| 摘 要： | OPC是工业控制领域中应用程序互操作规范。针对自主研制的LonWorks网络，实现了其OPC server，使得OPC client软件能方便地从本地或远程访问这种网络。在讨论了应用程序的实时数据库、图形用户接口、OPC对象、I/O读写等实现原理的基础上，研究了该OPC server的写命令处理和多线程同步等关键技术。

| Abstract: | OPC(OLE for process control) is the co-operational specification between the applications in industrial control.One OPC DA server is implemented for the LonWorks network,which enables OPC clients to locally or remotely access this LonWorks network in an easy way.On the base of the discussion of the implementation principle of the server such as real time database,GUI,OPC objects and I/O read and write and so on,the key technologies such as processing write commands and synchronizing multi-threads are probed. |
