Description

Priority passing method and system based on Internet of vehicles

Technical Field

The invention belongs to the technical field of vehicle passing control, and particularly relates to a priority passing method and system based on a vehicle networking.

Background

A one-way lane is a lane that allows travel in only one direction. One-way traffic is widely adopted in western developed countries as a traffic management measure with less investment, quick response and simple and convenient operation. In recent years, many cities in China also actively adopt one-way traffic, and part of two-way roads are directly changed into one-way roads, so that the traffic pressure of the roads is relieved to a great extent, and the congestion situation is reduced. The one-way road is the most direct, effective and economical method for solving the urban traffic jam and increasing the traffic capacity, and the global smoothness is guaranteed by local limitation.

Things always have their own benefits while they have their own disadvantages. For example, if the destination to be reached is opposite to the direction allowed for a one-way road, the vehicle may need to detour around other roads that are relatively far away, which may cause some inconvenience to the vehicle. For ordinary social vehicles, time and energy consumption costs are more acceptable, but certain influence is caused on the actions of special vehicles (such as ambulances, fire trucks, police cars, engineering emergency vehicles and the like) which have to compete for minutes in task execution. Although the special vehicle for executing the task can move backwards on the one-way road without being limited by the driving speed, the driving route, the driving direction and the signal of the command lamp under the condition of ensuring the safety according to the relevant regulations, the special vehicle for executing the task does not have a good communication and coordination mechanism between the current vehicles and the road, other vehicles, pedestrians and other traffic participants, and the like, so that the special vehicle for executing the task can move backwards on the one-way road to easily cause traffic jam and/or accidents. How to realize safe and rapid retrograde motion of special vehicles executing tasks on a one-way road under the background of great development of the current Internet of vehicles technology is a problem which needs to be solved urgently. .

The specific implementation mode is as follows:

in order to make the objects, technical solutions and advantages of the present invention clearer and more obvious, the present invention is further described in detail below with reference to the accompanying drawings and technical solutions.

The embodiment of the scheme provides a priority passing method based on an internet of vehicles, and the method is characterized in that the reverse priority passing of a single-way road of a vehicle with a specific task is realized through information interaction among a cloud server, a vehicle end and a road side end of the internet of vehicles, and the implementation process comprises the following contents:

s101, vehicle information with priority right of passage and corresponding relation between a one-way road and a roadside end are stored in a cloud server in an internet of vehicles in advance, and a one-way road sign containing a digital watermark is preset on the one-way road, wherein the digital watermark comprises a one-way road digital abstract, a one-way road installation position and a digital signature containing the digital abstract and the position, and the vehicle information comprises a vehicle number plate and/or a vehicle identification code;

s102, aiming at a priority passing request of a target vehicle, a cloud server identifies and extracts a digital signature in a to-be-used one-way road sign, verifies the passing authority of the target vehicle, and sends target vehicle information passing the passing authority verification to a road side end corresponding to the to-be-used one-way road of the target vehicle, wherein the priority passing request comprises a vehicle number plate and/or a vehicle identification code of the target vehicle and the to-be-used one-way road sign;

s103, generating priority passing instruction information used for the target vehicle to pass preferentially and prompting other vehicles and pedestrians to avoid by the roadside end of the one-way road on which the target vehicle waits to run, and enabling the target vehicle to pass through the current road section on the one-way road in a reverse direction preferentially.

Aiming at a target vehicle executing a specific task, information safety transmission in the vehicle passing process is realized by utilizing the internet of vehicles and a network technology, social vehicles and pedestrians can know the current and/or upcoming vehicle end condition through the priority passing indication information of the roadside end, and the position, direction and/or avoidance of the social vehicles and the pedestrians can be adjusted in time, so that the vehicle end can safely and smoothly realize priority passing.

As a preferred embodiment, further, for the priority pass request of the target vehicle, the cloud server identifies and extracts the digital signature in the to-be-used one-way sign, and verifies the pass authority of the target vehicle, including: and matching the license plate number and/or the vehicle identification code of the target vehicle with pre-stored vehicle information, if the relevant vehicle information is matched, acquiring a road side end and a one-way road geographical position corresponding to the one-way road sign by extracting a digital signature in the one-way road sign, calculating the distance between the geographical position of the target vehicle and the geographical position of a stop point of the one-way road to be driven, and judging that the passing authority of the target vehicle passes verification under the condition that the distance meets a preset threshold value.

The vehicle end acquires a one-way road sign image and the geographic position information of the vehicle end; sending priority passing request information to the cloud server; the priority traffic request information comprises but is not limited to vehicle end related information and the one-way road sign image; the vehicle-end related information also comprises geographic position information of the vehicle end. And after receiving the priority traffic request information, the cloud server performs image identification on the one-way road sign image, extracts a road side end number from the one-way road sign image, and then searches the geographical position information of the one-way road corresponding to the road side end according to the road side end number.

The cloud server compares the vehicle number plate information in the vehicle end related information with preset and stored vehicle number plates, and if the related vehicle number plate is not found, the cloud server directly returns a passing authority which does not allow reverse passing to the vehicle end; and if the related vehicle number plate is found, the passing permission of the vehicle end corresponding to the vehicle number plate on the one-way road is found. If the passing authority of the vehicle end does not allow reverse passing, the cloud server sends the passing authority not allowing reverse passing to the vehicle end, and the vehicle end cannot pass in the reverse direction on the one-way road after receiving the passing authority but automatically selects other roads to bypass and pass.

And if the passing authority of the vehicle end is that reverse passing is allowed, the cloud server continuously tries to identify the digital watermark contained in the image of the one-way road sign. If the digital watermark identification fails, judging that the single-lane signboard image is an illegal safe single-lane signboard image, and returning a passing right which does not allow reverse passing to the vehicle end by the cloud server; specifically, if the digital watermark information is failed to be identified, it is indicated that the image of the one-way sign does not contain the digital watermark information or the digital watermark information is damaged and cannot be identified. And if the digital watermark is successfully identified, the cloud server extracts the digital watermark information contained in the safe one-way road sign image to obtain the digital abstract of the common one-way road sign image, the position information of the target placement point of the safe one-way road sign and the digital signature information of the digital abstract and the position information. And the cloud server checks the digital signature of the digital abstract and the position information according to the digital abstract of the image of the common one-way road sign and the position information of the target placing point of the safe one-way road sign. And if the verification fails, judging that the safe one-way road sign image is an illegal safe one-way road sign image, and then returning a passing right which does not allow reverse passing to the vehicle end by the cloud server. If the signature verification is successful, judging that the safe single-lane sign image is complete and is not tampered and is a legal safe single-lane sign image issued by the cloud server; then, the cloud server calculates the distance between the geographic position of the vehicle end and the geographic position of the end point of the one-way road.

When the distance reaches or is lower than a threshold value, the cloud server sends a passing permission allowing reverse passing to the vehicle end, and the vehicle end passes through the single-way road in a reverse way under the condition of ensuring safety; the cloud server simultaneously sends the vehicle end related information to a roadside end corresponding to the one-way road, and then the roadside end controls a traffic signal controller, a priority information display board and a marking projection module according to the vehicle end related information to reflect the vehicle end related information and prompt social vehicles and pedestrians to take avoidance measures, wherein the avoidance measures comprise but are not limited to in-situ waiting, passing and/or detouring; preferably, the roadside end further controls an intelligent spike and/or a voice prompt module to reflect the vehicle end related information and prompt social vehicles and pedestrians to take avoidance measures, wherein the avoidance measures include but are not limited to waiting in place, yielding and/or detouring.

When the distance does not reach or is higher than the threshold value, the cloud server sends a requirement for continuously providing the geographic position information of the vehicle end in real time to the vehicle end; after the vehicle end receives the requirement, the geographic position of the vehicle end is continuously acquired in real time and is sent to the cloud server in real time; after receiving the geographic position information of the vehicle end, the cloud server also calculates the distance between the geographic position of the vehicle end and the geographic position of the termination point of the one-way road in real time, and the acquisition and calculation are stopped until the distance reaches or is lower than the threshold value; when the distance reaches or is lower than the threshold value, the cloud server executes the operation when the distance reaches or is lower than the threshold value, and sends the corresponding information to the vehicle end and the roadside end respectively.

The threshold value can be specified or appointed by related departments in advance and is arranged in the vehicle end; as an example, the threshold may be 200 meters, 100 meters, 50 meters, or other distance. And after receiving the passing permission which does not allow reverse passing, the vehicle end can not pass through the one-way road in the reverse direction, and automatically selects other roads to pass by.

Before the prior traffic based on the invention, a safety one-way road sign is generated, placed and installed, a related department responsible for traffic sign management can plan and design a common one-way road sign image and determine the position information of a target placing point of the safety one-way road sign, and then the common one-way road sign image and the position information of the target placing point of the safety one-way road sign are provided for the cloud server; the location information of the target placement point of the safety one-way road sign includes, but is not limited to, geographical location information of a start point and/or an end point of the one-way road.

The cloud server generates a digital abstract of a common one-way road sign image based on the common one-way road sign image, and then generates digital signature information of the digital abstract and the position information based on the digital abstract of the common one-way road sign image and the position information of the target placement point of the safety one-way road sign. And the cloud server takes the digital abstract of the ordinary one-way road sign image, the position information of the target placing point of the safety one-way road sign and the digital signature information of the digital abstract and the position information as parameters to generate digital watermark information, and then, the digital watermark information is embedded into the ordinary one-way road sign image to generate the safety one-way road sign image. And the cloud server generates the safe one-way road sign plate image into the safe one-way road sign plate according to the printing and manufacturing specifications of the one-way road sign plate.

And the related department responsible for the traffic sign management places the safety single-way road sign at a corresponding position according to the position information of the target placement point of the safety single-way road sign.

The priority passing request information sent by the vehicle end to the cloud server can also comprise time information of the vehicle end when the geographic position information of the vehicle end is collected; when a plurality of vehicle ends are provided, when the plurality of vehicle ends send priority traffic request information to be preferentially passed in the reverse direction on the one-way road to the cloud server, the cloud server can queue the priority traffic request information of the vehicle ends according to the distance between the geographical position of each vehicle end and the geographical position of the termination point of the one-way road and the time sequence relation of the time in the time information, and then the cloud server determines which vehicle end to inquire the traffic authority of the one-way road according to the sequence of the queue; the queuing of the priority traffic request information of the vehicle ends is firstly queued according to the distance between the geographical position of each vehicle end and the geographical position of the termination point of the one-way road, and the distance is arranged in front; if the distances are the same, queuing is performed according to the time of sending the request information in each vehicle end, and the time is arranged in front earlier.

The priority passing request information sent by the vehicle end to the cloud server can also comprise digital signature information of the private key of the vehicle end used by the vehicle end on the related information of the vehicle end; before the cloud server compares the vehicle number plate and/or the vehicle identification code in the vehicle-end related information contained in the priority traffic request information with the vehicle number plate and/or the vehicle identification code preset and stored in the cloud storage module, the cloud server checks the digital signature information of the vehicle-end related information by using a public key in a public key certificate of a vehicle end; and if the verification fails, directly returning the passing authority which does not allow reverse passing to the vehicle end.

Before the cloud server returns the passage authority to the vehicle end, the cloud server can utilize a private key of the cloud server to digitally sign the passage authority to generate a passage authority digital signature, and then the passage authority and the passage authority digital signature are returned to the vehicle end together; after the vehicle end receives the passage authority and the digital signature of the passage authority, the public key in the public key certificate of the cloud server is used for checking the digital signature of the passage authority; if the verification is unsuccessful, the vehicle end sends a request for regenerating and sending the pass authority and the pass authority digital signature to the cloud server; and if the signature verification is successful, the vehicle end performs corresponding operation according to the passing authority of the vehicle end.

And the cloud server can also send the vehicle-end related information to the front of a road side end corresponding to the one-way road, and the cloud server carries out digital signature on the vehicle-end related information by using a private key of the cloud server to generate a vehicle-end related information digital signature, and then sends the vehicle-end related information and the vehicle-end related information digital signature to the road side end together. After the road side end receives the vehicle side related information and the vehicle side related information digital signature, the public key in the public key certificate of the cloud server is used for verifying the vehicle side related information digital signature; if the signature verification is unsuccessful, the roadside end sends a request for regenerating and sending the vehicle-end related information and the vehicle-end related information digital signature to the cloud server; and if the signature verification is successful, the roadside end performs corresponding operation according to the vehicle end related information.

Preferably, when the vehicle end, the cloud server and the road side end send information to each other, a timestamp and a random number may be added, and corresponding verification is performed at a receiving party, so as to prevent the information from being attacked by replay.
