[0015] See figure 1 , 1. Microcontroller; 2. Base platform; 3. Slide rail; 4. Support; 5. Stepper motor; 6. Rotating shaft arm; 7. Transparent disk; 8. Simulating precipitation particles; 9. Fixed shaft arm; 10. Bracket; 11. Slide rail; 12. Base platform.
[0016] The speed-adjustable rotary precipitation particle standard device includes a microcontroller 1, which is connected to a stepping motor 5 to control its speed. The simulated precipitation particles 8 are fixed to any position of the transparent disk 7. The position and speed of the precipitation particles determine the precipitation particles Tangent speed.
[0017] The microcontroller 1 accurately controls the rotation speed and acceleration of the stepping motor 5 by outputting a pulse signal of a certain frequency, and the pulse driving signal sent out.
[0018] The slide rails 3 and 11 are hydraulic slide rails with a length of 50 cm. The support 4 can slide freely on the slide rails and adjust the displacement accordi...
