摘　　要：设计了一个基于OPC技术的养猪场实时监控系统。将不同型号的PLC及PC机通过Profibus-DP和工业以太网连接,并揉合了OPC技术,解决了不同型号的PLC之间数据传输较困难的问题。结合组态软件的通信功能,实现了各类PLC和PC机的无缝连接。该系统实现了养猪场的无人值班,实时性好,可靠性高。A real-time monitoring system for hoggery based on OPC technology was designed. Combined with OPC technology, various type PLCs and PC were connected by Profibus-DP and industrial EtherNet to resolve problem which data were transmitted difficultly among PLCs. With communication function of configuration software, seamless connection among PLCs and PC was realized. The system can realize non-attended monitoring, with good real-time and high reliability.
