本文给出了根据干燥基准和由称重法测得的样板含水率以控制木材干燥窑内干、湿球温度变化的单片机控制方案,叙述了其工作原理、工作过程以及防干扰措施。

Abstract

A practical microcomputer system for controlling wood drying has been designed and is introduced in this article. A circuit diagram for the controller is also included. The system is based on weight loss of the wood according to drying schedules for certain species of lumber. Moisture content variation of sample boards is determined by weight measurements. The system is able to effectively control temperature variation of both drybulb and wetbulb. Then the author presents the working principle, working process and some measures for antidisturbance of the system.
