基于ARM的人体表面温度测控系统设计

The Measurement and Control System of Shell Temperature of Human Body Based on ARM

针对手术过程中人体的低温现象,开发一种基于ARM9 2440嵌入式处理器的、以人体表面温度为控制对象的表面温度控制系统。系统由多路人体表面温度检测模块、触摸式显示控制模块、气体温度检测及加热模块、气体流量检测及输送控制模块等构成。对系统核心模块的功能和效果进行试验,结果表明,在手术中可以根据人体表面温度的实时变化情况,控制吹拂在人体表面的气流温度和流量,达到使人体核心温度稳定的效果。

Aimed at the hypothermia during the medical operation a control system of shell temperature of human body was developed based on ARM9 2440 embedded processor, which consisted of several intelligence control modules such as a muhi-chanel temperature detection module, a touch sensitive display and control module, an air temperature detection and warming module, a air flux detection and control module, etc. Experiments were carried out to validate the core modules. The results show that the core temperature of human body can be maintained by controlling the temperature and air flux onto the human skin according to the instant shell temperature.
