摘要
针对矿井下通讯的特殊要求,通过采用时分多路技术和制定合理的通信协议,本文研究利用SPCE061A单片机的语音功能和nRF2401A无线收发芯片的2个通道可实现点对点的呼叫和点对多点的广播功能,设计了一种可用于矿井紧急通讯的无线双向语音系统,对系统的软件和硬件进行了设计。该系统的实际运行结果表明,系统布设方便、成本低、可靠性高,能满足矿井紧急通讯的需要。
According to the special requirements of mine communication, the paper designed a wireless voice system for mine emergency communication by using the technology of TDMA and constructing the reasonable communication protocol, which combines voice function of the single chip SPCE061A with two-way radio voice transmission point-to-point calling and point-to-multipoint broadcasting function of the wireless transceiver chip nRF2401A. The hardware and soft-ware for the system have designed. The results of working process show that the system presents convenient deployment, low cost and high reliability. Thus the design proposed in this paper meets the need of mine emergency communication.
