Abstract： In order to effectively monitor the state of bioelectricity of standing tree， a mobile terminal system was designed to achieve the remote query of the bioelectricity producing situation of trees. The system mainly includes the hypogyny machine system for measurement and collection of bioelectricity signals， bluetooth and GSM systems for wireless remote query， and the PC system of displaying real-time data for further analysis. The system is to transmit to the next bit machine by nails electrode， the sampling circuit， amplifying circuit， A/D conversion circuit and programming interface module， will read the measured data and temporary to STC89C52RC MCU in the ROM. The user can transmit the measured real-time data to the mobile phone in the form of a short message by using the instruction-driven MCU on the mobile terminal， realizing real-time monitoring of the data. The in-situ test and application showed that the system can accurately monitor the biological energy data， and the data can be real-time transmitted to the mobile terminal for checking and recording. The system operates steadily and can meet the need of real-time monitor and query of the test data. The system is small， easy to carry and install， the use of modern smart phone terminal convenience， improve the efficiency of living wood biological power data acquisition， and has mobility， rapidity. This paper provides reference for further studies to understand the law of generation， collection， query， storage， and utilization of bioelectricity of trees.

0引言

活立木生物電是指在部分树木的韧皮部、木质部和叶片等部位和邻近土壤之间形成的一个持续的电势差或微弱的电流[1]。这种电势差大小通常在几十至几百毫伏之间，在两个电极之间连接一个电阻或负载，就会形成连续的电流[2]。在大数据背景下，利用基于物联网技术的无线传感器网络对活立木生物电产生的信息进行采集和远程终端监测，则是林业智能化的体现和要求。……
