呼出气体酒精含量远程监测系统的设计

Design of breath gas alcohol content detector remote monitoring system

设计了一种呼出气体酒精含量远程监测系统,该系统将手持式智能终端与呼出气体酒精含量检测仪通过蓝牙进行连接,引入正负压检测吹气、根据设备编号和身份信息核实被测试者身份、比对被测试者脸部图像与预置信息是否一致等采样防作弊设计以保证数据采集的可靠性,结合后台服务器的数据处理,实现了对被测试者呼出气体酒精含量的有效远程监测.实践证明,该系统操作简单、数据准确,对控制驾驶员饮酒行为、防止二次犯罪的发生有积极作用.

A breath gas alcohol content remote monitoring system was designed. The system connected hand-held intelligent terminal and breath gas alcohol content detector through the bluetooth,introduced preset sampling anti-cheating designs such as positive pressure and negative pressure blowing detection,verified subjects identity according to equipment number and identity information,and compared subjects＇ facial image with preset information to ensure the reliability of data collection. Combined with the data processing of backend server,the subjects＇ breath gas alcohol content remote monitoring was effectively realized. Practice proved that the system was simple in operation and accurate in data and it had a positive effect on controlling the driver＇s drinking behavior and preventing secondary crime.
