Abstract
The invention relates to radar traffic pre-warning phonetic cueing device. Emission radar is set on the ground. The relevant radar phonetic pre-warning cueing signal can be broadcasted by the carried radar receiver for the driver at traffic crossing, hazardous location etc by radar antenna short distance phonetic wireless transmission technique which is more convenient, exact, and safer compared with the figure and words type information gained from the GPS carried radar screen display.
Description
Technical field:
A kind of invention about radar particularly relates to a kind of prewarning speech prompting radar that is used for traffic safety.
Background technology:
Wave number concentrates on the above bold and unconstrained metric wave of 60GHz, and the wavelength of this wave band is shorter, and antenna beam is narrow, because frequency is higher, Doppler's wave band of speed of detection is accurate, and the radar system volume is little, can allow the littler of wireless and miscellaneous equipment design, installs onboard easily
[1]Millimeter wave 50GHz wave band antenna radio station can provide the radio of short distance colour TV signal, datafax and voice to transmit, it can transmit the digital signal of 6.3Mbps speed, or analog image and voice signal, system can cover 10km or longer transmission range under good atmospheric condition, consider the decay of rainwater weather, use transmission range to be 1-3km
[2]
The automobile of our country increases sharply with millions of speed every year, and road construction does not catch up with demand, and also corresponding unprecedented soaring because of the traffic casualties, country needs more effective traffic insurance technology and occurs.Car radar also is to have the market potential competitive edge for the automaker, and traffic law department and public sector also require safer automobile, from automobile buyer and owner's angle, car radar is convenient and not expensive, very attractive as a safety feature.
The appearance of GPS trailer-mounted radar is the another achievement of science and technology under this overall background just, the essence of this steady arm is by forming the once continual location of round-the-clock per second signal according to 31 satellite groups in 20200 kilometers sky of earth surface, and user from all parts of the world finishes navigation into automobile by gps satellite navigator received signal.This steady arm can provide the needed hundreds of thousands bar of driver related city road, crossing, road, refuelling station, viaduct or the like relevant information, and the driver can know the position and the desired related data at own place at any time.But this information is to show with the mode of screen with figure and literal, and weak point is that the driver must see figure on the screen and literal just can be known with eyes and needs information.Especially in the way of running car, watch figure and textual matter on the screen to divert attention, very big potential safety hazard is also arranged.
Also has a kind of radar velocity measurement viameter that is used for traffic control, it also is detectable signal that microwave or millimeter wave sent and a return signal of utilizing radar, automatically snap the automobile that those furious drivings are made a dash across the red light, so both can realize the unattended of crossing and important highway section, and suppress the driver and drive in violation of rules and regulations.
More than the appearance of two kinds of radars be enough to illustrate that radar has played important effect in traffic safety, also show the maturation of Radar Technology simultaneously in this field.
Summary of the invention:
Can change into image and speech signal according to transmitting and receiving of above data radar microwave especially millimeter wave, and be directional transmissions and unidirectional acceptance, can miniaturization, the characteristics of high reliability.It is fully feasible inventing a kind of prewarning speech prompting radar installations that is used for highway traffic safety.To specific road conditions such as the traffic intersection in city, Dangerous Area, viaduct, highway, charge station, refuelling stations, give the driver in advance voice signal inform traffic information.This has for traffic safety and is of great importance.
Description of drawings:
Such as: " note that 200 meters, the place ahead are crossroads, please slow down and go slowly, note front vehicles, note traffic lights, turning left is so-and-so road, and turning right is so-and-so road." and for example: " and 150 meters, the place ahead be descending to left sharp turn, note dodging and safety." wait voice messaging inequality.
The emission radar of radar traffic prewarning speech prompting device is mounted on the ground of city intersection, hazardous location, viaduct, highway, charge station and refuelling station, the signal beam of emission radar is towards coming to automobile, come the trailer-mounted radar receiver in automobile to do one way signal reception and instant the broadcast, as shown in Figure 1, after in automobile drives into radar emission wave beam coverage, trailer-mounted radar receiver received speech signal.As shown in Figure 2, after automobile rolled enclosing of radar emission wave beam covering away from, the trailer-mounted radar receiver stopped to play voice signal, therefore the driver was had the fidgets.
The advantage of radar traffic prewarning suggestion device of the present invention is:
1, voice messaging is passed on more hommization, than faster, clearer and more definite with eyes picture with the aid of pictures and Word message, needn't be expert at Divert attention in the car way, particularly to the driver who is unfamiliar with road conditions more need, more convenient, therefore also safer.
2, each prewarning speech prompting can both make the driver cheer up, and obviously improves the driving safety coefficient.
3, radar traffic prewarning speech prompting device adopts millimeter-wave technology, can miniaturization, and signal is more accurate, and installs easily.
4, the trailer-mounted radar receiver receives only and plays voice signal, receive and do not make image and receive, so technical costs is low, reliability is very high and volume is little, cost is low, and the automobile owner is ready to accept.
5, can round-the-clock realization unmanned management.
Embodiment:
Its principal character is that the emission radar is installed on the ground, make the automobile of radar beam on direct of travel beyond the setpoint distance, certainly because the distance that the position difference of installing requires radar beam to cover is different, the voice messaging that each emission radar sets all is to deposit in when mounted according to the physical location of its installation and the concrete condition of environment, and the information of therefore launching radar emission is accurately.The physical location that the emission radar is installed is different with environment, and stored voice messaging is also different.
The trailer-mounted radar receiver of installing on the automobile.Radar receiver is play the voice messaging of relevant road at once automatically when automobile has sailed regional that the radar beam of emission radar covers into, for driver's further work is carried out mental preparation in advance.

Claims (2)
1. radar traffic prewarning speech prompting device comprises: the early radar warning speech prompting system of specific road section such as urban traffic intersection, Dangerous Area, viaduct, refuelling station, charge station.It is characterized in that at floor mounted emission radar antenna, transmission prewarning speech prompting information is installed the trailer-mounted radar receiver on automobile, the mode that receives and play is transmitted traffic information to the driver.
2. according to claim 1, radar traffic prewarning speech prompting device is characterized in that, surface launching radar in ground is that radar deposits relevant language message in when surface launching radar in ground is installed according to different location, position and environment in advance.
