Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can limit according to claim
Fixed and covering multitude of different ways is implemented.
A kind of traffic light control device precisely detected based on vehicle flowrate, as Figure 1-3, including traffic light apparatus 1, car
Statistic device 2 and car-mounted device 7.Traffic light apparatus 1 is arranged on the front at each crossing, and car statistics device 2 is arranged on
The centre in reverse track and with the wireless connection of traffic light apparatus 1.Car-mounted device 7 be arranged on each car on and with car statistics device
2 wireless connections.
Car-mounted device 7 is arranged to a control box, including shell body and internal circuit board, internal circuit board are provided with data
Acquisition interface and spilling is connected with the control device on automobile outside shell body.Car-mounted device 7 includes vehicle speed detector device, vehicle-mounted
Controller and GPS sending modules.Vehicle speed detector device is used for the speed of collection vehicle and the speed of detection is transmitted to vehicle-mounted control
Device, vehicle speed detector device are AD sampling modules, sampling interval 0.5s, and the data of collection are transmitted to vehicle-mounted control in real time
Device.Vehicle Controller receives the incoming speed of vehicle speed detector device and compared with default speed, when the speed ratio of detection
Default speed hour, Vehicle Controller control GPS sending modules start.Vehicle Controller is when starting installation by manually setting
The pre-set velocity of vehicle is put, is traditionally arranged to be 10km/h, therefore when Vehicle Controller receives the vehicle speed less than 10km/h,
Vehicle Controller just controls electric in GPS sending module automatic starts.GPS sending modules launch setting frequency range signal after opening supplies
Car statistics device 2 is detected.The signal of setting frequency range for during manufacture program setting with car statistics device 2
On detection frequency range it is corresponding, so as to more targetedly detect.
Car statistics device 2 is arranged to the housing of a sealing, and housing low side is provided with column, the height of column with it is vehicle-mounted
The vertical height that device 7 is arranged on car is identical.Car statistics device 2 is set on jube between track in the opposite direction or flower nursery
On, for detecting the vehicle on the right of crossing, the right is with respect to accompanying drawing and the right for saying, the direction setting carried out for convenience,
But the invention is not limited in the setting in these directions.Enclosure interior is provided with circuit board, and circuit board is connected with the power supply of outside
Power supply.Car statistics device 2 includes GPS receiver module, aspect sensor, car statistics controller and wireless sending module.GPS
The gps signal of the setting frequency range of the GPS sending modules transmitting for the car-mounted device 7 that receiving module detection enters in detection range, together
When obtain distance between car-mounted device 7 and car statistics device 2, GPS short distance positionings can cause error to narrow down to 0.05m,
The detailed process for obtaining distance is prior art, is no longer described in detail herein.Aspect sensor obtains car-mounted device 7 and horizontal line
Between angle, due to car-mounted device 7 and the same level of car statistics device 2 height, therefore aspect sensor can directly sense
Angle between car-mounted device 7 and horizontal line, therefore car-mounted device 7 is to the direction of motion lead of car so that with being filled from car statistics
2 horizontal line is put, forms a leg triangle.Car statistics controller is according to car-mounted device 7 and car statistics device 2
Between distance distance and the angle between car-mounted device 7 and horizontal line calculate track belonging to car-mounted device 7.As shown in figure 3, vehicle
The process that statistics controller calculates the track belonging to car-mounted device 7 is that car statistics controller obtains car-mounted device 7 and united with vehicle
The angle that distance between counter device 2 is a between car-mounted device 7 and horizontal line is β, so as to be calculated according to the cosine law of triangle
Distance=a/cos β between car statistics device 2 and track.Because there is certain width in track, therefore in installation car statistics dress
With regard to artificial inside car statistics device 2 and the distance input car statistics controller in each track when putting 2, due to differently
The lane width of the road in area is different, therefore car statistics device 2 and the distance range in each track are also different, distance
Range wide is the width in track.The distance between car statistics device 2 and track and the car statistics device 2 that originally set with
The distance range in each track is compared, and show that the distance between the car statistics device 2 measured and track is fallen into by contrast
In which track distance range, the car just belongs to the track, draws track belonging to car-mounted device 7, enters detection new in detection
The car statistics number in the track of the car-mounted device 7 of scope adds 1, obtains each lane flow amount.Wireless sending module is every
The vehicle flowrate in individual track is transmitted to traffic light apparatus 1, a general detection statistical result of 0.5 second hair.
Traffic light apparatus 1 includes wireless receiving module, traffic light controller and traffic LED signal lamp.Wireless receiving module
The information of vehicle flowrate in the incoming each track of car statistics device 2 is received, and the information of reception is transmitted to traffic light controller.Hand over
Logical lamp controller calculates the time of all directions traffic lights opening and closing, and control according to the information of vehicle flowrate on road of all directions
Signal processed is transmitted to traffic LED signal lamp.Traffic light controller calculates the process of the time of all directions traffic lights opening and closing
For, (track flow-average vehicle flow)+fiducial time green light opening time=time radix *, wherein time radix=2s/,
Fiducial time=60s.Such as the time of the straight trip green light unlatching in east-west direction, when the vehicle flowrate by eastern westerly direction is 30
When, and the average vehicle flow at crossing be 25 when, average vehicle flow refer to detecting all vehicle flowrates in crossing sum total divided by
Track direction number is detected at crossing, by east westerly the green light of direction running opening time for 2s/ * (30-25)+
60s=70s.Traffic LED signal lamp is lighted or closed according to traffic light controller control signal.So as to reach intelligence
Crossing traffic is controlled, is preferably prevented due to caused by traffic lights the problems such as traffic jam.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
