基于OPC的边缘服务器采集系统软件设计

Software Design of Edge Server Acquisition System Based on OPC

针对车间的设备种类和数量众多,导致底层设备的通信接口和协议的多样化且不兼容等问题,设计了一种基于OPC(OLE for Process Control)协议的边缘服务器采集软件。使用C#语言的WPF框架、TreeJS技术,以及OPC UA(OPC Unified Architecture)标准协议,结合了边缘服务器延迟性低的优点,设计了具有用户登录、数据采集、管理、查询,3D展示等功能的上位机软件。为验证系统的可行性,对其进行测试,实现了数据的采集和Web端的3D展示,证明该系统可以满足车间的基本需求。

Aiming at the problems of diverse and incompatible communication interfaces and protocols of underlying devices due to the large variety and quantity of equipment in the workshop,an edge server acquisition software based on the OPC(OLE for Process Control)protocol is designed in this paper.Using the WPF framework of C#language,TreeJS technology and the OPC Unified Architecture(OPC UA)standard protocol,combined with the advantages of low latency of edge servers,a host computer software with functions such as user login,data collection,management,query,and 3D display was designed.In order to verify the feasibility of the system,it is tested and realized data collection and 3D display on the Web,proving that the system can meet the basic needs of the workshop.
