Accompanying drawing explanation
Can understanding feature and advantage of the present utility model clearly by reference to accompanying drawing, accompanying drawing is schematic and should not be construed as and carry out any restriction to the utility model, in the accompanying drawings:
Fig. 1 shows the structural representation of the road speed system for prompting of embodiment of the present utility model.
Fig. 2 shows the structural representation of the signal detecting device of embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
In an embodiment of the present utility model, provide a kind of road speed caution system.
Fig. 1 shows the structural representation of the road speed caution system of embodiment of the present utility model.
With reference to Fig. 1, the road speed caution system of the present embodiment, specifically comprises sender unit 10 and signal detecting device 20.
In the present embodiment, sender unit 10 is arranged on position road needing Reduced Speed Now, signal detecting device 20 is arranged on vehicle, when vehicle arrives the distance preset with sender unit 10, signal detecting device 20 on vehicle processes this signal and carries out corresponding deceleration-operation to vehicle after detecting the signal of sender unit 10 transmitting.
In the above-described embodiments, as shown in Figure 2, signal detecting device 20 comprises signal receiver 21, signal processor 22 and annunciator 23;
Wherein, after signal receiver 21 receives the signal of the transmitting of sender unit 10, be transferred to signal processor 22 and process, then result is sent to annunciator 23, annunciator 23 is warned according to result.
Further, signal processor 22 carries out process detailed process to the signal received is:
According to the relative velocity that the relative distance between the calculated signals vehicle received and sender unit 10 and vehicle travel, calculate the time of vehicle arrival required for safety distance, and this time is sent to annunciator 23;
In the above-described embodiments, safety distance is the minor increment between the default vehicle vehicle that needs to reduce speed now to signal receiving device, namely need to start to slow down when vehicle arrives safety distance time, otherwise when the position that vehicle is slowed down by needs, the object of deceleration can not be reached.
Further, alert receipt after this, reminds vehicle to carry out the initial time of slowing down by the mode of voice to described.Or, after annunciator 23 receives this time, after this time period, reminding vehicle to reduce speed now by prompt tone.
In a further embodiment, signal detecting device 20 also comprises actuating unit, this actuating unit is connected with signal processor 21, the time in of being less than safety distance, starts the safety device on vehicle for the relative distance between the vehicle that signal processor 21 calculates and sender unit 10.
In the above-described embodiments, the signal that sender unit is launched can be radar signal, but is not limited to radar signal, and the signal of other types can realize the object of signal of the present utility model transmitting and receiving equally.
In the present embodiment, when sender unit launches radar signal, signal detecting device can use full range velocity radar device, this radar installation can receive whole frequency range, as X frequency, K (being commonly called as tripod), Ku frequency, new K frequency, Ka frequency, LASER laser, Ka-Laser, P frequency etc. frequently.This kind of velocity radar annunciator equipment is all effective in China, high speed is reacted sensitive especially, general 500 meters to 2 kilometers just forecasts in advance.
GPS radar detector principle: radar speedometer is the kinematic velocity drawing testee according to the calculating of backward wave frequency shift amount received.Radar beam shadow surface is large, and therefore radar velocity measurement is easy to captured target, need not fine sight.Radar equipment not only can be fixed on road surface, also can be arranged on scout vehicle, and the realization of on the go detects the speed of a motor vehicle, is " floating electronic police " very important component part; Secondly, the error of radar velocity measurement is approximately: vehicle velocity V increase and decrease 0.1031%V, can meet the requirement investigated and prosecuted traffic violation completely; Radar velocity measurement is adopted also to have the history of more than 20 year in the world, and technology maturation, with low cost.Situation before existing is opened, and on Beijing's urban pavement or to test the speed dorsad, but the radar speedometer also having had a small amount of forward to test the speed occurs.In the majority with forward speed measuring device on express highway.Be exactly that radar wave is consistent with automobile direct of travel with camera direction dorsad, the rear car plate of pick up camera shooting vehicle during overspeed of vehicle.Forward is exactly that radar wave and camera direction are contrary with automobile direct of travel, the front car plate of pick up camera shooting vehicle during overspeed of vehicle.
Based on above-mentioned, when vehicle being provided with radar detector, after receiving radar signal, report to the police, prompting car owner slow down at once.
In addition, judge whether to need to carry out Reduced Speed Now for the ease of chaufeur, sender unit can also be provided with image acquisition device, for gathering the graphicinformation of the position needing Reduced Speed Now, and being sent to signal detecting device, this setup can make when this position does not have pedestrian to travel, and the amplitude that vehicle can not carry out Reduced Speed Now or deceleration reduces, thus improve vehicle running efficiency, reduce the congestion in road because Reduced Speed Now causes.
Based on above-mentioned setting, the signal detecting device on vehicle is also provided with telltale, receives graphicinformation for display.
In addition, the telltale of the application can the read out instrument of public existing navigationsystem, thus can thin device, reduces costs.
In addition, pre-loaded setting the brief introduction of the unit of sender unit and stream of people's situation in this section can also be changed in sender unit of the present utility model, and need the reason of deceleration, and need the content such as main time section of slowing down, and when vehicle drives in range of receiving, by telltale, foregoing is shown, thus driver can be facilitated can to understand the road conditions in this section by fast speed, improve driving efficiency, ensure that arteries of communication is smooth and easy.
Road speed caution system of the present utility model, by the position signalization feedway slowed down at needs, vehicle arranges receiving device, vehicle drive to range signal feedway preset position time, the signal that sender unit is launched can be received, and the section needing to slow down is had by the signal determination vehicle front received, thus Reduced Speed Now can be carried out in time, the application's system can substitute the setting of the deceleration strip on existing road, thus vehicle can be reduced by by the problem brought during deceleration strip and improve crew comfort, reduce tire infringement.
In addition, needing the section of slowing down to arrange system described in the utility model, the loss of vehicle can not only can be reduced, and can noise be reduced, improve the traveling comfort of driver and conductor, simultaneously, do not need, by traditional deceleration strip, the loss of goods can be reduced, and distributing of dust can be reduced.
In addition, suggestion content can combine with the promotional content of setting unit by the application, forms personalized voice, image prompt system.
Although describe embodiment of the present utility model by reference to the accompanying drawings, but those skilled in the art can make various modifications and variations when not departing from spirit and scope of the present utility model, such amendment and modification all fall into by within claims limited range.
