基于ARM的多用户电度表的设计

iming at the present situation of the main electricity measurement problems existing in the field where many power user are living together, such as residential area or student’s apartment , a kind of multi-user electronic energy meter has been designed in this article. This electrical energy table uses LPC2210 to take the processor, accepts the electric quantity gathering module the pulse information and saves the user and the electric quantity information, in falls the user and the electricity consumption information real-time memory in the memory which the electricity does not lose, controls the LED module demonstration user information, controls the keyboard module to carry on the correlation operation, and may carries on the real-time electric quantity information through the RS485 data bus and electric quantity gathering and the control on position machine the transmission and the control.The present paper main design electric quantity information carries on the real-time transmission through the RS485 bus line the design, including the data transmission before initialization, the data transmission frame definition and the function, and other drains harasses the aspect the research
