摘要
蒸腾量是反映植物生理信息最重要的因素之一,该文提出了一种基于ZigBee技术的非侵入式无线茎流传感器,通过包裹式的加热探头给茎杆加热,由温度测量探头来确定茎流的热传输量以推算出植物的蒸腾量。并给出了茎流传感器的软硬件设计方案,将传感器探头部分与ZigBee模块集成,实现了具有ZigBee网络功能的无线茎流传感器。将所研制无线茎流传感器与以色列的PHYTALK茎流传感器进行对比性实验,其结果表明,两者的相关性为0.938,而ZigBee茎流传感器具有更高的灵敏度。
Transpiration rate is one of the most important factors that reflects the plant physiological information.This paper put forward a kind of non-ablative wireless stem flow sensor on ZigBee,which heated up the stalk by the enwrapped calefaction probe and decided the heat transfer quantity of stem flow by the value of the temperature probe to calculate the plant transpiration rate.This paper also presented the software and hardware design of stem flow sensor integrating with ZigBee module to realize wireless stem flow sensor with network ability.The comparative experiments between the wireless stem flow sensor and the Israel PHYTALK stem flow sensor showed that the correlation coefficient was 0.938,and the former had higher sensitivity.
