Multifunction Intelligent Dynamic Weighing System Based on Embeded Computer

摘要

A weighing instrument system embedded multifunctional intelligent has been developped, and a compensation method proposed to improve the measurement accuracy of the system performance. Weighing instrument took embedded computer as the core, used the logic processing of the powerful FPGA, USB interface data communication function connecting to the PC machine to build host/slave system. Dynamically compensate in the series compensation link to solve the system of nonlinear strength, poor dynamic performance of sensor, short the time to reach the steady state for the whole measurement system. Results show that the system is suitable for the requirement of fast measurement, effectively improve the accuracy and reliability.
