The vehicle speed prewarning module includes radio receiver and variable display means, electric supply installation, is arranged on away from intersection
At certain length before mouth import track section, for the result of receive information processing module and the corresponding prompting of display
Information
The wireless transmitter module, fixed video detector and radar sensor are connected with message handler respectively, described
Message handler will be sent to wireless transmitter module to data processed result, and wireless receiving module receives data processed result, so
Pass through variable display module real-time display afterwards.
In the present embodiment, the fixed video detector uses ccd video camera, is specifically intelligently handed over using LSC-C500Tpro
Logical video camera, 4.4 μm of 4.4 μ m of Pixel Dimensions, pixel 5,000,000, possesses 20 Zoom Lens, can automatically switch it is wide dynamically with can
Noise reduction is obtained in the use environment of insufficient light, supports the image of full HD quality to export, at output digit signals and information
Manage device connection.
The radar sensor can measure vehicle real-time speed, and its application principle is Doppler effect, when radar is sent out
When the high-frequency signal penetrated is radiated at the mobile target reflection in its sphere of action, its frequency values change, and using transmission and receive
The difference on the frequency of signal, the speed of object of which movement is calculated by formula, and this Doppler frequency shift is proportional to the speed of mobile target.
From the HT3000 velocity radars of Hangzhou Lai Lai Science and Technology Ltd.s production, the radar sensor degree of accuracy of testing the speed is ± 1km/h,

Embodiment two
As shown in figure 3, a kind of crossing inlet track vehicle guiding signal control method, comprises the following steps：
S1, amber light open it is bright before, determined by fixed video detection instrument and the real-time collection vehicle information of radar sensor
The position of vehicle and speed, and the information of vehicles is transmitted to message processing module；
S2, described information processing module are handled information of vehicles, judge that whether vehicle is in friendship when amber light opens bright
In the section of prong import track；
S3, if so, then enable signal control module, the signal control module green light will at the end of proper extension it is green
The lamp time makes vehicle during green light by stop line, and intersection, while variable display means are sailed out of before amber light terminates
Show the green printed words of " please pass through "；If it is not, then variable display means show the red printed words of " please slow down ", vehicle deceleration is guided
And stopped before stop line.
Specifically, the vehicle safety in crossing inlet track section is that certain vehicle can open in red light by distance
Maximum distance (it is assumed that import track vehicle does not allow acceleration to drive into intersection) when passing through stop line before bright between stop line
For：
x1=v0ty-a-b
In formula：v0--- the car speed (m/s) when steady yellow opens bright；
ty--- steady yellow duration (s)；
A --- signalized intersections width (m)；
B --- Vehicle length (m).
Specifically, the length in crossing inlet track section is that certain vehicle can be before stop line during emergency
The minimum distance of (braking acceleration is less than vehicle maximum braking acceleration) between stop line is：
x2=v0δ+v0 2/2amax
In formula：v0--- the car speed (m/s) when steady yellow opens bright；
δ --- time of driver's reaction (s)；
amax--- vehicle maximum braking acceleration (m/s2)。
Suitable for x2More than x1Situation, even the distance between vehicle and stop line be less than x2More than x1, then vehicle can not
Stopped by braking before stop line, be also unable to maintain that former speed passes through stop line.
Variable display means position in the vehicle speed prewarning module is located at x before the original position of crossing inlet track3Place：
x3=v1·δ；
In formula：v1--- speed (m/s) of the vehicle in detection；
δ --- time of driver's reaction (s).
The green extension of the signal control module is：
If there are several cars to be in the section of crossing inlet track simultaneously, each vehicle is needed
Green extension maximum is as actual green extension, i.e.,：
Δ t=max (Δ t1,Δt2,…Δtk),
In formula：v1--- speed (m/s) of the vehicle in detection；
--- signalized intersections width (m)；
S --- the distance (m) away from stop line；
ty--- steady yellow duration (s).
Above-described embodiment combines actively prevention and passive protection, constructs a kind of based on guiding and crossing inlet car in advance
In road protect system, the vehicle to crossing inlet track area will be entered, by speed guide system, allow driver can and
When, it is accurate, resolutely take appropriate decision-making, inform that driver should accelerate by intersection or ramp to stop；Hand over coming into
The vehicle in prong import track section, by green light delayed time system, makes vehicle safety pass through intersection.Can be with by this method
Driver's driving comfort is improved, impatience is reduced, reduces due to driver in crossing inlet track due to sentencing to signal lamp
Break and go up the presence slipped up and the traffic accident number occurred.
Above-described embodiment is the preferable embodiment of the utility model, but embodiment of the present utility model is not by described
The limitation of embodiment, it is other it is any without departing from Spirit Essence of the present utility model with made under principle change, modify, replace
Generation, combination, simplify, should be equivalent substitute mode, be included within the scope of protection of the utility model.
