摘　　要：目的:设计一种基于双串口单片机W77E58的面向社区健康监测多级分布式系统。方法:采用RS422串行接口标准实现多机间全双工高性能串行通信方案,主要由生理参数检测、处理模块、数据通信模块以及上位机显示处理模块等几个部分组成,通过系统功能模块各部分的连接及软硬件设计,实现面向社区多级分布式健康监测。结果:RS422作为一种硬件设计简单、控制方便、成本低廉的通信方式,实现了这些模块的统一协调通信,实现一主(PC)多从(单片机系统之间的通信)的三级集散式测控系统。结论:提供了一个低成本、高性能的面向社区健康监测的解决方案和实现形式,可以很方便地运用到家庭移动监护中。Objective To design a new multilevel distributed community-oriented health monitoring based on two serial ports MCU of W77E58. Methods Muhi-machine serial communication with high-performance and full-duplex was realized by using the standard RS422 serial interface, which involved several parts in, such as detection and processing module of physiological parameters, communication module and display processing module of the host computer. With the different functional modules and software and hardware connection, multilevel distributed health monitoring was realized. Results RS422, being a simple, easy to control and low-cost communication mode, implemented the communication between these modules. Finally, the distributed measurement ＆ control system with one PC and several MCU systems was implemented. Conclusion A low-cost, high-performance community-oriented health monitoring solution was realized, which can be easily applied to mobile monitoring at home.
