Referring to fig. 1, fig. 1 shows a schematic system structure diagram of a vehicle-road coordination system provided in an embodiment of the present application, as shown in fig. 1, a DRCRM may be provided in the vehicle-road coordination system, a plurality of drdrdrdrcrms may be distributed under the DRCRM, and a plurality of DRSUs may be distributed under each DRCRM.
In this embodiment, a DRSU is installed on a road at intervals, multiple DRSUs are distributed on each specific line, and the DRSUs on the same specific line are managed and controlled by one DRC, that is, all the DRSUs on each specific line are accessed to the same DRC. Therefore, the DRSU on each specific line can collect the traffic information of the specific line.
When an automatic driving vehicle provided with the ACU runs on a specific line, the ACU can access the DRC of the specific line, and after the DRC of the specific line is accessed, the ACU can receive road condition information reported by the DRSU on the specific line from the DRC, so that the automatic driving vehicle can run normally.
Each DRC in this embodiment may support multiple DRSUs and ACUs, for example, 100, so in this embodiment, when multiple vehicles with ACUs installed travel on a specific line, each ACU may access the DRC of the specific line and receive road condition information reported by the DRSU on the specific line from the DRC, thereby ensuring normal travel of each autonomous vehicle.
Therefore, in order to ensure the normal running of the autonomous vehicle, data transmission between the devices in the vehicle-road coordination system is required. The embodiment of the application provides a data transmission method.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a data transmission method provided in an embodiment of the present application, where the method is applied to a data transmission system, where the data transmission system includes a mobile edge computing platform DRC, a digital track survey unit DRSU, an automatic drive control unit ACU, and a digital track cloud management platform DRCRM, and the method may specifically include the following steps:
step S21, initializing each preset module included in the DRC after the DRC is powered on.
In this embodiment, after the DRC is powered on, the DRC performs an initialization operation on each preset module included in the DRC, that is, initializes the relevant operating parameters and variables of each preset module.
In step S22, after the initialization of each preset module is completed, the DRC acquires configuration information, where the configuration information includes identification information and target address information.
In this embodiment, the configuration information includes identification information and destination address information, where the identification information is used to identify or identify which DRC the DRC is, and the destination address information is used to indicate which DRCRM the DRC is in communication with, i.e., which DRCRM is accessed.
After the initialization of each preset module is completed, the DRC can read configuration information, i.e. read identification information and target address information, from a configuration file pre-stored in the DRC.
Step S23, the DRC sends the identification information to a target DRCRM corresponding to the target address information.
In this embodiment, the DRCRM is responsible for authenticating and registering the DRC, that is, the DRCRM is responsible for determining whether the DRC is a legal DRC in the system, and only the legal DRC can normally perform data transmission. Therefore, the DRC can send the identification information to the target DRCRM corresponding to the target address information after acquiring the configuration information.
In step S24, the target DRCRM determines whether the identification information matches with pre-stored standard information.
In this embodiment, the DRCRM determines whether the DRC is successfully registered by determining whether the identification information sent by the DRC matches with the pre-stored standard information. If the identification information is matched with the pre-stored standard information, the DRC registration is successful; if the identification information does not match the pre-stored standard information, the DRC registration is not successful.
Step S25, the target DRCRM generates a registration success prompt message when determining that the identification information matches the standard information.
In this embodiment, the DRC can accept the access and data transmission of the DRSU or ACU only after successful registration to the DRCRM. In case that the DRC registration is successful, that is, in case that the DRCRM determines that the identification information matches the standard information, in order to enable the DRC to know that the self registration is successful, so that the DRCRM can perform data transmission with the DRSU and the ACU, the DRCRM may generate a registration success prompt information.
Step S26, the target DRCRM sends the registration success hint information to the DRC.
And step S27, data transmission is carried out between the DRDRSU and the ACU and between the DRC and the ACU.
After the DRC acquires the registration success prompt information sent by the DRCRM, the DRC knows that the DRCRM is successfully registered, and can perform data transmission with the DRSU and the ACU. Data transmission between DRC and DRSU and ACU includes data of the control plane and data of the data plane.
In an embodiment, if the DRCRM determines that the identification information does not match the pre-stored standard information, the DRCRM generates registration unsuccessful prompt information, the DRCRM still sends the registration unsuccessful prompt information to the DRC, and if the DRC receives the registration unsuccessful prompt information, data transmission with the DRSU and the ACU is not performed.
By adopting the data transmission method of the embodiment, the DRCRM is used for matching the identification information sent by the DRC with the standard information prestored in the DRCRM, whether the DRC is successfully registered can be judged, under the condition that the DRC is successfully registered, the prompt information of successful registration is generated and sent to the DRC, and the DRC carries out data transmission with the ACU and the DRSU after receiving the prompt information of successful registration.
In an embodiment, the preset modules included in the DRC may specifically include an MC module, an OAM module, a DCSM module, an RCII module, an ACSM module, and an ADSM module, and after initializing each preset module included in the DRC in step S21, the data transmission method provided in this embodiment may further specifically include the following steps:

Step S202, the MC module sends the preparation message to the OAM module.
Step S203, the OAM module acquires the configuration information, where the configuration information includes identification information and destination address information.
Step S204, the OAM module sends the identification information to a target DRCRM corresponding to the target address information.
The MC module is mainly responsible for starting initialization, reporting and summarizing of all the preset modules.
The OAM module is mainly responsible for interaction and communication with the DRCRM and general control of other preset modules.
The DCSM module is mainly responsible for performing control plane communication and data transmission with the DRSU, for example, the first control signaling reported by the DRSU may specifically include: the registration request of the DRSU, the power-on request of the DRSU, the reported alarm information and the like.
The RCII module is mainly responsible for data plane communication and data transmission with the DRSU, for example, the first data information reported by the DRSU may specifically include: DRSU Global Id, road condition information collected by DRSU, etc.
The ACSM module is mainly responsible for performing control plane communication and data transmission with the ACU, for example, the first control signaling reported by the DRSU may specifically include: the registration request of the ACU, the power-on request of the ACU, the alarm information reported by the ACU and the like.
The ADSM module is mainly responsible for data plane communication and data transmission with the ACU, for example, the second data information reported by the DRSU may specifically include: the ACU Global Id, road condition information acquired by the ACU, the ACU driving speed, the ACU position information and the like. The ACU is installed on the autonomous vehicle, and the camera is usually installed on the autonomous vehicle, so the road condition information collected by the ACU can be collected by the camera of the autonomous vehicle.
After the OAM module, the DCSM module, the RCII module, the ACSM module and the ADSM module complete initialization, all the initialization completion messages are reported to the MC module, and after the MC module collects all the initialization completion messages of the preset modules, the MC module generates a preparation message and pushes the preparation message to the OAM module so as to inform the OAM module that a DRCRM (data management system) can initiate a DRC (DRC registration process).
When the OAM module initiates a DRCRM (data management and management) registration process, the OAM module firstly acquires the configuration information, wherein the configuration information comprises identification information and target address information, and after the configuration information is acquired, the identification information is sent to the target DRCRM corresponding to the target address information.
In this embodiment, the DRC is specifically divided into an MC module, an OAM module, a DCSM module, an RCII module, an ACSM module, and an ADSM module, and each preset module completes the function of the DRC, so that the internal division of labor of the DRC is clear, and the data transmission efficiency is improved.
In an embodiment, a configuration file is preset in DRC, where the configuration file records an IP address and a port number of the OAM module, the target address information, and the identification information, and the target address information includes an IP address and a port number of a target DRCRM, and after step S202, the data transmission method provided in this embodiment may further include the following steps:
in step 205, the OAM module obtains the IP address and the port number of the OAM module recorded in the configuration file.
In step 206, the OAM module obtains the IP address and port number of the target DRCRM recorded in the configuration file and the identification information.
And step 207, the OAM module starts a TCP link to access the target DRCRM with the OAM module as a client according to the IP address and port number of the OAM module and the IP address and port number of the target DRCRM.
In step 208, the OAM module sends the identification information to the target DRCRM over the TCP link.
In step 209, the target DRCRM sends the registration success prompting message to the OAM module through the TCP link.

Step S27 in the data transmission method provided in this embodiment may specifically include the following steps:
step S271, the OAM module sends the registration success prompt information to the DCSM module, the RCII module, the ACSM module, and the ADSM module, respectively.
Step S272, the DRSU starts a TCP link to access the server end of the DCSM module by taking the DRSU as the client end according to the IP address and the port number of the DRSU and the IP address and the port number of the DCSM module, the DCSM module receives a first control signaling sent by the DRSU, the DCSM module processes the first control signaling to obtain a first processing result, and the first processing result is reported to the OAM module.

Step S274, the ACU starts a TCP link to access the ACSM module server end with the ACU as a client end according to its own IP address and port number and the IP address and port number of the ACSM module, the ACSM module receives a second control signaling sent by the ACU, the DCSM module processes the second control signaling to obtain a second processing result, and reports the second processing result to the OAM module.

In this embodiment, the OAM module sends the registration success prompt information to the DCSM module, the RCII module, the ACSM module, and after the ADSM module, the DCSM module, the RCII module, the ACSM module, and the ADSM module can modify their own states to be working states, at this time, the DCSM module can receive the first control signaling sent by the DRSU, the RCII module can receive the first data information sent by the DRSU, the ACSM module can receive the second control signaling sent by the ACU, and the ADSM module can receive the second data information sent by the ACU.
After receiving the first control signaling, the DCSM module may process the first control signaling to obtain a first processing result, and report the first processing result to the OAM module. For example, the first control signaling is a registration request reported by the DRSU, and after receiving the registration request reported by the DRSU, the DCSM module first analyzes the registration request reported by the DRSU to obtain an analysis result, and then reports the analysis result to the OAM module.
The RCII module may directly report the data information to the OAM module when receiving the first data information, for example, the first data information may be the traffic information collected by the DRSU Global Id and the DRSU.
After receiving the second control signaling, the ACSM module may process the second control signaling to obtain a second processing result, and report the second processing result to the OAM module. For example, the first control signaling is a registration request reported by an ACU, and after receiving the registration request reported by the ACU, the DCSM module firstly analyzes the registration request reported by the ACU to obtain an analysis result, and then reports the analysis result to the OAM module.
The ADSM module may directly report the data information to the OAM module when receiving the second data information, for example, the second data information may be ACU Global Id, road condition information acquired by an ACU, an ACU driving speed, and ACU position information.

Step S212, the DRCRM acquires the operating system version and the server model of the DRC.
Step S213, the DRCRM establishes an association relationship between the DRC Global ID of the DRC, the operating system version, and the server model, and generates standard information.
In this embodiment, the system may create a plurality of DRC Global IDs in advance and store the DRC Global IDs in the DRCRM, so that the DRCRM may allocate one DRC Global ID to each DRC in the system, and at the same time, the DRCRM may also obtain an operating system version and a server model of each DRC, and for the same DRC, establish an association relationship among the DRC Global ID, the operating system version, and the server model of the DRC, and store the association relationship as standard information in a database of the DRCRM.
In this embodiment, the DRC Global ID is a value within a preset value range, for example, the value range may be 32768 to 65535, and the operating system version and the server model are the actual operating system version and the server model of the DRC.
Because the automatic driving vehicle needs extremely high safety, DRC Global ID, an operating system version and a server model are jointly used as conditions for judging whether DRC is successfully registered, so that the DRCRM can be prevented from generating judgment errors, and the driving safety of the automatic driving vehicle is ensured.
