Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To transmit data with high reliability even when data are interfered with an external disturbance by using a plurality of different carrier frequencies so as to send the same transmission data in the remote control communication equipment superimposing the transmission data onto the carriers and sending the resulting data. SOLUTION: The equipment uses a carrier Cr on which two different frequencies f1, f2 are superimposed, a signal detection circuit 4 has carrier frequency decision circuits 5a, 5b to designate the two frequencies f1, f2. In the case of demodulation, the carrier is demodulated, based on the detection frequencies f1, f2 instructed by a microcomputer 3. A microcomputer 3 of a transmitter side (heat source device 2) outputs the carrier Cr on which the two different frequencies f1, f2 are superimposed. The carrier is amplitude-modulated, based on a data output pour at the signal detection circuit 4 and the resulting data are sent to a receiver side as transmission data SD in which same data are simultaneously in existence.  The receiver side discriminates the respective detection frequencies and demodulates the data and the demodulated data are given to a microcomputer 3 as data input DIN, then the redundancy of the data is high.
