将数据保持在智能灌溉网络的边缘：草莓温室的案例研究
Keeping data at the edge of smart irrigation networks: A case study in strawberry greenhouses
摘要：
草莓因其香气、鲜红色、多汁的质地和甜味而广受欢迎。然而，它们是对最终产品质量最敏感的水果之一。最近的商业趋势表明，越来越多的农民直接销售他们的产品，并有兴趣使用智能解决方案对产品进行持续的质量控制。近年来，基于云的智能灌溉方法得到了广泛应用。然而，与网络边缘之外的第三方共享作物数据带来的网络流量、安全和监管挑战，导致草莓种植者和数据所有者依赖全球云，并可能失去对数据的控制，这些数据通常被转移到第三方数据中心。在本文中，我们遵循三步方法来设计，实施和验证温室智能草莓灌溉解决方案，同时将相应的数据保存在网络边缘：（i）我们开发了一个小规模的智能灌溉原型解决方案，包括现成的硬件和软件设备，我们在不同种类的植物上进行测试和评估，以获得更大规模部署的有用见解，（ii）我们引入了一个参考网络架构，专门针对草莓温室的智能灌溉和边缘数据分发，和（iii）采用建议的参考架构，我们在希腊的实际草莓温室环境中实施了一个全面的系统，并将其性能与传统的草莓灌溉进行比较。我们表明，我们的设计显着优于传统的方法，无论是在土壤水分变化和耗水量方面，并得出结论，严格评估我们的方法在农业行业的成本和效益。
英文摘要：
Strawberries are widely appreciated for their aroma, bright red color, juicy texture, and sweetness. They are, however, among the most sensitive fruits when it comes to the quality of the end product. The recent commercial trends show a rising number of farmers who directly sell their products and are interested in using smart solutions for a continuous quality control of the product. Cloud-based approaches for smart irrigation have been widely used in the recent years. However, the network traffic, security and regulatory challenges, which come hand in hand with sharing the crop data with third parties outside the edge of the network, lead strawberry farmers and data owners to rely on global clouds and potentially lose control over their data, which are usually transferred to third party data centers. In this paper, we follow a three-step methodological approach in order to design, implement and validate a solution for smart strawberry irrigation in greenhouses, while keeping the corresponding data at the edge of the network: (i) We develop a small-scale smart irrigation prototype solution with off-the-shelf hardware and software equipment, which we test and evaluate on different kinds of plants in order to gain useful insights for larger scale deployments, (ii) we introduce a reference network architecture, specifically targeting smart irrigation and edge data distribution for strawberry greenhouses, and (iii) adopting the proposed reference architecture, we implement a full-scale system in an actual strawberry greenhouse environment in Greece, and we compare its performance against that of conventional strawberries irrigation. We show that our design significantly outperforms the conventional approach, both in terms of soil moisture variation and in terms of water consumption, and conclude by critically appraising the costs and benefits of our approach in the agricultural industry.
