Abstract

The utility model relates to a device for measuring an angle speed based on a singlechip and double optical wedges. The device mainly consists of an optical wedge, a laser beam, a detected rotating body, a rotary optical wedge, an optical axis, a convex lens, a photoresistor, a resistor and a singlechip 8051. The laser beam passes through the optical axis during incoming; the optical axis and the centers of the optical wedge, the rotary optical wedge and 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 with a port of the singlechip 8051.

Description

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

Technical field

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

Background technology

Continuous progress along with science and technology, people are to the understanding of knowledge, more and more pay attention to the method for succinct high efficient and reliable, constantly pursue Novel measuring method, make it more effective, the instrument of a lot of measured angular speed is arranged in the society, but most of prices are high, 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.

The utility model content

For above-mentioned deficiency, it is a kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges that the utility model provides.

The utility model is realized by following technology: a kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges, mainly formed 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, tested rotary body and rotating wedge closely cooperate, photoresistance on the image focus of convex lens, upper termination 8051 one-chip machine ports of resistance.

The beneficial effects of the utility model are: 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 utility model.

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

As shown in Figure 1 and Figure 2, a kind of based on the device of single-chip microcomputer with the measured angular speed of two wedges, mainly formed by 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, pass through optical axis 5 during laser beam 2 incident, tested rotary body 3 closely cooperates with rotating wedge 4, optical axis 5 is by wedge 1, the center of rotating wedge 4 and convex lens 6, photoresistance 7 on the image focus of convex lens 6, upper termination 8051 single-chip microcomputers 9 ports of resistance 8.

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

Claims
