Abstract
The invention discloses a kind of automobile stabilization system based on LFMCW millimeter waves, including transmitting antenna, signal source, modulated signal, controlling alarm, signal processor, A/D is changed, demodulator, amplifilter, frequency mixer and reception antenna, millimeter-wave signal is launched by millimeter-wave automotive anti-collision radar forwards in real time, and the signal reflected with this front side target carriage is compared, processed by the difference frequency signal to two kinds of signals, can obtain the speed and distance of preceding object thing, and then contrasted the speed and distance with distance with the speed of safety, sound and light alarm is carried out if more than the safety margins reminds driver to slow down in time, if driver does not react in time, then system automatic retarding is until brake.
Description
Technical field
The present invention relates to a kind of automobile stabilization system based on LFMCW millimeter waves.
Background technology
In recent years, automobile has changed into the trip instrument being most widely used during we live, with extensively should for automobile
With the trip of people is more facilitated, but thing followed traffic accident is also increasing.How the generation of accident is avoided just into one
Individual problem demanding prompt solution.May work as weather conditions it is good when people's situation about being more likely to by being visually observed sentenced
It is disconnected, but when under atrocious weather situation, when eyes accurately cannot obtain information, the necessity of aid is just displayed
. is can not in time in the case of acquisition information particularly when there are other vehicles in front, it is more likely that will collide.
Increasingly tend to intelligentized society at this, intelligent transportation has also been put on schedule.Automobile collision preventing of the invention
System is significant for realizing intelligent transportation system, and the generation to preventing traffic accident also has positive role.Automobile is prevented
System is hit, the workload of driver can be not only reduced.In the near future, CAS is bound to turn into matching somebody with somebody for automobile indispensability
Put, Anticollision Radar also can be commonly used in automobile industry.
The content of the invention
It is an object of the invention to provide a kind of automobile stabilization system based on LFMCW millimeter waves, to solve prior art
In caused above-mentioned multinomial defect.
The present invention uses following technical scheme：
To reach above-mentioned purpose, the present invention provides a kind of automobile stabilization system based on LFMCW millimeter waves, including transmitting antenna,
Signal source, modulated signal, controlling alarm, signal processor, A/D conversions, demodulator, amplifilter, frequency mixer and reception day
Line, launches millimeter-wave signal, and be reflected back with this front side target carriage forwards in real time by millimeter-wave automotive anti-collision radar
Come signal be compared, processed by the difference frequency signal to two kinds of signals, can obtain preceding object thing speed and away from
From, and then the speed and distance are contrasted with the speed of safety with distance, carry out acousto-optic report if more than the safety margins
Alert to remind driver to slow down in time, if driver does not react in time, system automatic retarding is until brake.
Beneficial effects of the present invention：
There is provided a kind of automobile stabilization system based on LFMCW millimeter waves, by millimeter-wave automotive anti-collision radar in real time forward
Side launches millimeter-wave signal, and the signal reflected with this front side target carriage is compared, by two kinds of differences of signal
Frequency signal is processed, and can obtain the speed and distance of preceding object thing, so by the speed of the speed and distance and safety with
Distance is contrasted, and sound and light alarm is carried out if more than the safety margins and reminds driver to slow down in time, if driver is without anti-in time
Should, then system automatic retarding is until brake.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Specific embodiment of the invention is described below.
As shown in figure 1, a kind of automobile stabilization system based on LFMCW millimeter waves, including transmitting antenna 1, signal source 2, tune
Signal processed 3, controlling alarm 4, the conversion 6, demodulator 7 of signal processor 5, A/D, amplifilter 8, frequency mixer 9 and reception antenna
10, millimeter-wave signal is launched by millimeter-wave automotive anti-collision radar forwards in real time, and be reflected back with this front side target carriage
Come signal be compared, processed by the difference frequency signal to two kinds of signals, can obtain preceding object thing speed and away from
From, and then the speed and distance are contrasted with the speed of safety with distance, carry out acousto-optic report if more than the safety margins
Alert to remind driver to slow down in time, if driver does not react in time, system automatic retarding is until brake.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept is subject to equivalent or change, should all be included within the scope of the present invention.
