摘要
由于现有无线传感器节点采用的单片机运行速度慢和程序存储空间小,影响了节点功能的扩展,本系统以STC12C5A60S2单片机为核心部件,利用无线数字传输芯片nRF24L01和温度采集芯片DS18B20构成了无线数据传输系统.重点讨论了系统的硬件和软件设计要点,给出了硬件接口电路,控制系统的主程序流程,以及主要程序代码.运行表明,该系统控制方便、工作稳定,能实现可靠的无线数据传输.
As the single chip of the existing wireless sensor nodes have slow speed and less program storage space,affecting the expansion of the nodes＇ function,the wireless data transmission system which was based on single chip STC12C5A60S2,and composed of wireless data transmission device nRF24L01 and high-precision 1-wire bus digital temperature sensor DS18B20,was introduced in this paper.The hardware and software design of the system was explained in detail.The interface circuit,main program flow chart and main program code of the system were introduced concretely.Actual operation showed that this system was easy to control and stable,and could perform reliable wireless data transmission.
