The design of Wireless Multi-patient Electrocardiogram Monitor Based on ARM9 Wang Ning-ning Zhao Qiu-sheng Wang Shen Li Guan (Department of Biomedical Engineering,Tianjin Medical University, 300070 ) Abstract: Objective To design a portable multi-patient wireless electrocardiogram(ECG) monitor with small volume and low power consumption. Methods S3C2410 which based on ARM920T was used as system controller,and wireless transmission chip nRF401 was used to transmit ECG data. The software was designed on WindowsCE embedded operating system,to control the process of transmission and the analysis and disposal of electrocardiosignal. Result The monitor can guard 12 patients at the same time and it's real time. Conclusion The monitor with small volume and low power consumption is convenient to take with patient and never influence their normal activities. Multithreading programming was used to monitor multipatients, which increased the whole response speed and advanced the efficient of the system.
