Description

Technical Field

[0001] The present invention relates to the technical field of mine air doors, and in particular to an intelligent air door height limit control method and system. Background Art

[0002] In the coal mine production process, the underground ventilation system is a vital component to ensure the safety of the mine. As a key device in the ventilation system, the damper is mainly used to control the direction and volume of the wind flow to ensure the air quality and safety inside the mine.

[0003] In the related technology, due to the different sizes of underground vehicles and equipment, if over-high or over-wide vehicles and equipment are forced through the damper, the damper may be damaged, or even cause wind turbulence and safety accidents. In addition, when a large number of underground transportation equipment needs to enter and exit the damper, the traditional damper relies on manual operation, which has the risk of misoperation, and easily leads to the risk of traffic jams at the entrance and exit of the damper. In addition, the traditional damper system lacks an effective information feedback mechanism, and it is impossible to grasp the passage status of the damper in time, making it difficult to achieve real-time monitoring and adjustment of underground transportation equipment. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0011] S4. Check the height of the vehicle again at the inlet of the air door;

[0012] S5. Control the air door to open and guide the vehicle to pass through the air door.

In this way, the monitoring and adjustment of underground vehicles are achieved.

[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figure 1 As shown, the intelligent air door height limit control method of the embodiment of the present invention includes the following steps:

[0036] S1. Establish a vehicle control system database, which includes the graphic data information of the underground tunnel 100, the data information of the damper 200, and the data information of the underground vehicle. It is understandable that the graphic data information of the underground tunnel 100 can be obtained by laser scanning surveying and mapping to obtain the precise graphic data of the tunnel 100, or a total station and underground GIS (geographic information system) can be used to survey the terrain of the tunnel 100 and establish a digital map of the tunnel 100. The data information of the damper 200 can be collected and uploaded to the database by sensors, cameras and Internet of Things technology. The underground vehicle data information can use GPS positioning to obtain the real-time location information of the vehicle, and use on-board sensors to obtain the speed, acceleration, angle and other sensors of the vehicle to monitor the running status of the vehicle, and use RFID tags installed on the vehicle to automatically identify and track through the underground RFID reader, and can also use the wireless communication equipment on the vehicle to realize the data transmission between the vehicle and the ground monitoring center.

[0037] In some embodiments, the intelligent damper height limit control method of the embodiment of the present invention also includes the following steps: in step S1, the underground tunnel 100 graphic data information includes the vehicle operation route, the damper 200 data information includes the damper 200 position information and the damper 200 passing height information and the damper 200 passing width information, and the underground vehicle data information includes vehicle ID information, vehicle position information and vehicle temporary height information.

[0038] It can be understood that the vehicle control system database can clearly understand the vehicle's running path in the underground tunnel 100, as well as determine the vehicle's own information and the damper 200 information, so as to facilitate the subsequent vehicle height limit detection and the implementation of issuing the vehicle's travel path.

[0039] S2, using the detection points between the vehicle starting position and the designated air door 200 inlet position to analyze and filter the vehicle information. Figure 1As shown, after loading goods or equipment, the vehicle in the underground tunnel 100 is marked from the starting position of the vehicle, and the vehicle's travel path is planned in advance using the vehicle control system database, and the vehicle information (i.e., vehicle height information) detected at each detection point on the travel path is collected, so as to perform real-time route planning based on the vehicle information.

[0040] In some embodiments, the intelligent throttle height limit control method of an embodiment of the present invention also includes the following steps: in step S2, multiple detection points are specified between the inlet positions of the throttle 200, and the multiple detection points are arranged at intervals on the vehicle operation route, and one detection point is electrically connected to multiple throttles 200.

[0041] It is understandable that if Figure 1 As shown, a detection point can be provided with multiple detection units 1, and each detection unit 1 can be provided with multiple detection devices, such as a height limit pole 122 device or an infrared measurement device, etc. That is to say, on the operation route of the vehicle, due to the ground of the lane 100, the shaking of the vehicle, etc., the detection data of the vehicle passing through the detection point fluctuates, so multiple detection points can be set in the lane 100 to improve the accuracy of vehicle information detection and avoid subsequent congestion in front of the damper 200 due to the height limit problem.

[0042] In some embodiments, in step S2, if the height and width of the vehicle do not meet the preset information of the detection point, the detection point sends a warning signal. Optionally, the warning signal includes at least one of sound, light and vibration.

[0043] It can be understood that when the vehicle passes through the detection point, the detection unit 1 can detect the height information of the vehicle and transmit the detection information to the vehicle control system database, and the vehicle control system database compares the detection information with the preset information of the corresponding air damper 200. If the detection information of the vehicle does not meet the preset information of the corresponding air damper 200, the vehicle control system database sends an instruction to start the warning signal to the detection unit 1 that detects the vehicle, so that the detection point sends a warning signal to remind the vehicle driver and collaborating personnel.

[0044] In addition, optionally, a light control system is also provided on the damper 200, that is, when the vehicle moves to the front side of the damper 200, the light control system on the damper 200 can be activated by using the vehicle's own light, so that the damper 200 can be controlled to open and close according to the command of the light control system. Therefore, when the detection information of the vehicle does not meet the preset information of the damper 200 corresponding to it, the vehicle control system database can send a self-locking command to the damper 200 to control the damper 200 to self-lock, so that the vehicle cannot use the light to open the door by light control, further avoiding the vehicle from passing through the damper 200 by mistake due to overheight, causing damage to the damper 200, and ensuring the stability of the ventilation system of the lane 100.

[0045] S3. If the height of the vehicle meets the preset height of the detection point, the graphic data information of the underground tunnel 100 and the data information of the damper 200 are used to guide the vehicle to the entrance of the designated damper 200. If the height of the vehicle does not meet the preset height of the detection point, the graphic data information of the underground tunnel 100 and the data information of the damper 200 are used to guide the vehicle to the entrance of other non-designated dampers 200 that meet the vehicle height.

[0046] It can be understood that when the height information detected by the vehicle does not meet the preset information of the corresponding (specified) damper 200, the vehicle control system database can send a signal to the other vehicles in the same batch as the vehicle that are carrying out transportation tasks, and plan a new operation route accordingly, so that the other vehicles in the same batch can adjust or change the transportation route in time, thereby reducing the possibility of congestion in front of the damper 200 in the alley 100.

[0047] In other words, the vehicle control system database can form an independent path judgment logic for the transfer path of the transport vehicles in the underground tunnel 100, so that the vehicle control system database can directly feedback the final route planning to the vehicles that exceed the height limit based on the vehicle detection information and the damper 200 information, thereby ensuring that the underground transport vehicles are reversed smoothly and reducing the impact on the ventilation system of the tunnel 100.

[0048] S4. Detect the height of the vehicle again at the inlet of the damper 200. It is understandable that the height of the vehicle is detected again at the inlet of the damper 200 using the detection unit 1 to further ensure that the height of the vehicle meets the preset height of the damper 200.

[0049] S5, control the damper 200 to open, and guide the vehicle to pass through the damper 200. It can be understood that the damper 200 is electrically connected to the vehicle control system database, so that the damper 200 can be opened accurately and precisely under the control of the vehicle control system database, avoiding damage to the damper 200 and other equipment caused by the super-high vehicle, and ensuring the smooth transportation of underground equipment.

[0050] In other words, the intelligent damper height limit control method of the embodiment of the present invention utilizes the established vehicle control system database to achieve real-time control of the running status of underground vehicles and the running status of dampers 200, so as to ensure that vehicles exceeding the height limit can be guided to other dampers 200 that meet their height limit in time, avoiding collisions between vehicles and dampers 200 and reducing the risk of traffic jams. In this way, monitoring and adjustment of underground vehicles are achieved.

[0051] Therefore, the intelligent air door height limit control method of the embodiment of the present invention is one of the ways to realize the intelligent construction of the tunnel 100 safety system, which makes the underground equipment transportation management more accurate, controllable and real-time. Its control form can also adapt to various tunnel 100 forms and can be promoted in various mine tunnels 100. At the same time, as an intelligent system management model, it also has great promotion and application value.

[0052] The following describes an intelligent air door height limit control system according to an embodiment of the present invention with reference to the accompanying drawings.

[0053] like Figure 2 and Figure 3 As shown, the intelligent damper height limit control system of an embodiment of the present invention, the intelligent damper 200 height limit control system is used to implement any of the intelligent damper 200 height limit control methods in the above embodiments, and the intelligent damper 200 height limit control system includes: an information control unit (not shown in the figure) and a detection unit 1.

[0054] The information control unit is used to receive, record and transmit the graphic data information of the underground tunnel 100, the data information of the damper 200 and the data information of the underground vehicle. The detection unit 1 is electrically connected to the information control unit. The detection unit 1 includes a first detection member 11 and a second detection member 12. The first detection member 11 is installed on the side wall of the tunnel 100, and the second detection member 12 is installed on the top wall of the tunnel 100. The second detection member 12 is arranged adjacent to the first detection member 11. There are multiple detection units 1, and the multiple detection units 1 are divided into the first detection unit 1 and the second detection unit 1. The multiple first detection units 1 are arranged adjacent to the damper 200 and correspond to the damper 200 one by one. The multiple second detection units 1 are arranged at intervals along the extension direction of the tunnel 100.

[0055] Specifically, Figure 2 and Figure 3 As shown, the graphic data information of the underground tunnel 100 can be obtained by laser scanning surveying and mapping to obtain accurate graphic data of the tunnel 100, or a total station and underground GIS (geographic information system) can be used to survey the terrain of the tunnel 100 and establish a digital map of the tunnel 100. The data information of the damper 200 can be collected by sensors, cameras and Internet of Things technology to collect real-time data of the damper 200 and upload it to the database. The data information of the underground vehicle can be obtained by GPS positioning to obtain the real-time location information of the vehicle, and the vehicle-mounted sensors can be used to obtain the speed, acceleration, angle and other sensors of the vehicle to monitor the running status of the vehicle. The RFID tags installed on the vehicle can be automatically identified and tracked by the underground RFID reader, and the wireless communication equipment on the vehicle can also be used to realize the data transmission between the vehicle and the ground monitoring center.

[0056] It is understandable that the first detection member 11 and the second detection member 12 can be different detection devices, and due to the different locations of the two, the accuracy of vehicle height detection can be improved. In addition, multiple detection units 1 are set in the lane 100, and multiple detections can be performed on the vehicle during transportation to further improve the accuracy of vehicle height detection.

[0057] Optionally, the first detection component 11 is an infrared measuring light curtain, and the second detection component 12 includes a mounting bracket 121 and a height limiting rod 122 , the mounting bracket 121 is connected to the top wall of the tunnel 100 , and the height limiting rod 122 is connected to the mounting bracket 121 and is movable relative to the mounting bracket 121 .

[0058] like Figure 2 and Figure 3 As shown, the upper end of the mounting bracket 121 is fixedly connected to the top wall of the alley 100, the extension direction of the height limit rod 122 is consistent with the width direction of the alley 100, and the height limit rod 122 can move up and down on the mounting bracket 121, so that the height of the height limit can be adjusted according to different use environments, so that the second detection component 12 has a wider range of application.

[0059] Optionally, the second detection member 12 further includes a height-limiting driving member, which is connected to the height-limiting rod 122 and is used to drive the height-limiting rod 122 to move. It is understandable that the height-limiting driving member can be a device with a linear reciprocating drive function, such as a linear module, a telescopic motor, or a device composed of a transmission mechanism such as a gear rack driven by a motor, so that the height-limiting rod 122 can be controlled to move up and down by controlling the start and stop of the height-limiting driving member.

[0060] In some embodiments, the second detection member 12 further includes a limiting member 123, which is connected to the mounting bracket 121 and is located at the bottom of the mounting bracket 121 to limit the movement of the height limiting rod 122. It is understandable that Figure 2 and Figure 3 As shown, the limiting member 123 is installed at the lower end of the mounting bracket 121 to limit the movement of the height limiting rod 122 to prevent the height limiting rod 122 from moving too long on the mounting bracket 121 and causing damage to the equipment.

[0061] In some embodiments, the intelligent throttle height limit control system of the embodiment of the present invention also includes a warning component, which is connected to at least one of the first detection component 11 and the second detection component 12, and the warning component is connected to the information control unit. When the first detection component 11 and / or the second detection component 12 detects that the vehicle information does not meet the preset information, the warning component sends a warning signal and transmits the warning information to the information control unit.

[0062] It can be understood that the warning member can be connected to the first detection member 11, or the warning member can be connected to the second detection member 12, or preferably, the warning member is connected to both the first detection member 11 and the second detection member 12, whereby when the warning member sends a warning signal, it can promptly remind the driver or collaborating personnel.

[0063] It should be noted that the warning signal includes at least one of sound, light and vibration.
