Embodiment Construction

[0028] According to the structural features of XML and the characteristics of virtual experiments, the present invention introduces an XML incremental transmission and interaction method oriented to a multidisciplinary virtual experiment platform. Cache, thereby greatly reducing the amount of network transmission data, improving the real-time performance of virtual experiment interaction, and proposed a new virtual experiment front-background interaction method, which has good scalability and decoupling.

[0029] The present invention will be described in detail below in conjunction with accompanying drawings and examples.

[0030] Such as figure 1 As shown, the inventive method is divided into 5 steps in total, is specifically described as follows:

[0031] (1) When initializing the virtual experiment scene on the client side, the server caches the initial scene XML data, and builds a cache address index according to the connection value; at the same time, writes the XML dat...

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 index information; 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 applications, and specifically relates to an XML incremental transmission and interaction method for a multidisciplinary virtual experiment platform. The method is suitable for a virtual experiment environment with frequent real-time interactions and large data transmission. The method of interaction between the front and back of the experiment. Background technique [0002] With the rapid development of virtual technology and network technology, virtual laboratories constructed through information networks have become possible. Virtual experimental teaching can solve problems such as incomplete components, high-end equipment and devices, and experimental management difficulties for colleges and universities. It is also conducive to the development of students' innovative thinking and improvement of students' practical ability, so it provides a real-time and friendly virtual experimental environment for st...
