The vehicle end and the management end shown in fig. 1 may be any terminal device supporting installation of navigation map software, such as a smart phone, a vehicle-mounted computer, a tablet computer, a notebook computer, or a wearable device, but are not limited thereto. The cloud may be a cloud server 130 providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, web service, cloud communication, middleware service, domain name service, security service, CDN (Content Delivery Network), big data and artificial intelligence platform, and the like, which is not limited herein. 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 present application. The method may be applied to the implementation environment shown in fig. 1 and specifically executed by the vehicle end in the implementation environment. It should be understood that the method may be applied to other exemplary implementation environments and is specifically executed by devices in other implementation environments, and the embodiment does not limit the implementation environment to which the method is applied.
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 as follows:
step S210, obtaining the analyzed updated overall protocol.
For example, when the system is updated or new functions need to be added, the protocol may be updated, and therefore, the vehicle end needs to acquire the updated overall protocol from the cloud and parse the protocol.
Step S220, cutting out sub-protocol data which accord with each original protocol in the updated overall protocol according to the updated overall protocol and the original protocol of each data source.
Illustratively, the data source comprises a static data module, a perception data module and the like, the perception data module is used for acquiring dynamic obstacle data through a sensor, a camera and the like of a vehicle, and a fixed static map provided by a map manufacturer is stored in the static data module.
And step S230, recombining the sub-protocol data to generate a complete protocol, so that the data acquired by each data source is analyzed according to the sub-protocol data and then fused according to the complete protocol.
By the method in the embodiment, each data source only needs to be matched with one protocol, namely updated subprotocol data, and each data source does not need to be matched with a plurality of protocol data, and then the data analyzed by each data source is integrated according to the complete protocol. The method is characterized in that a plurality of data sources use a unified data protocol (namely, an overall protocol is updated), the protocol is formulated for a data consumer and the plurality of data sources together, when a new data source is added into a data producer, other data sources do not need to modify a data assembling program of the data source, and the requirement can be met only by cutting out the new protocol.
In an exemplary embodiment, in step S220, the process of cutting out 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 as follows:
step S310, comparing the original protocol with the updated overall protocol to generate a matching result.
Illustratively, the original protocol carries a protocol applicable version, and after the overall protocol is updated, the overall updated protocol is matched with the original protocol to determine whether the overall updated protocol conforms to the applicable version. If the data is in accordance with the sub-protocol data, the sub-protocol data can be cut, and if the data is not in accordance with the sub-protocol data, the sub-protocol data cannot be cut.
Step S320, determining whether to generate a complete protocol according to the matching result.
When the data source is worth explaining, whether the complete protocol is generated or not is determined according to the matching result so as to ensure that the complete protocol is suitable for each data source.
In an exemplary embodiment, in step S310, comparing the original protocol with the updated overall protocol, and generating a matching result at least includes: step S410 and step S420.
Step S410, if the updated overall protocol has the subprotocol which accords with the original protocol, cutting out the subprotocol data of the subprotocol in the updated overall protocol, and generating a matching result which is successful matching.
It is worth noting that successful matching indicates that the data source is suitable for updating the overall protocol.
Step S420, if there is no subprotocol in the updated overall protocol that conforms to the original protocol, the generated matching result is unsuccessful.
It is worth noting that a match that is unsuccessful 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 a complete protocol according to the matching result at least includes: step S510 and step S520.
Step S510, if the matching results of all the data sources are successful, recombining the updated overall protocol and the sub-protocol data to generate an overall protocol.
In this embodiment, the protocol is updated only if all the data sources are successfully matched, so as to generate a complete protocol, thereby avoiding that individual data sources cannot be applied to the updated protocol.
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 recombining each piece of sub-protocol data to generate a complete protocol at least includes: step S610 and step S620.
Step S610, obtaining encapsulation data of each data source, wherein the encapsulation data is generated after the data source serializes and encapsulates the acquired data according to the subprotocol 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, the packaged data is verified, and if the packaged data is complete and the format is correct, the packaged data is determined to be applicable data; and if the packaged data is abnormal, discarding the packaged data.
In this embodiment, the packet in the encapsulated data checks the data format, the serialization is performed through the sub-protocol data, and if the serialization success data packet is complete and the format is correct, otherwise, the data packet is abnormal, and the data is discarded.
In an exemplary embodiment, after obtaining the encapsulated data of each data source, the method further includes: monitoring data transmission of a data source, and if the encapsulated data is not received within a preset time, generating alarm information of abnormal data transmission; and if the encapsulated data is received within the preset time, generating feedback information with normal data transmission.
It is worth mentioning that alarm information and feedback information are generated to facilitate the knowledge of the data transmission.
Illustratively, the protocol files all adopt proto protocol, and the complete proto file is a protocol provider which pushes the protocol file to a fixed position through a cloud or adb tool.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
