Abstract
The utility model relates to a remote controller for household electrical apparatuses, which is composed of a telephone ringing detection circuit, a double voice frequency transceiver circuit, a single-chip microcomputer, a driving circuit and a control relay, wherein the output end of the telephone ringing detection circuit is connected with the output end of the double voice frequency transceiver circuit, the input end of the double voice frequency transceiver circuit is connected with the interrupt input end of the single-chip microcomputer, the control signal output end of the single-chip microcomputer is connected with the input end of the driving circuit, and the output end of the driving circuit is connected with a control relay. After the scheme is adopted, people can utilize telephone sets to send out control instructions to the utility model, after the single-chip microcomputer receives the corresponding instructions, definite control signals are output, the relay for controlling the corresponding electrical apparatuses is switched on and switched off, and accordingly, the utility model achieves the purpose that the telephone set is used for the remote control to the household electrical apparatuses.
Description
Technical field
The utility model relates to a kind of control device, particularly relates to a kind of device that utilizes telephone set that household electrical appliance are controlled.
Technical background
Raising along with people's living standard, various household electrical appliance such as refrigerator, washing machine, electric cooker are more and more universal, bring convenience and enjoyment to daily life, but the control of various household electrical appliance must rely on people's execute-in-place, and before can going home meal is boiled earlier, can air-conditioning be opened earlier, the meal of family has also been carried out after going back like this, the room is also pleasantly cool, and this is people's pursuit always.At present also not to the remote control of household electrical appliance.
Summary of the invention
The purpose of this utility model provides a kind of control device that can carry out Long-distance Control by telephone set to household electrical appliance.
For achieving the above object, the utility model adopts following technical scheme: a kind of household electrical appliance remote control, transmission circuit, single-chip microcomputer, drive circuit and control relay are formed frequently by phone ringing testing circuit, double-tone for it, the output termination double-tone of phone ringing testing circuit is the output of transmission circuit frequently, the input of double-tone frequency transmission circuit connects the interrupting input end of single-chip microcomputer, the control signal output ends of single-chip microcomputer connects the drive circuit input, drive circuit output termination control relay.
Described double-tone transmission circuit frequently is a double-tone transceiver IC 8888 frequently.
Described drive circuit is a drive integrated circult 2803.
Described single-chip microcomputer is 89c52.
After adopting such scheme, people just can utilize telephone set to send control command to the utility model, and single-chip microcomputer is exported certain control signal after receiving command adapted thereto, the relay of control corresponding electric appliance is opened and closed, thereby realized utilizing telephone set household electrical appliance to be carried out the purpose of Long-distance Control.
Description of drawings
Accompanying drawing is depicted as circuit theory schematic diagram of the present utility model.
Embodiment
The household electrical appliance remote control is by phone ringing testing circuit DET, double-tone is transceiver IC 8888 frequently, single-chip microcomputer 89c52, drive integrated circult 2803 and control relay J1～J4 forms, the output termination double-tone of telephone bell polarization circuit is the output of transceiver IC 8888 frequently, the output of double-tone frequency transceiver IC meets the interrupting input end INT0 of single-chip microcomputer 89c52, the control signal of single-chip microcomputer 89c52 is connect the input of drive integrated circult 2803 by the output of P1 mouth, the output termination control relay J1～J4 of drive integrated circult 2803, the switch contact of relay J 1～J4 is connected in the supply socket of different household electrical appliance.According to the quantity of household electrical appliance, control relay can also be more than 4.The existing in the prior art ripe circuit of telephone bell polarization circuit, the utility model no longer discloses its physical circuit schematic diagram.The peripheral clock circuit of single-chip microcomputer, reset circuit etc. also no longer provide.
People can be in the middle of going out or going to work, telephone set is made a phone call in family, the phone ringing testing circuit is after detecting bell signal, convert audio signal to digital signal input single-chip microcomputer by double-tone frequency transceiver IC 8888, single-chip microcomputer is handled the signal of receiving, and exports control signal from the respective end of P1 mouth, this control signal is through the amplification of drive integrated circult 2803, drive corresponding relays and move, open the power supply of corresponding electric appliance socket, this electrical equipment is started working.
