摘要
随着电子安全监控系统(PES)的日益广泛应用,其系统自身的安全保护已成为安全科技最前沿的问题之一。本文论述了PES在安全系统中的主要应用领域,分析了PES出现故障和失误的原因主要分为硬件故障、系统失误和管理缺陷三大类,提出了建立PES安全保护系统的技术路线和提高系统可靠性的技术措施。建议我国从标准化的角度深入开展电子安全监控系统的安全性研究。
With increasingly widespread application of safety monitoring programmable electronic system （PES）, safety of the system has become one of the most advancing front subjects of safety science and technology. In this paper, main applied fields of PES in safety system, namely in process detection, monitoring and early - warning system, chemicals transport monitoring system, major accidents prevention, monitoring and emergency response support system, are expounded. Based on analyzing the reason and its type of system fault and failure of PES, both technical route of building safety protect system and technical measures of improving its reliability of it are given. The author suggests that our country should profoundly develop safety research of electronic safety monitoring system on the point of standardization.
