| 摘 要： | 针对目前交警使用手持式酒精测试仪,导致检查范围极为狭窄的缺陷,设计了车载防醉驾系统。利用32位的低功耗单片机MSP430F149为主控芯片,通过检测模块对对酒精浓度实时分析并送LCD12864显示,对酒精浓度超标则控制汽车点火并报警电路。仿真及实验电路的软硬件联合调试证明该设计能全面达到防止醉酒驾驶的目的,具有一定的实用性和推广价值。

| Abstract: | The traffic police commonly use handheld alcohol tester to check for drunk driving now, the disadvantage is that the examination scope is too small, sothe paper introduced the safety control system of preventing drunk driving.the core MUC was MSP430F149 which had high performance and low power consumption and cost. the system can automatically cut off the ignition of the vehicle, so we can achieve the aim of preventing drunk driving completely. |
