Abstract

Irrigation is a practice that increases productivity and enables the expansion of agricultural borders. This practice should be well managed to ensure the efficient use of water by plants, and such management requires specialized labor, which increases operating costs. Therefore, the main objective of this study is the implementation of an automated irrigation system that considers factors ranging from  water demand to the operation of the system. Because the daily water demand is determined by crop evapotranspiration,  a low-cost weather station was developed to acquire data daily. Such data can be used to estimate the reference evapotranspiration (ET0) using the Penman-Monteith model of the Food and Agriculture Organization (FAO). Thus, by combining the amount of water required by a crop with the physical  and hydraulic properties of the soil and the hydraulic properties of the irrigation system, it was possible to determine the daily frequency and amount of time required for the system to operate to meet the water requirements of the    crop without undergoing stress from a deficit or an excess of water. The management/monitoring system was designed and implemented to allow the  user to access data remotely through an online application. This application enables the real-time transmission of irrigation-related data, such as weather station data and system logs, obviating the need for the user to be present at the crop site. This allows the supervision of many areas simultaneously with low cost

开发低成本气象站和实时监测自动化灌溉管理
灌溉是一种提高生产力和扩大农业边界的做法。这种做法应该得到很好的管理,以确保工厂有效利用水,这种管理需要专门的劳动力,这增加了运营成本。因此,本研究的主要目标是实现一个考虑从水需求到系统运行等因素的自动化灌溉系统。由于每天的需水量是由作物的蒸散量决定的,因此开发了一个低成本的气象站来获取每天的数据。这些数据可用于使用粮农组织(FAO)的Penman-Monteith模型估计参考蒸散量(ET0)。因此,通过将作物所需的水量与土壤的物理和水力特性以及灌溉系统的水力特性相结合,可以确定系统运行以满足作物对水的需求所需的每日频率和时间,而不会因缺水或缺水而受到压力。管理/监控系统的设计和实现允许用户通过在线应用程序远程访问数据。该应用程序可以实时传输与灌溉相关的数据,例如气象站数据和系统日志,从而无需用户出现在作物现场。这样就可以以较低的成本同时监管多个领域
