摘要
为了解决目前国内树木的测量工具都依靠人工手动测量,且无法对树木的直径进行长期连续观测和自动记录的问题,设计了一种以MSP430F149芯片为核心的低功耗测树仪。对整个系统的软硬件实现进行了详细阐述,同时对系统功耗进行了估算及测试。该测树仪采用2节1.5 V电池供电,能够连续记录直径生长量,并提供了方便地数据采集接口,只要插入SD卡便可自动读取数据。研究结果表明,该测树仪具有结构简单、操作方便、数据自动记录与自动存储、低功耗、低成本等优点,具有较强的实用性。
In order to solve the problems that the diameter measuration in China is still based on measuring tape and can not be automatically done and the data can＇t be automatically recorded, a kind of low-power dendrometer based on MSP430Fld9 chips was designed. The hardware and software of the system were expounded in detail,and the system power dissipation was estimated and tested. The dendrometer powered by two 1.5 V batteries can record the diameter growth of the trees continuously. It also provides a convenient interface for data transferring from the system to a SD card as long as the SD card is inserted. The results indicate that the dendrometer has stronger practicability with advantages of simple structure, convenient operation, data automatic recording and automatic storage,low power consumption, low cost etc..
