Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model example is carried out clear Chu, it is fully described by.

Refer to Fig. 1-3, a kind of household electrical appliance remote control based on PSTN, including telephone wire, single-chip microcomputer U1, chip U2, ring detection and simulation dislodging machine module, MTMF decoding circuits, voice recording-reproducing assembly, speech control module and centralized Control Module；The telephone wire connection ring detection and simulation dislodging machine modular circuit, ring detection and simulation dislodging machine modular circuit Connect single-chip microcomputer；The telephone wire connects DTMF decoder module circuits, DTMF decoder modules circuit connection single-chip microcomputer；The monolithic Machine connects voice control module circuit, voice control module circuit connection voice recording-reproducing assembly circuit connection telephone wire and ring inspection Survey and simulation dislodging machine modular circuit；The voice cue module circuit, is that the multistage voice selecting order that user prestores connects Continued broadcasting is put, and word, morpheme are combined into a word, even one section words plays back；The single-chip microcomputer is the core system processor； The single-chip microcomputer connects Centralized Controller；U1 chip models are STC89C51, and U2 chip models are ISD1402.

Operation principle of the present utility model is：Fig. 1-3 are referred to, household electrical appliance of the utility model based on PSTN are remotely controlled System, main control module is constituted by single-chip microcomputer, carries out main information processing, is received peripheral operation and is instructed to form various control signals, And completion is for the record of various information；When needing remote control home appliance, corresponding telephone number, ring detecting circuit are dialed Ringing signal is detected, if before someone receives calls 6 times, the use to program controlled telephone is not impacted, when ringing number reaches To after 6 times, single-chip microcomputer starts voice warning circuit and sends prompt tone, asks whether to enter home wiring control pattern, it is no to press " 0 " key, On-hook is exited, and pressing " 1 " key is, electromechanical road automatic off-hook of seting out enters state of a control and off hook signal is input in single-chip microcomputer, Single-chip microcomputer is received after off hook signal, is started voice warning circuit and is sent prompt tone, is pointed out operator's input password or is exited, The password of input is received through DTMF, is converted into binary number and is compared with the password being previously stored in single-chip microcomputer, if not phase Symbol, then voice message code error, can be re-entered again, and prompt tone and automatic hand-up are sent out if three code errors；If Password is consistent then voice message selection control passage, after channel selecting, presses " 1 " key and represents to open the road electrical equipment, and have voice Point out " the road electrical equipment has been switched on ", press " 0 " key and represent to turn off the road electrical equipment have prompt tone " the road electrical equipment has been switched off ", Press " * " key then can on-hook exit, if time-out if automatic hand-up.
