摘要
为了实现战场上语音和数据的近距离无线传输,将语音传输与ZigBee无线网络相结合,利用ZigBee技术设计一个小型的无线网络,代替有线通信方式.以IAR的Embedded Workbench为开发平台,设计了控制模块、语音模块、无线通信模块、功率放大模块、数据接口等模块硬件电路.采用RALCWI语音压缩算法保证话音质量,设计了2.4GHz ZigBee网络节点,组成2.4GHz ZigBee小型网络,在网络内自由传输语音和数据,并在软件上实现了语音处理和组网、无线收发数据、数据传输等功能,解决了战场上无线传输的问题.
In order to achieve the close wireless transmission of voice and data in the battlefield, the paper combines voice transmission and ZigBee wireless network, and design a small wireless network to substitute of wired communication. IAR＇s Embedded Workbench was used as the development platform, and control module, voice module, wireless communication module, power amplifier module and data interface module were designed. RALCWI voice compression algorithm was used to ensure voice quality. Several 2.4 GHz ZigBee network nodes were developed and a 2.4 GHz ZigBee Small network was constructed. Voice and data could be free transferred in the network. The functions of voice processing and networking, wireless data transceiver, data transmission are also realized by software. The problem of wireless transmission on the battlefield is solved.
