摘　　要：介绍了一种基于nRF24L01的无线温度采集控制系统的设计方案,阐述了系统体系结构及软、硬件设计。该系统在硬件上采用低功耗单片机ATmega16和2.4 GHz无线射频芯片nRF24L01设计,抗干扰能力强、可靠性高;在软件上采用时间片轮转法进行任务调度,实时性好、功耗低。测试结果表明,该系统控制方便、测量精度高、测温范围宽,能够可靠地实现温度的采集控制和无线数据的传输。A design scheme of wireless temperature acquisition and control system based on nRF24L01 was introduced and the architecture of the system and its hardware and software design were expounded. The system has strong anti-interference ability and high reliability by use of low-power microcontroller ATmega16 and 2. 4 GHz radio frequency chip nRF24L01 in hardware design and high real-time performance and low power consumption by use of method of time sliee round-robin in software design to realize multi-task scheduling. The test result showed that the system has easy control, high accuracy and wide temperature range, which can reliably realize acquisition of temperature and transmission of wireless data.
