Description
Technical field
The present invention relates to anti-collision safety system for automobile fields, and in particular to a kind of pre- based on millimeter wave tailstock anti-collision of caring the car
Alert system and its method for early warning.
Background technology：
By the high speed development of last decade, by the end of the year 2010, national highway is open to traffic total kilometrage up to 7.4 ten thousand public affairs
In, it is only second to the U.S., occupies the second in the world.Currently, with the rapid growth of China's highway mileage open to traffic, road service year
The increase of limit, China's highway have been enter into the period that construction is laid equal stress on maintenance, more than the 10000 kilometers of high speed built up before 2000
Highway enters overhaul time comprehensively, and more than the 50000 kilometers of highway built up before the end of the year 2008 also generally enters defects liability period
Normal maintenance curing period afterwards, workload is increasing, and technology content is more and more high, society to express way driving safety and
Comfort require it is also higher and higher, for this reason, it may be necessary to reinforce expressway maintenance management, grasp in time various diseases situation and at
Cause, correct selection use maintenance and repair technology and method, carry out maintenance in due course, with ensure to provide safety, quickly, it is economical,
Comfortable modern transportation condition.
About when the November in 2017 of afternoon 14 on the 24th, motor bus and a special Operation Van (road surface on the highway of sea village
Cleaning roads are cared the car) bump against the dead 6 people injury of 1 people of cause.About when 3 days, afternoon 15 on the 27th, in rotary island western line high speed Sanya
Precipice city section, minibus and road-maintaining truck, which bump against, causes 3 people dead.In 4 days, on the highway in Hainan running fire 2 be related to road
The dead traffic accident cared the car, miserable accident set people thingking.November 28, reporter has visited Haikou urban district, highway etc.
Section is found, is come with some shortcomings really in terms of safeguard procedures of the road-maintaining truck in operation, the in addition traffic of rear car driver
Awareness of safety is also most important, has only carried out " double shield ", has just been avoided that accident.
Therefore it cares the car below plus warning is extremely important, place cone cylinder in advance or just in the mark of operation slow down,
Or back car can be reminded, but we do not see these warning marks sometimes, even if having on vehicle body warning arrow or
One slight warning lamp, much looks over daytime, still not apparent enough.
Invention content
It is cared the car tailstock anti-collision early warning system and its method for early warning based on millimeter wave the purpose of the present invention is to provide a kind of,
To solve the above-mentioned many defects caused by the prior art.
One kind is cared the car tailstock anti-collision early warning system based on millimeter wave, including millimetre-wave radar, center processor, acousto-optic announcement
Warning lamp and anti-collision early warning display screen, millimetre-wave radar is mounted on the tail of the body of highway maintenance vehicle, for detecting front vehicle
Distance and speed；Center processor is mounted on highway maintenance vehicle and is electrically connected with millimetre-wave radar, for detecting millimeter wave
The signal that radar transmissions come, and handled；Audible and visual alarm lamp be mounted on highway maintenance vehicle tail of the body and at center
It manages device to be electrically connected, for alerting front vehicle driver；Anti-collision early warning display screen is mounted on the tail of the body of highway maintenance vehicle
And with center processor be electrically connected, distance and speed for showing front vehicle, and remind front vehicle take care away from
From.
Preferably, the millimetre-wave radar is postposition radar, active probe front vehicle, frequency 77GHZ, detection range
200m can send out early warning when front vehicle has 200m away from highway maintenance vehicle.
It is a kind of to be cared the car tailstock anti-collision method for early warning based on millimeter wave, include the following steps：
Highway maintenance vehicle, which is in, first executes task status, and millimetre-wave radar is in open state, when front vehicle distance
When the distance of highway maintenance vehicle reaches 200m, center processor can receive the signal that millimetre-wave radar monitors；
Then center processor handles received signal, and calculates between front vehicle and highway maintenance vehicle
Real-time range, and the numerical value of real-time range is transferred on anti-collision early warning display screen, anti-collision early warning shows screen display rear vehicle
Instant distance with highway maintenance vehicle, and center processor sends out alarm command, audible and visual alarm lamp to audible and visual alarm lamp simultaneously
It can carry out flash of light early warning and sound early warning；
If the driver of front vehicle carries out deceleration-operation later so that front vehicle is big at a distance from highway maintenance vehicle
When 200m, millimetre-wave radar detects the position less than front vehicle, and center processor, which can be sent out, stops alarm command to sound
Light warning light and anti-collision early warning display screen, audible and visual alarm lamp can stop early warning, while anti-collision early warning display screen does not show rear
The distance between the speed and front vehicle of vehicle and highway maintenance vehicle numerical value；If the driver of front vehicle does not subtract
Speed operation so that when front vehicle is more and more closer apart from highway maintenance vehicle, during the signal monitored is sent to by millimetre-wave radar
Heart processor, center processor is adjusted the distance and speed is calculated, and to audible and visual alarm lamp sends out strong light, the early warning of forte refers to
It enabling, the glow frequency of audible and visual alarm lamp improves, sound decibel increases, to warn front vehicle to carry out deceleration or lane change operation,
To keep safety traffic state.
Preferably, the anti-collision early warning display screen is LCD screen.
Preferably, the audible and visual alarm lamp is mounted on the top of the tail of the body of highway maintenance vehicle, and audible and visual alarm lamp position
In the top of anti-collision early warning display screen.
The advantage of the invention is that：The present invention uses millimeter wave detection technology, and rear car is calculated by signal processor
Speed and distance timely and effectively remind front vehicle to subtract by anti-collision early warning display screen and the dual alarm mode of acousto-optic warning light
Speed or lane change, meanwhile, it can also remind the driver of this vehicle to pay attention to the arrival of front vehicle, after this double shield can substantially reduce
The rear-end collision probability of square vehicle and highway maintenance vehicle increases front vehicle and care the car property and the safety of personnel.
