| description | The utility model discloses a long distance controller for domestic electric appliances, which is characterized in that an automatic picking-up and time-delay hanging-up circuits connected in parallel to a telephone line are separately and mutually connected with a signal amplifying circuit and an audio signal prompting and answering circuit; the signal amplifying circuit is also mutually connected with a synchronous intermediate code electronic switching circuit, and is respectively connected to a unit digit decimal coding intermediate code circuit, a tens digit decimal coding intermediate code circuit and at least two groups of double audio intermediate code circuits via the synchronous intermediate code electronic switching circuit. The utility model enhances external cause interference resistant capability and the reliability of operating electric appliances for a long distance. |
