Embodiment Construction

[0042] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 As shown, this example provides a transmission control method for an electronic shift sign, including the following steps:

[0044] Step S1, grouping files through the server file management unit;

[0045] Step S2, divide the file into blocks through the file management unit of the server, and establish a channel for each file group;

[0046] Step S3, the server cache control unit negotiates the initial cache with the client cache management unit through the channel management module;

[0047] Step S4, the client file management unit sends a file request;

[0048] In step S5, the server cache control unit implements coded transmission through a shared channel;

[0049] In step S6, the client cache management unit decodes the coded information after receiving it, and sends it to the client file managemen...

Abstract

The present invention provides a transmission control method and system of an electronic shift card. The transmission control method of the electronic shift card includes the following steps: step S1, grouping files by a server file management unit; step S2, grouping files by a server file management unit The file is divided into blocks, and a channel is established for each file group; step S3, the server cache control unit negotiates the initial cache with the client cache management unit through the channel management module; step S4, the client file management unit sends a file request; step S5, The server cache control unit implements coded transmission through a shared channel; step S6, the client cache management unit decodes the coded information after receiving it, and sends it to the client file management unit to realize file formation and playback. The invention realizes distributed buffering, realizes encoding transmission through shared channels, saves storage space and reduces bandwidth occupied by wireless network transmission, and can improve response speed and performance.

Description

technical field [0001] The invention relates to a method for controlling electronic shift boards, in particular to a method for controlling transmission of electronic shift boards, and to a transmission control system using the method for controlling the transmission of electronic shift boards. Background technique [0002] The electronic class card is equipped with a digital electronic frame or an LED display, usually an electronic screen hanging at the door of the classroom to display class information. Through the display screen, the name information of each class, the situation of teachers and various activities, the notification of various activities, and the deeds of advanced individuals and collectives in the class can be released. It is a good interactive channel between schools, teachers, students and parents. At present, the electronic class board system generally adopts an embedded system, and the storage capacity is not large. At the same time, the transmission b...
