摘　　要：基于网络测控系统同步方法与网络传输延迟的问题,提出基于同步控制技术的开放式网络化测控系统设计。首先,对精准时钟同步协议进行分析,分析其体系结构。之后,对系统的总体模型进行设计,主要包括远程协同测控中的要素。然后,对开放式网络化测控系统的软件模块分析,并且对设计的系统进行测试。通过测试结果表示,能够有效满足多点传感器信号加载、收集、激励等同步测量与控制的实际使用需求。Based on the synchronization method of networked measurement and control system and the problem of network transmission delay,an open networked measurement and control system design based on synchronization control technology is proposed.Firstly,the precise clock synchronization protocol is analyzed and its architecture is analyzed.Then,the overall model of the system is designed,including the elements of remote cooperative measurement and control.Then,the software module of the open networked measurement and control system is analyzed,and the designed system is tested.The test results show that it can effectively meet the practical requirements of synchronous measurement and control of multi-sensor signal loading,collection,excitation and so on.
