Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0022] The hydraulic support control system of the present application is described in detail below using an embodiment.

[0023] Figure 1 A schematic diagram of the structure of a hydraulic support control system provided in an embodiment of the present application.

[0024] like Figure 1 As shown, the hydraulic support control system 1000 in this embodiment includes: a hydraulic support controller 101, a wireless base station 102, a power box 103, an isolation coupler 104 and a handheld terminal 105.

[0025] Among them, the hydraulic support controllers 101 are connected in series, a wireless base station 102 is configured for every N hydraulic support controllers 101, and a power box 103 and an isolation coupler 104 are configured for every M hydraulic support controllers 101, wherein each wireless base station 102 includes multiple wireless communication modules 20, and each hydraulic support controller is configured with a wireless communication module 20, and N and M are positive integers.

[0026] It should be noted that the hydraulic support controller is installed on each hydraulic support and is connected in series in sequence via cables.

[0027] Optionally, the hydraulic support controller is a core component of the hydraulic support control system, and can be used for support movement, sensor data collection and data communication, etc.

[0028] It should be noted that the present application does not limit the value range of N, and it can be set according to actual conditions. Optionally, the value range of N can be set to [6-8].

[0029] For example, when the value of N is 6, a wireless base station 102 may be configured for every 6 hydraulic support controllers 101 .

[0030] Among them, each wireless base station is relatively independent and does not communicate with the hydraulic support controller by wire.

[0031] It should be noted that the present application does not limit the value of M, and it can be set according to actual conditions. Optionally, the value of M can be set to 10.

[0032] For example, when the value of M is 10, a power supply box 103 and an isolation coupler 104 may be configured for every 10 hydraulic support controllers 101 .

[0033] The power box 103 is used to provide power to the hydraulic support controller 101 and the wireless communication module 20 .

[0034] In the embodiment of the present application, the power supply box 103 is a flameproof and intrinsically safe power supply box.

[0035] The isolation coupler 104 is used to implement power isolation and signal coupling of the hydraulic support controller 101 .

[0036] It should be noted that the isolation coupler 104 can use photoelectric isolation technology to transmit digital signals and isolate electrical signals, thereby achieving signal transmission in the entire hydraulic support control system.

[0037] Among them, the wireless communication module 102 is used to respond to the handheld terminal 105 establishing a connection with the hydraulic support controller 101. The wireless communication module 102 configured in the hydraulic support controller 101 is converted from a dormant state to an activated state to establish a wireless communication connection with the handheld terminal 105.

[0038] It should be noted that the hydraulic support control system proposed in the relevant technology can realize hydraulic support control and sensor data monitoring based on interactive communication between the remote control and the hydraulic support controller. However, it often increases the wireless communication energy, resulting in the consumption of intrinsically safe power supply energy. Among them, the intrinsically safe power supply energy is limited by safety (limited to 24W), resulting in the number of hydraulic support actions supported during remote control is less than when the support controller is directly operated, which affects the actual application of hydraulic support control.

[0039] It should be noted that, for the hydraulic support control system proposed in the present application, when the hydraulic support control system is powered on, the wireless communication modules corresponding to all hydraulic support controllers are in a dormant state (off state) to minimize the power consumption of the equipment itself; when the handheld terminal establishes a connection with the hydraulic support controller, only the wireless communication module corresponding to the connected hydraulic support controller is activated, and only the wireless communication module corresponding to the connected hydraulic support controller establishes a wireless communication connection with the handheld terminal to reduce power consumption.

[0040] The handheld terminal 105 is used to send a hydraulic support action instruction and control the hydraulic support according to the hydraulic support action instruction.

[0041] Optionally, the handheld terminal may be a remote controller, which sends a hydraulic support action instruction and controls the hydraulic support according to the hydraulic support action instruction.

[0042] It should be noted that when the hydraulic support control system has a wireless communication function, it can be applied to a variety of scenarios, such as: remotely controlling the action of the hydraulic support through the wireless communication function, and checking the sensor information connected to the hydraulic support support; another example: realizing the relative distance perception and positioning between personnel and equipment through the wireless communication function, realizing the safe control of the hydraulic support control system, and protecting personnel safety; another example: building a wireless communication link through the wireless communication function as a redundant channel for communication between support controllers, to ensure the reliable execution of the hydraulic support control system.

[0043] The hydraulic support control system provided in the embodiment of the present application includes a hydraulic support controller, a wireless base station, a power box, an isolation coupler and a handheld terminal, wherein the hydraulic support controllers are connected in series, a wireless base station is configured for every N hydraulic support controllers, and a power box and an isolation coupler are configured for every M hydraulic support controllers, wherein each wireless base station includes multiple wireless communication modules, each hydraulic support controller is configured for a wireless communication module, N and M are positive integers, the power box is used to provide power for the hydraulic support controller and the wireless communication module, the isolation coupler is used to achieve power isolation and signal coupling of the hydraulic support controller, the wireless communication module is used to establish a connection with the hydraulic support controller in response to the handheld terminal, the wireless communication module configured in the hydraulic support controller is converted from a dormant state to an activated state, and a wireless communication connection is established with the handheld terminal, the handheld terminal is used to send a hydraulic support action instruction, and the hydraulic support is controlled according to the hydraulic support action instruction. The hydraulic support control system proposed in the present application reduces the power consumption and complexity in the process of controlling the hydraulic support, reduces the energy consumption of online equipment under the premise that the output energy of the intrinsically safe power supply is limited, increases the number of remotely controlled hydraulic supports, and can accurately achieve remotely controlled support actions, thereby improving coal mining efficiency.

[0044] In some embodiments, the hydraulic support controller 101 is further used to transmit the controller information of the hydraulic support controller 101 and the communication information of the wireless communication module 20 back to the corresponding wireless base station 102 .

[0045] Optionally, the controller information may be hydraulic support number information and connection status information corresponding to the hydraulic support controller.

[0046] Optionally, the communication information may be communication quality information, communication speed information, etc.

[0047] In some embodiments, the wireless base station 102 is further used to: receive controller information and communication information, and store the controller information and communication information.

[0048] In some embodiments, the wireless communication module 20 is also used to: in response to a failure of the wired communication link between the adjacent first hydraulic support controller and the second hydraulic support controller, the first wireless communication module corresponding to the first hydraulic support controller and the second wireless communication module corresponding to the second hydraulic support controller are converted from a sleep state to an active state, and a wireless communication link between the first hydraulic support controller and the second hydraulic support controller is established through the first wireless communication module and the second wireless communication module.

[0049] For example, Figure 2 As shown, when the wired communication link between two adjacent hydraulic support controllers fails, the wireless communication modules corresponding to the two hydraulic support controllers are converted from a dormant state to an active state, and a "point-to-point" connection is established to build a wireless communication link between the two hydraulic support controllers.

[0050] Optionally, when a wired communication link between two adjacent hydraulic support controllers fails, the adjacent hydraulic support controllers may report their respective states and wired link failure information to the wireless base station.

[0051] In some embodiments, the wireless base station 102 is also used to: monitor whether the wireless communication link is abnormal through heartbeat communication, and in response to the hydraulic support controller not receiving heartbeat communication within a fixed time, determine that the wireless communication link is abnormal, disconnect the wireless communication link, and disconnect the support action of the hydraulic support controller.

[0052] For example, continue as Figure 2 As shown, the wireless base station can monitor the communication status of the two hydraulic support controllers in real time, and use heartbeat communication to monitor whether the wireless communication link is abnormal. When the wireless communication link is detected to be abnormal, the wireless communication link is disconnected and the support action of the hydraulic support controller is disconnected to ensure control safety.

[0053] Optionally, a heartbeat signal can be used to monitor whether the wireless communication link is abnormal. The heartbeat signal is a method of sending a very small data packet to the other party of the interconnection at regular intervals (fixed time) to determine whether the communication link between the two parties of the interconnection has been disconnected based on the other party's reply.

[0054] The hydraulic support control system provided in the embodiment of the present application can automatically open the wireless communication link when the wired link fails, so as to realize communication between the hydraulic support controller racks, and can actively report the wired link failure information to realize the support controller link failure detection. At the same time, the reliability of the wireless communication link is monitored through heartbeat communication. When the wireless communication link is abnormal, the wireless communication link will be automatically disconnected, so as to reduce the risk of loss of control of the action due to unstable wireless signals and ensure the safety and reliability of the hydraulic support control.

[0055] In some embodiments, the system 1000 is further used to: number each hydraulic support according to the arrangement sequence of the hydraulic supports to obtain the numbering result of the hydraulic supports.

[0056] In some embodiments, system 1000 is also used to: obtain the first hydraulic support controller that is currently connected to the handheld terminal, determine the next second hydraulic support controller to be connected to the handheld terminal based on the relative distance between the first hydraulic support controller and the handheld terminal, and send a wireless communication module activation instruction from the first hydraulic support controller to the second hydraulic support controller. Through the wireless communication module activation instruction, the wireless communication module corresponding to the second hydraulic support controller is converted from a dormant state to an activated state, and the handheld terminal establishes a connection with the second hydraulic support controller, wherein the wireless communication module corresponding to the first hydraulic support controller is converted from an activated state to a dormant state.

[0057] It should be noted that when the relevant personnel carry the handheld terminal to establish a connection with the hydraulic support controller, the hydraulic support controller will report the support number where the handheld terminal is located to the wireless base station, and then obtain the first hydraulic support controller currently connected to the handheld terminal.

[0058] Optionally, the wireless positioning technology can be used to measure the relative distance between the wireless base station and the handheld terminal. When the handheld terminal moves, the wireless base station determines the bracket number where the handheld terminal is located based on the changed distance, and notifies the next hydraulic support controller through the first hydraulic support controller connected last time by wired communication. The wireless communication module of the next hydraulic support controller is converted from a dormant state to an active state (the corresponding wireless communication module is turned on), and a wireless communication connection is established with the handheld terminal. The wireless communication module corresponding to the originally connected hydraulic support controller is converted from an active state to a dormant state (the corresponding wireless communication module is turned off).

[0059] Furthermore, the hydraulic support controller reports the hydraulic support status and information to the wireless base station, realizing automatic switching between personnel positioning perception and support remote control.

[0060] The hydraulic support control system provided in the embodiment of the present application can determine the position through two kinds of information, the hydraulic support number and the relative distance, and can realize automatic switching of the connected hydraulic support controller after the handheld terminal is connected once.

[0061] The hydraulic support control system proposed in this application is explained below.

[0062] For example, Figure 3As shown, the hydraulic support control system 1000 includes a hydraulic support controller 101, a wireless base station 102, a power box 103, an isolation coupler 104 and a handheld terminal 105. The hydraulic support controllers are connected in series. A wireless base station can be configured for every 6 or 8 hydraulic support controllers, and a power box and an isolation coupler can be configured for every 10 hydraulic support controllers. Each wireless base station includes multiple wireless communication modules, and each hydraulic support controller is configured with a wireless communication module.

[0063] Remote control of the hydraulic support can be achieved: when the hydraulic support control system is powered on, the wireless communication modules of all hydraulic support controllers are in a closed state to minimize the power consumption of the equipment itself. When relevant personnel carry a handheld terminal to establish a connection with the hydraulic support controller, the wireless communication module of the connected hydraulic support controller is activated. Only the connected hydraulic support control wireless communication module communicates with the handheld terminal and reports the information to the wireless base station. The wireless base station registers the status of the wireless communication module and the hydraulic support controller, and other wireless communication modules remain closed.

[0064] Redundant link communication and wired link fault diagnosis can be achieved: when the wired link between adjacent hydraulic support controllers fails, the hydraulic support controllers automatically turn on their respective wireless communication modules and establish a "point-to-point" connection. At the same time, the adjacent hydraulic support controllers simultaneously report their respective status and fault information to the wireless base station. The wireless base station monitors the communication status of the two hydraulic support controllers in real time, and uses heartbeat communication to maintain reliability monitoring of this wireless communication link. If the heartbeat is abnormal, the wireless communication link is automatically disconnected to ensure the safety and reliability of the hydraulic support control.

[0065] It can realize the relative position perception and positioning of relevant personnel and equipment, as well as automatic control switching between handheld terminals and hydraulic support controllers: when the relevant personnel carry the handheld terminal to establish a connection with the first hydraulic support controller, the hydraulic support controller reports the bracket number where the handheld terminal is located to the wireless base station. Using wireless positioning technology, the wireless base station measures the relative distance to the handheld terminal. When the handheld terminal moves, the wireless base station determines the bracket number where the handheld terminal is located based on the changed distance, and notifies the next hydraulic support controller through the last connected hydraulic support controller by wired communication. The next hydraulic support controller turns on the wireless communication module to establish a connection with the handheld terminal, and the originally connected hydraulic support controller turns off the wireless communication module. The currently connected hydraulic support controller reports the bracket status and information to the wireless base station, realizing personnel positioning perception and automatic switching of bracket remote control.

[0066] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this application can be executed in parallel, sequentially or in different orders, as long as the expected results of the technical solution disclosed in this application can be achieved, and this document is not limited here.

[0067] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
