[0024] In order to better understand the above technical scheme, the technical scheme of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0025] The following is a further detailed description of a method for generating an electronic fence for a spoil dump provided by an embodiment of the present application in conjunction with the accompanying drawings. The specific implementation of the method may include the following steps (the method flow is as follows: Figure 1 shown):

[0026] Step 101, construct an initial dumping ground electronic fence, and record in real time the information of the muck trucks entering the initial dumping ground electronic fence, wherein the information includes the time information of entering and leaving the initial dumping ground electronic fence and the vehicle information.

[0027] In the solution provided in the embodiment of the present application, as a possible implementation method, an initial electronic fence of the spoil dump is constructed, including: constructing a plane model of the spoil dump with multiple layers of steps, marking the position and elevation information of each layer on the plane model; and constructing a virtual geographic boundary on the plane model according to preset spoil dump design parameters to obtain the initial electronic fence of the spoil dump.

[0028] As an example, in the solution provided in the embodiment of the present application, a plane electronic model of a spoil dump with multiple high and low steps is first constructed, and then the position and elevation information of each layer of steps are marked on the plane model. Then, according to the planning and design parameters of the spoil dump, a virtual geographic boundary is constructed on the plane electronic model to obtain the initial spoil dump electronic fence. Figure 2 A schematic diagram of an initial spoil dump electronic fence provided in an embodiment of the present application, wherein: Figure 2 The "first dumping ground" refers to the "initial dumping ground" mentioned here.

[0029] Furthermore, there will be muck trucks driving in and / or out of the dump site from time to time. As the muck trucks are dumping in the dump site, the positions and elevation information of each layer of the dump site will change, and the position of the actual edge retaining wall of the dump site will change. In other words, the position of the actual edge retaining wall of the dump site changes dynamically, and the change in the position of the actual edge retaining wall of the dump site will affect the safety of the operators and vehicles. Only when the operators know the position of the retaining wall in time can the occurrence of unsafe incidents be avoided. Therefore, in order to enable the operators to know the position of the retaining wall in time, it is necessary to record the information of the muck trucks driving into the initial dump site electronic fence in real time. As an example, the information includes but is not limited to the time information of the muck trucks driving in and out of the initial dump site electronic fence, vehicle information (such as vehicle ID or number), the longitude, latitude and elevation information of the vehicle, etc.

[0030] As another example, see Figure 3, a vehicle-mounted positioning device (such as a high-precision vehicle-mounted positioning device) is installed on the muck truck. The muck truck uses the vehicle-mounted positioning device to locate the real-time position of the muck truck during driving (for example, longitude, latitude or elevation information), and determines the corresponding track point according to the real-time position, and uses the geographic fence algorithm to perform real-time analysis on each track point to determine whether it is located within the initial dumping ground electronic fence. For example, the ray method is used to determine whether the track point falls within the polygon corresponding to the initial dumping ground electronic fence. If it is detected that the muck truck has a track point located within the initial dumping ground electronic fence, it means that the muck truck has entered the initial dumping ground electronic fence, and the time when the track point is first collected to be located within the initial dumping ground electronic fence (i.e., the entry time), vehicle ID, longitude, latitude, and elevation information, etc. are recorded. If the track points of the muck truck running in a certain period of time are detected to be inside the electronic fence of the initial dumping ground, and the track points of the muck truck running in the subsequent period of time are outside the electronic fence of the initial dumping ground, it means that the muck truck has left the electronic fence of the initial dumping ground, and the time (i.e., the time of exit), longitude, latitude, and elevation information of the track points of the muck truck moving from the inside of the electronic fence of the initial dumping ground to the outside are recorded. All track points located in the electronic fence of the initial dumping ground are counted to generate a driving record of entering and exiting the electronic fence of the initial dumping ground, and the time, vehicle information (such as vehicle ID or number), etc. of the muck truck entering and exiting the electronic fence of the initial dumping ground are recorded respectively.

[0031] As another example, the initial dumping ground electronic fence is constructed on the electronic map of the geographic information system, and the positions and elevation information of each layer of the initial dumping ground electronic fence are marked on the electronic map of the geographic information system. Then, the initial dumping ground electronic fence is calibrated using a polygon tool on the electronic map of the geographic information system, wherein the calibrated information includes the position, ID, inflection point, longitude, latitude and elevation information of the polygon corresponding to the dumping ground; and the altitude information or other information is set on the calibrated initial dumping ground electronic fence. After the muck truck leaves the initial dumping ground electronic fence, the calibrated information, such as the longitude, latitude and elevation information of the vehicle, is read.

[0032] Step 102, determining the trajectory of the vehicle within the initial dump site electronic fence according to the time information and vehicle information, calculating the buffer zone corresponding to the muck truck according to the buffer zone algorithm and the trajectory, and merging the buffer zone with the historical buffer zone to obtain a new buffer zone.

[0033] In the solution provided in the embodiment of the present application, as a possible implementation method, the buffer zone corresponding to the dump truck is calculated according to the buffer zone algorithm and the trajectory, including: calculating the buffer distance according to the wheelbase of the dump truck and the installation position of the vehicle-mounted positioning device, constructing a parallel strip polygon with the trajectory as the central axis and the buffer distance as the radius according to the buffer zone algorithm; driving the parallel strip polygon to simulate the driving process of the dump truck to obtain the buffer zone corresponding to the dump truck.

[0034] In the solution provided in the embodiment of the present application, if the dump truck completes the operation of dumping the debris in the spoil yard and drives out of the initial spoil yard electronic fence, the behavior of dumping the debris may affect the position of the actual retaining wall at the edge of the spoil yard. Therefore, each time the dump truck completes the operation of dumping the debris and drives out of the spoil yard, the initial spoil yard electronic fence needs to be adjusted dynamically in real time.

[0035] For example, see Figure 4 After the muck truck drives out of the initial dumping ground electronic fence each time, a running track of the muck truck in the initial dumping ground electronic fence is formed according to the track points of the muck truck in the initial dumping ground electronic fence; and the wheelbase of the muck truck and the installation position of the vehicle-mounted locator are determined; then, the buffer distance is calculated according to the running track, the wheelbase and the installation position of the locator, for example, the length of the buffer zone edge from the centerline axis; then, according to the buffer zone algorithm, the running track of the muck truck in the initial dumping ground electronic fence is used as the central axis, and a parallel strip polygon whose distance from the central axis is the buffer distance is determined, and the parallel strip polygon is driven to move to simulate the driving process of the muck truck in the initial dumping ground electronic fence, so as to construct the buffer zone corresponding to the muck truck.

[0036] As another example, let the running track of the muck truck in the initial dump site electronic fence be S, and construct the buffer zone with the running track S as the central axis. In the process of constructing the buffer zone, firstly set a plurality of different points on the running track S, and calculate the coordinates of each point. For example, let one end point of the running track S be A, and its coordinates are (x a ,y a ), the point B adjacent to endpoint A has coordinates (x b ,y b ), if the distance between point B and point A is a preset distance, the preset distance can be configured. Let the positive angle between the line segment formed by point A and point B and the x-axis be α, let Δx = x b -x a , Δy=y b -y a ;When Δx>0, α=arctg(Δy / Δx); When Δx<0, α=arctg(Δy / Δx)+π; When Δx=0, if y b -ya >0, α=π / 2; if y b -y a ≤0, α=3π / 2. The coordinates of the i-th point on the running track S are (x i， y i ), where x i =x a +r*cs(α+i*ε), where r represents the buffer distance and ε represents the spacing or step size between any two points.

[0037] Then, according to r, parallel curves on the left and right sides of the central axis S are generated. For example, a perpendicular line is taken in the advancing direction of the central axis S to obtain the offset point, and the hyperbolic inverse sine between the two points on the central axis S is solved by using the library method of the data module; wherein,

[0038] Assume that the representation format of the points on the central axis is line format, where the line format means that the coordinates of each point are represented in the form of [[lng, lat], [lng, lat]], and the hyperbolic inverse sine between two points on the central axis S is solved by the following formula:

[0039] θ=math.asinh((line[i+1][0]-line[i][0]) / (line[i+1][1]-line[i][1]))

[0040] Here, θ represents the angle between the two points.

[0041] For example, if two offset points a and b are obtained in the vertical direction, and a perpendicular line is taken in the forward direction of the central axis S, the offset point a obtained is (line[i][0]-r*math.cos(d), line[i][0]+r*math.sin(d)), and the offset point b obtained is (line[i][0]+r*math.cos(d), line[i][0]-f*math.sin(d)).

[0042] Next, process the corner radian and determine the buffer zone corresponding to each point. Specifically, assume that the corner is the buffer zone of the point, and the point is divided into convex points and concave points, where the buffer zone corresponding to the convex point is the convex point buffer zone, and the buffer zone corresponding to the concave point is the concave point buffer zone. As an example, according to the calculation method of the point buffer, the arc corresponding to the radius of the buffer zone is solved, and then the buffer zone corresponding to the convex point is obtained by fitting. Further, after determining the buffer zone corresponding to each point, the boundaries of the buffer zones corresponding to each point are connected to obtain the buffer zone.

[0043] Furthermore, in the solution provided in the embodiment of the present application, after calculating the buffer zone corresponding to the dump truck driving out of the dump, the historical buffer zones of the buffer zone are merged to obtain a new buffer zone.

[0044] For example, the buffer zone is a closed curve, and the additional information includes the initial dumping ground electronic fence ID, elevation information, buffer polygons, etc.; the historical buffer zone is an irregularly shaped multiple nested polygon, and the additional information includes the initial dumping ground electronic fence ID, elevation information, buffer polygons, etc.; the joint analysis algorithm is used to merge the buffer zone with the historical buffer zone, and the reorganization boundary of the joint buffer zone is calculated to re-update the historical buffer zone, and the output data content includes the initial dumping ground electronic fence ID, elevation information, generation time, update time, and multiple nested polygons. In the solution provided in the embodiment of the present application, the joint analysis algorithm is used to merge the historical buffer zones of the buffer zone to obtain a new buffer zone, thereby realizing dynamic reorganization and expansion of the buffer zone. Figure 5 A schematic diagram of buffer zone merging provided in an embodiment of the present application.

[0045] Step 103: dynamically adjust the initial spoil dump electronic fence according to the new buffer zone to obtain an adjusted electronic fence.

[0046] In the solution provided in the embodiment of the present application, after the calculated buffer zone is merged with the historical buffer zone to obtain a new buffer zone, it is also necessary to dynamically adjust the initial dump site electronic fence according to the new buffer zone to obtain an adjusted electronic fence. As a possible implementation method, dynamically adjusting the initial dump site electronic fence according to the new buffer zone to obtain an adjusted electronic fence includes: identifying and extracting the outer convex polygon of the new buffer zone, and obtaining the adjusted electronic fence according to the polygon.

[0047] As an example, spatial data processing algorithms are used to analyze the irregular shapes formed after fusion, and the outer convex polygons are identified and extracted. This polygon formed by convex hull simplification is the adjusted electronic fence. Specifically, the new buffer obtained by buffer merging mostly presents multiple nested polygons of irregular shapes. The outermost convex polygon of the new buffer is identified, and the output is called the "dynamic electronic fence" in the spoil dump. The composition data is mostly a simplified closed area polygon composed of multiple trajectory points. In special cases, multiple, independent, non-nested single-ring polygons appear. The system continuously re-identifies through the timer method, and re-sends the changed "dynamic electronic fence" information to the terminal and system platform. The output data content includes the static electronic fence ID, elevation information, generation time, update time, and convex polygon of the spoil dump.

[0048] In the solution provided by the embodiment of the present application, each time the muck truck leaves the electronic fence of the dump, the buffer zone corresponding to the movement of the muck truck in the electronic fence of the dump is calculated according to the buffer zone algorithm, and the electronic fence of the dump is dynamically adjusted according to the buffer zone. By combining the buffer zone with the adjustment of the electronic fence of the dump, not only can the position of the electronic fence be gradually and dynamically advanced according to the landfill progress, which is convenient for night workers to carry out slag dumping operations, but also can ensure the safety of workers and vehicles; it also provides a new extension scheme for the retaining wall in the dump pile process of the simulated open-pit mine area.

[0049] Furthermore, in order to warn vehicles entering the electronic fence of the spoil dump, in one possible implementation, the solution provided in the embodiment of the present application further includes:

[0050] The adjusted electronic fence is sent to the vehicle terminal, and the spatial distance between the actual position of the muck truck and the electronic fence is calculated in real time according to the distance calculation formula;

[0051] An alarm message is generated according to the spatial distance, and the alarm message is fed back so that the driver and the management can perform corresponding operations according to the alarm message.

[0052] As an example, in the solution provided in the embodiment of the present application, the electronic fence of the spoil dump is displayed in real time on the electronic map in a pseudo-three-dimensional form, and the real-time information of the muck truck is displayed; according to the distance calculation formula between two points, the distance between the muck truck and the polygon corresponding to the electronic fence of the spoil dump is calculated in real time. The distance is compared with the preset safety distance; if the distance is greater than the preset safety distance, no alarm information is sent to the vehicle terminal and / or platform; if the distance is less than or equal to the preset safety distance, an alarm information is sent to the vehicle terminal and / or platform, so that the driver or platform manager can promptly understand the safety of the vehicle and personnel in the spoil dump to achieve the purpose of warning.

[0053] Furthermore, in the solution provided in the embodiment of the present application, the position of the dump truck entering and exiting the spoil dump will change as the steps of the spoil dump continue to rise. In order to reduce noise interference, a virtual rectangular entrance is manually set at the vehicle entrance and exit, the alarm points at the entrance are filtered out, and then the updated dynamic electronic fence is sent to the terminal.

[0054] In the solution provided in the embodiment of the present application, as a possible implementation method, it also includes:

[0055] A vehicle entrance and exit is set in the adjusted electronic fence, and the alarm points of the vehicle entrance and exit are filtered out to obtain an updated electronic fence; and the updated electronic fence is sent to the vehicle terminal.

[0056] As an example, a polygon tool is used on an electronic map to mark the location of the spoil dump entrance and convert it into an entrance geographic fence. The collected information includes the static electronic fence ID, turning point longitude, and turning point latitude of the spoil dump. The convex polygon in the electronic fence of the spoil dump is obtained, and the track points within the "entrance geographic fence" are filtered out. The dynamic electronic fence is updated again and sent to the terminal again.
