摘要健康自古以来就是人们的生存追求之一。古代医疗条件落后，疾病常常引起人们的死亡，人类对如何预防疾病很关注，但是面对突如其来的病变却无能为力。因此如何预防疾病变得尤其重要。社会的不断进步，加之现今的竞争压力很大，在衣食无忧的年代人们对健康更加重视。移动通信的不断发展使得智能手机的使用越来越平凡和普及。智能手机内含有多种传感器，并且能够通过无线通信的方式传输所采集到的信号，其显示技术也是相当好，如今的手机屏幕越做越大。其所含有的蓝牙或WiFi可以十分方便可靠地传递信息。用户可以通过手机获得自己的血压数据。

该系统硬件部分主要包括数据采集模块、蓝牙通信部分和安卓手机硬件部分。信息采集模块主要负责人体血压的釆集并进行数据处理该模块的传感器电路能够采集血压测量时产生的振动信号。仪表放大器能放大所采集到的信号。高通滤波器，正向放大器和低通滤波器负责信号的处理。PIC16F877单片机控制数据的采集和传输。该单片机的A/D模块比较适合A/D转换。扩展的6264存储器模块能增大单片机的存储容量。传输模块由蓝牙通信电路和手机的通信模块构成。77643

软件部分分为数据采集模块软件和手机软件。数据采集部分软件能控制单片机进行A/D模块的转换并通过蓝牙传出数据。手机软件部分能够调动手机控制蓝牙进行数据的接收，向用户显示采集的数据并调动手机的通信模块进行数据的短信发送，使医务人员收到必要的诊断信息。

我国人口老龄化程度相当严重，人口众多，医疗资源却极为有限。希望此系统的出现能有效缓解医疗设备的稀缺。

Design of Blood Pressure monitoring System based on Smart Phone

Abstract Since ancient times, health is one of the pursuit of people's survival。 Ancient medical condition is backward, the disease often causes people's death, people are concerned about how to prevent disease, but in the face of sudden disease is powerless。 So how to prevent the disease becomes especially important。 The progress of the society, and the current competitive pressure, in the fullness of time people pay more attention to health。 With the continuous development of mobile communications, the use of smart phones is becoming more and more common and popular。 Smart phones contain a variety of sensors, and can transmit the collected signal through wireless communication, the display technology is also very good, and now the phone screen to do more。 The Bluetooth or WiFi contained in the model can be conveniently and reliably transmitted information。 This paper introduces a kind of measuring system of blood pressure and heart rate based on cell phone sensor。 The system mainly includes information acquisition module, data processing module, Bluetooth transmission module and Android smartphones, information acquisition module is mainly responsible for human blood pressure acquisition and data processing, transmission module using Bluetooth signal data transmission sent to the need for nursing staff in the terminal, and then through the Android phone use mobile network will include blood pressure information sent text messages to the hands of relevant personnel。 This greatly facilitates the patient's self health status, to facilitate the medical staff。 Control of lesions in the bud。       

Our country population aging degree is quite serious, the population is numerous, the medical resources are extremely limited。 It is hoped that the emergence of this 

system can effectively alleviate the scarcity of medical equipment。
