S101, matching the stop point data of the vehicle with the interest point data to obtain a stop data set of the gas station.
In one possible implementation, before performing step S101, acquiring track data and national point of interest data of the vehicle is further included.
For example, GPS trajectory data for a plurality of vehicles may be obtained, wherein the GPS trajectory points are vehicle location data reported in real time by GPS (GlobalPositioning System ) devices deployed on the vehicles. Generally, when the GPS device reports in real time, the reporting time interval may be set according to the actual situation, and the preferred time interval in the present application is 10S. It should be noted that, in addition to the vehicle-mounted GPS device being used to report the track data of the vehicle in real time, the present application may also be used to locate the track of the vehicle and report the track data by the Beidou device.
And then acquiring national point of interest data according to a national POI information database in the network, for example acquiring the national point of interest data through a hundred-degree POI database, and acquiring the national point of interest data through a GoldPOI database.
Further, judging whether the vehicle stops according to the time information and the speed information in the track data, and obtaining the stop point data of the vehicle.
Specifically, calculating a stop point according to a track time axis, for example, when the speed is less than 5 km/h, calculating the distance between each subsequent point and the base point, if the distance is less than or equal to 200 m continuously and the duration is greater than 2 minutes, marking the base point as a stop start point, taking the stop start time of the base point as the stop start time of the time and taking the stop longitude and latitude of the base point as the stop longitude and latitude of the time, continuously judging all subsequent running track points, finding a point, and positioning the point at a distance from the base point and greater than 200 m for a duration exceeding 2 minutes, marking the stop of the time, and taking the time difference between the end point and the base point as the total stop duration of the time. And obtaining the stop point data of the vehicle.
Further, matching the stop point data of the vehicle with the interest point data to obtain a stop data set of the gas station, including: calculating the distance between the target stop point and the interest point of the gas station contained in the area where the target stop point is located; when the distance is smaller than the preset distance threshold and the stop time length is within the first preset stop time length interval, the target stop point is a gas station stop, and the target stop point is added into the gas station stop data set.
In one possible implementation manner, the target stop point is a stop point to be calculated, the distance between the target stop point and the interest point of the gas station in the area where the target stop point is located is calculated, when the distance is smaller than a preset distance threshold value and the stop time length is within a first preset stop time length interval, the target stop point is a gas station stop, and the target stop point is added into the gas station stop data set. Wherein, the distance threshold and the first preset parking time interval can be set by a person skilled in the art according to actual situations. The gas station parking data set comprises license plate numbers, license plate colors, starting parking time, ending parking time, parking duration, POI_ID, POI names, parking distances, parking longitudes and parking latitudes of vehicles parked at the gas station.
In one possible implementation, the method further includes determining whether the target stop point is a gas station stop based on the road network data. For each target stop point to be calculated, if the distance between the target stop point to be calculated and the gas station POI point in the area where the target stop point to be calculated is smaller than a first distance threshold value, determining whether the distance between the gas station POI point and the corresponding gas station road is smaller than a second distance threshold value; and if the target stop point is smaller than the second distance threshold value, determining that the target stop point is a gas station stop. If the distance between the target stop point and the corresponding gas station road is not smaller than the second distance threshold value, and the distance between the target stop point and the corresponding gas station road is larger than the third distance threshold value, determining that the target stop point is a gas station stop. Wherein the first distance threshold is greater than the second distance threshold, and the second distance threshold is greater than the third distance threshold.
By analyzing a large number of historical track data of vehicles, a gas station parking data set of the vehicles can be obtained.
S102, screening abnormal refueling vehicles which are not in the gas station parking data set according to track data of the vehicles in a preset time period.
Through the above steps, the state of refueling of all vehicles in the country has been calculated, and if the vehicle is operating normally but is not refueled, i.e. the stopping points of the vehicle are all not in the filling station stopping data set, the vehicle may be suspected to be refueled at other illegal filling stations.
In one embodiment, abnormal fueling vehicles that are not in the fueling station docking data set are screened based on trajectory data for a predetermined period of time of the vehicle. Specifically, track data of a plurality of vehicles in a last period of time are acquired, the operation mileage of the vehicle is calculated according to the track data in a preset period of time of the vehicle, for example, the latest report point of the vehicle has 10 days, and when the operation mileage of a certain day is greater than the preset operation mileage, the vehicle is determined to normally operate in the certain day.
Calculating a stop point according to the track data of the normally operated vehicle, and when the stop point of the normally operated vehicle is contained in the gas station stop data set, indicating that the vehicle is a normally refueled vehicle. When all stops of a normally operated vehicle are not located in the gas station stop data set, the operating vehicle is an abnormally fueled vehicle.
S103, clustering the stop points of the abnormal refueling vehicle, and taking a clustering area which does not contain the preset interest points as an abnormal area.
Further, the stopping points of the abnormal refueling vehicles are clustered through a k-means clustering algorithm, and a plurality of clustering areas are obtained. In one possible implementation, the k-means clustering algorithm includes the steps of:
1. randomly selecting k points as clustering centers;
2. calculating the distances from each point to k clustering centers respectively, and then dividing the points to the nearest clustering centers, so that k clusters are formed;
3. re-computing the centroid of each cluster;
4. repeating the steps 2-4 until the position of the mass center is not changed any more or the set iteration times are reached.
In another possible implementation manner, other clustering algorithms such as a DBSCAN clustering algorithm may also be used, and the embodiment is not limited specifically.
Searching POI points in a preset range of each clustering area, further classifying the POI types, and if the POI points are not contained in the preset range of the clustering area or are not contained in POI points which are strongly associated with freight transportation, such as ports and docks, railway stations, airport freight transportation, logistics parks, industrial parks, outdoor parking lots, farmer markets, furniture building material markets, gas stations, service areas and the like, the clustering area is an abnormal area.
According to the step, abnormal areas where the vehicle always stops abnormally are obtained through clustering the stop points of the abnormal refueling vehicle and combining with POI data.
S104, judging whether the vehicles in the abnormal area meet the preset refueling conditions, and if so, judging that the abnormal area is an illegal refueling station.
Further, the parking behavior of the vehicle in the abnormal region is analyzed to determine whether the abnormal region is an illegal fueling station.
In an alternative embodiment, firstly, the parking duration and the parking times of the vehicle in the abnormal area are calculated, and when the parking duration of the vehicle is in a second preset parking duration interval and the parking times are in a preset parking times interval, the vehicle is a suspected illegal refueling vehicle. Further, when the number of suspected illegal refueling vehicles in the abnormal area is in the preset number interval, the abnormal area is an illegal refueling station. For example, within a week, the number of vehicles parked abnormally in the area is between [20-100] and the area may be an illegal fueling station.
