具有自定位功能的便携式一氧化碳检测装置

The portable carbon monoxide device with self positioning function

设计了一种具有自定位功能的便携式一氧化碳检测报警装置.该系统通过三电极电化学传感器7E/F和GPS模块LEA-5S对一氧化碳气体浓度和装置地理位置进行测量,电化学传感器输出的电流信号经调制后进行AD转换,微处理器ARM芯片通过数据分析处理,完成一氧化碳浓度判断,并通过GPRS实现对一氧化碳浓度、报警信息和装置地理位置信息的远程无线传送.基站总机根据一氧化碳浓度、装置地理位置信息、预判断事故类型及程度,为安全、准确救护提供保障,弥补了工业常用检测装置不能提供远程事故报警和详细救护地址的不足.

In order to overcome the carbon monoxide detection device that it can not realize the staff accident a- larm and provid accurate ambulance address, a remote and portable alarm device with self positioning function is designed. Electro-chemical sensors（TE/F）is adopted by this system to sample the concentration of carbon mon- oxide, and the data of the geographical location that comes from GPS is modulated and sent into the ARM wafer. The carbon monoxide concentration is analyzed by means of the ARM wafer and the data could be sent and the device could give alarm locally or remotely. The base station operator provide accurate rescue according to the concentration of carbon monoxide and personnel location information.
