现代工业生产的大规模、复杂化,伴随自动化程度的提高,为了确保生产装置的安全运行,评价过程控制仪表和系统的可靠性具有看重要意义。本文介绍了可靠性计算理论,着眼于电动仪表的可靠性予测,提供具有参考价值的可靠性数据。并对提高仪表寿命和可靠性设计做了一定分析。最后扼要说明改善过程控制系统的可靠性,提高可用性的措施。
With the large-scale and complicated modern industrial production, with the increase of automation, in order to ensure the safe operation of the production plant, it is of great importance to evaluate the reliability of process control instruments and systems. This article describes the reliability calculation theory, focusing on the reliability of electric instruments to predict, provide a reliable reference data. And to improve the instrument life and reliability of the design made a certain analysis. Finally, a brief description of the process control system to improve the reliability and improve the availability of measures.
