Description

Resource synchronization method and device Technical Field The invention relates to the technical field of Internet, in particular to a method and a device for synchronizing resources. Background The cloud control platform generally adopts a multi-stage architecture and consists of one set of regional cloud and a plurality of sets of edge clouds. The regional cloud and the edge cloud are located in different network environments, and data transmission is performed through a wide area network or a private line. The regional cloud is used for managing devices in a preset region and data generated by the devices, and the edge cloud is used for carrying out relevant calculation on the data uploaded by the nearby devices, wherein the devices and the data are called resources in the cloud control platform. For example, in the field of autopilot, including devices such as an autopilot vehicle, an RSU (Road Side Unit), a Road Side collaboration Unit, and the like, when new data is obtained, the devices may connect the edge cloud nearby according to a geographic area, and upload the new data to the edge cloud for calculation, and the area cloud provides a management platform, so that the devices and the data may be managed. Because of different usage manners of the resources, the resources may have different storage manners in the regional cloud and the edge cloud. If the information of the RSU is provided with the deletion and correction service in the regional cloud, the data can be stored in the mysql database, and if the edge cloud is more than the edge cloud, the edge cloud finds the RSU needing to issue the event through the coordinate point and the influence range of the event, and sends the event to the RSU, so that the information of the RSU is generally stored in the mongdb database, a spatial index is created for the position of the RSU, and the RSU is quickly searched through the spatial index. At present, when the storage modes of regional cloud and edge cloud resources are different, the method for realizing the synchronization of regional cloud and edge cloud resources comprises the steps of adding storage nodes which are equivalent to the storage modes of regional cloud resources at the edge cloud, when the regional cloud resources are updated, loading resources to be synchronized from the regional cloud by using a resource loading program, synchronizing the loaded resources to be synchronized from the regional cloud to the peer storage nodes of the edge cloud, adding the resource loading program, loading the resources from the peer storage nodes of the edge cloud, and storing the loaded resources by using the resource storage modes of the corresponding resources in the edge cloud. However, when the edge cloud corresponding to the regional cloud is more, the peer storage nodes and resource loading programs which need to be added are also increased, so that the construction cost of the cloud control platform is greatly increased. Disclosure of Invention The invention provides a resource synchronization method and a resource synchronization device, which can directly synchronize the resources updated by an area cloud to an edge cloud without adding a peer-to-peer storage node and an additional resource loading program, thereby saving the construction cost of a cloud control platform.
