标准范围

IEC 62682:2022规定了流程工业设施基于控制系统和人机界面(HMI)的报警系统管理的一般原则和流程。它涵盖了通过控制系统向操作员呈现的所有警报，其中包括来自基本过程控制系统、信号器、成套系统和安全仪表系统的警报。本文档中的实践适用于连续、间歇和离散过程。根据流程类型，满足特定需求的实现可能会有所不同。报警系统的主要功能是通知操作员异常过程条件或设备故障并支持响应。警报系统可以包括基本过程控制系统(BPCS)和安全仪表系统(SIS)，每个系统使用过程条件和逻辑的测量来生成警报。图1说明了通过报警系统的报警和响应数据流的概念。报警系统还包括用于经由HMI(通常是计算机屏幕或报警器)向操作者传达报警信息的机构。警报系统的附加功能是警报和事件日志、警报历史记录以及警报系统的性能度量的生成。有外部系统可以使用来自报警系统的数据。

IEC 62682:2022 specifies general principles and processes for the management of alarm systems based on controls system and human-machine interfaces (HMI) for facilities in the process industries. It covers all alarms to be presented to the operator through the control system, which includes alarms from basic process control systems, annunciators, packaged systems, and safety instrumented systems.
The practices in this document are applicable to continuous, batch, and discrete processes. There can be differences in implementation to meet the specific needs based on process type.
The primary function within the alarm system is to notify operators of abnormal process conditions or equipment malfunctions and support the response. The alarm systems can include both the basic process control system (BPCS) and the safety instrumented system (SIS), each of which uses measurements of process conditions and logic to generate alarms. Figure 1 illustrates the concepts of alarm and response dataflow through the alarm system. The alarm system also includes a mechanism for communicating the alarm information to the operator via an HMI, usually a computer screen or an annunciator. Additional functions of the alarm system are an alarm and event log, an alarm historian, and the generation of performance metrics for the alarm system. There are external systems that can use the data from the alarm system.
