基于MSP430单片机的无线距离系统课程设计论文.doc

Hefei 课程设计 项目报告 项目名称：无线距离报警 无线距离报警 摘要 本无线距离报警是以MSP430F1232超低功耗单片机作为主控核心和无线通信模块nRF2401的各个功能模块及其特性。系统主要实现了无线距离报警即当从机离开主机一定距离后主机会自动报警，并且在报警发生后可有用户通过按键对报警状态进行清除，另外从机还预设了内线的掉线检测，即主从机在正常通信的状态下，从机会实时将自身的一根内线信号上传给主机并伴有灯光报警提示。分析了数据发送和接收的工作原理以及实现本系统所要解决的关键问题最后通过实物验证了系统的性能。 关键词：单片机MSP430?、NRF24L2401、无线通信 、报警???
