“Vision of Water and Fertilizer”
—— Intelligent Irrigation Robot
Introduction
With the rapid development of modern agriculture, the degree of agricultural production intensification is increasing. However, in today’s era, global climate change is abnormal, and crop pests and diseases are frequent. Traditional pest and disease identification methods mainly rely on manual labor, resulting in low accuracy. At the same time, Chinese agriculture mostly adopts manual or automatic irrigation methods for irrigating crops, leading to low water resource utilization. To address these issues, the team has developed an intelligent irrigation robot. This robot can monitor environmental information in real-time, identify pests and diseases, and intelligently proportion water and fertilizer. Compared to traditional methods, the “Vision of Water and Fertilizer” intelligent irrigation robot is more convenient and also improves the utilization of water resources in agriculture.
Design of the Intelligent Irrigation Robot
Project Overview
This project integrates technologies such as OpenMv, sensors, cloud platforms, WeChat mini-programs, and map construction to design an intelligent irrigation robot that features intelligent irrigation path planning, precise control of water outlets, pest and disease identification, and crop data monitoring. The design liberates labor, enhances agricultural productivity, and makes agricultural irrigation more intelligent.
Some Functional Modules
In the project, an upper computer function has been added, and it also has a voice module. Irrigation can be controlled via a mobile APP, and the lighting can be controlled through voice interaction. Meanwhile, the “Vision of Water and Fertilizer” intelligent irrigation robot collects image samples for identification, extracting features related to pests and diseases and feeding back to the upper computer.
Mobile APP Interface
This project is based on Arduino as the main control module, with external irrigation modules, visual recognition modules, environmental monitoring modules, and wireless transmission modules, achieving precise irrigation, integrated water and fertilizer irrigation, automatic proportioning of water and fertilizer, and pest and disease diagnosis. The project design is divided into hardware design and software design. The core hardware modules include: precise irrigation control, automatic water and fertilizer proportioning, visual recognition module, and remote control terminal. The software design is divided into integrated irrigation, medication inquiry, and pest and disease monitoring.
Software Interface
Function Implementation
The intelligent irrigation robot in this project has pest and disease early warning and alert functions. By analyzing the collected data, it determines the occurrence trend and trajectory of pests based on the growth process from pupae to adult insects. It then matches specific pest and disease types using a pest and disease knowledge base. The WeChat mini-program provides corresponding prevention and control suggestions based on the disease database and issues timely alerts when abnormal situations are detected, providing timely decision-making support for farmers and managers. Additionally, the visual recognition module OpenMV identifies the growth status of crops, extracting features related to pests and diseases from the collected images, comparing and analyzing them with the data in the WeChat mini-program database to timely detect and predict pest and disease situations, providing timely and accurate information support for agricultural prevention and control.
WeChat Mini-Program Interface
The intelligent irrigation robot in this project features integrated water and fertilizer-saving irrigation functions. By combining sensors, wireless communication, and other technologies, it monitors external environmental and soil conditions, implementing an integrated water and fertilizer control system. It achieves online monitoring based on farmland and configures the required amount of water and fertilizer through the WeChat mini-program according to the soil status of the crops. The system automatically performs irrigation, rationally regulating irrigation water and soil moisture to meet the moisture needs of the crops.
Automatic Water and Fertilizer Proportioning
Integrated Water and Fertilizer
The intelligent irrigation robot in this project has a map construction function. The robot uses the ROS system and laser radar to remotely log in from the terminal to complete map construction, enabling the robot to intelligently plan routes.
The intelligent irrigation robot in this project also features voice interaction capabilities, allowing users to control the irrigation system through voice commands. At the same time, the system can verbally report the current status of the farmland, irrigation, and fertilization plans.
Voice Interaction
Project Summary
The “Vision of Water and Fertilizer” intelligent irrigation robot project employs IoT, sensors, computer vision, and other technologies, integrating hardware and software design to achieve integrated water and fertilizer-saving irrigation, automatic proportioning, pest and disease early warning identification, map construction, and crop growth trend assessment. This robot can perceive soil and crop conditions in real-time, make automatic decisions, and execute irrigation and fertilization tasks. Users can also remotely control and view data through the WeChat mini-program. The project has achieved phased results, and future work will optimize functions and strengthen data security and cloud computing. It offers advantages such as improving agricultural productivity, saving resources, and promoting sustainable development, while being user-friendly and highly applicable, significantly contributing to the modernization of agriculture.
