IEC TR 62998-2:2020 free download.Safety of machinery – Part 2: Examples of application.
Safety-related sensors are applied to machinery enting a risk of personal injury, They provide protection by causing the machine to revert to a safe condition before a person can be placed in a hazardous situation.
IEC TS 62998-1:2019 is intended for use by safety-related sensor manufacturers and integrators of safety-related sensors for the design of safety-related sensor systems used for the protection of persons.
This document gives guidance for manufacturers and integrators on the application of IEC TS 62998-1:2019.
This example covers the integration and installation phase using fusion of three SRSs into an SRSS in accordance with Clause 6 of EC TS 62998-1: 2019 to improve sensing zones an safety-related zones in accordance with requirements for the intended use. The intended uses are 2 different mobile robot types, in accordance with ISO 13482: 2014, that operate autonomously in a public area with limited access. The reader should be aware that th following descriptions are not based on comprehensive analysis and are only examples fo mobile robotics
Note:ISO 13482: 2014 covers mobile robots operating in an autonomous manner. For simplification, the term “mobile robot” will be used from now on.
Two different mobile robots operate on a certain university campus with buildings to achieve:
transport of in-house mail items among office buildings of the university, and
cleaning of pavements of the university
Figure 1 shows the typical outdoor pavement of a university campus. Person(s)being present or approaching the safety related zone(s) of an SRSS should be detected and the safety-related control system should initiate appropriate reaction of the mobile robot.
