Embodiment Construction

[0211] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0212] First of all, it needs to be explained that the distributed storage system in the present invention is a distributed storage system constructed based on algorithms such as ETCD algorithm, Zookeeper algorithm or Paxos algorithm, and the CDN server is a preset content delivery network (ContentDelivery Network, CDN) A node server, the node server can communicate with the distributed storage system and the client respectively. The client refers to the control system capable of realizing specific functions, and in some cases, may directly refer to the controller of the control system. For example, the client may be a pre-installed vehicle-m...

Abstract

The invention relates to the technical field of computer control, and specifically provides a data acquisition method, apparatus and system for solving the technical problem of how to enable a vehicleto reliably and securely acquire data. To this end, the data acquisition method in the invention comprises the following steps: downloading target data required by a client to a CDN server in advanceby using a distributed storage system, and receiving a downloading identifier fed back by the CDN server, so that the client can indirectly acquire the data (the client acquires the downloading identifier in the storage system at first, and then acquires the target data stored in the CDN server according to the downloading identifier) in a service terminal through the storage system, so that thedata acquisition security is ensured. Based on a node election mechanism, when a master control node in the distributed storage system is ineffective, a controlled node can immediately perform mastercontrol node election, thereby ensuring the reliable operation of the storage system, that is, ensuring the data acquisition reliability. Meanwhile, the apparatus and system of the invention can perform and implement the above method.

Description

technical field [0001] The invention relates to the technical field of computer control, in particular to a data acquisition method, device and system. Background technique [0002] Advanced Driver Assistance Systems (Advanced Driver Assistance Systems, ADAS) is a vehicle that can identify, detect and track dynamic / static objects based on the surrounding environment of the vehicle and navigation map information during vehicle driving, and then analyze the safety of the vehicle's driving conditions. defense system. Specifically, the navigation map information acquisition methods mainly include a direct acquisition method and an indirect acquisition method. [0003] The direct acquisition method means that the vehicle directly communicates with the service end (the server of the map provider) to obtain relevant map information, but the vehicle data is easily stolen by the service end during the communication process, so the communication security of this method is poor.
