为满足医院船医疗设备数据的实时传输要求，提高系统吞吐能力，设计基于无线网络的医院船医疗设备数据采集和传输系统。构建医院船医疗设备数据采集和传输系统总体框架，基础层的数据采集终端利用条码扫描检测单元、电压和电流互感器、温湿度传感器采集医院设备数据，经放大滤波电路、A/D转换器获取其量测值后，由单片机完成数据打包，通过无线传送单元将其传输至数据处理层实现数据抽取、清洗等处理，网络层的无线自组网络通过路由模块调用基于MinACK的路由算法完成医疗设备数据的传输，由用户层的客户端服务器完成数据的分析、查询、存储等。实验结果表明：该系统可采集呼吸机设备功率数据、各数据段包含数据包数量为40时，系统吞吐能力最突出；用户层客户端服务器可实现UT5321设备数据的查询。
The data acquisition and transmission system of hospital equipment based on wireless network is designed to meet the real-time transmission requirements of hospital equipment data and improve the system throughput. Build the overall framework of data acquisition and transmission system for large ship hospital equipment. The data acquisition terminal of the basic layer uses barcode scanning detection unit, voltage and current transformer, temperature and humidity sensor to collect the data of hospital equipment. After the measured value is obtained by amplification and filtering circuit and A/D converter, the data is packaged by the single chip computer and transmitted to the data processing layer through wireless transmission unit for data extraction, cleaning and other processing. The wireless ad hoc network in the network layer uses the routing module to call the routing algorithm based on MinACK to complete the transmission of hospital equipment data, and the client server in the user layer completes the analysis, query, storage, etc. of the data. The experimental results show that the system can collect the power data of ventilator equipment, and when the number of data packets contained in each data segment is 40, the system throughput capacity is the most prominent. The user-layer client server can query the UT5321 device data.
