Embedded system for building usage tracking through the computer network

Abstract

Inside a place or building are should be always checked the usage. It is important about the security and energy reduction from user. Therefore, electronics and computer technology were applied for investigation and tracking inside the building. The building usage tracking device was developed to be easy to use and independent installation without connecting other electrical devices. The aims of the study were to design and develop embedded system for building usage tracking through the computer network. The system was designed for detection of three environmental factors: motion, temperature and light. The data processing was evaluated by decision tree algorithms. After analysis, the building usage data was presented in several types such as, room in use, room not in use and air conditioner turned on without user, etc. Analyzed data were then sent via local wireless computer network to central data processing. All data were recorded in database, processed to display in terms of graphics, messages, graphs and notified. The system was tested in the building of KMITL Prince of Chumphon Campus and the results showed that the device had accurate measurement. The percentage error of temperature and light were not over 1% and 4%, respectively. In addition, the device also detected the motion in the area of 2 x 6 square meters and the system could be displayed via web browser.
