Embodiment Construction

[0047] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] The Internet of Things (IoT) is the "Internet connected to everything", which is an extended and expanded network based on the Internet. It is a huge network formed by combining various information sensing devices with the network. , any place, the interconnection of people, machines and things. Usually, the Internet of Things system based on the Internet of Things includes a general service node and multiple collection nodes, and data transmission is realized between the collection node and the service node through data synchronization signaling. Moreover, in order to reduce the pressure of data transmission, the collection node usually only synchronize...

Abstract

The invention discloses a data synchronization method and device, and belongs to the technical field of Internet of Things. The method comprises the following steps: acquiring file information corresponding to a first type of data synchronization signaling; determining a popularity value of the file according to the file name and the synchronization time; selecting a target file from the files according to a preset popularity threshold value and the popularity values of the files; under the condition that the preset time condition is met, uploading the current version of the target file to a service node, so that the service node stores a file which is relatively high in synchronization probability and contains original data in advance. Aiming at said part of files, when the service node has a synchronization requirement, real-time synchronization does not need to be carried out from the acquisition node, and the files can be directly acquired locally. Therefore, the synchronization requirement of the service node on the file containing the original data can be met in a relatively large probability, the condition of overlong transmission time caused by real-time response to the first type of data synchronization signaling is effectively reduced, and the service level of the Internet of Things system can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a data synchronization method and device. Background technique [0002] Usually, the Internet of Things system includes a general service node and multiple collection nodes. After the acquisition node collects the original data, it first preprocesses the original data at the local end to obtain the processing result with a small data volume, and then transmits the processing result to the service node through the preset routine data synchronization command, and does not The original data is transmitted to the service node to avoid the problem of long transmission time caused by direct transmission of original data. However, in some application scenarios, the service node needs to obtain some raw data from the collection node for personalized analysis. Since the data volume of the original data is larger than the processing result, it may lead to a longer data tra...
