Design Of Multi-Function Power Meter Based On PL3201

With the development of economy and the the revolution of power system in our country, domestic market will have plenty of demands on muti-function power meter in next years. Along with the development of electronic and communication technology, many powerful integrate circuit become the first choice in our design. Futhermore, a more big challenge is bring forward in the auto-read power meter system and the power fare time-sharing measurement. This paper is occurred in this background, and then, design and implement a kind of muti-function power meter based on SoC.The muti-function power meter in this article implemented power measurement, carrier communication, infrared communication, realtime cell on single chip. This design fulfilled all high-powered requirement which is put forward by user, this method will make the design easy, and improve the system reliability, this solution is a new trial.This paper is based on the power meter criterion of An Hui, and analyze the requirement of muti-function power meter fully, also introduce the principle of power measurement and carrier communication, and then, design the hardware and software in detail, and discuss the key point and difficulties. The expatiate of software is the best particular. In order to exertion the function of the single chip system, each embedded function module need to debug one by one, for sake of reliability and anti-jamming, different methods is used in this paper. at last, the original target is implemented in this paper.The emphases of this paper is the application of the PL3201, and now, the single chip system solution is uncommon. The difficulty of this article is on the realization of the carrier communication module. By using CDMA technology in this design, the inter-jamming of read meter in different area will be decreased in almost degree.The system provided upstanding consult to the development of muti-function power meter, having practical meaning.
