| Abstract: | The development of electronic, wireless and network technology provides the strong technical support for security and convenience of modern residential quarters. In this paper, we introduce a new style wireless visual inter-conversation doorbell system, which is used in the intelligent residential quarters. Then explains the structure of this system, and it's full-duplex digital voice communication is designed and implemented. We emphasize the digital voice process in transmission, and discuss the design of the structure of frame, and the frame synchronization is realized in CPLD. Finally, the test result shows a stable and reliable quality, clear voice and fairly practical value. |
