Design and implementation of virtual instruments for monitoring and controlling physical variables using different communication protocals

Abstract

In this Project were developed software components (Java Beans) which have the capability of communication through different communication protocols with hardware elements interconnected to sensors and control devices for monitoring and controlling different physical variables, conforming a hardware-software platform that obeys the virtual instruments design pattern. The implemented communication protocols are RS232, 1-Wire and TCP/IP with all of its annexed technologies like WiFi (Wireless Fidelity) and WiMax (Worldwide Interoperability for Microwave Access); also these elements communicate with a database and have the capability of sending text messages to cell phones through a GSM modem. For the development of software were used the object-oriented programming paradigm (OOP), Java programming language, LINUX OS and database server MySQL. As hardware, were used sensors and control devices in a 1-Wire network, a TINI (Tiny InterNet Interfaces) embedded system and a PIC (Peripheral Interface Controller) microcontroller. © 2007 Springer.
