因国家规定呼气的酒精浓度超过0.15mg/L为酒醉驾车,本研究利用酒精传感器及嵌入式系统设计,如果系统侦测到驾驶者在密闭的汽车内驾驶者酒精浓度未超过0.0073mg/L,驾驶能够顺利发动汽车引擎。若呼吸的酒精浓度累积超过预先设定的0.0073m... 因国家规定呼气的酒精浓度超过0.15mg/L为酒醉驾车,本研究利用酒精传感器及嵌入式系统设计,如果系统侦测到驾驶者在密闭的汽车内驾驶者酒精浓度未超过0.0073mg/L,驾驶能够顺利发动汽车引擎。若呼吸的酒精浓度累积超过预先设定的0.0073mg/L安全值时,汽车引擎无法启动;行进中的汽车,侦测到驾驶者酒精浓度超过0.0073mg/L,系统会自动启动闪烁汽车四个角落的方向灯,并以控制汽车引擎,将汽车时速下降到20(公里/小时),并发出语音警示,提醒汽车驾驶人汽车将于系统设定的固定时间(例如3分钟)内熄火,请车主尽速将车辆开到路旁停车,以确保行车安全。 展开更多

Beginning with the analysis of the behavior of natural ants, this paper illuminates the principle and method that, by adopting image texture energy as pheromone and finding their way on the track of the pheromone, artificial ants have the ability to identify and remember through similar measurement of pheromone. Based on the quantity of experiments, this paper analyzes some factors that influence the ability of artificial ants and draws some conclusions about the law of ant perception. 展开更多
