[0024] 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.

[0025] Figure 1 This is one of the structural schematic diagrams of the pressure support controller monitoring system provided by the present invention.

[0026] As shown in FIG. 1 , a hydraulic support controller monitoring system 100 provided in an embodiment of the present invention includes: a hydraulic support controller 101 and a human-machine interface device 102 .

[0027] A hydraulic support controller is used to collect first functional interface performance information of multiple sensors connected to it and second functional interface performance information of at least one adjacent hydraulic support controller connected to it, and send the first functional interface performance information and the second functional interface performance information to a human-machine interface device, wherein the first functional interface performance information at least includes a sensor data set composed of sensor data of multiple sensors, and the second functional interface performance information at least includes communication link status information between the hydraulic support controller and at least one adjacent hydraulic support controller.

[0028] In one embodiment of the present invention, the hydraulic support electro-hydraulic control system is the most critical system for supporting coal mining in a fully mechanized mining face of a coal mine, and the hydraulic support controller is the most critical device in the control system. In the hydraulic support electro-hydraulic control system, many sensors are connected to each hydraulic support controller, and these sensor devices can be used to monitor the system status of the hydraulic support and the fully mechanized mining face. The above sensors will exchange data with the hydraulic support controller through wired communication [such as CAN bus, RS485 bus (signal line A and signal line B), RS232 bus (RX and TX), RS422 bus (signal line A and signal line B) and analog communication]. These sensors may include pressure sensors, position sensors, temperature sensors, etc., which are used to monitor the working status of the hydraulic support. The first functional interface performance information refers to the interface performance information between the hydraulic support controller and the multiple sensors connected to it. The first functional interface performance information at least includes a sensor data set composed of sensor data collected by multiple sensors, and the sensor data in the sensor data set can be used to evaluate the performance and status of the hydraulic support. Among them, the hydraulic support controller is connected to the sensor through, for example, a 4PIN interface, and the main control chip on the hydraulic support controller receives the sensor data of multiple sensors. The second functional interface performance information refers to the interface performance information between the hydraulic support controller and at least one adjacent hydraulic support controller connected to it by wired communication (CAN bus, 100M Ethernet, Gigabit Ethernet or TSN network, etc.) or wireless communication (5G network). This connection usually adopts a "hand-in-hand" method, that is, each hydraulic support controller is not only connected to multiple sensors, but also connected to adjacent hydraulic support controllers. The second functional interface performance information includes the communication link status information between the hydraulic support controller and at least one adjacent hydraulic support controller. Among them, the communication link status information refers to whether the communication link between the hydraulic support controller and the adjacent hydraulic support controller is unobstructed, whether the data transmission is normal, etc. After receiving the first functional interface performance information and the second functional interface performance information, the hydraulic support controller will send it to the human-machine interface device through the core processor on the hydraulic support controller.

[0029] Specifically, when the hydraulic support controller is working, it continuously collects the first functional interface performance information of multiple sensors connected to it and the second functional interface performance information of at least one adjacent hydraulic support controller connected to it, and sends the first functional interface performance information and the second functional interface performance information to the human-machine interface device.

[0030] The human-machine interface device is connected to the hydraulic support controller in communication, and is used to analyze the operating state of the hydraulic support controller based on the received first functional interface performance information and second functional interface performance information, and monitor and control the hydraulic support controller according to the analysis result.

[0031] In one embodiment of the invention, the human-machine interface device is connected to the hydraulic support controller via wired communication (CAN bus, RS485 bus or RS232 bus, etc.). After receiving the first functional interface performance information and the second functional interface performance information sent by the hydraulic support controller, the human-machine interface device can analyze the operating status of the hydraulic support controller using the first functional interface performance information and the second functional interface performance information, and perform corresponding monitoring and control operations based on the analysis results. For example, if the sensor data analysis shows that the operating parameters of a certain hydraulic support deviate from the normal range, the operator is prompted to take necessary maintenance measures. Similarly, if the communication link status analysis reveals that the link is interrupted, the maintenance personnel can be guided to repair it.

[0032] Exemplarily, the hydraulic support controller may also supply power to the human-machine interface device through wired communication.

[0033] In summary, according to the technical solution provided by the embodiment of the present invention, the hydraulic support controller collects the first functional interface performance information from multiple sensors connected to it, and the second functional interface performance information of at least one adjacent hydraulic support controller connected to it, and uses the human-machine interface device connected to the hydraulic support controller to analyze and control the operating status of the hydraulic support controller according to the received first functional interface performance information and second functional interface performance information, so that the fault of the hydraulic support controller can be discovered in time and the hydraulic support controller can be controlled, thereby realizing the monitoring of a single hydraulic support controller, reducing the downtime of the entire hydraulic support control system caused by the failure of a single controller, and enhancing the reliability of the system.

[0034] Figure 2 This is one of the structural schematic diagrams of the human-machine interface device provided by the present invention. Figure 2 As shown, the human-machine interface device 102 includes a state monitoring module 1021 and a main control module 1022 .

[0035] The status monitoring module 1021 is used to determine whether at least one sensor data in the sensor data set exceeds a preset first threshold based on the received sensor data set. When at least one sensor data exceeds the first threshold, it is confirmed that the sensor corresponding to the sensor data exceeding the first threshold is abnormal, triggering a first warning information, and sending the first warning information to the main control module.

[0036] Specifically, the first threshold is a manually preset value used to determine whether the sensor data is abnormal. The first warning information can be a signal or a message used to alert the operator or the system. The state monitoring module is used to receive a sensor data set from the hydraulic controller, and compare the sensor data in the received sensor data set with a preset first threshold. When at least one sensor data in the sensor data set exceeds the first threshold, it is considered that the sensor corresponding to the sensor data exceeding the first threshold is abnormal. Then the state monitoring module triggers the first warning information and sends the first warning information to the main control module.

[0037] The main control module 1022 is used to issue a first control instruction to the hydraulic support controller based on the received first warning information, so that the hydraulic support controller performs a safety function based on the first control instruction; and / or, is used to send the received first warning information to the hydraulic support controller, so that the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can recognize and respond to the first warning information.

[0038] Specifically, after receiving the first warning information sent by the status monitoring module, the main control module can parse the first warning information, and then send the corresponding first control instruction to the hydraulic support controller according to the parsing result, so that the hydraulic support controller performs the safety function according to the first control instruction. The main control module can also choose to send the first warning information directly to the hydraulic support controller, and the hydraulic support controller sends the first warning information to the centralized control host. Through the centralized control host, the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can identify the first warning information and take corresponding response measures according to the first warning information. According to the needs of the specific application, the main control module can also perform the above two operations at the same time.

[0039] Furthermore, the safety function executed by the hydraulic support controller upon receiving the first control instruction can be defined by the operator to adapt to different operation requirements and safety strategies.

[0040] Exemplarily, the main control module of the human-machine interface device is responsible for receiving data from different sensor communication interfaces, including RS485, RS232, RS422, CAN bus, and analog data. Once the main control module receives the data, it will package the data and then transmit it to the state monitoring module 1021. The state monitoring module 1021 integrates and analyzes the sensor data from the sensor group and monitors the changes in the data of different sensors over time. If the analysis finds that the data of any sensor exceeds the preset safety threshold, the state monitoring module 1021 will activate the functional fault warning analysis function. In this case, the state monitoring module 1021 will send a fault warning message to the main control module, and the main control module will send a first control instruction based on the first warning message, and the hydraulic support controller will perform the safety function according to the first control instruction. This process ensures that the system can promptly identify and respond to potential sensor failures or abnormal conditions, thereby maintaining the stability and reliability of the hydraulic support controller and its sensor network.

[0041] In summary, according to the technical solution provided by the embodiment of the present invention, the state monitoring module 1021 in the human-machine interface device 102 monitors the sensor data in real time, and once the data exceeds the preset threshold, an early warning is triggered, and the early warning information is sent to the main control module 1022, which then issues a control instruction to the hydraulic support controller, thereby quickly responding to abnormal situations, ensuring personnel safety and system stability, and effectively realizing real-time monitoring of the hydraulic support controller. Furthermore, the main control module can also send the early warning information to the hydraulic support controller, which is sent to the centralized control host by the hydraulic support controller, so that the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can clearly understand the early warning information and make corresponding responses according to the early warning information.

[0042] Figure 3 This is the second structural schematic diagram of the human-machine interface device provided by the present invention. Figure 3 As shown, the human-machine interface device 102 further includes a display module 1023 .

[0043] Specifically, the display module 103 may be a computer screen, a console display, or other types of visualization devices.

[0044] Furthermore, the state monitoring module 1021 is further configured to send a first comparison result between the sensing data in the sensing data set and the first threshold to the main control module 1022 .

[0045] Specifically, the state monitoring module 1021 compares each data point in the received sensor data set with a preset first threshold. The comparison result may be that the sensor data does not exceed the first threshold, that is, everything is normal; or, the sensor data exceeds the first threshold, indicating that there is an abnormality. Regardless of the comparison result, the state monitoring module 1021 will send the first comparison results including the sensor data and the first threshold to the main control module 1022.

[0046] Furthermore, the main control module 1022 is used to convert the received first comparison result into a chart form and send it to the display module 103 for display.

[0047] Specifically, after receiving the first comparison result, the main control module 1022 converts the first comparison result into a chart form according to the received first comparison result (including the comparison data of the sensor data and the first threshold value). This conversion helps to understand the data more intuitively, so that the operator can quickly identify trends, anomalies and key performance indicators. Exemplarily, the conversion into a chart form can include various types of charts, such as line charts, bar charts, pie charts, etc., depending on the type of data and purpose to be displayed. For example, a line chart can be used to show the trend of sensor data over time, and a bar chart can be used to compare data values ​​of different sensors. The converted chart data is sent to the display module 103 for display. The operator can view the chart through the display module 103 to better understand the operating status of the system, and make decisions or take actions based on the information provided by the chart. By visualizing the data, the main control module 1022 enhances the interactivity of the system and the decision-making ability of the user, so that the operator can identify and respond to potential problems more intuitively and quickly.

[0048] In summary, according to the technical solution provided in the embodiment of the present invention, the status monitoring module 1021 in the human-machine interface device 102 monitors the sensor data in real time and compares it with the preset threshold value, and sends the comparison result to the main control module 1022, which converts the data into an intuitive graphical form and displays it to the operator through the display module 103, thereby improving the visualization of the system operation status, enhancing the operator's ability to quickly identify system performance and abnormalities, improving decision-making efficiency and system response speed, and better realizing real-time monitoring of the hydraulic support controller.

[0049] Furthermore, the communication link status information includes communication bandwidth, communication delay, communication bit error rate and anti-interference quantization value.

[0050] Specifically, the communication bandwidth refers to the ability of the communication link to transmit data in a unit time. The network test tools on both sides of the hydraulic support controller can be used to measure the actual data transmission rate. The network test tools on both sides of the hydraulic support controller can be used to measure the actual data transmission rate, and the measured communication bandwidth can be sent to the hydraulic support controller. The communication delay data refers to the total time from the sender to the receiver and then from the receiver back to the sender, which is used to judge the delay of the communication link. Based on the round-trip time (RTT) measurement method, the network detection Ping delay detection tool is used to obtain the communication delay. Specifically, the difference between the timestamps from the data sent to the data received is the RTT. The communication bit error rate is used to judge the data transmission integrity of the communication link. Under the premise that the hydraulic support controller is fault-free, the normal communication link is CRC check (cyclic redundancy check). Based on the CRC check result, it can be judged whether the data is damaged during the transmission process. And obtain the ratio between the data bits received incorrectly during the transmission process and the total data bits received, that is, the communication bit error rate. Anti-interference refers to the ability of the communication link to maintain stable data transmission when facing external interference such as electromagnetic interference. The ratio of the signal to the background noise can be measured on both sides of the hydraulic support controller. A high signal-to-noise ratio (SNR) indicates that the communication link has better anti-interference performance. The anti-interference performance is quantified as an anti-interference quantification value as one of the communication link status information.

[0051] Exemplarily, the performance indicators such as bandwidth, delay, bit error rate, anti-interference, etc. of each communication link can also be obtained in real time through methods such as heartbeat detection, error rate detection and delay detection.

[0052] Furthermore, the status monitoring module 1021 is also used to: determine whether there is an abnormality in the communication link between the hydraulic support controller and the adjacent hydraulic support based on the received communication bandwidth, communication delay, communication bit error rate and anti-interference quantified value; when it is confirmed that there is an abnormality, send a second warning information to the main control module.

[0053] Specifically, the status monitoring module 1021 analyzes whether there is an abnormality in the communication link between the hydraulic support control and the adjacent hydraulic support control based on the collected communication link status information, including communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative value.

[0054] In practical applications, the actual measured values ​​of the communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative values ​​are compared with the preset normal operating parameter range. When any one or more of the above communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative values ​​exceed the normal range, the status monitoring module 1021 confirms that the communication link is abnormal. Once the communication link is confirmed to be abnormal, the status monitoring module 1021 will send a second warning message to the main control module 1022. The second warning message may include the type, degree and possible impact of the abnormality. Exemplarily, if the communication bandwidth is lower than the expected value, it may indicate that the link is overloaded or there is a bottleneck. If the communication delay (RTT) increases significantly, it may mean that the link is congested or there are other delay problems. If the communication bit error rate increases, it may indicate signal interference or link quality problems. If the anti-interference quantitative value is lower than the threshold, it may mean that the link is susceptible to external interference.

[0055] Furthermore, the main control module 1022 is also used to issue a second control instruction to the hydraulic support controller based on the received second warning information, so that the hydraulic support controller performs a safety function based on the second control instruction; and / or, to send the received second warning information to the hydraulic support controller, so that the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can recognize and respond to the second warning information.

[0056] Specifically, after receiving the second warning information, the main control module 1022 can parse the second warning information, and then send the corresponding second control instruction to the hydraulic support controller according to the analysis result, so that the hydraulic support controller performs the safety function according to the second control instruction. The main control module can also choose to send the second warning information directly to the hydraulic support controller, and the hydraulic support controller sends the second warning information to the centralized control host. Through the centralized control host, the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can identify the second warning information and take corresponding response measures according to the second warning information. According to the needs of the specific application, the main control module can also perform the above two operations at the same time.

[0057] Furthermore, the safety function executed by the hydraulic support controller upon receiving the second control instruction can be defined by the operator to adapt to different operation requirements and safety strategies.

[0058] For example, the state monitoring module 1021 may receive the communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative value transmitted by the hydraulic support controller at a certain frequency, and record the change curve of the communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative value over time, and calculate the change rate of the communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative value over time according to the change curve. According to the change rate, the state monitoring module 1021 can determine whether there is an abnormality in the communication link. For example, if the change rate of the communication bandwidth suddenly increases, it may indicate that the link is overloaded; if the change rate of the communication delay continues to increase, it may mean that the link is congested or there are other delay problems. Once an abnormality is detected, the state monitoring module 1021 will send a second warning message to the main control module according to the preset threshold and analysis results, and the main control module will send a second control instruction according to the second warning message, and the hydraulic support controller will execute the safety function according to the second control instruction.

[0059] Exemplarily, the state monitoring module 1021 may receive the communication bandwidth, communication delay, communication bit error rate and anti-interference quantified values ​​transmitted by the hydraulic support controller, and quantify the communication bandwidth, communication delay, communication bit error rate and anti-interference quantified values ​​into Y1, Y2, Y3 and Y4 respectively. The corresponding weight factors are set to t1, t2, t3 and t4 respectively. Then the performance score of the communication link can be obtained as U=t1Y1+t2Y2+t3Y3+t4Y4. According to the comparison between the calculated performance score U and the preset performance score threshold, if U is lower than the threshold, it can be considered that the communication link is abnormal. Among them, the weight factor generally involves an evaluation of the importance of each parameter on the performance of the communication link, which can be achieved through the techniques such as expert experience, historical data analysis, hierarchical analysis method, information entropy method, grey correlation analysis or data-driven method to ensure that the weight distribution can accurately reflect the actual role and importance of each parameter in the performance of the communication link. It can be determined specifically according to the actual application scenario.

[0060] In summary, according to the technical solution provided by the embodiment of the present invention, the status monitoring module 1021 can monitor the status of the communication link in real time, and notify the main control module in time when an abnormality is detected, so as to take necessary safety measures to prevent possible communication failures from affecting the normal operation of the hydraulic support controller, thereby reducing production losses; this monitoring and early warning mechanism is necessary to ensure the stable operation of the hydraulic support controller. Furthermore, the main control module can send the early warning information to the hydraulic support controller, which is sent to the centralized control host by the hydraulic support controller, so that the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can clearly understand the early warning information and make corresponding responses according to the early warning information.

[0061] The status monitoring module 1021 is also used to obtain the change information of the communication bandwidth, communication delay, communication bit error rate and anti-interference quantization value over time based on the received communication bandwidth, communication delay, communication bit error rate and anti-interference quantization value, and send the change information to the main control module 1022.

[0062] Specifically, the status monitoring module 1021 receives the communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative value transmitted by the hydraulic support controller at a certain frequency, and obtains the change information of the communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative value over time, such as the change rate or the change curve, and sends the change information of the communication bandwidth, communication delay, communication bit error rate and anti-interference quantitative value to the main control module 1022.

[0063] The main control module 1022 is also used to convert the received change information into a chart form and send it to the display module for display.

[0064] Specifically, after receiving the change information of the signal bandwidth, communication delay, communication bit error rate and anti-interference quantitative value, the main control module 1022 converts each change information into a chart form. This conversion helps to understand the data more intuitively, so that the operator can quickly identify trends, anomalies and key performance indicators. Exemplarily, the chart can include various types of charts, such as line charts, bar charts, pie charts, etc., depending on the type of data and purpose to be displayed. The converted chart is sent to the display module 103 for display. The operator can view the chart through the display module 103 to better understand the operating status of the system, and make decisions or take actions based on the information provided by the chart. By visualizing the data, the main control module 1022 enhances the interactivity of the system and the decision-making ability of the user, so that the operator can identify and respond to potential problems more intuitively and quickly.

[0065] Furthermore, the first functional interface performance information also includes first power supply function information.

[0066] Specifically, the first power supply function information may refer to parameters related to the power supply status of the functional interface of the hydraulic support controller connected to multiple sensors through wired communication, such as voltage and current information. The hydraulic support controller has the ability to monitor the voltage and current information of the power supply interface. It can monitor the power consumption data of the sensor connected to the functional interface in real time through the voltage and current detection chip, and then determine whether the power supply status of the functional interface connecting the hydraulic support controller and the sensor is normal.

[0067] Furthermore, the status monitoring module 1021 is also used to confirm whether there is an abnormality in the power supply status of the functional interface between the hydraulic support controller and multiple sensors based on the first power supply function information; when it is determined that there is an abnormality, send a third warning information to the main control module.

[0068] Specifically, the third warning information is a warning signal sent by the state monitoring module 1021 to the main control module when the power supply state between the hydraulic support controller and the sensor is detected to be abnormal, and contains key information such as the abnormality type, degree, and timestamp. After receiving the first power supply function information sent by the hydraulic support, the state monitoring module 1021 can determine whether there is an abnormality in the power supply state of the functional interface between the hydraulic support controller and the multiple sensors connected to it by analyzing the first power supply function information. When it is determined that there is an abnormality, the state monitoring module will generate the third warning information and send the third warning information to the main control module 1022.

[0069] Furthermore, the main control module 1022 is also used to send a third control instruction to the hydraulic support controller based on the received third warning information, so that the hydraulic support controller performs a safety function based on the third control instruction; and / or, to send the received third warning information to the hydraulic support controller, so that the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can recognize and respond to the third warning information.

[0070] Specifically, after receiving the third warning information, the main control module 1022 will generate a third control instruction according to the third warning information, and send the third control instruction to the hydraulic support controller. After receiving the third control instruction, the hydraulic support controller will execute the corresponding safety function. The main control module can also choose to send the third warning information directly to the hydraulic support controller, and the hydraulic support controller sends the third warning information to the centralized control host. Through the centralized control host, the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can identify the third warning information and take corresponding response measures according to the third warning information. According to the needs of the specific application, the main control module can also perform the above two operations at the same time.

[0071] Furthermore, the safety function executed by the hydraulic support controller upon receiving the third control instruction can be defined by the operator to adapt to different operation requirements and safety strategies.

[0072] Exemplarily, the state monitoring module 1021 of the human-machine interface device receives the voltage and current data of the functional interface between the hydraulic support controller and the sensor transmitted by the hydraulic support controller at a certain frequency, and sets the voltage threshold and current threshold according to different sensor types. The voltage threshold and current threshold are predetermined based on the technical parameters and safety requirements of the sensor. Under the premise that the sensor is connected, if the voltage and current data of the functional interface exceed the threshold, it is determined that the power supply state of the functional interface corresponding to the voltage and current data is abnormal or the sensor itself is abnormal. At this time, the state monitoring module will generate a third warning information and send the third warning information to the main control module. The main control module sends a third control instruction according to the third warning information, and the hydraulic support controller executes the safety function according to the third control instruction.

[0073] In summary, according to the technical solution provided in the embodiment of the present invention, the power supply security of the hydraulic support controller and its sensors is effectively maintained through real-time monitoring, intelligent analysis and rapid response, ensuring the stability of the entire system and the safety of operators.

[0074] Furthermore, the second functional interface performance information also includes second power supply function information.

[0075] Specifically, the second power supply function information refers to parameters related to the power supply state of the functional interface connecting the hydraulic support controller and at least one adjacent hydraulic support controller, such as voltage and current.

[0076] The status monitoring module is also used to determine whether there is an abnormality in the power supply interface between the hydraulic support controller and the adjacent hydraulic support based on the second power supply function information; when it is determined that there is an abnormality, send a fourth warning information to the main control module.

[0077] Specifically, the status monitoring module is responsible for monitoring and analyzing the second power supply function information to determine whether the power supply interface between the hydraulic support controller and the adjacent hydraulic support is normal. Exemplarily, the status monitoring module determines whether there is an abnormality in the power supply interface by analyzing the second power supply function information, such as whether the voltage and current are within the normal range. If the monitoring result shows that there is an abnormality in the power supply interface, the status monitoring module will generate a fourth warning message and send this information to the main control module. The fourth warning message is used to alert the main control module so that it can respond to the abnormality of the power supply interface between the hydraulic support controller and the adjacent hydraulic support in a timely manner and take measures to ensure the safety and stability of the system.

[0078] Furthermore, the main control module is also used to send a fourth control instruction to the hydraulic support controller based on the received fourth warning information, so that the hydraulic support controller performs a safety function based on the fourth control instruction; and / or, is used to send the received fourth warning information to the hydraulic support controller, so that the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can recognize and respond to the fourth warning information.

[0079] Specifically, after receiving the fourth warning information, the main control module will send the fourth control instruction to the hydraulic support controller according to the content of the warning information. After receiving the fourth control instruction, the hydraulic support controller will execute the safety function, thereby ensuring that it can respond quickly in the case of abnormal power supply, effectively preventing equipment damage and safety accidents, and ensuring the safety and stable operation of the entire hydraulic support system using the hydraulic support controller. The main control module can also choose to send the fourth warning information directly to the hydraulic support controller, and the hydraulic support controller will send the fourth warning information to the centralized control host. Through the centralized control host, the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can identify the fourth warning information and take corresponding response measures according to the fourth warning information. According to the needs of the specific application, the main control module can also perform the above two operations at the same time.

[0080] Furthermore, the safety function executed by the hydraulic support controller upon receiving the fourth control instruction may be defined by the operator to adapt to different operation requirements and safety strategies.

[0081] In summary, according to the technical solution provided by the embodiment of the present invention, the power supply interface between the hydraulic support controller and its adjacent hydraulic support controllers is monitored in real time through the status monitoring module. Once it is detected that the power supply parameters such as voltage or current exceed the preset threshold, the fourth warning information is triggered and sent to the main control module. The main control module then issues a fourth control instruction based on the warning information to instruct the hydraulic support controller to perform the safety function, thereby ensuring a rapid response in the event of abnormal power supply, effectively preventing equipment damage and safety accidents, and ensuring the safety and stable operation of the entire hydraulic support system using the hydraulic support controller. Furthermore, the main control module can also send the warning information to the hydraulic support controller, which is sent by the hydraulic support controller to the centralized control host, so that the hydraulic support electro-hydraulic control system where the hydraulic support controller is located can clearly understand the warning information and make corresponding responses based on the warning information.

[0082] Furthermore, the button module is used to receive an input command, and based on the input command, enable the status monitoring module to receive the first function interface performance information and the second function interface performance information.

[0083] Specifically, the key module is used to receive input commands from operators, which may be in the form of physical keys or virtual keys on a touch screen. The state monitoring module receives the first function interface performance information and the second function interface performance information from the hydraulic support controller according to the input instruction of the key module.

[0084] In summary, the above design allows operators to control the data collection and monitoring process through simple input commands, which improves the interactivity and convenience of the system, and also makes the monitoring of the hydraulic support controller more flexible and timely.

[0085] To describe in detail the human-machine interface device provided by the embodiment of the present invention, refer to the attached Figure 4 , Figure 4 This is the third structural schematic diagram of the human-machine interface device provided by the present invention.

[0086] like Figure 4 As shown, the human-machine interface device 400 includes a state monitoring module 401 , a main control module 402 , a display module 403 , a control state indication module 404 , a button module 405 , a power supply module 406 , a communication module 407 and a power supply and communication interface 408 .

[0087] The power supply and communication interface 408 is mainly used to connect to the hydraulic support controller via a cable.

[0088] The power supply and communication interface 408 is used to supply power to the power supply module 406 and to exchange data with the communication module 407 .

[0089] Furthermore, the power supply module 406 supplies power to the main control module 402 , the communication module 407 , the button module 405 , the state monitoring module 401 , the control state indicating module 404 and the display module 403 respectively.

[0090] Furthermore, the main control module 402 performs two-way data communication with the communication module 407, the state monitoring module 401, the key module 405 and the display module 403. The main control module 402 outputs control instructions to the control state indication module. The main control module 402 receives data transmitted by the power supply module 406.

[0091] Specifically, the power supply module 406 is responsible for voltage conversion, supplying power to other modules and transmitting power supply information (including input voltage, current and output voltage, current information) of the human-machine interface device to the main control module.

[0092] During use of the hydraulic support controller monitoring system, the human-machine interface device receives the first functional interface performance information and the second functional interface performance information from the hydraulic support controller via the power supply and communication interface 408, and the power supply and communication interface 408 sends the first functional interface performance information and the second functional interface performance information to the status monitoring module 401 via the communication module 407 and the main control module 402.

[0093] Further, see Figure 5 , Figure 5 This is one of the structural diagrams of the status monitoring module provided by the present invention.

[0094] like Figure 5 As shown, the state monitoring module 401 includes a sensor group state monitoring module 4011 and a hydraulic support controller state monitoring module 4012 .

[0095] Specifically, the sensor group state monitoring module 4011 is used to obtain the first functional interface performance information, and the hydraulic support controller state monitoring module 4012 is used to obtain the second functional interface performance information.

[0096] By analyzing the first functional interface performance information through the sensor group status monitoring module 4011 of the human-machine interface device and the second functional interface performance information through the hydraulic support controller status monitoring module 4012, the operating status of the hydraulic support controller is analyzed, and the hydraulic support controller is monitored and controlled based on the analysis results.

[0097] Furthermore, the sensor group status monitoring module 4011 and the hydraulic support controller status monitoring module 4012 both have a fault warning function.

[0098] Specifically, the first warning information and the third warning information are sent by the sensor group state monitoring module 4011 to the main control module 402 and / or the hydraulic support controller.

[0099] Specifically, the second warning information and the fourth warning information are sent by the hydraulic support controller state monitoring module 4012 to the main control module and / or the hydraulic support controller.

[0100] Specifically, the first control instruction, the second control instruction, the third control instruction and the fourth control instruction are sent by the main control module 402 to the hydraulic support controller through the communication module 407 and the power supply and communication interface module 408 .

[0101] Specifically, the button module is used to receive input commands from the operator. Through the input commands, the control main control module 402 receives the first functional interface performance information and the second functional interface performance information from the hydraulic support control through the communication module 407 and the power supply and communication interface module 40.

[0102] Specifically, the display module 403 is used to receive chart information from the main control module for display.

[0103] Specifically, the control status indication module 404 is used to display the working status of the human-machine interface device.

[0104] Figure 6 It is a system architecture diagram of the hydraulic support electro-hydraulic control system provided by the present invention.

[0105] like Figure 6 As shown, the hydraulic support electro-hydraulic control system includes multiple sets of sensors (i.e. Figure 6 Multiple sensor groups as shown) and multiple hydraulic support controller monitoring systems as mentioned above, each sensor group is connected to a hydraulic support controller monitoring system.

[0106] Specifically, all hydraulic supports in the fully mechanized mining face have their own numbers, and the numbers of adjacent hydraulic supports are increased or decreased in sequence. A hydraulic support controller is installed on each hydraulic support, and the hydraulic support controllers are connected hand in hand for power supply and wired communication. Each hydraulic support controller is connected to a human-machine interface device to form a hydraulic support controller monitoring system. Among them, each hydraulic support controller monitoring system is connected to a group of sensors (i.e. Figure 6 sensor group shown).

[0107] In summary, according to the technical solution provided in the embodiment of the present invention, there are multiple hydraulic support controller monitoring systems in the hydraulic support electro-hydraulic control system, which can monitor and control each hydraulic support controller in the hydraulic support electro-hydraulic control system, reduce the occurrence of faults, ensure operation safety and efficiency, and enhance the stability and reliability of the entire hydraulic support electro-hydraulic control system.

[0108] Figure 7 It is a flow chart of the hydraulic support controller monitoring method provided by the present invention.

[0109] like Figure 7 As shown, the hydraulic support controller monitoring method specifically includes the following steps: Step 701: Use a hydraulic support controller to collect first functional interface performance information of multiple sensors connected to it and second functional interface performance information of at least one adjacent hydraulic support controller connected to it, and send the first functional interface performance information and the second functional interface performance information to a human-machine interface device, wherein the first functional interface performance information at least includes a sensor data set composed of sensor data of multiple sensors, and the second functional interface performance information at least includes communication link status information between the hydraulic support controller and at least one adjacent hydraulic support controller.

[0110] Step 702: Analyze the operating status of the hydraulic support controller based on the received first functional interface performance information and second functional interface performance information using the human-machine interface device, and monitor and control the hydraulic support controller according to the analysis result.

[0111] Specifically, the hydraulic support electro-hydraulic control system is the most critical system to support coal mining in the fully mechanized mining face of a coal mine, and the hydraulic support controller is the most critical equipment in the control system. In the hydraulic support electro-hydraulic control system, many sensors will be connected to each hydraulic support controller, and these sensor devices can be used to monitor the system status of the hydraulic support and the fully mechanized mining face. The above sensors will exchange data with the hydraulic support controller through wired communication [such as CAN bus, RS485 bus (signal line A and signal line B), RS232 bus (RX and TX), RS422 bus (signal line A and signal line B) and analog communication]. These sensors may include pressure sensors, position sensors, temperature sensors, etc., which are used to monitor the working status of the hydraulic support. The first functional interface performance information refers to the interface performance information between the hydraulic support controller and the multiple sensors connected to it. The first functional interface performance information includes a sensor data set composed of sensor data collected by multiple sensors, and the sensor data in the sensor data set can be used to evaluate the performance and status of the hydraulic support. Among them, the hydraulic support controller is connected to the sensor through, for example, a 4PIN interface, and the main control chip on the hydraulic support controller receives the sensor data of multiple sensors. The second functional interface performance information refers to the interface performance information between the hydraulic support controller and at least one adjacent hydraulic support controller connected to it by wired communication (CAN bus, 100M Ethernet, Gigabit Ethernet or TSN network, etc.) or wireless communication (5G network). This connection usually adopts a "hand-in-hand" method, that is, each hydraulic support controller is not only connected to multiple sensors, but also connected to adjacent hydraulic support controllers. The second functional interface performance information includes the communication link status information between the hydraulic support controller and at least one adjacent hydraulic support controller. Among them, the communication link status information refers to whether the communication link between the hydraulic support controller and the adjacent hydraulic support controller is unobstructed, whether the data transmission is normal, etc. After receiving the first functional interface performance information and the second functional interface performance information, the hydraulic support controller will send it to the human-machine interface device through the core processor on the hydraulic support controller. Specifically, when the hydraulic support controller is working, it continuously collects the first functional interface performance information of multiple sensors connected to it and the second functional interface performance information of at least one adjacent hydraulic support controller connected to it, and sends the first functional interface performance information and the second functional interface performance information to the human-machine interface device. The human-machine interface device is connected to the hydraulic support controller through wired communication (CAN bus, RS485 bus or RS232 bus, etc.), and is used to analyze the operating state of the hydraulic support controller according to the received first functional interface performance information and second functional interface performance information, and can comprehensively evaluate the operating state of the hydraulic support controller, and perform corresponding monitoring and control operations according to the analysis results.For example, if the sensor data analysis shows that the operating parameters of a hydraulic support deviate from the normal range, the operator is prompted to take necessary maintenance measures. Similarly, if the communication link status analysis reveals that the link is broken, the maintenance personnel can be guided to repair it. Exemplarily, the hydraulic support controller can also power the human-machine interface device through wired communication.

[0112] In summary, according to the technical solution provided by the embodiment of the present invention, the hydraulic support controller collects the first functional interface performance information from multiple sensors connected to it, and the second functional interface performance information of at least one adjacent hydraulic support controller connected to it, and uses the human-machine interface device connected to the hydraulic support controller to analyze and control the operating status of the hydraulic support controller according to the received first functional interface performance information and second functional interface performance information, so that the fault of the hydraulic support controller can be discovered in time and the hydraulic support controller can be controlled, thereby realizing the monitoring of a single hydraulic support controller, reducing the downtime of the entire hydraulic support control system caused by the failure of a single controller, and enhancing the reliability of the system.
