Design Rotational Speed Measurement Device With Photoelectric Sensor
Abstract
A speed measuring device using photoelectric sensors. is introduced in this paper. The design idea of the rotational speed measurement device is determined, the hardware circuit and software program of the whole rotational speed measurement system are designed, the system debugging has aslo carried out. The core control part adopts STC89C52 microcontroller to ensure the automation and intelligence of the speed measuring device. The microcomputer and the photoelectric sensor are powered by the LM2596 stabilized regulator voltage system; The SD-1/2 photoelectric sensor is used for signal collection and processings Keil simulation software writes programs and generates corresponding codes; STC burning software burns program to the microcontroller; Configures the liquid crystal display module, designs the microcontroller display driver program, displays the final result through the 1602 liquid crystal screen, and finally enables the speed measuring device to accurately measure the object speed. Finally, the device can accurately measure the rotational speed of the object. The time accuracy of this design is 0.01s and the biggest advantage of this design is non-contact measurement, which is more practical, accurate and stable than the traditional rotational speed measurement device.
