Objective:To design and research a life information management system based on LabVIEW for gathering,processing,extracting and displaying physiological sign signals that detected by monitoring terminal of wearable device so as to carry out corresponding guidance of rescue for care staff.Methods:Progressive structure was adopted in the design,and TCP/IP protocol of LabVIEW was applied to construct receiving module of physiological sign signals.Based on above results,a series of processes included of body temperature,electrocardiogram and blood oxygen saturation were achieved.And the method of wavelet transform was used to reduce noise for electrocardiogram signal.Results:Through received physiological signal of slave computer and carried out process of reducing noise for it,the system achieved experiment of non-invasive measurement on the detection of blood oxygen saturation.Therefore,it could meet the requirement of care staff.Conclusion:The system has realized the process for physiological sign signal through the module of LabVIEW,and it also has achieved the storage and read for these signals.Therefore,it can take the obtained data to reach the expectant effect.
