Abstract (en)
[origin: US4801786A] PCT No. PCT/DE85/00176 Sec. 371 Date Jan. 24, 1986 Sec. 102(e) Date Jan. 24, 1986 PCT Filed May 21, 1985 PCT Pub. No. WO85/05712 PCT Pub. Date Dec. 19, 1985.A control system is provided having stationary check points which are contactlessly read by a data collector and verified. The data so read can be stored and transmitted by a transmitter to a central unit, where the data so received are centrally evaluated. Together with the data of the check point being read, the time at which the respective check point is read is transmitted to the central unit as well. If all data are received by the central unit, it transmits back a verification entry, and the data are subsequently stored in a memory together with such verification entry. If no verification entry is received, the data are automatically and continually retransmitted to the central unit until the verification entry is received by the receiver in the data collector. In addition, the data collector has a random generator capable of establishing which individual check points are to be successively called on by the security guard. Each check point is to be called on within a time range and, if such time limit is exceeded, an emergency call is automatically transmitted to the central unit.
