In the following method embodiments, for convenience of description, only the execution subject of each step is described as a server.
Please refer to fig. 2, which is a flowchart illustrating a method for early warning vehicles on a highway according to an embodiment of the present disclosure. As shown in fig. 2, the method of the embodiment of the present application may include the steps of:
s201, vehicle running information from the vehicle-mounted terminal is received.
The vehicle driving information is the driving information of the vehicle on the expressway and comprises one or more of the vehicle position, the vehicle speed and the driving direction.
Generally, a server establishes a DM (Device Management) session with a vehicle-mounted terminal, and receives vehicle travel information transmitted from the vehicle-mounted terminal based on the DM session. The DM is a set of protocols, which are derived based on the OMA (Open Mobile Alliance) protocol and are specially used for terminal management, and defines a set of standards for information interaction between the server and the terminal. OMA DM is a protocol for managing terminals in a network via a remote server. The vehicle-mounted terminal comprises a user terminal and a vehicle terminal, and the user terminal and the vehicle terminal are used for collecting driving information of a vehicle on a highway.
Before the vehicle runs, the user can set the relevant information of the vehicle and the personal information of the driver in an application program installed on the user terminal, such as the personal information of the driver, including name, mobile phone number, identification number and the like; the relevant information of the vehicle can include the model of the vehicle, the license plate number, the safe distance during the running of the vehicle and the like. After the user sets the information, the user terminal sends the information to the server.
In the driving process of the vehicle, the vehicle terminal collects the position information, the speed and the driving direction of the vehicle in real time and sends the information to the server.
And S202, detecting whether the vehicle meets a collision early warning condition according to the vehicle running information.
Generally, after receiving vehicle driving information sent by a vehicle-mounted terminal, a server determines a safe distance of a current vehicle, monitors vehicles in the same lane as the current vehicle, detects a distance between the vehicle and the current vehicle, determines that the vehicle and the current vehicle have a risk of collision when the determined distance is smaller than the safe distance, and determines that a collision early warning condition is met. The safe distance may be set by the user before the vehicle travels, or may be calculated by the server based on the travel information of the vehicle during travel.
And S203, if so, sending collision early warning information to the vehicle-mounted terminal.
And based on the fact that the current vehicle meets the collision early warning condition determined by S202, sending collision early warning information to the vehicle-mounted terminal through the 5G network.
When the scheme of the embodiment of the application is executed, vehicle running information from a vehicle-mounted terminal is received; wherein the vehicle travel information includes one or more of a vehicle location, a vehicle speed, and a travel direction; detecting whether the vehicle meets a collision early warning condition according to the vehicle running information; and if so, sending collision early warning information to the vehicle-mounted terminal. The server detects whether the vehicle can collide according to the vehicle running information by receiving the vehicle running information sent by the vehicle-mounted terminal, and if the vehicle can collide, the server sends collision early warning information to the vehicle-mounted terminal, so that a driver can know the situation after the vehicle is removed, the early warning capability is improved, and traffic accidents are reduced.
Please refer to fig. 3, which is a flowchart illustrating a method for early warning vehicles on a highway according to an embodiment of the present disclosure. As shown in fig. 3, the method of the embodiment of the present application may include the steps of:
s301, receiving a DM session request from the vehicle-mounted terminal, verifying the vehicle-mounted terminal, and performing a DM session with the vehicle-mounted terminal.
Generally, a DM session request refers to a vehicle-mounted terminal sending a request to a server to start a session initiated by the vehicle-mounted terminal, the server identifying and authenticating the vehicle-mounted terminal, sending a DM command to the vehicle-mounted terminal, the vehicle-mounted terminal executing the specified DM command, the vehicle-mounted terminal sending a result of the operation on the DM command to the server, and finally the server returning the DM command to the vehicle-mounted terminal to terminate the management session.
The method is based on an Open Mobile Alliance (OMA) terminal Management (DM) protocol to transmit data, and a data interaction process of the OMA DM protocol comprises two stages, namely a preparation stage which mainly transmits authentication and equipment information; the second is a management phase, which is a large number of interactive processes. The management stage consists of one or more protocol iterations, wherein the protocol iterations refer to messages sent by the terminal to the server, and then the server sends back the messages to the terminal. The content in the message packet sent by the server to the terminal determines whether the current session is to be ended, if the message packet sent by the server contains a management command which needs the terminal to respond, the terminal sends a new message packet to the server in the protocol management stage, the message packet contains a response to the management command of the server, the response to the management command starts a new protocol iteration, and the server can send a new management command message packet, so that a plurality of protocol iteration processes which are needed by the server can be initialized. If the message sent by the server does not contain the management command which needs the terminal to respond, the terminal creates a message packet only containing Status and SyncHdr responses and sends the message packet back to the server. At this point, the response message packet is no longer sent and the protocol ends. The terminal and the server can freely select the execution order of the management commands in the message packet if the management commands are not specifically described, but must execute in the order in which the management commands are transmitted if the execution order is specified in the parent management command.
S302, vehicle travel information from the in-vehicle terminal is received based on the DM session.
The vehicle driving information is driving information of the vehicle in the driving process of the expressway, and comprises one or more of vehicle position, vehicle speed and driving direction. The vehicle driving information may further include personal information of a driver of the vehicle, including a name, a mobile phone number, identity information, and the like of the driver, and the vehicle driving information may further include basic information of the vehicle, including a vehicle model, a license plate number, and the like.
Generally, after the server establishes a DM session with the in-vehicle terminal, vehicle travel information transmitted from the in-vehicle terminal is received.
S303, determining the safety distance.
The safe distance refers to a distance when emergency stopping is carried out to avoid causing safety accidents under emergency conditions.
In one possible embodiment, the safe distance may be calculated by the server based on the relative speed of the vehicles. The server acquires the running speed and the running direction of the current vehicle and other vehicles, further can acquire the relative speed and the relative direction between the current vehicle and other vehicles, and can calculate according to the relative speed and the relative direction to obtain the safe distance of the current vehicle.
In a possible implementation manner, the safe distance may be set by the user in the application before the vehicle travels, because the driving level and the driving habit of each person are different, when the server calculates the safe distance, a larger safe distance may sometimes be calculated, a problem of false alarm may exist, a smaller safe distance may sometimes be calculated, and the purpose of early warning may not be achieved. Therefore, the driver can set the safe distance according to the self level and habit.
And S304, when the distance between the vehicle and one or more adjacent vehicles is less than the safe distance, determining that the collision early warning condition is met.
Generally, when monitoring an adjacent vehicle in the same lane as the current vehicle, the server determines that a collision may occur when calculating that the distance between the vehicle and the current vehicle is less than a safe distance, and meets the condition that the server sends a collision warning prompt message to the vehicle-mounted terminal.
And S305, sending collision early warning information to the vehicle-mounted terminal through the 5G network.
The collision early warning information is used for indicating a prompt unit of the vehicle-mounted terminal to send out an early warning sound signal and/or a vibration signal. The vehicle-mounted terminal comprises a vehicle terminal and a user terminal, and the early warning prompt message can instruct the vehicle terminal to send out an early warning sound signal and can also instruct the user terminal to send out an early warning sound signal or a vibration signal.
S306, when the traffic accident alarm event sent by the vehicle-mounted terminal is received, historical vehicle running information reported by the vehicle terminal in a preset time period is obtained.
The historical vehicle driving information refers to a driving distance of the vehicle-mounted terminal in a preset time period and comprises driving speed, driving direction and position information.
Generally, when a traffic accident occurs, a user can report to a server by pressing an alarm button on a vehicle terminal and can also report to the server by pressing an alarm button on a mobile phone terminal. The server acquires historical vehicle running information reported by the vehicle terminal within a preset time period after receiving a traffic accident alarm event sent by the vehicle terminal.
And S307, determining the dynamic driving track of the vehicle.
In general, the server may determine a dynamic trajectory of the vehicle based on the time and the vehicle travel information over the corresponding time.
And S308, reporting the dynamic driving track, the driver identity information and the vehicle identity information to a traffic alarm system.
The driver identity information comprises a driver name, a mobile phone number, identity card information and the like, and the vehicle identity information comprises a vehicle model number, a license plate number and the like. When a traffic accident occurs, the traffic police system can give an alarm and judge responsibility according to the dynamic driving track, and can quickly contact with a responsible person to perform processing such as responsibility pursuit according to the vehicle identity information and the driver identity information.
When the scheme of the embodiment of the application is executed, vehicle running information from a vehicle-mounted terminal is received; wherein the vehicle travel information includes one or more of a vehicle location, a vehicle speed, and a travel direction; detecting whether the vehicle meets a collision early warning condition according to the vehicle running information; and if so, sending collision early warning information to the vehicle-mounted terminal. The server detects whether the vehicle can collide according to the vehicle running information by receiving the vehicle running information sent by the vehicle-mounted terminal, and if the vehicle can collide, the server sends collision early warning information to the vehicle-mounted terminal, so that a driver can know the situation after the vehicle is removed, the early warning capability is improved, and traffic accidents are reduced.
