The automatic counter is provided with a photosensitive diode GD, a positive terminal of the photosensitive diode GD is connected with a power supply through a resistor R1, a negative terminal of the photosensitive diode GD is connected with a base electrode of a triode V, an emitting electrode of the triode V is grounded, a collector electrode of the triode V has one path connected with the power supply through a resistor R2 and the other path connected with a ones counter through a rectification circuit, and the ones digit counter is connected with a hundreds counter through a tens counter; and the ones counter is connected with a ones display nixie tube through a ones display coder, the tens counter is connected with a tens display nixie tube through a tens display coder, and the hundreds counter is connected with a hundreds display nixie tube through a hundreds display coder.
Description
Technical field:
The utility model relates to a kind of optical experiment instrument, especially a kind of simple in structure, with low cost, be easy to carry, easy to operate, count results optics light and shade striped auto-counter accurately.
Background technology:
At present, about the experiment of interference and diffraction, all be to count in the laboratory by eye-observation and to the light and shade striped, there are the following problems:
1. because eyes to the sensitivity difference of light, are easy to generate bigger counting error, influence the accuracy of experimental result;
2. waste time and energy the progress of influence experiment;
3. laser instrument is mostly used in this type of experiment, and long-time the observation causes eye fatigue.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical matters of existing in prior technology, provide a kind of simple in structure, with low cost, be easy to carry, easy to operate, count results optics light and shade striped auto-counter accurately.
Technical solution of the present utility model is: a kind of optics light and shade striped auto-counter, be provided with photodiode GD, the anode of photodiode GD joins by resistance R 1 and power supply, the base stage of the negative terminal of photodiode GD and triode V is joined, the grounded emitter of triode V, the collector of triode V leads up to that resistance R 2 is joined with power supply, another road joins by a rectification circuit and a digit counter, and individual digit counter joins by ten digit counters and hundred digit counters; Individual digit counter shows that by an individual display decoder and a position charactron joins, and ten digit counters join by ten display decoders and ten demonstration charactrons, and hundred digit counters join by hundred bit decoders and hundred demonstration charactrons.
The set photodiode of the utility model can automatic reception light and shade striped light intensity change, through amplification rectification, code conversion is digital signal, finally by showing that charactron shows that striped is by the bright number of times of dark change, solved the existing problem of artificial counting, have simple in structure, with low cost, be easy to carry, easy to operate, advantage such as count results is accurate.
Description of drawings:
Fig. 1 is the circuit theory diagrams of the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: a kind of optics light and shade striped auto-counter, be provided with photodiode GD, the anode of photodiode GD joins with power supply VCC (high level) by resistance R 1, the base stage of the negative terminal of photodiode GD and triode V is joined, the grounded emitter of triode V, the collector of triode V leads up to that resistance R 2 is joined with power supply VCC (high level), another road joins by a rectification circuit and a digit counter, and individual digit counter joins by ten digit counters and hundred digit counters; Individual digit counter shows that by an individual display decoder and a position charactron joins, and ten digit counters join by ten display decoders and ten demonstration charactrons, and hundred digit counters join by hundred bit decoders and hundred demonstration charactrons.
Operating process:
Photodiode GD is placed on light and shade striped place, and when striped was bright by dark change, the light intensity that photodiode GD receives changed, and photodiode GD resistance changes the voltage of triode V base stage from large to small, by triode V this change in voltage is amplified.Electric current by resistance R 2 is through rectification circuit, again through counting circuit, decoding scheme, at last by charactron show that hundred place readings are zero, ten place readings are zero, individual place reading is 1.Light intensity is once bright by dark change again, and this process is carried out once again, and units sign indicating number pipe is shown as 2, and the like, show the number of times that changes by charactron at last.
