One embodiment of the present invention provides a file synchronization method applied to a holographic scene, including:
s010 issues the client to obtain the picture file uploaded by the new design;
s020 sending the newly designed and uploaded picture file to a message queue of a file server connected with the releasing client through a back-end program;
s110, the subscription client starts a background process to monitor whether the picture file is sent from the message queue of the file server; the publishing client and the subscribing client are connected with a message queue of the same file server;

Specifically, in the prior art, the public network picture is pulled in a http short connection manner, the loading speed of the holographic work is seriously affected due to the influence of the network bandwidth of the environment where the client is located and the bandwidth of the server, one work needs to be loaded for five minutes or even longer, and the network transmission is very unstable.
The file server is kept always started, and the synchronous program can be started to automatically start and monitor the message queue of the file server. Background personnel use the issuing client to operate and upload the design picture file and store the design picture file. The publishing client sends the uploaded picture file to a message queue in a picture link form through a back-end program, the QOS is set to be 1, the message is reachable, the file server receives the message and can be confirmed, and a PUSCK message is transmitted. If there is an identifiable transmission failure, either the communication connection or the sending device, or if a period of time has elapsed without the acknowledgement being received, the publishing client will send the message again with the DUP position 1 of the header. The message arrives at the file server at least once. Both SUBSCRIBE and UNSUBSCRIBE use a level 1 QoS. If the publishing client does not receive the PUBACK information (whether an application-defined timeout or a failure detected and then the session restarted), the publishing client will resend the PUBLISH information and will DUP location 1. When a duplicate picture file is received, the file server resends the message to the subscriber server and sends another delete message. The file server pushes the picture files of the subscription subjects predetermined by the subscription client to the corresponding subscription client. When the subscription client monitors that a new picture file arrives at the subscription subject, a new record is written into the local memory database, and the record state is not downloaded. The file server program polls the local memory database at regular time and starts downloading when finding a new connection. The file server memory database adopts a queue processing mode: the first inserted data is always downloaded first, and the first-in first-out principle is adopted. When the picture file is partially downloaded, the partial download state of the file is recorded, and another task of the file service program is to periodically query the partially downloaded file of the memory database once, so that the picture file which is downloaded is not deleted from the memory database.
The method mainly aims at the problem that the picture file of the holographic house work is too large, the large file is synchronously dropped to the local server at the front end, and the holographic house machine points to the file server in the local area network to pull the data picture, so that the file loading speed is increased in the local area network. According to the invention, by adopting the technical scheme of sinking the file service, the file server is sunk to the local area network of the holographic house, the gigabit transmission of the intranet is realized, the basic target of timely incremental updating of files is achieved, the ideal effects of a data public network and a picture intranet are realized, the effect of loading works within 5 seconds is realized, the user experience is optimized, the waiting time is reduced, the slow time for loading the works is advanced to the incremental updating when the files are uploaded, the file synchronization efficiency is further accelerated, and the product display efficiency of the holographic scene is improved.
