Description

Service state configuration method, system and storage medium based on vehicle-cloud integration Technical Field The invention relates to the technical field of internet of vehicles, in particular to a method, a system and a storage medium. Background As the electronic and electrical architecture of the automobile gradually evolves from a distributed ECU to a centralized domain control and cloud cooperative architecture, the vehicle-end function is also controlled by a traditional cured ECU to turn to a dynamic service governance mode based on SOA (Service Oriented Architecture ). The service state of the vehicle end needs to be reported to the cloud in real time so as to support remote diagnosis, OTA upgrading, vehicle-cloud integrated application and even intelligent driving of vehicle-cloud cooperation. Under a vehicle-cloud integrated architecture, the cloud end always monitors and schedules services in the vehicle in a centralized manner through a cloud desktop or a unified management and control platform. The cloud relies on the service state information periodically uploaded by the vehicle to realize service discovery, policy arbitration, resource scheduling and remote configuration. However, existing service state acquisition mechanisms commonly employ fixed periodic polling, e.g., SMS (Service Management Service) at the vehicle end typically queries for service state at 500ms periods, SDM (Service Discovery Manager) typically queries for service information at 5s periods. When a service is frequently changed in a short period, the polling mechanism may not capture all the changes, resulting in state report loss, and at the same time, even if the service state remains unchanged, the report is repeated according to a fixed period, resulting in redundant transmission and CPU occupation. The reporting mechanism based on the fixed period is tolerant under the single vehicle scale, but in the scene of large-scale motorcade access to the cloud desktop, obvious performance bottlenecks and communication burdens are brought, for example, the state consistency is insufficient, frequently-changed services can be inconsistent with the cloud end and influence the accuracy of cloud scheduling and policy execution, the resource cost is high, the periodical polling causes the increase of CPU (central processing unit), bandwidth and cloud storage pressure at the vehicle end and is unfavorable for large-scale vehicle cloud integrated deployment, and the dynamic perception is lacking, so that the conventional mechanism cannot effectively distinguish key changes and invalid repetition, and the data transmission among the vehicle clouds is lack of intelligence and differentiation. Therefore, how to design a service state notification mechanism integrating event driving and periodic polling in a vehicle-cloud integrated scene, so that state loss can be avoided, redundant reporting can be reduced, and meanwhile, real-time perception and consistency of a cloud desk to vehicle-end services are guaranteed, so that the technical problem to be solved in the field is urgent. Disclosure of Invention The embodiment of the invention provides a service state configuration method, a service state configuration system and a storage medium based on vehicle cloud integration, which are used for solving the problems that the existing vehicle networking is easy to lose report, and the real-time perception and consistency of cloud to vehicle-end service are poor. In order to achieve the purposes of avoiding state report loss, reducing redundant report and guaranteeing real-time perception and consistency of cloud desk to vehicle end service based on the service state notification mechanism integrating event driving and periodic polling, the invention adopts the following technical scheme: in a first aspect, an embodiment of the present invention provides a service state configuration method based on vehicle-cloud integration, which is applied to an electronic device, and the method includes: acquiring target parameter information through a vehicle-end service management unit, and generating a standardized service event and corresponding service parameters based on a first preset algorithm group; Acquiring service subscription information corresponding to the service parameters through a service discovery management unit, and generating corresponding management parameters based on a second preset algorithm group; Based on the service parameters, the management parameters and the arrangement parameters issued by the cloud, uniformly arranging the standardized service events through a daemon unit, determining an event sequence which is subjected to jitter removal and sequencing, and distributing the event sequence to three transmission channels of real time, batch and heartbeat according to priority; Based on the event sequence, the management parameters and the channel and rate strategy issued by the cloud, three uplink messages with serial
