Abstract为发展我国自主知识产权的安全控制技术,开发国内首个经第三方认证的安全相关产品,给出了功能安全温度变送器的设计方法和可靠性分析方法。依据IEC61508功能安全标准,结合安全温度变送器1oo1D的结构特点,研究了变送器自诊断的实现方法,同时建立了Markov模型,并对变送器的可靠性进行了定量评估。分析结果表明,安全温度变送器满足功能安全要求和安全完整性等级要求。
Other AbstractTo develop the safety control technology with our own intellectual property, and develop the first safety related product authenticated by the third-party certification, the design and reliability analysis methods of the functional safety temperature transmitter are given. In accordance with the IEC 61508 functional safety standard, and combining the features of functional safety temperature transmitter with lool D architecture, the implementing method of self-diagnostics for the transmitter is researched. In addition, the Markov model is established to quantitatively assess the reliability of transmitter. The results of analysis show that the temperature transmitter meets the requirements of functional safety and safety integration level.
