| 摘要: |
| 对两异构系统间数据通信提出了一种网关的设计方法，以实现美国西屋Ovation系统与法国Alstom T20控制系统间的数据通信。通过截取终端数据包的方法实现网关机与T20控制器的通信，采用标准的Modbus协议实现网关机与Ovation的通信。所阐述的方法对具有相似问题的老工业系统具有一定的参考意义。 |

| Abstract: |
| A design of the gateway between two isomer systems is brought forward to implement the data communication between DCS ( Distributed Control System )( Ovation of Westinghouse USA ) and T20 ( control system of Alstom ,France ) .The communication between the gateway and T20control system is implemented by intercepting the terminal data ,while the communication between the gateway and Ovation DCS is implemented with standard Modbus protocol.The method introduced may be referred in the retrofitting of old industrial systems. |
| Key words: T20system,Ovation system,Modbus protocol,isomer system, |
