摘要
提出了一种基于MSP430单片机与NRF24L01+射频无线通信技术的可用于智能养老院系统终端的电路设计方案。该系统实现了以下功能:能够识别老人身份、紧急呼叫、摔倒报警、老人监控与定位。电路采用模块化设计,分别从电源管理模块、核心控制模块、射频无线通信模块、防摔倒模块、GSM通信与GPS人员定位模块这五方面描述了整个电路系统的硬件设计。经实际调试运行表明,识别距离可高达100m,且使用方便、稳定可靠、实用性强,具有很好的市场推广应用价值。
An MSP430 microcontroller-based and NRF24L01＋ RF wireless communications technology was raised and it can be used to design scheme of intelligent terminals of the circuit of the nursing home system.This system has realized following function：to distinguish the old person status,to localize and monitor their position and action outdoor,and make emergency call as their falling down or other dangeous situation.The electric circuit uses the modular design such as the power source administration madule,the core control module,the radio frequency wireless connection module,the module to guard against the old men following and the GSM correspondence and the GPS personal location modules.There are these five aspects to describe the entire circuitry hardware design.The experiment indicated that after actual debugging movement on line the recognition distance may reach as far as 100 m,and the system is easy to operate,stable and reliable in its practical application.
