WEB-BASED REAL TIME DATA ACQUISITION AND INTERACTIVE CONTROL OF APPLIANCES USING ETHERNET CONNECTIVITY A. DINESH & ANJU S. PILLAI Department of Electronics and Electrical Engineering, Amrita Vishwa Vidyapeetham University, Coimbatore, Tamil Nadu, India ABSTRACT Revolution in the technology helps to increase the living standards of human life and building automation technology has a significant contribution to this advancements. The concept of internet of things binds the object around, to the web world to facilitate the remote access and control. This paper presents sharing of real time data over the internet and enable interaction and control of the device from remote location. A stand alone web server is developed using LM3S8962 stellaris family microcontroller with inbuilt ethernet controller and Light weight Internet Protocol (LwIP) stack is ported, to facilitate the supervision of home appliance. A Graphical User Interface (GUI) developed using web technologies provide an effective user interaction. The functionality of the prototype system is checked and verified. KEYWORDS: Internet of Things, GUI, Home Controller Unit, Interrupt Mechanism, Interactive Control, LwIP Stack INTRODUCTION Due to the fast growth in technology, automatic systems are playing important role in our day to day life. Introduction of intelligent system and smart devices helps to save time, reduce the human effort, provides automatic control, eliminates the human error and reduce the energy wastage. Evolution of smart device led to internet of things. Internet of things involves machine to machine, machine to environmental and machine to human interaction. Building automation system or intelligent building system in residential and commercial complexes is popular due to safety, security and efficient energy management. Due to human crave for sophistication and automation; smart building with energy management and security system have become very popular and demanding. Total building solutions include: building automation, video surveillance, fire protection, efficient monitoring and control of heating, alarm systems and many more [8]. In order to obtain building automation and energy management, the independent systems need to work as a single unit with cohesive nature. This will provide increased performance with intelligent control. Web-empowered or browser based systems are latest addition to building automation technology. These systems add more flexibility, easy and remote access for man-machine interface. Controlling any number of device are made possible with an infrastructure less effective GUI through web based building automations. The rest of the paper is organised as section 2 describes the related work in the field of building automation followed by system architecture in section 3. Section 4 details the hardware description and in section 5 details about the software requirements. Finally section 6 and 7 summarizes the results and conclusions of the proposed. RELATED WORK In earlier days, the controls of the devices were done only through direct means by the use of switches.
