基于数据库的远程测控自适应命令链设计实现

远程测试系统将分布在各个节点的测试数据、测试设备通过计算机网络连接在一起,构成一个集数据采集、传输、处理和应用的综合信息网络,实现了远程控制和操作测量仪器,获取和传递测试信息与数据;分析了传统的远程测试与控制命令链的结构,针对其缺点与不足,提出一种基于数据库的自适应控制命令的建立方法,有效地解决了传统控制命令链的灵活性低、不易扩展等缺点,使远程测试系统的通用性和可扩展性得到提高;将该方法应用于网络化远程测试与故障诊断系统中,通过向数据设备表中加入新设备的参数来动态扩充测试前端的测试设备种类,自适应生成控制命令链,实现了对远程设备的控制,取得了良好的效果。

Design and Implementation for Self-adaptive Command Chain in Remote Testing and Control System Based on Database

In remote testing system,the test data and equipments distributed on each node are linked through network,that construct an integrated information network,in order to make long-distance control and operation,by getting and delivering the test information and data.The paper analyzes the composition of traditional command-chain in long-distance measurement and control system,and effectively solves the defects of low-agility and inexpansibility,so as to improve the currency and expansibility of the whole syste...
