It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

It should be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It should also be understood that the term "and/or" as used in this specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

In addition, in the description of the present application and the appended claims, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.

Reference in the specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments" unless expressly specified otherwise.

The existing transportation system requires a long time for providing service information to the vehicle, whether in a CPC card mode or an OBU and RSU communication mode. For example, when the existing OBU provides service information for an OBU corresponding to a vehicle based on communication between the OBU and the RSU, because different RSUs need to acquire information of the OBU corresponding to the vehicle when the vehicle passes, the OBU can be authenticated to provide service information for the OBU. Since each RSU needs a certain period of time to acquire and verify the information of the OBU, the determination of what service information is provided for the OBU is long.

Along with the construction climax of a new foundation, the informatization, networking and intelligent construction of the expressway are continuously mature in the future. Whether governments, businesses, investors, or centers and places, have developed a high-speed consensus for the construction of wisdom. Many provinces have begun to build intelligent at high speed.

Currently, the OBU is already installed on vehicles in a popular way, the OBU is installed on vehicles before leaving the factory in the future, and the capability of the vehicles for receiving the expressway road side service is gradually provided.

In the future, the expressway can provide corresponding informationized and intelligent services for vehicles, and vehicles can go out on the expressway more safely, efficiently and rapidly.

From a commercially operational perspective, if highway owners are paid-free to serve owners, the huge investment of the high-speed 'new infrastructure' cannot be recovered, which is unfavorable for the long-term healthy development of the industry.

If all the services are packed together to provide the services for the vehicle, the scheme of charging the unified price is also problematic, because different owners have different requirements, some owners do not want to charge the services, and the service charge provided for the automatic driving vehicle may be higher, and the service cannot be priced and unified.

Considering the inconsistent intelligent high-speed construction schemes of various provinces and cities, the service provided for the owners of the vehicles also has differences.

In the future, when a vehicle is traveling fast on an expressway, frequent switching between different roadside apparatuses is required. However, due to the closure of the highway, after the OBU accesses a certain roadside device, we can speculate that after a certain time, the OBU may access another (or some number of) certain known roadside devices.

If each roadside device needs to authenticate the accessed OBU, analyze and match the authentication, some problems exist:

first, system resources are wasted too much; the road side equipment always needs to reserve certain resources to cope with a large number of OBU access requests which possibly arrive;

secondly, the interaction method flow between the systems is too complicated; when the OBU moves across owners, across groups and across provinces, the service subscription condition is very complex to analyze;

third, and most importantly, the real-time nature of the service is affected. For an automatic driving vehicle, real-time performance is crucial, access authentication and subscription service analysis are frequently carried out, and real-time interaction between the vehicles and the roads is not facilitated.

In order to solve the above technical problems, an embodiment of the present application provides an intelligent transportation control system, including a roadside intelligent station (Intelligent TransportationSystem Station, ITSStation), an adapter point (ITS Transfer Point, ITP) and a cloud control Platform (ITS Platform), wherein one cloud control Platform includes at least 2 adapter points, and the jurisdiction of one adapter point includes at least 2 roadside intelligent stations. Each road side intelligent station only has a direct communication interface with the corresponding switching point, has no direct communication interface with other switching points, and needs to transmit information through the same switching point between the road side intelligent stations belonging to the same switching point. The above-mentioned road side intelligent station refers to a control station placed on the expressway (such as the expressway entrance, the expressway exit, or the road between the entrance and the exit), or on the bridge, and has the capabilities of sensing, communication, calculation, control and the like, and the above-mentioned switching point refers to a device or software module logically between the road side intelligent station and the cloud control platform. When a road side intelligent station arranged at an expressway entrance in a certain transfer point monitors that a vehicle enters an expressway, the road side intelligent station acquires first OBU access information of the vehicle, reports the first OBU access information to a corresponding transfer point, and then issues the first OBU access information to a first target road side intelligent station. The first target intelligent road station is an intelligent road station which the vehicle possibly passes through in the jurisdiction range of the first transfer point after passing through the first intelligent road station, namely, after the vehicle enters from the intelligent road station arranged at the expressway exit, the intelligent road station which the following vehicle possibly passes through can acquire first OBU access information corresponding to the vehicle in advance, so that the following vehicle can be conveniently and quickly provided with service information corresponding to subscription information, and the time period for providing the service information for the vehicle is greatly shortened.

The following describes a vehicle-mounted unit access method in a traffic control network according to an embodiment of the present application with reference to an embodiment.

Embodiment one:

fig. 1 shows a flowchart of a vehicle-mounted unit access method in a first traffic control network provided by an embodiment of the present application, where the vehicle-mounted unit access method is applied to a first switching point, and the first switching point is any switching point in an intelligent transportation control system, and the jurisdiction of the first switching point includes at least 2 roadside intelligent stations, which is described in detail below:

step S11, receiving first vehicle-mounted unit OBU access information, wherein the first OBU access information is information which is reported by a first road side intelligent station and is used for determining the validity of the OBU of the vehicle and subscribed service information, and the first road side intelligent station is positioned at the road side of an expressway entrance in the jurisdiction of a first transfer point.

Wherein a vehicle has a unique OBU.

In this embodiment, after a vehicle enters an entrance of a highway corresponding to a first switching point, the OBU requests access to a first road side intelligent station on a road side of the entrance of the highway, and the first road side intelligent station processes the request to obtain first OBU access information. Or after the first road side intelligent station monitors that the vehicle is driven into the expressway, the first road side intelligent station actively requests the OBU of the vehicle to acquire the first OBU access information. The first OBU access information further includes a unique identifier of the first road side intelligent station that is reported.

In some embodiments, the first OBU access information includes authentication information and subscription information of the OBU, and/or the access information of the OBU includes feedback information, where the feedback information includes validity information for indicating whether the OBU is legal, and when the validity information indicates that the OBU is legal, the feedback information further includes service information corresponding to the subscription information that may be provided to the OBU.

In some embodiments, the first wayside intelligent station comprises an RSU capable of wireless communication with the OBU.

Step S12, first OBU access information is issued to a first target intelligent road side station, wherein the first target intelligent road side station is an intelligent road side station which a vehicle may pass through in a first transfer point jurisdiction after passing through the first intelligent road side station.

Specifically, since the expressway has a sealing property, after a vehicle enters from an entrance of the expressway, the first roadside intelligent station where the vehicle is driven in can be estimated according to the advancing direction of the vehicle and the monitored first roadside intelligent station, namely, the roadside intelligent station where the vehicle is subsequently encountered is estimated.

In some embodiments, the first target intelligent road side station may be all intelligent road side stations through which the vehicle may pass, or may be some intelligent road side stations through which the vehicle may pass. For example, when there are many intelligent stations on the road side that the expressway may pass through (for example, the expressway has a plurality of exits), only the intelligent stations on the road side that the vehicle may pass through within a preset time period are used as the first target intelligent stations on the road side, so that the first target intelligent stations are ensured to be capable of acquiring service information corresponding to the vehicle in advance, and invalid issuing can be avoided. For example, as shown in fig. 2, the expressway corresponding to the first transfer point has 1 entrance-entrance a, 2 exits-exit B and exit C, the roadside intelligent stations at the entrance a are the roadside intelligent station a, the roadside intelligent stations at the exit B and the exit C are the roadside intelligent station B and the roadside intelligent station C, respectively, and there is a roadside intelligent station D between the exit B and the exit C, and after the vehicle enters the expressway from the roadside intelligent station a, the roadside intelligent stations possibly encountered by the vehicle subsequently are the roadside intelligent station B, the roadside intelligent station C and the roadside intelligent station D, respectively, at this time, the roadside intelligent stations possibly encountered by the vehicle within a preset period of time, for example, within half an hour, may be used as the first target roadside intelligent stations. Specifically, according to the speed limit of the expressway, it is estimated that the intelligent road stations to be reached by the vehicle within half an hour are the intelligent road station B and the intelligent road station D, that is, the intelligent road station B and the intelligent road station D are used as the first target intelligent road station, and then, if the vehicle meets a certain condition, for example, after the vehicle reaches the intelligent road station D, the intelligent road station C is used as the first target intelligent road station. However, if the vehicle directly exits from the roadside intelligent station B, the roadside intelligent station C is no longer used as the first target roadside intelligent station, and at this time, the first OBU access information does not need to be issued to the roadside intelligent station C, so that an invalid issuing event can be avoided.

In this embodiment of the present application, after the first switching point receives the first OBU access information corresponding to the vehicle driving into the expressway corresponding to the first switching point, the first OBU access information is issued to the first target roadside intelligent station. Because the first target roadside intelligent station is a roadside intelligent station which a vehicle possibly passes through in the jurisdiction of the first transfer point after passing through the first roadside intelligent station, after the first OBU access information is issued to the first target roadside intelligent station, the roadside intelligent station which the vehicle possibly passes through subsequently can acquire the first OBU access information in advance, and meanwhile, the first OBU access information is service information which is reported by the first roadside intelligent station and is used for determining the validity and subscription of the OBU of the vehicle, namely, the roadside intelligent station which the vehicle possibly passes through subsequently can determine the validity and subscription of the OBU of the vehicle through the first OBU access information which is acquired in advance, so that the vehicle is provided with service information corresponding to subscription information quickly.

In some embodiments, the first OBU access information includes authentication information and subscription information of the OBU, and/or the access information of the OBU includes feedback information, where the feedback information includes validity information for indicating whether the OBU is legal, and when the validity information indicates that the OBU is legal, the feedback information further includes service information corresponding to the subscription information, which may be provided to the OBU.

The authentication information of the OBU is used for performing identity verification on the OBU, or is used for performing identity verification and validity verification on the OBU. The identity verification of the OBU may be achieved by verifying the identity of the OBU, and the validity verification of the OBU may determine that the OBU is a legal OBU after verifying the identity of the OBU, or, in combination with other processing steps, determine whether the OBU with the identity verified is a legal OBU.

Wherein the subscription information is a service subset selected individually on the basis of the whole set of the value added services of the OBU available to the intelligent transportation control system, the subscription information comprises an identifier (Identity document, ID) of the issuing place of the OBU, and the ID of the issuing place of one OBU is used for uniquely identifying the issuing place of one OBU, and the issuing place of the OBU mainly refers to the place of the OBU subscribing to the service. That is, in the embodiment of the present application, subscription information of different OBUs may be different, so as to provide differentiated services for vehicle owners, and improve good experience of vehicle owners.

The validity information may be "yes" and "no", and when the validity information is "yes", it indicates that the OBU is a legal OBU, and when the validity information is "no", it indicates that the OBU is an illegal OBU.

In some embodiments, when the validity information indicates that the OBU is an illegal OBU, the feedback information does not include service information corresponding to subscription information that may be provided to the OBU. Therefore, information which needs to be issued to the first target roadside intelligent station in the follow-up process is reduced, and system resources are saved.

Fig. 3 shows a flowchart of a vehicle-mounted unit access method in a second traffic control network provided by the embodiment of the present application, in this embodiment, step S32 and step S33 are further described in step S12 assuming that the first OBU access information only includes authentication information and subscription information of an OBU, and step S31 is the same as step S11 and will not be repeated here.

Step S31, receiving first vehicle-mounted unit OBU access information, wherein the first OBU access information is information which is reported by a first road side intelligent station and is used for determining the validity of the OBU of the vehicle and subscribed service information, and the first road side intelligent station is positioned at the road side of an expressway entrance in the jurisdiction of a first transfer point.

In step S32, if the first OBU access information includes only authentication information and subscription information of the OBU, the feedback information is determined according to the authentication information and subscription information.

Specifically, step S32 includes:

A1, if the first OBU access information only comprises the authentication information and the subscription information of the OBU, verifying whether the OBU is legal or not according to the authentication information of the OBU, and if the OBU is legal, analyzing service information which can be provided for the OBU from the subscription information.

In some embodiments, the OBU and the first transfer point both store the same key file, and after both encrypt the same random number, the validity of the OBU is determined by verifying whether the random numbers encrypted by both sides are identical, where the authentication information of the OBU is the encrypted random number. In some embodiments, if authentication is achieved by sending CA (Certification Authority) certificate, the authentication information of the OBU at this time is the CA certificate.

In some embodiments, if the OBU is not a legitimate OBU, the subscription information is not parsed. Since the analysis steps are reduced, the time period required to draw a conclusion on whether to provide service information for the OBU is shortened.

A2, determining feedback information, wherein the feedback information comprises validity information for indicating whether the OBU is legal or not, and when the validity information indicates that the OBU is legal, the feedback information further comprises service information which can be provided for the OBU and corresponds to subscription information.

In the above-mentioned A1 and A2, whether the OBU is legal is verified according to the authentication information of the OBU, and the subscription information is parsed only after the OBU is verified to be legal, so that the system resource is effectively saved, and the time period required for obtaining the conclusion of whether the OBU provides service information is shortened.

In some embodiments, in step A1, when service information that can be provided to the OBU is parsed from the subscription information, the method specifically includes:

a11, analyzing the identification of the issuing place of the OBU from the subscription information.

And A12, if the service list corresponding to the identifier of the issuing place is the service list of the first transfer point, taking the service information in the service list of the first transfer point as the service information which can be provided to the OBU.

Specifically, the service list corresponding to the first cloud control platform is a service list of each transfer point under the first cloud control platform. In this embodiment, there is a one-to-one correspondence between the cloud control platform and the identifier of the issuing location of the OBU, and when the identifier of the issuing location of the OBU and the first cloud control platform are in a one-to-one correspondence, the service list corresponding to the identifier of the issuing location of the OBU is the service list of the first transfer point. Each service list stores corresponding service information, which may include group fog pre-warning, congestion pre-warning, accident pre-warning, etc.

And A13, if the service list corresponding to the identifier of the issuing place is not the service list of the first transfer point, sending a service list acquisition request to the first cloud control platform corresponding to the first transfer point, wherein the service list acquisition request carries the identifier of the issuing place, and the service list acquisition request is used for indicating the first cloud control platform to acquire the service list of the cloud control platform corresponding to the identifier of the issuing place.

In this embodiment, when the service list of the first switching point is not the service list corresponding to the identifier of the issuing location of the OBU, it indicates that the OBU does not subscribe to local service information, at this time, the first switching point sends a service list acquisition request to the first cloud control platform, and the first cloud control platform determines the corresponding cloud control platform according to the identifier of the issuing location of the OBU, and if the first cloud control platform is assumed to be the second cloud control platform, the first cloud control platform acquires the service list corresponding to the second cloud control platform again.

And A14, receiving a service list of the cloud control platform corresponding to the identification of the issuing place, which is sent by the first cloud control platform, and taking service information in the service list of the cloud control platform corresponding to the identification of the issuing place as service information which can be provided for the OBU.

Specifically, the first transfer point receives a service list of a second cloud control platform (the second cloud control platform is a cloud control platform corresponding to an identifier of an issuing place of the OBU) sent by the first cloud control platform, and takes service information in the service list of the second cloud control platform as service information which can be provided for the OBU, that is, the OBU subscribes to relevant service information in the second cloud control platform.

In the above-mentioned a 11-a 14, after resolving the identifier of the issuing place of the OBU from the subscription information, determining the service information subscribed by the OBU in the corresponding cloud control platform by combining with the identifier of the issuing place of the OBU, and returning to the OBU. The service information subscribed by the OBU on different cloud control platforms can be determined, so that the corresponding service information can be returned to the OBU quickly, the time for acquiring the service information can be shortened, and the corresponding service information can be provided for the OBU quickly.

And step S33, the feedback information is issued to the first target road side intelligent station.

In the embodiment of the application, since the corresponding feedback information is determined according to the authentication information and the subscription information of the OBU only included in the first OBU access information, and the feedback information is issued to the first target roadside intelligent station, and the feedback information includes the legality information for indicating whether the OBU is legal, and when the legality information indicates that the OBU is legal, the feedback information further includes the service information corresponding to the subscription information which can be provided to the OBU, the first target roadside intelligent station can directly judge whether the corresponding OBU is legal or not according to the feedback information, and provide what kind of service to the legal OBU, thereby greatly reducing the operation amount of the first target roadside intelligent station and improving the speed of the first target roadside intelligent station for providing service to the vehicle.

In some embodiments, the first switching point may also send the authentication information, the subscription information, and the feedback information of the OBU to the first target roadside intelligent station at the same time, where step S33 specifically includes: and sending feedback information, authentication and authorization information of the OBU and subscription information to the first target road side intelligent station.

Fig. 4 shows a flowchart of a third vehicle-mounted unit access method in a traffic control network according to the embodiment of the present application, in this embodiment, step S42 is further described in step S12 assuming that the first OBU access information includes feedback information, and step S41 is the same as step S11, which is not repeated here.

Step S41, receiving first vehicle-mounted unit OBU access information, wherein the first OBU access information is information which is reported by a first road side intelligent station and is used for determining the validity of the OBU of the vehicle and subscribed service information, and the first road side intelligent station is positioned at the road side of an expressway entrance in the jurisdiction of a first transfer point.

And step S42, if the first OBU access information comprises feedback information, the feedback information is issued to the first target roadside intelligent station.

The first OBU access information herein includes feedback information, which means that the first OBU access information only includes feedback information, or may also mean that the first OBU access information includes feedback information, authentication information of the OBU, and subscription information.

In the embodiment of the application, since the first OBU access information received by the first switching point includes the feedback information, the first switching point does not need to determine the corresponding feedback information from the authentication and authorization information and the subscription information of the OBU, thereby saving the calculation amount of the first switching point.

In some embodiments, the method for accessing an on-board unit in a traffic control network further comprises:

and sending feedback information to the first road side intelligent station.

In this embodiment, the first switching point issues the obtained feedback information to the first intelligent station on the way, for example, when the first intelligent station on the way does not have the capability of calculating the corresponding feedback information according to the authentication and authorization information and the subscription information of the OBU, the first intelligent station on the way issues the corresponding feedback information to the first intelligent station on the way, so that the first intelligent station on the way can determine whether to provide the service corresponding to the subscription information to the OBU according to the feedback information.

Fig. 5 shows a flowchart of a vehicle-mounted unit access method in a fourth traffic control network according to an embodiment of the present application, where in this embodiment, a vehicle enters and exits on an expressway at a first switching point, and a first target roadside intelligent station includes a second roadside intelligent station, and the second roadside intelligent station is located on a roadside of an expressway exit in a jurisdiction of the first switching point, that is, the roadside intelligent station corresponding to each exit of the expressway in the jurisdiction of the first switching point may be referred to as a second roadside intelligent station. Step S51 and step S52 are the same as step S11 and step S12 described above, and will not be described here again.

Step S51, receiving first on-board unit OBU access information, where the first OBU access information is information reported by a first road side intelligent station, where the first road side intelligent station is located on a road side of an expressway entrance in a jurisdiction of a first transfer point, and the information is used to determine validity of an OBU of a vehicle and subscribed service information.

Step S52, issuing first OBU access information to a first target intelligent roadside station, where the first target intelligent roadside station is an intelligent roadside station through which the vehicle may pass in the jurisdiction of the first transfer point after passing through the first intelligent roadside station.

Step S53, if the exit information of the vehicle exiting the expressway reported by the second road side intelligent station is received, a first access removing instruction is sent to the first target road side intelligent station and the first road side intelligent station, where the exit information includes an identifier of an OBU corresponding to the vehicle, and the first access removing instruction is used to instruct the first target road side intelligent station and the first road side intelligent station to delete authentication information, subscription information and feedback information of the OBU corresponding to the identifier of the OBU.

Specifically, if the first target roadside intelligent station or the first roadside intelligent station does not include any one of the authentication information, the subscription information, and the feedback information of the OBU, the corresponding deletion action does not need to be performed. Only the first target road side intelligent station and the first road side intelligent station are required to be ensured to have no authentication information, subscription information and feedback information of the OBU.

It should be noted that, when the second roadside intelligent station is located at the roadside of the exit of the expressway corresponding to the first transfer point, and the second roadside intelligent station monitors that the vehicle exits the expressway, the second roadside intelligent station is necessarily a roadside intelligent station through which the vehicle may subsequently pass after entering the expressway from the first roadside intelligent station, that is, the second roadside intelligent station is a first target roadside intelligent station, that is, the second roadside intelligent station necessarily receives the first OBU access information, so the second roadside intelligent station also needs to delete the authentication information, the subscription information and the feedback information of the OBU corresponding to the OBU. In addition, since the first OBU access information is reported by the first intelligent station on the first road side, the first intelligent station on the first road side must also include the first OBU access information, so the first switching point needs to instruct the first intelligent station on the first road side to also delete the authentication information, subscription information and feedback information of the OBU.

In this embodiment of the present application, after a vehicle exits from a highway, authentication information, subscription information, and feedback information of an OBU corresponding to the first target roadside intelligent station and the first roadside intelligent station are cleared, that is, authorization for pre-accessing the OBU at this time is deleted, so that the first target roadside intelligent station and the first roadside intelligent station can be prevented from abnormal service caused by changes in subscription service or validity of the OBU when the first target roadside intelligent station and the first roadside intelligent station provide services for the OBU next time.

Fig. 6 shows a flowchart of a fifth method for accessing a vehicle-mounted unit in a traffic control network according to an embodiment of the present application, where in this embodiment, a vehicle runs on a highway corresponding to different switching points, and steps S61 to S62 are the same as steps S11 to S12, and are not repeated here:

step S61, receiving first on-board unit OBU access information, where the first OBU access information is information reported by a first road side intelligent station, where the first road side intelligent station is located on a road side of an expressway entrance in a jurisdiction of a first transfer point, and the information is used to determine validity of an OBU of a vehicle and subscribed service information.

Step S62, the first OBU access information is issued to the first target intelligent road side station, wherein the first target intelligent road side station is an intelligent road side station which the vehicle may pass through in the jurisdiction of the first transfer point after passing through the first intelligent road side station.

Step S63, if second OBU access information is received, the second OBU access information is sent to the second switching point, where the second OBU access information is information reported by a third-way side intelligent station and used for determining validity of an OBU of the vehicle and subscribed service information, the third-way side intelligent station is located on a road side of an expressway exit in a jurisdiction range of the first switching point and is located at a junction of the first switching point and the jurisdiction range of the second switching point, each road side intelligent station in the jurisdiction range of the second switching point is different from each road side intelligent station in the jurisdiction range of the first switching point, and the first OBU access information is used for indicating the second switching point to issue the first OBU access information to a second target road side intelligent station, which is a road side intelligent station in the jurisdiction range of the second switching point.

Specifically, if the third-way intelligent station located at the exit of the expressway in the jurisdiction of the first switching point and located at the road side bordering the jurisdiction of the second switching point only monitors that the vehicle is driving into the expressway, but does not monitor that the vehicle is driving out of the expressway, the third-way intelligent station reports the acquired access information of the OBU of the vehicle, that is, the second OBU access information (the second OBU access information is the service information for determining the validity and subscription of the OBU of the vehicle, reported by the third-way intelligent station) to the first switching point, the first switching point judges that the access information is the same, and the second switching point sends the acquired second OBU access information to the road side intelligent station in the jurisdiction of the second switching point, so that the road side intelligent station in the jurisdiction of the second switching point can also rapidly provide services for the corresponding OBU according to the second OBU access information.

In some embodiments, the second transfer point only issues the second OBU access information to the roadside intelligent station through which the vehicle may pass from the first transfer point to the second transfer point, so as to save system resources that are consumed for the issuing.

In this embodiment of the present application, since the first transfer point may still be capable of sending the second OBU access information to the second transfer point in advance when the vehicle travels across the transfer points, so that the second transfer point may be capable of acquiring service information subscribed by the vehicle in advance, thereby being capable of providing corresponding services for the vehicle in time. In addition, when the OBU moves across the transfer points, if the pre-access of the OBU is not performed on the road side intelligent station in the corresponding transfer point, interaction is required to be performed on the upper layer across the cloud control platforms, and interaction across the cloud control platforms is very slow, but after the transfer points are introduced, the transfer points between different cloud control platforms can be directly connected, so that the transfer of the OBU related information can be performed, thereby realizing the switching of the OBU of different cloud control platforms, different transfer points and different road side intelligent stations, and complex request and interaction are not required to be performed between the cloud control platforms after the transfer points are introduced, so that the interaction cost is reduced.

Fig. 7 shows a flowchart of a method for accessing a vehicle-mounted unit in a sixth traffic control network according to the embodiment of the present application, in this embodiment, a vehicle runs on a highway corresponding to different switching points, where steps S71 to S73 are the same as steps S61 to S63, and are not repeated here:

in step S71, first on-board unit OBU access information is received, where the first OBU access information is information reported by a first on-board intelligent station, and is used to determine validity of an OBU of a vehicle and subscribed service information, and the first on-board intelligent station is located on a road side of an expressway entrance in a jurisdiction of a first transfer point.

Step S72, the first OBU access information is issued to the first target intelligent station, where the first target intelligent station is an intelligent station that may pass through in the jurisdiction of the first transfer point after the vehicle passes through the first intelligent station.

Step S73, if second OBU access information is received, the second OBU access information is sent to the second switching point, where the second OBU access information is information reported by a third-way side intelligent station and used for determining validity of an OBU of the vehicle and subscribed service information, the third-way side intelligent station is located on a road side of an expressway exit in a jurisdiction range of the first switching point and is located at a junction between the first switching point and the jurisdiction range of the second switching point, each road side intelligent station in the jurisdiction range of the second switching point is different from each road side intelligent station in the jurisdiction range of the first switching point, and the first OBU access information is used for indicating the second switching point to issue the first OBU access information to a second target road side intelligent station, which is a road side intelligent station in the jurisdiction range of the second switching point.

Step S74, if a second access removing instruction sent by the second switching point is received, the second access removing instruction is sent to the first target intelligent station and the first intelligent station, where the second access removing instruction carries an OBU identifier, and the second access removing instruction is used to instruct the first target intelligent station and the first intelligent station to delete the authentication information, subscription information and feedback information of the OBU corresponding to the OBU identifier.

Specifically, if a vehicle enters an expressway in the jurisdiction of the second switching point from an expressway in the jurisdiction of the first switching point, after the vehicle is monitored to exit the expressway in the jurisdiction of the certain switching point, the certain switching point sends a second access instruction to each switching point corresponding to the expressway on which the vehicle has previously traveled. For example, assuming that the vehicle, after entering from the first transfer point, passes through the second transfer point and finally exits the highway under the jurisdiction of the third transfer point, the third transfer point sends a second access-removing instruction to the second transfer point, which in turn sends the second access-removing instruction to the first transfer point. And each transfer point issues a second access removing instruction to the corresponding intelligent road side station, so that the intelligent road side station in the first transfer point, the second transfer point and the third transfer point delete the authentication information, subscription information and feedback information of the OBU corresponding to the vehicle.

In the embodiment of the application, the authentication and authorization information, the subscription information and the feedback information of the OBU corresponding to the OBU which has exited the expressway and stored in different switching points are timely cleared, so that the abnormality caused when the OBU is provided with service in the follow-up process can be avoided.

In order to more clearly describe the vehicle unit access method provided in the embodiment of the present application, the following description is made with reference to fig. 8.

In fig. 8, the entrance and exit of the vehicle are both in the jurisdiction of the first ITP, the first is Station where the entrance of the vehicle is monitored, the second is Station where the exit of the vehicle is monitored, and the intermediate is Station between the first and second stations, which may be greater than 1.

After the first ITS Station monitors that the vehicle enters the expressway, the first ITP reports first OBU access information to the corresponding first ITP, the first ITP judges that the intermediate ITS Station and the second ITS Station are ITS stations through which the vehicle possibly passes, and then the first ITS Station sends the first OBU access information to the intermediate ITS Station, the second ITS Station and the first ITS Station (of course, according to the description, the information sent to the first ITS Station can be feedback information), and each ITS Station receiving the first OBU access information judges whether to provide corresponding services for the vehicle.

After the second ITS Station monitors that the vehicle exits the expressway, the exiting information of the vehicle is reported to the corresponding first ITP, and the first ITP issues a first access instruction to each ITS Station which issues the first OBU access information before, so that each corresponding ITS Station deletes the authentication information, subscription information and feedback information of the OBU corresponding to the vehicle.

It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic of each process, and should not limit the implementation process of the embodiment of the present application in any way.

Embodiment two:

fig. 9 shows a flowchart of an on-board unit access method in a traffic control network provided by the embodiment of the present application, where the on-board unit access method is applied to a roadside intelligent station, and the roadside intelligent station includes a first target roadside intelligent station and a first target roadside intelligent station, where the first roadside intelligent station is located on a roadside of an expressway entrance in a jurisdiction of a first transfer point, and the first target roadside intelligent station is a roadside intelligent station that a vehicle may pass through in the jurisdiction of the first transfer point after passing through the first roadside intelligent station, where the details are as follows:

In step S91, the first road side intelligent station obtains an access request sent by an OBU of a vehicle entering the expressway, where the access request includes authentication information and subscription information of the OBU.

Specifically, after the vehicle enters the expressway, an access request is sent to the first road side intelligent station. In some embodiments, the first wayside intelligent station comprises an RSU capable of wireless communication with the OBU.

In step S92, the first road side intelligent station determines first OBU access information according to the authentication and authorization information and subscription information of the OBU, where the first OBU access information is information for determining validity of the OBU and subscribed service information.

The authentication and subscription information of the OBU are the same as those of the first embodiment, and are not described herein.

Specifically, after the first road side intelligent station analyzes the access request, the authentication and authorization information and subscription information of the OBU are used as first OBU access information. Or after the first road side intelligent station processes the authentication information and the subscription information of the OBU, the processed information is used as first OBU access information.

And step S93, the first road side intelligent station reports the first OBU access information to the first transfer point.

In some embodiments, the first roadside intelligent station performs preliminary verification on the OBU, and reports the first OBU access information to the first transfer point if the preliminary verification is passed, or does not report the first OBU access information to the first transfer point. By the processing, when the OBU is illegal, system resources occupied by reporting the first OBU access information corresponding to the illegal OBU can be reduced.

In step S94, the first target roadside intelligent station receives the first OBU access information sent by the first transfer point, and selects whether to provide service information corresponding to the subscription information to the OBU according to the first OBU access information.

In this embodiment, if it is determined that the OBU is legal according to the first OBU access information and it is determined that the service information subscribed by the OBU, the first target roadside intelligent station provides service information corresponding to the subscription information to the OBU, otherwise, does not provide service information corresponding to the subscription information to the OBU. In some embodiments, the first roadside intelligent station also receives the first OBU access information issued by the first transfer point, and selects whether to provide service information corresponding to the subscription information to the OBU according to the first OBU access information.

In this embodiment of the present application, since the first target roadside intelligent station may obtain, in advance, the first OBU access information corresponding to the OBU that enters the vehicle, so it may determine, in advance, the service subscribed to by the vehicle, and further may provide, in time, corresponding service information for the vehicle when the vehicle passes through.

In some embodiments, step S92 includes:

b1, the first road side intelligent station verifies whether the OBU is legal according to the authentication information of the OBU, and if the OBU is legal, service information which can be provided for the OBU is analyzed from the subscription information.

B2, the first road side intelligent station determines feedback information, wherein the feedback information comprises validity information for indicating whether the OBU is legal or not, and when the validity information indicates that the OBU is legal, the feedback information further comprises service information which can be provided for the OBU and corresponds to subscription information.

Authentication and authorization information and subscription information of the OBU, and/or feedback information is used as first OBU access information.

In the above B1 and B2, the process of determining the service information by the first intelligent station at the road side is similar to the process of determining the service information by the first switching point, and will not be described herein. Through the processing, the first road side intelligent station can quickly acquire the corresponding first OBU access information, and further can quickly judge whether corresponding service information needs to be provided for the vehicle.

In some embodiments, the first target roadside intelligent station comprises a second roadside intelligent station located on a roadside of the highway exit in the jurisdiction of the first transfer point, and the on-board unit access method further comprises:

and C1, if the second road side intelligent station monitors that the vehicle exits the expressway, the second road side intelligent station sends a first access removing request to the first transfer point, wherein the first access removing request carries the exit information of the vehicle exiting the expressway, which is monitored by the second road side intelligent station, and the exit information comprises the identification of the OBU corresponding to the vehicle.

The driving-out information may also include the time, place, etc. of the vehicle driving out.

Specifically, after the first switching point receives the first access removing request, a first access removing instruction is determined according to the first access removing request, and then the first access removing instruction is issued to each intelligent road side station through which the vehicle passes. Wherein the first de-access instruction includes an identification of the OBU.

And C2, the first target road side intelligent station and the first road side intelligent station receive a first access removing instruction sent by the first transfer point, wherein the first access removing instruction is used for indicating the first target road side intelligent station and the first road side intelligent station to delete the authentication information, subscription information and feedback information of the OBU corresponding to the identification of the OBU.

In the above C1 and C2, since the first target roadside intelligent station and the first roadside intelligent station each delete the authentication information, the subscription information and the feedback information of the OBU corresponding to the identifier of the OBU, the anomaly possibly caused by providing the service information for the same OBU in the following process can be avoided.

In some embodiments, the roadside intelligent station further comprises a third roadside intelligent station located on a roadside of the highway exit within the jurisdiction of the first transfer point and located at a junction of the jurisdiction of the first transfer point and a second transfer point, each of the roadside intelligent stations within the jurisdiction of the second transfer point being different from each of the roadside intelligent stations within the jurisdiction of the first transfer point, the on-board unit access method further comprising:

If the OBU of the vehicle is accessed to the third-path side intelligent station, and the third-path side intelligent station does not monitor that the vehicle exits the expressway, the third-path side intelligent station reports second OBU access information to the first switching point, wherein the second OBU access information is used for indicating the first switching point to send the second OBU access information to the second switching point, and is used for indicating the second switching point to send the second OBU access information to the road side intelligent station in the jurisdiction of the second switching point.

In this embodiment, when the vehicle passes by a third-path side intelligent station adjacent to the first switching point and the second switching point, but does not exit the expressway, the third-path side intelligent station reports the second OBU access information corresponding to the OBU to the first switching point corresponding to the third-path side intelligent station. The second OBU access information is information which is reported by the third-path intelligent station and used for determining the legitimacy of the OBU of the vehicle and subscribed service information. In addition, the second OBU access information also carries the identification of the third-path side intelligent station and the information that the vehicle does not leave the expressway. The first transfer point judges that the vehicle enters the road side intelligent station in the jurisdiction of the second transfer point according to the identification of the third road side intelligent station carried by the second OBU access information and the information that the vehicle does not leave the expressway, and the first transfer point does not need to send the second OBU access information to other road side intelligent stations in the jurisdiction of the second transfer point, but needs to send the second OBU access information to an adjacent second transfer point, and the second transfer point sends the second OBU access information to a second target road side intelligent station, wherein the second target road side intelligent station is the road side intelligent station in the jurisdiction of the second transfer point, so that the second target road side intelligent station can acquire relevant information of service information subscribed by the OBU in advance, and further provide corresponding service information for the OBU in time.

In some embodiments, the intelligent roadside station further comprises a fourth intelligent roadside station located on a roadside of the highway exit within the jurisdiction of the second transit point,

if the fourth road side intelligent station monitors that the vehicle exits the expressway, the exit information of the vehicle is reported to the second switching point, the exit information is used for indicating the second switching point to send a second access removing instruction to the first switching point, the second access removing instruction carries an OBU identifier, and the second access removing instruction is used for indicating the first target road side intelligent station and the first road side intelligent station to delete the authentication information, subscription information and feedback information of the OBU corresponding to the OBU identifier.

In this embodiment, since the vehicle enters the expressway at the first transfer point, but after the second transfer point exits the expressway, the second transfer point also sends the second access removing instruction to the first transfer point, so that the first transfer point can notify the first target roadside intelligent station and the first roadside intelligent station to delete the authentication information, subscription information and feedback information of the OBU corresponding to the vehicle, thereby avoiding possible abnormality when the first target roadside intelligent station and the first roadside intelligent station subsequently provide service information for the OBU again. Of course, after the second switching point receives the second access removing instruction, the second switching point further sends the second access removing instruction to the second target roadside intelligent station in the jurisdiction of the second switching point, so that the second target roadside intelligent station deletes the authentication and authorization information, subscription information and feedback information of the OBU corresponding to the vehicle.
