【Abstract】 With the fast development of micro-controllers and micro-processors,the micro-controller are more and more integral,smaller and cheaper such that they can be widely used in the design and exploitation of small intellective electrical products.The object of the instant design is an intellective speed tester with a single-chip.In theory,the range of the speed testing is 0~360 km/h,so it can be used for real-time inspecting and recording the traffic,which has high precision and reliability and is suitable for outdoor work.更多还原
