Employing S3C2410 as the core component, a kind of concentrator in power energy information acquisition system based on the Internet and the short-distance communication technology Zigbee has been designed in this paper. The structure and function of the system has been introduced too. The Internet and Zigbee communications are realized and parts of the circuits and flow charts are given. This system uses the short-distance communication technology Zigbee to realize the data transmission between concentrator and collector, and then uses the Internet to carry the data to the superintendent center, and realizes the remote brail and management function. Empirical results show that this system can primly realize the itinerant excerption of the ammeters, the analysis of the statistical electric dosage, and the remote control of switch on and off. This system has the low cost, high reliability and stability, it can advance the automation level of the electric power management, and has a good foreground.

The zero-cross modulation technology is a communication technology for distribution network, different from the traditional distribution network power line carrier communication technology. Its basic principle is to use the TWACS of the power frequency voltage fundamental wave to realize the signal transmission, and the modulation signal frequency is low It can be long-distance communication across the transformer. The data reliability and data through rate are high. It has broad application prospects in real-time communication less demanding situations. This paper first introduces the principle of the zero-cross modulation technology, and then details the generation and the identification of the voltage modulation signal. Practice shows that the transmission success rate of zero-cross modulation signal is up to100%. Meet the actual needs.
