Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention do not limit
In this.
As it is shown in figure 1, a kind of egg bracket automatic detection circuit, it includes at least two photoswitch list electricity
Road, described at least two photoswitch single circuit uses ranks form to connect formation egg bracket and automatically detects electricity
Road, the photoswitch luminous end supply pin of described photoswitch single circuit connects resistance R2, resistance R2 and connects electricity
Source positive pole, luminous end grounding leg connects power supply ground, and light-receiving end supply pin connects resistance R1, resistance R1 and connects row
Input, light-receiving end signal output part connecting triode Q1 base stage, the base stage of audion Q1 and transmitting interpolar
And connecting electric capacity C1, audion Q1 colelctor electrode connects row outfan.Preferably, described resistance R2 connects 5V electricity
Source positive pole.
Described photoswitch is by whether there is reflection infrared light to judge the presence or absence of testee, and photoswitch exports
End connects driving negater circuit, drives negater circuit to be connected with row outfan, row outfan output detections result
Signal, row input input detection original signal.Ranks assembled arrangement pressed by photoswitch, is in the photoelectricity of a line
Switch, its light-receiving end signal output pin is all connected to together, is then attached to drive the base stage of reverse audion,
Being in the photoswitch of same string, its light-receiving end supply pin all by connecting together after a resistance, then connects
Receive row input.Each row input sequentially inputs the high level of certain time, and the most adjacent two row letters
Number high level have certain interval in time.Master chip when row input input high level to outfan
Level carry out height judge, high level indicates that, without egg, low level indicates egg.
As in figure 2 it is shown, U101～U112 is 12 photoswitches in figure, Q101～Q103 is 3 drivings
Negater circuit, P10, P11, P12 are the row outfan of this circuit, and P20, P21, P22, P23 are this electricity
The row input on road.The circuit symbol of photoswitch such as Fig. 3,12 photoswitches use ranks form to connect,
P20～P23 connects the light-receiving end supply pin of every string photoswitch respectively, the light-receiving end letter of every a line photoswitch
Number output pin links together, and is connected to drive negater circuit input, is switching signal through drive amplification
After be re-fed into master chip I/O mouth.Photoswitch single circuit such as Fig. 1 of present invention design, wherein photoswitch is sent out
Light end supply pin connects resistance R2, resistance R2 and connects 5V positive source, and luminous end grounding leg connects power supply ground,
Light-receiving end supply pin connects resistance R1, resistance R1 and connects row input, and light-receiving end signal output part connects three poles
Pipe Q1 base stage, Q1BE interpolar also connects electric capacity C1, and Q1C pole connects row outfan.
During work, photoswitch all luminous ends supply pin connects 5V power supply, and all luminous end grounding legs connect power supply
Ground, makes photoswitch luminous end start to launch infrared light, and then master chip is followed successively by P20～P23 in order and carries
Confession high level, waveform such as Fig. 4 of corresponding four terminals, such as when P20 is high level, if U101 position
It is equipped with egg, then the light-receiving end of U101 can receive the infrared light reflected by egg surface, now U101
Light-receiving end turns on, and exports Continuity signal at light-receiving end signal output pin, and this voltage there are about 1.2V, then by this electricity
Pressure signal is sent into and is driven negater circuit, becomes 0V low-voltage feeding master chip input port P10 and carries out algorithm process
And judge that there is egg U101 position, if U105, U106 position does not has egg simultaneously, then U105, U106
Light-receiving end will not receive the infrared light of reflection, also would not turn on, and light-receiving end signal output pin will be for low electricity
Flat, low level becomes 5V high voltage feeding master chip after driving negater circuit reversely and carries out algorithm process and sentence
Disconnected U105, U106 position does not has egg.
Concrete judgement need to write algorithm routine in master chip, while P20 input high level, to P10,
P11, P12 carry out low and high level judgement, and low level is for there being egg, and high level is without egg, recognizable U101,
U105, U106 position, while P21 input high level, carries out low and high level to P10, P11, P12
Judge, recognizable U102, U107, U108 position, the like, can complete all photoswitch positions is
The no judgement having egg.For improving the accuracy and anti-interference judged, each output level of P20～P23
It is set as first exporting the circulation (such as Fig. 4) of high level 200ms output low level 1400ms again, so two
There is having between high level the interval of 200ms in column signal, can effectively avoid the crosstalk of two column signals and shadow
Ring the judgement of position.
If the row outfan of above-mentioned circuit is expanded to 10, row input expands to 10, we
The most practicable 20 the I/O mouths of method complete the detection of 100 egg positions.
