Abstract:
An electronic safety system, comprising:a plurality of safety units having control devices associated therewith and being adapted to be arranged on an object to be secured; at least one authorizing authentication element; and a plurality of authentication element detection sensors, each having a signal sending device for emitting a query data signal within a corresponding acquisition range, which query data can be received by an authentication element situated in the corresponding acquisition range, the authentication element having devices for returning an authentication response signal; wherein query data signals emitted by the authentication element detection sensors contain a data protocol field coded with sensor-specific identification information; and each authentication element has devices for analyzing the data protocol field of received query data signals coded with sensor-specific identification information, and for generating an authentication response signal which contains a sensor-indicative data protocol field that can be analyzed by the control devices, which data protocol field is coded with information that identifies each detection sensor from which the authentication element has received a query data signal.
