In the utility model, the applicant is exactly a characteristic of utilizing above-mentioned optoelectronic switch, uses it in the control of air-conditioning equipment, substitute traditional machine driving and touch screen technology, in certain cost control scope, reach easy to use, induction is sensitive, the control target that antijamming capability is strong.
Air-conditioning equipment described in the utility model comprises housing, heat exchange module, control module; Described control module comprises single-chip microcomputer and adjusting panel, and described adjusting panel includes a plurality of functional switches, and described functional switch is an optoelectronic switch.
As shown in Figure 3, be the control principle block diagram of air-conditioning equipment described in the utility model.Described control module comprises single-chip microcomputer (MCU), power circuit, temperature sensor circuit, draught fan control circuit, compressor Control Cprant, all kinds of holding circuit, infrared remote control and buzzer circuit, adjustment circuit and regulates panel; The horizontal electrical signal transmission of going forward side by side that links to each other with described single-chip microcomputer of described power circuit, temperature sensor circuit, draught fan control circuit, compressor Control Cprant, all kinds of holding circuit, infrared remote control and buzzer circuit; Described adjusting panel includes a plurality of functional switches (claiming function key again), as power switch key, mode key, wind speed key, timing key etc.; A plurality of functional switches on the described adjusting panel link to each other with described single-chip microcomputer by the adjustment circuit respectively and carry out signal of telecommunication transmission.
Embodiment one
As shown in Figure 4, be the adjustment circuit diagram of the utility model embodiment one.In the utility model, the applicant is reduced to diode with photoemitter, and receiver is reduced to a triode.In the present embodiment, described optoelectronic switch is the diffuse reflection type optoelectronic switch, it is a kind of sensor that integrates transmitter and receiver, when detection has operational motion, object reflexes to receiver with the light of the q.s of optoelectronic switch transmitter emission, so optoelectronic switch has just produced switching signal.
As shown in the figure, the receiver of the first resistance R c and optoelectronic switch---positive-negative-positive triode is connected and is formed a series arm, the transmitter of optoelectronic switch---diode is connected with the second resistance R s and is formed the road of an other series connection, above-mentioned then two series arm parallel connections insert power supply again, make described diode be in the forward conduction state; Simultaneously the emitter stage of a positive-negative-positive triode is inserted the positive pole of described power supply, the 3rd bigger resistance R L of resistance of the colelctor electrode of described positive-negative-positive triode series connection is inserted the negative pole of described power supply, insert in described base stage between the receiver of the first resistance R c and optoelectronic switch triode; Be connected to described single-chip microcomputer from drawing an output signal line between the colelctor electrode of the 3rd resistance R L and described positive-negative-positive triode in addition.In this circuit, described the 3rd resistance R L resistance is greater than the described first resistance R c resistance, and the described first resistance R c resistance is greater than the described second resistance R s resistance; And the first resistance R c resistance is about one of two percentages of the 3rd resistance R L resistance.The described first resistance R c is about about 5K, and the second resistance R s is about about 240, and the 3rd resistance R L is about about 1M.Described power supply is 5 volts, and minus earth.
In the utility model, described optoelectronic switch is selected the TCRT5000 photoemission sensor of VISHAY company for use, and it is a kind of sensor that integrates transmitter and receiver, and the end face of transmitter and receiver in the same way and be in same plane.This working sensor wavelength is 950mm, and induction highly is 12mm, and operating distance is 5mm, and the reflection radius is 22.5mm.From above-mentioned data we as can be seen, the working sensitivity of this kind functional switch is very high, working range also is special big.
The main effect of described adjustment circuit is to amplify the electric current that the optoelectronic switch receiver feeds back, so that detect feedback current; Through the amplification of this circuit, if sensor at the certain distance internal induction to object is arranged, the output of this circuit will be exported the 5V level.Use the I/O mouth just can detect, original SCM program is used hardly revised switching signal.
In the present embodiment, the output state of described optoelectronic switch is for often opening, i.e. the optoelectronic switch load of connecting since the output transistor of optoelectronic switch inside by and do not work, when having detected operational motion, transistor turns, load gets electric work.Can certainly be set to normally off.
Embodiment two
