Description
technical field [0001] The invention relates to an industrial monitoring system, in particular to an OPC technology-based circuit breaker withstand voltage testing process monitoring system. Background technique [0002] OPC (OLE for Process Control, object connection and embedded technology for process control) is the default solution for system interconnection in the industry, which brings convenience to industrial monitoring programming, and users do not have to worry about the difficulty of communication protocols. OPC technology is a technology based on Microsoft OLE / COM, which has become an industry standard. It supports a variety of development protocols to meet the needs of information integration. Using OPC technology, IBMS system allows other systems to monitor it and control, and can also open the internal data and various event records of the IBMS system. In recent years, with the establishment of industrial control systems, OPC technology has been widely used i...
