精准农业（PA）是指正确评估农业需求所需的一系列实践和工具。PA解决方案的准确性和有效性在很大程度上取决于对土壤条件的准确和及时分析。在本文中，一个自动精确灌溉系统的概念验证提供了通过集成的中心枢轴（CP）灌溉系统与无线地下传感器网络（WUSNs）。这种无线地下传感器辅助中心枢轴（WUSA-CP）系统将通过使用无线地下传感器真实的实时监测土壤状况，提供自主灌溉管理能力。为此，进行了水力驱动和连续移动中心枢轴灌溉系统的田间试验。结果被用来评估经验通道模型的土壤-空气通信。实验结果表明，WUSA-CP的概念是可行的。通过地下天线的设计，与传统天线设计相比，通信范围可以提高高达400%。研究结果还表明，土壤和空气之间的无线通信信道受到许多时空方面的影响，如传感器的位置和埋深，土壤质地和物理性质，土壤水分和植被冠层高度。据我们所知，这是第一次使用WUSNs开发自主精确灌溉系统。(C)2012爱思唯尔有限公司版权所有。
Precision agriculture (PA) refers to a series of practices and tools necessary to correctly evaluate farming needs. The accuracy and effectiveness of PA solutions are highly dependent on accurate and timely analysis of the soil conditions. In this paper, a proof-of-concept towards an autonomous precision irrigation system is provided through the integration of a center pivot (CP) irrigation system with wireless underground sensor networks (WUSNs). This Wireless Underground Sensor-Aided Center Pivot (WUSA-CP) system will provide autonomous irrigation management capabilities by monitoring the soil conditions in real time using wireless underground sensors. To this end, field experiments with a hydraulic drive and continuous-move center pivot irrigation system are conducted. The results are used to evaluate empirical channel models for soil-air communications. The experiment results show that the concept of WUSA-CP is feasible. Through the design of an underground antenna, communication ranges can be improved by up to 400% compared to conventional antenna designs. The results also highlight that the wireless communication channel between soil and air is significantly affected by many spatio-temporal aspects, such as the location and burial depth of the sensors, soil texture and physical properties, soil moisture, and the vegetation canopy height. To the best of our knowledge, this is the first work on the development of an autonomous precision irrigation system with WUSNs. (C) 2012 Elsevier B.V. All rights reserved.
