Abstract

A computer measurement and control system of test device for grain drying is designed by combining virtual instrument technology and computer measurement and control technology. Working done by hand or half hand system is solved by the automatic system. The hardware is designed with computer and ADAM module as its core, and the software is developed by Lab Windows/CVI. Digital incremental PID control algorithm is used in the process control. Anti-interference technology for hardware and software is applied. The result of experiment indicates that the temperature error was less than ±1°C", "the moisture error was less than ±2.17%and wind speed error was less than ±0.1m/s. The computer measurement and control system has a good performance and reaches the design and application requirements well.
