一种便携式电子测径仪的研制

Development of a Portable Electronic Tree-diameter Dendrometer

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.
