Development of Network Oxygen Flowmeter

SUN Hui-qin~1,LIU Nan-ping~1,JIA Hai-ying~1,LI Xin~2,CUI Yan-song~1(1.Tianjin Professional College,Tianjin 300402,China;2.Beijing University of Technology,Beijing 100088,China)  
The purpose of the development of network oxygen flow meter is to enhance the transparency of the hospital charge and make oxygen absorbed charge reasonable and open.The oxygen flow meter consists of some sets of apparatus,tributary ones of which can collect data through the infrared sensor and convey them to the central ones so as to measure the oxygen flow accurately.The system of the single chip AT89S52 of the central apparatus analyzes the data and shows the total amount and price of the oxygen consumption of each user with the monitor.As the tributary apparatus take the framework of distribution design, the final cost can be economized.The gathering cycle of the system's is 10 milliseconds,and display resolution is 0.1 L/min.It has the advantages of accurate and few error.
