分布式网络化测试系统设计

以某大型复杂装备远程测试系统为例,给出了基于DCOM的分布式网络化虚拟仪器测试系统的体系结构.该网络化测试系统体系结构采用DS技术作为客户端和测试端连接的中间件,并采用C/S、B/S混合模式使系统各COM/DCOM组件通过网络实现"无缝"连接.DCOM技术的应用使得各网络测试节点成为服务的本体,可以响应不同客户的测试需求,实现了良好的数据传输、安全管理和远程仪器控制.DS技术的使用进一步简化了计算机和测试应用之间的数据交换,达到了良好的实时传输效果.

Distributed Network Test System Design

This paper illustrated the distributed network test system framework based on DCOM by some complex equipments,the network test system used DS technology as its network communication layer to link the client-sides and test-sides,and used C/S and B/S mode to connect the COM/DCOM component tightly.DCOM technology made the network test node become the server entity and can answer to the test requirement of different clients.The distributed network test system based on DCOM realized good data transmission,safety management and distance instruments control.DS technology facilitated the data exchange between the computer and test application and realized good real-time transfers.
