2000年世界上工控机市场估计为300～400亿美元,其中DCS 60亿美元,嵌入式系统60～70亿美元,FCS 20～30亿美元,IPC 70～80亿美元,PLC70～80亿美元,数控70～80亿美元。并且每年以10％～15％的速度增长。 1.DCS(集散控制系统)的发展趋势 虽然以现场总线为基础的FCS发展很快,并将最终取代传统的DCS,但FCS发展有很多工作要做,如统一标准,仪表智能化等。另外传统控制系统的维护和改造还需要DCS,因此FCS完
In 2000, the industrial IPC market in the world was estimated to be 300 to 40 billion U.S. dollars, including 6 billion U.S. dollars for DCS, 60 to 7 billion U.S. dollars for embedded systems, 200 to 3 billion U.S. dollars for FCS, 70 to 80 billion U.S. dollars for IPC, and 70 to 80 billion U.S. dollars for PLC. CNC 70 to 8 billion US dollars. And it grows at a rate of 10% to 15% every year. 1. Development trend of DCS (Distributed Control System) Although FCS based on field bus has developed rapidly and will eventually replace the traditional DCS, there is a lot of work to be done in the development of FCS, such as unified standards and intelligent instrumentation. In addition, DCS is needed for the maintenance and reconstruction of traditional control systems, so FCS is completed.
