The paper introduces the electric energy data acquisition terminal based on the latest standard of Q/GDW373, which implements an intelligent energy acquisition system by exchanging information with the hub, collecting information from voltage current transformer and communicating with the electrical energy meter. The paper also recapitulates the function of the system, the components of hardware and the design of software. The acquisition system adopts AT91SAM9G20 of ARM9 chip and Linux multithreading technology to gather and process the data, and thus accomplishes the automatic acquisition of the embedded real-time electricity data.
