[0002] With the rapid development of intelligent transportation and vehicle networking technologies, vehicle positioning and monitoring has become an important part of modern traffic management. Accurate vehicle positioning information is of great significance for improving traffic efficiency, ensuring driving safety, and optimizing vehicle scheduling. However, in practical applications, due to the complex and variable environment of in-vehicle positioning communication systems, how to ensure the accuracy of vehicle positioning and the reliability of real-time monitoring has become an urgent problem to be solved.

[0003] Traditional vehicle positioning and monitoring methods usually rely on a single positioning channel or link.

Detailed implementation manners

[0048] To enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. According to the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts should fall within the protection scope of the present application.

[0049] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these process, method, product, or device.

[0050] Figure 1 It shows a schematic flowchart of the Beidou positioning and monitoring method for vehicles based on artificial intelligence provided by the embodiments of the present application. It should be understood that in other embodiments, the order of some steps of the Beidou positioning and monitoring method for vehicles based on artificial intelligence can be interchanged according to actual needs, or some of the steps can also be omitted or deleted. The detailed steps of the Beidou positioning and monitoring method for vehicles based on artificial intelligence are introduced as follows.

[0051] Step S110, when a Beidou positioning and monitoring task for a target vehicle in the vehicle-mounted positioning and communication system is recognized, obtain the positioning accuracy requirement information of the target vehicle. The target vehicle is any vehicle to be tracked between a first vehicle-mounted Beidou positioning node and a second vehicle-mounted Beidou positioning node, and the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node are arranged in the vehicle-mounted positioning and communication system.

[0052] In this embodiment, in a scenario, the Beidou positioning platform system receives a Beidou positioning and monitoring task request for a certain truck in the vehicle-mounted positioning and communication system, and this truck is the target vehicle mentioned in this step. At the same time of receiving the Beidou positioning and monitoring task, the Beidou positioning platform system also obtains the specific requirements of this truck for positioning accuracy. For example, it is required to achieve meter-level positioning accuracy. This positioning accuracy requirement information is set by the truck transportation company to ensure precise tracking during the cargo transportation process. The Beidou positioning platform system clearly knows that this truck is currently driving in an area equipped with a first vehicle-mounted Beidou positioning node and a second vehicle-mounted Beidou positioning node, and these two nodes are important components of the vehicle-mounted positioning and communication system.

[0053] Step S120, obtain the positioning performance information of at least one Beidou positioning and monitoring link between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node. Each Beidou positioning and monitoring link corresponds to a positioning channel between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node.

[0054] In this embodiment, in order to determine which Beidou positioning and monitoring link is most suitable for monitoring the target vehicle, the Beidou positioning platform system first needs to understand the positioning performance information of all available Beidou positioning and monitoring links between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node. These positioning performance information includes but is not limited to the positioning response time, positioning error data, etc. of each link. The Beidou positioning platform system obtains this information by sending a query request to these two vehicle-mounted Beidou positioning nodes and receiving the returned performance data. For example, a certain Beidou positioning and monitoring link may have a faster response time and lower positioning error, while another Beidou positioning and monitoring link may perform slightly worse in these aspects.

[0055] Step S130, according to the positioning performance information of each Beidou positioning and monitoring link, select a target Beidou positioning and monitoring link that matches the positioning accuracy requirement information of the target vehicle from each Beidou positioning and monitoring link.

[0056] In this embodiment, after collecting the positioning performance information of all Beidou positioning monitoring links, the Beidou positioning platform system starts to analyze this information. For example, according to the meter-level positioning accuracy required by the target vehicle, those Beidou positioning monitoring links that can meet this accuracy requirement can be screened out. For instance, if the positioning error of a certain link is within the meter level and the response time also meets the monitoring requirements, then this Beidou positioning monitoring link may be selected as the target Beidou positioning monitoring link. The Beidou positioning platform system can select the optimal one from all the qualified Beidou positioning monitoring links according to a set of algorithms or rules.

[0057] Step S140, allocate the target vehicle to the target Beidou positioning monitoring link for Beidou positioning monitoring.

[0058] Once the target Beidou positioning monitoring link is selected, the Beidou positioning platform system will allocate the target vehicle (i.e., that truck) to this target Beidou positioning monitoring link for monitoring, which means that the Beidou positioning platform system can notify the corresponding in-vehicle Beidou positioning nodes to send and receive the positioning data of the target vehicle through this selected target Beidou positioning monitoring link. From this moment on, the Beidou positioning platform system can obtain the accurate position information of the truck in real time through this high-performance target Beidou positioning monitoring link, thus meeting the precise tracking requirements of the transportation company for the position of the truck.

[0059] Based on the above steps, the embodiment of the present application identifies the Beidou positioning monitoring task of the target vehicle in the in-vehicle positioning communication system and obtains the positioning accuracy requirement information of the target vehicle in real time. At the same time, it collects the positioning performance information of at least one Beidou positioning monitoring link between the first in-vehicle Beidou positioning node and the second in-vehicle Beidou positioning node. By using this positioning accuracy requirement information and positioning performance information, it is possible to intelligently select the Beidou positioning monitoring link that best matches the positioning accuracy requirement of the target vehicle. This intelligent matching based on link performance and vehicle positioning accuracy requirement not only ensures the accuracy of positioning, but also optimizes resource allocation, improves the efficiency and response speed of the entire positioning monitoring system, and thus can achieve more accurate and efficient Beidou positioning monitoring of the target vehicle.

[0060] In a possible implementation manner, the positioning accuracy requirement information of the target vehicle includes the positioning accuracy level of the target vehicle. Step S130 may include:

[0061] Step S131, based on the positioning performance information of each Beidou positioning monitoring link, allocate different positioning performance levels to each Beidou positioning monitoring link.

[0062] Step S132: Select, from each of the Beidou positioning and monitoring links, the Beidou positioning and monitoring link whose positioning performance level matches the positioning accuracy level of the target vehicle as the target Beidou positioning and monitoring link.

[0063] In this embodiment, when the Beidou positioning platform system receives a Beidou positioning and monitoring task for a target vehicle, in addition to obtaining the basic information of the vehicle, it also pays special attention to the specific requirements of the target vehicle for positioning accuracy. In this scenario, the positioning accuracy required by the target vehicle (for example, a high-end logistics service vehicle) is clearly defined as the "high-precision level", which means that the position information of the vehicle needs to reach a very high level of accuracy for refined logistics management and customer service.

[0064] The Beidou positioning platform system will then deeply analyze the positioning performance information of each previously collected Beidou positioning and monitoring link. This positioning performance information includes key indicators such as the positioning response time and positioning error data of the Beidou positioning and monitoring link. Based on these data, the Beidou positioning platform system can conduct a comprehensive evaluation of each Beidou positioning and monitoring link and accordingly assign them to different positioning performance levels.

[0065] For example, some Beidou positioning and monitoring links are rated as the "high-performance level" because they have an extremely fast response time and extremely small positioning errors; while some other Beidou positioning and monitoring links may be classified into the "standard performance level" or "low-performance level" due to a slightly slower response or a slightly larger positioning error.

[0066] After completing the allocation of link performance levels, the Beidou positioning platform system can start looking for a Beidou positioning and monitoring link that matches the "high-precision level" required by the target vehicle. In this process, the Beidou positioning platform system can screen out all the links rated as the "high-performance level" because these links are most likely to meet the target vehicle's demand for high-precision positioning.

[0067] Finally, from the screened "high-performance level" links, the Beidou positioning platform system can select an optimal link as the "target Beidou positioning and monitoring link" based on a series of optimization algorithms (such as considerations of factors like cost, stability, and availability). This link will be used to conduct real-time and high-precision Beidou positioning and monitoring of the target vehicle.

[0068] Through the above steps, the Beidou positioning platform system can ensure that it provides monitoring services that meet the positioning accuracy requirements of the target vehicle, thereby effectively improving the efficiency of logistics management and the satisfaction of customer service.

[0069] In a possible implementation manner, the positioning performance information of any Beidou positioning and monitoring link includes the positioning response time and positioning error data. Step S131 includes:

[0070] Step S1311: Based on the positioning response time and positioning error data of each Beidou positioning and monitoring link among the various Beidou positioning and monitoring links respectively, perform positioning performance evaluation on the corresponding Beidou positioning and monitoring link, and generate the positioning performance evaluation values of the various Beidou positioning and monitoring links.

[0071] Step S1312: Based on the positioning performance evaluation values of the various Beidou positioning and monitoring links, assign different positioning performance levels to the various Beidou positioning and monitoring links.

[0072] In this embodiment, the Beidou positioning platform system will first collect positioning performance information from each of the Beidou positioning and monitoring links. This positioning performance information mainly includes positioning response time and positioning error data. For example, the average positioning response time of link A is 0.5 seconds, and the average positioning error is 2 meters; the average positioning response time of link B is 1 second, and the average positioning error is 5 meters, etc.

[0073] Next, the Beidou positioning platform system can use the collected positioning response time and positioning error data to perform positioning performance evaluation on each Beidou positioning and monitoring link. The evaluation process may involve complex algorithms, comprehensively considering the response time and error data, and giving a comprehensive evaluation value. For example, because link A has a short response time and small error, it may obtain a high evaluation value, such as 90 points; while link B may obtain a lower evaluation value, such as 70 points, because it has a longer response time and larger error.

[0074] After obtaining the positioning performance evaluation values of the various Beidou positioning and monitoring links, the Beidou positioning platform system can assign the links to different positioning performance levels according to these positioning performance evaluation values. For example, it can be set that those with an evaluation value above 85 points are of "high performance level", those with an evaluation value between 70 - 85 points are of "standard performance level", and those with an evaluation value below 70 points are of "low performance level". In this example, because the evaluation value of link A is 90 points, it is assigned to the "high performance level"; while because the evaluation value of link B is 70 points, it is assigned to the "standard performance level".

[0075] For example, assume that the Beidou positioning platform system is providing services for a logistics company. The logistics company has various types of transport vehicles, including high - speed trucks, urban delivery vehicles, etc. These vehicles all need to perform real - time position tracking through the Beidou positioning and monitoring links.

[0076] The Beidou positioning platform system first collected the positioning performance information of 5 different Beidou positioning monitoring links. After analysis, it was found that the positioning response time and positioning error data of Link 1 and Link 2 were both excellent, so their positioning performance evaluation values were relatively high. While Link 3, Link 4 and Link 5 were slightly inferior in terms of positioning response time and positioning error, so their evaluation values were relatively low.

[0077] According to the evaluation values, the Beidou positioning platform system assigns Link 1 and Link 2 to the "high-performance level", which is suitable for real-time monitoring of high-speed trucks, because these vehicles require higher positioning accuracy and faster response time to ensure driving safety. And Link 3, Link 4 and Link 5 are assigned to the "standard performance level", which is suitable for monitoring urban distribution vehicles. These vehicles drive within the city and have relatively low requirements for positioning accuracy, but still need to maintain a stable monitoring connection.

[0078] Through such an allocation method, the Beidou positioning platform system can ensure that different types of vehicles can obtain Beidou positioning monitoring services suitable for their needs.

[0079] In a possible implementation manner, the first vehicle-mounted Beidou positioning node or the second vehicle-mounted Beidou positioning node performs positioning performance detection based on a preset evaluation stage, and generates the positioning performance information of each Beidou positioning monitoring link. The candidate Beidou positioning monitoring link is any one of the Beidou positioning monitoring links between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node.

[0080] If there is a change in the positioning performance level of the candidate Beidou positioning monitoring link determined based on the positioning performance information of the candidate Beidou positioning monitoring link generated in multiple rounds, an exception notification is sent to the positioning operation and maintenance entity. Wherein, the exception notification indicates that the positioning operation and maintenance entity performs operation and maintenance on the positioning channel corresponding to the candidate Beidou positioning monitoring link.

[0081] In this embodiment, within a certain time period, the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node will perform positioning performance detection based on a preset evaluation stage. For example, this evaluation stage can be set to a fixed time period every day, such as from 3 am to 4 am, when there are fewer road vehicles and lower interference factors, which is conducive to obtaining more accurate detection data.

[0082] During the detection process, these two vehicle-mounted Beidou positioning nodes will perform positioning through different Beidou positioning monitoring links respectively, and record the positioning response time and positioning error data of each link. These data will be used as the positioning performance information of each Beidou positioning monitoring link.

[0083] The candidate Beidou positioning monitoring link is any one of the Beidou positioning monitoring links between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node. In practical applications, there may be multiple links available for selection, and each link has its unique performance and stability characteristics.

[0084] The Beidou positioning platform system can continuously monitor and record the positioning performance information of each candidate Beidou positioning monitoring link. If, after multiple rounds of detection, it is found that the positioning performance level of a certain candidate Beidou positioning monitoring link has changed significantly, such as dropping from a "high performance level" to a "low performance level", or the positioning error data suddenly increases, then the Beidou positioning platform system can determine that there is an abnormality in the positioning performance of this link.

[0085] Once the Beidou positioning platform system detects an abnormality in the positioning performance level of the candidate Beidou positioning monitoring link, it will immediately send an exception notification to the positioning operation and maintenance entity. This exception notification is an alarm signal indicating that there is a problem with the performance of a certain positioning monitoring link and requires the operation and maintenance entity to intervene and handle it.

[0086] After receiving the exception notification, the positioning operation and maintenance entity will immediately conduct inspections and repairs on the candidate Beidou positioning monitoring link with problems. This can include a series of operations such as checking hardware devices, optimizing software configurations, and adjusting signal reception strategies to ensure that the positioning performance of the link can be restored to the normal level as soon as possible.

[0087] For example, assume there is a long-haul freight truck with the first vehicle-mounted Beidou positioning node installed on it, and the second vehicle-mounted Beidou positioning node is set at the destination. They communicate through multiple Beidou positioning monitoring links. Between 3 am and 4 am one day, these two nodes conducted positioning performance detections according to the preset evaluation stage. The detection results showed that the positioning response time of one of the candidate Beidou positioning monitoring links was significantly prolonged, and the positioning error data also increased. After collecting these data, the Beidou positioning platform system analyzed and determined that the positioning performance level of this link had dropped from a "high performance level" to a "low performance level", and immediately sent an exception notification to the positioning operation and maintenance entity. After receiving the notification, the positioning operation and maintenance entity quickly inspected and repaired this link. After a series of operations, the positioning performance of the link was restored, ensuring the real-time positioning accuracy and stability of the freight truck.

[0088] In a possible implementation manner, the first vehicle-mounted Beidou positioning node or the second vehicle-mounted Beidou positioning node conducts positioning performance detections based on a preset evaluation stage and generates the positioning performance information of each Beidou positioning monitoring link. Each positioning performance level corresponds to its respective level determination strategy. The candidate Beidou positioning monitoring link is any one of the Beidou positioning monitoring links between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node.

[0089] Thus, based on the differences between the positioning performance information of the candidate Beidou positioning and monitoring links generated in the previous round and that of the candidate Beidou positioning and monitoring links generated in this round, the level determination strategies corresponding to each positioning performance level can be updated, so that by using the updated level determination strategies corresponding to each positioning performance level, the positioning performance of the candidate Beidou positioning and monitoring links can be evaluated according to the positioning performance information generated in this round.

[0090] In this embodiment, within a specific time period, such as from 2 am to 4 am every day, the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node will start the positioning performance detection program. This time period is selected because there are fewer vehicles on the road and the signal interference is relatively low, which can more accurately reflect the actual performance of the link.

[0091] During the detection process, the two vehicle-mounted Beidou positioning nodes will respectively perform positioning attempts through multiple candidate Beidou positioning and monitoring links between them, and record key data such as the positioning response time and positioning accuracy of each link. These data will serve as the positioning performance information of each Beidou positioning and monitoring link.

[0092] The Beidou positioning platform system can collect and store the positioning performance information generated in each round of detection. After each round of detection, the Beidou positioning platform system can compare and analyze the positioning performance information generated in this round with that of the previous round.

[0093] For example, the Beidou positioning platform system may find that the positioning response time of a certain candidate Beidou positioning and monitoring link in this round of detection is 0.2 seconds longer than that of the previous round, and the positioning accuracy has also decreased slightly. These difference data are crucial for subsequent strategy updates.

[0094] Based on the comparison and analysis results of the positioning performance information of the previous and this rounds, the Beidou positioning platform system can update the level determination strategies corresponding to each positioning performance level. These strategies are a series of rules and algorithms used to divide the links into different performance levels according to the positioning performance information.

[0095] If the performance of a certain link continues to decline in two rounds of detection, then the Beidou positioning platform system may adjust the level determination strategy of this link to make it easier to be classified into a lower performance level. Conversely, if the link performance improves, the strategy will be adjusted accordingly.

[0096] After updating the level determination strategy, the Beidou positioning platform system can immediately adopt these new strategies to evaluate the positioning performance information of the candidate Beidou positioning monitoring links generated in this round. This means that if a certain link might have been rated as a "high-performance level" under the previous strategy, but under the new strategy, due to a performance decline, it might only be rated as a "standard performance level" or lower.

[0097] For example, suppose there is a logistics vehicle that often travels in the urban-rural fringe and is equipped with a first on-vehicle Beidou positioning node. Due to the complex and changeable signal environment in this area, it is necessary to regularly evaluate and optimize the performance of the positioning monitoring link. During the early morning detection on a certain day, the Beidou positioning platform system found that the positioning performance of a certain candidate Beidou positioning monitoring link had significantly declined. By comparing and analyzing the positioning performance information of the previous and current rounds, the Beidou positioning platform system decided to update the level determination strategy for this link. The updated strategy is more stringent, requiring the link to maintain stable performance in consecutive multiple detections to be rated as a "high-performance level". In the subsequent evaluation, since this link failed to meet the requirements of the new strategy, it was downgraded to a "standard performance level". This adjustment enables the logistics vehicle to more accurately select a link with better performance when choosing a positioning monitoring link, thereby improving the accuracy and stability of positioning.

[0098] In a possible implementation manner, the first on-vehicle Beidou positioning node and the second on-vehicle Beidou positioning node come from node groups of different modules in the vehicle positioning communication system. The method further includes:

[0099] Obtain at least one positioning channel between the first on-vehicle Beidou positioning node and the second on-vehicle Beidou positioning node.

[0100] Construct a corresponding Beidou positioning monitoring link for each positioning channel between the first on-vehicle Beidou positioning node and the second on-vehicle Beidou positioning node.

[0101] In this embodiment, in the vehicle positioning communication system, there are multiple modules, and each module has a group of nodes. The first on-vehicle Beidou positioning node and the second on-vehicle Beidou positioning node respectively come from these node groups of different modules. For example, the first on-vehicle Beidou positioning node may come from the module responsible for vehicle navigation, while the second on-vehicle Beidou positioning node may come from the module responsible for vehicle monitoring and dispatching.

[0102] After determining the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node, the Beidou positioning platform system will further obtain at least one positioning channel between these two nodes. A positioning channel is a path for data transmission and communication between nodes. In this step, the Beidou positioning platform system may determine which channels are available by sending detection signals or using the built-in network discovery mechanism of the system, and evaluate the quality of these channels.

[0103] For example, the Beidou positioning platform system may find that the two nodes can be connected through multiple different wireless communication frequency bands, such as 4G, 5G, or a dedicated short-range wireless communication protocol. The Beidou positioning platform system can test the stability, latency, and bandwidth of these channels to select the most suitable channel for Beidou positioning data transmission.

[0104] After determining the available positioning channels, the Beidou positioning platform system can construct corresponding Beidou positioning monitoring links for each positioning channel between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node. This process involves configuring relevant communication parameters, such as data transmission rate, error detection, and correction mechanisms, to ensure that the link can stably transmit Beidou positioning data in various environments.

[0105] Taking a specific scenario as an example, the Beidou positioning platform system may construct a Beidou positioning monitoring link for a 4G communication channel between two nodes. In this Beidou positioning monitoring link, the Beidou positioning platform system can set appropriate data compression and encryption methods to reduce transmission latency and ensure data security. At the same time, the Beidou positioning platform system will also configure the automatic recovery mechanism of the link so that it can quickly reconnect and continue to transmit data when the communication is interrupted.

[0106] Through such steps, the Beidou positioning platform system can ensure that the data transmission between vehicle-mounted Beidou positioning nodes is both efficient and reliable, thus supporting the realization of key functions such as vehicle positioning, navigation, and monitoring.

[0107] In a possible implementation manner, the method further includes:

[0108] Obtaining the positioning performance information of each Beidou positioning monitoring link generated by the first vehicle-mounted Beidou positioning node or the second vehicle-mounted Beidou positioning node.

[0109] Among them, the positioning performance information of any one of the Beidou positioning monitoring links is obtained by the first vehicle-mounted Beidou positioning node or the second vehicle-mounted Beidou positioning node based on a preset evaluation stage for positioning performance detection of the Beidou positioning monitoring link.

[0110] In a vehicle-mounted positioning system, the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node will regularly or under specific conditions perform positioning performance detection on the Beidou positioning monitoring link between them. These detections are carried out in a preset evaluation stage to ensure the performance of the link is evaluated under similar environments and conditions.

[0111] After completing the performance detection, these vehicle-mounted Beidou positioning nodes will generate positioning performance information about each Beidou positioning monitoring link. This information can include data in multiple aspects such as the signal strength, positioning accuracy, response time, and stability of the link.

[0112] Subsequently, the Beidou positioning platform system can obtain this positioning performance information from these vehicle-mounted Beidou positioning nodes. The acquisition method may be through network transmission, such as sending this information to the Beidou positioning platform system via a wireless communication network (such as 4G, 5G, or satellite communication), or uploading data through a wired connection when the vehicle returns to the base.

[0113] For example, assume that the first vehicle-mounted Beidou positioning node performs performance detection on all Beidou positioning monitoring links between it and the second vehicle-mounted Beidou positioning node at 3 am (a preset evaluation stage when traffic flow is low and signal interference is less). After the detection is completed, the node will send the generated positioning performance information, such as signal reception quality, positioning error range, data transmission delay, etc., to the Beidou positioning platform system through the vehicle-mounted communication system.

[0114] After the Beidou positioning platform system receives this information, it will store, analyze, and process it for subsequent evaluation and optimization of the performance of the Beidou positioning monitoring link. In this way, the Beidou positioning platform system can understand the performance status of each Beidou positioning monitoring link in real time, discover potential problems in a timely manner, and take corresponding measures to ensure the stability and accuracy of the vehicle-mounted positioning system.

[0115] In a possible implementation, the candidate Beidou positioning monitoring link is any one of the Beidou positioning monitoring links between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node. The process of the first vehicle-mounted Beidou positioning node performing positioning performance detection on the candidate Beidou positioning monitoring link includes:

[0116] Sending a positioning performance detection instance to the second vehicle-mounted Beidou positioning node using the positioning channel corresponding to the candidate Beidou positioning monitoring link.

[0117] Determining the positioning performance information of the candidate Beidou positioning monitoring link based on the feedback status data of the positioning performance detection instance.

[0118] In this embodiment, when the Beidou positioning platform system determines that positioning performance detection is to be carried out, it instructs the first vehicle-mounted Beidou positioning node to start the detection process. The first vehicle-mounted Beidou positioning node will select a candidate Beidou positioning monitoring link, which is one of the numerous links between it and the second vehicle-mounted Beidou positioning node.

[0119] To detect the performance of this Beidou positioning monitoring link, the first vehicle-mounted Beidou positioning node will use the positioning channel corresponding to this link to send a positioning performance detection instance to the second vehicle-mounted Beidou positioning node. This detection instance may contain a series of test signals, timestamps, and other parameters for evaluating the link performance.

[0120] For example, assume that the first vehicle-mounted Beidou positioning node selects a candidate Beidou positioning monitoring link that communicates through a 4G network. It will send a detection instance containing test signals and timestamps to the second vehicle-mounted Beidou positioning node through the 4G positioning channel of this Beidou positioning monitoring link.

[0121] After receiving the positioning performance detection instance, the second vehicle-mounted Beidou positioning node will perform corresponding processing and send the processing results back to the first vehicle-mounted Beidou positioning node in the form of feedback status data. These feedback status data may include information such as signal reception strength, processing time, error range, etc.

[0122] After receiving these feedback status data, the first vehicle-mounted Beidou positioning node will analyze them to determine the positioning performance information of the candidate Beidou positioning monitoring link. For example, by comparing the sent and received timestamps, the transmission delay of the signal can be calculated; by analyzing the signal reception strength, the communication quality of the link can be evaluated; by the error range, the accuracy of positioning can be judged.

[0123] Suppose that after processing the detection instance, the second vehicle-mounted Beidou positioning node finds that the signal reception strength is weak, the processing time is long, and there is a certain positioning error. It will send this information back to the first vehicle-mounted Beidou positioning node as feedback status data. After receiving these data, the first vehicle-mounted Beidou positioning node will conduct a comprehensive analysis and obtain the positioning performance information of this candidate Beidou positioning monitoring link as "the communication quality is average, there is a certain positioning error, and further optimization is needed".

[0124] Through such steps, the Beidou positioning platform system can conduct a detailed detection and evaluation of the positioning performance of the candidate Beidou positioning monitoring link through the interaction between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node.

[0125] In a possible implementation manner, the positioning performance information of the candidate Beidou positioning and monitoring link includes the positioning response time. The first vehicle-mounted Beidou positioning node comes from the node group of the first module in the vehicle-mounted positioning communication system, and the second vehicle-mounted Beidou positioning node comes from the node group of the second module in the vehicle-mounted positioning communication system. A first relay device is further configured in the node group of the first module, and a second relay device is further configured in the node group of the second module.

[0126] Determining the positioning performance information of the candidate Beidou positioning and monitoring link based on the feedback status data of the positioning performance detection instance includes:

[0127] Obtain the positioning performance detection instance transmitted by the first relay device. The positioning performance detection instance of the first relay device is continuously transmitted after the first relay device obtains the positioning performance detection instance transmitted by the second relay device. The positioning performance detection instance of the second relay device is continuously transmitted after the second relay device obtains the positioning performance detection instance transmitted by the second vehicle-mounted Beidou positioning node. The positioning performance detection instance of the second vehicle-mounted Beidou positioning node is continuously transmitted after the second vehicle-mounted Beidou positioning node obtains the positioning performance detection instance transmitted by the first vehicle-mounted Beidou positioning node.

[0128] Based on the time-domain interval parameter between the time domain when the first vehicle-mounted Beidou positioning node obtains the positioning performance detection instance and the time domain when the first vehicle-mounted Beidou positioning node sends the positioning performance detection instance, determine the positioning response time.

[0129] In this embodiment, in a vehicle-mounted positioning communication system, there are two main modules: the first module and the second module. There is a group of nodes under each module. Among them, the first vehicle-mounted Beidou positioning node belongs to the node group of the first module, while the second vehicle-mounted Beidou positioning node belongs to the node group of the second module. To enhance the signal transmission ability and expand the coverage range, a first relay device is further configured in the first module, and a second relay device is configured in the second module.

[0130] The first vehicle-mounted Beidou positioning node first generates a positioning performance detection instance and sends it to the second vehicle-mounted Beidou positioning node via a wireless signal to test the performance of the candidate Beidou positioning monitoring link between the two. After receiving this detection instance, the second vehicle-mounted Beidou positioning node immediately passes it to the second relay device within the same module. After receiving the detection instance, the second relay device continues to pass it to the first relay device of the first module. The first relay device will finally send this detection instance back to the first vehicle-mounted Beidou positioning node. This series of transfer processes not only tests the direct communication performance between vehicle-mounted Beidou positioning nodes but also tests the signal transfer performance through relay devices.

[0131] When the first vehicle-mounted Beidou positioning node sends out the positioning performance detection instance, record the sending time (time domain). When the first vehicle-mounted Beidou positioning node finally receives the feedback of this detection instance through the first relay device, it will record the receiving time (time domain) again. The Beidou positioning platform system can calculate the interval between these two time domains, that is, the time difference between sending and receiving. This time difference is the positioning response time of the candidate Beidou positioning monitoring link. For example, if the first vehicle-mounted Beidou positioning node sends the detection instance at 10:00:00 and receives the detection instance sent back through the relay device at 10:00:05, then the positioning response time of this link is 5 seconds.

[0132] In this way, the Beidou positioning platform system can accurately measure the positioning response time of the candidate Beidou positioning monitoring link, thereby evaluating its performance, which is crucial for the optimization and troubleshooting of vehicle-mounted positioning communication systems.

[0133] Alternatively, in another possible implementation, determining the positioning performance information of the candidate Beidou positioning monitoring link based on the feedback status data of the positioning performance detection instance includes:

[0134] Obtain the positioning feedback signal for the positioning performance detection instance transmitted by the second vehicle-mounted Beidou positioning node using the positioning channel corresponding to the candidate Beidou positioning monitoring link.

[0135] Based on the time domain interval parameter between the time domain when the first vehicle-mounted Beidou positioning node obtains the positioning feedback signal and the time domain when the first vehicle-mounted Beidou positioning node sends the positioning performance detection instance, determine the positioning response time.

[0136] In this embodiment, in the vehicle-mounted positioning system, after the first vehicle-mounted Beidou positioning node sends a positioning performance detection instance to the second vehicle-mounted Beidou positioning node, it will wait for the feedback from the second vehicle-mounted Beidou positioning node, and this feedback is the processing result of the detection instance, which we call the positioning feedback signal.

[0137] Specifically, after receiving the positioning performance detection instance, the second vehicle-mounted Beidou positioning node will process it according to a preset process, such as parsing the data in the detection instance, executing relevant positioning algorithms, and generating a positioning feedback signal based on the processing results. This signal contains important information about the performance of the candidate Beidou positioning monitoring link, such as signal reception quality, processing duration, etc.

[0138] After generating the positioning feedback signal, the second vehicle-mounted Beidou positioning node will use the positioning channel corresponding to the candidate Beidou positioning monitoring link to transmit this signal back to the first vehicle-mounted Beidou positioning node. This transmission process is completed through a wireless communication network, which can be 4G, 5G, or other dedicated wireless communication protocols.

[0139] The Beidou positioning platform system is responsible for listening for and receiving these positioning feedback signals during this process. When the Beidou positioning platform system obtains these signals from the first vehicle-mounted Beidou positioning node, it will perform subsequent analysis and processing.

[0140] The positioning response time is one of the important indicators for evaluating the performance of the Beidou positioning monitoring link. To accurately calculate this time, the Beidou positioning platform system can record two key time points: the time domain when the first vehicle-mounted Beidou positioning node sends the positioning performance detection instance, and the time domain when the first vehicle-mounted Beidou positioning node receives the positioning feedback signal. Taking a specific scenario as an example, assume that the first vehicle-mounted Beidou positioning node sends a positioning performance detection instance at exactly 9:00 am. This instance is transmitted through the candidate Beidou positioning monitoring link, received and processed by the second vehicle-mounted Beidou positioning node. After processing, the second vehicle-mounted Beidou positioning node sends the positioning feedback signal back to the first vehicle-mounted Beidou positioning node at 9:02 am.

[0141] When the first vehicle-mounted Beidou positioning node receives this positioning feedback signal at 9:02:30 am, it will send this reception time and the previously recorded transmission time together to the Beidou positioning platform system. After receiving these data, the Beidou positioning platform system will calculate the positioning response time, which is the time difference between the reception time and the transmission time. In this example, the positioning response time is 2 minutes and 30 seconds.

[0142] The Beidou positioning platform system can comprehensively evaluate the performance of the candidate Beidou positioning monitoring link based on this positioning response time and other relevant performance data. This evaluation result can help the system administrator understand the actual performance status of the link for necessary optimization and adjustment.

[0143] Alternatively, in another possible implementation, determining the positioning performance information of the candidate Beidou positioning monitoring link based on the feedback status data of the positioning performance detection instance includes:

[0144] Obtain the positioning feedback signal transmitted by the second vehicle-mounted Beidou positioning node through the positioning channel corresponding to the candidate Beidou positioning monitoring link, where the positioning feedback signal contains the time domain in which the second vehicle-mounted Beidou positioning node obtains the positioning performance detection instance.

[0145] Based on the time domain interval parameter between the time domain in which the second vehicle-mounted Beidou positioning node obtains the positioning performance detection instance and the time domain in which the first vehicle-mounted Beidou positioning node sends the positioning performance detection instance, determine the positioning response time.

[0146] In this embodiment, during the operation of the vehicle positioning system, the first vehicle-mounted Beidou positioning node sends a positioning performance detection instance to the second vehicle-mounted Beidou positioning node to test the performance of the candidate Beidou positioning monitoring link between the two. After receiving this detection instance, the second vehicle-mounted Beidou positioning node will immediately process it and generate a positioning feedback signal. This positioning feedback signal not only contains information about the link performance but also specifically marks the accurate time (time domain) when the second vehicle-mounted Beidou positioning node obtains the positioning performance detection instance. This timestamp is very important data because it will be used for subsequent calculation of the positioning response time.

[0147] The second vehicle-mounted Beidou positioning node will use the positioning channel corresponding to the candidate Beidou positioning monitoring link to transmit this positioning feedback signal with the timestamp back to the first vehicle-mounted Beidou positioning node. The Beidou positioning platform system is responsible for obtaining this feedback signal and the time domain information therein from the first vehicle-mounted Beidou positioning node.

[0148] Once the Beidou positioning platform system obtains the positioning feedback signal and the time domain information therein, it can start calculating the positioning response time. First, the Beidou positioning platform system can view the original time domain when the first vehicle-mounted Beidou positioning node sends the positioning performance detection instance. This time is recorded by the first vehicle-mounted Beidou positioning node when sending the detection instance and then transmitted to the Beidou positioning platform system.

[0149] Next, the Beidou positioning platform system can compare the time domain in which the second vehicle-mounted Beidou positioning node obtains the positioning performance detection instance with the time domain in which the first vehicle-mounted Beidou positioning node sends the detection instance. By calculating the time difference between these two time domains, the Beidou positioning platform system can obtain the positioning response time.

[0150] For example, the process is illustrated as follows: If the first vehicle-mounted Beidou positioning node sends a positioning performance detection instance at 14:00:00 and this time is accurately recorded; then the second vehicle-mounted Beidou positioning node receives this detection instance at 14:00:05 and this time is also recorded in the positioning feedback signal. When the Beidou positioning platform system obtains this information, it will calculate that the positioning response time is 5 seconds, that is, the time interval from sending the detection to receiving the detection.

[0151] This positioning response time is one of the important indicators for evaluating the performance of the candidate Beidou positioning monitoring link, which can help the Beidou positioning platform system understand the transmission efficiency and stability of the link. By continuously monitoring and analyzing these data, the Beidou positioning platform system can timely discover problems in the link and take corresponding measures for optimization and improvement.
