Abstract (en)
[origin: EP0437757A2] In the device for monitoring a corridor (1), the corridor (1) is provided, for the purpose of establishing the number and the direction of passage of the individual persons or objects passing along the corridor (1), with a plurality of sensors and authorisation monitoring devices (21, 22), whose signals are detected by an evaluation and security unit, and fed to a control device. In order to avoid erroneous signals, and so that the monitoring device can manage with only one scanning device (13) and with a relatively simple evaluation electronics system operating with a higher reliability, there is arranged in each case in the direction of passage (arrow 35) in front of and behind a scanning zone (Z2), which is defined by two horizontal light barriers (LS1, LS2) and has a passive IR sensor (14), an optical scanner (LT1, LT2) whose signals are used to determine the direction of passage, to activate the scanning device (13), and together with the signals of the scanning device (13) to generate an activating or recording or clearance signal or an alarm or error signal. Moreover, a time control device is provided which checks the temporal sequence of the various signals and, if required, maintains the clearance of the corridor (1) or effects its closure. <IMAGE>
