Description
Technical field
The present invention relates to a kind of system preventing rear-end collision.
Background technology
Knock into the back refer to the vehicle of same lanes trail and row time, the behavior that rear car front and the front truck tailstock bump against.Mainly due to follow-up spacing be less than minimum safe spacing and chaufeur delay of response or brake system performance bad caused by.Mention rear-end collision, a lot of chaufeur is all known, the chain reaction that the rear-end collision that motorway occurs produces is the strongest: because the speed of a motor vehicle is generally very fast, so once there be two cars to knock into the back, probably will involve a string below, this is namely called the common phenomenon of " bunching " by people.
In recent years, the express highway event of shunting into one another of getting on the car happens occasionally, extreme loss is caused to the lives and properties of people, trace it to its cause mainly due in the inclement weathers such as rainfall, mist, haze, sandstorm, the visbility of air reduces, when the vehicle in front is owing to collide or because after the reason stop motion such as car breaks down, vehicle below cannot be seen accident dangerous situation thus not have time enough to slow down outside safety distance, when seeing clearly again due to deceleration distance is too short also cannot positive braking, result causes serious consequence.
Motor traffic accidents is multiple, wherein rear-end collision accounts for sizable ratio, in fact when safety traffic, as long as the safety distance keeping at least with front truck, the occurrence probability of this type of traffic accident can be greatly reduced, but, roughly can only judge the distance whether safety of this car and front truck during existing running car by range estimation, so need a kind of automatic reminding system.
Summary of the invention
The object of the present invention is to provide a kind of system preventing rear-end collision, this system utilizes laser range sensor to obtain distance between this car and front vehicles, reminds this car chaufeur to slow down in time again according to this car speed of a motor vehicle simultaneously; Utilize laser range sensor to obtain distance between this car and front vehicle, remind front vehicle chaufeur the need of deceleration by the LED red light of this car tailstock.
In order to realize above object, the technical solution adopted in the present invention is: rear-end collision preventing system, it is characterized in that, comprise the first laser range sensor, the second laser range sensor, the 3rd laser range sensor, the 4th laser range sensor, speed sensor, button module, alarm module, LED red light module, display module and controller; First laser range sensor and the second laser range sensor are separately positioned on the dead ahead of headstock, and the 3rd laser range sensor and the 4th laser range sensor are arranged on the dead aft of the tailstock; The data of the first laser range sensor, the second laser range sensor, the 3rd laser range sensor and the 4th laser range sensor collection are input to controller; Button module controls the startup/be parked in of controller; Alarm module, display module are connected with controller respectively with LED red light module; LED red light module installation, at the tailstock, plays the object of reminding front vehicle chaufeur.
Optimal technical scheme, controller adopts AT89S52 single board computer; First laser range sensor and the second laser range sensor are separately positioned on left front and the right front of headstock, and the 3rd laser range sensor and the 4th laser range sensor are separately positioned on left back and the right abaft of the tailstock.
Compared with prior art, the invention has the advantages that: the present invention utilizes laser range sensor to obtain distance between this car and front vehicles, remind this car chaufeur to slow down in time according to this car speed of a motor vehicle more simultaneously; Utilize laser range sensor to obtain distance between this car and front vehicle, remind front vehicle chaufeur the need of deceleration by the LED red light of this car tailstock.
Accompanying drawing explanation
Fig. 1 is rear-end collision preventing system principle block diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
Fig. 1: rear-end collision preventing system, it is characterized in that, comprise the first laser range sensor, the second laser range sensor, the 3rd laser range sensor, the 4th laser range sensor, speed sensor, button module, alarm module, LED red light module, display module and controller; First laser range sensor and the second laser range sensor are separately positioned on left front and the right front of headstock, and the 3rd laser range sensor and the 4th laser range sensor are separately positioned on left back and the right abaft of the tailstock; The data of the first laser range sensor, the second laser range sensor, the 3rd laser range sensor and the 4th laser range sensor collection are input to controller; Button module controls the startup/be parked in of controller; Alarm module, display module are connected with controller respectively with LED red light module; LED red light module installation, at the tailstock, plays the object of reminding front vehicle chaufeur.
Wherein, controller adopts AT89S52 single board computer;
Display module adopts common LED display; Button module just adopt common can reset button; Alarm module adopts the buzzer phone of 5V to realize, and LED red light module adopts the LED glowed to realize.
AT89S52 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontroller, has 8K in-system programmable components flash storage.Use the manufacture of Atmel company high-density nonvolatile memory technology, with the instruction of industrial 80C51 product and pin completely compatible.On sheet, Flash allows program store in-system programmable components, is also suitable for conventional programming device.On a single chip, have 8 dexterous bit CPUs and in-system programmable components Flash, height is flexible, the solution of super efficient for numerous embedded Control application system provides to make AT89S52.AT89S52 has following standard feature: 8k bytes Flash, 256 byte RAM, 32 I/O mouth lines, WatchDog Timer, 2 data pointers, three 16 bit timing device/counting machines, one 6 vector, 2 grades of interrupt structures, full duplex serial port, crystal oscillator and clock circuit in sheet.In addition, AT89S52 can be down to the operation of 0Hz static logic, supports that 2 kinds of software-selectable select energy-saving mode.Under idle pulley, CPU quits work, and permission RAM, timer/counter, serial ports, interruption work on.Under power down protection mode, RAM content is saved, and oscillator is frozen, and all work of micro controller system stop, and interrupt or hardware reset until next.
Principle of work of the present invention: the first laser range sensor that this car headstock place is arranged and the second laser range sensor record the spacing of Ben Che and front vehicles, average and guarantee to measure accurately, determine to slow down the need of this car of warning reminding chaufeur according to the speed of a motor vehicle of this car simultaneously; 3rd laser range sensor and the 4th laser range sensor record the spacing between Ben Che and front vehicle, are reminded the chaufeur of front vehicle when spacing is less than safety distance time by the LED red light module at this car tailstock place; Button module controls the start and stop of controller; Display module shows the spacing of this car and front vehicles and front vehicle in real time.
