应用SIP协议的楼宇对讲系统设计与实现

通过对SIP协议功能及特性的研究,将SIP协议应用到传统的小区楼宇对讲系统.提出一种新型的基于SIP协议的小区楼宇对讲系统解决方案,克服了传统方案的许多不足,解决了楼宇对讲网络与因特网、通信网的无缝融合,可实现家居门禁移动对讲,提升楼宇智能化水平.设计一个嵌入式终端SIP协议栈,完成基于该协议栈的楼宇对讲系统终端的实现,并搭建一个小型的楼宇对讲系统,验证了方案的可行性.测试结果分析表明:该方案具备了较好的可行性和稳定性.

Solution of Building Intercom System Using SIP Protocol

After carefully studying on the function and feature of SIP protocol, we applied SIP protocol to traditional building intercom system, and proposed a new building intercom system solution based on SIP protocol. The new solution will overcome some weakness of traditional solution, integrate with internet and communication network, provide mobile communication with the house entrance guard, and improve the intelligent of building. In this solution, a SIP protocol stack which can work in an embedded terminal was designed, the building intercom system terminal were implemented based on protocol stack. At the end, a small scale building intercom system was set up to test our solution. The test results confirm the feasibility and validity of the solution.
