Design of data acquisition and monitoring system for ventilator / 医疗卫生装备

ABSTRACT

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.
