摘 要

随着我国医院系统的现代化、科学规范化及信息化的深入，医院用氧时提出了集中管理和信息化管理的要求，由此需对各科室、病床用氧量的精确计量要求，并对检漏方式提出更高的精度要求，不仅要求对实时监测各科室、病床用氧的需求量，而且需要对输送过程中存在泄漏问题的及时监测，但在原有线路上改造的成本太高，而且多有不便，所以本文研究了该系统，基于ZigBee无线网络的传感器测量各病区的氧气流量，便于医院制氧室对各病区氧气使用情况进行监控、统计和分配，采集分布在各科室、病床供氧管路上的氧气流量计测量到的流量信息，实现对全院氧气使用情况的实时计量、保存、查询和管理，同时通过流量的计算来监测输氧管路的泄漏情况。

本文对无线传感网络组网进行研究:

设计出满足医院氧气流量计量系统的无线传感网络；

设计采集节点(氧气流量计端)的数据接口电路，满足无线数据传输要求；

使用MFC编制医院氧气流量计量系统应用程序，实现在监测计算机上的氧气流量信息的采集、存储，实现可视化、形象化的人机界面，使操作者易于对各个科室氧气量数据的查询与实时观察。

Hospital oxygen flow measurement system based on Wireless Sensor Network

Abstract

With the development of the modernization, the standardization of science and the information technology of hospital system in our country,the requirements of centralized management and information management are put forward for the using of oxygen in hospital. So it is necessary to measure the precise oxygen using of each department and hospital bed and put forward to the higher accuracy of leak detection. There are not only the requirements for real-time monitoring of oxygen demand in various hospital beds, but also for monitoring the leakage problem in the process of transportation. The cost of the transformation of the original line is too high and it is inconvenient, so I study the system based on ZigBee wireless network measuring the ward flow of oxygen. For hospital oxygen chamber of the ward oxygen usage monitoring, statistics and distribution. By collecting the flow of information in the various departments, as well as the bed oxygen pipeline oxygen flow meter, we can realize the real-time measurement of the use of oxygen,saving,query and management, also monitoring the oxygen pipeline leakage through the calculation of flow.

This article conducts the research to the wireless sensor network:

Designing the hospital oxygen flow measurement system based on wireless sensor networks.

Designing the data interface circuit collection (oxygen flowmeter end) node, meeting the requirements of the wireless data transmission;

Using MFC to compile the hospital oxygen flow metering system application, realizing the monitoring of oxygen flow information collection, storage, visualization, visualization of human-computer interface, so that it is easy for the operator to measure the amount of oxygen data query and real-time observation.
