摘 要:针对当前矿用语音通信系统的不足,提出了一种基于IEEE 802.15.4协议标准的矿用语音通倌系统设计方案,给出了无线语音通信终端的软、硬件设计;语音通信终端采用CC2530作为处理器芯片,利用CSP1027对语音信号进行A/D或D/A转换,并采用AMBE语音编解码技术对量化后的语音数据进行编解码,在无线通信协议IEEE 802.15.4标准上实现各节点间语音信息的双向无线传输;实验测试结果表明,语音通信设备在有电磁干扰及障碍物的环境下,其有效通信距离为37 m,在有效通信距离内具有语音清晰、通话可靠,满足语音通信要求。For overcoming disadvantages of the present mine voice communication system, a kind of wireless voice communication system based on IEEE802.15.4 is put forward. The paper provides detailed information about hardware and software of the wireless voice communi- cation terminal. It adopts CC2530 chip'as a processor, speech signal is AD or DA convented by CSP1027, and encode or decode quantized voice data by AMBE voice codec technology, and realize voice message two--way wireless communication over the protocol IEEE 802.15.4 between voice communication terminals. The tests show that voice communication device' s effective communication distance is 37m in the environment with electromagnetic interference and obstacles, which can get a clear voice and have a high reliability in the effective distance of communication, meet the requirements of voice communication.
