[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] Among the related technologies, the method and system for collecting real-time information of road vehicles based on star flash technology involve the field of wireless communication technology, and solve the technical problem that the information collection of road vehicles is not real-time enough. The key points of its technical solution are to collect real-time information of road vehicles through star flash technology to optimize the traffic control system, so as to adjust the traffic signal strategy in real time, reduce the probability of road vehicle congestion, greatly improve the vehicle traffic efficiency at traffic intersections, and, when road congestion occurs, timely guide subsequent vehicles to divert and relieve traffic, reduce the accumulation of congestion and the duration of congestion.

[0028] Among the related technologies, a smart cycling helmet system based on Star Flash technology is disclosed. The system includes multiple smart helmets, a smartphone equipped with Star Flash technology, and a cloud server. Multiple smart helmets and smartphones equipped with Star Flash technology communicate wirelessly via Star Flash technology to transmit voice information, video information, and helmet-collected information. Smartphones equipped with Star Flash technology communicate wirelessly with the cloud server via 5G technology to upload mobile phone positioning information and helmet-collected information to the cloud server. This technical solution is suitable for use when riding a two-wheeled vehicle. Multiple smart helmets can be connected via Star Flash to enable voice calls between multiple riders. Smartphones equipped with Star Flash technology can also make calls to smart helmets via Star Flash. Furthermore, when a smart helmet detects a rider is in danger, an alarm can be sent via the smartphone.

[0029] The above-mentioned technical solutions cannot regulate the driving routes of two-wheeled vehicles on the road, and there will still be illegal problems such as two-wheeled vehicles running red lights or driving in the wrong direction.

[0030] According to an embodiment of the present invention, a method embodiment for vehicle traffic management is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] In this embodiment, a method for vehicle traffic management is provided, which can be used for a first electronic device, such as a short-range communication device. Figure 1 FIG. 1 is a flow chart showing a method for vehicle traffic management according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, the process includes the following steps:

[0032] In step S101 , a first electronic device is set on a roadside. The first electronic device supports multiple access technologies and selects a first access technology from the multiple access technologies.

[0033] In this step, multiple access technologies include but are not limited to the access technology of the Spark Multi-Link Enhanced (MLE) short-range wireless communication system, the access technology of the Spark Low Energy (SLE) short-range wireless communication system, and other access technologies, such as Bluetooth, WiFi, or other future Spark Alliance access technologies.

[0034] The first access technology can be selected from a variety of access technologies based on scenario requirements, such as traffic flow, positioning accuracy, or latency requirements. Specifically, the first electronic device can select the Star Flash MLE access technology on urban traffic arteries with relatively busy traffic, or on roads congested during rush hours in the morning and evening. On non-motorized vehicle lanes with low traffic at night, the first electronic device can select the Star Flash SLE access technology.

[0035] The optimal access technology can be dynamically switched according to different road environments. At the same time, Star Flash MLE is used in high-throughput scenarios, and Star Flash SLE is switched to during low-traffic periods. This can extend device life and optimize resource utilization and energy consumption management.

[0036] In step S102, the first electronic device obtains identification information of vehicles entering the coverage area of the first electronic device based on the first access technology, determines the number and location of the first electronic devices based on the road length and coverage area, and determines whether the vehicles support the first access technology.

[0037] Figure 2 FIG2 shows a schematic diagram of an application scenario of the method for vehicle traffic management according to an embodiment of the present invention. Figure 2 As shown, in this step, the first electronic device 21 is set on the road side. Figure 2 Lane 22 can be a non-motorized vehicle lane or the rightmost lane on a road without a non-motorized vehicle lane. Vehicles traveling on non-motorized vehicle lanes include bicycles, flatbed trucks, tricycles, electric vehicles, and animal-powered vehicles. Electric vehicles, commonly known as "battery vehicles," are electrically powered vehicles and include standard electric bicycles, mopeds, and regular motorcycles.

[0038] The location of the first electronic device can be set based on a street lamp as a reference object. The first electronic device is arranged along the road according to a certain coverage range, for example, Figure 2 As shown, Figure 2 The blue blocks in the figure are all first electronic devices. The coverage range of the first electronic device 1 (21) is a circle formed with the first electronic device 1 (21) as the center. The radius of the circle can be set by setting the signal strength of the first electronic device 1 (21). That is, different coverage ranges can be obtained by setting different signal strengths.

[0039] In this step, the first electronic device set up on the roadside is the master device, and the vehicle traveling on the lane is the slave device. The master device, that is, the first electronic device, can serve as the core of the short-range network connection between the roadside device and the vehicle, responsible for initiating and managing the short-range network connection, and coordinating and controlling the connection process. Specifically, it can scan and search for slave devices within the coverage of the first electronic device, and after obtaining the slave device, establish a connection with the slave device. The master device has functions such as data processing, data forwarding, and data processing. The master device can classify the slave devices entering its coverage based on identification information, and after classification processing, send the processing results to the control center.

[0040] When the slave device, i.e. the vehicle, enters the coverage area of the master device, it establishes a network connection with the master device and transmits and interacts with the data according to the requirements of the master device.

[0041] In step S103, the first electronic device sends the first electronic device identifier, the vehicle identification information, and the time of obtaining the identification information to the control center. Based on the position of the first electronic device corresponding to the first electronic device identifier, the identification information, and the acquisition time, the driving trajectory of the target vehicle corresponding to the identification information is determined. Based on the driving trajectory, it is determined whether the target vehicle has engaged in the wrong direction or a U-turn.

[0042] Figure 3 FIG. 1 shows a schematic diagram of device interaction in a method for vehicle traffic management according to an embodiment of the present invention. Figure 3 As shown, the slave device 301 includes a first vehicle 3011, a second vehicle 3012, a third vehicle 3013, a fourth vehicle 3014, and the like. The master device 302 includes a plurality of first electronic devices, including a first electronic device 1 (21), a first electronic device 2 (22), a first electronic device 3 (23), and a first electronic device 4 (24). The control center 303 includes a slave device management module 3031, a data center 3032, and a server 3033.

[0043] An independent Internet Protocol Address (IP) or a Media Access Control Address (MAC) can be set for each master device. The following uses the MAC address as an example for explanation. Multiple first electronic devices can be set based on a preset road distance, or they can be deployed based on road traffic density. Multiple first electronic devices are connected to the control center together to form a local area network.

[0044] Specifically, the default MAC address can be set to 00:00:00:00:00:00, the MAC address of the control center host can be set to 00:00:00:00:00:01, and the control center can be set to the highest authority. The master device, that is, the first electronic device, can be configured as a second-level authority, and MAC number segments can be allocated to multiple master devices. Since the location and number of first electronic devices are fixed, a portion of the MAC number segments can be allocated to the master device. The slave device has a third-level authority and is allocated a large number of remaining MAC number segments.

[0045] The control center can be set up according to the area. For example, if a street includes multiple main roads, these main roads can be managed by one control center.

[0046] like Figure 2 As shown, assuming that the MAC address of the slave device 26 is 00:00:00:00:11:01, the slave device 26 is driving on the lane, and in the first time period T1, the slave device 26 is within the coverage of the first electronic device 1 (21). The first electronic device 1 (21) records the MAC address of the slave device 26 and sends the identifier of the first electronic device 1 (21), the identification information of the slave device 26 and the first time period T1 to the control center.

[0047] like Figure 2 As shown, in the second time period T2, the slave device 26 is within the coverage of the first electronic device 2 (22), the first electronic device 2 (22) records the MAC address of the slave device 26, and sends the identifier of the first electronic device 2 (22), the identification information of the slave device 26 and the second time period T2 to the control center.

[0048] like Figure 2 As shown, in the third time period T3, the slave device 26 is within the coverage of the first electronic device 3 (23), the first electronic device 3 (23) records the MAC address of the slave device 26, and sends the identifier of the first electronic device 3 (23), the identification information of the slave device 26, and the third time period T3 to the control center. Among them, the first time period T1 is less than the second time period T2, and the second time period T2 is less than the third time period T3.

[0049] Since the positions of the first electronic devices are known and fixed, the driving trajectory of the slave device can be obtained based on the time sequence of the triggering of the first electronic devices. Figure 2 As shown, if the driving direction that complies with road traffic management regulations is, Figure 2From right to left, for the identification information (from device 26), in chronological order, the order of the identifiers of the first electronic device obtained is first electronic device 1 (21) → first electronic device 2 (22) → first electronic device 3 (23). It can be obtained that the driving trajectory of the slave device 26 represented by the identification information is from right to left, and the target vehicle from device 26 does not have the behavior of going against traffic or making an illegal U-turn.

[0050] Otherwise, the target vehicle may have the behavior of going against traffic or making a U-turn from the device 26, and the driver of the target vehicle may be reminded in the form of a text message, or the behavior of going against traffic or making an illegal U-turn may be sent to the relevant traffic management department.

[0051] The method for vehicle traffic management provided in this embodiment obtains the time of identification information of the target vehicle through multiple first electronic devices set at preset positions on the roadside, determines the driving trajectory of the target vehicle, and then judges whether the target vehicle has reversed or turned around. This can achieve large-scale and centralized supervision of vehicle driving regulations, and help improve the safety and orderliness of the entire transportation system.

[0052] In some optional embodiments, the aforementioned method for vehicle traffic management also includes: the first electronic device is also arranged at the intersection, and the memory capacity of the first electronic device arranged at the intersection is greater than the memory capacity of the first electronic device arranged on the roadside; the distance between the first electronic device arranged at the intersection and the stop line of the intersection is greater than the coverage range of the first electronic device arranged at the intersection; the first electronic device arranged at the intersection is synchronized with the traffic light time, and during the period when the intersection is prohibited from passing, if the first electronic device arranged at the intersection obtains the identification information of the vehicle, the first electronic device arranged at the intersection marks the vehicle represented by the identification information; the first electronic device arranged at the intersection sends the marked vehicle to the control center, and determines that the marked vehicle has run a red light.

[0053] Figure 4 FIG. 1 is a schematic diagram showing another application scenario of the method for vehicle traffic management according to an embodiment of the present invention. Figure 4 As shown, in this embodiment, based on Figure 4The red box in the figure represents the first electronic device 402 set at the intersection. The first electronic device set at the intersection can be equivalent to an enhanced first electronic device. Setting the memory capacity of the first electronic device set at the intersection to be larger than the memory capacity of the first electronic device set at the roadside can adapt to the situation where the first electronic device set at the intersection has a large amount of data throughput per unit time, so as to support high concurrent data processing requirements. Among them, the memory capacity includes the read-only memory capacity (ROM) and the random access memory capacity (RAM).

[0054] During the period when the intersection allows passage, the first electronic device 402 set at the intersection can obtain the identification information of vehicles entering its coverage area and send the identifier, identification information and acquisition time of the first electronic device set at the intersection to the control center.

[0055] like Figure 4 As shown, the distance between the first electronic device 402 and the stop line 401 at the intersection is greater than the coverage range of the first electronic device 402. Thus, if the vehicle represented by the slave device 26 is waiting for a red light in the lane, the slave device 26 does not cross the stop line, and the first electronic device 402 at the intersection cannot detect the identification information of the slave device 26.

[0056] However, if during the period when the intersection is prohibited from passing, the first electronic device 402 set at the intersection obtains the identification information represented by the slave device 26, the first electronic device 402 set at the intersection marks the slave device 26, and the first electronic device 402 set at the intersection sends the marked vehicle to the control center, determining that the marked vehicle has run a red light.

[0057] In this way, the first electronic device installed at the intersection can identify the behavior of vehicles running red lights, thereby improving the accuracy of violation identification.

[0058] In some optional implementations, the multiple access technologies include Star Flash Multi-Link MLE access technology and Star Flash Low Power SLE access technology.

[0059] In this embodiment, Star Flash technology is a new generation of short-range wireless connection technology with the advantages of ultra-low latency, ultra-high reliability, precise synchronization, low power consumption, high speed and wide coverage. In terms of transmission speed, in Star Flash SLE mode, the air interface code rate can reach 12Mbps, which is 6 times that of Bluetooth; in Star Flash MLE mode, the air interface code rate can reach 1.2Gbps, which is twice that of WiFi. In terms of transmission delay, in Star Flash SLE mode, the delay can be reduced to 1ms, which is 1 / 10 of Bluetooth; in Star Flash MLE mode, the delay can be reduced to 10ms, which is 1 / 10 of WiFi. In terms of anti-interference capability, in Star Flash SLE mode, the anti-interference capability is 7dB higher than Bluetooth; in Star Flash MLE mode, the anti-interference capability is 10dB higher than WiFi. In terms of signal coverage range, in Star Flash SLE mode, the coverage distance is twice that of Bluetooth; in Star Flash MLE mode, the coverage distance is 4 times that of WiFi. In terms of the number of device connections, Star Flash technology supports up to 4096 devices connected, while the maximum number of Bluetooth connections is generally 8 and the maximum number of WiFi connections is 256.

[0060] The First Electronic Device uses Star Flash technology to achieve vehicle access, which can improve detection accuracy. The high-precision data transmission and synchronization characteristics of Star Flash technology enable the data collected by the First Electronic Device to be accurately and promptly transmitted to the control center, thereby improving the accuracy of driving regulations detection. At the same time, it can also enhance the real-time nature of driving regulations detection. The ultra-low latency Star Flash communication link ensures that the control center can obtain the vehicle's driving status information in real time, promptly detect violations and report them, effectively improving the real-time nature and response speed of traffic safety management. In addition, the scope of supervision can be expanded. With the wide coverage and multi-connection characteristics of Star Flash technology, a large number of vehicles can be monitored and managed at the same time, realizing large-scale and centralized supervision of vehicle driving regulations, which helps to improve the safety and orderliness of the entire transportation system.

[0061] In related technologies, electric vehicles are smaller than motor vehicles and have flexible driving routes. They often do not follow traffic management regulations. A lot of manpower and material resources must be invested on each road to identify violations and regulate vehicle driving.

[0062] In some optional implementations, the vehicle referred to in the embodiments of the present invention is an electric vehicle, and the identification information of the electric vehicle can be updated based on a preset time period.

[0063] In this implementation, the MAC address of an electric vehicle can be reset weekly or monthly, and the MAC address of the electric vehicle can be bound to the electric vehicle license plate number and owner information. This can fully record the driving characteristics of the electric vehicle, facilitate the tracing of violations, and at the same time, alleviate data storage pressure.

[0064] Applying the vehicle traffic management method of the embodiment of the present invention to electric vehicles can regulate the driving behavior of electric vehicles based on Star Flash technology, eliminating behaviors such as running red lights, driving against traffic, or making illegal U-turns. Furthermore, the first electronic device uses Star Flash technology to connect to electric vehicles, which is low-cost, convenient for Star Flash networking, and can access a large number of terminals, making it more suitable for solving the problem of irregular driving of electric vehicles.

[0065] In some optional embodiments, determining the number of first electronic devices and the locations of the first electronic devices based on the road length and coverage range includes: calculating the coverage radius and deployment density of the first electronic devices based on the road length and the wireless signal attenuation model; and determining the number of first electronic devices and the locations of the first electronic devices based on the coverage radius and the deployment density.

[0066] In this embodiment, the theoretical coverage radius of the first electronic device can be calculated based on the free space propagation model, and the deployment density of the first electronic device can be obtained based on the road length and the theoretical coverage radius. The deployment density N can be calculated using the following formula:

[0067]

[0068] Among them, L is used to represent the road length, R is used to represent the theoretical coverage radius, and α is used to represent the coverage overlap rate of adjacent devices.

[0069] In this way, the reliability of data collection can be improved and the coverage blind area of the first electronic device can be reduced.

[0070] In this embodiment, a method for vehicle traffic management is also provided, which can be used in a control center. Figure 5 A flow chart of a method for vehicle traffic management according to an embodiment of the present invention is shown. Figure 5 As shown, the process includes the following steps:

[0071] Step S501: The control center receives first electronic device identifiers, vehicle identification information, and an acquisition time of the identification information from a plurality of first electronic devices.

[0072] In this step, the control center can be set based on the area. For example, if a street includes three main roads, a control center can be defined within the street area. The first electronic device identifier can be the MAC address of the first electronic device, and the vehicle identification information can be the MAC address of the vehicle.

[0073] In step S502, the control center determines the driving trajectory of the target vehicle based on the first electronic device identifier, identification information, and acquisition time, and determines whether the target vehicle is driving against traffic or making an illegal U-turn based on the driving trajectory.

[0074] In this step, the control center can obtain the driving trajectory of the slave device based on the time sequence of the multiple first electronic devices being triggered. Figure 2 As shown, if the driving direction that complies with road traffic management regulations is, Figure 2 From right to left, for the identification information (from device 26), in chronological order, the order of the identifiers of the first electronic device obtained is first electronic device 1 (21) → first electronic device 2 (22) → first electronic device 3 (23). It can be obtained that the driving trajectory of the slave device 26 represented by the identification information is from right to left, and the target vehicle from device 26 does not have the behavior of going against traffic or making an illegal U-turn.

[0075] Otherwise, the target vehicle may have the behavior of going against traffic or making a U-turn from the device 26, and the driver of the target vehicle may be reminded in the form of a text message, or the behavior of going against traffic or making an illegal U-turn may be sent to the relevant traffic management department.

[0076] In this way, the control center can detect the driving trajectory of electric vehicles, solve the shortcomings of related technologies in the standardized detection of electric vehicles, realize comprehensive, real-time and accurate detection of the driving process of electric vehicles, and improve the level of traffic safety management.

[0077] In some optional embodiments, Figure 5 The characterized method for vehicle traffic management also includes: the control center determines the driving speed of the target vehicle based on the identification information and the acquisition time, and based on the driving speed, determines whether the target vehicle has a behavior of exceeding a preset driving speed.

[0078] In this embodiment, since the locations of each first electronic device are known and fixed, the target vehicle's speed can be estimated based on the known distances between the first electronic devices and the time reported by the first electronic devices when the target vehicle entered the coverage area of each first electronic device. The preset speed can be determined based on relevant road management regulations.

[0079] In this way, the speed of electric vehicles can be further detected, and the level of traffic safety management can be further improved.

[0080] This embodiment also provides a system for vehicle traffic management. This device is used to implement the above-mentioned embodiments and preferred embodiments. Details already described will not be repeated here. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0081] This embodiment provides a system for vehicle traffic management. Figure 6 FIG. 1 shows a schematic diagram of a system for vehicle traffic management according to an embodiment of the present invention. Figure 6 Shown, including:

[0082] A first electronic device 601 is provided on the roadside and supports multiple access technologies. The first electronic device 601 selects a first access technology from the multiple access technologies. The first electronic device 601 obtains identification information of vehicles 602 that enter the coverage area of the first electronic device 601 based on the first access technology. The first electronic device 601 determines the number and location of the first electronic device 601 based on the road length and the coverage area, and whether the vehicles 602 support the first access technology. The first electronic device 601 transmits the identification information of the vehicles 602 and the time at which the identification information of the vehicles 602 was obtained to the control center 603.
