面向新疆大田智慧滴灌系统的设计

Design of a Smart Drip Irrigation System for Xinjiang Agriculture

节水滴灌是新疆农业现代化的标志性成果,全疆微灌面积位居全国第1,发展滴灌自动化迫在眉睫。但是,现有滴灌自动化产品存在成本高、野外供电困难、信号传输困难、农艺专家知识无法沉淀和优化等问题。为此,设计出一套适用于新疆大田的智慧节水滴灌系统。该系统由3部分组成:一是适用于新疆大田环境的滴灌控制器;二是适用于农业数据交换的通信协议和硬件实现;三是农业大数据云平台。滴灌控制器整合供电、通信和控制模块,降低了成本,增强了鲁棒性。基于LoRa的通信协议降低了功耗,增强了在高杆植物环境下的抗干扰性。大数据云平台可实现对环境的自动感知,对滴灌系统的智能控制,对专家滴灌方案的保持和持续进化。三者结合,可以从整体上提高滴灌系统的自动化、信息化和智能化程度。

Drip irrigation is a milestone in the modernization of agriculture in Xinjiang. Xinjiang micro-irrigation area ranked first in the country. However, the existing drip automation products have several problems: the cost is high, on-site power supply is difficult, signal transmission is difficult, expert knowledge can not precipitate and optimize. This paper presents a novel system for smart drip irrigation system to solve the above problems. The system consists of three parts: the drip irrigation controller, the data communication protocol and hardware implementation, the agricultural data cloud platform. The drip controller integrates power, communication and control modules, reducing costs and enhancing robustness. The LoRa-based communication protocols reduce power consumption and enhance the anti-jamming capability. The cloud platform achieves the intellectual decision base on the perception of environment. Combined with the three, the system improves the drip irrigation system as a whole in the aspect of automation, information and intelligent.
