The terminal device may communicate with the navigation server through a wireless network such as 3G (third generation mobile information technology), 4G (fourth generation mobile information technology), 5G (fifth generation mobile information technology), and the like, which is not limited herein.
Referring to fig. 2, fig. 2 is a flowchart illustrating a data delta fusion method according to an exemplary embodiment of the application. The method can be applied to the implementation environment shown in fig. 1 and is specifically executed by a vehicle end in the implementation environment. It should be understood that the method may be adapted to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and the implementation environments to which the method is adapted are not limited by the present embodiment.
As shown in fig. 2, in an exemplary embodiment, the data delta fusion method at least includes steps S210 to S230, which are described in detail below:
Step S210, the updated overall protocol after analysis is obtained.
For example, when a system is updated or a new function needs to be added, a protocol may be updated, so that a vehicle end needs to acquire an updated overall protocol from a cloud end and analyze the protocol.
Step S220, according to the updated overall protocol and the original protocol of each data source, cutting out the sub-protocol data conforming to each original protocol in the updated overall protocol.
The data source comprises a static data module, a perception data module and the like, wherein the perception data module is used for acquiring dynamic obstacle data through a sensor, a camera and the like, and a fixed static map provided by a map manufacturer is stored in the static data module.
Step S230, reorganizing each piece of sub-protocol data to generate a complete protocol, so that the data collected by each data source are fused according to the complete protocol after being analyzed according to the sub-protocol data.
By means of the method in the embodiment, each data source only needs to be matched with one protocol, namely updated sub-protocol data is not needed to be matched with a plurality of protocol data for each data source, and then the analyzed data of the data sources are integrated according to the complete protocol. The data sources use a unified data protocol (namely, updating the whole protocol), the protocol is formulated for the data consumer and the data sources together, when a new data source is added into a data producer, other data sources can meet the requirement of only needing to do new protocol cutting without modifying a data assembly program, the collected data can be assembled without modifying the program, only needing to reorganize the data according to the new protocol (namely, the whole protocol), the data among the data sources does not need to transmit the field value of the whole updated whole protocol, only needing to cut sub-protocol data, the field length of the data transmission is reduced, and the bandwidth required by the data transmission is reduced.
In an exemplary embodiment, in step S220, the process of clipping the sub-protocol data conforming to each original protocol in the updated overall protocol according to the updated overall protocol and the original protocol of each data source may include step S310 and step S320, which are described in detail below:
Step S310, comparing the original protocol with the updated whole protocol to generate a matching result.
The original protocol carries an applicable version of the protocol, and after the updated overall protocol comes out, the updated overall protocol is matched with the original protocol to determine whether the updated overall protocol accords with the applicable version. If the data is matched with the data, the sub-protocol data can be cut, and if the data is not matched with the data, the sub-protocol data cannot be cut.
Step S320, according to the matching result, whether the complete protocol is generated is determined.
When the method is worth describing, whether the complete protocol is generated is determined according to the matching result so as to ensure that the complete protocol is applicable to each data source.
In an exemplary embodiment, in step S310, the process of comparing the original protocol with the updated overall protocol to generate a matching result at least includes: step S410 and step S420.
Step S410, if the updated overall protocol has a sub-protocol conforming to the original protocol, clipping sub-protocol data of the sub-protocol from the updated overall protocol, and generating a matching result as a successful matching result.
It should be noted that a successful match indicates that the data source is suitable for updating the overall protocol.
Step S420, if the updated overall protocol has no sub-protocol conforming to the original protocol, the generated matching result is unsuccessful matching.
It should be noted that an unsuccessful match indicates that the data source is not suitable for updating the overall protocol.
In an exemplary embodiment, in step S320, the process of determining whether to generate the complete protocol according to the matching result at least includes: step S510 and step S520.
And step S510, if the matching result of all the data sources is successful, reorganizing the updated whole protocol and the sub-protocol data to generate a complete protocol.
In this embodiment, only if all the data sources are successfully matched, the protocol is updated to generate a complete protocol, so that the situation that individual data sources cannot be suitable for the updated protocol is avoided.
Step S520, if the matching result of any data source is unsuccessful, the process is ended.
In this embodiment, if any data source is not successfully matched, no protocol update is performed.
In an exemplary embodiment, in step S230, the process of reorganizing each of the sub-protocol data to generate a complete protocol at least includes: step S610 and step S620.
Step S610, obtaining the package data of each data source, wherein the package data is generated by the data source after serializing and packaging the collected data according to the sub-protocol data.
In this embodiment, after the data source collects the data, the data is serialized and encapsulated according to the sub-protocol data.
Step S620, checking the encapsulated data, and determining the encapsulated data as applicable data if the encapsulated data is complete and has a correct format; and discarding the encapsulated data if the encapsulated data has data abnormality.
In this embodiment, the packet in the encapsulated data checks the data format, and uses sub-protocol data to perform serialization, if the serialization is successful, the packet is complete and the format is correct, otherwise, the packet will have data exception, and the data is discarded.
In an exemplary embodiment, after obtaining the package data of each data source, the method further includes: monitoring data transmission of a data source, and if the package data is not received within a preset time, generating alarm information of abnormal data transmission; if the package data is received within the preset time, generating feedback information with normal data transmission.
It is worth to say that the alarm information and the feedback information are generated so as to know the data transmission condition.
Illustratively, the protocol files all employ the proto protocol, and the complete proto file is the protocol provider that pushes the protocol file to a fixed location through a cloud or adb tool.
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, and should not limit the implementation process of the embodiment of the present invention.
