Abstract

The invention provides a data synchronization method and device, computer equipment and a storage medium. The method comprises the following steps: establishing communication connection with a plurality of control terminals; converting the synchronization data sent by each control terminal into a corresponding target synchronization instruction; obtaining a latest historical instruction between the server and each large screen; and if all the latest historical instructions are the same, sending the target synchronization instruction to the plurality of large screens to so that the plurality of large screens perform data synchronization according to the target synchronization instruction. According to the method and the device, the problem that synchronous updating and synchronous display of the data cannot be realized in the prior art is solved, the data interaction performance of a visual large-screen system is improved, and the requirement of the large-screen system for timely synchronization of the data is met.

Description

technical field

[0001] The present invention relates to the technical field of data synchronization, in particular to a data synchronization method, device, computer equipment and storage medium. Background technique

[0002] The visual large-screen system can display various workstations, network signals and various video signals, and the screen can be arbitrarily opened, enlarged, reduced and superimposed; the application field of the visual large-screen system is becoming more and more extensive with the advent of the digital age. Most of them are monitoring, centralized dispatching and communication systems, and the applied industries are mainly distributed in the fields of transportation, government, finance, energy and radio and television.

[0003] However, the current visual large-screen system controls each large-screen individually through an independent server, and the system data interaction is poor, and the data cannot be updated and displayed synchronously. C...
