呼吸机数据采集监控系统设计

Design of data acquisition and monitoring system for ventilator

目的 :设计一种独立的呼吸机数据采集监控系统,为工程师检修呼吸机提供方便、可靠的参考信息。方法 :该系统主要分为数据采集与监控2个模块。其中,数据采集模块选用MSP430F149单片机作为主控芯片,实现装备运行数据的实时采集与存储;监控模块则选用STM32单片机作为主控芯片,实现装备监测、控制服务器串口转换及其数据通信功能。运用无线模块NRF24L01实现采集模块与监控模块之间的数据无线传输。结果:该系统实现了对呼吸机运行日志信息的实时采集与存储,能够将采集到的数据信息完整地传输至服务器,以供工程师查看。结论:该系统克服了人工采集静态输入的缺陷,可以进行基本的风险分析,有助于工程师了解呼吸机运行过程中的状态,对工程师的监测、维修工作具有很好的指导意义。

Objective To design a data acquisition and monitoring system to facilitate the maintenance of the ventilator.Methods The system was composed of two modules of data acquisition and monitoring. The data acquisition module used MSP430F149 SCM as the master control chip to realize real-time acquisition and storage of operation data, and the monitoring module adopted STM32 SCM as the master control chip to implement equipment monitoring, server serial port conversion and data communication. Wireless data transmission between the two modules was executed with wireless NRF24L01 module. Results The system realized real-time acquisition and storage of the ventilator log, and transmitted acquired data to the server. Conclusion The system eliminates the deficiencies of manual operation and implements basic risk analysis, and facilitates the engineer to monitor and maintain the ventilator.
