基于数据推送组建B/S模式虚拟仪器测试系统

Research on B/S model virtual instrument test system based on data-pushing technology

虚拟仪器技术结合网络技术,推动着传统测试系统朝着网络化方向发展。基于B/S模式的虚拟仪器系统进一步把测试延伸到Intranet/Internet,突破了地域的限制,使测试工作变得更加便捷。这种模式下,软件部署和维护非常容易。但传统的B/S模式以客户端请求,服务器回传整个Web页面,效率低,且不易与实际测试同步。本文以发动机网络化台架测试为例,利用数据推送技术,依托Java跨平台的优势,在Web页面中嵌入Applet,不仅克服了上述问题,而且利用客户端对数据进行适当处理,实现基于B/S模式的虚拟仪器系统。

The integration of virtual instrument technology with network technology makes traditional test systems developed into networked test systems.With the virtual instrument based on B/S model,the testing work enters into Intranet/Internet without the limitation of space.It makes the software deploying and maintenance very easy.But the efficiency of the 'request-response' working method of traditional B/S model is not very good,and it is hard to keep pace with the actual test.This paper gives an example of netw...
