Embodiment Construction

[0028] The present invention introduces an XML incremental transmission and interaction method oriented to multi-disciplinary virtual experiment platform based on XML structural characteristics and virtual experiment characteristics. This method incrementally transmits experimental data during virtual experiment interaction and establishes it on the server Cache, thereby greatly reducing the amount of network transmission data, improving the real-time nature of virtual experiment interaction, and proposes a new virtual experiment front and back interaction method, which has good scalability and decoupling.

[0029] The present invention will be described in detail below with reference to the drawings and examples.

[0030] Such as figure 1 As shown, the method of the present invention is divided into 5 steps in total, which are specifically described as follows:

[0031] (1) When initializing the client virtual experiment scene, the server caches the initial scene XML data, and estab...

Abstract

The invention discloses an extensible makeup language (XML) incremental transmission and interaction method for a multidisciplinary virtual experiment platform and belongs to the technical field of computer application. In an initiation process, a server side caches and writes XML data of an initial scene into a disk and creates a cache and file index; a client sides detects the experiment operation action of a user, and then packages an experiment command and incremental data and then sends the packaged experiment command and incremental data to the server side; the experiment command is resolved: if the experiment command is an intelligent guide command, new XML data is generated based on the incremental data and cached XML data, the cache, disk file and corresponding index are updated,and intelligent guide service is carried out; if the experiment command is a backspacing scene command, a corresponding virtual experiment scene XML file is found based on backspacing times and indexinformation; and if the experiment command is any other command, the XML data is acquired from the cache and sent to a corresponding application server, otherwise the processing result acquired from the server side is sent to the client side. By using the XML incremental transmission and interaction method for the multidisciplinary virtual experiment platform, the data transmission quantity in the virtual experiment interaction process is reduced and the instantaneity of the whole experiment process can be guaranteed.

Description

Technical field [0001] The invention belongs to the field of computer application, and specifically relates to a method for XML incremental transmission and interaction oriented to a multi-disciplinary virtual experiment platform. The method is suitable for a virtual experiment environment with frequent real-time interaction and large data transmission volume. A new virtual The interactive method before and after the experiment. Background technique [0002] With the rapid development of virtual technology and network technology, it has become possible to construct virtual laboratories through information networks. Virtual experiment teaching can solve the problems of incomplete components, shortage of high-end equipment and difficult experiment management for colleges and universities, but also conducive to the development of students' innovative thinking and improve students' practical ability, so it provides students with a real-time and friendly virtual experiment environment...
