Often have numerous household electrical appliance in the Modern Family, intelligent appliance at first can be controlled the on/off of each electric appliances, for example, opens or closes a cover sound equipment, an air-conditioning; But, how can allow the sound equipment playing back music, perhaps allow air-conditioning regulate temperature? there are a lot of electric equipments to change in the family according to time, environment.For example, when owner was in, background music system should start, and should close at dead of night; Central air conditioner only should be in or start during by Long-distance Control owner; When window is opened, do not advise starting air-conditioning; These details original basic need owner manage in person, and in the automation appliance system, will be adjusted by a whole set of System of Logic in good time.This not only brings more facility, also can save the consumption of energy aspect to owner.

The control household electrical appliances of intelligence can also provide abundanter system relationship function.For example, when you prepared to see TV, parlor light was transferred to automatically that brightness (realizing by dimming controlling module), the curtain that you like pulled on (realizing by the curtain control module) automatically, televisor is opened and adjust to favorite channel.

The common implementation method of intelligent appliance is to increase an extra opertaing device for each household electrical appliances, just can carry out control by this device external opertaing device to household electrical appliances, this control mostly one to one at present, promptly an opertaing device can only be controlled household electrical appliances.

The utility model content

The purpose of this utility model provides a kind of infrared remote-controlled signal retransmission unit of suitable household electrical appliances Based Intelligent Control.

The purpose of this utility model is achieved through the following technical solutions: a kind of infrared transponder is characterized in that it comprises input interface unit, CPU (central processing unit) and infra red treatment unit; CPU (central processing unit) links to each other with the infra red treatment unit with input interface unit respectively.

The utility model can be converted to non-infrared control signal (as wireless remote control or line control signal etc. is arranged) infrared signal (changeing infrared signal but also do not get rid of infrared signal), can be used for that household electrical appliance and other are had the Based Intelligent Control of the equipment of infrared ray control function.

Embodiment

Describe specific embodiment of the utility model below with reference to the accompanying drawings in detail.

The utility model adopts the multiple Wireless/wired communication technology, singlechip technology and infrared ray control technology to realize the conversion of non-infrared control signal to infrared control signal.The structural design of this device as shown in drawings.

As shown in Figure 1, this device mainly is made up of input interface unit, CPU (central processing unit) and infra red treatment unit; The control signal that input interface unit transmits opertaing device is converted to digital signal and sends CPU (central processing unit) to; CPU (central processing unit) to the signal that input interface transmits analyze, processing and protocol conversion, remove to control infrared processing unit then; The infra red treatment unit sends/receives corresponding infrared control signal under the control of CPU (central processing unit), realize the various controls of household electrical appliance or carry out the study of telecontrol code.

One, input interface unit

Input interface unit comprises one or more interface units, interface mode is also varied, main interface unit has radio interface unit, power carrier interface unit, telephone line interface unit, GSM/SMS/GPRS interface unit etc., but also is not limited only to these interfaces.

1. radio receiving unit: be mainly used in the wireless remote control signal that receives ISM band, receiver module adopts superhet or superregeneration mode, and modulation system can be ASK, FSK, OOK etc., and carrier frequency can be 315MHz, 433MHz, 868MHz, 915MHz etc.

2. power carrier interface unit: this interface receives the control signal that transmits by line of electric force, can adopt multiple standards agreement (as agreements such as X-10, CEBUS), also can adopt self-defining agreement to realize.

3. telephone line interface unit: be connected with telephone network by telephone wire, to realize the Long-distance Control of phone.

4.GSM/SMS/GPRS interface unit: adopt the GSM/GPRS module, to realize control by note/wireless network;

In this example, adopted the power carrier receiving element as input interface unit.Its circuit theory diagrams are as shown in Figure 3: R6, C7, C17, L5, U2A and R7, C8, C18, L6, U2B form two frequency-selecting amplifiers respectively, the power line carrier signal of 120KHz is carried out frequency-selecting amplify; R17, U2C and R19, U2D form the common amplification of two-stage respectively; C16, C19 are two coupling capacitances.
