Development of 3G Smart Meter System Based on Internet of Things

As a tool for energy metering, electric meter is the function integration base of smart grid. Traditional mechanical meters and ordinary electronic meters havent met the needs of the modern smart grid. In this paper, a novel smart meter system based on 3G is proposed. This 3G smart meter system is integrated of some new technologies, such as effective energy metering, embedded MCU, 3G wireless communication & Database management. The constitution of system and the hardware and software design have been introduced in detail in this paper. The experiment shows that some real-time energy measurement parameters have been provided to power users by the 3G smart meter system, and the two-way wireless data communication between power users and power corporations has been accomplished effectively. Furthermore the management level of power corporations has been promoted.
