摘要:
 设计了一种基于拉伸传感器的自动测量记录树木直径的设备—树木直径记录仪,记录仪由单片机、时钟模块、CH376模块、传感器和电源5部分组成。时钟输出时间,通过AD转换把传感器测得的数据转换成周长与直径,CH376用来对单片机进行数据的读写,电源模块控制向所有的其他模块供电。先设定好初始时间和测量间隔时间,然后进入休眠,仅时钟模块运行。当时钟运行到设定的测量时间,系统被唤醒,拉绳传感器得到的模拟量通过AD转换成周长与直径,并存入flash,随后再次进入休眠,如此往复。该系统采集数据简单,将U盘插入系统所带的USB接口,系统会自动识别,并将数据复制到U盘。通过试验可看出,用本仪器测得值的平均值来代替实际值,精度较高。
Abstract:
 Diameter is the most important factor in forest inventory.A drawware sensor based tree diameter recorder that could automatically conduct the measurement was designed with SCM,clock module, CH376 module, sensor, and power module.The working principles were described as follows.Clock exports time, and the data measured by sensor are transformed into perimeter and diameter by AD.CH376 is used to read and write data.Power module regulats power to other modules.To conduct the measurement,the original time and time interval are set firstly,then clock module enters into hibernation and only time module functions.When the setting time is reached, system will be awakened and the analog measured by drawware will be transformed into perimeter and diameter and was stored in flash and then it entered into hibernation again.The system would be circulated like this.The system can gather data easily.After the U disk is inserted into USB port,the system will identify automatically and to copy the data to U disk.The accuracy of the data measured by this device is higher after the actual values are substituted by average values.
