4.2.2 SRSS performance class determination
In the chosen approach, using ISO 13482:2014 the required performance level of the safety functions of a Type 1.1 mobile robot is PL b, in accordance with ISO 13849-1:2015. The safety functions include the protective stop function, the safety-related speed control function, the hazardous collision avoidance function, and the travel surface detection function in accordance with ISO 13482:2014, which will be initiated by the SRSS.
The required performance class of the SRSS corresponding to PL b is the sensor performance class B specified in IEC TS 62998-1:2019.
4.2.3 SRS limits of use and SRSS function
The SRSS consists of three SRSs defined by the manufacturer as follows (see Figure 3).
1. SRSI: a 2D LiDAR suitable to be used up to PL b, in accordance with ISO 13849-1:2015, which allows the detection of persons and other safety-related objects and the measurement of their positions and velocities with high accuracy. The systematic capabilities are assessed in accordance with IEC TS 62998-1:2019. The sensing zone is up to a radius of 7 000 mm, and a viewing angle of 270°. The detection capability is given for safety-related objects with the properties: minimum size 40 mm x 40mm; minimum object reflectivity 5 %; maximum object speed 1 600 mm/s. The response time is 0,05 s. Use in indoor and outdoor environmental conditions is possible within defined limits.
2. SRS2: a TOF camera suitable to be used up to PL b, in accordance with ISO 13849-1:2015, which allows detecting parts of 3D volumes of persons, road surface, and other safetyrelated objects using 3D imaging technology. The systematic capabilities are assessed in accordance with IEC TS 62998-1:2019. SRS2 is capable of measuring the position and velocity of objects within the 3D sensor coordinate system. The sensing zone is up to 4 000 mm and vertical and horizontal field of views angle of 60° and 70°, respectively. The detection capability is given for safety-related objects with properties: minimum size 40 mm x 40 mm x 40 mm; minimum object reflectivity 5 %; maximum object speed 1 600 mm/s.
