酒后驾驶监控系统车载终端电子标签的设计

为了对酒后驾驶做出有效的监管，提出基于RFID和GPRS的酒后驾驶监控系统。该系统利用车载终端的有源电子标签与周围部署的固定式或执勤交警手持的RFID阅读器进行通信，实现对酒驾车辆的智能识别和稽查范围内酒驾车辆拦截、追踪。但是有源电子标签寿命有限，因此系统仅在酒精检测模块检测到驾驶员酒精浓度超标时唤醒标签，有效降低了标签功耗，延长其使用寿命。

RFID Tags of Drunk Driving Monitoring System's Vehicle-mounted Terminal

In order to efficiently monitor drunk driving, a monitoring system based on RFID and GPRS is put forward. The system uses the alcohol detection module to test alcohol concentration of the drivers. The active RFID tags can be waked from the power down mode to communicate with the RFID readers that can be deployed fixed in somewhere or in the hands of the traffic police on the duty in order to realize the intelligent identification of the drunk driving vehicles as well as the intercept and trace of the drunk driving vehicles within the scope of the polices inspection. Because of the finite life of the active RFID tags, the system only wakes the tags up when the alcohol detection module detects that the alcohol concentration is out of limits which can reduce the tags power consumption efficiently and prolong the tags service life.
