[0040] The present invention proposes a matrix communication system and method for a fully mechanized mining face with ultra-large mining height, so as to better meet the communication needs of the staff and equipment in the underground working space.

[0041] Figure 1 A block diagram of a matrix communication system for a fully mechanized mining face with ultra-large mining height provided in an embodiment of the present invention. Figure 2 The schematic diagram of the connection principle of the electrical components of the matrix communication system for the ultra-large mining height fully mechanized mining face provided by the embodiment of the present invention is shown in FIG. The matrix communication system for the ultra-large mining height fully mechanized mining face in the present invention can be referred to as the communication system.

[0042] like Figure 1As shown, the matrix communication system of the ultra-large mining height fully mechanized mining working face includes a communication controller 10 and a communication equipment group. The communication equipment group includes a lateral follow-up wireless communication base station device and a top wireless communication covering device. The lateral follow-up wireless communication base station device includes a working face displacement monitoring module 11, a mobile device 12 and a micro wireless communication base station 13. Among them, the communication equipment group is arranged on the side wall of the tunnel. When the number of communication equipment groups is 1, it can be arranged on any side wall on both sides of the tunnel. The number of communication equipment groups can be 2, and the two communication equipment groups are symmetrically arranged on the side walls of the tunnel on both sides of the coal mining machine.

[0043] In this embodiment, the mobile device 12 is provided with a movable part. The working face displacement monitoring module 11, the micro wireless communication base station 13 and the top wireless communication coverage device are all installed on the movable part. Specifically, the movable part includes an inner side surface facing the coal mining machine 100, a top surface facing the roof and a front end facing the comprehensive mining working face. The working face displacement monitoring module 11 is installed at the front end of the movable part and faces the comprehensive mining working face. The micro wireless communication base station 13 is installed on the inner side surface of the movable part and is located on the outer side of the coal mining machine 100. The top wireless communication coverage device is installed on the top surface of the movable part.

[0044] Take two communication equipment groups as an example. Figure 3 This is a schematic diagram of the top view of the structure principle of the underground layout of the matrix communication system of the ultra-high mining height fully mechanized mining working face provided by the embodiment of the present invention.

Figure 3 As shown, 103 is a fully mechanized mining face, 100 is a coal mining machine, and the mobile devices 12 of the two communication equipment groups are symmetrically arranged on the side walls of the coal mining machine 100. The micro wireless communication base station 13 is installed on the inner side of the movable part of the mobile device 12 and is located on the outer side of the coal mining machine 100.

[0045] The positional relationship between the side-following wireless communication base station device and the top wireless communication covering device in the communication equipment group is described in detail below.

[0046] Figure 4 A schematic diagram of partial positional relationships of a side-following wireless communication base station device provided in an embodiment of the present invention. Figure 5 A cross-sectional view of a partial positional relationship between a mobile device and a micro wireless communication base station provided in an embodiment of the present invention. Figure 6 This is a schematic structural diagram of a top wireless communication coverage device provided by an embodiment of the present invention.

[0047] like Figure 4 and Figure 5As shown, the mobile device 12 includes a lateral slide 121, a braked universal wheel 122 and an electric linear guide 123. The lateral slide 121 is detachably embedded in the side wall of the tunnel of the comprehensive mining working face, and the opening of the lateral slide 121 faces the coal mining machine. The bottom of the track of the electric linear guide 123 is equipped with a braked universal wheel 122, and the rim of the braked universal wheel 122 is against the inner wall of the lateral slide 121. The slider of the electric linear guide 123 is the movable part 124, and the two sides of the opening of the lateral slide 121 are respectively provided with a bending part 1211 for buckling the electric linear guide 123. The working face displacement monitoring module 11 is installed at the front end of the movable part 124. The micro wireless communication base station 13 is installed on the inner side of the movable part 124.

[0048] like Figure 6 As shown, the top wireless communication coverage device includes a lifting bracket 21 and a plurality of wireless expansion modules 22. The bottom of the lifting bracket 21 is mounted on the top surface of the movable portion 124, and the plurality of wireless expansion modules 22 are respectively mounted on the top of the lifting bracket 21. Figure 6 As shown, the top wireless communication coverage device also includes a horizontal support rod 23, the side of the horizontal support rod 23 is detachably mounted on the top of the lifting bracket 21, and multiple wireless expansion modules 22 are detachably mounted on the horizontal support rod 23 at equal intervals (see Figure 4 and Figure 6 The lifting bracket 21 can be in the form of electric lifting or manual lifting. Electric lifting can more conveniently achieve height adaptation. Of course, manual lifting can also be used to adjust the height and then fix it when the equipment is arranged.

[0049] In this embodiment, the number of the universal wheels 122 with brakes in the moving device 12 may be, but is not limited to, 4. When the number of the universal wheels 122 with brakes is 4, they are respectively installed at the four corners of the bottom of the track of the electric linear guide 123.

[0050] In this embodiment, the track lengths of the lateral slide slot 121 and the electric linear guide rail 123 of the moving device 12 are both equal to a set length, which is, for example, 6 meters to 10 meters.

[0051] In this embodiment, the number of the lateral sliding slots in the moving device 12 is at least two.

[0052] In this embodiment, the working face displacement monitoring module in the lateral follow-up wireless communication base station device is used to collect the real-time distance between the moving part of the mobile device and the comprehensive mining working face during the advancement of the comprehensive mining working face, so as to achieve real-time tracking of the advancement position of the comprehensive mining working face 103. Figure 2As shown, the working face displacement monitoring module 11 is in communication connection with the communication controller 10. The working face displacement monitoring module 11 sends the collected real-time distance between the active part and the fully mechanized mining working face to the communication controller 10. The working face displacement monitoring module 11 is a displacement sensor.

[0053] In this embodiment, the micro wireless communication base station 13 is connected to the ground server 102 for communication, and the micro wireless communication base station 13 is used to provide a wireless network for the equipment of the fully mechanized mining face. The equipment of the fully mechanized mining face includes the coal mining machine 100 and nearby equipment. The nearby equipment includes a matching conveyor and the like.

[0054] In this embodiment, the micro wireless communication base station 13 also cooperates with multiple wireless expansion modules to realize an array type wireless communication system. Figure 2 As shown, the wireless expansion module 22 and the micro wireless communication base station 13 are wirelessly networked, thereby achieving regional wireless network coverage, that is, providing more reliable network coverage for the workers or other equipment in the underground working space to access the wireless network. The micro wireless communication base station 13 can cooperate with multiple wireless expansion modules to realize an array wireless communication system. The use of a transverse support rod 23 can enable multiple wireless expansion modules 22 to better form a matrix communication arrangement and stably cover a larger range. The wireless expansion module 22 can be a wireless AP (Access Point) or other wireless expansion technology. In addition, two communication equipment groups are symmetrically arranged on the side walls of the tunnel on both sides of the coal mining machine, which can better increase the stability of the regional wireless network and make the communication of equipment near the comprehensive mining face 103 more stable.

[0055] In this embodiment, the purpose of the mobile device 12 is mainly to adapt to the advancement of the comprehensive mining working face 103. When the comprehensive mining working face 103 advances a certain distance, for example, 6 meters, if no mobile matching is performed at this time, the micro wireless communication base station 13 cannot stably provide wireless network communication for key equipment such as the coal mining machine 100. Therefore, the slider (i.e., the movable part 124) of the electric linear guide rail 123 can be automatically advanced under the control of the communication controller 10, so that the position of the micro wireless communication base station 13 matches the advancement of the comprehensive mining working face 103.

[0056] In this embodiment, the communication controller 10 may be a chip-based communication controller. Figure 2 As shown, the communication controller 10 can be communicatively connected with the micro wireless communication base station 13 to perform data interaction.

[0057] In this embodiment, the communication controller 10 is connected to the mobile device 12, and the communication controller 10 controls the execution action of the mobile device 12 according to the advancement of the comprehensive mining working face 103, and the movable part 124 of the mobile device 12 drives the position of the micro wireless communication base station 13 to match the advancement position of the comprehensive mining working face 103. Specifically, Figure 2 As shown, the communication controller 10 is connected to the electric linear guide 123. The communication controller 10 is used to control the slider (i.e., the movable part 124) of the electric linear guide 123 to move toward the comprehensive mining working face 103 when the real-time distance is greater than the distance threshold so that the positions of the micro wireless communication base station and the top wireless communication covering device match the position of the comprehensive mining working face during the advancement process. The communication controller 10 is also used to control the electric linear guide 123 to enter a new lateral slide rail when the movable part 124 moves to the head end of the electric linear guide 123.

[0058] Taking the case where two lateral chutes 121 are used (the first lateral chutes and the second lateral chutes), the track lengths of the lateral chutes 121 of the moving device 12 and the electric linear guide rail 123 are both equal to 6 meters, and the distance threshold is equal to 6 meters as an example, in the initial state, the head end of the first lateral chutes is arranged on the side wall close to the comprehensive mining working face 103, the head end of the second lateral chutes is close to the tail of the first lateral chutes, and the movable part 124 can be arranged at the tail of the first lateral chutes. At this time, the initial distance between the movable part 124 and the comprehensive mining working face 103 is equal to the distance threshold of 6 meters;

[0059] During the advancement of the comprehensive mining working face 103, if the real-time distance is greater than the distance threshold of 6 meters, the communication controller 10 controls the movable part 124 to advance toward the comprehensive mining working face 103 to keep the real-time distance less than or equal to the distance threshold of 6 meters. When the movable part 124 moves to the head end position of the first lateral chute, it means that the advancement distance of the comprehensive mining working face 103 has reached the length of a lateral chute 121, such as 6 meters. At this time, the second lateral chute is removed, and the second lateral chute is arranged between the comprehensive mining working face 103 and the first lateral chute. The head end of the second lateral chute is arranged on the side wall close to the comprehensive mining working face 103, so that the movable part 124 continues to advance from the tail of the second lateral chute. Every time it reaches the head end of the current lateral chute, the remaining lateral chute is removed and rearranged between the comprehensive mining working face 103 and the current lateral chute until the advancement of the comprehensive mining working face 103 is completed, thereby realizing a relay arrangement.

[0060] Generally, the advancement speed of a comprehensive mining face is 4-6 meters per day. The advancement speed of a super-large mining height comprehensive mining face 103 will be slower. Therefore, under normal circumstances, the lateral chute 121 will be disassembled and assembled once every 1 to 2 days.

[0061] In this embodiment, if Figure 2As shown, an alarm 105 may also be provided, and the alarm 105 is connected to the communication controller 10. The communication controller 10 obtains data from the electric linear guide 123. When the slider (i.e., the movable portion 124) of the electric linear guide 123 is located at the head end of the lateral slideway and cannot move, the communication controller 10 controls the alarm 105 to emit an audible and visual alarm for reminder.

[0062] In this embodiment, if Figure 2 As shown, the matrix communication system for ultra-high fully mechanized mining face also includes multiple relay wireless communication base stations 14. Multiple relay wireless communication base stations 14 are arranged at equal intervals behind the coal mining machine, and the arrangement form can be in the tunnel, on the side wall, or hoisted.

[0063] like Figure 2 As shown, the micro wireless communication base station 13 is sequentially connected to the ground server 102 through multiple relay wireless communication base stations 14. This can further improve the communication quality between the micro wireless communication base station 13 and the ground server 102. In addition, the micro wireless communication base stations 13 of the two communication device groups can be connected to the ground server 102 through the same relay wireless communication base station 14, or can be connected to the ground server 102 through separate relay wireless communication base stations 14.

[0064] In some embodiments, the micro wireless communication base station 13 can also be connected to the ground server 102 by directly connecting via a communication line.

[0065] In this embodiment, the matrix communication system of the ultra-large mining height fully mechanized mining face also includes an emergency communication device. Figure 2 As shown, the emergency communication device includes a plurality of communication sockets 31 and communication lines 32. The plurality of communication sockets 31 are respectively connected to the ground server 102 through the communication lines 32 for communication.

[0066] Figure 7 This is a schematic diagram of the structure principle of the emergency communication device provided by the embodiment of the present invention. Figure 7 As shown, multiple communication sockets 31 are fixedly installed at equal intervals at the bottom of the fixed track 101 in the lane, and each communication socket 31 is provided with a plurality of communication sockets 311 for emergency communication, and each communication socket 311 is connected to the ground server communication 102 through a communication line. For example, a communication socket 31 is set at every 3-6 meters, and a communication line 32 is directly connected. Since it is arranged along the fixed track 101, when an object is pressed down on the top, it will not cause physical damage to the communication socket 31. When communication is impossible in an emergency state, a matching communication plug, such as a data cable, can be used to insert the communication socket 311 of the nearest communication socket 31 to realize emergency communication, which can improve the communication guarantee capability in an emergency state.

[0067] The emergency communication device is set up to deal with the sudden situation underground that causes the side-following wireless communication base station device and the top wireless communication coverage device and other components to be physically damaged, resulting in communication obstruction. When the side-following wireless communication base station device and the top wireless communication coverage device are physically impacted, the mobile devices in the hands of the staff, such as Figure 2 The handheld communication terminal 104 cannot communicate with the ground server 102. At this time, the handheld communication terminal 104 uses a matching communication plug to insert into the communication socket 311 of the nearest communication socket 31. Through the emergency communication device, emergency communication can be achieved with the ground server 102 earlier, and the specific situation of the emergency on the ground can be informed as soon as possible, providing more accurate information for rescue.

[0068] Based on the matrix communication system of the ultra-large mining height fully mechanized mining working face of the present invention, the communication guarantee of the ultra-large mining height fully mechanized mining working face 103 is realized, including a normal wireless communication guarantee method and an emergency communication guarantee method.

[0069] Taking two communication equipment groups, two lateral slide slots 121, the track lengths of the lateral slide slots 121 of the moving device 12 and the electric linear guide rail 123 are both equal to 6 meters, the distance threshold is equal to 6 meters, and the initial distance is equal to 6 meters as an example, the normal wireless communication guarantee method is:
