摘　　要：为了解决无线传声器功耗大、抗干扰能力差等问题,提出一种基于nRF24Z1为核心的低功耗无线传声器的设计方案。首先分析数字无线通信系统的模型,给出了无线传声器的整体结构图,然后详细介绍各部分的软、硬件设计方法,最后根据要求设计出符合本系统的天线。结果表明:该方案可有效地降低系统的功耗,可连续工作20h,满足设计要求。In order to solve the power wireless microphone and anti-poor capacity, a core based on the nRF24Z1 for the low-power wireless microphone design is designed. The digital wireless communication system model is analyzed, and the structure of the wireless microphone is given. The hardware and software design methods are introduced in detail. Finally, the antenna in accordance with requirements of the system is designed. The results show that the system power consumption can be reduced effectively and 20 hours of continuous work can meet the design requirements.
