Remote Virtual Circuit Experiment And Realization

Remote experiment education(REE) on circuit as the member of REE society, is on its beginning. REE systems should be reality, with friendly user interface and accurate simulate results; and also be high interactive, with rapid user-interact response; making the effect of experiments close to that of real experiments. Most of current simulate software on the internet can not meet both request, resulting in the low development of REE on circuit.To meet both request, this article produce and annotate a communication mode fit to REE. This module bind the communication between front-end and back-end of the system onto HTTP protocol of Apache server, make the system more secure and flexible. Due to Apache's module design, the application server is designed as a Apache's module, enhance the performance of system.This article also annotate the Real-time continual simulation technology on Internet and it's optimization. Real-time continual simulation is one of the system's keystone but also a thorn. This article annotates the time-slice strategy, splitting entire simulation process into many time-slices, along with context-resetting and interaction response mechanism. And also introduces the dynamic time-slice algorithm to optimize it.Stand on the two, we design and develop a remote virtual circuit experiment platform, based on some technology now available, such as virtual reality, network and simulation. The platform is in B/S model, the front-end which is very friendly is programmed with Flash, and the back-end witch is high performed is developed based on XSPICE, a simulate software. Using two technologies this article annotated, to bind the front-end and the back-end, The platform opens a new door to REE.
