Development of a remote environmental monitoring and control framework for tropical horticulture and verification of its validity under unstable network connection in rural area

Display Omitted Remote monitoring and control framework under unstable network connection.The framework consists of local and global management subsystem.Evaluated on tropical horticulture monitoring and soil moisture content control. This study focuses on the development and evaluation of a remote field environmental monitoring and control framework, implementing a local-global management strategy to overcome the unstable network connection in the rural area. The framework consists of environmental monitoring and control node as the local management subsystem (LMS), and the web data providing and system management as the global management subsystem (GMS) to establish a simple and flexible remote environmental monitoring and control based on a cloud platform. The supporting features are online and offline environmental monitoring, synchronization of system configuration, actuation, and offline management. Two field tests were conducted to verify its performances and functionalities, (1) environmental monitoring on tropical horticulture cultivation in Yogyakarta, Indonesia, and (2) implementation of the monitoring and control for automatic drip irrigation control based on soil moisture content for tomato. As the result of the first test, the developed framework could help to maintain the sustainability of environmental monitoring under unstable network connection over 80% availability of the data with local offline measurement up to 24% of the total entries. From the second test result, the framework could support the real-time monitoring and control of soil moisture content as well as increase the system flexibility in the adjustment of the system configuration remotely. The control system has 0.78% error (E) and 99.2% in-range soil moisture content (L

Development of Actuation Framework for Agricultural Informatization Supporting System

Abstract Agriculture faces many challenges in the production system, such as climate and weather, field conditions, crop types, soils types and conditions, and so on. Farmers consider many aspects to optimize the “on-farm” process by their long-term experiences. Various informatization agricultural supporting systems have been developed using ICT (Information and Communication Technologies) to improve agricultural productivity. Authors have developed the ICT-based agricultural supporting system called the “Agri-eye” in which a field monitoring, crop growth and quality evaluation, work recording, and online data offering and sharing sub-systems were incorporated. On the other hand, an actuation sub-system for controlling and managing agricultural facilities in a greenhouse such as a heater, water pumps, circulation fans, a CO 2 generator, etc. has been introduced. In this study, an actuation framework is developed as a useful method for monitoring and controlling local facilities and machineries. The method can be used for controlling particular device with adjusting parameter from Agri-eye server to meet the cultivation requirement. Furthermore, the validity of the developed framework was verified to monitor and control air temperature in laboratory test box.

Sensing and Visualization in Agriculture with Affordable Smart Devices

Information Communication Technology (ICT) can be applied to improve agricultural production in terms of advancing the knowledge and techniques of farming, reducing production costs, and improving the quality of agricultural produce. Various ICT systems to support and improve agricultural practices have been developed, focusing on environmental measurement and control, plant growth and motion estimation, and farm work recording. This chapter describes the development of several ICT systems to support small- and medium-scale farms in Japan using affordable smart devices such as low-price microcomputers and sensors and open-source software. The authors introduce these systems alongside evaluation results for their feasibility.
