Description

Technical Field

[0001] The present invention relates to the field of vehicle monitoring technology, and in particular to a method and system for monitoring hazardous chemical vehicles based on highway big data. Background Art

[0002] Hazardous chemicals are a general term for flammable, explosive, highly corrosive or toxic substances, mainly including explosives, compressed (liquefied) gases, flammable liquids, flammable solids, oxidizers and organic peroxides, poisons, radioactive substances and corrosive substances. As dangerous goods, the state requires special vehicles for transportation. Hazardous chemical transport vehicles mainly refer to special vehicles with an open top cargo box, a front exhaust pipe and a spark-proof device installed to transport hazardous chemicals such as petrochemicals, explosives, and firecrackers. Due to the wide variety of dangerous goods, there are also several types of hazardous chemical transport vehicles. In the light truck industry, the main ones are explosion-proof vehicles (blasting equipment, fireworks and firecrackers), flammable gas van transport vehicles (gas cylinder vehicles) and tanker trucks (mobile refueling vehicles), which are several special vehicles with special announcements.

[0003] With technological advancements and rapid economic development, the demand for hazardous chemicals is growing across various industries, including industrial construction, and the transportation of hazardous chemicals is also increasing. Therefore, the safety of hazardous chemical road transportation cannot be underestimated. Once a hazardous chemical road transportation accident occurs, the harm is severe and the impact is widespread, easily causing casualties and property losses. Currently, the supervision of hazardous chemical vehicles still has potential risks, especially for hazardous chemical vehicles on highways. The monitoring methods are simple and inefficient, and it is impossible to conduct more targeted monitoring. Summary of the Invention

[0037] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0038] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0039] Example 1

[0040] like Figure 1 As shown, a method for monitoring hazardous chemical vehicles based on highway big data includes the following steps:

[0041] S1: Obtain highway big data through ETC gantries, toll collection systems, and monitoring systems installed on highways, and obtain highway driving trajectories of hazardous chemical vehicles based on the highway big data;

[0042] Specifically, multiple monitoring points are set up on the highway to collect highway big data, including but not limited to ETC gantries, toll collection systems and monitoring systems. Highway big data is obtained through the ETC gantries, toll collection systems and monitoring systems installed on the highway. Highway big data includes but is not limited to the type of vehicles entering the highway, entry time, exit time, and checkpoint locations passed by, etc. The highway driving trajectory of hazardous chemical vehicles is obtained based on the highway big data.

[0043] S2: Obtain GPS data of the hazardous chemicals vehicle and determine the GPS status based on the GPS data;

[0044] Specifically, to ensure the supervision of hazardous chemical vehicles transporting hazardous chemicals, most hazardous chemical vehicles are equipped with GPS devices. After capturing a hazardous chemical vehicle on a highway, the GPS data of the hazardous chemical vehicle is obtained through the GPS device installed on the hazardous chemical vehicle. Based on the GPS data, it is determined whether the GPS device of the hazardous chemical vehicle is in working condition. For example, the GPS data can detect the position movement of the hazardous chemical vehicle, the movement distance, the time node of the position change, and other data that can indicate that the GPS device is operating. When this data is constantly changing and the change frequency is consistent, it indicates that the GPS device of the hazardous chemical vehicle is in the on state, and the GPS status judgment result is normal. When this data suddenly changes to 0 or stops changing, it indicates that the GPS device of the hazardous chemical vehicle is in the off state, and the GPS status judgment result is abnormal.

[0045] S3: Marking the vehicle based on the GPS status judgment result and the highway driving trajectory of the hazardous chemical vehicle, and reporting the marked vehicle information;

[0046] Specifically, when the GPS status judgment result is abnormal, it indicates that the hazardous chemical vehicle has turned off the GPS device and has violated the regulations. The hazardous chemical vehicle will be marked as a GPS abnormal vehicle and an information report will be made.

[0047] When the GPS of a hazardous chemical vehicle is abnormal, the driving trajectory of the hazardous chemical vehicle cannot be obtained based on the GPS data. Therefore, after completing one information report, it is necessary to obtain the traces of the hazardous chemical vehicle passing through the ETC gantry, toll collection system and monitoring system installed on the highway, and compare them with the prescribed route. That is, the highway driving trajectory of the hazardous chemical vehicle obtained based on the highway big data is matched with the prescribed route to determine whether the highway driving trajectory of the hazardous chemical vehicle is consistent with the prescribed route. If not, it means that the hazardous chemical vehicle did not travel according to the prescribed route, and the hazardous chemical vehicle is marked as a vehicle with abnormal trajectory, and a second information report is made.

[0048] Furthermore, when the GPS status judgment result is normal, indicating that the GPS device of the hazardous chemical vehicle is currently in the on-state, the GPS driving trajectory of the hazardous chemical vehicle is extracted based on the GPS data obtained by the GPS device of the hazardous chemical vehicle. The GPS driving trajectory of the hazardous chemical vehicle is matched with the highway driving trajectory of the hazardous chemical vehicle to determine whether the GPS driving trajectory of the hazardous chemical vehicle is consistent with the highway driving trajectory captured by the ETC gantries, toll collection systems, and monitoring systems installed on the highway. If inconsistent, it indicates that the actual installation location of the GPS device of the hazardous chemical vehicle may be suspicious.

[0049] For example, if hazardous chemical vehicle A maliciously removes its GPS device and installs it on vehicle B, while vehicle B follows the designated hazardous chemical transport route, vehicle A, which is actually carrying hazardous chemicals, does not follow the designated route. The GPS trajectory of hazardous chemical vehicle A is inconsistent with its actual trajectory. In this case, based solely on its GPS trajectory, it is impossible to determine that hazardous chemical vehicle A has violated regulations. Therefore, by matching the GPS trajectory of hazardous chemical vehicles with their highway trajectories, we can prevent hazardous chemical vehicles from evading regulations and other violations.

[0050] When it is determined that the GPS driving trajectory of a hazardous chemical vehicle is inconsistent with the highway driving trajectory, the hazardous chemical vehicle is marked as a vehicle with abnormal trajectory, and the information of the vehicle with abnormal trajectory is reported.

[0051] Relevant departments may impose different degrees of punishment on hazardous chemical vehicles that violate regulations based on the number of times information is reported. For example, when a hazardous chemical vehicle is only reported once, the relevant departments may issue a warning or a minor penalty. When a hazardous chemical vehicle is reported twice, it indicates that the GPS of the hazardous chemical vehicle is abnormal and it has not been driven according to the prescribed route, which means there are two violations. The relevant departments may impose heavier penalties on hazardous chemical vehicles that violate regulations multiple times based on the number of times information is reported.

[0052] After the vehicle is labeled, the corresponding hazardous chemical vehicle driving information is obtained. In practice, this vehicle driving information can be obtained through various channels, such as the electronic waybill system archived by transportation departments or from waybill information backed up by transportation companies. Vehicle driving information includes but is not limited to the license plate, vehicle company, driver profile, escort profile, and hazardous chemical information, as well as the driving trajectory obtained above.

[0053] After obtaining the driving information of the marked vehicle, it will be reported to the relevant departments in an automatic push manner, so that the relevant departments can formulate corresponding plans, take corrective measures quickly, conduct on-site inspections of the hazardous chemical vehicles that have violated the regulations, and reduce safety hazards.

[0054] Example 2

[0055] like Figure 2 As shown, a hazardous chemical vehicle monitoring system based on highway big data includes:

[0056] Highway driving trajectory acquisition module: used to obtain highway big data through the ETC gantries, toll collection systems and monitoring systems installed on the highway, and obtain the highway driving trajectory of hazardous chemical vehicles based on the highway big data;

[0057] GPS status judgment module: used to obtain GPS data of the hazardous chemicals vehicle and perform GPS status judgment based on the GPS data;

[0058] The marking and reporting module is used to mark vehicles and report information of the marked vehicles based on the GPS status judgment results and the highway driving trajectory of hazardous chemicals vehicles.

[0059] Specifically, multiple monitoring points are set up on the highway to collect highway big data, including but not limited to ETC gantries, toll collection systems and monitoring systems. The highway driving trajectory acquisition module obtains highway big data through the ETC gantries, toll collection systems and monitoring systems installed on the highway. The highway big data includes but is not limited to the type of vehicles entering the highway, the entry time, the exit time, and the checkpoint locations passed by, etc. The highway driving trajectory of hazardous chemical vehicles is obtained based on the highway big data.

[0060] Furthermore, to ensure the supervision of hazardous chemical vehicles transporting hazardous chemicals, most hazardous chemical vehicles are equipped with GPS devices. After capturing a hazardous chemical vehicle on a highway, the GPS data of the hazardous chemical vehicle is obtained through the GPS device installed on the hazardous chemical vehicle. The GPS status judgment module determines whether the GPS device of the hazardous chemical vehicle is in working condition based on the GPS data. For example, the GPS data can detect the position movement of the hazardous chemical vehicle, the movement distance, the time node of the position change, and other data that can indicate that the GPS device is operating. When this data is constantly changing and the change frequency is consistent, it indicates that the GPS device of the hazardous chemical vehicle is in the on state, and the GPS status judgment result is normal. When this data suddenly changes to 0 or stops changing, it indicates that the GPS device of the hazardous chemical vehicle is in the off state, and the GPS status judgment result is abnormal.

[0061] When the GPS status judgment result is abnormal, it indicates that the hazardous chemical vehicle has turned off the GPS device and has violated the regulations. The marking and reporting module will mark the hazardous chemical vehicle as a GPS abnormal vehicle and report the information.

[0062] When the GPS of a hazardous chemical vehicle is abnormal, the driving trajectory of the hazardous chemical vehicle cannot be obtained based on the GPS data. Therefore, after completing one information report, it is necessary to obtain the traces of the hazardous chemical vehicle passing through the ETC gantry, toll collection system and monitoring system installed on the highway, and compare them with the prescribed route. That is, the marking and reporting module will match the highway driving trajectory of the hazardous chemical vehicle obtained based on the highway big data with the prescribed route to determine whether the highway driving trajectory of the hazardous chemical vehicle is consistent with the prescribed route. If not, it means that the hazardous chemical vehicle did not travel according to the prescribed route, and the hazardous chemical vehicle will be marked as a vehicle with abnormal trajectory, and a second information report will be made.

[0063] Furthermore, when the GPS status judgment result is normal, indicating that the GPS device of the hazardous chemical vehicle is currently in the on-state, the annotation reporting module extracts the GPS driving trajectory of the hazardous chemical vehicle based on the GPS data obtained by the GPS device of the hazardous chemical vehicle. The GPS driving trajectory of the hazardous chemical vehicle is matched with the highway driving trajectory of the hazardous chemical vehicle to determine whether the GPS driving trajectory of the hazardous chemical vehicle is consistent with the highway driving trajectory captured by the ETC gantry, toll collection system, and monitoring system installed on the highway. If inconsistent, it indicates that the actual installation location of the GPS device of the hazardous chemical vehicle may be suspicious.

[0064] For example, if hazardous chemical vehicle A maliciously removes its GPS device and installs it on vehicle B, while vehicle B follows the designated hazardous chemical transport route, vehicle A, which is actually carrying hazardous chemicals, does not follow the designated route. The GPS trajectory of hazardous chemical vehicle A is inconsistent with its actual trajectory. In this case, based solely on its GPS trajectory, it is impossible to determine that hazardous chemical vehicle A has violated regulations. Therefore, by matching the GPS trajectory of hazardous chemical vehicles with their highway trajectories, we can prevent hazardous chemical vehicles from evading regulations and other violations.

[0065] When it is determined that the GPS driving trajectory of the hazardous chemical vehicle is inconsistent with the highway driving trajectory, the marking and reporting module marks the hazardous chemical vehicle as a vehicle with abnormal trajectory and reports the information of the vehicle with abnormal trajectory.

[0066] Relevant departments may impose different degrees of punishment on hazardous chemical vehicles that violate regulations based on the number of times information is reported. For example, when a hazardous chemical vehicle is only reported once, the relevant departments may issue a warning or a minor penalty. When a hazardous chemical vehicle is reported twice, it indicates that the GPS of the hazardous chemical vehicle is abnormal and it has not been driven according to the prescribed route, which means there are two violations. The relevant departments may impose heavier penalties on hazardous chemical vehicles that violate regulations multiple times based on the number of times information is reported.

[0067] After the vehicle is labeled, the corresponding hazardous chemical vehicle driving information is obtained. In practice, this vehicle driving information can be obtained through various channels, such as the electronic waybill system archived by transportation departments or from waybill information backed up by transportation companies. Vehicle driving information includes but is not limited to the license plate, vehicle company, driver profile, escort profile, and hazardous chemical information, as well as the driving trajectory obtained above.

[0068] After obtaining the driving information of the marked vehicle, it will be reported to the relevant departments in an automatic push manner, so that the relevant departments can formulate corresponding plans, take corrective measures quickly, conduct on-site inspections of the hazardous chemical vehicles that have violated the regulations, and reduce safety hazards.

[0069] The present invention acquires and analyzes the GPS data and highway driving trajectory of hazardous chemical vehicles based on highway big data, determines whether the vehicles have violated regulations, marks the violating vehicles, and reports the information of the violating vehicles. This realizes real-time monitoring and timely correction of hazardous chemical vehicles on highways, improves monitoring efficiency, and strengthens the management of hazardous chemical vehicle transportation.
