Design of Multi-parameter Monitoring System Based on Embedded Linux+Qt / 中国医疗器械杂志

ABSTRACT

OBJECTIVE@#To establish the system software of multi-parameter monitoring by embedded Linux kernel and Qt library.@*METHODS@#To determine the hardware system needed for the development of the system, carry out system Bootloader (Bootloader), Linux kernel, file system and Qt/Embedded (QtE) tailoring and transplantation and application development on the basis of the hardware system, and achieve the characteristic UI design.@*RESULTS@#The changes of physiological parameters were observed in real time to improve the stability and real-time performance of the whole system and increase users' experience with QtE.@*CONCLUSIONS@#The embedded Linux+Qt multi-reference monitoring system can improve the stability, operability and functionality of real-time monitoring and multi-physiological information, and has good extensibility and maintainability.
