摘要
本文介绍了一种新型的基于CC2430的穿戴式呼吸检测模块。模块通过CC2430触发了加载到两个检测电极上的高频激励脉冲。检测到的两个电极间的阻抗变化信号,通过滤波放大,送至CC2430进行模数转换,再利用ZigBee无线通讯单元把信号发送至上位机,实现了医护人员对病人的实时监护。该模块由单片机实现整体控制,采用ZigBee无线传输技术实现穿戴式检测,具有结构简单、成本低、功耗低、易使用等优点,还可以实现与心电检测共用检测电极,适用于家庭便携式监测仪器的开发。
This paper introduces a novel wearable wireless respiration detection module based on CC2430. In this module, CC2430 triggers the high-frequency stimulated pulse to load on electrodes. The signal, which is collected by the two electrodes and processed by preamp and filter, is sent to CC2430 for analog-digital conversion. Then, it is transmitted to central server by using ZigBee wireless communication module. It makes true that patients will be monitored in real-time by medical staffs. The module, which was controlled by MCU and integrated with wireless communication technology, has the characteristics of simple structure, easy to use, low-cost and low-power consumption. It also can share the electrode with the detection of ECG. The module introduced in this paper is fit to the design of home-based portable monitoring devices.
