These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0016] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0017] In order to solve the above problems, the embodiments provided in this application are intended to solve the problem of data transmission priority division and communication link selection in the intelligent traffic management system. The method obtains traffic monitoring data through a traffic monitoring device cluster and transmits it to an industrial switch to form a traffic monitoring data set. The industrial switch evaluates the urgency, decision value and data reliability of the traffic monitoring data according to a preset transmission priority determination model, and calculates the transmission priority characteristic value based on this, and then determines the transmission priority. The industrial switch obtains the communication link status between the intelligent traffic management cloud platform and filters out the available communication link set based on the link status characteristic value. Then, according to the transmission priority of the traffic monitoring data and the state characteristic value of the available communication link, the optimal communication link is allocated for data transmission. In addition, for data that cannot be allocated to the communication link in time, a waiting transmission state is set, and its transmission priority is increased when there is an idle link. Through the technical solution provided by the above embodiment, it is possible to realize the efficient and orderly transmission of a large amount of traffic monitoring data in the intelligent traffic management system, and improve the timeliness and accuracy of data processing. In addition, through the automated transmission priority determination mechanism, it is ensured that urgent and important traffic monitoring data can be processed first, thereby improving the response speed of traffic events. In addition, through real-time monitoring of link status and selection of the optimal link, data transmission delay and packet loss rate are effectively reduced, and the utilization rate of communication links and the stability of the entire system are improved. The unallocated data processing mechanism ensures that all data can be effectively transmitted in the end, reducing data waiting time and improving the overall efficiency of the system.

[0018] Figure 1 FIG. 1 is a flow chart of an intelligent traffic data transmission method based on an industrial switch according to an exemplary embodiment of the present application. Figure 1 As shown, the intelligent traffic data transmission method based on the industrial switch provided in this embodiment includes: S101. Acquire traffic monitoring data through each traffic monitoring device in a traffic monitoring device cluster, and transmit the traffic monitoring data to an industrial switch.

[0019] The method provided in this embodiment can be applied to an intelligent traffic management system, which includes a traffic monitoring device cluster, an industrial switch, and an intelligent traffic management cloud platform. Each traffic monitoring device in the traffic monitoring device cluster is respectively connected to the industrial switch in communication, and the industrial switch is connected to the intelligent traffic management cloud platform in communication. Optionally, the above-mentioned traffic monitoring equipment can be a plurality of deployed traffic monitoring devices, such as cameras, sensors, etc., which are responsible for capturing information such as traffic flow, vehicle speed, and accident scene in real time. Each traffic monitoring device establishes a communication connection with the industrial switch through a network interface, and sends the collected traffic monitoring data to the industrial switch in the form of a data packet. The data packet includes but is not limited to information such as timestamp, geographic location, and data type. In addition, the above-mentioned traffic monitoring data can also be data that is manually judged and annotated based on the data obtained by the camera or sensor.

[0020] S102: The industrial switch determines the transmission priority of each traffic monitoring data in the traffic monitoring data set by using a preset transmission priority determination model.

[0021] In this step, after receiving the data, the industrial switch first parses the data packet to extract characteristic information such as urgency, decision value, and data reliability. The urgency can be determined based on the type of traffic event (such as traffic accidents, congestion, special vehicle traffic, etc.) and the severity of the event (such as whether it involves casualties, whether it causes road congestion, etc.). The decision value can be determined based on the degree of support for traffic management and scheduling decisions, such as whether the data can help predict the changing trend of traffic flow. In addition, data reliability can be determined based on factors such as the credibility of the data source, completeness, and whether there are outliers.

[0022] In one possible implementation, an industrial switch obtains data feature information of traffic monitoring data in a traffic monitoring data set, wherein the data feature information includes an urgency field, a decision value field, and a data reliability field, and the traffic monitoring data is traffic monitoring data obtained by any traffic monitoring device in a traffic monitoring device cluster.

[0023] It is worth noting that the above-mentioned urgency field reflects the urgency of the traffic incident and the degree to which it needs to be handled immediately. Among them, different types of traffic incidents have different urgency levels. For example, a traffic accident may be more urgent than a simple traffic jam. The larger the scope of the incident, the higher the urgency. For example, an accident with multi-lane blockade is more urgent than an accident with a single lane. If the incident involves personal injury or life-threatening, the urgency is higher. Long-term traffic disruptions will also increase the urgency. Incidents occurring during peak hours may be more urgent than those during non-peak hours. It may be possible to use a scoring system to assign a certain score to each of the above items, set different weights for different event types according to actual conditions, and then calculate the total score and map it to an urgency level. In addition, it can also be based on manual annotation of the urgency field.

[0024] The decision value field above reflects the extent to which the data helps traffic managers make decisions. This includes whether the data can help predict future traffic conditions, whether it helps improve traffic efficiency, whether it can help emergency response teams arrive at the scene faster, and whether it has long-term value for urban traffic planning. For each item, a scoring system can also be used. Give each item different weights to reflect their importance to the decision, and add up the weighted scores to get the total score of the decision value. In addition, the urgency field can also be manually labeled.

[0025] The above data reliability fields reflect the accuracy and credibility of the data. Specifically, the reliability of the data source can be considered. For example, data from official sensors are usually more reliable than data from third parties. You can also consider whether the data is complete, consistent with other related data, and whether the data contains outliers. You can use a scoring system to score each item, give different weights to each item according to the actual situation, calculate the total score and map it to the reliability level. In addition, it can also be based on manual annotation of the urgency field.

[0026] Assume in this example that the following weighting and scoring system may be used: Urgency: Event type (weight 0.4): 1-5 points Impact range (weight 0.3): 1-5 points Personnel safety (weight 0.2): 1-5 points Traffic disruption (weight 0.1): 1-5 points Decision value: Event predictability (weight 0.3): 1-5 points Improve traffic mobility (weight 0.3): 1-5 points Auxiliary emergency response (weight 0.2): 1-5 points Support long-term planning (weight 0.2): 1-5 points Data Reliability: Data source (weight 0.3): 1-5 points Data integrity (weight 0.3): 1-5 points Data consistency (weight 0.2): 1-5 points Anomaly detection (weight 0.1): 1-5 points Data freshness (weight 0.1): 1-5 points For a specific data packet, we can score each item through expert evaluation or pre-set rules, and then calculate the weighted average score according to the above weights. For example, for a data packet: Urgency: Event Type: 4 points Impact range: 3 points Personnel safety: 5 points Traffic disruption: 2 points Total score: 0.4×4+0.3×3+0.2×5+0.1×2=3.6 Decision value: Event predictability: 4 points Improved traffic mobility: 3 points Assisted Emergency Response: 5 points Support for long-term planning: 2 points Total score: 0.3×4+0.3×3+0.2×5+0.2×2=3.3 Data Reliability: Data source: 5 points Data integrity: 4 points Data consistency: 5 points Anomaly Detection: 2 points Data freshness: 3 points Total score: 0.3×5+0.3×4+0.2×5+0.1×2+0.1×3=4.1 Furthermore, the industrial switch uses Formula 1 and determines the transmission priority characteristic value corresponding to the traffic monitoring data according to the data characteristic information, where Formula 1 is:

[0027] in, The traffic monitoring data set The transmission priority characteristic value corresponding to the traffic monitoring data, For the The characteristic value corresponding to the urgency field in the traffic monitoring data, For the The feature value corresponding to the decision value field in the traffic monitoring data, For the The characteristic value corresponding to the data reliability field in the traffic monitoring data, is the first weight coefficient, is the second weight coefficient, is the third weight coefficient; The industrial switch determines the transmission priority corresponding to each traffic monitoring data in the traffic monitoring data set according to the transmission priority characteristic value and the preset transmission priority range interval.

[0028] S103: The industrial switch obtains a set of available communication links.

[0029] In this step, the industrial switch obtains a set of communication links to be selected, which is a set of communication links between the industrial switch and the intelligent traffic management cloud platform.

[0030] Optionally, the industrial switch obtains all communication links between it and the intelligent traffic management cloud platform as a set of candidate communication links. For each candidate communication link in the set of candidate communication links, a first link status check instruction may be sent at a first time node, and the instruction includes a sending timestamp. After receiving the instruction, the intelligent traffic management cloud platform records the received timestamp and calculates the first duration (i.e., the time difference between sending and receiving). At a third time node, the intelligent traffic management cloud platform sends a first link status confirmation instruction to the industrial switch, and the instruction includes the timestamp of receiving the first link status check instruction and the first duration. After receiving the confirmation instruction, the industrial switch records the received timestamp and calculates the second duration (i.e., the time difference between sending the confirmation instruction and receiving the confirmation instruction).

[0031] Specifically, at a first time node, the industrial switch sends a first link state verification instruction to a first selected communication link in the set of selected communication links, where the first link state verification instruction includes first time node information corresponding to the first time node, and the first selected communication link is any selected communication link in the set of selected communication links; At the second time node, the intelligent traffic management cloud platform receives the first link status verification instruction, and determines the first duration according to the first time node and the second time node in the first time node information; At the third time node, the intelligent traffic management cloud platform responds to the first link state verification instruction and sends a first link state confirmation instruction to the first selected communication link, where the first link state confirmation instruction includes the third time node information corresponding to the third time node and the first duration; At the fourth time node, the industrial switch receives the first link status check instruction, and determines the second duration according to the third time node and the fourth time node in the third time node information; The industrial switch determines a first link state characteristic value of a first candidate communication link according to the first duration and the second duration, and the first link state characteristic value is negatively correlated with the first duration and the second duration; If the first link state characteristic value is greater than a preset link state characteristic threshold, the first to-be-selected communication link is an available communication link in the set of available communication links.

[0032] In a possible implementation, the industrial switch determines the first link state characteristic value of the first candidate communication link according to the first duration and the second duration, which may include: Industrial switches use Formula 2 and according to the first duration And the second duration Determine a first link state characteristic value , where the above formula 2 is:

[0033] in, is the first preset positive parameter, is the second preset positive parameter, and .

[0034] In the above formula 2, the first duration And the second duration Link state feature value The effect of is negatively correlated, which means that if the first duration And the second duration Smaller, indicating a good link status, the corresponding link status characteristic value The value of is larger. On the contrary, if the first duration And the second duration If it is larger, it means the link status is poor, and the corresponding link status characteristic value In addition, in the above formula 2, the first preset positive parameter can also be dynamically adjusted With the second preset positive parameter , thereby controlling the influence of the transmission time of two different data transmission directions on the link state characteristic value. In addition, since the subsequent communication link is mainly used to transmit traffic monitoring data from the industrial switch to the intelligent traffic management cloud platform, therefore, in Formula 2, , which can better match the communication link suitable for transmitting data from industrial switches to the intelligent traffic management cloud platform, and further improve the transmission efficiency of intelligent traffic data.

[0035] S104: Determine a target communication link for each traffic monitoring data from a set of available communication links according to the transmission priority of each traffic monitoring data in the traffic monitoring data set.

[0036] In this step, the target communication link of each traffic monitoring data can be determined from the available communication link set according to the transmission priority of each traffic monitoring data in the traffic monitoring data set, so as to transmit the corresponding traffic monitoring data to the intelligent traffic management cloud platform through the target communication link.

[0037] Specifically, the traffic monitoring data is first sorted in descending order according to the transmission priority to form a traffic monitoring data sequence. Then, a set of available communication link state characteristic values ​​is generated according to the link state characteristic value of each available communication link in the available communication link set. In addition, an initially empty link allocation list is created. The sorted traffic monitoring data sequence is traversed, and the available communication link with the highest communication link state characteristic value is selected for each data, and the allocation information is added to the link allocation list, and the allocated link is removed from the available communication link set. Then, the target communication link of each traffic monitoring data is determined according to the updated link allocation list.

[0038] In a possible implementation, the above-mentioned determining the target communication link of each traffic monitoring data from the available communication link set according to the transmission priority of each traffic monitoring data in the traffic monitoring data set may include: The industrial switch sorts the traffic monitoring data in the traffic monitoring data set in descending order according to the transmission priority of each traffic monitoring data in the traffic monitoring data set to generate a traffic monitoring data sequence ,in, Traffic monitoring data series The amount of traffic monitoring data in the Industrial switches are grouped according to available communication links The link state characteristic value corresponding to each available communication link in generates a set of available communication link state characteristic values ,in, A collection of available communication links The number of available communication links in A collection of available communication links Middle The link status characteristic value corresponding to the available communication link; the industrial switch generates an initialization link allocation list , initialize the link allocation list is an empty list; Industrial switches traverse traffic monitoring data sequence Each piece of traffic monitoring data , select the available communication link with the highest current communication link status characteristic value from the available communication link set Assigned to traffic monitoring data , to form link allocation information , link allocation information Add to initialization link allocation list , to generate an updated link allocation list , and the available communication links From the available communication links Delete from the list to set the available communication links Make updates; Industrial switches update link allocation list Determine the target communication link corresponding to each traffic monitoring data in the traffic monitoring data set.

[0039] In this embodiment, traffic monitoring data is obtained through each traffic monitoring device in the traffic monitoring device cluster, and the traffic monitoring data is transmitted to the industrial switch to form a traffic monitoring data set. The industrial switch uses a preset transmission priority determination model to determine the transmission priority of each traffic monitoring data in the traffic monitoring data set. Then, the industrial switch obtains a set of available communication links, and determines the target communication link of each traffic monitoring data from the set of available communication links according to the transmission priority of each traffic monitoring data in the traffic monitoring data set, so as to transmit the corresponding traffic monitoring data to the intelligent traffic management cloud platform through the target communication link, thereby dynamically adjusting the transmission priority to ensure that urgent and important traffic monitoring data can be transmitted first, thereby improving the response speed and decision-making efficiency of the intelligent traffic management system. In addition, through the evaluation of the link state characteristic value, the optimal communication link is selected for data transmission, which reduces the probability of data transmission failure and improves the overall stability of data transmission. Moreover, through priority determination and link state evaluation, network resources are reasonably allocated, resource waste is avoided, and the resource utilization rate of the entire intelligent traffic management system is improved.

[0040] Figure 2 FIG. 1 is a flow chart of an intelligent traffic data transmission method based on an industrial switch according to another exemplary embodiment of the present application. Figure 2 As shown, the intelligent traffic data transmission method based on the industrial switch provided in this embodiment includes: S201. Obtain a traffic monitoring data request instruction through the intelligent traffic management cloud platform.

[0041] A traffic monitoring data request instruction is obtained through the intelligent traffic management cloud platform, and the monitoring data request instruction includes device information of each monitoring device in the monitoring device cluster.

[0042] Specifically, by actively sending monitoring data request instructions through the intelligent traffic management cloud platform, the type and scope of data to be collected can be flexibly adjusted according to real-time needs, improving the flexibility and pertinence of data acquisition. The request instruction contains the device information of each monitoring device in the monitoring device cluster, ensuring the accuracy of the data request, reducing the possibility of misoperation, and thus improving the security of data transmission.

[0043] S202. The intelligent traffic management cloud platform broadcasts a traffic monitoring data request instruction to the traffic monitoring device cluster.

[0044] Specifically, by broadcasting request instructions to the monitoring equipment cluster through the intelligent traffic management cloud platform, the working status of the monitoring equipment can be controlled and managed more efficiently, unnecessary data collection can be avoided, and the resource utilization of the monitoring equipment can be optimized. In addition, the broadcast request instruction method avoids the network congestion problem that may occur when sending instructions from a single point, reduces unnecessary network communications, and helps to reduce network load.

[0045] S203: Acquire traffic monitoring data through each traffic monitoring device in the traffic monitoring device cluster, and transmit the traffic monitoring data to the industrial switch.

[0046] Each traffic monitoring device in the traffic monitoring device cluster responds to the traffic monitoring data request instruction, obtains the traffic monitoring data, and transmits the traffic monitoring data to the industrial switch.

[0047] The monitoring data request instruction is actively sent through the intelligent traffic management cloud platform and broadcasted to the monitoring device cluster. Then, each traffic monitoring device in the traffic monitoring device cluster responds to the traffic monitoring data request instruction, obtains the traffic monitoring data and transmits it to the industrial switch. This can not only improve the flexibility and security of data acquisition, but also optimize resource utilization, reduce network load, improve data transmission efficiency, enhance system scalability, improve data quality, and reduce false alarm rate, thereby improving the performance and efficiency of the intelligent traffic management system as a whole.

[0048] S204: The industrial switch determines the transmission priority of each traffic monitoring data in the traffic monitoring data set by using a preset transmission priority determination model.

[0049] In this step, after receiving the data, the industrial switch first parses the data packet to extract characteristic information such as urgency, decision value, and data reliability. The urgency can be determined based on the type of traffic event (such as traffic accidents, congestion, special vehicle traffic, etc.) and the severity of the event (such as whether it involves casualties, whether it causes road congestion, etc.). The decision value can be determined based on the degree of support for traffic management and scheduling decisions, such as whether the data can help predict the changing trend of traffic flow. In addition, data reliability can be determined based on factors such as the credibility of the data source, completeness, and whether there are outliers.

[0050] In one possible implementation, an industrial switch obtains data feature information of traffic monitoring data in a traffic monitoring data set, wherein the data feature information includes an urgency field, a decision value field, and a data reliability field, and the traffic monitoring data is traffic monitoring data obtained by any traffic monitoring device in a traffic monitoring device cluster.

[0051] It is worth noting that the above-mentioned urgency field reflects the urgency of the traffic incident and the degree to which it needs to be handled immediately. Among them, different types of traffic incidents have different urgency levels. For example, a traffic accident may be more urgent than a simple traffic jam. The larger the scope of the incident, the higher the urgency. For example, an accident with multi-lane blockade is more urgent than an accident with a single lane. If the incident involves personal injury or life-threatening, the urgency is higher. Long-term traffic disruptions will also increase the urgency. Incidents occurring during peak hours may be more urgent than those during non-peak hours. It may be possible to use a scoring system to assign a certain score to each of the above items, set different weights for different event types according to actual conditions, and then calculate the total score and map it to an urgency level. In addition, it can also be based on manual annotation of the urgency field.

[0052] The decision value field above reflects the extent to which the data helps traffic managers make decisions. This includes whether the data can help predict future traffic conditions, whether it helps improve traffic efficiency, whether it can help emergency response teams arrive at the scene faster, and whether it has long-term value for urban traffic planning. For each item, a scoring system can also be used. Give each item different weights to reflect their importance to the decision, and add up the weighted scores to get the total score of the decision value. In addition, the urgency field can also be manually labeled.

[0053] The above data reliability fields reflect the accuracy and credibility of the data. Specifically, the reliability of the data source can be considered. For example, data from official sensors are usually more reliable than data from third parties. You can also consider whether the data is complete, consistent with other related data, and whether the data contains outliers. You can use a scoring system to score each item, give different weights to each item according to the actual situation, calculate the total score and map it to the reliability level. In addition, it can also be based on manual annotation of the urgency field.

[0054] Furthermore, the industrial switch uses Formula 1 and determines the transmission priority characteristic value corresponding to the traffic monitoring data according to the data characteristic information, where Formula 1 is:

[0055] in, The traffic monitoring data set The transmission priority characteristic value corresponding to the traffic monitoring data, For the The characteristic value corresponding to the urgency field in the traffic monitoring data, For the The feature value corresponding to the decision value field in the traffic monitoring data, For the The characteristic value corresponding to the data reliability field in the traffic monitoring data, is the first weight coefficient, is the second weight coefficient, is the third weight coefficient; The industrial switch determines the transmission priority corresponding to each traffic monitoring data in the traffic monitoring data set according to the transmission priority characteristic value and the preset transmission priority range interval.

[0056] S205. The industrial switch obtains a set of available communication links.

[0057] In this step, the industrial switch obtains a set of communication links to be selected, which is a set of communication links between the industrial switch and the intelligent traffic management cloud platform.

[0058] Optionally, the industrial switch obtains all communication links between it and the intelligent traffic management cloud platform as a set of candidate communication links. For each candidate communication link in the set of candidate communication links, a first link status check instruction may be sent at a first time node, and the instruction includes a sending timestamp. After receiving the instruction, the intelligent traffic management cloud platform records the received timestamp and calculates the first duration (i.e., the time difference between sending and receiving). At a third time node, the intelligent traffic management cloud platform sends a first link status confirmation instruction to the industrial switch, and the instruction includes the timestamp of receiving the first link status check instruction and the first duration. After receiving the confirmation instruction, the industrial switch records the received timestamp and calculates the second duration (i.e., the time difference between sending the confirmation instruction and receiving the confirmation instruction).

[0059] Specifically, at a first time node, the industrial switch sends a first link state verification instruction to a first selected communication link in the set of selected communication links, where the first link state verification instruction includes first time node information corresponding to the first time node, and the first selected communication link is any selected communication link in the set of selected communication links; At the second time node, the intelligent traffic management cloud platform receives the first link status verification instruction, and determines the first duration according to the first time node and the second time node in the first time node information; At the third time node, the intelligent traffic management cloud platform responds to the first link state verification instruction and sends a first link state confirmation instruction to the first selected communication link, where the first link state confirmation instruction includes the third time node information corresponding to the third time node and the first duration; At the fourth time node, the industrial switch receives the first link status check instruction, and determines the second duration according to the third time node and the fourth time node in the third time node information; The industrial switch determines a first link state characteristic value of a first candidate communication link according to the first duration and the second duration, and the first link state characteristic value is negatively correlated with the first duration and the second duration; If the first link state characteristic value is greater than a preset link state characteristic threshold, the first to-be-selected communication link is an available communication link in the set of available communication links.

[0060] In a possible implementation, the industrial switch determines the first link state characteristic value of the first candidate communication link according to the first duration and the second duration, and may further include: Industrial switches use Formula 3 and according to the first duration And the second duration Determine a first link state characteristic value ; Wherein, the above formula 3 is:

[0061] in, is the first preset positive parameter, is the second preset positive parameter, is the third preset positive parameter, is the preset duration threshold, and .

[0062] It is worth noting that When the communication link is in a state that is unstable due to network congestion, the third preset positive parameter can be set. Link State Characteristic Value Adjust to better reflect the change of link status, where the preset time threshold Calibration can be performed through testing.

[0063] For example, in a specific application scenario, , , through experiments, it was found that when When the communication link becomes unstable, you can select , thus ensuring that in the first period And the second duration When it is small, the link state characteristic value Stable changes, and in the first period And the second duration When the sum reaches a certain threshold, the link status characteristic value The link status starts to decrease rapidly, which better reflects the change of link status.
