Abstract

A remote telephone controller belongs to the technical field of household appliance control apparatus. An acoustic signal collection module sends a collected acoustic simulation signal to a signal amplification module, the amplified acoustic simulation signal is converted into a digital signal via an A/D conversion module, a signal judgment processing unit judges the received digital signal and then outputs switch-on and switch-off of a signal control switch module. The utility model with simple structure does not need to modification for the telephone and only needs to placing the remote telephone controller aside to collect telephone rings, which can realize remote control for air-conditioner, lamps, electronic rice cooker and other household appliances, such as opening in advance the air-conditioner in the living room to enjoy cool ambience once returning home, and causing false appearance that somebody is at home by opening and closing lamps and television in the living room via the system when the user is in tour or in business outside, thus improving safety of the home. In addition, the system can also be applied to industry and agriculture to accomplish remote control for unmanned positions.

Description

The remote phone controller

Technical field

The utility model belongs to the technical field of household electrical appliance control appliance, is specifically related to a kind of remote phone controller.

Background technology

Along with the development of society and the raising of people's living standard, increasing household electrical appliance have entered people's life, and these household electrical appliance bring a lot of convenience for people's life and enjoy.But in the present city, most crowd is man and wife working clan, therefore situation about often facing is the winter in cold, go back home start heating installation after family just slowly warm, in the summer of sweltering heat, get back in the scorching family and just to begin slowly to freeze after opening air-conditioning,, then can become thief's object unavoidably for some rooms on business trips and uninhabited for a long time.Along with phone universal use in the family, utilizing phone that household electrical appliance are carried out Long-distance Control is the development in future direction.The product of existing telephone remote control home electrical appliance aspect all needs phone is reequiped in the market, or has utilized telephone network and necessary agreement through Virtual network operator, improve production cost of products and consumer's use cost like this.

The utility model content

At problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of remote phone controller, is placed on the other telephone ringer sound of collecting of telephone set, can make judgement household electrical appliance are controlled.

Described remote phone controller, it is characterized in that the sound signal collecting module sends to the signal amplification module with the speech simulation signal that collects, speech simulation signal after the amplification is converted to digital signal through the A/D modular converter, and the break-make of back output signal control switch module is judged in signal judgment processing unit to the digital signal that receives.

Described remote phone controller is characterized in that signal judgment processing unit is connected the transmission of carrying out signal with the signal monitoring unit.

Described remote phone controller is characterized in that 4 pairs of speech simulation signals of capacitor C carry out filtering in the described signal amplification module, and the voltage amplifier circuit of forming through resistance R 7, R8, R9 and voltage amplification chip U2 amplifies the speech simulation signal then.

Described remote phone controller is characterized in that the switch module input is provided with current-limiting resistance, and the current-limiting resistance other end connects the base stage of triode, the grounded collector of triode, and emitter is connected to the negative pole of relay.

Described remote phone controller is characterized in that signal judgment processing unit connects one road or one road above switch module.

Described remote phone controller is characterized in that signal judgment processing unit adopts single-chip microcomputer that digital signal is handled.

The utility model is simple in structure, do not need telephone set is reequiped, only need place this remote phone controller aside, collect the telephone ringer sound, can realize Long-distance Control domestic electric appliances such as air-conditioning, electric light, electric cookers, as can in advance the air-conditioning in room being opened, enjoy world of coolness once entering the door, when user's out on tours or when going on business, by electric light, the TV in native system switch room, the illusion that causes the someone to be in improves household safety.In addition, native system also can be applicable in the industrial or agricultural, realizes the Long-distance Control to the unattended operation post.

Embodiment

The user dials the landline telephone in the family, sound signal collecting module 1 usefulness sound transducer is collected telephone bell and is translated into the signal of telecommunication that circuit can be discerned, then the speech simulation signal that collects is sent to signal amplification module 2,4 pairs of speech simulation signals of capacitor C carry out filtering in the signal amplification module 3, the voltage amplifier circuit of forming through resistance R 7, R8, R9 and voltage amplification chip U2 amplifies the speech simulation signal then, and voltage amplification chip U2 adopts LM339 in the present embodiment.Speech simulation signal after the amplification is converted to digital signal through A/D modular converter 3, adopts a gate circuit among the Schmidt trigger 74LS132 that the speech simulation signal is carried out the A/D conversion here.The 4 pairs of digital signals that receive in signal judgment processing unit are judged the break-make of back output signal control switch module 5, and signal judgment processing unit 4 adopts single-chip microcomputer that digital signal is handled, and the single-chip microcomputer U4 of Cai Yonging is 85C51 here.Signal judgment processing unit 4 is connected the transmission of carrying out signal with signal monitoring unit 6, and signal monitoring unit 6 is a watchdog circuit, can make CPU fly to enter the state normal program circuit from endless loop and bullet.Switch module 5 inputs are provided with current-limiting resistance, and the current-limiting resistance other end connects the base stage of triode, the grounded collector of triode, and emitter is connected to the negative pole of relay.

The single-chip microcomputer of signal judgment processing unit 4 is to encoding digital signals, desired signal is distinguished and judged whether to be in the decoding back with gating circuit, the break-make of triode in the control switch module 5 then, the attaching plug of each electrical equipment is received on the relay, the on/off of relay control high-tension electricity is realized the control to household electrical appliances.Adopt the program of being compiled in the single-chip microcomputer to control to the signal judgment processing procedure, this software is not in the protection range of this patent, so do not describe in detail.Signal judgment processing unit 4 connects one road or one road above switch module 5.
