Research on Multilevel Distributed System Based on W77E58 for Community Health Monitoring / 医疗卫生装备

ABSTRACT

Objective To design a new multilevel distributed community-oriented health monitoring based on two serial ports MCU of W77E58.Methods Multi-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.
