Medical Used Oxygen-measuring Network System Based on CAN BusAbstract:To charge exactly the oxygen that a patient consumes a time, hospitals need to measure the bulk of oxygen. The author presents a design of hardware and software of an Oxygen-measuring system which is based on can bus. CAN bus have integrate specialty of flexible and simple structure, high reliability, good adaptability, and easy maintenance, so it is used to meet the demands for real time performance of data communication. On-site data is transmitted to the host computer. The great ability of date processing of a personal computer is used for date record, query and printing in the system.
