  • Device and process for entering or leaving an area in a controlled manner
    Patent number: 7170406
    Abstract: A device system and a process for monitoring an industrial plant offers the persons working at the plant with the greatest possible protection. Signal transmitters (4, 5), which are fastened to persons (2, 3) or mobile objects, send or trigger a code related to a person or mobile object. Position marks (31, 32, 33, 34, 41, 42, 61, 62, 71, 72, 36, 37, 74), which provide a position code and a direction code for passing through an entrance or an exit, are arranged at entrances and exits of an industrial plant (21, 22). A receiving unit (15, 35, 43, 63, 73) receives the code of the signal transmitters combined with the position code and direction code. A computing and evaluating unit (12) is connected with the receiving unit and generates a topology for the persons or mobile objects to enter or leave the industrial plant.
