| 摘 要： | 针对目前无线传感器网络( WSNs)对语音传输的不足,设计和实现了一种基于WSNs的无线语音通信机制.采用了结合8051CPU和RF收发器的CC2530芯片作为微处理器,CMX649作为语音编解码芯片,并采用协处理器辅助CC2530对语音信息进行处理,在lEEE 802. 15. 4协议上实现对语音的传输.详细介绍了系统的硬件和软件设计,对通话距离与通话质量进行了测试.实验结果表明:设计的语音通信机制具有较远的传输距离,能达到较好的语音传输效果,满足实际对语音通信的要求.

| Abstract: | Aiming at shortage of wireless sensor networks( WSNs)for voice transmission,design and implement a kind of wireless voice communication mechanism based on WSNs. Adopt CC2530 as microprocessor chip which integrates 8051 CPU and RF transceiver,uses CMX649 as speech codec chip,using coprocessor to assist CC2530 to process speech information,and realize voice transmission over procotol lEEE 802. 15. 4. Introduce design of hardware and software of the system in detail,and test distance and quality of voice communication. Experimental result show that this mechanism has far transmission distance,can achieve good voice transmission effect,meet the requirements of voice communication. |
