Abstract This study is aimed to design a multiparameter monitor with multicommunication modes based on ARM. The control core of the system is an ARM9 processorS3C2440. This monitor can measure ECG, respiration, blood pressure, pulse, body temperature and blood oxygen saturation by designing physiological signal acquisition circuit, humancomputer interface circuit and communication interface circuit. Furthermore, this monitor can support three communication interfaces including WiFi, GPRS and DM9000, therefore it can communicate in different environment and condition. The system software was built by Linux and QT to realize physiological signal analysis, display and remote communication. Thirty subjects participated in the verifying experiments. Physiological parameters of them were measured with the monitor and other domestic monitor. Results showed that the verification accuracy rate of measurement reaches 92.2% to meet the clinical application requirement. Multicommunication methods can establish LAN and Internet connection conveniently, and provide condition for telemedicine and family care.
