Description
Technical Field
[0001] The present disclosure relates to the technical field of working face monitoring, and particularly to a monitoring and control method, device, storage medium and electronic device for fully-mechanized coal mining working face. Background Art
[0002] The cable clamp of a shearer belongs to a protection channel that connects through pins or bolts to protect the power supply cable of the shearer, and it can be a chain-like bendable housing that wraps the cable. When the shearer moves for operation, the power supply cable will follow the shearer. Since the cable is prone to breakage during movement in the harsh underground working environment, the cable clamp can enhance the protection of the cable. When the shearer moves forward, the cable clamp is in a straightened state of one layer. At this time, if the shearer switches its traveling direction to reverse, the cable clamp will be folded back and dragged. Therefore, the cable clamp will be folded and form a folding point at the folding place, and this point is the folding point of the shearer cable clamp. The cable trough is the track for the movement of the shearer cable clamp, which is used to protect the cable clamp from moving without obstruction and interference from foreign objects.
[0003] In the prior art, the inspection of the fully-mechanized coal mining working face is mainly realized through an inspection device, which is equipped with a high-definition camera to achieve rapid inspection of the entire working face; an equipment platform is set on the inspection device to facilitate the installation of various equipment, which provides convenience for scientific research such as straightening the working face, coal and rock decomposition, coal gangue identification, and abnormal conditions of working face equipment, and also provides convenience for the installation of sensors, and is convenient, reliable and easy to maintain.
[0004] In addition, the inspection of the fully-mechanized coal mining working face can also adopt the scheme of a cable-dragging inspection device. Specifically, by means of the power of the cable-dragging mechanism of the fully-mechanized coal mining working face, the inspection device is driven to move. Generally, the inspection device includes a frame, a traveling mechanism and a detection device. The traveling mechanism is arranged at the lower part of the frame, and the detection device is arranged at the upper part of the frame; a cable-dragging track is set on the inspection route of the fully-mechanized coal mining working face, and a wire groove is arranged on the cable-dragging track. The traveling mechanism of the inspection device is slidably arranged in the wire groove. One end of the inspection device is connected to a towing rope, and the other end of the inspection device is connected to the cable through a cable-dragging gear; the detection device is connected to a wireless transceiver module and a battery. The inspection device is towed on the cable-dragging track through the towing rope, and the inspection function is realized through the detection device, and the video recording and image capture functions are realized on the working face, which can not only meet the general requirements of working face inspection, but also dynamically monitor the process of cable dragging.
[0005] However, most of the above existing solutions adopt inspection-type face mobile robots. During inspection, a pan-tilt camera is carried to complete the face inspection, and the function of inspecting cable clamps is completed incidentally. However, the above solutions have the disadvantages of untimely inspection, difficult track laying, and high equipment cost. In particular, there is a problem that continuous derailment monitoring of the mobile folding part of the cable clamp, the cable clamp out-of-groove opening, and the connection area of the shearer cannot be achieved.

[0027] Reference is made herein to the drawings to describe the various solutions and features of the present disclosure.
[0028] It should be understood that various modifications can be made to the embodiments applied herein. Therefore, the above description should not be regarded as a limitation, but only as an example of the embodiments. Those skilled in the art will think of other modifications within the scope and spirit of the present disclosure.
[0029] The drawings included in the specification and constituting a part of the specification illustrate the embodiments of the present disclosure, and are used together with the general description of the present disclosure given above and the detailed description of the embodiments given below to explain the principles of the present disclosure.
[0030] These and other features of the present disclosure will become apparent from the following description of the preferred forms of the embodiments given by way of non-limiting examples with reference to the drawings.
[0031] It should also be understood that although the present disclosure has been described with reference to some specific examples, those skilled in the art can surely implement many other equivalent forms of the present disclosure, which have the features as described in the claims and thus are all within the protection scope defined hereby.
[0032] When combined with the accompanying drawings, the above and other aspects, features and advantages of the present disclosure will become more obvious in view of the following detailed description.
[0033] Specific embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments claimed are only examples of the present disclosure, which can be implemented in various ways. Well-known and / or repetitive functions and structures are not described in detail to avoid obscuring the present disclosure with unnecessary or redundant details. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but are merely used as a basis and representative basis for the claims to teach those skilled in the art to use the present disclosure in substantially any suitable detailed structure in various ways.
[0034] This specification may use the phrase "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", which may all refer to one or more of the same or different embodiments according to the present disclosure.
[0035] The first embodiment of the present disclosure provides a monitoring and control method for a fully mechanized coal mining face. To meet the on-site monitoring requirements for the cable clamp of the shearer on the fully mechanized coal mining face, the embodiments of the present disclosure mainly perform real-time monitoring on the fully mechanized coal mining face, especially for the shearer 1 operating on the fully mechanized coal mining face and the cable clamp connected to the shearer, etc.
[0036] As Figure 1 shown, the monitoring and control method includes:
[0037] S101, determining a first support number corresponding to the real-time position of the shearer.
[0038] In this step, the first support number corresponding to the real-time position of the shearer is determined. In this embodiment, the shearer 1 operates on the fully-mechanized coal mining face and travels in different directions on the fully-mechanized coal mining face, while driving the cable clamping plate 2 to move continuously. In order to determine the positions of, for example, the shearer 1 and the cable clamping plate 2 on the fully-mechanized coal mining face for the purpose of monitoring, supports are sequentially arranged along the length direction of the fully-mechanized coal mining face, and the positions on the fully-mechanized coal mining face correspond to the supports; at the same time, cameras are installed on each support to monitor the vicinity of each support through the cameras. Of course, if the length of the fully-mechanized coal mining face is relatively long, a certain number of supports can be selected from all the supports to install cameras, so as to reduce costs without affecting monitoring.
[0039] Further, each of the supports arranged here is sequentially numbered in order along the length direction of the fully-mechanized coal mining face, and the numbering is determined based on the length of the fully-mechanized coal mining face and the distance between the supports. In this embodiment, taking the total number of supports n = 200 arranged on the fully-mechanized coal mining face as an example, the support numbering starts from one end of the fully-mechanized coal mining face with the 1# support as the starting point and ends at the other end of the fully-mechanized coal mining face, that is, the other end ends with the 200# support as the end point.
[0040] In addition, an out-of-slot opening 3 of the cable clamping plate 2 is arranged on the fully-mechanized coal mining face. Here, the out-of-slot opening 3 is the grounding point of the cable in the cable clamping plate 2, and it can be set at the central position along the length direction of the fully-mechanized coal mining face. For example, the position of the out-of-slot opening 3 can be set at the 99# support. In this step, since the shearer 1 operates on the fully-mechanized coal mining face, it is necessary to first determine the real-time position of the shearer 1, and the real-time position here is determined by the first support number P1. For example, the shearer 1 is located at the position corresponding to the 50# support.
[0041] S102. Determine the second support number corresponding to the cable clamping plate turning point based on the traveling direction of the shearer and the first support number.
[0042] After determining the first support number corresponding to the real-time position of the shearer through the above steps, in this step, based on the traveling direction of the shearer and the first support number, determine the second support number corresponding to the cable clamping plate turning point. In this embodiment, the shearer 1 travels along the length direction of the fully mechanized mining face. Therefore, the traveling direction of the shearer 1 is related to the position of the cable clamping plate turning point of the cable clamping plate 2. In addition, since the grounding end of the cable clamping plate 2 is fixed at the position of the out-of-slot opening 3 here, the length of the cable clamping plate 2 is generally a fixed length. For this reason, based on the traveling direction of the shearer 1 and the real-time position of the shearer 1, the position of the cable clamping plate turning point can be determined. Here, the above different positions can be represented by the corresponding support numbers, so as to facilitate the rapid determination of the position.
[0043] Further, as Figure 2 shown, the determining the second support number corresponding to the cable clamping plate turning point based on the traveling direction of the shearer and the first support number includes:
[0044] S201, when the traveling direction of the shearer is consistent with the direction in which the support number decreases, the second support number is determined by the total number of supports and the first support number.
[0045] In this step, when the traveling direction of the shearer is consistent with the direction in which the support number decreases, the second support number is determined by the total number of supports and the first support number. Specifically, it can be determined by the following formula:
[0046] P2 = N - (N – P1) / 2; where P2 is the second support number, N is the total number of supports, and P1 is the first support number.
[0047] S202, when the traveling direction of the shearer is consistent with the direction in which the support number increases, the second support number is determined by the first support number.
[0048] In this step, when the traveling direction of the shearer is consistent with the direction in which the support number increases, the second support number is determined by the first support number. Specifically, it can be determined by the following formula:
[0049] P2 = P1 / 2, where P2 is the second support number and P1 is the first support number.
[0050] Specifically, the position of the out-of-slot opening 3 of the cable clamping plate 2 here is generally fixed, and the shearer 1 can travel relative to the out-of-slot opening 3 to any side. On the one hand, as Figure 3 shown, when the shearer 1 travels towards Figure 4When traveling to the left in the figure, P1 is the real-time position of the coal shearer 1, and P2 is the position of the cable clamping plate turning point. In this case, the position of the cable clamping plate turning point is on the right side of the outlet 3. Among them, P3 is the position of the outlet 3 of the cable clamping plate 2, and here P2 = N - (N - P1) / 2.
[0051] On the other hand, as Figure 5 shown, when the coal shearer 1 travels to the right in the figure, P1 is the real-time position of the coal shearer 1, and P2 is the position of the cable clamping plate turning point. In this case, the cable clamping plate turning point is on the left side of the outlet 3. Among them, P3 is the position of the outlet 3 of the cable clamping plate 2, and here p2 = p1 / 2.
[0052] S103, display at least the images of the real-time position of the coal shearer and the position of the cable clamping plate turning point.
[0053] After determining the second support number corresponding to the cable clamping plate turning point based on the traveling direction of the coal shearer and the first support number through the above step S102, in this step, at least display the images of the real-time position of the coal shearer and the position of the cable clamping plate turning point. Among them, the real-time position of the coal shearer here is the image collected by the camera on the support with the first support number, and the position of the cable clamping plate turning point here is the image collected by the camera on the support with the second support number, so as to monitor the operation of the coal shearer 1 and the positions such as the cable clamping plate turning point.
[0054] Here, the display of the image is realized through a display device such as a monitor. The monitor here can display at least 2 pictures, so as to realize the display of the images of the above two positions. In a preferred embodiment, as Figure 6 shown, the number of pictures d of the monitor is 9, so as to form a display picture with a 3*3 splicing layout.
[0055] Furthermore, the monitoring and control method further includes:
[0056] Display the images of other predetermined positions based on the number of displayable pictures.
[0057] In addition to displaying at least the images of the real-time position of the coal shearer and the position of the cable clamping plate turning point through a monitor and other devices, when the number of displayable pictures is large, the images of other predetermined positions can also be displayed based on the number of displayable pictures, so as to monitor more positions and facilitate the operator to master more actual operation conditions on the fully-mechanized coal mining face. Here, for example, for a monitor that can display 9 pictures, the images collected by 7 other predetermined position cameras can also be displayed.
[0058] Furthermore, asFigure 3 As shown, the image for displaying other predetermined positions based on the number of displayable screens includes:
[0059] S301, determining the third support number corresponding to the cable cleat outlet based on the total number of supports in the fully mechanized coal mining face;
[0060] S302, determining a first camera group based on the first support number and the second support number, where the first camera group includes a first camera to be displayed, and the number of the first cameras to be displayed is determined based on the number of displayable screens;
[0061] S303, determining a second camera group based on the first camera to be displayed and the camera corresponding to the third support number;
[0062] S304, displaying the images of the second cameras to be displayed in the second camera group according to a predetermined rule.
[0063] In this embodiment, after determining the position of the cable cleat turning point by judging through the traveling direction of the shearer 1 and combining the first support number corresponding to the real-time position of the shearer 1, all the cameras between the real-time position of the shearer 1 (represented by the first support number P1) and the position of the cable cleat turning point (represented by the second support number P2) are obtained as the first cameras to be displayed and form a first target camera device group g1, which can also be defined as the first camera group.
[0064] Further, for example, when the number of displayable screens of the monitor is 9, 2 cameras corresponding to the cable cleat turning point and the real-time position of the shearer 1 are determined from the first target camera device group g1; considering that there are still 7 remaining displayable screens, for this reason, the uniform screening algorithm is further used to determine 6 first cameras to be displayed from the remaining first cameras to be displayed in the first target camera device group g1. At the same time, the camera on the support corresponding to the position of the outlet 3 of the cable cleat 2 can also be selected, and finally a new second target camera device group g2 is formed in a predetermined order, which can also be defined as the second camera group. Finally, the images obtained by the second cameras to be displayed in the second target camera device group g2 are sequentially displayed on the monitor, and here it can be displayed according to the predetermined display rule, such as Figure 4 As shown.
[0065] In addition, if the number of cameras between the real-time position of the shearer 1 and the position of the cable cleat turning point in the first target camera device group g1 does not meet the requirement of the number of displayable screens, for example, when 9 display screens cannot be achieved, 2 cameras outside the above intervals can be selected to supplement the second target camera device group g2.
[0066] In summary, as Figure 7 shown, in this embodiment, during the operation of the shearer 1, the real-time position and traveling direction of the shearer 1 are obtained. At the same time, as the cable clamping plate 2 moves, by determining the position of the turning point of the cable clamping plate in real time, the operation of the area between the turning point of the cable clamping plate and the shearer 1 or between the turning point of the cable clamping plate and the out-of-slot opening 3 is monitored by video.
[0067] Furthermore, in this embodiment, the display can also be divided into multiple display screens, and each display screen displays the image of one camera. In this way, the limited monitoring screens can be evenly and dispersedly covered over the entire area where the cable clamping plate 2 with a dynamically variable length is located. In addition, the position of the out-of-slot opening 3 can be continuously monitored through a fixed display screen.
[0068] Finally, through intelligent recognition of the collected video data, for example, after recognizing abnormal conditions such as derailment of the cable clamping plate 2, specified image screen annotation and voice alarm for the derailed area are carried out to prompt on-site operators.
[0069] In the embodiment of the present disclosure, the position of the turning point of the cable clamping plate is determined based on the traveling direction of the shearer and the real-time position of the shearer. Through the camera corresponding to the above position and other important cameras, the video image is thus displayed on the display. In addition, as the shearer continuously travels, the video image on the display can be dynamically switched to ensure that all key areas of the cable clamping plate are always monitored.
[0070] The embodiment of the present disclosure is based on the camera equipment arranged on the fully-mechanized coal mining face. The on-site deployment is simple, without the need to lay tracks for mobile inspection devices, realizing equipment reuse and cost reduction. Through video images, the inspection and monitoring of the cable clamping plate are realized. In particular, it can accurately and continuously monitor key areas such as the turning point of the cable clamping plate and the out-of-slot opening, realizing real-time monitoring of the cable clamping plate at any time. Compared with periodic inspection, it has the advantage that the time period can be completely covered.
[0071] Based on the same inventive concept as the above first embodiment, the second embodiment of the present disclosure provides a monitoring and control device for a fully-mechanized coal mining face, which includes a first determination module, a second determination module, and a display control module that are coupled to each other, where:
[0072] The first determination module is used to determine the first support number corresponding to the real-time position of the shearer;

[0079] Furthermore, when the traveling direction of the shearer is consistent with the direction in which the support numbers decrease, the second support number is determined by the following formula: P2 = N - (N - P1) / 2; where P2 is the second support number, N is the total number of supports, and P1 is the first support number; when the traveling direction of the shearer is consistent with the direction in which the support numbers increase, the second support number is determined by the following formula: P2 = P1 / 2, where P2 is the second support number and P1 is the first support number.
[0080] Furthermore, the display control module is further configured to:
[0081] Display images of other predetermined positions based on the number of displayable screens.
[0082] Furthermore, the display control module includes:
[0083] A third determination unit, configured to determine the third support number corresponding to the cable clamp outlet based on the total number of supports in the fully mechanized coal mining face;

[0086] A display control unit, configured to display images of the second cameras to be displayed in the second camera group according to a predetermined rule.
[0087] Further, when the number of the first cameras to be displayed in the first camera group does not meet the requirement of the number of displayable pictures, cameras outside the interval between the real-time position of the shearer and the position of the cable clamping plate turning point are selected to supplement the second target camera device group.
