Data transmission system to prohibit unauthorized operation of e.g. a vehicle lock, has encoder that combines time stamp signal with transmitter identification number and information data to form encoded data signal

摘要

The system has at least one time measurement device (5,8), encoder and decoder devices (10,11) and at least one evaluation unit (AE) for outputting a control signal. An encoder in the transmitter and receiver devices (2,3) combines a time stamp signal with an identification number for identifying the transmitter and information data to form an encoded data signal and transmits encoded electronic data when the transmitter is activated.
