranged in a remote monitoring center, and the central control system is connected to at least one working face equipment, such as Figure 4 As shown, the method includes: Step 401: Determine at least one target device status signal; Step 402: determining a corresponding target working surface device from a plurality of working surface devices based on the at least one target device status signal, and sending the target device status signal to the corresponding target working surface device; Step 403, receiving the current device status sent by the target working surface device, and displaying it to the user at the remote monitoring center; wherein the current device status is the device status after the target working surface device receives the device startup status signal and performs adjustments.

[0058] Compared with only the working face personnel monitoring the operating status of the target working face equipment, the remote control method of the working face equipment provided by the embodiment of the present invention determines at least one target device status signal, determines the corresponding target working face equipment from multiple working face equipment based on at least one target device status signal, and sends the target device status signal to the corresponding target working face equipment, receives the current equipment status sent by the target working face equipment, and displays it to the user at the remote monitoring center. This can facilitate the user at the remote monitoring center to monitor the target working face equipment and cooperate with the working face personnel to quickly and effectively operate the working face equipment in an emergency.

[0059] Based on any of the above embodiments, the central control system is connected to at least one node controller; Determining at least one target device status signal specifically includes: Accept at least one target device status signal sent by the node controller to the central control system.

[0060] Compared with the voice call effect of notifying the remote monitoring center user, the remote monitoring center user performs operations to control the target working face equipment. The remote control method and device of the working face equipment provided in this embodiment can forward the target device status signal sent by the node controller at the receiving node to the corresponding target device, and control the target working face equipment to perform corresponding operations, thereby facilitating the rapid and effective operation of the working face equipment in an emergency situation.

[0061] During emergency handling of the working face or target working face equipment or during maintenance of the target working face equipment, if operations such as accidental touches occur, serious production accidents will occur. In order to reduce the risk of operations such as accidental touches, based on any of the above embodiments, the target device status signal includes an equipment startup status signal; before sending the target device status signal to the target working face equipment, the method also includes: when determining that the target device status signal is the equipment startup status signal sent by the node control module, determining that the user input at the remote monitoring center is confirmation of sending the equipment startup status signal.

[0062] For example, the user at the remote monitoring center can input a confirmation signal of the device startup status after confirming with the work surface personnel.

[0063] In this embodiment, when the target working face equipment is converted from a stopped state to a started state, the equipment start-up status signal can be forwarded to the target working face equipment only after the user at the remote monitoring center makes a second confirmation, which can reduce the risk of production accidents caused by operations such as accidental touches.

[0064] In order to improve the reliability of the system, based on any of the above embodiments, the central control system includes an input device; before determining at least one target device status signal, the method also includes: accepting a user input instruction generated by the input device at the remote monitoring center; determining at least one target device status signal, specifically including: determining at least one target working surface device and a corresponding target device status signal from a plurality of the working surface devices based on the user input instruction.

[0065] The input device of the central control system may be a button panel, a touch screen control panel or a joystick.

[0066] It is understandable that, when the current device state of the target working surface device is a stopped state, after accepting the user input instruction generated by the input device at the remote monitoring center and determining the target working surface device based on the user input instruction, the target device state signal corresponding to the target working surface device will not be determined based on the user input instruction. Exemplarily, the central control system may include a display screen, and when the current device state of the target working surface device is a stopped state, after accepting the user input instruction generated by the input device at the remote monitoring center, a prompt message of "target working surface device locking request" may be displayed to the user through the display screen.

[0067] In this embodiment, by setting up a target device status signal determined by a user input instruction generated by an input device at a remote monitoring center, and a target device status signal sent by a node controller to determine the target device status signal, a redundant mechanism is formed, which can maintain normal operation when one of the systems fails, thereby improving the reliability of the system.

[0068] like Figure 5 As shown, based on any of the above embodiments, the central control system includes a node control module, a coal mining machine equipment control module and a centralized control module, the node control module is connected to the coal mining machine equipment control module and the centralized control module respectively, the node controller is connected to the node control module, the coal mining machine equipment is connected to the coal mining machine equipment control module, and the scraper, the transfer machine and the crusher are connected to the centralized control module; Determining a corresponding target working surface device from a plurality of working surface devices based on the at least one target device status signal specifically includes: The node control module sends the target device status signal to the coal mining machine equipment control module based on the signal type of the at least one target device status signal, and determines the coal mining machine equipment corresponding to the target device status signal; or The node control module sends the target device status signal to the centralized control module based on the signal type of the at least one target device status signal, and determines the scraper, the transfer machine and / or the crusher corresponding to the target device status signal; Receiving the current equipment status sent by the target working surface equipment specifically includes: accepting the current equipment status sent by the coal mining machine equipment to the coal mining machine equipment control module, or Accept the current equipment status sent by the scraper, the transfer machine and / or the crusher to the centralized control module.

[0069] Among them, the signal types of the target equipment status signal may include coal mining machine equipment signals and centralized control equipment signals, and the centralized control equipment signals may include scraper signals, transfer machine signals and crusher signals, etc.

[0070] In order to specifically illustrate the functions of the remote control method for working face equipment provided by this embodiment, a specific example is provided below.

[0071] The central control system of the remote control center includes a node control module, a coal mining machine equipment control module and a centralized control module. The node control module is connected to the coal mining machine equipment control module and the centralized control module respectively.

[0072] The working face equipment includes coal mining equipment, scrapers, transfer machines and crushers. The coal mining equipment is connected to the coal mining equipment control module, and the scrapers, transfer machines and crushers are connected to the centralized control module. The node controller is connected to the node control module.

[0073] The node controller includes a button panel. In the case of joint multi-device locking, it can receive user input instructions generated by the user at the node operating the buttons such as "coal mining machine equipment locking", "coal mining machine equipment emergency stop", "scraper machine locking", "scraper machine emergency stop", "transfer machine locking", "transfer machine emergency stop", "crusher locking", "crusher emergency stop", etc. through the button panel, and determine the coal mining machine equipment and the corresponding coal mining machine equipment locking state signal, coal mining machine equipment emergency stop state signal from multiple working face devices based on the user input instructions, determine the scraper machine and the corresponding scraper machine locking state signal, scraper machine emergency stop state signal, determine the transfer machine and the corresponding transfer machine locking state signal, transfer machine emergency stop state signal, determine the crusher and the corresponding crusher locking state signal, crusher emergency stop state signal; it can be understood that the button can also be called a shortcut key or a shortcut operation function, etc. The node controller sends the locking state signal of the coal mining machine equipment, the emergency stop state signal of the coal mining machine equipment, the locking state signal of the scraper machine, the emergency stop state signal of the scraper machine, the locking state signal of the transfer machine, the emergency stop state signal of the transfer machine, the locking state signal of the crusher, and the emergency stop state signal of the crusher to the node control module through Ethernet.
