基于CAN-Bus的医院病房全开放分布式监护系统

All Open Distributed Monitoring System of Hospital Wards Based on CAN-Bus

现场总线作为近些年来首先在工控领域发展起来的一种新型技术,目前尚未被广泛应用于医院病房监护领域。CAN(Controller Area Network)总线是被公认为最有前途的现场总线之一,其在病房监护全开放分布式系统中的应用,将具有很重要的现实革新意义。该文主要通过CAN总线实现中央监护站对病床现场监控器之间点对点的通信,从硬件的设计、软件的实现来完成系统功能。该系统通信设计简单易行,易于在医院内进行广泛的推广。

As a new-type technology which is firstly developed in the field of industrial automation in recent years,the fieldbus has not been widely applied in monitoring hospital wards.The Controller Area Network（CAN） is generally acknowledged as one of the most promising fieldbuses and its application in the fully open distributed system for monitoring hospital wards will have a critical significance to promote practical innovations.This article complete the faction of the system mainly through the CAN bus to realize central monitoring station site monitors sickbeds between point-to-point communication,added with the the design of hardware and the realization of software.The design of this communicatin system is simple and easy which can be widely promoted in the hospital.
