Description
Technical field：
The invention belongs to the especial operation field of microwave communication, and in particular to the electromagnetic wave of high-frequency emission, electric field
The distribution of intensity, with distance increase successively decrease, with modulation various unlike signal carrier waves after straight line transmitting reason
By., by each vehicle-carried microwave reception system (Fig. 3), unlike signal intensity classification is pressed after reception on the way, converted
Into my car and microwave transmission system (Fig. 2) distance and find out the application of the various situations that front occurs in advance.
Background technology：
When the automobile for running on highway in the world at present runs into following four kinds of situations, due to notifying immediately
All cars are early prepared in section, therefore it is very high that the probability of disaster occurs.
First, when there is traffic accident or on the way break down parking when, be nowadays all to continue to use at the beginning of last century just
Using " tripod " be placed at about 50 meters and warn, remind car to note, due to being currently public at a high speed
Road road speed quickly, is waited when carrying out car and seeing " tripod ", and reaction is had little time, in addition in night and energy
In the case of degree of opinion difference, there is a chain of possibility for knocking into the back high.By display screen warn that be a period of time with
Thing afterwards, in addition under poor visibility conditions.
2nd, repair the roads on highway when needing lane change, having provisional barrier, have climb and fall and a hairpin curve nowadays all
It is to be warned with guideboard or display screen, but back car especially can not all be seen under disaster weather condition, therefore not
Know that the situation and distance of front generation are also how far, so as to early preparation is made, thus result in accident and occur again and again.
3rd, on the way, the calamitous weather blurred vision such as dense fog is met, when car is in mist " walk, touch front truck,
Do not walk, touched by rear car ", the relation in the urgent need to knowing the nearby automobile of operation and my car distance.Although at present
In the world special superior automobile is also equipped with trailer-mounted radar, but radar needs sizable pulse power, just can have
Effect reflection, so cost is high, and everybody is also interfered with same frequency.Also useful " laser "
Or " ultrasonic wave " range finding, but measurement distance is too short, and " laser " is kept off in calamitous weather
Do not work, easily cause bumper car accident.
4th, there is burst " group's mist " " sandstorm " " burning stalk " because current all highways can not all find out front
Cause not see the calamitous weather condition in front, also all can not and alarm, these information can not be transmitted
To system-wide section, allow the situation in front as you know, so, later automobile due to speed it is fast, can blindly rush
Enter distressed areas such as " group's mists ", cause serious traffic accident.Although foreign countries have also been invented " refractometry " spy
Mist equipment, can detect dense fog, but this equipment, and one, it is impossible to detect other calamitous weather, two,
The result of detection can not be immediately transmitted to all cars on highway, so disaster still occurs.
The task of the present invention：
Due to the above-mentioned four kinds situations that disaster easily occurs, solve without effective way for a long time, so existing every year
All constantly there is serious traffic accident in the whole nation, the whole world.
According to TV station and newspapers, there are several chains of rings to knock into the back the serious friendship of more than 100 car in the world every year
Interpreter thus occur, the especially Nanjing morning newspaper of on July 28th, 2014 report Ningbo-Hangzhou at a high speed eastern Mount Lushan section, due to
Climb and fall can all occur every year the traffic accident of two, 30 personnel's casualties, although lay at present intensive
Shake line to reduce speed, but jolting for automobile is well imagined, is informed if we shift to an earlier date two kilometers
The situation in front, and constantly remind and just have more preferable effect, these examples explanations will solve these difficult problems
Urgency, this task namely of the invention.
The content of the invention：
First, the purpose of invention：Exactly solved using the property of microwave communication above-mentioned four on highway
Hang-up, the safe driving allowed on highway actually changes reality, and this unnecessary injures and deaths is reduced or avoided
And property loss.
2nd, concrete technical scheme：It is that on a highway per car is all installed using the property of microwave communication
Microwave transmission system (Fig. 2) and microwave receiving system (Fig. 3), the frequency for using in the range of microwave section,
In the microwave transmission system (Fig. 2) that calamitously, should be furnished with dedicated channel (the unified channel in the whole nation), drive
On the way or when calamitously a situation arises need to open standby, such as meet and state four kinds of situations and can allow vehicle danger
For the name for ancient tribes in the east.
When the 1st, meeting generation traffic accident or scram, vehicle-carried microwave emission system (Fig. 2) now replaces
" tripod " launches electromagnetic wave into two kilometers and makees long-distance alarm with dedicated channel in place where the accident occurred, sends out
The microwave signal intensity penetrated and the different inversely proportional distribution according to the distance on this section, as " micro-
Ripple communicates the general arrangement on road " (Fig. 1), the distance of warning is expanded to 2000 meters from 50 meters, this
When all vehicles later on the co-channel microwave receiving system (Fig. 3) opened, i.e., receive by force by different sections of highway
Weak different signal, the AGC ports on microwave receiver (4), the different DC voltage of output size,
Jing dc amplifiers (6) amplify, then are sent to comparator (11) A.B.C.D.E and carry out respectively by different voltages
Relatively, dc amplifier (6) is met, now the corresponding delivery outlet of the comparator (11) of output voltage, i.e., defeated
Go out positive voltage, then trigger input (K) port of corresponding sound circuit (7), make sound circuit (7) thing
The sentence pronunciation of respective distance " rice " number is first recorded, while in the corresponding output port of comparator (11)
And the luminous tube for connecing, it is also simultaneously luminous, the eye of such driver, ear, can perceive simultaneously and front thing
Therefore the distance of spot.Simultaneously Microwave emission side, also records the sound circuit (3) for recording accident details,
Taken out by related K buttons, it is now co-channel micro- with carrier being frequency modulated mode modulated microwave emitter (1)
Wave receiver (4) can allow driver more to know that front accident is detailed by frequency discrimination voice restoration, loop play
Feelings, allow well all automobiles on the way early to know the situation of front generation and the distance at once of place where the accident occurred and my car,
Early do Emergency Preparedness, it is to avoid accident occurs.
2nd, meet to be repaired the roads on highway and need lane change, there are temporary obstructions, when having upper and lower abrupt slope and bend, there are us
This set microwave transmission system (Fig. 2) and microwave receiving system (Fig. 3), highway administration side can be on these roads
Section puts this set microwave transmission system (Fig. 2) from the unified dedicated channel in the whole nation, and installed in these calamity is easily sent out
Evil section.There is the record with the sound circuit (3) of local circumstance same sentence with record on 1 method carrier being frequency modulated
Sound, circular modulating microwave transmitter (1), to the two kilometers of section transmittings of road direction to the car.By this section

(1) all must be identical on all cars with the channel of microwave receiver (4).According to 1 measurement of adjusting the distance
With the player method of voice transfer, it is possible to immediately know that current, forward and backward side's vehicle and my car distance and
Type of vehicle, accomplishes to know what's what, and is ready at all times to prevent collision.
4th, such as " group's mist ", " sandstorm ", " burning stalk " the disaster weather of happening suddenly, automobile blind is being prevented at present
Mesh pours " group's mist " area, and also without prevention device, therefore it is high that the possibility of accident occurs.We design
Match with this set microwave transmission system (Fig. 2) and microwave receiving system (Fig. 3), can detect in time
" group's mist ", " sandstorm ", the sensor (number of patent application is 2012.10465988.X) of " burning stalk ",
Highway administration can install this sensor, capture burst in the multiple location of disaster, every 1 kilometer of road
" group's mist ".And with putting the microwave transmission system (Fig. 2) of our this set dedicated channel, then mix record and have disaster
The sound circuit (3) of type and intensity, is also equipped with the acceptance of this channel, with 1, therefore can be from sending
By the broadcasting and the warning of light of voice in signal, know at the how many distances in front, there is which kind of disaster,
Unlikely blindness pours blurred vision area, brings about great losses.
5th, advance in blurred vision area, such as find that microwave receiving system (Fig. 3) is informed, with adjacent car apart from mistake
When near, to prevent collision, we draw positive voltage in the luminous tube interface of comparator (11) A, right
Emergency alarm device (14) is connected, reminds the moment to note.
6th, it is traveling on highway, often there is the situation of front vehicles sudden deceleration or brake, if now can not
Find out in time, will blindly break through, it is dangerous very big, there is no this kind of find out prevention device at present.We
Vehicle-mounted " two cars distance is urgent to shorten warning circuit " is devised for this (Fig. 5).When front automobile sudden deceleration or
During parking, what our microwave receiver (4) was received is separated by the dc amplifier (6) obtained respectively when 2 seconds
Output voltage, will constantly raise.If because two car constant speed, the voltage for measuring just should be equal.If I
