机械安全电敏感防护设备第5部分:雷达防护装置的特殊要求

[中文适用范围]： 本部分IEC 61496对非接触式电敏感保护设备(ESPE)的设计、构造和测试提出了特殊要求，这些设备专门用于作为安全相关系统的一部分，提供对一个人或多人的全身检测，采用雷达保护装置(RPDs)通过频率调制连续波(FMCW)技术对雷达信号的漫反射进行感应功能。特别关注确保实现适当安全相关性能的特性。ESPE可以包括可选的安全相关功能，其要求在IEC 61496-1:2020的附录A和本文件的附录A中给出。本文件中的要求与工业制造环境中成人存在的检测相关。本文件未规定检测区域的尺寸或配置及其相对于任何特定应用的危险部分的布置，也未规定任何机器的危险状态。它仅限于ESPE的功能及其与机器的接口。本文件不考虑移动RPD应用的方面。如果RPD供应商指定RPD用于移动应用，可能需要额外考虑。如果RPD的设置不同于图2和图4，可能需要额外的要求和测试。本文件中所述的雷达截面基于水平布置的测量。如果本文件未包含所有必要的规定，则使用IEC TS 62998-1。对于本文件中未考虑的方面，也可以额外使用IEC TS 62998-1的规定。本文件不包括使用9 GHz至81 GHz范围以外的电磁辐射的RPDs(根据ITU无线电条例确定为频带10和频带11的子集)。对于使用此范围以外电磁辐射的感应设备，本文件可用作指南。国家法规可能限制可用频率。本文件可能与保护人员以外的应用相关，例如保护机器或产品免受机械损坏。在这些应用中，可能需要不同的要求，例如当感应功能要识别的材料具有与人不同的特性时。本文件不涉及与人员保护无关的ESPE功能的要求(例如使用感应单元数据进行导航)。虽然可以使用数据接口来控制可选的安全相关ESPE功能(附录A)，但本文件未提供具体要求。这些安全相关功能的要求可以通过咨询其他标准(例如IEC 61508、IEC 62046、IEC 62061和ISO 13849-1)来确定。本文件不涉及EMC发射要求。 [外文原描述]： IEC TS 61496-5:2023 provides particular requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to provide whole-body detection of a person or persons as part of a safety-related system, employing radar protective devices (RPDs) responsive to diffuse reflection of radar signals for the sensing function using frequency-modulated continuous-wave (FMCW) technique. Special attention is directed to features which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given in Annex A of IEC 61496-1:2020 and Annex A of this document. The requirements given in this document are related to the detection of adult persons being present in an industrial manufacturing environment. This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine. This document does not consider the aspects of a moving RPD application. Additional consideration can be necessary, if the RPD supplier specifies the RPD for use on moving application. Additional requirements and tests can apply if setup of the RPD differs from Figure 2 and Figure 4. Where this document does not contain all necessary provisions, IEC TS 62998-1 is used. For those aspects not considered in this document it is also possible to additionally use provisions from IEC TS 62998-1. Excluded from this document are RPDs that employ electromagnetic radiation outside the range 9 GHz to 81 GHz (identified as subset of band 10 and band 11 in accordance with ITU Radio Regulations). For sensing devices that employ electromagnetic radiation outside this range, this document can be used as a guide. National regulations can limit the available frequencies. This document can be relevant to applications other than those for the protection of persons, for example for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials to be recognized by the sensing function have different properties from those of persons. This document does not deal with requirements for ESPE functions not related to the protection of persons (e.g. using sensing unit data for navigation). While a data interface can be used to control optional safety-related ESPE functions (Annex A), this document does not provide specific requirements. Requirements for these safety-related functions can be determined by consulting other standards (for example, IEC 61508, IEC 62046, IEC 62061, and ISO 13849-1). This document does not deal with EMC emission requirements. The contents of the corrigendum of October 2023 have been included in this copy.
