短距离多点无线语音传输系统的设计与实现

结合STM32单片机,研究短距离多点无线语音通信系统的开发,探讨系统软硬件的可行性设计.通过配置硬件模块和功能软件,构建短距离多点无线语音传输系统的理论模型.结果表明:设计的系统拓宽了市面上现有对讲机的内嵌功能和使用范围,既不受信号网络覆盖局限的影响,又无需信息服务费,而且在技术层面改变传统对讲机同频单工的通信模式,实现了多点间无线语音广播、组播和单播功能.

Design and Implementation of Short-Range Multi-Point Wireless Voice Transmission System

This paper studied the development of short range multi point wireless voice communication system, combined with STM32 single chip microcomputer and discussed the feasibility of the system hardware and software design. It constructs the theoretical model of short range multi point wireless voice transmission system, by configuring the hardware modules and functional software. Result shows that the system has been designed to expand the inter embed function and using scope of the commercial interphone. It is not affected by the limitation of signal network coverage and doesn’t need information service fee. At the technical level, it has changed the traditional mode of communication with the radio frequency simplex. At the same time, it has realized the multi point wireless voice broadcast, multicast and unicast function.
