摘　　要：随着无线通信技术的发展,适配多种应用场景的短距离无线通信技术应运而生。ZigBee技术是一种近距离、低复杂度、低功耗、低数据速率、低成本的双向无线通信技术。由于传输的时延不固定,ZigBee不适合实时语音通信。为改善时延问题,文章设计了一种以ZigBee芯片AT86RF231为通信芯片的语音对讲系统,使用芯片的MAC层和物理层,通过FPGA控制收发时序,实现了实时无线语音通信,满足了某系统的无线语音通信要求。With the development of wireless communication technology,short distance wireless communication technology that is suitable for various application scenarios has emerged.ZigBee technology is a bidirectional wireless communication technology that offers close range,low complexity,low power consumption,low data rate,and low cost.Due to the unpredictable transmission delay of ZigBee,it is not suitable for real-time voice communication.To improve the latency issue,a voice intercom system using ZigBee chip AT86RF231 as the communication chip was designed.Using the MAC layer and physical layer of the chip,real-time wireless voice communication was achieved by controlling the transmission and reception timing through FPGA,meeting the wireless voice communication requirements of a certain system.
