摘要
从集散控制系统(DCS)的网络通信、硬件配置和软件结构三个方面,采用对比分析方法,对Symphony和Teleperm-XP系统的功能进行了分析,给出了分析结果。两者均为四层网络系统,网络通信协议不同,但对应层的功能基本上相同;两者的硬件配置均为积木式结构,且一一对应,各有特色;两者采用不同的操作系统,但软件结构设计方法相同。
The System functions of symphony as contrasted with Teleperm-XP are analyzed in three way of network communication,hardware and software composition of distributed control system.The analysis conclusions are given.Both of the systems are four gradation networks.Although the protocol of the network communication is different,the functions of the corresponding network gradation are basically the same.
