Description

Technical Field

[0001] This invention relates to the field of intelligent transportation and vehicle-to-everything (V2X) communication technology, and in particular to a drone-deployable recyclable WiFi Aware traffic beacon system and method. Background Technology

[0002] With the development of intelligent transportation systems and vehicle-to-everything (V2X) technology, the demand for real-time perception and dynamic dissemination of road traffic information is constantly increasing. Traditional traffic guidance methods mainly rely on fixed road information signs, roadside units, or cloud navigation platforms for information dissemination, but they generally suffer from problems such as long deployment cycles, fixed coverage areas, and delayed responses to sudden traffic events, making it difficult to meet the needs for rapid and dynamic guidance in scenarios such as accidents, congestion, or temporary traffic control.

[0003] On the other hand, existing vehicle-to-everything (V2X) communication methods, such as cellular networks or Bluetooth broadcasting, are easily affected by signal blockage or latency in complex road environments, and it is difficult to achieve fine-grained zone guidance based on road spatial location. At the same time, fixed roadside communication equipment has high construction costs and suffers from low resource utilization in temporary or short-term traffic incident scenarios.

[0004] In addition, existing temporary traffic management solutions mostly rely on manual deployment of warning devices or mobile law enforcement vehicles for on-site guidance, which has shortcomings such as low deployment efficiency, discontinuous coverage, and inconvenience in withdrawal. In particular, it is difficult to form continuous and accurate guidance information coverage in a timely manner in highways or large-scale congestion scenarios.

[0005] Therefore, how to provide a traffic information dissemination mechanism that can be quickly deployed, delivered on demand, dynamically coordinated, and retrievable, so as to achieve rapid response and continuous spatial guidance for sudden traffic incidents, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

When the current state is detected to meet the preset deployment conditions, the drone is controlled to release the corresponding traffic beacon box. When congestion spreads, delivery anomalies occur, or some traffic beacon boxes lose contact in the target area, the subsequent delivery points are adjusted or additional traffic beacon delivery tasks are added.

[0010] As a preferred embodiment of the drone-deployable reusable WiFi Aware traffic beacon system described in this invention, the system performs status detection and device activation after the traffic beacon box lands, and establishes a corresponding communication service status, including: Acquire acceleration data, attitude data, and position change data during the descent of the traffic beacon box, and perform a landing stability determination based on the acceleration data, attitude data, and position change data; Once the traffic beacon box is determined to have landed stably, the device self-test process is initiated, and power detection, positioning module initialization, communication module initialization, and service configuration loading are executed sequentially. Obtain current location information and status information of nearby traffic beacon boxes, establish corresponding traffic beacon collaboration relationships, and generate communication service status; Based on the health status, location status, and coverage of nearby traffic beacons, adjust the broadcast role, broadcast frequency, and service priority of the current traffic beacon. When a location anomaly, hardware anomaly, or communication anomaly is detected, the control traffic beacon box switches its current broadcast service mode to a degraded service state.

[0011] As a preferred embodiment of the drone-deployable reusable WiFi Aware traffic beacon system described in this invention, the system includes: determining a target traffic guidance service based on the current location of the traffic beacon box and a preset service configuration, and executing the traffic guidance service deployment via WiFi Aware, including: The system obtains the current location of the traffic beacon box, road direction information, and preset service configuration. The preset service configuration includes at least the geofence range, target road direction, traffic guidance type, service priority, and broadcast parameters. Based on the positional relationship between the current location of the traffic beacon box and the geofence area, as well as the matching relationship between the current road direction and the target road direction, multiple candidate traffic guidance services are filtered, and the corresponding target traffic guidance service is determined. When multiple candidate traffic guidance services meet the matching conditions at the same time, the current target traffic guidance service is determined based on the traffic event level, the distance between the current location and the target event area, the road congestion status, and the service priority. Based on the target traffic guidance service, corresponding structured traffic guidance information is generated, and the corresponding traffic guidance service is periodically broadcast via WiFi Aware in publisher mode; During the traffic guidance service dissemination process, the traffic beacon box receives service reception and subscription status information from the vehicle subscription terminal, and dynamically adjusts the broadcast frequency, broadcast range, and broadcast content based on the feedback results; When there is service coverage overlap between multiple traffic beacon boxes, each traffic beacon box performs collaborative state interaction and dynamically adjusts its corresponding traffic guidance service role according to service priority and coverage area; When a change in the location of a traffic incident is detected, the congestion area expands, or a nearby traffic beacon box loses contact, the traffic guidance service content corresponding to the current traffic beacon box is switched, and the corresponding broadcast parameters are updated.

Perform integrity and validity checks on the received traffic guidance information, and generate corresponding traffic guidance results based on the check results; When a vehicle moves to the next traffic guidance area, the corresponding next traffic guidance service is automatically discovered based on the next target traffic sign icon in the current traffic guidance information, and a continuous subscription switch is performed; When multiple traffic guidance services are detected to be active simultaneously, the current subscription priority is adjusted based on the traffic incident level, the vehicle's current location, and the vehicle's travel destination, and the corresponding traffic guidance service is switched.

[0013] As a preferred embodiment of the drone-deployable recyclable WiFi Aware traffic beacon system described in this invention, the system includes: performing status maintenance and lifecycle management during the operation of the traffic beacon box service, and controlling the traffic beacon box to enter a await-recycling state when recycling conditions are met to complete device recycling, including: Based on the ongoing status of traffic incidents, the number of vehicle subscribers, the level of broadcast activity, and the remaining battery power of the equipment, the current operating status of the traffic communication beacon box is dynamically evaluated, and the broadcast frequency, broadcast content, and service operation mode are adjusted according to the evaluation results. When the remaining battery power of the device is detected to be lower than the first preset threshold, the traffic beacon box is controlled to reduce the broadcast frequency and turn off non-critical traffic guidance services, while only retaining the core early warning broadcast service. When the remaining battery power of the device is detected to be lower than the second preset threshold or a recycling instruction is received, the traffic beacon box is controlled to stop the normal traffic guidance service and switch to a low-power waiting-for-recycling state. In the low-power waiting-to-recovery state, the traffic beacon box periodically sends out equipment positioning tags, short-range positioning signals or visual recognition tags for drones or ground recovery terminals to perform positioning searches; The drone or ground recovery terminal generates a corresponding recovery path based on the current location, positioning signal strength and historical operation trajectory fed back by the traffic beacon box, and performs the recovery of the target traffic beacon box; Once the traffic beacon box is detected as having been recycled, the corresponding device lifecycle status is updated, and the traffic beacon box is added back to the resource pool of devices to be deployed.

[0014] Secondly, embodiments of the present invention provide a method for deploying and recyclable WiFi Aware traffic beacons from drones, comprising: Acquire traffic incident information and road operation status information to generate traffic beacon deployment tasks that include target deployment areas, traffic service types, and recovery strategies; Control the drone to fly to the target area according to the delivery mission, and perform the fixed-point delivery of traffic beacon boxes; After the traffic beacon box is deployed, it performs status detection and device activation, and establishes the corresponding communication service status. The traffic beacon box determines the target traffic service content based on the current location and preset service configuration, and performs traffic service publishing through WiFiAware; After the vehicle-mounted subscription terminal discovers and subscribes to the traffic service, it receives the corresponding traffic guidance information and outputs the traffic guidance result. Traffic beacon boxes perform status maintenance and lifecycle management during service operation, and enter the waiting-to-be-recycled state when recycling conditions are met to complete equipment recycling.

[0015] Thirdly, embodiments of the present invention provide a computer device, including a memory and a processor, wherein the memory stores a computer program, wherein: when the computer program instructions are executed by the processor, they implement the steps of a drone-deployable reusable WiFi Aware traffic beacon system as described in the first aspect of the present invention.

Attached Figure Description

[0018] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 This is a schematic diagram of the system structure of the present invention; Figure 2 This is a flowchart of the method of the present invention. Detailed Implementation

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0023] Reference Figures 1-2This is the first embodiment of the present invention, which provides a drone-deployable recyclable WiFi Aware traffic beacon system. The system consists of a task scheduling module, a drone deployment module, a landing activation module, a service publishing module, a terminal guidance module, and a lifecycle management module.

[0024] Specifically, the task scheduling module is used to acquire traffic incident information and road operation status information, and generate traffic beacon deployment tasks that include target deployment areas, traffic service types and recovery strategies.

[0025] Furthermore, it acquires traffic incident information, road operation status information, and road topology information; The target traffic control area and corresponding traffic service type are determined based on the event level, congestion range, traffic flow changes and road conditions. A set of target deployment points is generated based on the target traffic control area, the coverage area of ​​traffic signs, and the distribution of road nodes, and a continuous traffic guidance relationship is established between traffic sign boxes; A corresponding recycling strategy is generated by combining equipment status information, task duration, and recycling conditions, and a traffic beacon deployment task is generated based on the target deployment point set, traffic service type, and recycling strategy.

[0026] For example, in this embodiment, when a traffic accident occurs on a highway, the task scheduling module first receives traffic event information uploaded from the accident alarm terminal, video surveillance system, navigation platform, and vehicle network terminal. This traffic event information includes at least the accident location, accident type, number of affected lanes, location of the tail end of the congestion, and real-time vehicle speed information. Simultaneously, the task scheduling module obtains corresponding road operating status information and road topology information. The road operating status information includes at least the average road speed, vehicle density, traffic flow growth rate, and diversion exit traffic status; the road topology information includes at least the road direction, ramp distribution, emergency lane location, and key traffic node locations.

[0027] Subsequently, the task scheduling module determines the target traffic control area based on the accident level, congestion range, traffic flow changes, and road conditions. For example, when it is detected that the tail of the congestion continues to expand upstream, the target traffic control area is dynamically expanded, and the area upstream of the accident point, the tail of the congestion area, the emergency lane entrance area, and the diversion exit area are divided into different traffic guidance areas.

[0028] After determining the target traffic control area, the task scheduling module further determines the corresponding traffic service type based on the traffic management objectives of different areas. Specifically, traffic signal boxes located upstream of the accident site can be configured for accident warning services, traffic signal boxes located at the tail end of congestion areas can be configured for deceleration and early lane changing services, traffic signal boxes located at the entrance of emergency lanes can be configured for emergency yielding services, and traffic signal boxes located at diversion exit areas can be configured for detour and diversion services.

[0029] Subsequently, the task scheduling module generates a set of target deployment points based on the length of the target traffic control area, the coverage range of traffic beacons, and the distribution of road nodes. Specifically, the task scheduling module can segment the target traffic control area according to the effective broadcast coverage distance of the traffic beacons, and prioritize key road nodes such as upstream of accident points, congestion tails, road merging points, and ramp exits as target deployment points, so that multiple traffic beacon boxes form a continuous traffic guidance coverage link.

[0030] Furthermore, to avoid broadcast overlap or guidance gaps between multiple traffic guidance beacons, the task scheduling module can also establish continuous traffic guidance relationships between traffic guidance beacons. For example, when a previous traffic guidance beacon issues a traffic guidance service, it can simultaneously carry the service identification information corresponding to the next traffic guidance beacon, enabling the vehicle terminal to automatically switch to the next traffic guidance service while the vehicle is moving, thereby forming a continuous traffic guidance chain.

[0031] In addition, the task scheduling module can generate corresponding recovery strategies by combining the current remaining battery power of the equipment, the online status of the equipment, the expected duration of the task, and the recovery conditions. For example, when the expected duration of the task is long, traffic beacon boxes with higher remaining battery power are given priority; when the target area is close to the drone's cruise path, the automatic drone recovery mode is given priority; and when the target area is in a complex terrain area, a ground-based manual recovery strategy is generated.

[0032] Specifically, the drone delivery module is used to control the drone to fly to the target area according to the traffic beacon delivery task, and to perform the fixed-point delivery of traffic beacon boxes.

[0033] Furthermore, the target deployment point, deployment order, and flight constraints corresponding to the traffic beacon deployment task are obtained; Based on the target delivery point location, road traffic conditions, environmental conditions, and the remaining payload information of the UAV, a corresponding flight path is generated, and the UAV is controlled to fly to the target area according to the flight path; During flight, the drone's flight altitude, ambient wind speed, positional deviation, and equipment status are monitored in real time, and the flight attitude and delivery path are adjusted based on the monitoring results. When the current state is detected to meet the preset deployment conditions, the drone is controlled to release the corresponding traffic beacon box. When congestion spreads, delivery anomalies occur, or some traffic beacon boxes lose contact in the target area, the subsequent delivery points are adjusted or additional traffic beacon delivery tasks are added.

[0034] It should be noted that, in this embodiment, after the task scheduling module generates the traffic beacon delivery task, it sends the target delivery point, delivery order, and flight constraints to the UAV delivery module. The flight constraints include at least no-fly zones, maximum permissible flight altitude, minimum safe flight altitude, maximum lateral deviation, and minimum remaining battery power for return.

[0035] The drone delivery module first acquires the target delivery point location, road traffic conditions, environmental conditions, and the drone's remaining payload information, and then generates a corresponding flight path based on this information. Specifically, the drone delivery module can construct a comprehensive flight cost function: ; in, The overall cost of the current flight path, This represents the flight distance between the drone's current location and the target delivery point. This indicates the current environmental wind speed influencing factor. The obstacle risk coefficient corresponding to the flight path. The remaining battery power of the drone. , , , These are the corresponding weighting coefficients.

[0036] The drone deployment module selects the corresponding flight path based on the principle of minimizing overall flight cost and controls the drone to fly to the target area according to the flight path.

[0037] During flight, the drone continuously monitors its altitude, ambient wind speed, positional deviation, and equipment status, and adjusts its flight attitude and delivery path in real time based on the monitoring results. For example, when an increase in crosswind speed is detected, the drone reduces lateral drift by adjusting its yaw angle and flight speed; when a temporary obstacle area is detected ahead, the drone dynamically corrects its subsequent flight path.

[0038] Furthermore, to improve the accuracy of traffic beacon box delivery, the drone delivery module can also build a delivery deviation assessment model: ; in, This is due to the current delivery deviation. The current real-time deployment coordinates of the drone. The coordinates of the target delivery point.

[0039] When the delivery deviation is less than the preset deviation threshold, and the flight altitude, wind speed, and equipment status meet the preset delivery conditions, the drone is controlled to release the corresponding traffic beacon box.

[0040] The drone can use an electromagnetic mounting mechanism, a mechanical locking mechanism, or a parachute release mechanism to release the traffic beacon box. After release, the traffic beacon box can reduce the impact upon landing through buffered wing surfaces, parachute components, or elastic cushioning structures, thereby increasing the probability of a stable landing.

[0041] In addition, the drone delivery module can dynamically adjust subsequent delivery tasks based on changes in traffic conditions. For example, when it detects that the tail of the congestion is continuously moving backward, it dynamically adds new target delivery points; when it detects that some traffic beacon boxes are out of contact or have failed to be delivered, it automatically replans the subsequent delivery sequence and adds new traffic beacon delivery tasks.

[0042] Furthermore, to improve continuous traffic guidance coverage, the drone delivery module can dynamically adjust the delivery distance based on the coverage interval between adjacent traffic beacon boxes. For example, when a coverage blind spot is detected between adjacent traffic beacon boxes, the delivery interval between subsequent traffic beacon boxes is automatically reduced; when excessive overlap in broadcast coverage is detected, the subsequent delivery interval is appropriately increased to reduce redundant broadcasts.

[0043] Specifically, the landing activation module is used to perform status detection and device activation after the traffic beacon box has landed, and to establish the corresponding communication service status.

[0044] Furthermore, the acceleration data, attitude data, and position change data of the traffic beacon box during its descent are obtained, and a landing stability determination is performed based on the acceleration data, attitude data, and position change data. Once the traffic beacon box is determined to have landed stably, the device self-test process is initiated, and power detection, positioning module initialization, communication module initialization, and service configuration loading are executed sequentially. Obtain current location information and status information of nearby traffic beacon boxes, establish corresponding traffic beacon collaboration relationships, and generate communication service status; Based on the health status, location status, and coverage of nearby traffic beacons, adjust the broadcast role, broadcast frequency, and service priority of the current traffic beacon. When a location anomaly, hardware anomaly, or communication anomaly is detected, the control traffic beacon box switches its current broadcast service mode to a degraded service state.

[0045] It should be noted that in this embodiment, after the traffic beacon is released from the drone, it enters a descent buffer state, and the internal processor periodically reads the data output by the accelerometer, attitude sensor, and positioning module. The acceleration data reflects the impact changes experienced by the traffic beacon, the attitude data reflects the spatial attitude changes of the traffic beacon, and the position change data reflects the stability of the traffic beacon after landing.

[0046] Furthermore, the landing activation module performs landing stability determination based on acceleration data, attitude data, and position change data. Specifically, when the peak acceleration is detected to exceed a preset impact threshold, a stability window detection mechanism is activated; if, within the preset stability window time, the traffic beacon's attitude change remains below a preset attitude threshold, and its position drift is below a preset displacement threshold, then the traffic beacon is determined to have completed a stable landing.

[0047] After a stable landing is determined, the landing activation module initiates a device self-test process, sequentially executing power detection, positioning module initialization, communication module initialization, and service configuration loading. Specifically, power detection confirms remaining battery power and power supply status; positioning module initialization acquires current GNSS positioning information; communication module initialization activates the WiFiAware communication function; and service configuration loading reads the traffic guidance service template corresponding to the current traffic beacon box.

[0048] If the traffic beacon box fails to locate on the first attempt, the landing activation module can repeatedly perform location initialization within a preset time interval. When the number of repeated location attempts exceeds the threshold, it switches to simplified service mode, only issuing general accident warning information and marking the abnormal location status in the device status information.

[0049] Furthermore, after the communication module completes initialization, the traffic beacon box acquires the status information of neighboring traffic beacon boxes and establishes corresponding traffic beacon cooperation relationships. The status information of neighboring traffic beacon boxes includes at least their location, service type, broadcast strength, broadcast frequency, and device health status.

[0050] Based on the status information of nearby traffic sign boxes, the landing activation module generates the corresponding communication service status. For example, when the current traffic sign box is located upstream of an accident point, an accident warning service status can be generated; when the current traffic sign box is located at the tail end of a congestion area, a deceleration guidance service status can be generated; when a nearby traffic sign box is detected to be out of contact, the module automatically takes over its corresponding traffic guidance service.

[0051] To improve traffic guidance continuity, the landing activation module can dynamically adjust the broadcast role, broadcast frequency, and service priority of the current traffic sign based on its health status, location status, and coverage of neighboring traffic signs. Specifically, when weak broadcast coverage of a neighboring traffic sign is detected, the current traffic sign automatically increases its broadcast frequency and expands its broadcast range; when overlapping broadcast coverage of multiple traffic signs is detected, the broadcast frequency of lower-priority traffic signs is reduced to minimize duplicate broadcasts.

[0052] Furthermore, a collaborative status interaction mechanism can be established between traffic beacon boxes. For example, the current traffic beacon box can periodically broadcast its own service status and remaining battery information, and neighboring traffic beacon boxes can dynamically adjust their service roles based on the received status information, thereby forming a continuous traffic guidance link.

[0053] In addition, when a location anomaly, hardware anomaly, or communication anomaly is detected, the landing activation module controls the traffic sign box to switch its current broadcast service mode to a degraded service state. In the degraded service state, the traffic sign box stops non-critical traffic guidance services, retains only basic accident warning broadcasts and equipment location broadcasts, and reduces the broadcast frequency to extend the remaining operating time of the equipment.

[0054] When a communication module malfunction is detected, the traffic signal box switches to a low-frequency simplified broadcast mode, broadcasting only the device identifier and accident warning information periodically. When the battery level is detected to be below a preset threshold, the high-power collaborative communication function is turned off, and only the core traffic guidance service is retained. When a hardware failure is detected, an abnormal status information is sent to the task scheduling module, and the system enters a pending recovery state.

[0055] Specifically, the service publishing module is used to determine the target traffic guidance service based on the current location of the traffic beacon box and the preset service configuration, and to publish the traffic guidance service through WiFi Aware.

[0056] Furthermore, the current location of the traffic beacon box, road direction information, and preset service configuration are obtained. The preset service configuration includes at least the geofence range, target road direction, traffic guidance type, service priority, and broadcast parameters. Based on the positional relationship between the current location of the traffic beacon box and the geofence area, as well as the matching relationship between the current road direction and the target road direction, multiple candidate traffic guidance services are filtered, and the corresponding target traffic guidance service is determined. When multiple candidate traffic guidance services meet the matching conditions at the same time, the current target traffic guidance service is determined based on the traffic event level, the distance between the current location and the target event area, the road congestion status, and the service priority. Based on the target traffic guidance service, corresponding structured traffic guidance information is generated, and the corresponding traffic guidance service is periodically broadcast via WiFi Aware in publisher mode; During the traffic guidance service dissemination process, the traffic beacon box receives service reception and subscription status information from the vehicle subscription terminal, and dynamically adjusts the broadcast frequency, broadcast range, and broadcast content based on the feedback results; When there is service coverage overlap between multiple traffic beacon boxes, each traffic beacon box performs collaborative state interaction and dynamically adjusts its corresponding traffic guidance service role according to service priority and coverage area; When a change in the location of a traffic incident is detected, the congestion area expands, or a nearby traffic beacon box loses contact, the traffic guidance service content corresponding to the current traffic beacon box is switched, and the corresponding broadcast parameters are updated.

[0057] It should be noted that, in this embodiment, after the traffic beacon box is activated, the service publishing module obtains the current location, road direction information, and preset service configuration of the traffic beacon box. The preset service configuration includes at least the geofence range, target road direction, traffic guidance type, service priority, broadcast frequency, and broadcast power parameters.

[0058] Specifically, the service publishing module first performs candidate traffic guidance service filtering based on the location relationship between the current location and the target geofence. For example, when the traffic beacon is located upstream of an accident site, the accident warning service is prioritized; when the traffic beacon is located at the tail end of a congestion area, the deceleration and early lane change service is prioritized; and when the traffic beacon is located at the entrance area of ​​the emergency lane, the emergency yield service is prioritized.

[0059] Furthermore, the service publishing module also performs direction filtering based on the matching relationship between the current road direction and the target road direction to avoid publishing incorrect traffic guidance information to the wrong lane or non-target lane.

[0060] The service publishing module periodically broadcasts the corresponding traffic guidance service via WiFi Aware in publisher mode. In this embodiment, the broadcast period can be dynamically adjusted according to road traffic conditions. For example, when the road traffic density is high, the broadcast frequency is increased to speed up vehicle detection; when the traffic conditions tend to be stable, the broadcast frequency is reduced to reduce device power consumption.

[0061] During the traffic guidance service deployment process, the traffic beacon box receives service reception and subscription status information from the in-vehicle subscription terminal. For example, the in-vehicle terminal can provide feedback on the current message reception success rate, detection latency, and signal strength. The service deployment module dynamically adjusts the broadcast frequency, broadcast range, and broadcast content based on the feedback results. When a decrease in vehicle detection success rate is detected, the broadcast frequency is increased and the broadcast range is expanded; when a decrease in device battery power is detected, non-critical message fields are compressed and the broadcast frequency is reduced.

[0062] Furthermore, when there is service coverage overlap between multiple traffic beacon boxes, each traffic beacon box performs collaborative state interaction and dynamically adjusts its corresponding traffic guidance service role based on service priority and coverage area. The service publishing module can construct a coverage overlap assessment model: ; in, For broadcast coverage overlap rate, This represents the area of ​​the overlapping coverage area between adjacent traffic beacon boxes. This represents the total broadcast coverage area of ​​the current traffic beacon boxes.

[0063] When the broadcast coverage overlap rate exceeds a preset threshold, low-priority traffic beacon boxes automatically reduce broadcast power or switch to auxiliary broadcast mode; high-priority traffic beacon boxes maintain the full broadcast of traffic guidance services, thereby reducing duplicate broadcasts and channel occupation.

[0064] In addition, when a change in the location of a traffic incident is detected, the congestion area expands, or a nearby traffic beacon box loses contact, the service publishing module dynamically switches the traffic guidance service content corresponding to the current traffic beacon box and updates the corresponding broadcast parameters.

[0065] For example, when the tail of the congestion continues to extend upstream, the traffic signal box that was originally providing a slow-down reminder can automatically switch to an advance lane change service; when a nearby traffic signal box is detected to be out of contact, the current traffic signal box can automatically take over its corresponding traffic guidance service to maintain continuous traffic guidance coverage.

[0066] Specifically, the terminal guidance module is used to control the in-vehicle subscription terminal to discover and subscribe to the traffic guidance service, receive the corresponding traffic guidance information, and output the traffic guidance results.

[0067] Furthermore, based on the vehicle's current location, driving direction, vehicle type, and current road conditions, multiple traffic guidance services are matched and filtered, and a subscription relationship is established for the corresponding target traffic guidance service. After completing the subscription, you will receive structured traffic guidance information sent by the traffic beacon box. The traffic guidance information includes at least the event type, impact distance, suggested lane, target action, speed limit suggestion, diversion exit information and message validity period. Perform integrity and validity checks on the received traffic guidance information, and generate corresponding traffic guidance results based on the check results; When a vehicle moves to the next traffic guidance area, the corresponding next traffic guidance service is automatically discovered based on the next target traffic sign icon in the current traffic guidance information, and a continuous subscription switch is performed; When multiple traffic guidance services are detected to be active simultaneously, the current subscription priority is adjusted based on the traffic incident level, the vehicle's current location, and the vehicle's travel destination, and the corresponding traffic guidance service is switched.

[0068] It should be noted that, in this embodiment, after a vehicle enters the coverage area of ​​a traffic beacon, the terminal guidance module periodically performs WiFi Aware service discovery and obtains the traffic guidance service identifier, service description information, and broadcast strength information published by surrounding traffic beacons.

[0069] Furthermore, the terminal guidance module matches and filters multiple traffic guidance services based on the vehicle's current location, driving direction, vehicle type, and current road conditions. For example, when a vehicle is in the upstream lane of an accident site, the accident warning service is prioritized; when a vehicle is approaching a diversion exit, the detour diversion service is prioritized; and when the vehicle type is a rescue vehicle, the emergency lane guidance service is prioritized.

[0070] The terminal guidance module selects the corresponding target traffic guidance service based on the matching score and establishes a subscription relationship with the corresponding traffic beacon box. After completing the subscription, the terminal guidance module receives structured traffic guidance information sent by the traffic beacon box. This traffic guidance information includes at least the event type, impact distance, suggested lane, target action, speed limit suggestion, diversion exit information, and message validity period.

[0071] Furthermore, the terminal guidance module performs integrity verification and validity checks on the received traffic guidance information. For example, the terminal guidance module can perform message validity checks based on the message signature field, timestamp information, and service number to avoid receiving abnormal or expired traffic guidance information.

[0072] When the credibility of traffic guidance information is lower than a preset threshold, the terminal guidance module rejects the current traffic guidance information; when the credibility meets the requirements, the corresponding traffic guidance result is generated based on the traffic guidance information.

[0073] In addition, when a vehicle moves to the next traffic guidance area, the terminal guidance module automatically discovers the corresponding next traffic guidance service based on the next target traffic sign in the current traffic guidance information, and performs continuous subscription switching, thereby forming a continuous traffic guidance chain.

[0074] The current traffic beacon can carry the next traffic beacon service identifier, estimated switching distance, and target road direction information in the traffic guidance information. The terminal guidance module searches for the next traffic guidance service in advance based on the above information to reduce service switching latency.

[0075] Furthermore, when multiple traffic guidance services are detected to be effective simultaneously, the terminal guidance module dynamically adjusts the current subscription priority based on the traffic event level, the vehicle's current location, and the vehicle's travel destination, and switches the corresponding traffic guidance service.

[0076] For example, when a vehicle approaches an accident area, the priority of the accident warning service is increased; when a vehicle has entered the diversion exit area, the priority of the accident warning service is decreased and the priority of the detour guidance service is increased; when the vehicle's travel destination changes, the corresponding traffic guidance service is dynamically switched.

[0077] Specifically, the lifecycle management module is used to perform status maintenance and lifecycle management during the operation of the traffic beacon box service, and to control the traffic beacon box to enter the waiting-to-be-recycle state to complete the equipment recycling when the recycling conditions are met.

[0078] Furthermore, based on the ongoing status of traffic incidents, the number of vehicle subscribers, the level of broadcast activity, and the remaining battery power of the equipment, the current operating status of the traffic communication beacon box is dynamically evaluated, and the broadcast frequency, broadcast content, and service operation mode are adjusted according to the evaluation results. When the remaining battery power of the device is detected to be lower than the first preset threshold, the traffic beacon box is controlled to reduce the broadcast frequency and turn off non-critical traffic guidance services, while only retaining the core early warning broadcast service. When the remaining battery power of the device is detected to be lower than the second preset threshold or a recycling instruction is received, the traffic beacon box is controlled to stop the normal traffic guidance service and switch to a low-power waiting-for-recycling state. In the low-power waiting-to-recovery state, the traffic beacon box periodically sends out equipment positioning tags, short-range positioning signals or visual recognition tags for drones or ground recovery terminals to perform positioning searches; The drone or ground recovery terminal generates a corresponding recovery path based on the current location, positioning signal strength and historical operation trajectory fed back by the traffic beacon box, and performs the recovery of the target traffic beacon box; Once the traffic beacon box is detected as having been recycled, the corresponding device lifecycle status is updated, and the traffic beacon box is added back to the resource pool of devices to be deployed.

[0079] It should be noted that, in this embodiment, after the traffic beacon box enters the service operation state, the lifecycle management module periodically obtains the traffic event continuity status, the number of vehicle subscriptions, the broadcast activity level, the remaining battery power of the device, the device health status, and the current traffic guidance service status, and dynamically evaluates the current operation status of the traffic beacon box based on the above information.

[0080] Specifically, when a traffic incident is detected to be still in a high-impact state, the number of vehicle subscribers continues to increase, and the broadcast activity level is high, the lifecycle management module controls the traffic beacon box to maintain a high-frequency traffic guidance service broadcast state to improve vehicle detection efficiency and traffic guidance continuity; when the number of vehicle subscribers is detected to be gradually decreasing or the road traffic status is restored, the broadcast frequency is appropriately reduced and the broadcast content of non-critical traffic guidance information is reduced to reduce device power consumption.

[0081] Furthermore, the lifecycle management module can perform tiered service degradation control on traffic sign boxes. For example, when the remaining battery power of the device is detected to be lower than a first preset threshold, the traffic sign box enters a first-level energy-saving state. In the first-level energy-saving state, the broadcast frequency is reduced, and non-critical traffic guidance services such as detour recommendations, extended road prompts, and historical congestion information are turned off, while only core traffic guidance services such as accident warnings, speed reduction reminders, and emergency yielding are retained.

[0082] As the remaining battery power of the device continues to decrease, the lifecycle management module controls the traffic beacon box to enter a level 2 energy-saving state. In the level 2 energy-saving state, only the basic accident warning broadcast function is retained, while the broadcast message length is shortened and cooperative communication with neighboring traffic beacon boxes is stopped to further extend the remaining working time.

[0083] In addition, when the remaining battery power of the device is detected to be lower than the second preset threshold, the traffic event ends, there are no vehicles subscribing for a long time, or a recycling instruction is received, the lifecycle management module controls the traffic beacon box to stop publishing the normal traffic guidance service and switch to a low-power waiting-for-recycling state.

[0084] In the low-power recovery state, the traffic signal box shuts down the high-power communication module and only periodically sends out device location identifiers, short-range location signals or visual recognition identifiers for drones or ground recovery terminals to perform location searches.

[0085] In this embodiment, the traffic beacon box can transmit its current location identifier via low-frequency Beacon broadcast; at the same time, it can improve the accuracy of UAV short-range search through ultra-wideband short-range positioning signals; and in nighttime or low-visibility environments, it can also periodically activate a bright flashing indicator light to improve the success rate of visual recognition.

[0086] Furthermore, the lifecycle management module can dynamically generate equipment recovery priorities based on the current location of the traffic signal beacon box, the road hazard level, the remaining battery power of the device, and the difficulty of equipment recovery. For example, when the traffic signal beacon box is located near the main lane of a highway, the emergency lane, or a bridge area, the recovery priority of the corresponding device is increased to avoid the traffic signal beacon box remaining for a long time and affecting road traffic.

[0087] In this embodiment, after receiving the recovery task, the UAV recovery terminal performs a low-altitude cruise search based on the current location and positioning identifier fed back by the traffic beacon box, and identifies the corresponding traffic beacon box using a visual recognition module. When the target traffic beacon box is detected, the UAV descends to the preset recovery height and completes the equipment recovery through a mechanical clamping mechanism, an electromagnetic adsorption mechanism, or a flexible recovery mechanism.

[0088] When the target area is detected to have a complex obstacle environment, strong wind environment, or when the drone cannot land safely, the life cycle management module automatically switches to the ground manual assisted recovery mode and sends the corresponding location and equipment status information of the target traffic beacon box to the ground recovery terminal.

[0089] Furthermore, after the traffic beacon box is recycled, the lifecycle management module updates the corresponding device lifecycle status and records the device's cumulative deployment count, cumulative service duration, battery health status, abnormal operation records, and recycling completion time.

[0090] Subsequently, the lifecycle management module performs a status reset and resource registration for the traffic beacon boxes that have been recovered, and adds them back to the resource pool of devices to be deployed for repeated scheduling in subsequent traffic events.

[0091] This embodiment also provides a method for drone-deployable reusable WiFi Aware traffic beacons, including: Acquire traffic incident information and road operation status information to generate traffic beacon deployment tasks that include target deployment areas, traffic service types, and recovery strategies; Control the drone to fly to the target area according to the delivery mission, and perform the fixed-point delivery of traffic beacon boxes; After the traffic beacon box is deployed, it performs status detection and device activation, and establishes the corresponding communication service status. The traffic beacon box determines the target traffic service content based on the current location and preset service configuration, and performs traffic service publishing through WiFiAware; After the vehicle-mounted subscription terminal discovers and subscribes to the traffic service, it receives the corresponding traffic guidance information and outputs the traffic guidance result. Traffic beacon boxes perform status maintenance and lifecycle management during service operation, and enter the waiting-to-be-recycled state when recycling conditions are met to complete equipment recycling.
