Introduction

In the process industry, safety instrumented systems used to perform safety instrumented functions have been used for many years: To enable the instrument to be used effectively for safety instrument functionality, and above all that instrument meets certain minimum standards and performance levels: GB/T 21109 describes the application of safety instrumented systems in the process industry: GB/T 21109 also emphasizes the need to implement a process hazard and Risk assessment (H Consider the contribution of other security systems: A safety instrumented system includes all equipment from sensors to final elements necessary to perform safety instrumented functions: GB/T 21109 intends to include the following parts: --- Part 1: Framework, definition, system, hardware and application programming requirements: The purpose is to present the specification, design, Installation, operation and maintenance requirements to ensure that the system enables the process to reach or maintain a safe state: --- Part 2: Application Guidelines for GB/T 21109:1-2022: The purpose is to provide according to the definition in GB/T 21109:1-2022 Guidelines for the specification, design, installation, operation and maintenance of safety instrumented functions and their associated safety instrumented systems: --- Part 3: Guidelines for determining the required safety integrity level: The purpose is to determine various methods for the safety integrity level of safety instrumented functions: GB/T 21109 contains two concepts as the basis of application: safety life cycle and safety integrity level: GB/T 21109 is aimed at safety instrumented systems based on the use of electrical (E)/electronic (E)/programmable electronic (PE) technology: in logical solution In the case of calculators using other technologies, the basic principles of GB/T 21109 need to be applied to ensure the fulfillment of functional safety requirements: GB/T 21109 It also covers sensors and final elements of safety instrumented systems, regardless of their technology: GB/T 21109 frame in GB/T 20438 The range of racks is dedicated to the process sector: In order to achieve the above minimum principles, GB/T 21109 proposes the method of SIS security life cycle activities: adopt this method so that the Use a sound and consistent technical strategy: In most cases, inherently safe process design can achieve safety well: But in some cases this is not possible or not practical: If necessary, one or more protective systems can also be combined to reduce the identified residual risks: Protection systems can rely on different Technology (chemical, mechanical, hydraulic, pneumatic, electrical, electronic, programmable electronics): To facilitate this method, G......
