The embodiment of the application provides a Beidou early warning system, which comprises an early warning platform and a vehicle-mounted terminal arranged on a vehicle, and the Beidou early warning system CAN be considered that the early warning platform is used as a platform for data processing, and CAN be a computer, a server and other devices with data processing functions, while the vehicle-mounted terminal is used for acquiring vehicle information related to the vehicle, such as positioning information, vehicle speed information and the like, on the vehicle, for example, the vehicle-mounted terminal is accessed into a CAN data bus on the vehicle through a CAN interface so as to acquire the vehicle information.
In addition, the data transmission can be carried out between the vehicle-mounted terminal and the early warning platform through a base station, namely, the communication mode between the vehicle-mounted terminal and the early warning platform can be satellite communication or cellular communication. Therefore, the cellular communication module and the satellite communication module are arranged on the vehicle-mounted terminal and the equipment corresponding to the early warning platform, so that satellite communication and cellular communication are realized.
Fig. 1 is a flow chart of steps of a traffic early warning method according to an embodiment of the present application, where the traffic early warning method of the present application may be applied to the above-mentioned vehicle-mounted terminal, and as shown in the drawing, the traffic early warning method of the present application includes the following steps:
step S110, receiving communication signals transmitted by the base station.
And step S120, determining the signal strength of the vehicle-mounted terminal according to the communication signal.
After receiving the communication signal, the vehicle-mounted terminal can determine the signal strength of the transmitted wireless signal. Illustratively, the base station transmits a Reference Signal (RS) to the vehicle-mounted terminal, and the vehicle-mounted terminal may measure the Signal strength of the Reference Signal through RSRP (Reference Signal Receiving Power, reference Signal received power) to determine the Signal strength of the wireless Signal for cellular communication. Likewise, the vehicle terminal may also measure the signal strength of the wireless signal through RSSI (Received Signal Strength Indicator, received signal strength indication).
And step S130, dynamically selecting a target communication module from the cellular communication module and the satellite communication module based on the signal intensity of the vehicle-mounted terminal so as to send vehicle information to the early warning platform.
It can be understood that a preset threshold value can be set in the vehicle-mounted terminal, and the preset threshold value is related to the signal intensity of the vehicle-mounted terminal, so that the vehicle-mounted terminal can dynamically select the target communication module from the cellular communication module and the satellite communication module according to the signal intensity, and further, the vehicle information is sent.
In an embodiment, the cellular communication module and the satellite communication module carried on the vehicle-mounted terminal are in a working state at the same time, but the vehicle-mounted terminal needs to judge the target communication module for transmitting data according to the signal strength of the wireless signal so as to realize more effective data transmission.
For example, when the signal strength of the vehicle-mounted terminal is greater than or equal to a preset threshold, the cellular communication module is selected as the target communication module, and the vehicle-mounted terminal is automatically switched to the cellular communication module. And when the signal intensity of the vehicle-mounted terminal is smaller than a preset threshold value, selecting the satellite communication module as a target communication module, and automatically switching the vehicle-mounted terminal to the satellite communication module.
The switching mode can realize the switching of the modules without influencing the normal operation of the vehicle-mounted terminal under the condition of not closing the system power supply, thereby improving the reliability, the quick maintainability, the redundancy, the timely recovery capability to disasters and the like of the vehicle-mounted terminal.
Therefore, the vehicle-mounted terminal can adaptively switch the best signal according to the intensity state of the current signal, is not influenced by the climate environment, has no communication blind area, and can ensure the communication fluency with the early warning platform in the environment without moving signals.
And step 140, outputting an alarm signal when receiving the early warning information sent by the early warning platform.
It is conceivable that the early warning platform is in communication connection with the vehicle-mounted terminal, the early warning platform sends early warning information to the vehicle-mounted terminal after judging that the vehicle has collision risk, and the vehicle-mounted terminal outputs an alarm signal to inform a driver after receiving the early warning information.
Short message communication is adopted between the vehicle-mounted terminal and the Beidou satellite. Short message communication has all weather, wide coverage of the whole area, high reliability and other advantages, so that the short message communication has wide application range, and the Beidou satellite can stably and continuously transmit data in areas where communication cannot be guaranteed by cellular signals such as 4G or 5G. Therefore, the quick response capability of the system is that the short message communication time delay is about 0.5s, and the point-to-point communication time delay is 1-5 s; the communication has strong interference resistance, and meanwhile, the S/L wave band satellite transmission is adopted, so that the communication under extreme weather conditions can be ensured through a stratosphere and a troposphere.
In an embodiment, the vehicle-mounted terminal is further provided with a bluetooth module, and the bluetooth module is in communication connection with the display panel on the console in the vehicle, so that when receiving the early warning information sent by the early warning platform, the vehicle-mounted terminal can output an alarm signal to the display panel, for example, output corresponding characters or icons on the display panel to inform the driver. Or in an embodiment, the vehicle-mounted terminal CAN also control the player on the vehicle to output an alarm signal through the CAN bus, so that the player plays corresponding voice to play a role of informing a driver.
According to the scheme, the vehicle can carry out data transmission through the onboard terminal and the early warning platform, the target communication module with better communication quality is selected according to the signal intensity, so that the data transmission is carried out with the early warning platform, feedback early warning information is timely received when collision risk exists, and further the onboard terminal can output corresponding warning signals, so that a driver can adjust the speed and distance of the vehicle, and collision risk is avoided.
Fig. 2 is a flow chart of steps of a traffic early warning method according to another embodiment of the present application, where the traffic early warning method of the present application can be applied to an early warning platform, and as shown in the figure, the traffic early warning method further includes the following steps:
step S210, receiving vehicle information sent by each vehicle through the vehicle-mounted terminal.
It is contemplated that each vehicle may send vehicle information to the alert platform according to the methods described in the above embodiments, including, but not limited to, vehicle positioning information, vehicle speed information, heading angle, and the like. Vehicle-mounted terminals are arranged on the vehicles, and the vehicle information of the vehicles is received and recorded by the early warning platform so that the early warning platform can early warn the vehicles.
Step S220, based on the positioning information carried by the vehicle information of the corresponding target vehicle, determining the adjacent vehicle corresponding to the target vehicle, wherein the adjacent vehicle is a vehicle within the target range of the target vehicle.
The early warning platform can position the target vehicle according to the positioning information reported by each vehicle-mounted terminal. It will be appreciated that the target vehicle is a vehicle that is currently in need of collision warning. In some embodiments, the device on which the alert platform resides may handle the alert needs of each vehicle at the same time, it being contemplated that for each vehicle it is the target vehicle.
Therefore, after determining the position of the target vehicle, the early warning platform can determine the vehicle within the target range of the target vehicle according to the positioning information of the target vehicle and other vehicles. It is conceivable that the target range is a range set corresponding to the collision risk, that is, when the other vehicle is located within the target range of the target vehicle, the target vehicle has a collision risk with the other vehicle.
In some embodiments, the target range of the target vehicle may change as the speed of the target vehicle changes, for example, when the speed of the target vehicle increases, and accordingly, the radius corresponding to the target range increases, i.e., the two are in positive correlation. That is, the target range may be a range that dynamically changes in response to the vehicle speed to provide more effective collision warning.
Step S230, according to the vehicle information of the adjacent vehicles, collision early warning is carried out on the target vehicle so as to determine whether the target vehicle has collision risk.
When the early warning platform carries out collision early warning on the target vehicle, the early warning platform is also combined with the vehicle information of the adjacent vehicle to determine whether the target vehicle has collision risk. For example, the speed of the target vehicle and the speed of the adjacent vehicles are combined, and based on the running directions of the two vehicles, whether the two vehicles collide or not is further judged, specifically, if a junction exists in the running directions of the two vehicles, the time for the two vehicles to pass through the junction can be calculated through the corresponding speed, and whether collision risks exist or not is further judged.
And step 240, if the target vehicle has collision risk, sending early warning information to the vehicle-mounted terminal of the target vehicle through the Beidou satellite and the base station.
It can be understood that the early warning platform adopts a double-link to send early warning information when determining that the target vehicle has collision risk, so that the vehicle-mounted terminal can receive the early warning information and carry out warning.
It is conceivable that, likewise, all be provided with cellular communication module and satellite communication module on the equipment that early warning platform corresponds, early warning platform passes through cellular communication module and sends early warning information to the basic station to still pass through satellite communication module and send early warning information to north fight satellite, and the mode of short message communication is adopted with big dipper satellite to the equipment that early warning platform corresponds moreover. Therefore, the early warning information is sent through the double links, the situation that a single link fails or the information transmission delay is large can be effectively avoided, and the effectiveness of collision early warning is improved.
According to the scheme, the early warning platform can position the vehicle by using the Beidou satellite and communicate with the vehicle, and further information reported by a plurality of vehicles is integrated, so that the early warning platform can combine the vehicle information of the target vehicle and the adjacent vehicles related to the target vehicle, and judge whether the collision risk exists between the target vehicle and the adjacent vehicles, and timely feed back early warning information to the vehicle-mounted terminal when the collision risk exists, and further the vehicle-mounted terminal can output corresponding warning signals, so that a driver can adjust the speed and the distance of the vehicle, and collision risk is avoided.
In some embodiments, for selecting a neighboring vehicle for a target vehicle by the early warning platform, an embodiment of the present application provides a solution as shown in fig. 3, fig. 3 is a flowchart of steps for determining a neighboring vehicle according to an embodiment of the present application, and as shown in the drawing, the traffic early warning method of the present application further includes the following steps:
step S310, determining the current road section of the target vehicle according to the positioning information.
Step S320, determining road section vehicles belonging to the same road section according to the positioning information of other vehicles.
Step S330, selecting vehicles in the target range of the target vehicle from the road vehicles as neighboring vehicles.
It can be understood that the vehicle information reported by the target vehicle includes positioning information, and the early warning platform can determine the specific position of the target vehicle based on the positioning information, and further can determine the road section where the target vehicle is located by combining with map road network information. Similarly, for other vehicles, the warning platform can determine the vehicle on the road section according to the positioning information, namely, select the road section vehicle which belongs to the same road section as the target vehicle.
After the road segment vehicles are selected, the early warning platform can select adjacent vehicles from the road segment vehicles, such as combining the positioning information of the target vehicle and the positioning information of each road segment vehicle, so as to determine the road segment vehicles in the target range centering on the target vehicle, and take the road segment vehicles as the adjacent vehicles.
For example, for a one-way two-lane road a, the vehicles traveling on it belong to the same road segment, i.e. belong to the same road a. Correspondingly, the early warning platform selects an adjacent vehicle for the target vehicle according to the position of the target vehicle and the size of the target range.
Thus, it is conceivable that the neighboring vehicles within the target range may be changed during the movement of the target vehicle, that is, there may be cases where a part of the vehicles no longer belong to the neighboring vehicles or a part of the vehicles become new neighboring vehicles, or the like.
Fig. 4 is a flowchart of steps for determining whether there is a collision risk according to an embodiment of the present application, where as shown in the fig. 4, the traffic early warning method of the present application further includes the following steps:
step S410, determining a first driving direction of the target vehicle and a second driving direction of the adjacent vehicle according to the heading angle of the target vehicle and the heading angle of the adjacent vehicle.
Step S420, when the first running direction and the second running direction are intersected, the safe distance between the target vehicle and the adjacent vehicle is determined according to the speed of the target vehicle and the speed of the adjacent vehicle.
Step S430, if the current distance between the target vehicle and the adjacent vehicle is smaller than the safety distance, determining that the target vehicle has collision risk.
It can be understood that the vehicle information reported by each vehicle includes the current speed and heading angle of the vehicle, and the heading angle is an included angle between the running direction of the vehicle and the longitudinal axis of the vehicle, so that the early warning platform can determine the running direction of each vehicle on each road section. It is conceivable that the traveling direction of the vehicle is changed, and therefore, the early warning platform can also update the recorded traveling direction of the vehicle according to the vehicle information continuously reported by the vehicle-mounted terminal. Of course, in the case that there is a collision risk of the vehicles, the traveling directions of the two vehicles intersect, so that when it is determined that the target vehicle intersects with one neighboring vehicle in the traveling direction, the early warning platform determines the safety distance between the two vehicles according to the speeds of the two vehicles.
For example, for a target vehicle and an adjacent vehicle traveling in opposite directions, the safe distance is the sum of the braking distances of the two vehicles. For the target vehicle and the adjacent vehicle which run in the same phase, the target vehicle is represented by A, the adjacent vehicle is represented by B, O is the intersection point of the two running directions, and when the target vehicle is represented by the speed V A Travel distance OA for a predetermined time t, and speed V of the adjacent vehicle B The travel route OB is also carried out within the preset time t, and the vehicle distance AB at the moment is taken as a safety distance. Thus, it is conceivable that the target vehicle is determined to have a collision risk when the current vehicle distance from the neighboring vehicle is smaller than the safe distance.
The scheme can judge whether the current car distance meets the requirement of the safety distance through the course angle and the car speed, further judges whether collision risk exists, is simple, convenient and quick, and can timely feed back early warning signals to the vehicle-mounted terminal, and further plays a role in informing a driver.
