摘要(Abstract):

设计了一种基于拉伸传感器自动测量记录树木直径的设备——一种便携式电子测径仪,该设备以单片机、传感器、卷尺和卷盘等主要硬件为基础,基于脉冲计数,通过A/D转换把传感器测得的数据转换成周长与直径,嵌入操作软件,实现林木直径的数字化精确测量。本研究将摒弃现有基于光学原理和机械原理的产品设计思路,开启测树仪器产品向集成化、微型化、数字化发展的新途径。
A portable electronic tree-diameter dendrometeris was developed based on a strain sensor to automatically measure and recordthe diameter of a tree. The main hardwares constituting the device were micro-electro-mechanical systems,sensor,tape and reel. Through A/D,the pulse count of the sensor was converted to the perimeter and diameter of the tree,which would be embedded in the operating software,to realize the digitization and accuracy of tree-diameter measurement. Beyond the existing product design ideas based on optical principles and mechanical principles,this study developed a new approach of integration,miniaturization,digital development of dendrometer.
