More Information
Summary:The utility model relates to a far-end remote control device which uses a telephone calling number as a passing cipher and comprises a power supply circuit, a telephone receiver taking up and detecting circuit, a DTMF/FSK signal decoding circuit, a storing circuit, a program processing unit and an outputting and driving circuit. The output ends of the telephone receiver taking up and detecting circuit and the DTMF/FSK signal decoding circuit are respectively connected with the input end of the program processing unit, and the output end of the program processing unit is connected with the input end of the outputting and driving circuit. The program processing unit is also connected with the storing circuit, and the DTMF/FSK signal decoding circuit is connected with the telephone receiver taking up and detecting circuit. The telephone calling number is used as the input of the passing cipher to make operation and use more convenient.
