低功耗树木直径生长记录仪

Low Power Consumption Tree Diameter Growth Recorders

树木直径生长量是森林资源监测的关键因子。为了定期连续有效地获得树木直径生长量,设计了一种用普通电池供电并能长期在野外自动测量的树木直径生长记录仪。该仪器由单片机、CH376模块、传感器和电源四部分组成,具有结构轻巧、操作简单,使用方便等特点,能够灵活地以1s或1s的倍数进行自动重复测量。树木直径生长量测量实验表明,该仪器测量稳定,精确度高,具有较高的实用价值。

The tree diameter increment is an important factor for forest resource monitoring. To effectively acquire the increment periodically in succession, a tree diameter growth recorder is designed, which is powered with normal batteries and can automatically measure tree growth in the field for a long time. The tree diameter growth recorder is composed of MCU, CH376 module, sensors and power source, featuring a light structure, simple operation and convenient operation, able to flexibly automatically repeat measurement in a second or times of a second. The increment measurement experiments show that this instrument has stable performance, high accuracy and practical value.
