Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The embodiment of the invention provides a vehicle lap number monitoring method, and particularly relates to a method for planning and counting workload and running lap numbers in advance when a vehicle is used for batch operation according to planning. The inventor finds that the situation of the vehicle in the running process can be monitored through an interconnection technical means, whether the vehicle finishes the whole operation is judged in a mode of judging whether the vehicle starts from a preset starting point, then leaves from the starting point, runs on a preset line and finally reaches a terminal point, and the position situation of the vehicle is discriminated in a mode of setting a starting point electronic fence area, a preset line electronic fence area and a terminal point electronic fence area on the preset line of the vehicle, so that the aim is achieved. Specifically, when a vehicle runs, electronic fences, such as a start point electronic fence, a preset route electronic fence, and an end point electronic fence, are planned in advance, where the electronic fences are GPS points, and a preset running route is taken as an example, and the running route of the vehicle is usually based on an existing route on existing map software. In some construction sites, for example, highway construction sites and high-speed rail construction sites, the driving route of the vehicle on the construction sites does not exist on the existing map software, so that the inventor plans the driving route of the vehicle by taking the GPS point as a unit, specifically, the driving route of the vehicle can be planned on the existing route on the existing map software or an undeveloped area. For electronic fences, including start-point fences, end-point fences, and travel-route fences, existing mapping software can use existing routes or areas on the map to assist in signaling the rough location of the fence. Based on the inventor, a method for monitoring the number of vehicle trips is provided, and particularly, referring to fig. 1, the method for monitoring the number of vehicle trips can comprise the following steps:
and S11, acquiring the electronic fence information of the line. In this embodiment, the fence information may be preset along a preset route based on a map and a preset operation track, and the electronic fence may be composed of a plurality of preset Global Positioning System (GPS) points.
And S12, acquiring the actual running position point of the vehicle. In this embodiment, the position of the vehicle to be monitored can be monitored in real time through the GPS, and the actual operation position point information is uploaded.
S13, calculating operation position point state information based on the operation position point and the electronic fence information, wherein the operation position point state information comprises: a starting point state at a line starting point region, an end point state at a line end point region, or a peripheral state at a region outside the line starting point region and the line end point region.
Specifically, after the electronic fence information is acquired, starting point region electronic fence information and ending point region electronic fence information preset on the electronic fence or a preset peripheral region outside the preset starting point region and the preset ending point region are acquired, a preset comparison point corresponding to the actual running position point of the vehicle on the electronic fence is found based on the acquired information of the actual running position point of the vehicle, the position of the preset comparison point is judged to be in which region of the preset line starting point region, the line ending point region or the preset peripheral region on the electronic fence, and a state result is output.
And S14, determining the number of vehicle passes according to the change of the state information along the time axis.
Specifically, the acquired states are sequentially arranged according to the sequence of the time axis according to the output result obtained in the above steps, and the judgment is performed according to the time sequence, if the arrangement sequence on the time axis is firstly the starting state, then the peripheral state, and finally the ending state, the judgment that the monitored vehicle completes one operation process is performed. According to this principle, the actual number of runs of the vehicle is determined by the change in the time axis.
The starting/ending fence is usually a closed fence, such as a circular fence or a polygonal fence, and when the starting point state and the ending point state are calculated, whether the operation position point is inside the closed fence can be calculated, and after the electronic fence information and the operation position point information are acquired, whether the operation position point is inside the electronic fence can be judged. Specifically, for a circular fence, it may be calculated whether a distance from the operation position point to the center of the circle is smaller than a radius of the circle, and if smaller, the distance is inside the fence, and if larger, the distance is outside the fence. For the polygonal fence, the ray method can be adopted to calculate the times of ray passing through the multi-deformation edge, if the passing times are odd numbers, the operation position point is inside the polygonal fence, and if the passing times are even numbers, the operation position point is outside the polygonal fence. Those skilled in the art should understand that, for a concave polygon, the ray passing through the polygon vertex is a special case and will not be described in detail in this embodiment.
As an exemplary embodiment, it may be possible to calculate only a start point state located in the start point region of the route and an end point state located in the end point region of the route, and detect whether a position change of the actual operation position point is a start point before end point or an end point before start point along the time axis. In order to further ensure the monitoring of the transport vehicle, the information of the running point state can be used for monitoring whether the vehicle runs according to a normal line, namely, the vehicle starts from a starting point and reaches an end point through a preset line, and in order to prevent the transport vehicle from stealing, transporting and transporting in the transportation process, the peripheral state of the transport vehicle outside the starting point area and the end point area can be monitored.
When monitoring the peripheral state, whether the actual operation position point advances according to the preset line or not may be determined, and therefore, a distance between the actual operation position point and the preset line needs to be determined, as an exemplary embodiment, the electronic fence includes a plurality of preset position points arranged according to a preset sequence; calculating the operating position point state information based on the operating position point and the electronic fence information comprises: calculating a plurality of distance information from the operation position point to the electronic fence by utilizing a dichotomy; comparing the plurality of distance information to obtain a preset position point corresponding to the operation position point on the electronic fence; and confirming the state information of the operation position point based on the position of the preset position point.
Specifically, the electronic fence comprises a plurality of preset position points which are arranged in sequence, the preset position points on the electronic fence corresponding to the operation position points are determined by adopting a dichotomy, a plurality of distance information from the operation position to the electronic fence is calculated by utilizing the dichotomy, the information with the nearest distance is determined to be effective information by comparing each distance information, the preset position points corresponding to the operation position points on the electronic fence are obtained at one time, and the distance between the actual operation position points and the preset line can be obtained.
As an exemplary embodiment, the area (the starting point electronic fence area, the ending point electronic fence area or the transportation line electronic fence area) on the electronic fence where the preset position point corresponding to the operation position point on the electronic fence obtained by calculation in the above embodiments is located may be further used to determine which of the starting point state, the peripheral state and the ending point state the state information of the operation position point is. In this embodiment, the concept of bisection may be adopted in calculating the distance from the operating position point to the route, and the route is continuously bisected, so that the two end points of the interval gradually approach the actual operating position point, that is, the distance from the point to the starting point and the distance from the point to the middle point of the route are calculated respectively, and the two points with small distances are selected as the route, and the above calculation is repeated again until the route has only two points, and the iteration is stopped. However, in the practical application process, since many positions of the vehicle running route are curved, and the curvature of some routes is large, the simple bisection method is only adopted to cause misjudgment on the route under the condition of large curvature or spiral path, the traveled route and the non-traveled route cannot be distinguished, so that the distinguishing error is caused, and the abnormal data is obtained. Illustratively, referring to the schematic diagram of the route shown in fig. 2, where the starting point, the middle point and the end point of the route are A, B and C, respectively, and the actual operating position point of the vehicle is D, the distances L1 from D to a, L2 from D to B and L3 from D to C are calculated, respectively, it is obvious that L1 is greater than L3, and therefore, only the route between B and C, i.e., between the middle point and the end point, can be kept by the conventional bisection method for the next bisection. In actual conditions, the distance from the actual operation position point to the starting point is closer, so that in the binary process, it is desirable to keep the line from the actual operation position point to the starting point, but in the actual operation process, the correct result is deleted, and the wrong result is kept. Therefore, in this embodiment, when performing the dichotomy calculation, the comparison data and interval data at each stage are retained first, and no comparison selection is performed during the previous k iterations, and the final algorithm obtains k minimum distance values and performs comparison. The position of the actual operation position point can be accurately obtained. As an optional embodiment, the electronic fence is divided into a plurality of sub-lines according to the number of preset position points; and respectively calculating a plurality of pieces of first distance information from the operation position point to the multi-segment sub-line by utilizing a dichotomy. The method is characterized in that a line is cut into k sections, the curvature of the line can be equivalently reduced after the line is divided into the k sections, and the selection of the k size is determined according to the number of points of a line fence. The distances from the actual operation position points to the K sections of lines are respectively calculated, illustratively, binary iteration can be respectively carried out on the K sections of lines by utilizing a binary method until one point or two points which are closest to the actual operation point are found in each section of lines, and then the distances from the actual operation position points to the K sections of lines can be obtained. The number of times of calculation is obtained according to the number of points N of the fence, and the number of times of calculation is k × floor (log2(N/k)) + 1. And respectively comparing the plurality of distance information to obtain one preset position point or two preset position points on the line corresponding to the minimum distance. Based on the calculated deviation, whether the actual operation position point deviates from the line is calculated.
As an exemplary embodiment, determining the number of vehicle laps from the change in the status information along the time axis includes: judging whether the state information changes along the time axis according to a preset change sequence, wherein the preset change sequence comprises the following steps: firstly, the starting point state, then the peripheral state and finally the end point state or firstly the starting point state and then the end point state are set; when so, the number of vehicle trips is recorded.
Specifically, a time axis is established according to the time of the acquired state, the acquired state information is sequentially judged on the time axis, and if the acquired state is the end point state which is the last state from the starting point state to the peripheral state or the end point state from the starting point state, the calculation logic is satisfied, and the number of the single running times of the vehicle is recorded.
As an exemplary embodiment, the determining the number of vehicle laps from the change in the state information along the time axis includes: if two states adjacent to the peripheral state are the same, the two states are merged into the same state.
Specifically, if two states adjacent to the peripheral state are the same, that is, the relationship on the time axis is that the starting state is the starting state, then the peripheral state, and then the starting state, the state information is merged into the starting state. Similarly, the relationship on the time axis is that the end point state, the peripheral state and the end point state are firstly used, the state information is merged into the end point state, and the relationship on the time axis is that the peripheral state, the peripheral state and the peripheral state are firstly used, and the state information is merged into the peripheral state.
As an exemplary embodiment, confirming the state information of the operation position point based on the position of the preset position point includes: calculating the positions of a plurality of preset position points in a preset time period; and integrating a plurality of calculation results to confirm the state information of the operation position point.
Specifically, the state information of the operating position point is determined according to the acquired position based on the preset position point, when the state information is acquired, the same state information is output by the continuous preset points corresponding to the continuous operating position point, and one state information is output after the number of the continuous preset points meets the preset condition of the preset number.
