GB/T 41997.2-2022Electrical safety of machinery—Vision based electro-sensitive protective equipment—Part 2: Particular requirements for devices using passive reference patterns (English PDF)

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.
