Abstract

An electronic locking arrangement comprising a lock unit (17) and a key unit (19) is proposed. Each of the units has a control circuit (35, 41) and a transmitting and receiving circuit (33, 47, 39, 43) which transmit information signals inductively via coupling coils (21, 23) to the control circuit (35, 41) of the other particular unit. The transmitting and receiving circuit of the lock unit (17) has an amplitude modulator (33) and a frequency demodulator (47) for the transmission of the information signals, whilst the transmitting and receiving circuit of the key unit (19) comprises a frequency modulator (43) and an amplitude demodulator (39). In dependence on the information signals transmitted between the units (17, 19), the control circuit (35) of the lock unit (17) generates a control signal representing the locking state. The transmission of the information signals takes place via a single pair of coupling coils (21, 23) utilised in both transmission directions. The amplitude modulator (33) modulates the high-frequency signal of a free-running high-frequency oscillator (27), the frequency-determining circuit of which comprises the coupling coil (21) of the lock unit, whilst the amplitude demodulator (39) is connected to the coupling coil (23) of the key unit (19). The frequency modulator (43) is likewise connected to the coupling coil (23) of the key unit (19) and detunes the frequency-determining circuit of the high-frequency oscillator (27) in dependence on the information signal to be transmitted. The frequency demodulator (47) is also coupled to the high-frequency oscillator (27). The locking arrangement permits high locking security, along with a high data transmission rate, at a comparatively low outlay in terms of structural parts. <IMAGE>
