Introduction

Safety-related sensors are mainly used in machinery and equipment where there is a risk of personal injury. Safety-related sensors enable machines to The sensor industry mainly uses general functional safety standards. GB/T 20438 (IEC 61508) series of standards, or mechanical standards in specific fields such as IEC 62061 and ISO 13849 series of standards as However, these standards do not provide guidance on how to avoid design failure or failure to detect faults under specific environmental conditions. GB /Z 44938 specifies the following requirements for sensors or sensor systems. Functional safety specifies the requirements for the systematic development and integration of sensors and sensor systems, filling the gap in specific sensor design standards. to identify gaps in systematic capability verification between the current standards and common functional safety standards for electrical, electronic and programmable electronic control systems. GB /Z 44938 is planned to consist of three parts. --- Part 1.Sensors used to protect personnel safety. The purpose is to improve the safety level of mechanical and electrical equipment in my country and ensure the safety of related The design, manufacture, and use of sensors that protect personnel safety are guided, and the personal safety of employees is standardized. Functional, safety and test requirements of sensors for personnel safety. --- Part 2.Application examples of sensors for protecting personnel safety. The purpose is to provide guidance and application for the use of Part 1 Example. --- Part 3.Sensor technology and algorithms. The purpose is to provide guidance on how to properly implement algorithms to prevent people from suffering intolerable risk. This document provides guidance and application examples for the use of GB /Z 44938.1 and is of great importance to the implementation of GB /Z 44938.1. significance. Electrical safety of machinery Part 2.Protection of persons Application examples of safe sensors

1 Scope
