초록 ▼

A communication device wherein leader pulses which continue for a predetermined time period are transmitted prior to the transmission of data from its transmitter; its receiver is rendered intermittently operative at a cycle shorter than half the continuation time of said leader pulses by means of a cycle operation controlling means to thereby become operative for a short time at a duty lower than 1/10; while the receiver is operating, it is detected by a detector means whether or not the leader pulses are transmitted; and when the transmission of the leader pulses is detected by the detector means, the receiver is kept operative for a predetermined time period by an operation holder means.

대표청구항 ▼

A communication device operated between a transmitter of a data signal and a receiver connectable to a power source, comprising: the transmitter transmitting a data signal consisting of a leader pulse which is continuous for a predetermined time period t1 followed by a series of data pulses provided within a predetermined duration; the receiver having receiving means for receiving the data signal from the transmitter, an intermittent pulse generator for generating a series of timed pulses spaced apart by a time period t2 and having a duty cycle of t3, an AND circuit having the data signal from the receiving means applied to one terminal and the timed pulses from the intermittent pulse generator applied to its other terminal and outputting a high level pulse when a timed pulse coincides with a leader pulse of the data signal, a trigger circuit for outputting an output pulse which is continuous for a time period t4 in response to receiving the high level pulse from the AND circuit, an OR circuit having the output pulse from said trigger circuit applied to one terminal and the timed pulses from the intermittent pulse generator applied to its other terminal and outputting a high level output when either of said timed pulses or said continuous output pulse is present, a power source circuit responsive to the high level output from said OR circuit for connecting power from the power source to said receiving means, and a data processing circuit for processing the data pulses of the data signal when said receiving means is connected by said power source circuit to an operating voltage of the power source when the continuous output pulse of time period t4 is provided by said trigger circuit, wherein t21/10 t2, t4 is long enough to receive all data pulses after detection of the leader pulse t1, whereby when no data signal is transmitted, the power source is connected to the receiver less than 1/10 the time over the timed pulses, and since t2 is shorter than ½the time period of the leader pulse, two or more timed pulses are generated during a leader pulse to ensure that the leader pulse will be reliably detected.
