【摘要】 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。更多还原

【Abstract】 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 tes- ting 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 networked test of the engine test-bed.With the data-pushing technology,the cross-platform advantage of Java,and embedding the Applet into Web page,we have solved the problems above.Furthermore,it is a- ble to use the client computers to process the data.更多还原
