摘　　要：以美国德州仪器公司最新双核处理器OMAP3530为核心设计了一个新型多参数监护仪,用于监测人体心电、血氧饱和度、无创血压、呼吸及体温等生命体征参数.重点讨论了基于小波变换的心电检测算法,简要介绍其他参数采集模块.样机测试结果表明,该监护仪系统性能稳定,能实时监测和远程传送,正确完成对各项生命体征参数的监测.A new multi-parameter monitor with Texas Instruments latest dual-core processor OMAP3530 was presented. The monitor is for detecting and processing five life parameters, i.e. , electrocardiograph, oxygen saturation, blood pressure, respiration and body temperature. An algorithm based on wavelet transform for detecting electrocardiograph signal was discussed in detail. The brief introduction of other parameter acquisition modules in the monitor was also included. Experiment results have demonstrated that the performance of the monitor is desirable and the detection accurary of five life parameters satisfies the design requirement.
