Description of drawings

Fig. 1 is the remote control system of household electrical appliance structured flowchart;

Fig. 2 is the structured flowchart of the invention remote control device for household electric appliances;

Embodiment

Such as Fig. 1, a complete remote control system of household electrical appliance comprises four ingredients, the one, and widely distributed, resourceful information network is such as the information platform that is provided by mobile or UNICOM; The 2nd, engine control system; The 3rd, several minutes control system; The 4th, the remote controlled communication terminal is such as electric cooker, micro-wave oven and air-conditioning etc.The remote controlled communication terminal links to each other with system host by telephone communication network, system host carries out data transmission and communicates by letter with minute control system by wireless mode, do not need direct line between master control system and minute control system, can avoid at house wiring.

In conjunction with Fig. 2, system host mainly is comprised of master controller, ring detection module, dislodging machine control module, DTMF decoding circuit, voice recording-reproducing assembly, data transmit circuit, long time no operations automatic hand-up circuit and interlock circuit thereof etc.Minute control system mainly is comprised of system's slave and each household electrical appliance, and system's slave main circuit will be comprised of data receiver and decoding circuit, driving circuit, indicating circuit etc.

Wherein, dislodging machine control module adopts HK400F type miniature relay, the ring detection module is formed by connecting by optocoupler 4n25 and schmitt inverter 74HC14, the DTMF decoding circuit adopts dtmf signal decoding chip MT8870, voice recording-reproducing assembly adopts monolithic voice recording and playback ic ISD25120, master controller adopts AT89S51 type single-chip microcomputer, and the output signal circuit adopts VD5026 and the VD5027 that can carry out wireless connections.

When the ringdown that has by the PSTN/PLMN incoming end, the ring detection module that is formed by connecting by optocoupler 4n25 and schmitt inverter 74HC14 can detect ringdown, then be input to master controller AT89S51 detecting the result, the ringdown number of master controller AT89S51 statistics input, after the quantity that reaches setting, send a signal to monolithic voice recording and playback ic ISD25120, play the voice signal of appointment to the PSTN/PLMN incoming end, thereby the prompting side of being sown into operates according to voice suggestion.Master controller AT89S51 gives dislodging machine control module signal simultaneously, open HK400F type miniature relay, thereby connect the input of PSTN/PLMN incoming end and dtmf signal decoding chip MT8870, when being sown into root and according to voice suggestion button operation being arranged, key information is decoded by dtmf signal decoding chip MT8870, decoded result is input to master controller AT89S51, master controller AT89S51 is according to decoded result, send again different signals, if enter the key information of next stage menu, then control the information of voice prompt that monolithic voice recording and playback ic ISD25120 plays the next stage menu, if the key information of actuating equipment operation, then master controller AT89S51 transmits a signal to VD5026, then arrive VD5027 by transmission of wireless signals, VD5027 opens or closes according to equipment corresponding to signal controlling, and then master controller AT89S51 transmits control signal to monolithic voice recording and playback ic ISD25120 again, and the prompting side of being sown into does further operation again.
