Abstract: A functional safety system performs safety analysis on three-dimensional point cloud data measured by a time-of-flight (TOF) sensor that monitors a hazardous industrial area that includes an automation system. To reduce the amount of point cloud data to be analyzed for hazardous conditions, the safety system executes a real-time emulation of the automation system using a digital twin and live controller data read from an industrial controller that monitors and controls the automation system. The safety system generates simulated, or shadow, point cloud data based on the emulation and subtracts this simulate point cloud data from the measured point cloud data received from the TOF sensor. This removes portions of the point cloud data corresponding to known or expected elements within the monitored area. Any remaining entities detected in the reduced point cloud data can be further analyzed for safety concerns.

Abstract: A method for controlling discharging of a glass plate in a glass plate tempering technology process is provided. After a glass plate is fed into a heating furnace, a monitoring unit monitors and performs filtering on a working parameter of a heating element in real time, and then transmits the filtered working parameter to a control unit. The control unit compares the filtered working parameter with a specified threshold. After the working parameter reaches a maximum value or a minimum value, and then reaches the specified threshold during a subsequent change, the control unit sends an instruction to a drive mechanism. The drive mechanism acts to move the glass plate out of the heating furnace directly or after a time delay, so as to complete a glass plate heating process. The present disclosure changes a conventional time-based control method, reduces energy consumption, and improves quality of a tempered glass.
