【摘要】 本文通过在广州从玉菜场的水分传感器网络监测田间水分的项目运作出发,介绍了水分传感器网络在田间监测的硬件节点设计、拓扑结构、通信方案、增加覆盖度的远程传输等具体实施方案。试验表明,所设计的无线水分传感器实现了低成本、低功耗,发射距离可以达到70米以上,配备3节电池后,按照间隔4小时采集1次水分数据的试验,网络节点生命期可以支持100天左右。此外,分析实施过程中面临的一些困难以及相应的解决办法,进一步地探讨了无线传感器网络在我国精细农业中更大范围内应用的实施方案建议。更多还原

【Abstract】 This article described the water sensor networks to monitor the field moisture from the project working, introduced in the field of water monitoring sensor network topology, communications mechanisms, and the coverage scheme of long-distance transmission. Tests show that the design of wireless water sensors to achieve a low-cost, low power consumption, can be fired from more than 70 meters, is equipped with three batteries, the 4-hour intervals in accordance with the acquisition of a second moisture test data, the network node can support life about 100 days. In addition, the analysis of the implementation of some of the difficulties faced and corresponding solutions, and further explore the wireless sensor networks in precision agriculture in China’s wider application of the proposed implementation plan.更多还原
