Abstracts Information technology in national economic development has become increasingly important, various of newly arisen correspondence technique change with each passing day. At the same time, as the country's economic fitness strategy towards conservation-oriented changes, all based on the traditional medium and technological upgrading of equipment which has been laying and new technical research and development are also progress to rise. Although not a new power line communication technology field, but can use the rich power resources in the data communications and industrial applications, which has broad social value and economic value. Following to the ultra-large-scale digital circuit technology development, the application of SCM in our lives are also very popular. This paper is presented in a AT89C51 microcontroller as the core to the simple power line loading dual signal recognition system design. In this system, we design the integrated power, frequency signal generator, and use of four light emitting diode as Display interface, double-button switch-mode power line load control signal. The hardware circuits of this system is simple, and software runs reliable, low cost, with expansibility.
