The automobile sells more than 80,000,000 every year , preserves and owns amounts are exceeding 600 million. The vehicle depending on using is crowded increasingly excessively, status cant exceed grave, being that up to but coming frequently smash up the accident, has brought about inevitable personnel casualties and economic losses. Automobile safety becomes a social problem , the occurrence rate for decrease automobile accident , the early warning system designing one kind of reliability height , responding to approximately and comparatively economical automobile anticollision is imperative, laser distance measurement is the most common one kind of one kind of automobile anticollision warning system it is the distance measurement making use of laser to design that from when distance measurement method , the main body of a book introduce that.That the thesis content is the design making use of development automobile of AT89S51 monolithic machine safety to warning system, is to make use of laser characteristic and advantage mainly, warning system combining laser distance measurement system AT89S51 monolithic machine being an integral whole , designing out one kind of laser distance measurement-based automobile safety. Be systems turn to adopt laser to sound a technology , be one kind of opto-electronic an integral whole of sound intelligence automobile anticollision product , send out a warning to during the period of the emergency being at a distance of with vehicle from when being smaller than safety appears, remind the pilot adopts the measure reducing the speed or braking, achieve effective the collision accident preventing from rear-ending happe
