Description

Methods and related devices for processing vehicle trajectory information in mining areas Technical Field

[0001] This application relates to the field of mine safety monitoring technology, and in particular to a method and related device for processing vehicle trajectory information in a mining area. Background Technology

[0002] With the increasing depth of mining and the influence of other factors such as over-excavation of the slope toe and earthquake weathering, mines face certain risks of slope instability. Slope landslides and collapses pose a serious threat to the production safety of mines and the safety of people's lives and property.

[0003] Currently, during mining operations, there is a significant weight difference between transport vehicles and non-transport vehicles, resulting in different safety distances. When driving on platform sections, if the platform is wide and the driving surface is wide, the driver may easily drive beyond the safety distance because they cannot accurately know the slope angle and height of the current step. Beyond the safety distance, the slope stability of the step is poor, which can easily lead to collapse and cause the vehicle to tip over to the ground below. Summary of the Invention

[0004] This application provides a method and related apparatus for processing vehicle trajectory information in mining areas. By determining the safe driving distance between the vehicle and the top of the slope, and providing driving reminders to the user when the actual driving distance is less than the safe distance, this method avoids rollover accidents caused by the user's misjudgment of the safe driving distance in the mining area and improves the safety of users driving in the mining area.

[0005] In a first aspect, embodiments of this application provide a method for processing vehicle trajectory information in a mining area. The method is applied to a Beidou smartwatch in a mining area management platform, which includes a server, a Beidou smartwatch, and a communication box installed in the mining vehicles.

[0008] Upon detecting an enable action for the inquiry message, the following actions are performed:

[0009] The system interacts with the server based on the identification information to obtain the weight information of the mining vehicles and the geographical information of the mining area to which the vehicles belong.

[0010] The reference distance between the mining vehicle and the top of the slope in the mining area is determined based on the positioning information of the Beidou watch and the geographical information of the mining area.

[0011] When the reference distance is detected to be less than or equal to the safe distance threshold under the weight information constraint, a prompt action is executed to remind the user to adjust the reference distance.

[0012] Secondly, this application provides a device for processing vehicle trajectory information in a mining area, applied to a Beidou wristwatch in a mining area management platform.

The inquiry unit is used to display an inquiry message on the Beidou wristwatch's display screen asking whether to activate the mining area driving assistance function. The execution unit is used to detect a confirmation activation operation in response to the inquiry message and perform the following operations: The second acquisition unit is used to interact with the server based on the identification information to acquire the weight information of the mining vehicle and the geographical information of the mining area to which the vehicle belongs. The determination unit is used to determine the reference distance between the mining vehicle and the top of the slope in the mining area based on the positioning information of the Beidou wristwatch and the geographical information of the mining area. The prompting unit is used to perform a prompting operation when the reference distance is detected to be less than or equal to a safe distance threshold under the weight information constraint, to remind the user to adjust the reference distance.

[0016] As can be seen in this embodiment, the Beidou wristwatch in the mining area management platform first interacts with the communication box via NFC (Near Field Communication) to obtain the identification information of the vehicle in the mining area where the user is located.

Then, the Beidou wristwatch detects the confirmation operation in response to the inquiry message and performs the following operations: The Beidou wristwatch interacts with the server based on the identification information to obtain the weight information of the mining vehicle and the geographical information of the mining area to which the vehicle belongs. Next, the Beidou wristwatch determines the reference distance between the mining vehicle and the top of the slope in the mining area based on its own positioning information and the geographical information of the mining area. Finally, when the Beidou wristwatch detects that the reference distance is less than or equal to the safe distance threshold under the weight information constraint, it performs a prompt operation to remind the user to adjust the reference distance. In this way, the safe driving distance between the vehicle and the top of the slope is accurately determined, avoiding accidents caused by the user's misjudgment of safe driving and improving the user's driving safety in the mining area.

[0033] With the increasing depth of mining and the influence of other factors such as over-excavation of the slope toe and earthquake weathering, mines face certain risks of slope instability. Slope landslides and collapses pose a serious threat to the production safety of mines and the safety of people's lives and property.

[0034] Currently, during mining operations, there is a significant weight difference between transport vehicles and non-transport vehicles, resulting in different safety distances. When driving on platform sections, if the platform is wide and the driving surface is wide, the driver may easily drive beyond the safety distance because they cannot accurately know the slope angle and height of the current step. Beyond the safety distance, the slope stability of the step is poor, which can easily lead to collapse and cause the vehicle to tip over to the ground below.

[0035] To address the aforementioned issues, this application provides a method and related apparatus for processing vehicle trajectory information in mining areas. By determining the safe driving distance between the vehicle and the top of the slope, and providing driving reminders to the user when the actual driving distance is less than the safe distance, this method avoids rollover accidents caused by the user's misjudgment of the safe driving distance in mining areas, thereby improving the safety of users driving in mining areas.

[0036] Please refer to Figure 1 for details. Figure 1 is a schematic diagram of the system architecture of a mining area management platform provided in an embodiment of this application. As shown in Figure 1, the mining area management platform 100 includes: a Beidou wristwatch 110, a server 120, and a communication box 130; wherein, the Beidou wristwatch 110 is communicatively connected to the server 120, and the Beidou wristwatch 110 is communicatively connected to the communication box 130.

[0037] The communication box 130, installed on mining vehicles, integrates GPS, an external communication interface, an electronic processing unit, a microcontroller, a mobile communication unit, and a memory module. It provides network access, OTA (Over-The-Air) updates, remote control, location query / vehicle tracking, and other functions, and can communicate with the Beidou Watch 110. The Beidou Watch 110 is a smartwatch based on the Chinese Beidou Satellite Navigation System for timing and positioning. It can receive signals from the Beidou Satellite Navigation System for time synchronization and has positioning capabilities, displaying latitude and longitude information, and includes a compass and altimeter. Specifically, the Beidou Watch 110 may include a processing module, a storage module, and a transmission module. The processing module is used to identify the distress calls made by the user when trapped or in danger, such as pressing a distress button or sending a distress signal through the operation interface of the Beidou wristwatch; the storage module is used to store the user's historical distress call records for subsequent analysis of search and rescue related data, such as search and rescue time and results; the sending module is used to generate a wireless signal based on the distress signal received by the processing module and send the distress signal to the outside world; the server 120's memory pre-stores relevant information about the mining area, including the geographical information of the mining area and the distribution trajectory of roads in the mining area.

[0038] In this embodiment, the Beidou watch 110 first interacts with the communication box 130 via NFC to obtain the identification information of the vehicle in the mining area where the user is located. Then, an inquiry message asking whether to activate the mining area driving assistance function is displayed on the watch face of the Beidou watch 110. After detecting the confirmation operation in response to the inquiry message, 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 geographical information of the mining area to which the vehicle belongs. Based on the positioning information of the Beidou watch 110 and the geographical information of the mining area, the reference distance between the mining vehicle and the top of the slope in the mining area is determined. Finally, when the reference distance is less than or equal to the safe distance threshold under the weight information constraint, 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 this application.

[0040] Please refer to Figure 2, which is a schematic flowchart of a method for processing vehicle trajectory information in a mining area according to an embodiment of this application. The method is applied to the Beidou wristwatch 110 shown in Figure 1, and includes the following steps:

[0041] Step S210: Use the Near Field Communication (NFC) mechanism to interact with the communication box to obtain the identification information of the vehicle in the mining area where the user is located.

[0042] Near Field Communication (NFC) is a contactless communication technology based on electromagnetic radio fields. Operating in the 13.56MHz frequency band, it is a branch of RFID (Radio Frequency Identification) technology. NFC technology is characterized by its unique short-range and low-bandwidth characteristics. NFC utilizes the principle of electromagnetic induction to establish point-to-point communication within a few centimeters. When two NFC devices are close together, a resonant circuit is formed between them, communicating through the electromagnetic field generated by inductive coupling, thereby exchanging information without requiring a physical connection between the devices to achieve data transmission.

[0043] In other possible examples, the communication box between the Beidou wristwatch and the mining vehicle can establish a wireless communication link through technologies such as Bluetooth, Wi-Fi, cellular network, or low-power wide-area network (LPWAN) such as Zigbee and LoRa.

[0044] The identification information is a unique identifier for vehicles in the mining area. The corresponding parameters of the mining vehicle, such as weight, body length, and body width, can be retrieved through the identification information.

[0045] Step S220: Display a message on the dial screen of the Beidou watch asking whether to activate the mining area driving assistance function.

[0046] Specifically, please refer to Figure 3. Figure 3 is a schematic diagram of the application interface of a Beidou wristwatch provided in an embodiment of this application. As shown in Figure 3, 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 the activation of the mining area driving assistance function, and a cancel button 303 for not confirming the activation of the mining area driving assistance function.

[0047] Step S230: Upon detecting a confirmation activation operation for the query message, the following operations are performed;

[0048] Specifically, the confirmation operation is a positive action taken by the user in response to the inquiry message. It can be done by tapping the confirmation button 302 on the display interface 300 of the Beidou watch screen as shown in Figure 3, or by the user replying to the inquiry message by inputting voice information into the Beidou watch, such as "Confirm activation of driving assistance function".

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

[0050] The weight information includes the rated load capacity and vehicle weight of vehicles in the mining area. The geographical information of the mining area is used to characterize the geographical features of the mining area, including the soil properties and topographic structure of the mining area. The topographic structure of the mining area includes the overall height and angle of the slopes of the mining area, the width of the platform road section, the slope of the platform road section, and the height of the platform road section.

[0051] Step S250: Determine the reference distance between the mining vehicle and the top of the slope in the mining area based on the positioning information of the Beidou watch and the geographical information of the mining area.

[0052] Specifically, please refer to Figure 4, which is a schematic diagram of a mining area terrain provided in an embodiment of this application, including a slope 410, a first slope crest line 420, a second slope crest line 460, a first mining vehicle 430, and a second mining vehicle 450. The slope crest line refers to the intersection of the upper flat plate of the step and the slope. If the mining vehicle is too close to the slope crest line, the soil near the slope crest line may collapse, causing the mining vehicle to slide down the slope 410. The reference distance between the first mining vehicle 430 and the first slope crest line 420 is 440, and the reference distance between the second mining vehicle 450 and the second slope crest line 460 is 450.

[0053] The system can determine the current location of vehicles traveling in the mining area based on the location information, thereby determining the road width at the current location based on the geographical information of the mining area, and then determining the reference distance = 1 / 2 * (road width - vehicle width) based on the vehicle's parameter information (assuming the vehicle is traveling in the middle of the road segment).

[0054] In step S260, when the reference distance is detected to be less than or equal to the safe distance threshold under the weight information constraint, a prompting 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: based on the soil parameters in the geographic information of the mining area, the soil bearing capacity of the mining area is analyzed, and the soil parameters include: soil density, soil moisture content, and soil particle composition; based on the single weight information and the contact area of ​​the mining area vehicles, the unit pressure of the mining area vehicles on the ground is determined; based on the slope gradient, soil bearing capacity, and unit pressure, the safety distance threshold corresponding to the weight information is determined, where soil bearing capacity is inversely correlated with the safety distance threshold, unit pressure is positively correlated with the safety distance threshold, and slope gradient is positively correlated with the safety distance threshold.

[0056] Specifically, soil bearing capacity in mining areas can be understood as the maximum vertical load or shear strength that soil can withstand per unit area. Factors related to soil bearing capacity include: soil properties, where the physical properties (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.) varies significantly; water content, which has a significant impact on bearing capacity. Excessively wet soil may lead to settlement or collapse due to reduced bearing capacity, while dry soil may increase the resistance to equipment operation due to lack of lubrication; groundwater level, which also affects soil bearing capacity, as a high groundwater level may lead to a reduction in effective soil stress, thereby reducing its bearing capacity; and topography, where the topography of the mining area (such as slope, aspect, rock outcrops, etc.) also affects soil bearing capacity. For example, steep slopes may increase the risk of soil slippage.

[0057] The slope gradient, soil bearing capacity, unit pressure, and safe distance threshold satisfy the following formula:

[0058]

[0059] Please refer to Figure 5, which is a schematic diagram of another mining area terrain provided in the embodiment of this application. L is the safety distance threshold, the first slope crest line 420 is as described in Figure 4 above, θ is the slope gradient, Ps is the soil bearing capacity, and Pw is the unit pressure. The higher Ps is, the more capable the soil is of supporting or bearing engineering structures such as buildings, roads, and bridges without damage or significant deformation. f(θ) is the tangent value of the slope gradient θ. The larger the tangent value is, the steeper the slope is, and the greater the risk of accident.

[0060] Among them, when the reference distance is less than or equal to the safety distance threshold, the stability of the step slope outside the safety distance is poor, and it is prone to collapse, which can cause mining vehicles to tip over and pose a great driving risk.

[0061] As can be seen in this example, the soil bearing capacity of the mining area is obtained by analyzing the soil parameters in the geographical 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; and the safe 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 safe distance threshold through weight information analysis are improved.

[0062] In one possible example, the cueing action includes at least one of the following: sound cueing action, vibration cueing action, electrical stimulation cueing action, and image cueing action.

[0063] Specifically, please refer to Figure 6, which is a schematic diagram of an application scenario for a prompting operation provided in an embodiment of this application. As shown in Figure 6, the Beidou wristwatch 110 in Figure 1 can execute sound prompts 601, vibration prompts 602, electrical stimulation prompts 603, and image prompts 604. Sound prompts 601 can output prompt voice messages through the Beidou wristwatch 110, such as: "Currently, it has been detected that your driving distance is close to the slope. Please pay attention to safety and drive closer to the inside." Electrical stimulation prompts 603 are mainly achieved through the stimulation electrodes and metal case electrodes connected to the smart chip in the watch head. When the smart chip detects that the reference distance of the user's driving vehicle in the mining area is less than the safe distance threshold, the watch head can control the stimulation electrodes and metal case electrodes to automatically send electrical pulses to stimulate the user. Image prompts 604 are used to play warning animations or warning patterns on the display screen of the Beidou wristwatch 110 to instruct the user to pay attention to controlling the driving distance and return to within the safe distance threshold. Through multiple prompting operations, the user is comprehensively reminded to pay attention to the safe driving distance, ensuring that the user can perceive the prompting operations and improving user driving safety.

[0064] As can be seen, in this embodiment, the Beidou wristwatch in the mining area management platform first interacts with the communication box via Near Field Communication (NFC) to obtain the identification information of the vehicle in the mining area where the user is located. Next, a message asking whether to activate the mining area driving assistance function is displayed on the Beidou wristwatch's screen. Then, the Beidou wristwatch detects the confirmation operation in response to the message and performs the following operations: The Beidou wristwatch interacts with the server based on the identification information to obtain the weight information of the mining vehicle and the geographical information of the mining area to which the vehicle belongs. Next, the Beidou wristwatch determines the reference distance between the mining vehicle and the top of the slope in the mining area based on its own positioning information and the geographical information of the mining area. Finally, when the Beidou wristwatch detects that the reference distance is less than or equal to the safe distance threshold under the weight information constraint, it performs a prompt operation to remind the user to adjust the reference distance. In this way, the safe driving distance between the vehicle and the top of the slope is accurately determined, avoiding accidents caused by the user's misjudgment of safe driving and improving the user's driving safety in the mining area.

[0065] In one possible example, the process of interacting with the server based on identification information to obtain the weight information of the mining vehicles and the geographical information of the mining area to which the vehicles belong includes: sending a query request message carrying identification information to the server, wherein the identification information is associated with the weight information of the mining vehicles and the geographical 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 geographical information.

[0066] The server contains vehicle identification information and corresponding weight information for vehicles in the mining area. After receiving the identification information sent by the Beidou wristwatch, the server queries the corresponding weight information for vehicles in the mining area from its memory.

[0067] Specifically, the weight information includes the rated load capacity and vehicle weight of the mining area vehicles, and the geographical information of the mining area is used to characterize the geographical characteristics of the mining area, including the soil properties and topographic structure of the mining area. The topographic structure of the mining area includes the overall height and angle of the mining area slopes, the width of the mining area platform road sections, the slope of the platform road sections, and the height of the platform road sections.

[0068] As can be seen in this example, by sending a query request message carrying identification information to the server, the identification information is associated with the weight information of the mining vehicle and the geographical information of the mining area stored in the server. The query response message is received from the server, and the weight information and geographical information are obtained by parsing the query response message. In this way, the identification information uniquely corresponds to the mining vehicle, avoiding the deviation of the information obtained due to identification errors, improving accuracy and reliability, and thus further ensuring the safety of the user's driving.

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

[0070] Specifically, the slope stability coefficient can be determined based on geographical information. Factors affecting the slope stability coefficient include: rock mass structure. The failure of the rock mass is mainly controlled by discontinuities (structural planes) within the rock mass. The rock mass structure factors affecting slope stability mainly include the following aspects: the dip and angle of the structural planes: Slopes with gentle dips in the same direction (where the dip of the structural plane is consistent with the slope surface dip, and the dip angle is less than the slope angle) have better stability than slopes with opposite dips. In gentle dips in the same direction, the steeper the dip angle of the rock strata, the worse the stability; horizontal rock strata have better stability. The orientation of the structural planes: when the orientation of an unfavorable structural plane is parallel to the slope surface, the entire slope surface has the condition for free sliding, which is detrimental to slope stability. The larger the angle between the orientation of the structural plane and the slope orientation, the more favorable it is for slope stability. The number and variety of structural planes also play a role. When a slope is cut by multiple intersecting structural planes, the entire slope rock mass has greater room for free deformation, resulting in more cutting surfaces, sliding surfaces, and free surfaces. This makes it easier to form sliding blocks and provides favorable conditions for groundwater activity, which is detrimental to slope stability. Secondly, the number of structural planes directly affects the size of the cut rock blocks, influencing not only slope stability but also the form of slope deformation and failure. Slopes with severely fractured rock masses may even exhibit arc-shaped sliding failures similar to those seen in soil slopes.

[0071] As can be seen, in this example, by predicting the reference driving trajectory of vehicles in the mining area and determining the reference distance, the accuracy and reliability of the estimated reference distance are improved. Using the shortest reference distance as the reference distance further protects the user's driving behavior.

[0072] In one possible example, predicting the reference driving trajectory of mining vehicles within the current monitoring period based on the positioning information of the Beidou wristwatch includes: acquiring multiple positioning information of the Beidou wristwatch at multiple sampling time points; determining the reference direction of motion and driving speed of the mining vehicles based on the multiple positioning information; and determining the reference driving trajectory within the current monitoring period based on the reference direction of motion, driving speed, and positioning information of the most recent sampling time point.

[0073] Specifically, please refer to Figure 7, which is a schematic diagram of a navigation application of a Beidou wristwatch provided in an embodiment of this application. As shown in Figure 7, after determining the reference driving trajectory, a navigation route 700 is planned and determined according to the pre-determined starting point 701 and destination 702 of the mining vehicle. The navigation route 700 includes a mining area slope section that is indicated. Region 703 represents the slope surface, and region 704 represents the slope crest line. The user is prompted to ensure that the distance from region 704 reaches a safe distance threshold.

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

[0075] As can be seen, in this example, by acquiring multiple positioning information from the Beidou wristwatch at multiple sampling time points, the reference direction of motion and driving speed of the mining vehicle are determined based on the multiple positioning information. Based on the reference direction of motion, driving speed, and positioning information from the most recent sampling time point, the reference driving trajectory within the current monitoring period is determined, which improves the reliability of determining the reference driving trajectory and the accuracy of predicting the driving trajectory.

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

[0077] In one possible example, before detecting that the reference distance is less than or equal to the safe distance threshold under the weight information constraint, the method further includes: obtaining a pre-stored safe distance configuration set, which includes a pre-created correspondence between the weight information of mining vehicles and the safe distance threshold; querying the safe distance configuration set using the weight information as a query flag to obtain the safe distance threshold corresponding to the weight information.

[0078] Specifically, after querying the safe distance threshold, based on the navigation route 700 shown in Figure 7, the reference distance and safe distance threshold of the mining area vehicles are displayed in real time on the navigation route 700 to improve the user's perception of the safe distance threshold. Please refer to Figure 8, which is a schematic diagram of another navigation application of Beidou wristwatch provided in this application embodiment. As shown in the figure, area 810 is a dangerous area formed by the real-time safe distance threshold determined according to the navigation route of the mining area vehicles. When the user drives into area 810, the user is prompted to drive closer to the inside of the road due to the current driving risk.

[0079] Specifically, the Beidou wristwatch can also send query requests to the server. These requests are used to request the server to retrieve the weight information of the mining vehicles indicated by the identification information. The weight information includes the vehicle's tare weight and rated load. Based on the Beidou wristwatch's positioning information, the driving direction of the mining vehicles is determined. The driving direction is related to the weight information. The relationship is as follows: if the driving direction of the mining vehicles indicates that the vehicles are moving 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 tare weight. The loading area and the unloading area are the working areas in the mining area. If the driving direction of the mining vehicles indicates that the vehicles are moving from the unloading area to the loading area, then the weight information is determined to be the vehicle's tare weight.

[0080] Due to different travel directions, there may be deviations in weight information. For transportable mining vehicles, such as trucks and lorries, the rated load is generally tens to hundreds of tons, which is very heavy and has a significant impact on the safety distance threshold. Therefore, the purpose of the vehicle's journey should be determined by considering the vehicle's travel direction, whether it is to load or unload. If it is from the loading area to the unloading area, it represents the vehicle's unloading purpose, and the weight information needs to take into account the rated load, assuming 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 vehicle's loading purpose, and the weight information only needs to consider the vehicle's own weight.

[0081] As can be seen in this example, a pre-stored set of safe distance configurations is obtained. This set includes the correspondence between the weight information of mining vehicles and the safe distance thresholds. Using the weight information as the query flag, the safe distance configuration set is queried to obtain the safe distance threshold corresponding to the weight information. This accurately determines the safe driving distance between the vehicle and the crest line, avoiding accidents caused by the user's misjudgment of safe driving and improving the user's driving safety in the mining area.

[0089] In one possible example, multiple sampling points include at least the start point, end point, and intermediate position points of the reference driving trajectory.

[0090] In one possible example, before detecting that the reference distance is less than or equal to the safe distance threshold under the weight information constraint, the prompting unit 960 is further configured to: obtain a pre-stored safe distance configuration set, which includes a pre-created correspondence between the weight information of mining vehicles and the safe distance threshold; query the safe distance configuration set using the weight information as a query flag, and obtain the safe distance threshold corresponding to the weight information.
