Development of a Low-Cost Data acquisition system for Biodigester

Journal of Sustainable Bioenergy systems 2017年第3期7卷 117-137页

作者： Pedro Felipe Sousa Teixeira Luciano Fernandes Moura Stenio Wellington Sousa Lima Daniel Albiero Franklin Aragao Gondim Auzuir Ripardo de Alexandria Instituto Federal de Educacao Ciencia e Tecnologia do Ceara-IFCECearaBrazil Universidade Federal do Ceara-UFC CearaBrazil

The objective of this work is to develop a low-cost data acquisition system, which aims to optimize the anaerobic biodigestion process in an Indian model biodigester prototype, by monitoring the main parameters of the process. In this development, we decided to create a system from scratch, including the entire measure-process-show procedure using hardware tools and free software as means of reducing costs. This platform must be capable of obtaining analog data from the sensors arranged in the biodigester in long periods for the creation of more accurate reports. The system must be able to send this information to a Web server, so these values can be continuously tracked anywhere with access to the internet. The monitoring must be done in a hybrid application for An-droid, iOS and web browser.

第十五届中国科协年会第10分会场：信息化与农业现代化研讨会

作者： LUO Ning LI Handong Andrew TANG Haixu Institute of Electrical Engineering Guizhou University

In recent years, Unmanned Aerial Vehicle (UAV) has won great attention and shown its importance both in civil and military all over the world. Ground monitor and control system (GMCS) is an important part of the entire unmanned helicopter system [2] .The root purpose of most UAV systems is to extend or to replace human awareness, acquire useful information of external world [1] . As UAV develops rapidly, the functions and tasks are becoming increasingly complex, and the ground control station needs to collect more data. In addition, Establish a real-time and reliable communication system, has become an important part of the control system of the UAV. The uc/os-Ⅱoperating system with the characteristics of modular application that can be used to multi-tasking operation .It can satisfy the requirement of real time system very well. And the system successfully applied to practical UAV flighter and the setting up of The Ground Monitoring Station.
