基于CC2530的重症监护病房环境实时监测系统设计

Design of Real-time Environment Monitoring System in ICU Based on CC2530

摘要:

为了实时监测ICU(intensive care unit)病房环境中湿度、温度及CO₂浓度等环境信息,设计了基于CC2530的重症监护病房环境实时监测系统,系统由重症监护病房环境感知节点、网关节点、监控终端等几个部分构成；以CC2530为主处理器完成对感知节点的软、硬件设计,根据重症监护病房湿度、温度及CO₂浓度等环境信号的特点,设计各传感器模块的驱动电路；在Z-STACK协议栈的基础上,设计感知节点软件,实现数据的转发；经测试,网关节点的收包率在80%以上,预警信号产生时间小于3 s,监控终端数据刷新能力强,该系统具有精确度高、实时性强、预警及时等特点。

Abstract:

For monitoring the real-time environment information including humidity, temperature, CO2 concentration in ICU, the real-time environment monitoring system in ICU has been designed. This system consists of environmental monitoring node in ICU, gateway node, the monitoring terminal. On the basis of CC2530, the software and the hardware of monitoring node have been designed. According to the characters of humidity, temperature, CO2 concentration in ICU, the drive circuit of each sensor module is designed. By using the Z-STACK, the software of monitoring node is designed to transmit the collected environment data. The test results show that reception rate of the gateway node is more than 80%, generation time of warning signals is less than three seconds and monitoring terminal has strong ability to refresh data. The system has characters of high accuracy、good real-time performance and timely warning.
