核电厂安全级DCS平台网关通信机制的研究
|
摘要
在核电领域, DCS (分布式控制系统)发展迅猛,作为核反应堆安全运行的重要保障设备,负责执行紧急停堆、事故后监测等重要功能,完成这些功能需要DCS系统安全设备和非安全设备之间相互配合。网关站负责在安全设备和非安全设备之间建立起通信关系,将安全设备侧的安全数据进行转换并发送到非安全设备侧。文章设计了安全级DCS平台侧网关站的架构以及通信机制。
In the field of nuclear power, DCS develops rapidly. As an important safeguard equipment for safe operation of nuclear reactor, it is responsible for emergency shutdown, post-accident monitoring and other important functions. To accomplish these functions, DCS system security equipment and non-security equipment need to cooperate with each other. Gateway station is responsible for establishing communication relationship between security equipment and non-security equipment, converting security data form security equipment side to non-security equipment side and sending them to non-security equipment side. This paper designs the architecture and communication mechanism of security level DCS platform side gateway station.
