Atpresent, the power line munication technology isrelatively mature, the basic coverage ofthe New District, the construction cost islow, isthe best way toachieve munity. Inthis paper the use ofpower line channel technology influence the outstanding characteristics ofnoise and attenuation characteristics are analyzed, argument toselect the suitable modulation; FSK modulation for power munication system performance analysis, modem design toenhance the anti-interference ability, transmission distance and transmission rate; according toVisual Basic todesign the munity management center system, inorder toonthe part ofresidential were remote control and management, and achieve the area ofinformation collecting, sorting and storage. On this basis, the munity munication testing and analysis, verify the reliability ofthe modem and software, demonstrated the feasibility ofpower line munication inthe realization of intelligent residential quarters.
