Design Of Portable Remote Multi-Monitor Based On ARM9

With the development of material civilization and people's demand of medical care increased, the portability and flexibility which people require are also getting higher and higher. Developing monitoring system which appropriate community and home has become the trend of monitoring system. Based on this, we have studied the portable remote multi-monitoring system.The portable remote multi-parameter monitoring system mainly consists of control module,physiological signal acquisition module,memory module,display module and GPRS communication module and so on.To begin with, the acquisition module of physiological signal completes the acquisition of ECG, blood pressure, body temperature and other physiological signal,and makes AD conversion. Then the system processes and analyzes the signals which we get. Finally, telecommunications is done by GPRS communication module.The system uses Samsung S3C2440 processor as a host and embedded Linux as the operating system.System interface is made by Qt/Embedded development tools.We get R-wave of ECG and width of QRS by difference algorithm.Then we achieve compression of ECG by wavelet technology.Through experiments,the system runs stable in line with the expected design requirements.
