数字化仪表和控制系统已在核电厂安全系统领域内得到应用,网络通信功能是数字化仪控设备必不可少的。如何设计接口卡使得同时满足现场总线通信要求和核电安全级要求,是研制数字化仪控设备时必须解决的一个重要问题。本文介绍了如何把各种标准和导则提出的安全设计准则和安全要求应用在核级现场总线接口卡的软硬件开发上,具体描述了如何遵循验证和确认过程来保证可靠性。
Digital instrumentation and control systems have been used in nuclear power plant safety systems and network communications functions are essential for digital instrumentation. How to design an interface card to meet the requirements of field bus communication and nuclear safety at the same time is an important issue that must be solved when developing digital instrumentation and control equipment. This article describes how to apply the safety design guidelines and safety requirements presented by various standards and guidelines to hardware and software development of nuclear fieldbus interface cards and details how to follow the verification and validation process to ensure reliability.
