The principle of device detection object height based on the circuit is as follows:
The port P1 control triode Q1 conducting of processor 20, so that infrared emission head LED1 to LED5 emits infrared light,
Wherein the analog-to-digital conversion port AD2 of processor 20 receives the first voltage signal of infrared receiving terminal RE5 output, the first voltage
Signal is the size of received infrared emission head LED5 transmitting and the infrared light through object reflection.Mould of the processor 20 inside
Number conversion circuit, is converted into the first numerical value for voltage analog signal, the horizontal distance of detection device and object is determined with this.
It is found through experiments that, the linear inverse relation of horizontal distance of the signal magnitude, that is, luminous intensity and object of light, i.e. L=
K/X1, wherein L is horizontal distance, and X1 is the luminous intensity that infrared receiving terminal RE5 is received, i.e. processor 20 passes through analog-to-digital conversion end
The first numerical value that mouth AD2 is obtained, the relationship of the two are as shown in Figure 7.K value is a fixed constant, passes through the experiment of early period
Sample information can determine K value, thus substituting into above-mentioned formula again can facilitate determination to obtain horizontal distance L.
The voltage signal that infrared receiving terminal RE1 to RE4 is exported is connected in parallel to the modulus of processor 20 through resistance R1 to R4 respectively
Conversion port AD1, so that the voltage signal of each infrared receiving terminal output among these is converted into electric current and is incorporated to analog-to-digital conversion end
Mouth AD1, and through being converted into voltage signal with the analog-to-digital conversion port AD1 internal schema conversion circuit connecting, reconvert is at second
Numerical value.Therefore second value is the cumulative of the voltage signal of every road infrared receiving terminal output.Namely second value is that every road is infrared
Receive the summation of a received light intensity signal.
It is found through experiments that in the case that the horizontal distance L of detection device and object is fixed, second value, that is, above-mentioned light
The summation of intensity and the height linear proportional relationship of object, when object is higher, what the infrared emission head that can be reflected back emitted
Infrared signal is more, then the summation of the luminous intensity received is bigger, otherwise smaller.Consider further that detection device and object it is horizontal away from
After L, the relationship between the height and second value of object is as shown in Figure 8.
The relationship of object height and second value when wherein L1 and L2 is different horizontal distance, wherein L1 < L2, that is, examine
When measurement equipment and object are closer, summation, that is, second value of luminous intensity is bigger.
It is easy to get according to the relation curve of this three in Fig. 8 to following formula of computed altitude:
H=AX2+L；
Wherein H is the height of object, and L is horizontal distance, and X2 is second value, and A value is a fixed constant, by preceding
The sample information of the experiment of phase can determine A value, finally obtain by the calculation formula substitution of above-mentioned L:
H=AX2+K/X1；
Since A and K are specific constant, only it needs to be determined that the first numerical value X1 and second value X2 of luminous intensity are
The height H of countable entity body.Since calculation formula is relatively easy, because of the computing resource without occupying processor 20, thus locate
The processor 20 that device 20 can be weak using the computing capability of low cost is managed, the cost of whole device is reduced with this.

So that the device is low in cost, facilitate popularization and application.
Fig. 9 diagrammatically illustrates the flow chart of the method for the physical size for measuring object of embodiment of the present invention.
With reference to Fig. 9, which includes:
Step S10, at least one the reflection signal reflected from object is received；
Step S20, the signal magnitude of at least one reflection signal is determined；

The signals such as wave, preferably infrared light do not interfere with body when use of the user to product because infrared light is black light
It tests, and infrared light supply is easily obtained by inexpensive mode, such as can produce by low-cost infrared-emitting diode.This
In the physical size of object include one of length, height and width.
In step S20, when determining signal magnitude, after reflection signal can be specifically received by signal receiver, it will believe
It number is converted into analog quantity such as voltage signal, the analog-to-digital conversion port for the processor connecting with signal receiver gets voltage letter
Number, and the size of the voltage signal is converted into numerical value by the analog-digital converter built in processor, so that it is determined that the signal is big
It is small.
