摘要:: 针对传统的血压监护系统用户网络体验性差的问题，基于微信公众平台和嵌入式技术设计出一种智能移动血压监护系统。该系统的智能移动监护终端搭载PIC32MX微控制器，移植运行嵌入式Linux系统，可采集用户的心电、脉搏数据，并通过Internet将数据上传至接入微信的中心服务器，在微信中心服务器中利用脉搏波传播时间（PWTT）计算出实时的血压值。用户可以添加本系统的微信公众号，使用微信客户端查询监护结果。结果表明，该系统能够实现无袖带式连续血压测量,能够实现远程血压监护的功能，对慢性病的管理与治疗有重要意义。

Abstract:: A kind of smart mobile BP monitoring system based on WeChat public platform and embedded technology was proposed，aiming at the problem that the traditional mobile BP monitoring system had poor user experience, The smart mobile terminal of the system equipped with PIC32MX micro controller, transplanted embedded Linux system was ECG and pulse data of the user could be collected, then through the internet to upload data to the center server which accessed WeChat server,where using pulse wave Transit time (PWTT) to calculate the value of blood pressure in real time. Users could query monitoring results by WeChat client after paying attention to the system’s WeChat Subscriptions. Experimental results show that the system can continuously measure blood pressure without a cuff and the system can realize remote blood pressure monitoring, has important significance in management and treatment of chronic diseases.
