DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0020] 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 are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0021] Figure 1 The flowchart of the Beidou positioning monitoring method for vehicles based on artificial intelligence provided by the embodiment of the present application is shown. It should be understood that in other embodiments, the order of some steps of the Beidou positioning monitoring method for vehicles based on artificial intelligence can be interchanged according to actual needs, or some steps thereof can be omitted or deleted. The detailed steps of the Beidou positioning monitoring method for vehicles based on artificial intelligence are described as follows.

[0022] Step S110, when a Beidou positioning monitoring task for a target vehicle in the vehicle-mounted positioning communication system is identified, the positioning accuracy requirement information of the target vehicle is obtained. 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 communication system.

[0023] In this embodiment, in one scenario, the Beidou positioning platform system receives a Beidou positioning monitoring task request for a truck in the vehicle-mounted positioning communication system. This truck is the target vehicle mentioned in this step. While receiving the Beidou positioning monitoring task, the Beidou positioning platform system also obtains the specific requirements of the truck for positioning accuracy, such as the need to achieve meter-level positioning accuracy. The positioning accuracy requirement information is set by the truck transportation company to ensure accurate tracking during cargo transportation. The Beidou positioning platform system clearly knows that the truck is currently traveling in an area equipped with a first vehicle-mounted Beidou positioning node and a second vehicle-mounted Beidou positioning node. These two nodes are important components of the vehicle-mounted positioning communication system.

[0024] Step S120, obtaining positioning performance information of at least one Beidou positioning monitoring link between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node. Each Beidou positioning monitoring link corresponds to a positioning channel between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node.

[0025] In this embodiment, in order to determine which Beidou positioning 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 monitoring links between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node, and these positioning performance information include but are not limited to the positioning response time of each link, positioning error data, etc. The Beidou positioning platform system obtains this information by sending a query request to the two vehicle-mounted Beidou positioning nodes and receiving the returned performance data. For example, a Beidou positioning monitoring link may have a faster response time and a lower positioning error, while another Beidou positioning monitoring link may perform slightly worse in these aspects.

[0026] Step S130: selecting a target Beidou positioning monitoring link that matches the positioning accuracy requirement information of the target vehicle from the various Beidou positioning monitoring links according to the positioning performance information of the various Beidou positioning monitoring links.

[0027] In this embodiment, after collecting the positioning performance information of all Beidou positioning monitoring links, the Beidou positioning platform system begins 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 example, 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 best one from all qualified Beidou positioning monitoring links based on a set of algorithms or rules.

[0028] Step S140: assigning the target vehicle to the target Beidou positioning monitoring link for Beidou positioning monitoring.

[0029] Once the target Beidou positioning monitoring link is selected, the Beidou positioning platform system will assign the target vehicle (i.e. the truck) to this target Beidou positioning monitoring link for monitoring, which means that the Beidou positioning platform system can notify the corresponding vehicle-mounted 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 precise location information of the truck in real time through this high-performance target Beidou positioning monitoring link, thereby meeting the transportation company's demand for accurate tracking of the truck's location.

[0030] Based on the above steps, the embodiment of the present application obtains the positioning accuracy requirement information of the target vehicle in real time by identifying the Beidou positioning monitoring task of the target vehicle in the vehicle-mounted positioning communication system. At the same time, the positioning performance information of at least one Beidou positioning monitoring link between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node is collected. Using these positioning accuracy requirement information and positioning performance information, the Beidou positioning monitoring link that best matches the positioning accuracy requirement of the target vehicle can be intelligently selected. This intelligent matching based on link performance and vehicle positioning accuracy requirements not only ensures the accuracy of positioning, but also optimizes resource allocation, improves the efficiency and response speed of the entire positioning monitoring system, thereby achieving more accurate and efficient Beidou positioning monitoring of the target vehicle.

[0031] In a possible implementation, the positioning accuracy requirement information of the target vehicle includes the positioning accuracy level of the target vehicle. Step S130 may include: Step S131: Based on the positioning performance information of each Beidou positioning monitoring link, each Beidou positioning monitoring link is assigned a different positioning performance level.

[0032] Step S132: Select, from the various Beidou positioning monitoring links, a Beidou positioning monitoring link whose positioning performance level matches the positioning accuracy level of the target vehicle as the target Beidou positioning monitoring link.

[0033] In this embodiment, when the Beidou positioning platform system receives the Beidou positioning monitoring task for the 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 "high-precision level", which means that the location information of the vehicle needs to reach a very high accuracy in order to carry out refined logistics management and customer service.

[0034] The Beidou positioning platform system will then conduct an in-depth analysis of the positioning performance information of each Beidou positioning monitoring link collected previously, including key indicators such as positioning response time and positioning error data of the Beidou positioning monitoring link. Based on this data, the Beidou positioning platform system can conduct a comprehensive evaluation of each Beidou positioning monitoring link and assign them to different positioning performance levels accordingly.

[0035] For example, some Beidou positioning and monitoring links are rated as "high performance level" because of their extremely fast response time and extremely small positioning error; while other Beidou positioning and monitoring links may be classified as "standard performance level" or "low performance level" because of their slightly slower response or slightly larger positioning error.

[0036] After completing the allocation of link performance levels, the BeiDou positioning platform system can start looking for BeiDou positioning monitoring links that match the "high-precision level" required by the target vehicle. In this process, the BeiDou positioning platform system can screen out all links rated as "high-performance level" because these links are most likely to meet the target vehicle's needs for high-precision positioning.

[0037] Finally, from the selected "high-performance level" links, the Beidou positioning platform system can select the best link as the "target Beidou positioning monitoring link" based on a series of optimization algorithms (such as cost, stability, availability and other factors). This link will be used for real-time, high-precision Beidou positioning monitoring of the target vehicle.

[0038] Through the above steps, the Beidou positioning platform system can ensure that the target vehicles are provided with monitoring services that meet their positioning accuracy requirements, thereby effectively improving the efficiency of logistics management and customer service satisfaction.

[0039] In a possible implementation manner, the positioning performance information of any Beidou positioning monitoring link includes positioning response time and positioning error data. Step S131 includes: Step S1311, based on the positioning response time and positioning error data of each Beidou positioning monitoring link in the said Beidou positioning monitoring links, perform positioning performance evaluation on the corresponding Beidou positioning monitoring link, and generate positioning performance evaluation values ​​of the said Beidou positioning monitoring links.

[0040] Step S1312: allocating different positioning performance levels to each Beidou positioning monitoring link based on the positioning performance evaluation value of each Beidou positioning monitoring link.

[0041] In this embodiment, the Beidou positioning platform system first collects positioning performance information from each Beidou positioning monitoring link. These positioning performance information mainly include 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.

[0042] Next, the Beidou positioning platform system can use the collected positioning response time and positioning error data to evaluate the positioning performance of each Beidou positioning monitoring link. The evaluation process may involve complex algorithms, which comprehensively consider the response time and error data to give a comprehensive evaluation value. For example, link A may get a higher evaluation value, such as 90 points, because of its short response time and small error; while link B may get a lower evaluation value, such as 70 points, because of its long response time and large error.

[0043] After obtaining the positioning performance evaluation values ​​of each Beidou positioning monitoring link, the Beidou positioning platform system can assign the link to different positioning performance levels based on these positioning performance evaluation values. For example, the evaluation value above 85 points can be set as "high performance level", 70-85 points as "standard performance level", and below 70 points as "low performance level". In this example, link A is assigned to the "high performance level" because its evaluation value is 90 points; and link B is assigned to the "standard performance level" because its evaluation value is 70 points.

[0044] For example, suppose the Beidou positioning platform system is providing services to a logistics company that has many different types of transport vehicles, including high-speed trucks, urban delivery vehicles, etc. These vehicles all need to be tracked in real time through the Beidou positioning monitoring link.

[0045] 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 performed well, so their positioning performance evaluation values ​​were high. However, link 3, link 4 and link 5 performed slightly worse in terms of positioning response time and positioning error, so their evaluation values ​​were relatively low.

[0046] According to the evaluation values, the Beidou positioning platform system assigns Link 1 and Link 2 to the "high performance level", which are suitable for real-time monitoring of high-speed trucks, because these vehicles require higher positioning accuracy and faster response time to ensure driving safety. Links 3, 4, and 5 are assigned to the "standard performance level", which are suitable for monitoring urban delivery vehicles. These vehicles travel within the city and have relatively low requirements for positioning accuracy, but still need to maintain a stable monitoring connection.

[0047] Through this distribution method, the Beidou positioning platform system can ensure that different types of vehicles can receive Beidou positioning monitoring services that suit their needs.

[0048] 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 phase, and generates positioning performance information of each Beidou positioning monitoring link. The candidate Beidou positioning monitoring link is any Beidou positioning monitoring link between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node.

[0049] If 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 is changed, an abnormal notification is sent to the positioning operation and maintenance entity, wherein the abnormal notification indicates that the positioning operation and maintenance entity operates and maintains the positioning channel corresponding to the candidate Beidou positioning monitoring link.

[0050] In this embodiment, within a certain time period, the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node will detect the positioning performance based on a preset evaluation phase. For example, this evaluation phase can be set to a fixed time period every day, such as 3 to 4 a.m., when there are fewer vehicles on the road and interference factors are low, which is conducive to obtaining more accurate detection data.

[0051] During the detection process, the 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 serve as the positioning performance information of each Beidou positioning monitoring link.

[0052] The candidate Beidou positioning monitoring link is any Beidou positioning monitoring link between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node. In practical applications, there may be multiple links to choose from, each with its own unique performance and stability characteristics.

[0053] 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 candidate Beidou positioning monitoring link has changed significantly, such as from "high performance level" to "low performance level", or the positioning error data suddenly increases, then the Beidou positioning platform system can determine that the positioning performance of the link has changed.

[0054] Once the Beidou positioning platform system detects that there is an abnormal change in the positioning performance level of a candidate Beidou positioning monitoring link, it will immediately send an abnormal notification to the positioning operation and maintenance entity. The abnormal notification is an alarm signal, indicating that there is a problem with the performance of a certain positioning monitoring link and the operation and maintenance entity needs to intervene.

[0055] After receiving the abnormality notification, the positioning operation and maintenance entity will immediately troubleshoot and repair the problematic candidate Beidou positioning monitoring link. This may include checking hardware equipment, optimizing software configuration, adjusting signal reception strategy, and other operations to ensure that the positioning performance of the link can be restored to normal levels as soon as possible.

[0056] For example, suppose there is a long-distance freight truck with a first onboard Beidou positioning node installed on the truck and a second onboard Beidou positioning node at the destination. The two communicate through multiple Beidou positioning monitoring links. At 3 to 4 a.m. on a certain day, the two nodes performed positioning performance tests according to the preset evaluation phase. The test 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 the link had dropped from "high performance level" to "low performance level", so it immediately sent an abnormal notification to the positioning operation and maintenance entity. After receiving the notification, the positioning operation and maintenance entity quickly checked and repaired the 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.

[0057] 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 phase, and generates positioning performance information of each Beidou positioning monitoring link, and each positioning performance level corresponds to a 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.

[0058] Therefore, based on the difference between the positioning performance information of the candidate Beidou positioning monitoring link generated in the previous round and the positioning performance information of the candidate Beidou positioning monitoring link generated in this round, the level determination strategy corresponding to each positioning performance level can be updated, so that the level determination strategy corresponding to each updated positioning performance level can be adopted to evaluate the positioning performance of the candidate Beidou positioning monitoring link based on the positioning performance information of the candidate Beidou positioning monitoring link generated in this round.

[0059] In this embodiment, during a specific time period, such as from 2 a.m. to 4 a.m. 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.

[0060] During the detection process, the two vehicle-mounted Beidou positioning nodes will respectively attempt to locate through multiple candidate Beidou positioning 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 monitoring link.

[0061] 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 the information in the previous round.

[0062] For example, the Beidou positioning platform system may find that the positioning response time of a candidate Beidou positioning monitoring link in this round of detection is 0.2 seconds longer than that in the previous round, and the positioning accuracy is also slightly reduced. These difference data are crucial for subsequent strategy updates.

[0063] Based on the comparative analysis results of the positioning performance information of the previous and subsequent 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.

[0064] If the performance of a link continues to decline in two rounds of testing, the BeiDou positioning platform system may adjust the level determination strategy of the link to make it easier to be classified as a lower performance level. Conversely, if the link performance improves, the strategy will be adjusted accordingly.

[0065] 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 link may be rated as "high performance level" under the previous strategy, it may only be rated as "standard performance level" or lower under the new strategy due to performance degradation.

[0066] For example, suppose there is a logistics vehicle that often travels in the urban-rural fringe, and the first vehicle-mounted Beidou positioning node is installed on the vehicle. 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. In a detection in the early morning of a certain day, the Beidou positioning platform system found that the positioning performance of a candidate Beidou positioning monitoring link had dropped significantly. By comparing and analyzing the positioning performance information of the previous and next rounds, the Beidou positioning platform system decided to update the level determination strategy of the link. The updated strategy is more stringent, requiring the link to maintain stable performance in multiple consecutive detections in order to be rated as "high performance level". In the subsequent evaluation, because the link failed to meet the requirements of the new strategy, it was downgraded to "standard performance level". This adjustment enables logistics vehicles to more accurately select links with better performance when selecting positioning monitoring links, thereby improving the accuracy and stability of positioning.

[0067] In a possible implementation, the first vehicle-mounted BeiDou positioning node and the second vehicle-mounted BeiDou positioning node are from node groups of different modules in the vehicle-mounted positioning communication system. The method further includes: Obtain at least one positioning channel between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node.

[0068] For each positioning channel between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node, a corresponding Beidou positioning monitoring link is constructed.

[0069] In this embodiment, in the vehicle-mounted positioning communication system, there are multiple modules, and each module has a group of nodes. The first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node come from the node groups of these different modules respectively. For example, the first vehicle-mounted Beidou positioning node may come from the module responsible for vehicle navigation, and the second vehicle-mounted Beidou positioning node may come from the module responsible for vehicle monitoring and scheduling.

[0070] 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 the two nodes. The positioning channel is the path for data transmission and communication between nodes. In this step, the Beidou positioning platform system may determine which channels are available and evaluate the quality of these channels by sending a detection signal or using the system's built-in network discovery mechanism.

[0071] For example, the BeiDou positioning platform system may find that two nodes can be connected through multiple different wireless communication frequency bands, such as 4G, 5G, or dedicated short-range wireless communication protocols. The BeiDou positioning platform system can test the stability, latency, and bandwidth of these channels to select the channel that is most suitable for BeiDou positioning data transmission.

[0072] After determining the available positioning channels, the Beidou positioning platform system can build a corresponding Beidou positioning monitoring link 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 mechanism, etc., to ensure that the link can stably transmit Beidou positioning data in various environments.

[0073] Taking a specific scenario as an example, the Beidou positioning platform system may build 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 delays and ensure data security. At the same time, the Beidou positioning platform system will also configure an automatic recovery mechanism for the link so that it can quickly reconnect and continue to transmit data when communication is interrupted.

[0074] Through such steps, the Beidou positioning platform system can ensure that data transmission between vehicle-mounted Beidou positioning nodes is both efficient and reliable, thereby supporting the realization of key functions such as vehicle positioning, navigation and monitoring.

[0075] In a possible implementation, the method further includes: Obtain 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.

[0076] 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 performing positioning performance detection on the Beidou positioning monitoring link based on a preset evaluation phase.

[0077] In the vehicle-mounted positioning system, the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node will perform positioning performance tests on the Beidou positioning monitoring link between them regularly or under specific conditions. These tests are performed during a preset evaluation phase to ensure that the performance of the link is evaluated under similar environments and conditions.

[0078] After completing the performance test, these vehicle-mounted Beidou positioning nodes will generate positioning performance information about each Beidou positioning monitoring link. This information may include data on the link's signal strength, positioning accuracy, response time, stability and other aspects.

[0079] The BeiDou positioning platform system can then 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 through 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.

[0080] For example, suppose the first vehicle-mounted BeiDou positioning node performs a performance test on all BeiDou positioning monitoring links between it and the second vehicle-mounted BeiDou positioning node at 3 a.m. (the preset evaluation phase, when traffic is low and signal interference is less). After the test 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.

[0081] After receiving this information, the Beidou positioning platform system will store, analyze and process it in order to evaluate and optimize the performance of the Beidou positioning monitoring link in the future. 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 time, and take corresponding measures to ensure the stability and accuracy of the vehicle positioning system.

[0082] In a possible implementation manner, the candidate Beidou positioning monitoring link is any Beidou positioning monitoring link between the first vehicle-mounted Beidou positioning node and the second vehicle-mounted Beidou positioning node, and the process in which the first vehicle-mounted Beidou positioning node performs positioning performance detection on the candidate Beidou positioning monitoring link includes: A positioning performance detection instance is sent to the second vehicle-mounted Beidou positioning node by using the positioning channel corresponding to the candidate Beidou positioning monitoring link.

[0083] Based on the feedback status data of the positioning performance detection instance, the positioning performance information of the candidate Beidou positioning monitoring link is determined.

[0084] In this embodiment, when the Beidou positioning platform system determines that the positioning performance test is to be performed, the first vehicle-mounted Beidou positioning node is instructed to start the test process. The first vehicle-mounted Beidou positioning node selects a candidate Beidou positioning monitoring link, which is one of the many links between it and the second vehicle-mounted Beidou positioning node.

[0085] In order to detect the performance of this Beidou positioning monitoring link, the first vehicle-mounted Beidou positioning node will use the positioning channel corresponding to the link to send a positioning performance detection instance to the second vehicle-mounted Beidou positioning node. The detection instance may include a series of test signals, timestamps, and other parameters used to evaluate link performance.

[0086] For example, assuming that the first vehicle-mounted Beidou positioning node selects a candidate Beidou positioning monitoring link that communicates through the 4G network, it will send a detection instance containing a test signal and a timestamp to the second vehicle-mounted Beidou positioning node through the 4G positioning channel of this Beidou positioning monitoring link.

[0087] After receiving the positioning performance test 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, and error range.

[0088] 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 timestamps of sending and receiving, the transmission delay of the signal can be calculated; by analyzing the signal reception strength, the communication quality of the link can be evaluated; and by the error range, the accuracy of positioning can be judged.

[0089] Assume 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 this data, the first vehicle-mounted Beidou positioning node will conduct a comprehensive analysis and conclude that the positioning performance information of the candidate Beidou positioning monitoring link is "general communication quality, there is a certain positioning error, and further optimization is needed."

[0090] Through such steps, the Beidou positioning platform system can perform 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.

[0091] In a possible implementation, the positioning performance information of the candidate Beidou positioning monitoring link includes a positioning response time. The first vehicle-mounted Beidou positioning node comes from a node group of a first module in the vehicle-mounted positioning communication system, and the second vehicle-mounted Beidou positioning node comes from a node group of a second module in the vehicle-mounted positioning communication system, and the node group of the first module is also configured with a first relay device, and the node group of the second module is also configured with a second relay device.

[0092] The determining, based on the feedback status data of the positioning performance detection instance, the positioning performance information of the candidate Beidou positioning monitoring link comprises: Obtain the positioning performance detection instance transmitted by the first relay device. The positioning performance detection instance of the first relay device is continued to be transmitted by the first relay device after obtaining the positioning performance detection instance transmitted by the second relay device. The positioning performance detection instance of the second relay device is continued to be transmitted by the second relay device after obtaining 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 continued to be transmitted by the second vehicle-mounted Beidou positioning node after obtaining the positioning performance detection instance transmitted by the first vehicle-mounted Beidou positioning node.

[0093] The positioning response time is determined 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.

[0094] In this embodiment, in a vehicle-mounted positioning communication system, there are two main modules: a first module and a second module. Each module has a group of nodes, wherein the first vehicle-mounted Beidou positioning node belongs to the node group of the first module, and the second vehicle-mounted Beidou positioning node belongs to the node group of the second module. In order to enhance the signal transmission capability and expand the coverage range, the first module is also configured with a first relay device, and the second module is configured with a second relay device.

[0095] The first vehicle-mounted Beidou positioning node will first generate a positioning performance detection instance and send 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 will immediately pass it to the second relay device in the same module. After receiving the detection instance, the second relay device will continue to pass it to the first relay device of the first module. The first relay device will eventually transmit this detection instance back to the first vehicle-mounted Beidou positioning node. This series of transmission processes not only tests the direct communication performance between vehicle-mounted Beidou positioning nodes, but also tests the performance of signal transmission through relay devices.

[0096] When the first vehicle-mounted Beidou positioning node sends out a positioning performance detection instance, the sending time (time domain) is recorded. When the first vehicle-mounted Beidou positioning node finally receives 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 a detection instance at 10:00:00 and receives the detection instance transmitted back through the relay device at 10:00:05, then the positioning response time of this link is 5 seconds.

[0097] In this way, the BeiDou positioning platform system can accurately measure the positioning response time of the candidate BeiDou positioning monitoring links to evaluate their performance, which is crucial for the optimization and troubleshooting of the vehicle-mounted positioning communication system.

[0098] Alternatively, in another possible implementation, the 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: Obtain a 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.

[0099] The positioning response time is determined based on a time domain interval parameter between a time domain when the first vehicle-mounted Beidou positioning node obtains the positioning feedback signal and a time domain when the first vehicle-mounted Beidou positioning node sends the positioning performance detection instance.

[0100] In the vehicle-mounted positioning system of this embodiment, 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 feedback from the second vehicle-mounted Beidou positioning node. The feedback is about the processing result of the detection instance, which we call a positioning feedback signal.

[0101] Specifically, after receiving the positioning performance test instance, the second vehicle-mounted Beidou positioning node will process it according to the preset process, such as parsing the data in the test instance, executing relevant positioning algorithms, and generating a positioning feedback signal based on the processing results. The signal contains important information about the performance of the candidate Beidou positioning monitoring link, such as signal reception quality, processing time, etc.

[0102] After completing the generation of 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 the signal back to the first vehicle-mounted Beidou positioning node. The transmission process is completed through a wireless communication network, which can be 4G, 5G or other dedicated wireless communication protocols.

[0103] The Beidou positioning platform system is responsible for monitoring and receiving these positioning feedback signals during this process. After the Beidou positioning platform system obtains these signals from the first vehicle-mounted Beidou positioning node, it will perform subsequent analysis and processing.

[0104] Positioning response time is one of the important indicators for evaluating the performance of the Beidou positioning monitoring link. In order 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, suppose that the first vehicle-mounted Beidou positioning node sends a positioning performance detection instance at 9:00 a.m., which is received and processed by the second vehicle-mounted Beidou positioning node after being transmitted through the candidate Beidou positioning monitoring link. 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 a.m.

[0105] When the first vehicle-mounted Beidou positioning node receives the positioning feedback signal at 9:02:30, it sends the receiving time and the previously recorded sending time to the Beidou positioning platform system. After receiving this data, the Beidou positioning platform system calculates the positioning response time, which is the time difference between the receiving time and the sending time. In this example, the positioning response time is 2 minutes and 30 seconds.

[0106] The Beidou positioning platform system can conduct a comprehensive evaluation of the performance of candidate Beidou positioning monitoring links based on this positioning response time and other relevant performance data. The evaluation results can help system administrators understand the actual performance status of the link in order to make necessary optimizations and adjustments.

[0107] Alternatively, in another possible implementation, the 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: Obtain a 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, wherein the positioning feedback signal contains a time domain when the second vehicle-mounted Beidou positioning node obtains the positioning performance detection instance.

[0108] The positioning response time is determined based on the time domain interval parameter between the time domain when the second 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.

[0109] In this embodiment, during the operation of the vehicle-mounted positioning system, the first vehicle-mounted Beidou positioning node will send 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, which not only contains information about the link performance, but also specifically marks the exact 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 to calculate the positioning response time later.

[0110] The second vehicle-mounted Beidou positioning node will use the positioning channel corresponding to the candidate Beidou positioning monitoring link to transmit the positioning feedback signal with a timestamp back to the first vehicle-mounted Beidou positioning node. The Beidou positioning platform system is responsible for obtaining the feedback signal and its time domain information from the first vehicle-mounted Beidou positioning node.

[0111] Once the BeiDou positioning platform system obtains the positioning feedback signal and its time domain information, it can start to calculate the positioning response time. First, the BeiDou positioning platform system can check the original time domain of the first vehicle-mounted BeiDou positioning node sending the positioning performance test instance. This time is recorded by the first vehicle-mounted BeiDou positioning node when sending the test instance and then passed to the BeiDou positioning platform system.

[0112] Next, the Beidou positioning platform system can compare the time domain of the positioning performance detection instance obtained by the second vehicle-mounted Beidou positioning node with the time domain of the detection instance sent by the first vehicle-mounted Beidou positioning node. By calculating the time difference between the two time domains, the Beidou positioning platform system can obtain the positioning response time.

[0113] Let's take an example to illustrate this process: if the first vehicle-mounted Beidou positioning node sends a positioning performance test instance at 14:00:00, and this time is accurately recorded; then the second vehicle-mounted Beidou positioning node receives this test 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 the positioning response time as 5 seconds, that is, the time interval from sending detection to receiving detection.

[0114] This positioning response time is one of the important indicators for evaluating the performance of candidate Beidou positioning monitoring links. It 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 promptly discover problems in the link and take corresponding measures to optimize and improve it.
