摘要：

目的为构建一个医疗物联网的平台，实现患者与医生远程、实时沟通与治疗，本文设计了一个便携式
、实时的多参数生命监护仪，以实现心电、呼吸、血氧、脉搏、跌倒、体温的实时监护。方法该系统电路
部分采用双层设计，下层为多参数生理信号采集板，上层为cc2430单片机。下层用于各个生理参数的采集，
上层利用zigbee模块进行生理数组的传输。在数据采集的同时运用信号处理算法对采集到的生理信号进行预
处理并提取特征，进而计算诊断参数并做初步的诊断。最后将初步诊断结果通过cc2430的zigbee模块传送到
家庭网关，并通过Internet将数据传送到远程医疗站，待医生给予进一步诊断。结果经测试该监护仪成功
实现了多生理参数采集及实时处理。结论该多参数生命监护仪可实时监护患者动态并成功运用到医疗物联
网中。

Objective In order to build a platform of medical internet of things to make
doctors and patients exchange the therapeutic information in a long-range and real-time way,
the multi-parameter life monitor represented in this paper can realize real-time monitoring of
electrocardiograph (ECG), respiration, blood oxygen, pulse, fall behavior and body
temperature.Methods A double-layer structure is adopted, the lower layer is signal acquisition
board and the upper layer is cc2430 microcontroller.Real-time signal algorithms which include
signal preprocessing, characteristic wave detection and parameter calculation, are used in the
monitor.Then the parameters are used to form a tentative diagnose.Finally, the tentative
diagnose is delivered to cc2430 and transmitted by the zigbee module of cc2430 to the home
gateway.The home gateway is responsible for transmitting the tentative diagnose to the remote
medical station and waiting for a further diagnose from the doctor.Results The monitor
successfully implements the acquisition of physiological signals and the real-time processing
of signals.Conclusions This multi-parameter life monitor can monitor the patient in a real-
time way and can be successfully applied to the medical internet of things.
