Detailed Implementation

[0019] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.

[0022] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the structure of an integrated device for safety monitoring and dispatching of mining vehicles in a material yard, as shown in an exemplary embodiment of this application. (Reference) Figure 1 It can be seen that the integrated device for safety monitoring and dispatching of mining vehicles in this material yard may include: 110 mining vehicles and 120 dispatch center.

[0023] In tunnel construction or other large-scale engineering projects, where large quantities of stone, aggregate, or backfill materials are required, multiple temporary quarries can be set up along the project route to meet the needs. Since quarry location 210 and unloading location 220 need to fulfill different functions, and to avoid interference between operations at quarry location 210 and unloading location 220, unloading location 220 can be set up at a predetermined distance from quarry location 210. The transport vehicle 112 can be a heavy-duty dump truck, with a tare weight reaching tens or even hundreds of tons. Such overweight vehicles can cause serious damage to the asphalt pavement of ordinary urban roads. Furthermore, quarry location 210 and unloading location 220 are generally located on the outskirts of cities where urban roads are scarce; therefore, the transport route 230 is generally a temporary road. Because transport vehicle 112 may experience bumps while traveling on transport route 230, stones may fall from the truck bed. Falling stones could prevent transport vehicle 112 from passing smoothly. Therefore, it is necessary to monitor for falling stones from transport vehicle 112. If transport vehicle 112 detects falling stones, it should promptly report to dispatch center 120. Dispatch center 120 will then dispatch mining vehicle 110 to ensure the smooth transport by transport vehicle 112. Transport route 230 typically includes a two-way passage, that is... Figure 1 The two dashed lines shown represent the distance from quarry position 210 to unloading position 220 and from unloading position 220 to quarry position 210, respectively. When large stones fall, they may land in one direction of the passage. The transport vehicle 112 can use the passage in the other direction to continue driving. However, if a vehicle comes from the opposite direction during the use of the passage, the transport vehicle 112 in the opposite direction needs to slow down or stop, which affects the transport efficiency.

[0024] The mining vehicle 110 includes a quarrying vehicle 111 and a transport vehicle 112. The quarrying vehicle 111 is used to quarry stone and place the stone in the truck bed of the transport vehicle 112. The transport vehicle 112 is used to transport the stone from the quarrying position 210 to the unloading position 220 along the transport path 230.

[0025] Quarry vehicle 111 can operate at quarry location 210, which can be a quarry. Quarry vehicle 111 can be operated by personnel or automatically. Quarry vehicle 111 extracts stone at quarry location 210 and loads the extracted stone into the cargo bed of transport vehicle 112. After the cargo bed of transport vehicle 112 meets the preset transportation requirements, transport vehicle 112 can transport the stone from quarry location 210 to unloading location 220 along transportation path 230. Transport vehicle 112 can be operated by personnel or automatically.

[0026] Please see Figure 2 This is a schematic diagram of the structure of a transport vehicle shown in an exemplary embodiment of this application. The transport vehicle 112 may include a first communication system 112A and a rockfall detection system 112B. The rockfall detection system 112B may include a through-beam photoelectric switch 112B1 disposed on the side of the truck bed of the transport vehicle 112. In response to detecting that a rock is blocking the light emitted by the through-beam photoelectric switch 112B1, the rockfall detection system 112B generates first rockfall information and sends the rockfall information to the dispatch center 120 through the first communication system 112A.

[0027] The through-beam photoelectric switch 112B1 can be installed on three sides of the transport vehicle 112, and the three sides can be the three sides furthest away from the transport vehicle 112. Figure 2 (The diagram shown is a schematic of a single side). The through-beam photoelectric switch 112B1 is a detection device 112B2 that outputs light through a transmitter and receives the light directly through a receiver. When an object blocks the light, a switch signal is triggered. In this embodiment, after the switch signal is triggered, the rockfall detection system 112B can generate first rockfall information. The first rockfall information may include the position of the transport vehicle 112 when the photoelectric switch signal is triggered and the presence of a rockfall at that position.

[0028] Optionally, the transmitter and receiver of the through-beam photoelectric switch 112B1 can be respectively located at opposite ends of the same side of the truck bed. The through-beam photoelectric switch 112B1 can be housed within a protective cover to ensure its sensitivity in dusty environments.

[0029] Optionally, the rockfall detection system 112B may further include a detection device 112B2, which may be mounted on the top of the transport vehicle 112. The detection device 112B2 is used to acquire second rockfall information. The rockfall detection system 112B is also used to upload the second rockfall information to the dispatch center 120 via the first communication system 112A. In response to the generation of first rockfall information by the rockfall detection system 112B, the detection device 112B2 is activated. The dispatch center 120 is used to generate dispatch information based on the second rockfall information and the first rockfall information.

[0030] After receiving the first and second rockfall information, the dispatch center 120 can verify the first rockfall information based on the second rockfall information. That is, when the through-beam photoelectric switch 112B1 detects that stones have fallen from the transport vehicle 112, there may be false detections or small stones falling. When small stones fall, their impact on the operation of the transport vehicle 112 is small and no action is required. Therefore, the first rockfall information can be verified by the second rockfall information to determine whether large stones that affect the operation of the transport vehicle 112 have fallen from the truck bed of the transport vehicle 112.

[0031] Optionally, the detection device 112B2 may include a camera and / or radar. The data acquisition surface of the camera and / or radar may face the truck bed.

[0032] For example, the detection device 112B2 can be installed on the roof of the transport vehicle 112. When the detection device 112B2 includes a camera, the camera's field of view can include the truck bed and the transport path 230 behind the direction of travel of the transport vehicle 112. The camera can capture an image to be identified, and the second rockfall information can include the image to be identified. The rockfall detection system 112B can upload the image to be identified captured by the camera to the dispatch center 120 through the first communication system 112A. Radar is an electronic device that can use electromagnetic waves to detect, locate, and identify targets. Radar can emit a cone-shaped beam, which reflects back after hitting an object and is received by a receiver, thus detecting the object. When the detection device 112B2 includes radar, the radar can emit a laser towards the truck bed to detect the area including the truck bed. If a rockfall is encountered, first detection information can be obtained; if no rockfall is encountered, second detection information can be obtained. The second rockfall information can include either the first or the second detection information.

[0033] Optionally, the transport vehicle 112 may also be equipped with a positioning device to determine the location of the transport vehicle 112, and may also be equipped with a display and a walkie-talkie to display and respond to relevant instructions from the dispatch center 120. The transport vehicle 112 may also be equipped with an on-board computer to process data at the transport vehicle 112 end.

[0034] Optionally, the quarry vehicle 111 may include a second communication system. The quarry vehicle 111 can receive dispatch information sent by the dispatch center 120 through the second communication system, and after receiving the dispatch information, go to the location of the fallen rock and remove the fallen rock from the transport path 230.

[0035] Please see Figure 3 This is a schematic diagram illustrating the structure of an integrated device for safety monitoring and dispatching of mining vehicles in a material yard, as shown in another exemplary embodiment of this application. The transport vehicle 112 is also used to travel from the unloading position 220 to the quarrying position 210 along a backup path 240 after receiving dispatch information.

[0036] It should be noted that the dispatch information may be used only to instruct quarry vehicle 111 to work, or it may be used only to instruct transport vehicle 112 to work, or it may instruct both quarry vehicle 111 and transport vehicle 112 to work simultaneously. When the dispatch information only instructs quarry vehicle 111 to work, the dispatch information may only include information instructing quarry vehicle 111 to proceed to the rockfall location to remove the fallen stones from the transport path 230; when the dispatch information only instructs transport vehicle 112 to work, the dispatch information may only include information instructing transport vehicle 112 to proceed from unloading location 220 to quarry location 210 along the alternative path 240; when the dispatch information instructs both quarry vehicle 111 and transport vehicle 112 to work simultaneously, the dispatch information may include information instructing quarry vehicle 111 to proceed to the rockfall location to remove the fallen stones from the transport path 230, and information instructing transport vehicle 112 to proceed from unloading location 220 to quarry location 210 along the alternative path 240.

[0037] When dispatching quarry vehicle 111, there may be no available quarry vehicle 111. In this case, the stones that have fallen onto transport path 230 cannot be removed in time. In addition, if quarry vehicle 111 arrives at the rockfall location later than transport vehicle 112, it will affect the smooth passage of transport vehicle 112. In this case, the dispatch information can simultaneously instruct quarry vehicle 111 and transport vehicle 112 to work. When transport vehicles 112 traveling in different directions on transport path 230 do not arrive at the rockfall location at the same time, the dispatch information can instruct only quarry vehicle 111 or transport vehicle 112 to work.

[0038] The integrated safety monitoring and dispatching device for the quarry vehicle 110 also includes a first weighing device 130 located at the exit of the quarry location 210 and a second weighing device 140 located at the entrance of the unloading location 220. The first weighing device 130 is used to collect the first weight of the transport vehicle 112 and upload the first weight to the dispatching center 120 through the communication system. The second weighing device 140 is used to collect the second weight of the transport vehicle 112 and upload the second weight to the dispatching center 120 through the communication system. The dispatching center 120 generates third rockfall information when the difference between the first weight and the second weight is greater than the difference threshold.

[0039] When the through-beam photoelectric switch 112B1 is not triggered, there may be large pieces of fallen stone that have not been detected. At this time, the difference between the first weight when the transport vehicle 112 departs and the second weight when the transport vehicle 112 ends can be detected to determine whether the difference between the two weights is greater than the difference threshold. The difference threshold can be set to take into account the weight of the large pieces of stone that affect the passage of the vehicle. The specific setting can be made by the operator according to the actual situation.

[0040] Optionally, the integrated safety monitoring and dispatching device for the material yard mining vehicle 110 also includes a drone 150; the dispatching center 120 is also used to generate control commands for the drone 150 in response to the generation of third rockfall information, and send the control commands to the drone 150; the drone 150 is used to go to the transport path 230 for inspection after receiving the control commands.

[0041] Optionally, the drone 150 is pre-parked at a drone parking location 160 near the transport path 230.

[0042] Optionally, the dispatch center 120 is also used to receive images of the transport path 230 sent by the drone 150, generate fourth rockfall information when there are stones on the transport path 230, and generate dispatch information based on the fourth rockfall information. The dispatch center 120 can perform image processing on the images of the transport path 230 sent by the drone 150 to identify whether there are fallen stones on the transport path 230, and if there are fallen stones, determine the location of the fallen stones based on the position when the drone 150 acquires the image, and then generate fourth rockfall information.

[0043] The drone 150 can be pre-parked at a drone parking position 160 near the transport path 230, which can be set by the operator. After generating the third rockfall information, it can be determined that there are large rocks falling on the transport path 230. At this time, a control command for the drone 150 can be generated and sent to the drone 150. After receiving the control command, the drone 150 can proceed to the transport path 230 for inspection based on the preset flight inspection path.

[0044] Optionally, the dispatch center 120 can generate a search instruction based on the third rockfall information and send the search instruction to the transport vehicle 112 through the first communication system 112A, so that the transport vehicle 112 can display the search instruction and receive the search information fed back by the user. The search information may include the location of the rockfall. The dispatch center 120 can also generate dispatch information based on the search information.
