Description

Technical Field

[0001] The present invention relates to the field of intelligent transportation technology, and in particular to a low-latency intelligent transportation safety detection and early warning method and system. Background Art

[0002] The characteristics of regional development in cities are more obvious, making urban public transportation congestion more serious. Intelligent transportation technology has emerged. With the promotion and application of intelligent transportation technology, in order to facilitate more users to choose public transportation, it is necessary to design more complex bus routes and arrange bus stations more closely. At the same time, in order to facilitate users to understand the operation of each bus route in real time through smart terminals, so as to choose the most reasonable bus route for travel, it is necessary to obtain the bus stop status of each bus station more timely.

[0003] At present, many bus stops allow buses of multiple bus lines to stop at the same time period, and it takes a lot of time for passengers to get on and off the bus, which makes it very easy for traffic congestion to occur near many bus stops. At the same time, many non-bus motor vehicles such as private cars and online car-hailing vehicles also need to pass through bus stops when planning navigation routes. Since the navigation routes of many non-bus motor vehicles only need to pass through bus stops, they do not completely need to use bus lanes to make right turns. Many non-bus motor vehicles temporarily pass through bus stops to change lanes and overtake. For this reason, some people have proposed installing surveillance cameras at bus stops to cooperate with traffic management and prompt warning. However, this solution requires the collection of video image data, and the hardware cost required for its data processing is high, and there is a high delay. Even if the relevant non-bus motor vehicles can be prompted, the real-time performance is difficult to guarantee. Therefore, a low-latency intelligent traffic safety detection and early warning solution is needed. Summary of the invention

[0004] The purpose of the present invention is to provide a low-latency intelligent traffic safety detection and early warning method and system, which can realize safety detection and low-latency early warning of non-bus motor vehicles near bus stops without collecting and analyzing video images of bus stops, thereby alleviating traffic congestion near bus stops.

[0005] The present invention solves the technical problem and adopts the following technical solution:

[0006] On the one hand, the present invention provides a low-latency intelligent traffic safety detection and early warning method, comprising the following steps:

[0007] The navigation server receives the client navigation route information of the non-public transport vehicle selected by the client and the vehicle navigation route information of the non-public transport vehicle, and screens out the client and the non-public transport vehicle to pass through the bus station unit, and sends the screening result to the bus management platform;

[0008] Obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time through the bus management platform, filter out the bus stop units used for networking, send a networking notification to the bus stop units used for networking, and synchronize the screening results to the bus stop units used for networking after receiving them;

[0009] The bus station unit forms a network after receiving the networking notification, and the networked bus station unit broadcasts the request instruction externally;

[0010] When the bus unit receives the request command, it determines that the signal strength of the request command reaches the preset signal strength, obtains the real-time location information of the bus unit, and sends a reply command to the bus stop unit;

[0011] When the bus stop unit receives a reply instruction, it determines that the number of reply instructions has reached a preset number, and then sends a recommended lane instruction to the clients and non-bus motor vehicles that are about to pass through the bus stop within the communication range, and instructs the clients and non-bus motor vehicles that are about to pass through the bus stop to choose a non-bus lane to pass through the bus stop unit through the recommended lane instruction.

[0012] Furthermore, before the navigation server screens out the client and the non-public transport vehicle to be passed through the bus stop unit, the method further includes:

[0013] The navigation server obtains the location information of the bus stop unit from the bus management platform.

[0014] Furthermore, when the location information of the bus stop unit changes, the changed location information of the bus stop is synchronized to the bus management platform.

[0015] Furthermore, when the navigation server screens out the client and the non-public transport vehicle to be passed through the bus stop unit, it also includes:

[0016] The navigation server calculates the time for the client and non-bus motor vehicles to pass through the bus station unit according to the client navigation route information and the vehicle navigation route information.

[0017] Furthermore, after the client and non-bus motor vehicles passing through the bus station select the non-bus lane to pass through the bus station unit, the client navigation route information and the vehicle navigation route information are updated and sent to the navigation server.

[0018] Furthermore, the obtaining of information on the number of buses that are to arrive at the same bus stop unit within a specified time through the bus management platform and screening out the bus stop units for networking refers to:

[0019] The public management platform stores bus route information and bus schedule information of different routes. The bus route information and bus schedule information of different routes are used to obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time. When the number of buses that are expected to arrive at the same bus stop unit within the specified time reaches a specified number, the bus stop unit is used as a screened bus stop unit for networking.

[0020] Furthermore, the bus station unit performs networking after receiving the networking notification, and the networked bus station unit broadcasts the request instruction externally, which means:

[0021] After receiving the networking notification, the bus station unit sequentially establishes a unidirectional wireless local area network between the current bus station unit for networking and the next bus station unit for networking according to the bus route direction;

[0022] After the bus stop unit currently used for networking broadcasts a request instruction, it notifies the next bus stop unit used for networking to broadcast a request instruction through a one-way wireless local area network. The broadcast request instruction contains the unique identifier of the bus stop unit currently used for networking.

[0023] Furthermore, when the bus unit receives the request instruction, it determines that the signal strength of the request instruction reaches a preset signal strength, obtains the real-time location information of the bus unit, and sends a reply instruction to the bus stop unit, which means:

[0024] When the bus station unit of the network sends a broadcast request instruction to the outside, the unique identification of each bus station unit used for networking is sent to the corresponding bus unit through the bus management platform;

[0025] When the bus unit receives a request instruction, if it is determined that the request instruction contains the unique identifier of the bus stop unit currently used for networking, it determines whether the signal strength of the request instruction reaches the preset signal strength. When it reaches the preset signal strength, it obtains the real-time location information of the bus unit and sends a reply instruction to the bus stop unit currently used for networking, wherein the reply instruction contains the unique identifier of the current bus unit.

[0026] Furthermore, when the bus stop unit receives the reply instruction, after determining that the number of reply instructions reaches a preset number, it sends a recommended lane instruction to the client and non-bus motor vehicle to be passed through the bus stop within the communication range, and instructs the client and non-bus motor vehicle to be passed through the bus stop to choose the non-bus lane to pass through the bus stop unit through the recommended lane instruction, which means:

[0027] The bus management platform pre-stores unique identifiers of all bus units;

[0028] After the bus station unit for networking is screened out by the bus management platform, the unique identifiers of all bus units stored in advance are sent to the bus station unit for networking respectively and stored in the form of an identifier storage list;

[0029] When the bus stop unit receives a reply instruction, if it is determined that the unique identifier of the bus unit contained in the reply instruction belongs to an identifier in the identifier storage list, it is determined whether the number of reply instructions reaches a preset number. When it reaches a preset number, a recommended lane instruction is sent to the clients and non-bus motor vehicles to be passed through the bus stop within the communication range, and the recommended lane instruction is used to instruct the clients and non-bus motor vehicles to be passed through the bus stop to choose a non-bus lane to pass through the bus stop unit.

[0030] On the other hand, the present invention also provides a low-latency intelligent traffic safety detection and early warning system, which is applied to the low-latency intelligent traffic safety detection and early warning method, comprising:

[0031] The navigation server is used to receive the client navigation route information of the non-public transport vehicle selected by the client and the vehicle navigation route information of the non-public transport vehicle, and screen out the client and the non-public transport vehicle to pass through the bus station unit, and send the screening result to the bus management platform;

[0032] The bus management platform is used to obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time, screen out the bus stop units used for networking, send a networking notification to the bus stop units used for networking, and synchronize the screening results to the bus stop units used for networking after receiving them;

[0033] The bus station unit is used to establish a network after receiving a networking notification. The networked bus station unit broadcasts a request instruction to the outside, and is used to receive a reply instruction, and after determining that the number of reply instructions reaches a preset number, sends a recommended lane instruction to the client and non-bus motor vehicle to be passed through the bus station within the communication range, and instructs the client and non-bus motor vehicle to be passed through the bus station to choose a non-bus lane to pass through the bus station unit through the recommended lane instruction;

[0034] The bus unit is used to, when receiving a request instruction, determine that the signal strength of the request instruction reaches a preset signal strength, obtain the real-time location information of the bus unit, and send a reply instruction to the bus stop unit.

[0035] The beneficial effects of the present invention are as follows: through the above-mentioned low-latency intelligent traffic safety detection and early warning method and system, firstly, the navigation route information of the client selected by the client for using non-public transport vehicles and the on-board navigation route information of non-public transport vehicles are received through the navigation server, and the clients and non-public transport vehicles to be passed through the bus stop unit are screened out, and the screening results are sent to the bus management platform; secondly, the bus management platform obtains the number of buses that are to arrive at the same bus stop unit within a specified time, screens out the bus stop units for networking, sends a networking notification to the bus stop units for networking, and sends the same to the bus stop units after receiving the screening results. Step to the bus station unit for networking; then, the bus station unit conducts networking after receiving the networking notification, and the networked bus station unit broadcasts the request instruction to the outside; when the bus unit receives the request instruction, it determines that the signal strength of the request instruction reaches the preset signal strength, obtains the real-time location information of the bus unit, and sends a reply instruction to the bus station unit; when the bus station unit receives the reply instruction, it determines that the number of reply instructions reaches the preset number, and sends a recommended lane instruction to the client and non-bus motor vehicle to be passed through the bus station within the communication range, and instructs the client and non-bus motor vehicle to be passed through the bus station to choose the non-bus lane to pass through the bus station unit through the recommended lane instruction.

[0036] Therefore, the present invention establishes information exchange between the bus management platform and the navigation server, and instructs the client and non-bus motor vehicles to pass through the bus station to choose non-bus lanes to pass through the bus station unit in combination with the specific conditions of different bus stop units and the real-time conditions of the buses. There is no need to set up surveillance cameras in the bus stop, nor is there any need to collect and process video images from the surveillance cameras. Therefore, the present invention greatly reduces the delay when performing intelligent traffic safety detection and early warning. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 2 The figure is a schematic diagram of the composition structure of a low-latency intelligent traffic safety detection and warning system in the second embodiment of the present invention. DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Embodiment 1

[0041] This embodiment provides a low-latency intelligent traffic safety detection and early warning method, and its flow chart is shown in Figure 1 , wherein the method comprises the following steps:

[0042] S1. Receive, through a navigation server, client navigation route information of non-public transport vehicles selected by the client and vehicle-mounted navigation route information of non-public transport vehicles, and screen out clients and non-public transport vehicles to pass through bus stop units, and send the screening results to the bus management platform;

[0043] S2. Obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time through the bus management platform, filter out the bus stop units used for networking, send a networking notification to the bus stop units used for networking, and synchronize the screening results to the bus stop units used for networking after receiving them;

[0044] S3, the bus station unit conducts networking after receiving the networking notification, and the networked bus station unit broadcasts the request instruction externally;

[0045] S4, when the bus unit receives the request command, it determines that the signal strength of the request command reaches the preset signal strength, obtains the real-time location information of the bus unit, and sends a reply command to the bus station unit;

[0046] S5. When the bus stop unit receives a reply instruction, it determines that the number of reply instructions reaches a preset number, and then sends a recommended lane instruction to the clients and non-bus motor vehicles that are about to pass through the bus stop within the communication range, and instructs the clients and non-bus motor vehicles that are about to pass through the bus stop to choose a non-bus lane to pass through the bus stop unit through the recommended lane instruction.

[0047] In this embodiment, non-public transport motor vehicles, such as private cars and online-hailing taxis, will most likely use on-board navigation software for navigation, and some will also use the user's smart terminal as a client and use the navigation software in the smart terminal for navigation. Therefore, these non-public transport motor vehicles may pass through the bus stop unit when generating the corresponding navigation route. In this case, many non-public transport motor vehicles will temporarily occupy the bus lane on the side of the bus stop unit, and may stop temporarily or temporarily overtake. At present, due to the improvement of the road monitoring mechanism, most of them use the installation of surveillance cameras to complete the monitoring and early warning of these traffic violations. However, at this time, the surveillance camera needs to collect and process video images, which requires a long processing time, resulting in many non-public transport motor vehicles unable to receive early warnings and prompts in time. Therefore, the present invention abandons the traditional high-latency image acquisition and processing solution.

[0048] Although some non-public transport vehicles use on-board navigation and some use clients for navigation, and the manufacturers of the navigation software used may not be the same, each manufacturer will use a navigation server to back up the navigation route information of the current manufacturer, so that the public transport management platform can more easily obtain the actual situation of non-public transport vehicles. However, due to the large number of non-public transport vehicles and clients, if each on-board navigation data or client navigation data is synchronized to the public transport management platform, it will cause huge data processing pressure and data storage pressure to the public transport management platform, and not all navigation routes will pass through the bus stop unit. Therefore, this embodiment needs to first screen out the clients and non-public transport vehicles that are to pass through the bus stop unit, and then synchronize them to the public transport management platform.

[0049] It should be pointed out that although the location information of the bus stop unit is relatively fixed, it may also change temporarily with the arrangement of bus schedules or road maintenance. Although the navigation server will pre-store the location information of many urban roads and related bus stops, its information may be lagging. When the location information of the bus stop unit changes, the bus management platform will mostly synchronize the information first. Therefore, in this embodiment, before the navigation server screens out the client and non-bus motor vehicles to pass through the bus stop unit, it also includes: the navigation server obtains the location information of the bus stop unit from the bus management platform. At the same time, when the location information of the bus stop unit changes, the location information of the changed bus stop is synchronized to the bus management platform.

[0050] Generally speaking, whether it is in-vehicle navigation or client navigation, after entering the departure and destination, the corresponding navigation route information will be obtained, and the approximate time information will also be obtained. Since many bus stop units have not yet synchronously configured special cameras for temporary occupation of bus lanes, in order to reach the destination as soon as possible, many navigation routes may also have temporary occupation of bus lanes. In this embodiment, it is necessary to prompt these non-bus motor vehicles passing through the bus stop unit to drive through the regular motor vehicle lane. Therefore, after the non-bus motor vehicle passes through the bus stop unit, its estimated arrival time at the destination may change, and it is determined based on the regular motor vehicle lane selected by the non-bus motor vehicle in the bus stop unit. Therefore, it is necessary to know the time when the non-bus motor vehicle passes through the bus stop unit. Therefore, in this embodiment, when the navigation server screens out the client and non-bus motor vehicles to pass through the bus stop unit, it can also include: the navigation server calculates the time when the client and non-bus motor vehicle to pass through the bus stop unit according to the client navigation route information and the in-vehicle navigation route information.

[0051] At the same time, in order to achieve information synchronization between the navigation server and the on-board navigation software of non-public transport vehicles and the navigation software of the client as much as possible, in this embodiment, after the client and non-public transport vehicles passing through the bus station choose the non-public transport lane to pass through the bus station unit, the client navigation route information and the on-board navigation route information are updated and sent to the navigation server.

[0052] It should be pointed out that, since the bus stop units are screened in this embodiment, after screening, the bus stop units will be used as nodes for subsequent networking. In the process of wireless local area networking, in order to ensure that each bus stop unit in the networking completes efficient instruction sending and receiving work as much as possible, the communication distance between adjacent nodes cannot be set too long. Therefore, in this embodiment, the bus management platform is used to obtain the number of buses that are expected to arrive at the same bus stop unit within a specified time, and the bus stop units used for networking are screened out, which may refer to:

[0053] The public management platform stores bus route information and bus schedule information of different routes. The bus route information and bus schedule information of different routes are used to obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time. When the number of buses that are expected to arrive at the same bus stop unit within the specified time reaches a specified number, the bus stop unit is used as a screened bus stop unit for networking.

[0054] In addition, the bus station unit performs networking after receiving the networking notification, and the networked bus station unit broadcasts the request instruction externally, which may refer to:

[0055] After receiving the networking notification, the bus station unit sequentially establishes a unidirectional wireless local area network between the current bus station unit for networking and the next bus station unit for networking according to the bus route direction;

[0056] After the bus stop unit currently used for networking broadcasts a request instruction, it notifies the next bus stop unit used for networking to broadcast a request instruction through a one-way wireless local area network. The broadcast request instruction contains the unique identifier of the bus stop unit currently used for networking.

[0057] Here, since there may be a load and numerous broadcast instructions in the space, if the broadcast request instruction is not limited by a unique identifier, there may be a risk of receiving erroneous instructions or being invaded by malicious instructions when sending and receiving instructions in this embodiment. Therefore, in this embodiment, the broadcast request instruction should include the unique identifier of the bus stop unit currently used for networking, and the reply instruction should include the unique identifier of the current bus unit.

[0058] Specifically, in this embodiment, when the bus unit receives the request instruction, it determines that the signal strength of the request instruction reaches the preset signal strength, obtains the real-time location information of the bus unit, and sends a reply instruction to the bus station unit, which may refer to:

[0059] When the bus station unit of the network sends a broadcast request instruction to the outside, the unique identification of each bus station unit used for networking is sent to the corresponding bus unit through the bus management platform;

[0060] When the bus unit receives a request instruction, if it is determined that the request instruction contains the unique identifier of the bus stop unit currently used for networking, it determines whether the signal strength of the request instruction reaches the preset signal strength. When it reaches the preset signal strength, it obtains the real-time location information of the bus unit and sends a reply instruction to the bus stop unit currently used for networking, wherein the reply instruction contains the unique identifier of the current bus unit.

[0061] It should be noted that in this embodiment, when the bus station unit receives the reply instruction, after determining that the number of reply instructions reaches a preset number, it sends a recommended lane instruction to the client and non-bus motor vehicle to be passed through the bus station within the communication range, and instructs the client and non-bus motor vehicle to be passed through the bus station to choose the non-bus lane to pass through the bus station unit through the recommended lane instruction, which may refer to:

[0062] The bus management platform pre-stores unique identifiers of all bus units;

[0063] After the bus station unit for networking is screened out by the bus management platform, the unique identifiers of all bus units stored in advance are sent to the bus station unit for networking respectively and stored in the form of an identifier storage list;

[0064] When the bus stop unit receives a reply instruction, if it is determined that the unique identifier of the bus unit contained in the reply instruction belongs to an identifier in the identifier storage list, it is determined whether the number of reply instructions reaches a preset number. When it reaches a preset number, a recommended lane instruction is sent to the clients and non-bus motor vehicles to be passed through the bus stop within the communication range, and the recommended lane instruction is used to instruct the clients and non-bus motor vehicles to be passed through the bus stop to choose a non-bus lane to pass through the bus stop unit.

[0068] The bus management platform is used to obtain information on the number of buses that are expected to arrive at the same bus stop unit within a specified time, screen out the bus stop units used for networking, send a networking notification to the bus stop units used for networking, and synchronize the screening results to the bus stop units used for networking after receiving them;

[0069] The bus station unit is used to establish a network after receiving a networking notification. The networked bus station unit broadcasts a request instruction to the outside, and is used to receive a reply instruction, and after determining that the number of reply instructions reaches a preset number, sends a recommended lane instruction to the client and non-bus motor vehicle to be passed through the bus station within the communication range, and instructs the client and non-bus motor vehicle to be passed through the bus station to choose a non-bus lane to pass through the bus station unit through the recommended lane instruction;
