When the experiment is in progress, the three-dimensional roaming screen uses arrows and footprints to prompt the user to move to the experimental location. The circle around the mechanical object shows the working radius. The experimental process is accompanied by a dialog box reminder of the three-dimensional robot. The content is as follows:
A. The mechanical safety distance experiment includes the safety distance experiment to prevent the upper and lower limbs from touching the danger zone (divided into 2 fence heights and opening sizes). After selecting to enter, GB23821-2009 "Mechanical Safety to Prevent Upper and Lower Limbs from Touching" pops up in front of the camera. "Safe Distance in Danger Zone" requirements, error demonstration: The experimental process is that after the human body enters the working radius of the mechanical object and is injured, the red screen and voice prompts that the human body has received the mechanical injury, and returns to the original position and conducts the next experiment. The final step is the correct approach. .
B. Mechanical safety protection device experiments are divided into safety interlock switches, safety light curt*ns, safety mats, safety laser scanners and other protection device experiments. Optional categories (safety input, safety control, safety output, others), manufacturers, products List (safety interlock switch, safety light curt*n, safety mat, safety laser scanner, safety controller, safety relay, safety guardr*l).
