摘要

介绍智能化木材含水率测试系统的电路设计、硬件构成和工作流程,提出采用动态补偿方法,可消除由零点漂移、温度漂移等引起的测量误差。经验证,在纤维饱和点以上时,含水率自动测试系统的平均误差小于4%;在纤维饱和点以下时,误差小于2%,尤其在终含水率（14%,9,%）范围内误差小于1%。

Abstract

An intelligent MC measuring system for lumber was designed by the authors and presented in this article.The hardware circuit and software flow chart of this system are described in detail.A dynamic compensation method is applied to eliminate zero drift and temperature drift errors.A test showed that the mean errors of the measured results from this new system was less than 4% above fiber saturation point,and less than 2% below fiber saturation point,and even lower tian 1% around the final MC（14%～9%）.These results demonstrated the precision and reliability of the system to be effectively improved.
