Description

Technical Field

[0001] This invention relates to the field of vehicle-road cooperative technology, and in particular to a method, apparatus and vehicle-road cooperative platform for updating vehicle terminal registration information. Background Technology

[0002] Intelligent Vehicle Infrastructure Cooperative Systems (IVICS), or simply vehicle-road cooperative systems, represent the latest development direction of Intelligent Traffic Systems (ITS). IVICS utilizes advanced wireless communication and next-generation internet technologies to implement comprehensive, real-time dynamic information exchange between vehicles and infrastructure. Based on the collection and fusion of dynamic traffic information across all times and spaces, it conducts active vehicle safety control and cooperative road management, fully realizing effective collaboration between people, vehicles, and roads. This ensures traffic safety, improves traffic efficiency, and ultimately forms a safe, efficient, and environmentally friendly road traffic system.

[0003] In the vehicle-road cooperative system, the vehicle-road cooperative platform can communicate with the vehicle terminal through cellular communication network and / or vehicle to everything (V2X) network to realize the reporting of vehicle information and the broadcasting of platform information. The transmitted information mainly includes road condition information and vehicle status information, and acquires vehicle position, heading angle, longitudinal speed, throttle, brake, turn signal data, etc., to realize data acquisition, traffic flow statistics, background management and system control, and realize a series of safety warning, autonomous driving and traffic management applications.

[0004] Among them, the On Board Unit (OBU) can access the vehicle-road cooperative platform from the base station via the cellular communication network, or it can access the vehicle-road cooperative platform from the Road Side Unit (RSU) via the V2X network. In addition to dedicated terminals such as OBU, users can also use mobile phones or PADs as terminals, install APP and use vehicle-road cooperative applications. Mobile phones or PADs can access the vehicle-road cooperative platform from the base station via the cellular communication network.

[0005] In vehicle-road cooperative applications, the terminals are all in-vehicle, so each terminal has a corresponding license plate number. To facilitate the daily management of the management personnel, the vehicle-road cooperative platform will register the vehicle's license plate number in the vehicle-road cooperative platform.

[0006] In existing technologies, vehicle license plate numbers registered on vehicle-road cooperative platforms are manually entered during OBU network access or APP registration. Therefore, in actual use, there is a problem of low accuracy in the registration of license plate numbers corresponding to vehicle terminals in the vehicle terminal registration information.

[0118] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0119] This invention addresses the problem of low accuracy in the registration of license plate numbers corresponding to vehicle terminals in existing technologies by providing a method, apparatus, and vehicle-road cooperative platform for updating vehicle terminal registration information.

[0120] like Figure 1 As shown, this embodiment of the invention provides a method for updating registration information of a vehicle-mounted terminal, applied to a vehicle-road cooperative platform. The method includes:

[0121] Step 101: Obtain the first vehicle information sent by the vehicle terminal and the second vehicle information sent by the roadside equipment; wherein, the first vehicle information includes the vehicle terminal identification, the first vehicle location and the acquisition time of the first vehicle location; the second vehicle information includes the target license plate number, the second vehicle location and the detection time of the second vehicle location.

[0122] It should be noted that the vehicle terminal registration information update method provided in this embodiment of the invention is applicable to vehicle-road cooperative scenarios such as highways and urban roads.

[0123] This invention provides a vehicle-mounted terminal registration information update system. Figure 2 This is a schematic diagram of the vehicle-mounted terminal registration information update system. The system includes several parts: vehicle-mounted terminal, roadside equipment, cellular communication network, high-precision service system, aggregation switch, vehicle-road cooperative platform, and satellite system. The specific functions of each component are as follows:

[0124] The vehicle-mounted terminal is used to receive satellite positioning signals sent by the satellite system and high-precision positioning service information sent by the high-precision service system, calculate the high-precision location information of the vehicle-mounted terminal, and report the real-time high-precision location information (first vehicle information) to the vehicle-road cooperative platform. The vehicle-mounted terminal can communicate with roadside equipment through the PC5 interface, and can also communicate with the cellular communication network through the Uu interface.

[0125] Roadside equipment refers to equipment installed on the roadside, including roadside units (RSUs), sensing devices, computing units, and active Ethernet (Power Over Ethernet, PoE) switches. It is mainly used for sensing roadside information, sensing data fusion, communication with on-board equipment (such as on-board positioning terminals), and access to vehicle-road cooperative platforms.

[0126] The RSU is mainly used for communication with the vehicle terminal. The communication content includes the access of the vehicle equipment and the vehicle's location information. The RSU can use Dedicated Short Range Communication (DSRC) and / or Long Term Evolution-Vehicle (LTE-V) technology to communicate with the vehicle terminal equipment traveling on the highway. Multiple RSUs will be deployed along the highway.

[0127] Sensing devices include cameras, lidar, millimeter-wave radar, etc., and are mainly used for roadside video acquisition, license plate recognition, object perception, and event perception.

[0128] The computing unit calculates the license plate numbers of vehicles, objects, events and their corresponding real-time locations on the roadside based on the data collected by the sensing devices. Roadside objects include vehicle license plate numbers, pedestrians, and spilled materials.

[0129] In this embodiment of the invention, the sensing device and computing unit must at least have the ability to sense and recognize license plate numbers, while other capabilities are mainly used for various applications of vehicle-road cooperation.

[0130] PoE switches provide network transmission and power supply for roadside equipment such as RSUs, sensing devices, and computing units. These roadside devices connect to the aggregation switch through PoE switches to achieve interoperability with the vehicle-road cooperative platform.

[0131] Cellular communication networks refer to existing mobile communication networks, which include base stations and core networks to provide communication services for vehicle-mounted terminals on road sections. Vehicle-mounted terminals can communicate with vehicle-road cooperative platforms through cellular communication networks. Cellular communication networks include, but are not limited to, typical mobile communication networks such as 2G, 3G, 4G, and 5G.

[0132] The high-precision service system is used to provide high-precision positioning services to vehicle terminals, and includes ground reference stations and a high-precision positioning platform.

[0133] Among them, the ground reference station conducts long-term continuous observation of satellite positioning signals, and the observation data is transmitted to the high-precision positioning platform in real time or at regular intervals by communication facilities for the calculation of differential positioning data. The ground reference station is usually continuously covered, and the distance between the stations is between tens of kilometers and hundreds of kilometers.

[0134] The high-precision positioning platform is used to solve the observation data of each ground reference station, and calculate the differential positioning information from the observed data for the vehicle terminal to perform position calculation.

[0135] Aggregation switches are used to aggregate transmissions from various networks. They can aggregate the transmissions from cellular communication networks and / or roadside equipment to the vehicle-road cooperative platform, enabling information exchange between the cellular communication networks and / or roadside equipment and the vehicle-road cooperative platform.

[0136] The vehicle-road cooperative platform is used to provide vehicle cooperative applications and manage vehicle terminals. The vehicle-road cooperative platform includes a business management module, a location computing module, and an application service module.

[0137] The business management module manages the vehicle terminal registration information table connected to the vehicle-road cooperative platform. This table includes the vehicle terminal identity document (ID), terminal type, license plate number, vehicle detection location (second vehicle location), vehicle location detection time, and vehicle terminal registration method. The vehicle terminal registration information table is shown in Table 1 below.

[0138] Table 1 Vehicle Terminal Registration Information Table

[0139]

[0140] It should be noted that the vehicle terminal ID in the table above is just an example and can be customized according to the design numbering rules; the vehicle terminal type includes, but is not limited to, OBU and mobile terminals using APP; the license plate number is a motor vehicle license plate number that conforms to the national license plate number standard; the vehicle location detection time is the time when the vehicle location was detected; the vehicle terminal registration method is the method of updating the vehicle terminal pole ID, which usually includes manual registration, terminal reporting, roadside detection and other methods.

[0141] The location calculation module is used to compare the location reported by the vehicle terminal with the vehicle location detected by the roadside. That is, to compare the first vehicle location and the second vehicle location, to determine the vehicle with the same location reported by the vehicle terminal and detected by the roadside at the same time point, and has the ability to record the vehicle terminal ID that appears multiple times at the same time point within a period of time.

[0142] The application service module is used to provide various vehicle-road cooperative applications to the vehicle terminal, mainly to provide the complete application functions of the vehicle-road cooperative platform.

[0143] A satellite system refers to a device in a satellite positioning system that transmits satellite positioning signals to provide the reference signals required for positioning of vehicle-mounted terminals.

[0144] In this step, the vehicle-mounted terminal obtains its high-precision location information (first vehicle information) using satellite systems and high-precision service systems. This positioning method is a conventional high-precision positioning method, where the high-precision positioning system provides differential information to the positioning terminal, enabling the positioning terminal to calculate the vehicle's high-precision location information using satellite signals and differential information. The vehicle-mounted terminal acts as the positioning terminal for the high-precision positioning system. The vehicle-mounted terminal continuously uploads the first vehicle information to the vehicle-road cooperative platform via the network. The first vehicle information uploaded by the vehicle-mounted terminal includes at least the vehicle-mounted terminal ID, vehicle-mounted terminal type, vehicle location information (first vehicle location), and a timestamp of the location information acquisition (the acquisition time of the first vehicle location).

[0145] Roadside equipment continuously monitors roadside information. When a roadside vehicle is detected, it acquires vehicle information (second vehicle information) such as the vehicle's license plate number, location (second vehicle location), and detection time (detection time of the second vehicle's location). The license plate number is typically captured by a camera, the vehicle's location is detected by the roadside equipment, and the detection time is the timestamp of the collected information. The roadside equipment then sends the acquired second vehicle information to the vehicle-road cooperative platform.

[0146] The target license plate number is one of the license plate numbers.

[0147] Step 102: Update the vehicle terminal registration information according to the first correspondence between the first vehicle location and the second vehicle location, and the second correspondence between the acquisition time of the first vehicle location and the detection time of the second vehicle location;

[0148] The vehicle terminal registration information includes the license plate number and the vehicle terminal information corresponding to the license plate number;

[0149] The vehicle-mounted terminal information includes at least one of the following:

[0150] Vehicle terminal identification;

[0151] Vehicle terminal type;

[0152] The second vehicle location corresponding to the vehicle terminal identification identifier;

[0153] The detection time for the second vehicle's location;

[0154] Vehicle-mounted terminal registration method.

[0155] In this step, the vehicle-road cooperative platform compares the first vehicle location reported by the vehicle terminal with the second vehicle location detected by the roadside equipment, and updates the vehicle terminal registration information based on the collection time of the first vehicle location and the detection time of the second vehicle location. This includes updating the license plate number and the corresponding vehicle terminal ID, vehicle terminal type, vehicle location corresponding to the vehicle terminal, vehicle terminal location detection time, and vehicle terminal registration method.

[0156] The embodiments of the present invention improve the efficiency of license plate registration and the accuracy of the registration of license plate numbers corresponding to vehicle terminals in the vehicle terminal registration information.

[0157] The process of updating the vehicle terminal registration information is explained in detail below:

[0158] Optionally, updating the vehicle terminal registration information based on the first correspondence between the first vehicle location and the second vehicle location, and the second correspondence between the acquisition time of the first vehicle location and the detection time of the second vehicle location, includes:

[0159] Based on the first correspondence and the second correspondence, query the number of first vehicle terminal identity identifiers corresponding to the target license plate number in the first vehicle information;

[0160] If the first vehicle terminal identity identifier is not found in the first vehicle information, the target vehicle is determined to be a non-connected vehicle; or, if one first vehicle terminal identity identifier exists in the first vehicle information, the detection time of the current vehicle location corresponding to the target license plate number in the vehicle terminal registration information is updated to the detection time of the second vehicle location, and the vehicle terminal registration method corresponding to the target license plate number is updated to roadside detection; or, if multiple first vehicle terminal identity identifiers exist in the first vehicle information, the first sub-vehicle terminal identity identifier recorded in the vehicle terminal registration information that overlaps with the current vehicle terminal identity identifier corresponding to the target license plate number is queried from the first vehicle terminal identity identifiers, and the vehicle terminal information corresponding to the target license plate number in the vehicle terminal registration information is updated according to the first sub-vehicle terminal identity identifier.

[0161] The target vehicle is the vehicle corresponding to the target license plate number.

[0162] The vehicle-road cooperative platform's location calculation module, based on the first correspondence between the locations of the first and second vehicles, and the second correspondence between the acquisition time of the first vehicle's location and the detection time of the second vehicle's location, determines whether any on-board terminal reports the location of a first vehicle with the same or similar location as the second vehicle's location within a certain period of the detection time of the second vehicle's location corresponding to the target license plate number. If not, it determines that the target vehicle corresponding to the target license plate number is currently a non-connected vehicle. Specifically, if no on-board terminal reports the location and time of the second vehicle's location corresponding to the target license plate number during the detection time, it indicates that the target vehicle corresponding to the target license plate number is currently not a connected vehicle. If, within a certain period of the detection time of the second vehicle's location corresponding to the target license plate number, an on-board terminal (corresponding to a first on-board terminal identity) reports the location of a first vehicle with the same or similar location as the second vehicle's location, it indicates that the on-board terminal corresponding to the on-board terminal ID of the target license plate number registered in the on-board terminal registration information also reported the location and time of the first vehicle's location. The vehicle information indicates that the association between the vehicle terminal and the target license plate number recorded in the vehicle terminal registration information table is correct. At this time, the target license plate number information corresponding to the detected vehicle terminal ID is the latest. At this time, the detection time and vehicle terminal registration method fields of the current vehicle location in the vehicle terminal registration information table can be updated. Among them, the detection time of the second vehicle terminal is the latest detection time of the second vehicle location, and the vehicle terminal registration method is roadside detection. If within a certain period of the detection time of the second vehicle location corresponding to the target license plate number, two or more vehicle terminals (corresponding to multiple first vehicle terminal identity identifiers) report the first vehicle location with the same or similar location as the second vehicle location, then the judgment is continued among the two or more vehicle terminals. That is, the first sub-vehicle terminal identity identifier recorded in the vehicle terminal registration information that overlaps with the current vehicle terminal identity identifier corresponding to the target license plate number is queried in the first vehicle terminal identity identifier. Based on the first sub-vehicle terminal identity identifier, the vehicle terminal information corresponding to the target license plate number in the vehicle terminal registration information is updated.

[0163] Optionally, querying the number of first vehicle terminal identity identifiers corresponding to the target license plate number in the first vehicle information based on the first correspondence and the second correspondence includes:

[0164] Query the number of first target vehicle information that meets the first condition in the first vehicle information;

[0165] The vehicle terminal identity identifier in the first target vehicle information is determined to be the first vehicle terminal identity identifier;

[0166] The first condition includes:

[0167] The distance between the first vehicle location and the second vehicle location corresponding to the target license plate number is less than or equal to a first preset distance;

[0168] The time interval between the acquisition time of the first vehicle location and the detection time of the second vehicle location corresponding to the target license plate number is less than or equal to a first preset time interval.

[0169] It should be noted that, in this embodiment of the invention, among the vehicle terminals that report the first vehicle location and the time of the first vehicle location acquisition, it is determined whether a vehicle terminal ID (first vehicle terminal identification) can be selected that is less than a first preset distance from the second vehicle location corresponding to the target license plate number and whose detection time from the second vehicle location corresponding to the target license plate number is less than a first preset duration. If such a vehicle terminal ID can be selected, it can be considered that within a certain period of the detection time of the second vehicle location corresponding to the target license plate number, a vehicle terminal has reported a first vehicle location with the same or similar location as the second vehicle location. Otherwise, it is considered that within a certain period of the detection time of the second vehicle location corresponding to the target license plate number, no vehicle terminal has reported a first vehicle location with the same or similar location as the second vehicle location.

[0170] Preferably, the first preset distance is 30m and the first preset duration is 1s. The first preset duration is 1s because the reporting period of the vehicle terminal is 1s, and the first preset distance is 30m because a vehicle traveling at 100km / h can travel nearly 30m in 1s.

[0171] It should also be noted that the business management module of the vehicle-road cooperative platform will use the license plate number as an index to record the vehicle terminal ID (associated vehicle terminal ID) of the vehicle terminal that reports the location of the first vehicle and the collection time of the first vehicle location, and the distance between the vehicle terminal and the location of the second vehicle corresponding to the license plate number is less than a first preset distance, and the detection time between the vehicle terminal and the location of the second vehicle corresponding to the license plate number is less than a first preset duration. The specific records are shown in Table 2 below. This table will record the vehicle terminal information associated with each time the license plate number is identified.

[0172] Table 2 is the associated vehicle terminal information table.

[0173]

[0174] Furthermore, after determining that the target vehicle is a non-connected vehicle when the first vehicle terminal identification identifier is not found in the first vehicle information, the method further includes:

[0175] The target license plate number and the corresponding vehicle terminal information are deleted from the vehicle terminal registration information.

[0176] If the target license plate number is determined to be a non-connected vehicle, then the target license plate number is queried in the vehicle terminal registration information. If the target license plate number is found, it means that the target vehicle previously had a vehicle terminal, but now there is no corresponding vehicle terminal reporting information, indicating that the target vehicle is no longer using a vehicle terminal. Therefore, the target license plate number and the corresponding vehicle terminal information should be deleted from the vehicle terminal registration information table. If the target license plate number is not found, then this process ends. The target vehicle corresponding to the target license plate number detected by the roadside equipment in this conditional branch is actually a non-connected vehicle. Thus, this process ends. If the roadside equipment detects the target license plate number again in subsequent operations, the corresponding process will be run again according to the actual conditions.

[0177] Optionally, the system queries the first vehicle terminal identity identifier recorded in the vehicle terminal registration information that overlaps with the current vehicle terminal identity identifier corresponding to the target license plate number from the first vehicle terminal identity identifier, and updates the vehicle terminal information corresponding to the target license plate number in the vehicle terminal registration information according to the first sub-vehicle terminal identity identifier, including:

[0178] If the first vehicle terminal identity identifier contains a first sub-vehicle terminal identity identifier that is recorded in the vehicle terminal registration information and overlaps with the current vehicle terminal identity identifier corresponding to the target license plate number, the current vehicle terminal information corresponding to the target license plate number recorded in the vehicle terminal registration information shall be updated to the first vehicle terminal information.

[0179] The first vehicle terminal information includes at least one of the following:

[0180] First vehicle-mounted terminal identification;

[0181] First type of vehicle-mounted terminal;

[0182] The location of the second vehicle corresponding to the identity identifier of the first sub-vehicle terminal;

[0183] The detection time for the second vehicle's location;

[0184] The first method for registering the vehicle-mounted terminal.

[0185] In this process, the vehicle-road cooperative platform determines whether there is a first sub-vehicle terminal identity identifier that is a recorded vehicle terminal ID in the first vehicle terminal identity identifier. If so, it means that the license plate number corresponding to the first sub-vehicle terminal identity identifier registered in the vehicle terminal registration information table does not match the target license plate number, which may be due to vehicle terminal relocation. Therefore, the recorded vehicle terminal ID, as well as its corresponding license plate number and vehicle terminal information, which is the entire row of information corresponding to a sequence number in Table 2, is deleted. The association between the target vehicle number and the first vehicle terminal information corresponding to the first sub-vehicle terminal identity identifier is also recorded, which is the entire row of information corresponding to a sequence number in Table 2.

[0186] Optionally, after updating the current vehicle terminal information corresponding to the target license plate number recorded in the vehicle terminal registration information to the first vehicle terminal information, the method further includes:

[0187] Delete the current vehicle terminal information corresponding to the target license plate number from the vehicle terminal registration information;

[0188] The current vehicle terminal information includes:

[0189] Current vehicle terminal identification;

[0190] Current vehicle terminal type;

[0191] The second vehicle location corresponding to the current vehicle terminal identity identifier;

[0192] The detection time for the second vehicle's location;

[0193] Current vehicle terminal registration method.

[0194] It should be noted that, since the vehicle-road cooperative platform determines that the first sub-vehicle terminal identity identifier in the first vehicle terminal identity identifier is a vehicle terminal ID that has already been recorded, the association between the target vehicle number and the first vehicle terminal information corresponding to the first sub-vehicle terminal identity identifier is recorded. This is also the entire row of information corresponding to a sequence number in Table 2. Correspondingly, the original vehicle terminal information (current vehicle terminal information) corresponding to the target license plate number is also deleted.

[0195] Furthermore, the method also includes:

[0196] If the first vehicle terminal identity does not exist in the vehicle terminal registration information and the vehicle terminal identity overlaps with the current vehicle terminal identity corresponding to the target license plate number, the target license plate number and the second vehicle terminal information corresponding to the target license plate number shall be recorded in the vehicle terminal registration information.

[0197] The second vehicle-mounted terminal information includes at least one of the following:

[0198] First vehicle-mounted terminal identification;

[0199] First type of vehicle-mounted terminal;

[0200] The location of the second vehicle corresponding to the identity identifier of the first vehicle terminal;

[0201] The detection time for the second vehicle's location;

[0202] The first vehicle-mounted terminal registration method.

[0203] If the vehicle-road cooperative platform determines that none of the vehicle terminal identity identifiers in the first vehicle terminal identity identifier is a recorded vehicle terminal ID, then it records the association between the target license plate number and the second vehicle terminal information corresponding to the first vehicle terminal identity identifier, and the process ends.

[0204] It should be noted that if the target license plate number is not recorded in the vehicle terminal registration information, it means that the target license plate number was not registered when the vehicle terminal entered the network. In this case, the vehicle-road cooperative platform cannot determine which vehicle terminal corresponds to the target license plate number. Even if a vehicle terminal passes through the same location at the same time as the target license plate number is detected, the association between the vehicle terminal and the target license plate number cannot be determined for the time being. Therefore, there is a possibility that a vehicle equipped with a vehicle terminal happens to pass by at the same time as the target license plate number is detected. Especially when the traffic flow of connected vehicles is relatively large, it is necessary to further observe whether the license plate number and the same vehicle terminal happen to appear in the same location and at the same time.

[0205] In this conditional branch, the target license plate number detected by the roadside equipment can only initially record the association between the target license plate number and the second vehicle terminal information corresponding to the first vehicle terminal identification, so as to facilitate further observation and judgment. At this point, the process ends. If the roadside equipment detects the target license plate number again in subsequent operations, the corresponding process will be run again according to the actual conditions.

[0206] Optionally, after updating the current vehicle terminal information corresponding to the target license plate number recorded in the vehicle terminal registration information to the first vehicle terminal information, the method further includes:

[0207] If a first target vehicle terminal identity identifier in the first sub-vehicle terminal identity identifier is a first target vehicle terminal identity identifier that has been recorded a preset number of times in the vehicle terminal registration information and overlaps with the current vehicle terminal identity identifier corresponding to the target license plate number, then the current vehicle terminal identity identifier corresponding to the target license plate number in the vehicle terminal registration information will be updated to the first target vehicle terminal identity identifier.

[0208] If multiple first target vehicle terminal identifiers in the first sub-vehicle terminal identifier are recorded consecutively a preset number of times in the vehicle terminal registration information, and overlap with the current vehicle terminal identifier corresponding to the target license plate number, then the target license plate number and the third vehicle terminal information corresponding to the target license plate number are recorded in the vehicle terminal registration information; the third vehicle terminal information includes at least one of the following: first target vehicle terminal identifier; first target vehicle terminal type; second vehicle location corresponding to the first target vehicle terminal identifier; second vehicle location acquisition time; first target vehicle terminal registration method;

[0209] If none of the vehicle terminal identity identifiers in the first sub-vehicle terminal identity identifiers have been recorded a consecutive preset number of times in the vehicle terminal registration information, and if they overlap with the current vehicle terminal identity identifier corresponding to the target license plate number, then the vehicle terminal information corresponding to the target license plate number most recently recorded in the vehicle terminal registration information is updated to the fourth vehicle terminal information; the fourth vehicle terminal information includes at least one of the following: a second target vehicle terminal identity identifier; a second target vehicle terminal type; a second vehicle location corresponding to the second target vehicle terminal identity identifier; a second vehicle location acquisition time; and a second target vehicle terminal registration method; wherein the second target vehicle terminal identity identifier is the most recently acquired vehicle terminal identity identifier in the first sub-vehicle terminal identity identifiers; the second target vehicle terminal type is the type of vehicle terminal corresponding to the second target vehicle terminal identity identifier; and the second target vehicle terminal registration method is the method of registering the second target vehicle terminal in the vehicle registration information.

[0210] In this process, it is determined whether there is a first target vehicle-mounted terminal identity in the first sub vehicle-mounted terminal identities that is the only vehicle-mounted terminal identity corresponding to the target license plate number in multiple records. If so, it is considered that the target license plate number is associated with the vehicle-mounted terminal corresponding to the first target vehicle-mounted terminal identity. Taking the records in Table 2 as an example, when the license plate number "Shanghai A·12345" is recorded for the second time in the associated vehicle-mounted terminal information table, the service management module will compare whether there is a unique vehicle-mounted terminal ID corresponding to the license plate number "Shanghai A·12345" in each vehicle-mounted terminal ID record in this table. For example, it can be obtained by comparing the data recorded in Table 2 that there is 1 vehicle-mounted terminal ID of 00001234, and when the license plate number is detected multiple times, there is only 1 vehicle-mounted terminal that appears. Then it can be determined that the license plate number is associated with the vehicle-mounted terminal corresponding to this vehicle-mounted terminal ID. After that, the vehicle-mounted terminal information corresponding to the target license plate number in the vehicle-mounted terminal registration information table is updated, and all associated vehicle-mounted terminal IDs corresponding to the target license plate number are deleted, and this process ends. Specifically, after determining the association between the target license plate number and the vehicle-mounted terminal corresponding to the first target vehicle-mounted terminal identity, the current vehicle-mounted terminal identity corresponding to the target license plate number in the vehicle-mounted terminal registration information is updated to the first target vehicle-mounted terminal identity, and the vehicle position recorded in the vehicle-mounted terminal registration information is updated to the second vehicle position corresponding to the first target vehicle-mounted terminal identity, the detection time of the vehicle position is updated to the detection time of the second vehicle position, and the vehicle-mounted terminal registration method is updated to roadside detection. The target license plate number detected by the roadside device this time updates the vehicle-mounted terminal registration information table in this conditional branch, and至此本次流程结束。

[0211] Among them, the records in the associated vehicle-mounted terminal information table corresponding to the target license plate number are deleted because a corresponding vehicle-mounted terminal has been matched for it and the association relationship has been saved in the vehicle-mounted terminal information registration form, and it can be directly used later. Only when the vehicle-mounted terminal is relocated, this method is used again for vehicle-mounted terminal matching.

[0212] It should be noted that the original text seems to have a part that says "至此本次流程结束" which is not fully translated in the above due to the unclear meaning. You may need to check and clarify this part for a more accurate translation.The determination is made as follows: among the first sub-vehicle terminal identity identifiers, there are multiple first target vehicle terminal identity identifiers that are vehicle terminal identity identifiers corresponding to the target license plate number in multiple records; and there is also the case where none of the vehicle terminal identity identifiers among the first sub-vehicle terminal identity identifiers are vehicle terminal identity identifiers corresponding to the target license plate number in multiple records. Specifically, if none of the vehicle terminal identity identifiers in the first sub-vehicle terminal identity identifiers are the vehicle terminal identity identifiers corresponding to the target license plate number in multiple records, it means that none of the vehicle terminal identity identifiers in the previous records are truly associated with the license plate number. Therefore, the most recently obtained association relationship can be used to replace the most recent association relationship, that is, to replace the most recent record in Table 2 for the license plate number in terms of time. If there are multiple first target vehicle terminal identity identifiers in the first sub-vehicle terminal identity identifiers that are the vehicle terminal identity identifiers corresponding to the target license plate number in multiple records, it means that at least two connected vehicles appeared at the same time in the license plate number detection location in these records. In this case, it is impossible to uniquely determine the associated vehicle terminal identity identifier. Only by matching the roadside detection results at another location can we continue to do so until a unique vehicle terminal identity identifier corresponding to the license plate number appears in each vehicle terminal ID record. Otherwise, the business management module will continue to record the association relationship between the license plate number and the vehicle terminal identity identifier.

[0213] If none of the vehicle terminal identifiers in the first sub-vehicle terminal identifiers are the vehicle terminal identifiers corresponding to the target license plate number in multiple records, then the most recent record is replaced by the association between the target license plate number and the latest vehicle terminal information (fourth vehicle terminal information).

[0214] If the first sub-vehicle terminal identity is one of multiple first target vehicle terminal identity identifiers that corresponds to the target license plate number in multiple records, then the association between the target license plate number and the vehicle terminal information corresponding to the first sub-vehicle terminal identity identifier is recorded. In other words, the associated vehicle terminal information table corresponding to the target license plate number is updated to prepare for further comparison and matching to find a unique vehicle terminal identity identifier. This concludes the process.

[0215] The following is combined Figure 3 This section details the specific process for updating the registration information on the vehicle-mounted terminal.

[0216] Step 301: The vehicle-mounted terminal obtains first vehicle information using a satellite system and a high-precision service system; Step 302: The vehicle-mounted terminal continuously uploads the first vehicle information to the vehicle-road cooperative platform via the network; Step 303: The roadside equipment continuously detects roadside information, and when a roadside vehicle is detected, it obtains second vehicle information through the roadside unit; Step 304: The roadside equipment uploads the second vehicle information to the vehicle-road cooperative platform via the network; Step 305: The vehicle-road cooperative platform detects whether the first vehicle information contains a first vehicle-mounted terminal identity identifier whose detection time from the location of the second vehicle corresponding to the target license plate number is less than a first preset time and whose distance from the location of the second vehicle corresponding to the target license plate number is less than a first preset distance; if step 305... If the judgment result is negative, proceed to step 306: determine that the target vehicle corresponding to the target license plate number is a non-connected vehicle; then, proceed to step 307: query the target license plate number in the vehicle terminal registration information; if found, proceed to step 308: delete the target license plate number and the corresponding vehicle terminal information; if not found, end the process; if the judgment result of step 305 is positive, proceed to step 309: query whether there is a unique first sub-vehicle terminal identity identifier in the first vehicle terminal identity identifier, which is the identity identifier corresponding to the recorded target license plate number; if the execution result of step 309 is positive, proceed to step 310: determine the vehicle terminal identity identifier corresponding to the target license plate number in the vehicle terminal registration information. If the first sub-vehicle terminal identity is obtained, this process ends. If the result of step 309 is negative, then proceed to step 311: check if there are multiple first sub-vehicle terminal identity identifiers among the first vehicle terminal identity identifiers, and if they are the identity identifiers corresponding to the recorded target license plate number. If the result of step 311 is negative, then proceed to step 312: update the recorded current vehicle terminal information corresponding to the target license plate number to the second vehicle terminal information corresponding to the first vehicle terminal identity identifier. If the result of step 311 is positive, then proceed to step 313: update the recorded current vehicle terminal information corresponding to the target license plate number to the first vehicle terminal information corresponding to the first sub-vehicle terminal identity identifier, and delete the target license plate number. Current vehicle terminal information; then execute step 314: query whether there is a unique first target vehicle terminal identity that corresponds to the target license plate number recorded multiple times in the first sub-vehicle terminal identity identifier; if the result of step 314 is yes, then execute step 315: determine that the vehicle terminal identity that corresponds to the target license plate number in the vehicle terminal registration information is the first target vehicle terminal identity identifier, delete the current vehicle terminal identity identifier corresponding to the target license plate number, and this process ends; if the result of step 314 is no, then execute step 316: query whether there are multiple first target vehicle terminal identity identifiers that correspond to the target license plate number recorded multiple times in the first sub-vehicle terminal identity identifier;If the result of step 316 is negative, then proceed to step 317: update the current vehicle terminal information corresponding to the recorded target license plate number to the latest fourth vehicle terminal information; if the result of step 316 is positive, then this process ends.

[0217] The vehicle terminal information update method provided in this embodiment of the invention detects license plate numbers through roadside equipment and directly registers the detected license plate numbers into the vehicle terminal registration information through the vehicle-road cooperative platform. Therefore, this embodiment of the invention automatically completes the registration of license plate numbers through the vehicle terminal and the vehicle-road cooperative platform, replacing the manual registration method in the prior art, thereby achieving a more efficient license plate number registration function.

[0218] The license plate registration accuracy is high. This invention allows for real-time capture of license plate numbers by roadside equipment and real-time association with the vehicle-mounted terminal. This solution can promptly update the license plate number and vehicle-mounted terminal identification information in the vehicle-mounted terminal registration information even when the terminal is moved. Furthermore, the statistics are performed by the vehicle-road cooperative platform, avoiding errors and delays caused by manual registration. Therefore, compared to existing technologies, this invention offers better platform accuracy.

Therefore, all embodiments of the above-described vehicle terminal registration information updating method are applicable to this device and can achieve the same or similar technical effects.

[0271] like Figure 5 As shown, this embodiment of the invention also provides a vehicle-road cooperative platform, including: a processor 501, a memory 502, and a program stored in the memory 502 and executable on the processor 501. When the program is executed by the processor 501, it implements the above-described method for updating vehicle terminal registration information.

[0272] Optionally, it also includes a transceiver 503, which is used to receive and send data under the control of the processor 501.

[0273] Specifically, the processor 501 is used for:
