SAFETY DEVICE FOR SECURING A HAZARDOUS AREA, METHOD FOR CONTROLLING A SAFETY DEVICE, COMPUTER PROGRAM PRODUCT, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

The invention relates to a safety device (10) for securing a hazardous area comprising at least one sensor grid (20) with a sensor arrangement (25), at least one transportation path (30) for transporting goods (5) with at least one optical sensor (35₁, 35₂, 35_n) for determining the position of the goods (5), and a control unit (100), which, during operation, is connected to the at least one optical sensor (35) and the sensor arrangement (25), the control unit (100) being designed to receive a first signal S₁ from the sensor arrangement (25) and to receive a second signal S₂ from the at least one optical sensor (35₁, 35₂, 35_n), the control unit 100 being designed to determine the occupancy B of the transportation path (30) depending on the first and the second signal S1, S2 and to provide a gating signal S₃ to control the sensor grid (20) depending on the occupancy B of the transportation path (30).
