[0038] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0039] The following describes the video monitoring data acquisition control system and method for the fully mechanized mining face according to the embodiments of the present application with reference to the accompanying drawings.

[0040] Figure 1 This is a structural diagram of a video monitoring data acquisition and control system for a fully mechanized mining face proposed in an embodiment of the present application, as shown in FIG. Figure 1 As shown, the system includes: a camera 1, multiple infrared sensors 2, a hydraulic support pressure sensor 3, a coal mining machine encoder 4, a scraper current sensor 5 and a microcontroller 6.

[0041] Among them, such as Figure 2 As shown, the camera 1 and the microcontroller 6 are arranged on the top beam of the hydraulic support. The camera 1 is in a standby state under normal conditions, that is, the camera 1 is in a standby closed state when no opening control command is received, and does not collect video data.

[0042] The present application sets the microcontroller 6 on the top beam of the hydraulic support, which can prevent the microcontroller 6 from being damaged during underground operations, for example, preventing passing equipment or personnel from touching the microcontroller 6.

[0043] A plurality of infrared sensors 2 are arranged on the columns of the hydraulic support, and the plurality of infrared sensors 2 are used to detect whether there are workers around the hydraulic support. In one embodiment of the present application, Figure 2 As shown, two infrared sensors 2 are respectively arranged in front of and behind the support of the hydraulic support, so as to detect the workers passing by the hydraulic support.

[0044] The hydraulic support pressure sensor 3 is used to detect changes in the pressure applied to the hydraulic support, the shearer encoder 4 is used to detect the distance between the shearer and the hydraulic support, and the scraper current sensor 5 is used to detect changes in the scraper current. It should be noted that the hydraulic support pressure sensor 3, the shearer encoder 4, and the scraper current sensor 5 are all existing sensors in coal mines. Based on the use of various common equipment in the fully mechanized mining working face, this application completes the hardware setup of the acquisition and control system by simply adding an infrared sensor 2 and a microcontroller 6.

[0045] Microcontroller 6 is in communication with other devices in the system. It determines whether a target scene to be monitored exists based on real-time data detected by various sensors. If any of multiple target scenes exists, it sends an activation command to camera 1 to collect video surveillance data. These multiple target scenes include: a shearer passing a hydraulic support, an operator passing a hydraulic support, changes in scraper load, and changes in working face support requirements.

[0046] Specifically, the microcontroller 6 is connected to the aforementioned camera 1, the plurality of infrared sensors 2, the hydraulic support pressure sensor 3, the shearer encoder 4, and the scraper current sensor 5 for data exchange. The microcontroller 6 receives real-time data collected by the plurality of infrared sensors 2, the hydraulic support pressure sensor 3, the shearer encoder 4, and the scraper current sensor 5, and can send control instructions to the camera 1.

[0047] Among them, for the hydraulic support camera in the comprehensive mining working face, the effective video monitoring data is only the data in a few scenarios such as the coal mining machine cutting coal through the hydraulic support, the workers passing the hydraulic support, the scraper's transport volume changes, and the working face support demand changes (such as special working conditions such as periodic pressure and deviation of the working face). Therefore, this application only turns on camera 1 during the time periods when these target scenes that need to be monitored occur.

[0048] In practice, microcontroller 6 performs mathematical calculations and logical analysis based on the real-time data detected by each sensor to determine whether the target scene to be monitored exists. If at least one target scene exists, microcontroller 6 sends a power-on command to camera 1. Upon receiving the power-on command, camera 1 switches from standby mode to active mode and begins collecting video surveillance data.

[0049] In one embodiment of the present application, the height values ​​of the plurality of infrared sensing sensors 2 from the bottom plate of the work surface are determined based on the target object to be detected.

[0050] For example, when an infrared sensor is used to detect whether workers are passing by a hydraulic support, the infrared sensor can be installed on the hydraulic support column at a height of 1.2m from the bottom plate based on factors such as the height of the workers, the detection angle, and the detection range, so as to detect workers passing by.

[0051] In some other embodiments, the height of the infrared sensing sensor 2 from the bottom plate of the work surface can also be adjusted. For example, when it is necessary to detect the passing working equipment, the height of the infrared sensor from the bottom plate can be raised or lowered according to the position of the heating area of ​​the equipment to be detected.

[0052] In one embodiment of the present application, the system further includes a left camera and a right camera, respectively, disposed on a left hydraulic support and a right hydraulic support adjacent to the hydraulic support. A microcontroller is communicatively coupled to the left camera and the right camera, respectively. The microcontroller is further configured to send an activation command to the left camera and the right camera upon determining that a worker is passing through the target scene of the hydraulic support.

[0053] Specifically, when this embodiment detects that there is a worker passing by the left hydraulic support, it controls the cameras on the left hydraulic support and the right hydraulic support adjacent to the current hydraulic support to turn on, so as to more comprehensively monitor the process of the worker passing by the hydraulic support, and can collect complete video monitoring data from the worker starting to walk towards the current hydraulic support to moving away from the current hydraulic support.

[0054] It should be noted that the number of cameras 1 and microcontrollers 6 installed in this application can be determined based on actual factors such as monitoring needs and monitoring costs. As an example, a camera 1 can be installed for every three hydraulic supports, and the camera 1 is installed on the hydraulic support located in the middle. The microcontroller 6 then communicates with the cameras on the two nearest hydraulic supports with cameras installed. When it is determined that there is a worker passing through the target scene of the current hydraulic support, an opening instruction is sent to the left camera and the right camera. As another example, a microcontroller 6 can also be installed in an area of ​​the comprehensive mining working face, and the microcontroller 6 can uniformly control the opening and closing of the cameras on each hydraulic support in the area to further reduce hardware costs.

[0055] It is understood that this application uses several sensors to monitor special conditions on the work surface to determine whether to open the camera to collect data. This can streamline video data, effectively detect changes in the work surface, and reduce the pressure on video data transmission and storage. At the same time, this application utilizes existing sensors, and the several sensors used are all low-cost, which can reduce monitoring and control costs.

[0056] In summary, the video surveillance data acquisition and control system for a fully mechanized mining face in the present embodiment of the present invention, in addition to the various common sensors already present in a fully mechanized mining face, adds infrared sensors and a microcontroller. These sensors collect various monitoring data related to the hydraulic supports in real time, and perform calculations and logical control on the collected data signals to determine whether to activate the camera for data acquisition. Consequently, the system can activate the camera for video surveillance in several key scenarios where fully mechanized mining face monitoring is required. By using a rational optimization method to control the activation time of the hydraulic support camera, the system only collects valid video surveillance data at specific times, reducing the amount of useless data collected by the hydraulic support camera. Consequently, the system effectively reduces the amount of video surveillance data collected, alleviating the burden of video data transmission, storage, and computation in coal mines, improving the efficiency of video surveillance in fully mechanized mining faces, and lowering monitoring costs. Furthermore, by rationally positioning the installation locations of the newly added equipment, the system enhances sensor detection effectiveness and prevents damage to related equipment during underground operations. Consequently, the system improves the rationality, pertinence, and intelligence of video surveillance data acquisition for fully mechanized mining faces.

[0057] In order to more clearly illustrate the specific implementation process of the comprehensive mining face video monitoring data acquisition and control system of this application for logical operations and the opening or closing control of the camera, a comprehensive mining face video monitoring data acquisition and control method proposed in the embodiment of this application is described in detail below. This method is applied to the comprehensive mining face video monitoring data acquisition and control system in the above embodiment, that is, the control method of this embodiment is realized by performing relevant control on the system in the above embodiment. The various devices in the control system involved in this method can be referred to the above embodiment and will not be repeated here. The executor of the data acquisition and control method of this application can be the microcontroller in the above system embodiment.

[0058] Figure 3 This is a flow chart of a method for collecting and controlling video monitoring data of a fully mechanized mining face proposed in an embodiment of the present application, as shown in FIG. Figure 3 As shown, the method includes the following steps:

[0059] Step S101: Acquire a variety of data collected in real time by a plurality of infrared sensors preset on the hydraulic support, a hydraulic support pressure sensor, a coal mining machine encoder, and a scraper current sensor.

[0060] Specifically, the configuration of each sensor and the corresponding collected data in this step can refer to the relevant description in the above system embodiment, which will not be repeated here.

[0061] Step S102: judging whether a determination condition corresponding to any target scene among a plurality of target scenes to be monitored is satisfied based on the various data collected in real time.

[0062] Specifically, this step determines whether each of the multiple target scenes to be monitored occurs based on the various real-time data collected by each sensor through corresponding judgment logic, so as to control the camera to turn on when it is determined that at least one target scene exists.

[0063] In one embodiment of the present application, whether the judgment conditions corresponding to any target scene among multiple target scenes to be monitored are met is determined, including: when the change in the pressure of the hydraulic support detected by the hydraulic support pressure sensor exceeds the pressure change threshold, it is determined that the judgment conditions corresponding to the working face support demand change scene are met; when the distance between the coal mining machine and the hydraulic support detected by the coal mining machine encoder is less than the distance threshold, it is determined that the judgment conditions corresponding to the coal mining machine passing through the hydraulic support scene are met; when the change in the current of the scraper detected by the scraper current sensor exceeds the current change threshold, it is determined that the judgment conditions corresponding to the scraper transportation volume change scene are met; when multiple infrared sensing sensors detect that there are operating personnel within the preset range of the hydraulic support, it is determined that the judgment conditions corresponding to the operating personnel passing through the hydraulic support scene are met.

[0064] For example, in this embodiment, Figure 4 As shown, for each camera, when the hydraulic support pressure sensor detects that the pressure change on the hydraulic support exceeds 20% (i.e., the pressure change threshold), it is determined that the judgment condition for the working face support demand change scenario is met. When the coal mining machine encoder detects that the distance between the coal mining machine and the current hydraulic support is 2 frames (i.e., the distance threshold, indicating that the coal mining machine is located between the two adjacent hydraulic supports in front and behind the current hydraulic support), it is determined that the judgment condition for the coal mining machine passing through the hydraulic support scenario is met. When the scraper current monitoring sensor monitors that the scraper current change exceeds 20% (i.e., the current change threshold, indicating that the scraper transport volume has changed or has become stuck, etc.), it is determined that the judgment condition for the scraper transport volume change scenario is met. When the infrared sensor detects that someone passes by the front and back of the hydraulic support, for example, when an operator is detected within the preset range before and after the current hydraulic support, it is determined that the judgment condition for the operator passing through the hydraulic support scenario is met.

[0065] Based on the above embodiment, as described above, when the present application detects the presence of a worker passing by the current hydraulic support, it also controls the cameras on the left hydraulic support and the right hydraulic support adjacent to the current hydraulic support to turn on. Therefore, for the left and right hydraulic supports adjacent to the current hydraulic support, the camera on the current hydraulic support is also controlled by the detection results of the adjacent left and right hydraulic supports. That is, in one embodiment of the present application, determining whether the determination conditions corresponding to any target scene among multiple target scenes to be monitored are met also includes: when it is detected that there is a worker within a preset range of the left hydraulic support adjacent to the current hydraulic support, determining that the determination conditions corresponding to the scene of the worker passing by the left hydraulic support are met; when it is detected that there is a worker within a preset range of the right hydraulic support adjacent to the current hydraulic support, determining that the determination conditions corresponding to the scene of the worker passing by the right hydraulic support are met.

[0066] Specifically, if Figure 4 As shown, when the left hydraulic support or the right hydraulic support adjacent to the current hydraulic support detects the presence of an operator within a preset range, it is also determined that the conditions for activating the camera on the current hydraulic support exist. The implementation method for the left hydraulic support or the right hydraulic support to detect and determine whether an operator is within the preset range is the same as the detection and determination method of the current hydraulic support and will not be repeated here.

[0067] Step S103: When the determination conditions are met, a start instruction is sent to the camera on the hydraulic support to switch the camera from the standby state to the on state to collect video monitoring data.

[0068] Specifically, when any of the determination conditions described in step S102 is met, an on command is sent to the camera on the current hydraulic support, the camera is switched from the standby state to the on state, and video surveillance data is collected. Figure 4 As shown, when one or more of the above determination conditions are met, the camera is turned on.

[0069] Furthermore, in one embodiment of the present application, after the camera is switched from the standby state to the on state, it also includes: when the determination conditions corresponding to the multiple target scenes to be monitored are not met, sending a shutdown instruction to the camera.

[0070] Specifically, in this embodiment, based on the information continuously collected by the above-mentioned sensors, it is determined that none of the above-mentioned target scenes exist. That is, after the above-mentioned special working conditions are completed, when the determination conditions corresponding to each target scene are not met, the camera is controlled to be turned off to prevent the camera from continuing to collect useless video surveillance data.

[0071] In summary, the video surveillance data acquisition and control method for the fully mechanized mining face implemented in this application can activate the camera for video surveillance in several important scenarios where the fully mechanized mining face needs to be monitored. By controlling the activation time of the hydraulic support camera through a reasonable optimization method, only valid video surveillance data at specific moments is collected, reducing useless data collected by the hydraulic support camera. As a result, this method can effectively reduce the amount of video surveillance data collected, reduce the pressure on video data transmission, storage, and calculation in coal mines, improve the efficiency of video surveillance of fully mechanized mining faces, and reduce monitoring costs.

[0072] To implement the above-mentioned embodiments, this application also proposes a device for collecting and controlling video surveillance data from a fully mechanized mining face. This device corresponds to the method for collecting and controlling video surveillance data from a fully mechanized mining face described in the second embodiment. As a possible implementation, this device can be integrated into the microcontroller described in the first embodiment to implement the relevant control functions of the microcontroller. Figure 5 This is a structural diagram of a video monitoring data acquisition and control device for a fully mechanized mining face proposed in an embodiment of the present application, as shown in FIG. Figure 5 As shown, the device includes: an acquisition module 100, a judgment module 200 and a control module 300.

[0073] The acquisition module 100 is used to acquire a variety of data collected in real time by a plurality of infrared sensors preset on the hydraulic support, a hydraulic support pressure sensor, a coal mining machine encoder and a scraper current sensor.

[0074] The judgment module 200 is used to judge whether a judgment condition corresponding to any target scene among multiple target scenes to be monitored is met based on multiple data collected in real time.

[0075] The control module 300 is used to send an on instruction to the camera on the hydraulic support to switch the camera from a standby state to an on state to collect video monitoring data when the determination conditions are met.

[0076] In one embodiment of the present application, the control module 300 is further configured to: send a shutdown instruction to the camera when the determination conditions corresponding to the multiple target scenes to be monitored are not satisfied.
