[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] The method of this invention can be applied to the scenario of identifying abnormal gas stations, and achieves rapid and accurate identification of abnormal gas stations.

[0049] In related technologies, on-site investigations and reports are used to identify and deal with abnormal gas stations, but this method is inefficient. Therefore, how to analyze, identify, and discover abnormal gas stations in the vast sales market has become a problem that urgently needs to be solved by those skilled in the art.

[0050] The method for generating abnormal gas station clues in this invention accurately determines the effective stopping locations of each vehicle before arriving at a regular gas station based on the electronic waybill data of heavy-duty trucks and the location information of regular gas stations in the geographic information system. Then, it matches the effective stopping locations of each vehicle before arriving at each regular gas station with the location information of the target object in the geographic information system to determine the location of the target oil depot. Finally, based on the location of the target oil depot and the electronic waybill data of each heavy-duty truck, the location information of the abnormal gas station where the heavy-duty truck stopped after leaving the oil depot can be quickly and effectively determined, and abnormal gas station clues can be generated based on the location information of the abnormal gas station, thus improving the efficiency and accuracy of abnormal gas station investigation.

[0051] The following is combined Figures 1-4 The technical solution of the present invention will be described in detail with reference to specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0052] Figure 1 This is a flowchart illustrating an embodiment of the method for generating clues about abnormal gas stations provided by this invention. Figure 1 As shown, the method provided in this embodiment includes:

[0053] Step 101: Based on the electronic waybill data of each vehicle of the target type and the location information of each target gas station, determine the effective stopping position of each vehicle before arriving at each target gas station; the effective stopping position is the position where the stopping time exceeds the first threshold.

[0054] Specifically, among the relevant technologies, identifying and handling abnormal gas stations through on-site investigations and reports is relatively inefficient.

[0055] To address the aforementioned issues, this embodiment of the invention first acquires electronic waybill data for each vehicle of the target type. Optionally, the target type of vehicle can be a heavy-duty freight vehicle. Optionally, according to relevant departmental regulations, heavy-duty freight vehicles weighing 12 tons or more must be equipped with GPS positioning systems, and vehicles engaged in the transportation of hazardous chemicals need to collect GPS operation data in real time. Therefore, electronic waybill data for heavy-duty freight vehicles can be acquired from relevant departments. Optionally, the electronic waybill data includes vehicle information, GPS positioning time, and corresponding latitude and longitude coordinates. Optionally, this GPS data is associated with road network data in a geographic information system, thereby determining the geographical location of each vehicle at different times and its trajectory along the road network.

[0056] Optionally, after acquiring the electronic waybill data of each heavy-duty truck, this embodiment of the invention also acquires the location information of each target gas station. Optionally, in a geographic information system, the information of regular gas stations is usually marked in detail to facilitate the provision of refueling services to passing vehicles. Therefore, the location of the gas station can be determined through the gas station information in the geographic information system, that is, the location information of regular gas stations in the geographic information system is used as the location information of the target gas station. Optionally, the location information of the target gas station can also be determined through other methods and platforms, which are not limited in this embodiment of the invention.

[0057] Optionally, after obtaining the electronic waybill data of each heavy-duty truck and the location information of regular gas stations in the geographic information system, it is possible to determine whether each heavy-duty truck is moving or stationary before arriving at each target gas station based on the real-time location changes of the vehicles in the electronic waybill data; if the time a heavy-duty truck stays at a certain location before arriving at the target gas station exceeds a first threshold, then that location is taken as the valid location where the heavy-duty truck stayed before arriving at the gas station.

[0058] For example, a geographic information system labels gas stations A, B, and C. Based on electronic waybill data, if the duration of a heavy-duty truck m's stay at location x before arriving at gas station A exceeds a first threshold T (optionally, the first threshold can be 30 minutes), then location x can be considered a valid stop location for the heavy-duty truck before arriving at gas station A. Alternatively, if the heavy-duty truck m was in motion without stopping before arriving at gas station B, then there is no valid stop location for the heavy-duty truck before arriving at gas station B.

[0059] Step 102: Determine the location of the target oil depot based on the effective stopping locations of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system;

[0060] Specifically, after determining the effective stopping positions of each vehicle before arriving at each target gas station based on the electronic waybill data of each heavy-duty truck and the gas station location information in the geographic information system, in this embodiment of the invention, the location of the target oil depot is determined based on the effective stopping positions of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system.

[0061] It should be noted that in geographic information systems (GIS), information on regular gas stations is usually clearly marked to facilitate refueling services for passing vehicles. However, oil depots do not provide retail refueling services, and due to security and other reasons, they are not easily marked, therefore such data is usually missing in geographic information systems. Optionally, oil depots include wholesale oil depots of large petrochemical enterprises, oil depots of local refineries, and oil depots for imported refined oil products. Therefore, in this embodiment of the invention, the location of the target oil depot is determined based on the effective stopping locations of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system.

[0062] Optionally, after determining the effective stopping locations of each vehicle before arriving at each target gas station, the effective stopping locations can be matched with the location information of the target objects in the geographic information system; optionally, the target objects include, but are not limited to, parking lots and repair shops; optionally, they can also be matched with target objects in other systems, which is not specifically limited in this embodiment of the invention.

[0063] Optionally, after matching the effective stopping locations of each vehicle before arriving at each target gas station with the location information of the target objects in the geographic information system, if the match is successful, it indicates that the heavy-duty truck has entered the target objects such as parking lots and repair shops and made a valid stop; if the match fails, the valid stopping location that failed to match is taken as the location of the oil depot.

[0064] Step 103: Determine the location information of the abnormal gas station based on the location of the target oil depot and the electronic waybill data of each vehicle;

[0065] Specifically, after determining the location of the target oil depot based on the effective stopping locations of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system, in this embodiment of the invention, the location information of the abnormal gas station is determined based on the location of the target oil depot and the electronic waybill data of each vehicle.

[0066] Optionally, in this embodiment of the invention, the effective stopping point of the heavy-duty truck in the vehicle trajectory after the oil depot can be determined by using the location of the target oil depot and the electronic waybill data of each vehicle. Optionally, the effective stopping point in the vehicle trajectory after the oil depot is matched with the information of regular gas stations, parking lots, and repair shops in the geographic information system. If the match is successful, it indicates that the heavy-duty truck has entered the target object such as the parking lot, repair shop, or regular gas station and made a valid stop. If the match fails, it is determined that the heavy-duty truck has entered an abnormal gas station and made a valid stop.

[0067] Step 104: Generate clues about abnormal gas stations based on their location information.

[0068] Specifically, after determining the location information of abnormal gas stations based on the target oil depot location and the electronic waybill data of each vehicle, abnormal gas station clues can be generated based on the location information. Optionally, abnormal gas stations can be efficiently investigated and processed according to their determined locations, improving the efficiency of abnormal gas station investigation.

[0069] The method described in the above embodiments accurately determines the effective stopping locations of each vehicle before arriving at a regular gas station based on the electronic waybill data of heavy-duty trucks and the location information of regular gas stations in the geographic information system. Then, it matches the effective stopping locations of each vehicle before arriving at each regular gas station with the location information of the target object in the geographic information system to determine the location of the target oil depot. Finally, based on the location of the target oil depot and the electronic waybill data of each heavy-duty truck, it can quickly and effectively determine the location information of the abnormal gas station where the heavy-duty truck stopped after leaving the oil depot, and generate abnormal gas station clues based on the location information of the abnormal gas station, thus improving the efficiency and accuracy of abnormal gas station investigation.

[0070] In one embodiment, determining the location of the target oil depot based on the effective stopping locations of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system includes:

[0071] Based on the effective stopping locations of each vehicle before arriving at each target gas station, determine the target stopping location of each vehicle before arriving at each target gas station;

[0072] The location of the target oil depot is determined based on the target stopping location of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system.

[0073] Specifically, to improve the efficiency and accuracy of identifying oil depot locations and abnormal gas stations, this embodiment of the invention determines the target stopping location of each vehicle before it reaches each target gas station based on the effective stopping locations of each vehicle before reaching each target gas station. Optionally, hotspot effective stopping locations are used as target stopping locations, that is, effective stopping locations where multiple vehicles stop are used as target stopping locations, while effective stopping locations where only a few vehicles stop and with a low number of stops are discarded. Then, by matching the effective stopping locations where multiple vehicles stop with the location information of the target object in the geographic information system, the location of the target oil depot can be determined, thereby improving the efficiency and accuracy of identifying oil depot locations and abnormal gas stations.

[0074] In the above embodiments, the effective stopping locations of hotspots are used as target stopping locations, that is, the effective stopping locations where multiple vehicles stop are used as target stopping locations. Then, the effective stopping locations where multiple vehicles stop are matched with the location information of the target object in the geographic information system, so as to quickly and accurately determine the location of the oil depot, thereby improving the efficiency and accuracy of the investigation of oil depot locations and abnormal gas stations.

[0075] In one embodiment, determining the target stopping position of each vehicle before it reaches each target gas station, based on the effective stopping positions of each vehicle before it reaches each target gas station, includes:

[0076] Based on the effective stopping locations of each vehicle before arriving at each target gas station, determine the number of stops corresponding to each effective stopping location;

[0077] Based on the number of times a vehicle stops at each valid stop location, the target stop location before each vehicle reaches each target gas station is determined from the valid stop locations.

[0078] Specifically, in order to improve the efficiency and accuracy of identifying oil depot locations and abnormal gas stations, this embodiment of the invention determines the target stopping location of each vehicle before it reaches each target gas station based on the effective stopping location of each vehicle before it reaches each target gas station. That is, the effective stopping location of the hotspot is used as the target stopping location. Then, the effective stopping location of the hotspot is matched with the location information of the target object in the geographic information system to determine the location of the oil depot, thereby achieving the goal of improving the efficiency and accuracy of identifying oil depot locations and abnormal gas stations.

[0079] Optionally, a target stopping location can be determined from the valid stopping locations based on the number of times a vehicle stops at each valid stopping location; that is, valid stopping locations with a higher number of stops are selected as target stopping locations, while valid stopping locations with a lower number of stops are discarded, thereby improving the efficiency and accuracy of investigating the location of oil depots and abnormal gas stations.

[0080] The method described in the above embodiment determines the target stopping location from the valid stopping locations based on the number of times the vehicle stops at each valid stopping location; that is, valid stopping locations with a higher number of stops are used as target stopping locations, while valid stopping locations with a lower number of stops are discarded, thereby improving the efficiency and accuracy of investigating the location of oil depots and abnormal gas stations.

[0081] In one embodiment, determining the target stopping position of each vehicle before reaching each target gas station from the valid stopping positions based on the number of stops corresponding to each valid stopping position includes:

[0082] If the number of times a vehicle stops at a valid stopping location exceeds the second threshold, the valid stopping location will be determined as the target stopping location.

[0083] Specifically, in this invention, the target stopping position is determined from the valid stopping positions based on the number of times the vehicle stops at each valid stopping position; that is, the valid stopping positions with more stopping times are taken as the target stopping positions, while the valid stopping positions with fewer stopping times are discarded, thereby improving the efficiency and accuracy of investigating the location of oil depots and abnormal gas stations.

[0084] Optionally, if the number of times a vehicle stops at a valid stopping location exceeds a second threshold, the valid stopping location is determined as the target stopping location. Optionally, the second threshold can be determined based on actual circumstances, and is not specifically limited in this embodiment of the invention.

[0085] For example, if vehicles a, b, c, and d effectively stop a total of 8 times within a certain period of time at location A, vehicles a, b, c, and e effectively stop a total of 5 times within the same period of time at location B, and vehicle a stops once at location C, then effective stop locations A and B can be used as target stop locations. Furthermore, target oil depots and abnormal gas station locations can be determined based on target stop locations A and B. This significantly improves the efficiency and accuracy of identifying oil depot locations and abnormal gas stations compared to determining target oil depots and abnormal gas station locations based solely on effective stop locations A, B, and C.

[0086] The method described in the above embodiment determines the effective stopping location as the target stopping location when the number of vehicle stops corresponding to the effective stopping location is greater than a second threshold. Further, the location of the oil depot and the location of the abnormal gas station are determined based on the target stopping location, which can effectively improve the efficiency and accuracy of the investigation of oil depot locations and abnormal gas stations.

[0087] In one embodiment, determining the location of the target oil depot based on the target stopping location of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system includes:

[0088] The location information of the target's previous stop location before the target gas station is matched with the location information of the target object in the geographic information system to obtain the matching result; the target object includes at least one of the following: parking lot, auto repair shop and gas station;

[0089] The location of the target oil depot is the location where the matching result fails.

[0090] Specifically, in geographic information systems (GIS), information on regular gas stations is typically marked in detail to facilitate refueling services for passing vehicles. However, oil depots do not provide retail refueling services, and due to security and other reasons, they are not easily marked, thus such data is usually missing in geographic information systems. Optionally, oil depots include wholesale oil depots of large petrochemical enterprises, oil depots of local refineries, and oil depots for imported refined oil products. Therefore, in this embodiment of the invention, the location of the oil depot is determined based on the target stopping location of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system.

[0091] Optionally, after determining the target stopping location of each vehicle before arriving at each target gas station, the target stopping location can be matched with the location information of the target object in the geographic information system to obtain the matching result; optionally, the target object includes, but is not limited to, parking lots, auto repair shops and regular gas stations; optionally, it can also be matched with target objects in other systems, which is not limited in this embodiment of the invention.

[0092] Optionally, after matching the target stopping location of each vehicle before arriving at each target gas station with the location information of the target object in the geographic information system, if the match is successful, it indicates that the heavy-duty truck has entered the target object such as the parking lot, auto repair shop and regular gas station and made a valid stop; if the match fails, the target stopping location that failed to match is taken as the location of the oil depot.

[0093] The method described in the above embodiment, after determining the target stopping location of each vehicle before arriving at each target gas station, matches the target stopping location with the location information of the target object in the geographic information system to obtain a matching result. If the match is successful, it indicates that the heavy-duty truck has entered the target object such as a parking lot, auto repair shop, or regular gas station and made an effective stop. If the match fails, the target stopping location that failed to match is taken as the location of the oil depot, thereby quickly and effectively determining the location of the oil depot. Based on the location of the oil depot and the geographic information system, the location of abnormal gas stations can also be quickly and accurately determined, improving the efficiency and accuracy of investigating the location of oil depots and abnormal gas stations.

[0094] In one embodiment, the location information of the abnormal gas station is determined based on the location of the target oil depot and the electronic waybill data of each vehicle, including:

[0095] Based on the location of the target oil depot and the electronic waybill data of each vehicle, determine the effective stopping points of each vehicle on the driving route after the location of the target oil depot;

[0096] The location information of the abnormal gas station is determined based on the effective stopping positions of each vehicle on its driving path after the target oil depot location and the location information of the target object in the geographic information system.

[0097] Specifically, after determining the location of the target oil depot based on the effective stopping locations of each vehicle before arriving at each target gas station and the location information of the target object in the geographic information system, in this embodiment of the invention, the location information of the abnormal gas station is determined based on the location of the target oil depot and the electronic waybill data of each vehicle.

[0098] Optionally, in this embodiment of the invention, the effective stopping points of heavy-duty trucks in the vehicle trajectory after the oil depot can be determined by using the location of the target oil depot and the electronic waybill data of each vehicle. Optionally, the effective stopping points in the vehicle trajectory after the oil depot are matched with the location information of target objects in the geographic information system. Optionally, the target objects in the geographic information system include, but are not limited to, regular gas stations, parking lots, and repair shops. That is, the effective stopping points in the vehicle trajectory after the oil depot are matched with the location information of regular gas stations, parking lots, and repair shops in the geographic information system. If the match is successful, it indicates that the heavy-duty truck has entered the target objects such as parking lots, repair shops, and regular gas stations and made an effective stop. If the match fails, it is determined that the heavy-duty truck has entered an abnormal gas station and made an effective stop, thereby accurately determining the location information of the abnormal gas station. Then, based on the location information of the abnormal gas station, abnormal gas station clues can be generated, improving the efficiency of abnormal gas station investigation.

[0099] The method described in the above embodiments can determine the effective stopping points of heavy-duty trucks in their vehicle trajectories after the oil depot by using the location of the target oil depot and the electronic waybill data of each vehicle. Optionally, the effective stopping points in the vehicle trajectories after the oil depot are matched with the location information of the target object in the geographic information system. If the match is successful, it indicates that the heavy-duty truck has entered the target object such as a parking lot, repair shop, or regular gas station and made an effective stop. If the match fails, it is determined that the heavy-duty truck has entered an abnormal gas station and made an effective stop, thereby accurately determining the location information of the abnormal gas station. Furthermore, based on the location information of the abnormal gas station, clues about abnormal gas stations can be generated, improving the efficiency of investigating abnormal gas stations.

[0100] In one embodiment, the location information of the abnormal gas station is determined based on the effective stopping positions of each vehicle on its driving path after the target oil depot location and the location information of the target object in the geographic information system, including:

[0101] The location information of the effective stopping locations along the driving path after the target oil depot location is matched with the location information of the target object in the geographic information system to obtain the matching results;

[0102] Valid locations where a match fails are identified as the locations of abnormal gas stations.

[0103] Specifically, in this embodiment of the invention, the location information of valid stops along the driving path after the target oil depot is matched with the location information of the target object in the geographic information system to obtain a matching result. Valid stops where the matching result fails are taken as the location of the abnormal gas station. Optionally, the target objects in the geographic information system include, but are not limited to, legitimate gas stations, parking lots, and repair shops. That is, valid stops along the vehicle trajectory after the oil depot are matched with the location information of legitimate gas stations, parking lots, and repair shops in the geographic information system. If the match is successful, it indicates that the heavy-duty vehicle has entered the parking lot, repair shop, or legitimate gas station and made a valid stop. If the match fails, it is determined that the heavy-duty vehicle has entered an abnormal gas station and made a valid stop, thus accurately determining the location information of the abnormal gas station. Based on the location information of the abnormal gas station, clues about abnormal gas stations can be generated, improving the efficiency of investigating abnormal gas stations.

[0104] The method described above matches the effective stopping points in the vehicle trajectory after the oil depot with the location information of the target object in the geographic information system. If the match is successful, it indicates that the heavy-duty truck has entered the target object such as a parking lot, repair shop, or regular gas station and made an effective stop. If the match fails, it is determined that the heavy-duty truck has entered an abnormal gas station and made an effective stop, thus accurately determining the location information of the abnormal gas station. Furthermore, based on the location information of the abnormal gas station, clues about abnormal gas stations can be generated, improving the efficiency of investigating abnormal gas stations.

[0105] In one embodiment, before determining the effective stopping position of each vehicle before arriving at each target gas station based on the electronic waybill data of each vehicle of the target type and the location information of each target gas station, the method further includes:

[0106] Obtain electronic waybill data for multiple vehicles of the target type;

[0107] Based on the electronic waybill data of each vehicle, determine the effective stopping location of each vehicle;

[0108] Based on the effective stopping locations of each vehicle, determine the target stopping locations within the target area;

[0109] Based on the target location and the location information of gas stations in the target area, identify at least one target gas station.

[0110] Specifically, in this embodiment of the invention, by acquiring electronic waybill data of multiple vehicles of the target type, optionally, electronic waybill data of heavy-duty freight vehicles can be acquired; optionally, according to the regulations of relevant departments, heavy-duty freight vehicles weighing 12 tons or more must be equipped with GPS positioning systems, and vehicles engaged in the transportation of hazardous chemicals need to collect GPS operation data in real time, so electronic waybill data of heavy-duty freight vehicles can be acquired from relevant departments; optionally, the electronic waybill data includes vehicle information, GPS positioning time, and corresponding latitude and longitude coordinates; optionally, this GPS data is associated with road network data in a geographic information system, so that the geographical location of each vehicle at different times and the trajectory along the road network can be accurately determined.

[0111] Optionally, after obtaining the electronic waybill data for heavy-duty freight vehicles, the effective stopping location of each vehicle can be determined based on the electronic waybill data. Optionally, the real-time location changes of each heavy-duty freight vehicle in the electronic waybill data can be used to determine whether each heavy-duty freight vehicle is moving or stationary. Optionally, if the duration of a heavy-duty freight vehicle's stay at a certain location exceeds a first threshold, then that location is considered the effective stopping location of the heavy-duty freight vehicle. Optionally, the first threshold can be determined based on actual conditions, and is not limited in this embodiment of the invention.

[0112] Optionally, after determining the effective stopping locations of each heavy-duty truck, a target stopping location in the target area can be determined based on the effective stopping locations of each heavy-duty truck; optionally, hotspot effective stopping locations can be used as target stopping locations; optionally, target stopping locations can be determined from the effective stopping locations based on the number of times vehicles stop at each effective stopping location; that is, effective stopping locations with more stops are used as target stopping locations, and effective stopping locations with fewer stops are discarded; optionally, if the number of times vehicles stop at an effective stopping location is greater than a threshold, that effective stopping location is determined as the target stopping location. Optionally, the threshold can be determined according to actual conditions, and is not specifically limited in this embodiment of the invention.

[0113] Optionally, after determining the target location in the target area, at least one target gas station can be identified based on the target location and the gas station location information in the target area. Optionally, the target location can be matched with the location information of regular gas stations in the geographic information system to determine the location of the target gas station. Then, the location of the oil depot can be determined based on the target gas station, and the abnormal gas station can be identified based on the oil depot, which can effectively improve the efficiency and accuracy of the investigation of oil depot location and abnormal gas station.

[0114] The method described in the above embodiment, after acquiring the electronic waybill data of heavy-duty freight vehicles, can determine the effective stopping locations of each vehicle based on the electronic waybill data; then, based on the number of times the vehicle stops at each effective stopping location, the target stopping location is determined from the effective stopping locations; finally, the target stopping location is matched with the location information of regular gas stations in the geographic information system to determine the location of the target gas station; further, the location of the target oil depot is determined based on the target gas station, and abnormal gas stations are identified based on the target oil depot, which can effectively improve the efficiency and accuracy of investigating oil depot locations and abnormal gas stations.

[0115] For example, such as Figure 2 The flowchart illustrating the method for generating clues about abnormal gas stations illustrates that, since refined oil logistics transportation typically uses heavy-duty trucks, this embodiment of the invention analyzes and judges vehicle GPS trajectories, identifies trajectory hotspots, matches them with geographic information data, and accurately locates abnormal gas station locations based on the matching results. The specific process is as follows:

[0116] First, obtain the electronic waybill data of heavy-duty trucks for the period of interest, including vehicle information, GPS location time and corresponding latitude and longitude coordinates. This GPS data reflects the trajectory of each vehicle's geographical location at different times.

[0117] Then, the inflow and outflow hotspots of a large number of heavy-duty truck trajectories are statistically analyzed. The process is as follows: The real-time location changes of the vehicles are used to determine whether they are moving or stationary. If stationary, a stationary time threshold T is set. When the stationary time exceeds T, the time and location are marked as a valid stationary position. Preferably, T is set to 30 minutes. The valid stationary positions on the trajectories are statistically analyzed; optionally, stationary positions concentrated within a certain distance are statistically analyzed as the same location. Preferably, this distance is set to 100 meters.

[0118] The stopping locations are sorted by the frequency of effective stops, and the top-ranked locations are identified as hotspots. Since vehicles often stop in an area rather than a single geometric point during loading and unloading, analyzing a large number of finite stopping coordinates reveals that stopping locations are clustered within a certain area. Therefore, hotspots are not geometric points, but rather concentrated areas. To accurately reflect this characteristic, we use the following algorithm to extract these hotspots. First, the map area of ​​interest is divided into a square grid with sides of 10 meters. Second, a square with side length *a* is moved from the top left corner of the map from left to right, moving one grid (10 meters) at a time, and the frequency of effective stops by vehicles within the square is counted and recorded. This process continues until the square reaches the rightmost edge of the map, then returns to the leftmost edge and moves down one grid (10 meters), continuing the scan from left to right and counting the frequency. This yields the frequency distribution of effective stops within the map area. The distribution of hotspots is obtained by sorting the frequencies. Preferably, the side length of the square is set to *a* = 100 meters.

[0119] Next, the location of the oil depot is determined from the inflow and outflow hotspots of heavy-duty vehicles. The process is as follows: The hotspots identified above are matched with gas station information in the geographic information system, and the gas station hotspots are marked; the trajectories of all vehicles flowing into the gas stations are searched, the outflow hotspots of the trajectories are determined, and they are matched with parking lot and repair shop information in the geographic information system to eliminate interference; the frequency of outflow hotspots of the inflow trajectories to the gas stations is counted and sorted, and the top-ranked hotspots are identified as the location of the oil depot.

[0120] It should be noted that oil depots include wholesale oil depots of large petrochemical enterprises, oil depots of local refineries, and oil depots for imported refined oil products. Geographic Information Systems (GIS) typically provide detailed information on legitimate gas stations to facilitate refueling services for passing vehicles. However, oil depots do not offer retail refueling services, and due to security and other reasons, they are not easily marked; therefore, such data is usually missing from GIS records. While satellite imagery can be used to identify potential oil depots, this method is neither comprehensive nor guaranteed to be accurate.

[0121] Finally, the location of the illegally operated fuel tanks is determined by tracking the trajectories of the freight vehicles departing from the oil depot, thus identifying the locations of abnormal gas stations. Because illegally operated fuel tanks are often hidden and have low traffic, the number of vehicle trajectories flowing in and out of these locations is relatively small, making them unlikely to become hotspots. In this embodiment of the invention, the next valid stopping point in the vehicle trajectory (which may not be a hotspot) is found and matched with information on legitimate gas stations, parking lots, and repair shops in the geographic information system. If all are excluded, the location is identified as a possible abnormal gas station. Furthermore, the trajectories of all freight vehicles departing from the oil depot are analyzed and processed to identify possible abnormal gas station locations, and the frequency is statistically analyzed and sorted to generate location clues for abnormal gas stations.
