[0048] Figure 3 The flowchart of the steps of the automatic connection method between the remote control and the hydraulic support provided by the present disclosure is shown as follows: Figure 3 As shown, the automatic connection method between the remote control and the hydraulic support includes the following steps:

[0049] S101, obtaining first instruction information, wherein the first instruction information at least includes a control instruction indicating a connection mode.

[0050] In this step, first instruction information is obtained, wherein the first instruction information at least includes a control instruction indicating a connection mode, which is used to indicate a connection mode between the remote controller and the hydraulic support controller.

[0051] Specifically, the first instruction information can be sent by the staff to the remote control through the control end and obtained by the remote control, so that the remote control located on the comprehensive mining working face determines the connection method between the remote control and the hydraulic support controller by obtaining the first instruction information on the server end.

[0052] S102, determining a connection mode of the remote controller based on the first instruction information, where the connection mode includes an automatic connection mode and a manual connection mode.

[0053] After the first instruction information is acquired, in this step, a connection mode of the remote controller is determined based on the first instruction information, and the connection mode includes an automatic connection mode and a manual connection mode.

[0054] Specifically, during the control process of the hydraulic support, the connection method between the controller of the hydraulic support and the remote control includes an automatic connection mode and a manual connection mode; the remote control determines the connection method between the remote control and the controller of the hydraulic support by receiving a first command information from the server side, wherein, when the first command information is automatic connection, the remote control enters the automatic connection mode to control the hydraulic support; when the first command information is manual connection, the remote control enters the manual connection mode to control the hydraulic support.

[0055] S103, determining matching information with the remote controller based on the connection mode, where the matching information is used to indicate a hydraulic support to be matched with the remote controller.

[0056] After completing the above step S102, in this step, the matching information with the remote controller is determined based on the connection mode, wherein the matching information is used to indicate the hydraulic support to be matched with the remote controller.

[0057] Further, Figure 4 The flowchart of the steps of determining the matching information with the remote controller based on the connection mode provided by the present disclosure is shown as follows: Figure 4 As shown, determining the matching information with the remote controller based on the connection mode includes the following steps:

[0058] S201, when the connection mode is the manual connection mode, manually input the code of the hydraulic support to be controlled as matching information.

[0059] In this step, when the connection mode is the manual connection mode, the control personnel manually inputs the code of the hydraulic support to be controlled as matching information based on the control requirements to achieve the communication connection between the hydraulic support and the controller of the hydraulic support to be controlled.

[0060] S202, when the connection mode is the automatic connection mode, determining matching information based on parameter information, the parameter information includes a first signal strength and a second signal strength, the first signal strength is used to characterize the signal strength measured when the Bluetooth device receives the signal; the second signal strength is used to characterize the signal strength of the low-frequency terminal device.

[0061] In this step, when the connection mode is automatic connection mode, the matching information is determined based on parameter information, the parameter information includes a first signal strength and a second signal strength, the first signal strength is used to characterize the signal strength measured when the Bluetooth device receives the signal; the second signal strength is used to characterize the signal strength of the low-frequency terminal device.

[0062] Specifically, Figure 5 The flowchart of the steps of determining matching information based on parameter information provided by the present disclosure is shown as follows: Figure 5 As shown, determining matching information based on parameter information includes the following steps:

[0063] S301, determining a distance test initial mode based on first instruction information, the first instruction information also includes a control instruction indicating the distance test initial mode, and the distance measurement initial mode includes a fusion measurement mode, a Bluetooth measurement mode and a low-frequency measurement mode.

[0064] In this step, the distance test initial mode is determined based on the first instruction information, wherein the first instruction information also includes a control instruction indicating the distance test initial mode, the first instruction information is the control instruction obtained by the remote control from the server, and the distance measurement initial mode includes a fusion measurement mode, a Bluetooth measurement mode and a low-frequency measurement mode, and the fusion measurement mode is a redundant measurement mode of low frequency and Bluetooth.

[0065] S302, determining a distance measurement final mode based on a distance test initial mode.

[0066] After completing the above step S301, in this step, when the initial distance measurement mode is the fusion measurement mode, the final distance measurement mode is determined based on the parameter information, and the final distance measurement mode includes the fusion measurement mode and the Bluetooth measurement mode; when the initial distance measurement mode is the Bluetooth measurement mode or the low-frequency measurement mode, the initial distance measurement mode is used as the final distance measurement mode.

[0067] Further, after the distance test initial mode is determined based on the first instruction information, when the distance test initial mode is the Bluetooth measurement mode, the distance between the remote control and the hydraulic support is measured by Bluetooth measurement, and when the distance measurement initial mode is the low-frequency measurement mode, the distance between the remote control and the hydraulic support is measured by low-frequency measurement. When the distance measurement initial mode is the fusion measurement mode, the distance measurement final mode is determined based on the parameter information.

[0068] Among them, the final distance measurement mode includes a fusion measurement mode and a Bluetooth measurement mode.

[0069] Specifically, in the process of distance measurement, Bluetooth distance measurement or low frequency distance measurement can be generally used for distance measurement. The parameter information includes a first signal strength and a second signal strength. The first signal strength is used to characterize the signal strength measured when the Bluetooth device receives a signal, that is, the received signal strength of the Bluetooth device; the second signal strength is used to characterize the signal strength of the low frequency terminal device.

[0070] Among them, when the first signal strength is lower than the first threshold and the second signal strength is lower than the second threshold, that is, when both the first signal strength and the second signal strength are low, the distance measurement final mode adopts the Bluetooth measurement mode. The first threshold and the second threshold are set by the staff based on the actual situation of the comprehensive mining face, and the first threshold and the second threshold can be the same or different.

[0071] Otherwise, the final distance measurement mode adopts the fusion measurement mode, which is a redundant measurement mode of low frequency and Bluetooth.

[0072] S303: Determine the distance information between the hydraulic support and the remote controller based on the final distance measurement mode.

[0073] After completing the above step S302, in this step, the distance information between the hydraulic support and the remote controller is determined based on the final mode of distance measurement.

[0074] Specifically, in the Bluetooth measurement mode, the distance between the hydraulic support and the remote controller is measured based on the Bluetooth measurement mode, thereby obtaining distance information.

[0075] in,

[0076] In the formula, d1 represents the distance between the remote control and the hydraulic support controller obtained through the Bluetooth measurement mode, in meters; RSSI1 represents the first signal strength, in dBm; A1 represents the reference first signal strength value when the distance between the remote control and the hydraulic support controller is 1 meter; n represents the environmental attenuation factor, which is based on the underground environment setting. Usually, n is between 2 and 4 during Bluetooth ranging, where the open area is close to 2 and the complex environment is 3-4.

[0077] Further, Figure 6 The flowchart of the steps of determining the distance information between the hydraulic support and the remote controller based on the distance measurement final mode provided by the present disclosure is shown as follows: Figure 6 As shown, determining the distance information between the hydraulic support and the remote controller based on the distance measurement final mode includes the following steps:

[0078] S401, in a fusion measurement mode, determining a first distance and a second distance between the hydraulic support and the remote control.

[0079] In this step, the first distance and the second distance between the hydraulic support and the remote control are determined, wherein the first distance is the distance between the hydraulic support and the remote control measured by Bluetooth measurement, and the second distance is the distance between the hydraulic support and the remote control measured by low-frequency measurement.

[0080] Specifically,

[0081] In the formula, d1 represents the distance between the remote control and the hydraulic support controller obtained through the Bluetooth measurement mode, that is, the first distance, in meters, d2 represents the distance between the remote control and the hydraulic support controller obtained through the low-frequency measurement mode, that is, the second distance, in meters, RSSI2 represents the second signal strength, in dBm; A2 represents the reference second signal strength value when the distance between the remote control and the hydraulic support controller is 1 meter.

[0082] S402: Determine first weighted information and second weighted information based on the first distance information and the second distance information.

[0083] After completing the above step S401, in this step, the first weighted information and the second weighted information are determined based on the first distance information and the second distance information, wherein the first weighted information and the second weighted information are respectively weighted coefficients of the first distance and the second distance in the fusion measurement mode, which are used to characterize the proportion of the first distance and the second distance in the distance determination process.

[0084] Specifically, after obtaining the first distance information and the second information, based on the first distance information or the second distance information, the weighted information comparison table is consulted to obtain the first weighted information and the second weighted information, wherein the first weighted information and the second weighted information are pre-calibrated.

[0085] S403: confirm the distance information based on the first distance information, the second distance information, the first weighted information and the second weighted information.

[0086] After completing the above step S402, in this step, the distance information is confirmed based on the first distance information, the second distance information, the first weighted information and the second weighted information. Specifically,

[0087] d = d1 × a1 + d2 × a2;

[0088] Wherein, d is distance information, d1 is first distance information, d2 is second distance information, a1 is first weighted information, and a2 is second weighted information.

[0089] In order to improve the measurement accuracy, in a specific embodiment of the present application, the change rate of the first distance and the second distance is also monitored, so as to avoid the influence of the distance mutation caused by the sudden metal obstacle in the working surface on the measurement accuracy during the measurement process.

[0090] Specifically, when the change rate of the first distance or the change rate of the second distance is greater than a preset threshold, it indicates that the devices may be blocked by a metal obstacle and the distance measurement is disturbed. The weighted information of the disturbed data is set to 0, and the other distance information that is not disturbed is used as the distance information between the hydraulic support and the remote controller.

[0091] For example, if the change rate of d1 exceeds a threshold during the measurement process, a1 is set to zero and a2 is set to 1, so that the second distance information d2 is used as the distance information between the hydraulic support and the remote controller.

[0092] S304: Determine matching information of the hydraulic support based on the distance information.

[0093] After completing the above step S303, in this step, the matching information of the hydraulic support is determined based on the distance information.

[0094] Specifically, after obtaining the distance information between the remote control and the controllers of each hydraulic support, the hydraulic support with the closest distance is selected as the hydraulic support to be connected to the remote control, thereby avoiding the problem of automatic connection jump when the remote control faces two hydraulic support controllers with similar distances and the problem of large environmental interference in the comprehensive mining working face.

[0095] Furthermore, in the automatic mode, the connection switching time between the remote controller and different hydraulic support controllers is set to more than 1 second, thereby avoiding the situation of repeatedly switching the connection flights in a short time.

[0096] S104: Establish a communication connection with a controller of the hydraulic support based on the matching information.

[0097] After completing the above step S103, in this step, a communication connection is established with the controller of the hydraulic support based on the matching information.

[0098] Specifically, after the matching information is determined, the remote controller automatically establishes a communication connection with the hydraulic support based on the matching information. Figure 7 The flowchart of the steps of establishing a communication connection with a hydraulic support based on matching information provided by the present disclosure is shown as follows Figure 7 As shown, establishing a communication connection with the hydraulic support based on the matching information includes the following steps:

[0099] S501, acquiring communication information based on matching information, where the communication information includes second instruction information and signal strength information.

[0100] In this step, communication information is obtained based on the matching information, and the communication information includes the second instruction information and the signal strength information. The second instruction information can be sent by the staff to the remote controller through the control terminal and obtained by the remote controller, so that the remote controller located on the fully mechanized mining working face determines the communication mode between the remote controller and the hydraulic support controller by obtaining the second instruction information on the server side.

[0101] S502: Determine a final communication mode based on the communication information.

[0102] After completing the above step S501, in this step, the final communication mode is determined based on the communication information.

[0103] Specifically, Figure 8 The flowchart of the steps of determining the final communication mode based on the communication information provided by the present disclosure is shown as follows Figure 8 As shown, determining the final communication mode based on the communication information includes the following steps:

[0104] S601, determining an initial communication mode based on instruction information, where the initial communication mode includes a redundant communication mode and a single communication mode.

[0105] In this step, an initial communication mode is determined based on the instruction information, and the initial communication mode includes a redundant communication mode and a single communication mode.

[0106] Among them, the single communication mode also includes a first communication mode and a second communication mode, wherein the first communication mode is a mode for transmitting data using Zigbee communication mode, the second communication mode is a mode for transmitting data using Bluetooth communication mode, and the redundant communication mode is a mode for simultaneously transmitting different data using Zigbee and Bluetooth.

[0107] S602: When the initial communication mode is a redundant communication mode, determine a final communication mode based on signal strength information.

[0108] After completing the above step S601, in this step, when the initial communication mode is the redundant communication mode, the final communication mode is determined based on the signal strength information; that is, when the initial communication mode is the redundant communication mode, the final communication mode needs to be determined by the signal strength information; specifically, Fig. 9 The flowchart of the steps of determining the final communication mode based on the signal strength information provided by the present disclosure is shown as follows Fig. 9 As shown, determining the final communication mode based on the signal strength information includes the following steps:

[0109] S701: When the signal strength of the first communication mode is greater than a third threshold and the signal strength of the second communication mode is greater than a fourth threshold, determine that the final communication mode is a redundant communication mode.

[0110] In this step, when the signal strength of the first communication mode is greater than the third threshold, and the signal strength of the second communication mode is greater than the fourth threshold, the communication mode is determined to be a redundant communication mode; that is, when the strengths of the first communication mode and the second communication mode are both greater than their required preset thresholds, it indicates that both meet the communication requirements. At this time, a redundant communication mode is adopted, and Zigbee and Bluetooth are used to transmit different data simultaneously; wherein the third threshold and the fourth threshold are the required thresholds of the preset first communication mode and the second communication mode, respectively, and can be set based on the actual requirements of the communication, and the two can be the same or different.

[0111] S702: When only the signal strength of the first communication mode is greater than a third threshold, determine that the final communication mode is the first communication mode.

[0112] In this step, when only the signal strength of the first communication mode is greater than the third threshold, the communication mode is determined to be the first communication mode; that is, only the first communication mode meets the requirements for stable data transmission, and the signal strength of the second communication mode is insufficient to support its stable data transmission; therefore, only the first communication mode is used to transmit data to ensure the stability of transmission.

[0113] S703: When only the signal strength of the second communication mode is greater than a fourth threshold, determine that the final communication mode is the second communication mode.

[0114] In this step, when only the signal strength of the second communication mode is greater than the fourth threshold, the communication mode is determined to be the second communication mode; that is, only the second communication mode meets the requirements for stable data transmission, and the signal strength of the first communication mode is insufficient to support its stable data transmission; therefore, only the second communication mode is used to transmit data to ensure the stability of transmission.

[0115] S704: When the signal strength of the first communication mode is lower than the third threshold and the signal strength of the second communication mode is lower than the fourth threshold, terminate the communication connection between the remote controller and the controller of the hydraulic support.

[0116] In this step, when the signal strength of the first communication mode is lower than the third threshold and the signal strength of the second communication mode is lower than the fourth threshold, it means that the signal transmission at this time is poor and cannot meet the stable data transmission. In order to avoid damage to the equipment caused by instability during data transmission, the communication connection between the remote control and the controller of the hydraulic support is terminated at this time.

[0117] When the initial communication mode is a single communication mode, determine whether the signal strength of the first communication mode is greater than the third threshold; if the signal strength of the first communication mode is greater than the third threshold, use the first communication mode to transmit data; if the signal strength of the first communication mode is not greater than the third threshold, determine whether the signal strength of the second communication mode is greater than the fourth threshold; if the signal strength of the second communication mode is greater than the fourth threshold, use the second communication mode to transmit data. If the signal strength of the second communication mode is not greater than the fourth threshold, it means that the signal transmission at this time is poor and cannot meet the stable transmission of data. In order to avoid damage to the equipment caused by instability during data transmission, at this time, terminate the communication connection between the remote control and the controller of the hydraulic support.

[0118] S503: Establish a communication connection between the remote controller and the controller of the hydraulic support based on the final communication mode.

[0119] After completing the above step S502, in this step, based on the selected communication mode, a communication connection is automatically established between the remote controller and the controller of the hydraulic support to perform data transmission.
