酒后驾驶无线报警系统设计与实现

Design and realization of a radio-alarm system to detect drinking driver

详细介绍了将检测技术与无线通信技术用于预防酒后驾驶系统的设计方法。系统选用半导体型酒精传感器完成对司乘人员呼气的酒精检测,经放大、比较和判断,通过编程把判断结果分别形成语音预警信号,再利用公用通信网(G网、CDMA或固定电话网)把语音预警信号传送给车主或乘客。测试结果表明,对司乘人员的饮酒情况判定准确,接收的语音信号清晰可靠。证明了该设计方法的有效性和可行性。

This paper specifies an approaches to carry out a system, which is applied to avoid drunk driving by mixing detection technology with wireless telecommunication technology. The semiconductor-based alcohol sensor is selected to complete alcohol detecting of the driver’s breath. The detected signal is enlarged and compared to be made a three-grade judge. The judge signals is then programmed into voice warning signals respectively, which is finally transported by radio on the public communications network to remind the owners of the taxi and customers. The test results indicate that the judge for the driver’s drinking station is correct and voice signals received by the owners of the taxi and customers are reliable and clear. It shows that this design method is effective and practicable.
