Design and Implementation of a Digital Telemetry ECG Monitoring System

提出的遥测心电监护系统采用蓝牙无线技术监测病人的心电等生理参数,克服了使用传统的有线系统及病人不能自由活动的缺点。系统的发射机主要由蓝牙模块ROK101007和带有8通道12位A/D转换器的微控制器ADuC812组成,ADuC812主要进行心电数据的采集和控制,两者之间通过UART接口进行指令和数据的传输。接收机通过USB接口与PC机或者笔记本电脑实现高速数据通信而不需要外加工作电源。试验表明,该系统能有效地无线传输心电数据。

The primary aim of this system is to monitor the health of the patient using Bluetooth wireless technology with respect to specific parameters such as heart and the ECG. This overcomes one of the drawbacks of the current system, which is not suitable for an ambulatory patient since the patient is wired into the system. Its telemetry transmitter is implemented using a ROK101007 Bluetooth module and an ADuC812 micro-controller. The ADuC812 provides an 8-channel 12-bit resolution A/D converter. It primarily realizes ECG parameter collect and control. Communication between the Bluetooth module and the micro-controller is carried out via UART interface. Its receiver can realize high-speed data communicating with the PC and the notebook computer through USB port without extra operation power supply. In the test, this telemetry ECG monitor can be used for ECG data effectual transmission.
