摘　　要：针对传统心电监护装置电路结构复杂、体积大、携带不便等问题,设计一种高度集成的便携式无线心电监护系统。系统采用模拟前端SOC(System On Chip)芯片ADS1298作为心电信号(ECG:Electro Cardio Gram)测量的核心芯片,结合高速、低功耗的单片机STC12LE5A60S2以及无线传输模块,再将ECG数据传输给上位机,由Lab VIEW软件编写的程序完成ECG信号处理。测试结果表明,该系统具有电路结构简单、体积小,抗干扰能力强、便携式、高精度等优点,有利于对心血管疾病的院前发现、防治和远程诊治,同时降低了心源性猝死的发生率。In order to overcome the disadvantage of traditional ECG（ Electro Cardio Gram） monitoring system, which circuit structure is complex, the volume and weight is big, and is not easy to carry. A portable wireless ECG monitoring system was designed, which used the analog front-end SOC（ System On Chip） chip ADS1298 as the core chip of ECG measurement, combined with high speed and low power consumption MCU STC12LESA60S2, and a wireless transmission module. The ECG data was transmitted to the PC through wireless communication, in which the digital ECG signals was processed and displayed via an application software of LabVIEW. Results show that this system has some advantages such as simple circuit structure, small volume, strong anti-jamming capability, portable, high precision, etc. This system can play an important role in detecting and preventing pre-hospital cardiovascular disease, and reducing the incidences of sudden cardiac death.
