Measuring and controlling system based on computer for seed processing equipment

The key method designed in the hardware and software of the measuring and controlling system based on computer for the seed processing equipment was described. In the system, the instant test of various parameters including vibration frequency, wind rate, wind capacity, revolution speed, temperature and rotation angle were realized. And the video monitoring of the operating condition of some key parts of the equipment was described. The controlling parameters such as motor speed, working flow, screen surface vibration frequency, wind rate and wind capacity were combined to the automatic control function in processing. Based on the virtual instrument technology, a humanized human-computer interface integrating the advanced graphical user interface, animation designing and video monitoring organically were designed. Applications in practice indicate that it owns high real-time performance and dependability, and that it improves the quality of the forage grass seed in its mechanized processing procedure.
