The development of the intelligent building community has also been gradually arisen.What’s the called intelligent building area,it means to control system, security system, community property management system and comprehensive service as the backing, Use of high-tech means to set up the Internet information service platform.According to the current situation, the ubiquitous power line is used to establish the power carrier communication is often the most economical and most practical a method. Integrated PLL decoder LM567 has a good noise reduction capabilities and centre frequency stability and are widely used in a variety of communications equipment in the decoding and AM, FM signal demodulation circuit. Adoption of this article is within the family using power line as transmission carrier, With LM567 as the core, Sent via modulation and demodulation signal, Realized the voice on the line multiplexing transmission of signals and control signals. The corresponding community management in after collect family informatio
