The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] With the increasing mining depth and the influence of other factors such as over-excavation of slope foot and earthquake weathering, mines are facing a certain risk of slope instability. Slope landslide and collapse disasters pose a serious threat to the production safety of mines and the safety of life and property of personnel.

[0034] At present, in the process of mining operations, there is a huge difference in weight between transport vehicles and non-transport vehicles, and the corresponding safety distances are also different. When driving on a platform section, if the platform width of the platform section is large and the drivable road surface is wider, the driver cannot accurately know the current step slope angle and step height during driving, and it is easy to drive beyond the safe distance. The step slope stability outside the safety distance is poor, and collapse incidents are prone to occur, causing the vehicle to tip over to the ground below.

[0035] In response to the above problems, the embodiments of the present application provide a method and related device for processing vehicle trajectory information in a mining area, so as to determine the safe driving distance between the vehicle and the top line of the slope, and provide driving reminders to the user when the actual driving distance is less than the safe distance, thereby avoiding rollover accidents caused by the user's misjudgment of the safe driving distance in the mining area, and improving the safety of users driving in the mining area.

[0036] Please refer to Figure 1 , Figure 1 is a schematic diagram of the system architecture of a mining area management platform provided in an embodiment of the present application, such as Figure 1 The mining area management platform 100 shown includes: a Beidou watch 110, a server 120 and a communication box 130; wherein the Beidou watch 110 is connected to the server 120 for communication, and the Beidou watch 110 is connected to the communication box 130 for communication;

[0037] Among them, the communication box 130 is installed on the mining vehicle, integrating functional modules such as GPS, external communication interface, electronic processing unit, microcontroller, mobile communication unit and memory, providing network access, OTA (Over-The-Air, air download technology), remote control, location query / vehicle tracking and other functions, and can communicate with the Beidou watch 110; Beidou watch 110 is a smart watch based on the timing and positioning of China's Beidou satellite navigation system. Beidou watch 110 can receive Beidou satellite navigation system signals for timing; and Beidou watch 110 has a positioning function, can display latitude and longitude information, and comes with compass, altimeter and other functions. Specifically, Beidou watch 110 may include: a processing module, a storage module and a sending module. Among them, the processing module is used to identify the distress operation issued by the user in a trapped and distressed situation, such as pressing the distress button or sending a distress signal through the operating interface of the Beidou watch; the storage module is used to store the user's historical distress records to facilitate subsequent analysis of the user's search and rescue related data, such as search and rescue time, search and rescue effect, etc.; the sending module is used to generate a wireless signal to send a distress signal to the outside world based on the distress signal received by the processing module; the memory of the server 120 pre-stores mining area related information, including the geographical information of the mining area, the distribution trajectory of mining area roads, etc.

[0038] In an embodiment of the present application, the Beidou watch 110 first interacts with the communication box 130 through the near field communication mechanism NFC to obtain the identification information of the mining vehicle where the user is located, and then displays an inquiry message on the dial display screen of the Beidou watch 110 asking whether to turn on the mining driving assistance function. Then, a confirmation operation for the inquiry message is detected, and the following operations are performed: based on the identification information, the Beidou watch 110 interacts with the server 120 to obtain the weight information of the mining vehicle and the geographic information of the mining area to which the mining vehicle belongs, and the reference distance between the mining vehicle and the top line of the slope of the mining area is determined based on the positioning information of the Beidou watch 110 and the geographic information of the mining area. Finally, when it is monitored that the reference distance is less than or equal to the safety distance threshold under the weight information constraint condition, a prompt operation is performed to remind the user to adjust the reference distance.

[0039] The following describes a method for processing vehicle trajectory information in a mining area provided by an embodiment of the present application.

[0040] See also Figure 2 , Figure 2 is a collective flow chart of a method for processing vehicle trajectory information in a mining area provided by an embodiment of the present application, and the method is applied to Figure 1 The Beidou wristwatch 110 shown in the figure comprises the following steps:

[0041] Step S210, interacting with the communication box message through the near field communication mechanism NFC to obtain the identification information of the mining vehicle where the user is located.

[0042] Among them, Near Field Communication (NFC) is a contactless communication technology based on electromagnetic radio fields. It operates in the 13.56MHz frequency band and is a branch of RFID (radio frequency identification) technology. NFC technology is unique in its short distance and low bandwidth characteristics. NFC technology uses the principle of electromagnetic induction to establish point-to-point communication within a few centimeters. When two NFC devices are close to each other, a resonant circuit is formed between them, and they communicate through the electromagnetic field generated by inductive coupling, thereby exchanging information with each other, without the need to establish a physical connection between the devices to achieve data transmission.

[0043] In other possible examples, the Beidou watch and the communication box of the mining vehicle can establish a wireless communication link by establishing a Bluetooth connection, a Wi-Fi connection, a cellular network communication connection, or a low-power wide area network (LPWAN) technology such as Zigbee and LoRa.

[0044] Among them, the identification information is the unique identity identifier indicating the mining vehicle, and the parameter information of the corresponding mining vehicle, such as weight, body length, body width and other data, can be queried through the identification information.

[0045] Step S220, displaying a query message on the dial display screen of the Beidou wristwatch asking whether to enable the mining area driving assistance function.

[0046] Specifically, see Figure 3 , Figure 3 is a schematic diagram of an application interface of a Beidou wristwatch provided in an embodiment of the present application, such as Figure 3 As shown, it includes a display interface 300 of the Beidou wristwatch display screen, an inquiry message box 301 displayed on the display interface 300, a confirmation button 302 for confirming to enable the mining area driving assistance function, and a cancel button 303 for not confirming to enable the mining area driving assistance function.

[0047] Step S230, detecting a confirmation start operation for the inquiry message, and performing the following operations;

[0048] Specifically, the confirmation opening operation is an affirmative operation of the user in response to the inquiry message, which can be performed by clicking a finger, such as Figure 3 The confirmation button 302 in the display interface 300 of the Beidou watch display screen shown, or the user can reply to the inquiry message by inputting a voice message to the Beidou watch, the confirmation voice message is for example "confirm to turn on the driving assistance function".

[0049] Step S240: interact with the server message according to the identification information to obtain the weight information of the mining vehicle and the geographical information of the mining area to which the mining vehicle belongs.

[0050] Among them, the weight information includes the rated load and vehicle deadweight of the mining area vehicles. The geographic information of the mining area is used to characterize the geographical characteristics of the mining area, including the soil characteristics of the mining area and the terrain structure of the mining area. The terrain structure of the mining area includes the overall height and angle of the mining area slope, the width of the mining area platform section, the slope of the platform section and the height of the platform section.

[0051] Step S250, determining the reference distance between the mining area vehicle and the top line of the slope of the mining area according to the positioning information of the Beidou wristwatch and the geographical information of the mining area.

[0052] Specifically, see Figure 4 , Figure 4 It is a schematic diagram of a mining terrain provided in an embodiment of the present application, including a slope 410, a first slope top line 420, a second slope top line 460, a first mining vehicle 430, and a second mining vehicle 450, wherein the slope top line refers to the intersection line of the flat plate on the upper part of the step and the slope. If the mining vehicle is too close to the slope top line, the soil near the slope top line may collapse, causing the mining vehicle to slide down the slope 410; wherein, the reference distance between the first mining vehicle 430 and the first slope top line 420 is 440, and the reference distance between the second mining vehicle 450 and the second slope top line 460 is 450.

[0053] Among them, the current position of the vehicle in the mining area can be determined based on the positioning information, and the width of the road section at the current position can be determined based on the geographical information of the mining area, and then based on the vehicle's parameter information (the vehicle is assumed to be traveling in the middle of the road section), the reference distance = 1 / 2*(road section width-vehicle width) is determined.

[0054] Step S260, when it is monitored that the reference distance is less than or equal to the safety distance threshold under the weight information constraint condition, a prompt operation is performed to remind the user to adjust the reference distance.

[0055] In one possible example, the geographic information of the mining area includes at least one of the following: slope gradient and soil parameters; the safety distance threshold corresponding to a single weight information in the safety distance configuration set is determined by the following steps: the soil bearing capacity of the mining area is analyzed based on the soil parameters in the geographic information of the mining area, and the soil parameters include: soil density, soil water content and soil particle composition; the unit pressure of the mining area vehicle on the ground is determined based on the single weight information and the contact area of ​​the mining area vehicle; the safety distance threshold corresponding to the weight information is determined based on the slope gradient, soil bearing capacity and unit pressure, the soil bearing capacity is negatively correlated with the safety distance threshold, the unit pressure is positively correlated with the safety distance threshold, and the slope gradient is positively correlated with the safety distance threshold.

[0056] Specifically, the soil bearing capacity in the mining area can be understood as the maximum vertical load or shear strength that the soil can withstand per unit area; factors related to soil bearing capacity include: soil properties, the physical properties of the soil (such as density, internal friction angle, cohesion, etc.) and mechanical properties (such as elastic modulus, shear modulus, etc.) directly affect its bearing capacity, and the bearing capacity of different soil types (such as sand, clay, rock, etc.) is significantly different; water content, soil water content has a significant impact on bearing capacity. Overly wet soil may cause settlement or collapse due to reduced bearing capacity, while dry soil may increase the resistance of equipment operation due to lack of lubrication; groundwater level, the height of the groundwater level will also affect the bearing capacity of the soil, and a high groundwater level may lead to a decrease in the effective stress of the soil, thereby reducing its bearing capacity; topography, the topography of the mining area (such as slope, slope direction, rock outcropping, etc.) will also affect the bearing capacity of the soil. For example, a steep slope may increase the risk of soil slippage.

[0057] Among them, the slope gradient, soil bearing capacity, unit pressure and safety distance threshold satisfy the following formula:

[0058]

[0059] Among them, see Figure 5 , Figure 5 is a schematic diagram of another mining area terrain provided in an embodiment of the present application, L is a safety distance threshold, and the first slope top line 420 is as described above. Figure 4 As described above, θ is the slope gradient, Ps is the soil bearing capacity, and Pw is the unit pressure. The higher the Ps, the more capable the soil is of supporting or bearing buildings, roads, bridges and other engineering structures without damage or significant deformation. f(θ) is the tangent value of the slope with a gradient of θ. The larger the tangent value, the steeper the slope, and the greater the risk of accidents.

[0060] Among them, when the reference distance is less than or equal to the safety distance threshold, the step slope stability outside the safety distance is poor and is prone to collapse, causing vehicles in the mining area to tip over, posing a great driving risk.

[0061] It can be seen that in this example, the soil bearing capacity of the mining area is obtained by analyzing the soil parameters in the geographic information of the mining area; the unit pressure of the mining vehicle on the ground is determined based on the individual weight information and the contact area of ​​the mining vehicle; the safety distance threshold corresponding to the weight information is determined based on the slope gradient, soil bearing capacity and unit pressure. In this way, the reliability and accuracy of determining the safety distance threshold through weight information analysis are improved.

[0062] In a possible example, the prompt operation includes at least one of the following operations: a sound prompt operation, a vibration prompt operation, an electrical stimulation prompt operation, and an image prompt operation.

[0063] Specifically, see Figure 6 , Figure 6 is a schematic diagram of an application scenario of a prompt operation provided by an embodiment of the present application, such as Figure 6 As shown, Figure 1 The Beidou watch 110 in the embodiment can perform voice prompts 601, vibration prompts 602, electrical stimulation prompts 603, and image prompts 604. Among them, the voice prompts 601 can output prompt voices through the Beidou watch 110, for example: "It is currently detected that you are driving close to the slope, please pay attention to safety and drive inside", and the electrical stimulation prompts 603 are mainly through the stimulation electrodes and metal case electrodes connected by the smart chip signal of the watch head. When the smart chip detects that the reference distance of the mining vehicle driven by the user is less than the safety distance threshold, the watch head can control the stimulation electrodes and metal case electrodes to automatically send electric pulses to stimulate the user. The image prompts 604 are used to play warning animations or warning patterns on the display screen of the Beidou watch 110 to instruct the user to pay attention to controlling the driving distance and return to the safety distance threshold. Through a variety of prompt operations, users are reminded to pay attention to the safe driving distance in all directions, ensuring that users can perceive the prompt operations and improve user driving safety.

[0064] It can be seen that in this embodiment, the Beidou watch in the mining area management platform first interacts with the communication box message through the near field communication mechanism NFC to obtain the identification information of the mining area vehicle where the user is located. Secondly, the inquiry message of whether to turn on the mining area driving assistance function is displayed on the dial display screen of the Beidou watch. Then, the Beidou watch detects the confirmation and opening operation for the inquiry message, and performs the following operations: the Beidou watch interacts with the server message according to the identification information to obtain the weight information of the mining area vehicle and the geographical information of the mining area to which the mining area vehicle belongs. Then, the Beidou watch determines the reference distance between the mining area vehicle and the top line of the slope of the mining area according to the positioning information of the Beidou watch and the geographical information of the mining area. Finally, when the Beidou watch monitors that the reference distance is less than or equal to the safety distance threshold under the weight information constraint condition, the prompt operation is performed to remind the user to adjust the reference distance. In this way, the safe driving distance between the vehicle and the top line of the slope is accurately judged, accidents caused by the user's misjudgment of safe driving are avoided, and the safety of users driving in mining areas is improved.

[0065] In one possible example, the weight information of a mining vehicle and the geographic information of the mining area to which the mining vehicle belongs are acquired by interacting with a server message based on identification information, including: sending a query request message carrying identification information to a server, wherein the identification information is associated with the weight information of the mining vehicle and the geographic information of the mining area stored in the server; receiving a query response message from the server; and parsing the query response message to obtain the weight information and the geographic information.

[0066] Among them, the server includes the vehicle identification information and the weight information of the corresponding mining vehicle. After receiving the identification information sent by the Beidou watch, the server queries the corresponding mining vehicle weight information in the memory.

[0067] Specifically, the weight information includes the rated load and vehicle deadweight of the mining area vehicles. The geographic information of the mining area is used to characterize the geographical characteristics of the mining area, including the soil characteristics of the mining area and the terrain structure of the mining area. The terrain structure of the mining area includes the overall height and angle of the mining area slope, the width of the platform section of the mining area, the slope of the platform section and the height of the platform section.

[0068] It can be seen that in this example, a query request message carrying identification information is sent to the server, the identification information is associated with the weight information of the mining vehicle and the geographic information of the mining area stored in the server, a query response message from the server is received, and the query response message is parsed to obtain the weight information and geographic information. In this way, the mining vehicle is uniquely matched through the identification information, thereby avoiding deviations in the information obtained due to identification errors, improving accuracy and reliability, and further ensuring the safety of users' driving.

[0069] In one possible example, the reference distance between the mining area vehicle and the top line of the slope of the mining area is determined based on the positioning information of the Beidou watch and the geographic information of the mining area, including: predicting the reference driving trajectory of the mining area vehicle during the current monitoring period based on the positioning information of the Beidou watch; determining the shortest distance set between the reference driving trajectory and the slope of the mining area based on the geographic information of the mining area, the shortest distance set including the mapping relationship between the shortest distance between each sampling point in multiple sampling points and the slope of the mining area, and the multiple sampling points belong to the reference driving trajectory; obtaining the shortest reference distance with the smallest value in the shortest distance set, and using the shortest reference distance as the reference distance.

[0070] Specifically, the slope stability coefficient can be determined based on geographic information. Factors affecting the slope stability coefficient include: rock mass structure. The destruction of the slope rock mass is mainly controlled by the discontinuous surface (structural surface) in the rock mass. The rock mass structural factors that affect the stability of the slope mainly include the following aspects: the inclination and dip of the structural surface: the stability of the same-direction gentle slope (the inclination of the structural surface is consistent with the inclination of the slope surface, and the dip angle is less than the slope angle) is worse than that of the opposite slope. In the same-direction gentle slope, the steeper the inclination of the rock layer, the worse the stability; the stability of the horizontal rock layer is better; the direction of the structural surface. When the unfavorable structural surface is parallel to the slope surface, the entire slope surface has the condition of free sliding in the air, which is not conducive to the stability of the slope. The greater the angle between the structural surface and the slope surface, the more favorable it is to the stability of the slope; the number and quantity of structural surfaces. When the slope is cut by multiple sets of intersecting structural surfaces, the entire slope rock mass has a large room for free deformation, and there are many cutting surfaces, sliding surfaces and free surfaces, which are easy to form sliding blocks and provide better conditions for groundwater activities, which is not conducive to the stability of the slope. Secondly, the number of structural surfaces directly affects the size of the cut rock blocks, which not only affects the stability of the slope, but also affects the form of slope deformation and failure. Slopes with severely broken rock masses may even experience arc-shaped sliding failures similar to soil slopes.

[0071] It can be seen that in this example, by predicting the reference driving trajectory of the vehicle in the mining area and determining the reference distance, the accuracy and reliability of the estimated reference distance are improved, and the shortest reference distance is used as the reference distance to further protect the user's driving behavior.

[0072] In one possible example, a reference driving trajectory of a mining vehicle in a current monitoring period is predicted based on the positioning information of a Beidou watch, including: obtaining multiple positioning information of the Beidou watch at multiple sampling time points; determining a reference movement direction and driving speed of the mining vehicle based on the multiple positioning information; and determining a reference driving trajectory in the current monitoring period based on the reference movement direction, driving speed, and positioning information at the most recent sampling time point.

[0073] Specifically, see Figure 7 , Figure 7 is a navigation application schematic diagram of a Beidou wristwatch provided in an embodiment of the present application, such as Figure 7 As shown, after determining the reference driving trajectory, a navigation route 700 is planned and determined according to the predetermined starting point 701 and destination 702 of the mining vehicle, and the navigation route 700 includes a prompted mining slope section, wherein area 703 represents the slope surface, and area 704 represents the slope top line, and the user is prompted to ensure that the distance from area 704 reaches the safety distance threshold.

[0074] Specifically, the duration of the detection cycle is, for example, 1 second, and the duration of the sampling intervals of the multiple sampling points is 100 ms.

[0075] It can be seen that in this example, by obtaining multiple positioning information of the Beidou watch at multiple sampling time points, the reference movement direction and driving speed of the mining vehicle are determined according to the multiple positioning information, and the reference driving trajectory within the current monitoring period is determined according to the reference movement direction, driving speed and positioning information at the most recent sampling time point, thereby improving the reliability of determining the reference driving trajectory and improving the accuracy of the estimated driving trajectory.

[0076] In a possible example, the multiple sampling points include at least a starting point, an end point, and an intermediate position point of the reference driving trajectory.

[0077] In one possible example, before monitoring that the reference distance is less than or equal to the safety distance threshold under the weight information constraint, the method also includes: obtaining a pre-stored safety distance configuration set, the safety distance configuration set including a pre-created correspondence between the weight information of the mining vehicle and the safety distance threshold; using the weight information as a query mark, querying the safety distance configuration set, and obtaining the safety distance threshold corresponding to the weight information.

[0078] Specifically, after the safety distance threshold is queried, based on the above Figure 7 The navigation route 700 shown is displayed in real time according to the reference distance and the safety distance threshold of the mining area vehicle on the navigation route 700 to improve the user's perception of the safety distance threshold. Figure 8 , Figure 8 This is a schematic diagram of another navigation application of a Beidou watch provided in an embodiment of the present application. As shown in the figure, area 810 is a dangerous area formed by a real-time safety distance threshold determined according to the navigation route of the vehicle in the mining area. When a user drives into area 810, a prompt operation is performed to the user to remind the user that there is a driving risk at present and please drive on the inside.

[0079] Specifically, the Beidou watch can also send a query request to the server, and the query request is used to request the server to query the weight information of the mining vehicle indicated by the identification information, and the weight information includes the vehicle's own weight and rated load; according to the positioning information of the Beidou watch, the driving direction of the mining vehicle is determined, wherein the driving direction is associated with the weight information, and the association relationship is: the driving direction of the mining vehicle represents the mining vehicle from the loading area to the unloading area, then the weight information is equal to the sum of the rated load and the vehicle's own weight, and the loading area and the unloading area are the working areas in the mining area; the driving direction of the mining vehicle represents the mining vehicle from the unloading area to the loading area, then the weight information is determined to be the vehicle's own weight.

[0080] Among them, due to different driving directions, there may be deviations in weight information. For mining vehicles of transportable types, such as trucks and vans, the rated load is generally tens to hundreds of tons, which is very heavy and has a greater impact on the safety distance threshold. Therefore, the driving direction of the vehicle is considered to determine the purpose of the vehicle, whether it is to load or unload. If it is from the loading area to the unloading area, it represents the unloading purpose of the vehicle, and the weight information needs to consider the rated load. It is presumed that the cargo loaded on each vehicle is approximately equal to the rated load; similarly, if it is from the unloading area to the loading area, it represents the loading purpose of the vehicle, and the weight information only needs to consider the vehicle's own weight.

[0081] It can be seen that in this example, a pre-stored safety distance configuration set is obtained, and the safety distance configuration set includes the correspondence between the weight information of the mining vehicle and the safety distance threshold that is created in advance; the weight information is used as a query mark to query the safety distance configuration set, and the safety distance threshold corresponding to the weight information is obtained, so as to accurately judge the safe driving distance between the vehicle and the top line of the slope, thereby avoiding accidents caused by the user's misjudgment of safe driving and improving the safety of users' driving in mining areas.
