VoIP在智能小区对讲系统中的设计与实现

本文介绍了一种基于IP的智能小区对讲系统,是国内首次将VoIP技术应用在智能小区领域。该系统由门口机、用户机和管理机构成,之间用以太网相连接。语音信号进行数字化、压缩处理后转换为IP数据包在IP网络上进行传输,是一个全双工的实时语音传输与处理系。文章分别介绍了该系统的硬件结构和软件实现方法。

Development of VoIP-based Intercom System in Smart Community

In this paper, an IP-based Intercom system applied in smart community is presented. It's for the first time that VoIP technology is applied in this field. This system consists of user node, doorway node and administrator node which are connected through Ethernet. The voice packet is transferred over IP network after the audio signal is digitized, compressed and packed. It's a full-duplex real-time voice transport and processing system. The paper describes its hardware architecture and software implementation.
