Development of Parameter Measuring System for Oxygen Supply Unit in Lowpressure Chamber / 医疗卫生装备

ABSTRACT

Objective To develop the measuring system used for the parameters of onboard oxygen supply equipment in the hypobaric chamber. Methods The programmable controller was applied to acquisition, processing and analysis of the data from the sensor. The host computer was used to accomplish control and information display. Results The system could display the parameters through digital, simulating meters, and recording curve. The numerical value in the recording curve was marked by the date and time. All data were saved in the computer for futural analysis and procession. Conclusion The measurement system of oxygen supply parameters can satisfy the desired requirements for the performance and precision.
