Introduction

Electro-sensitive protective equipment (ESPE) applies to machinery where there is a risk of personal injury, and it restores the machinery before people are placed in a dangerous situation to a safe state for protection. As a safety protection device for mechanical equipment, vision-based electro-sensitive protective equipment is related to the personal Personal safety and stable operation of mechanical equipment. This document provides design, manufacture of electro-sensitive protective equipment based on vision protective device (VBPD). It is of great significance to guide the design and production of electrosensitive protection equipment products in my country. GB/T 41997 consists of three parts constitute. --- Part 1.General technical requirements. The purpose is to establish general technical requirements for vision-based electro-sensitive protective equipment. --- Part 2.Particular requirements for visual protection devices using a reference model. The purpose is to establish a passive reference model as the background Special requirements for electro-sensitive protective equipment. --- Part 3.Special requirements for protective devices using stereo vision. The purpose is to establish electro-sensitive protective equipment based on stereo vision technology special requirements. The three parts of GB/T 41997 are matched together as an important part of the technical requirements and test methods for vision-based electro-sensitive protective equipment. Based on this, it promotes the improvement of the product performance and industry level of my country's electrosensitive protection equipment. Vision-based electro-sensitive protective equipment for mechanical and electrical safety Part 2.Vision with reference patterns Special requirements for protective devices

1 Scope

This document specifies the requirements for the design, manufacture and testing of electro-sensitive protective equipment (ESPE) using vision protective devices of the reference model, describing The sensitive function is the special requirements for electro-sensitive protective equipment using passive reference mode. This document is limited to the functionality of the ESPE and the way it interfaces with the machinery. Vision-based electro-sensitive protective equipment using reference patterns (VBPDPP) consists of a single image-sensitive device with a passive reference pattern as the background, and the detection principle is based on blocking or partially blocking mode of view. No information about object thickness, shape, surface features or position is required for detection. NOTE. This document does not cover multi-image sensor devices. This document applies to. ---Vision-based automatic ESPEs, which do not require human intervention; ---Vision-based automatic ESPEs to detect objects entering or existing in the detection area; ---VBPDPPs with a detection capability up to.200mm. This document does not apply to. ---Use VBPDs whose radiation wavelength exceeds 400nm~1500nm. This document does not cover. --- The size or configuration of the detection zone and its configuration in relation to any specific application of hazardous parts; --- Dangerous state of any machinery; --- Requirements for complex classification or differentiation of detected objects; --- Electromagnetic compatibility (EMC) emission requirements.
