Abstract

The invention relates to a device for measuring an angle speed based on a single chip and double optical wedges. The device mainly consists of optical wedges, a laser beam, a detected rotating body, a rotary optical wedge, an optical axis, a convex lens, a photoresistor, a resistor and a single chip 8051. The laser beam passes through the optical axis during incoming; the optical axis and the optical wedges, and the rotary optical wedge and the centre of the convex lens are on the same line; the detected rotating body is tightly matched with the rotary optical wedge; the photoresistor is on an image focus of the convex lens, and the upper end of the resistor is connected to a port of the single chip 8051.

Description

A kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges

Technical field

The present invention relates to mechanical engineering and optical engineering field, specifically a kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges.

Background technology

Along with the continuous progress of science and technology, people more and more pay attention to succinct high-efficiency reliable method to the understanding of knowledge; Constantly pursue new measuring method, make it more effective, the instrument of a lot of measured angular speed is arranged in the society; But most of expensive; Not easy to operate, damage easily, therefore a kind of device of the measured angular speed based on simple cheap becomes a kind of very urgent requirement.

Summary of the invention

To above-mentioned deficiency, the invention provides a kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges.

The present invention realizes through following technology: a kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges; Mainly form by wedge, laser beam, tested rotary body, rotating wedge, optical axis, convex lens, photoresistance, resistance, 8051 single-chip microcomputers; Pass through optical axis during laser beam incident; Optical axis and wedge, the center of rotating wedge and convex lens is on a line, and tested rotary body and rotating wedge closely cooperate; Photoresistance on the image focus of convex lens, last termination 8051 one-chip machine ports of resistance.

The invention has the beneficial effects as follows: this agency cost is cheap, simple in structure, and easy operating can accurately be measured the anglec of rotation and angular velocity.

Fig. 2 structural principle synoptic diagram 2 of the present invention.

Among the figure, 1. wedge, 2. laser beam, 3. tested rotary body, 4. rotating wedge, 5. optical axis, 6. convex lens, 7. photoresistance, 8. resistance, 9.8051 single-chip microcomputers.

Embodiment

Like Fig. 1, shown in Figure 2; A kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges; Mainly be made up of wedge 1, laser beam 2, tested rotary body 3, rotating wedge 4, optical axis 5, convex lens 6, photoresistance 7, resistance 8,8051 single-chip microcomputers 9, through optical axis 5, tested rotary body 3 closely cooperates with rotating wedge 4 during laser beam 2 incidents; Optical axis 5 is through wedge 1; The center of rotating wedge 4 and convex lens 6, photoresistance 7 on the image focus of convex lens 6, last termination 8051 single-chip microcomputers 9 ports of resistance 8.

Its principle of work: when tested rotary body 3 was in accompanying drawing 2 positions with rotating wedge 4, laser beam 2 was not because the cause of refraction is passed through on the image focus of convex lens 6, and this moment, the voltage of resistance 8 was very little; After 180 degree rotations, when tested rotary body 3 was in the position of accompanying drawing 1 with rotating wedge 4, laser beam 2 can be through the image focus of convex lens 6; The resistance of photoresistance 7 can be less rapidly; The voltage of resistance 8 raises, and 8051 single-chip microcomputers 9 ceaselessly scanning port are noted the moment that the voltage of resistance 8 raises, again through after the 180 degree rotations; 8051 single-chip microcomputers 9 write down the moment that resistance 8 voltages raise once more; Do not stop cycle index like this, 8051 single-chip microcomputers 9 write down through 180 degree and time several times accordingly, thereby calculate angular velocity.
