基于无线传感技术的稻田信息监测系统

针对稻田信息监测周期长、环境干扰大、采集速度慢、采集方式管理缺乏自动管理等特点,设计了一种基于无线传感技术的稻田信息监测系统。同时,采用Cluster Tree+AODVjr路由算法和分簇算法进行组合,设计了具有异构性能的节点,配置了不同的天线类型,提高数据传输距离和质量。实验数据表明:该系统可以采集稻田的温度、湿度和土壤含水量,运行稳定,数据正确传输率都在90%以上,空气温度、空气湿度和土壤含水量的相对误差分别为0.43%、0.34%和0.73%。

Paddy Information Monitoring System Based on Wireless Sensor Technology

In view of the characteristics of long monitoring period, great environmental interference, slow acquisition speed and lack of automated management in the process of farmland environmental data collection,paddy information mo-nitoring system based on wireless sensor technology was designed, designed, used cluster tree +AODVjr routing algo-rithms and clustering algorithms, design nodes with heterogeneous properties, and different antenna types were configured to improve data transmission distance and quality.It analyzes in details the composition structure, hardware design, soft-ware design, and networking process of the proposed system.Experimental data show that the system can collect paddy temperature,humidity and soil moisture, and the system runs stably and the measurements are accurate.Correct data transfer rate of system were higher than 90%, and the relative errors air temperature,air humidity and soil moisture were 0.43%,0.34% and 0.73%.
