基于OPC UA的云端远程控制系统

Cloud Server Remote Control System Based on OPC UA

控制算法的研究多通过模拟仿真的方式实现,但真正的应用还需要实际工程的测试检验,成熟的算法控制往往也需要应用测试,因此针对算法控制和工程之间产生的时间和空间限制,提出基于OPC UA的云端远程控制系统。该系统通过KEPServer软件和OPC技术解决不同硬件设备控制时的数据远程传输问题,同时将算法放入云服务器有效打破了时空上的壁垒,实现了随时随地远程控制。在实际应用中,远程控制系统利用预测PI控制算法已成功对企业的色谱柱温度进行远程控制,达到了不错的效果。

The research of control algorithm is mostly realized by simulation,but the practical application still needs to be tested in practical engineering.Mature algorithm control often needs application test.Therefore,aiming at limitation of the time and space between algorithm control and engineering,a cloud remote control system based on OPC UA is proposed.The problem of remote data transmission controlled with different hardware devices are solved with adopting KEPServer software and OPC technology.At the same time,the algorithm is put into the cloud server,which breaks the barriers in time and space effectively.Remote control can be realized anytime and anywhere.In practical application,the temperature of chromatographic column of the enterprise has been successfully controlled by using predictive PI control algorithm,and good results are achieved.
