1、大连理工大学本科毕业设计(论文)基于nRF2401的无线远程监控系统RemoteWirelessMonitoringSystemBasedonnRF2401 学院(系):电气工程与应用电子技术系专业:电气工程及其自动化学生姓名:董琳琅学号:200485123指导教师:刘蕴红评阅教师:牟宪民完成日期:大连理工大学DalianUniversityofTechnology基于nRF2401的远程无线监控系统摘要近年来随着科技的飞速发展,远程无线监控系统在现代生活中不断成熟和完善。这个系统建立在无线收发模块PTR2000的基础之上。它是超小型,超低功耗,高速率无线收发数传模块,灵敏
2、度高,具有两个频道,特别满足需要多信道工作的特殊场合,它可完成点对点传输的数据采集,用于工业控制;数据采集;遥控;遥测;无线抄表;门禁系统;小区传呼;工业数据采集系统;小型无线数据终端;无线遥控系统;水文气象监控和机器人控制中。本文研究的远程无线监控系统是由PTR2000的无线收发系统、单片机AT89S51的下位机控制系统和LabVIEW的上位机监控系统构成的远程无线温度巡检系统。此系统可分为四个信息处理过程实现无线传输,首先通过ADC0809的模数信号的转换,然后信号传输到数码管显示电路,同时,单片机将信号传输给无线传输模块PTR2000。此片PTR2000再将信号无线传
3、输给与电脑相连的那片PTR2000,最后由基于LabVIEW的上位机监控系统进行监控。综上所述,本设计系统提出了一种简单,高效并且能够被广泛应用的远程无线监控体系。关键词:单片机;无线;远程;LabVIEW;nRF2401-I-基于nRF2401的远程无线监控系统RemoteWirelessMonitorSystemBasedonnRF2401AbstractWiththerapiddevelopmentofscienceandtechnology,RemoteWirelessMonitorSystemsarematuringandbecomingevermorepreva
