基于蓝牙4.0和GSM的无线心率监测仪设计

针对现有的家用心率监测仪器便携性差、报警功能不完善、成本高等问题,提出一种基于蓝牙4.0 BLE协议栈和GSM移动通信网络的新型无线心率监测仪设计方案。系统可分为主机和从机两部分。从机由光电式脉搏传感器和蓝牙模块组成,负责测量心率和电量,并将得到的数据实时无线发送给主机。主机由蓝牙模块、单片机、液晶屏和GSM模块组成,负责接收从机发送的信息,并对数据进行监视,同时完成人机交互。实验测试表明,系统可稳定实现心率测量、监视、显示及远程设置、查询和报警功能,与市场上同类产品相比,具有使用便携性好、功耗低、测量准确、多重报警方式及成本低等优点,在家用智能监护领域具有广泛的应用前景。

Design of Wireless Heart Rate Monitor Based on Bluetooth 4.0 and GSM

Based on Bluetooth 4.0 BLE protocol stack and GSM mobile communication network, this paper proposes a novel design of wireless heart rate monitor to improve its portability, functionality and price competiveness on the market. The system can be divided into two parts, namely, master controller and slave detector. The latter plays a role of collecting data about heart rate and electricity quantity and sending them to the former by using a photoelectric pulse sensor and a Bluetooth module. The former, which includes a Bluetooth module, a microcontroller, a LCD screen and a GSM module, is responsible for receiving and analyzing the data from the latter and displaying the analysis results to users. The experimental tests show that this design presents an effective solution of heart rate measurement and monitoring, display, inquiry, alarm and remote setting. It has wide application prospects in the field of home intelligent monitoring because of its advantages such as easy portability, low power consumption, accurate measurement, multiple alarm modes and cheap cost compared to similar products on the market.
