Development of the Multi-Function Meter with Wireless Communication and the Internet

Wu, Hung-Chang 19 July 2005 (has links)
Traditionally, power companies manage utility bills by sending agents to customer houses to take the consumption records by hand and send the records to data bank at the control center. It is difficult and in-efficient to keep track of these records. In addition, the possible man-made mistakes on information management may add extra personnel expenses. This thesis incorporates such techniques as AT90S8515 Imbedded Chip, electronic circuits, and GSM (Global System for Mobile Communications) infrastructure into a comprehensive ¡¥Automatic Power Consumption Report System¡¦. The system provides an immediate transmission of the consumption records, which changes the traditional manual method to collect records. Meanwhile, the GSM and the SMS (Short Message Service) are also incorporated to provide the capability of informing the management of emergent messages such as unusual situations of the consumption records acquired. Through TCP/IP, the system integrates VB (Visual Basic) Communication Protocol, ASP (Active Server Pages), and SQL (Structure Query Language) to achieve the function of remote monitoring through the Internet and to enable the consumers the possibilities of checking their own consumption records with Internet Explorer remotely.
