Road builds and transformation, completes the basic of country and each place traffic intelligent management system layout and engineering economic analysis, and obtains
More accurate, comprehensive volume of traffic collection information is the premise and important reference for describing traffic flow character.
Existing telecommunication flow information monitoring technology mainly uses the rack-mounted double excitation probe mode of portal frame, there is detected value mistake
Differ from big, poor real, increased to the pressure of rear portion data analysis, it is difficult to dynamic monitoring accuracy needs are met, for length
The observation of phase continuity, the data error of short-term gap observation or interim observation and error distribution are difficult to estimate, and are adopted in the presence of monitoring
The collection actual techniques problem that sub-population cost is high, cost pressure is big.
The content of the invention
Goal of the invention of the present utility model is to provide one kind can quickly, accurately complete telecommunication flow information Real-time Collection,
Meet dynamic monitoring purpose, and effectively reduce the traffic flow dynamic real-time acquisition system of monitoring collecting part cost.This practicality is new
The traffic flow dynamic real-time acquisition system technical scheme that type is provided, its main technical content is：A kind of traffic flow dynamic realtime is adopted
Collecting system, the present apparatus gathers portion, microwave sounding collection portion and total data treatment transport unit and constitutes by laser acquisition, laser therein
Detection collection portion is connected with laser signal processing unit by laser detector and constituted, and microwave sounding collection portion is by microwave detector
With microwave signal process unit composition, described laser detector and microwave detector set and are fixed in the vertical rod of highway side
Portion, laser detector is set each track of detection covering of the fan covering highway, the detection direction of microwave detector：It is in road level face
45~60 ° of angles and garage direction are in 30~45° angle.
Traffic flow dynamic real-time acquisition system technical scheme, realizes each information of road wagon flow auspicious disclosed in the utility model
The technical purpose that real, real-time detection is obtained, it is real-time that it is widely used in adjustment highway, city expressway, common road traffic flow
Monitoring collection, completes the real-time information collections, Various types of data such as vehicle whether there is, vehicle flowrate, speed, lane occupancy ratio and vehicle are sorted out
Bag is processed the equipment such as communication port, GPRS, Internet, the IC-card of transport unit by total data and uploaded again, is related management portion
Door is implemented offer reliability, the accurate data such as traffic administration, data statistics, information issue and is supported；Wherein laser acquisition and microwave
The combination of detection, can set up mounting structure using simple one side single pole, can not only complete each track on intensive collection highway
Each specific data value of vehicle, be easy to type of vehicle sort out treatment operation treatment, and overall cost cost be significantly less than it is existing
Traffic monitoring device.
Brief description of the drawings
Fig. 1 is the utility model pie graph.
Laser detector Real-time Collection line drawing after Fig. 2 and Fig. 3 are respectively road surface and road surface is got on the bus.
Specific embodiment
The traffic flow dynamic real-time acquisition system that the utility model is provided, this dynamic realtime acquisition system is adopted by laser acquisition
Collection portion, microwave sounding collection portion and total data treatment delivery unit composition.Laser acquisition collection portion therein is by laser detector
Be connected composition with laser signal processing unit, and microwave sounding collection portion is by microwave detector and microwave signal process unit group
Into.As shown in figure 1, laser detector 1 and microwave detector 2 are fixedly installed in the vertical rod 3 of monitored highway side, both
Antenna height is 6~6.5 meters, the monitored each track of highway of detection covering of the fan covering of laser detector therein 1, and its segment angle is not
More than 180 °, laser detector 1 often rotates a circle by detecting during covering of the fan by the speed of setting, according to determination collection essence
The angular interval for spending to set gathers density, is such as set to 0.5 ° of stepped intervals collection density, obtains in sector and sweeps away collection
To highway and highway on motor vehicle each point distance, adopted according to the data of laser detector by back-connected information processing part
Collection information, sets up garage's cross-sectional profiles coordinate in road surface space, is, perpendicular to cross-sectional profiles coordinate Z axis, to build with time shaft
The contoured three-dimensional space diagram of vertical road vehicles operation, as shown in Figures 2 and 3, according to three-D profile information, obtains road vehicles
Existence information, compares with all types of vehicle characteristic values, judges that vehicle is sorted out, and according to the overall height threshold value of setting, excludes the interference signal,
Accurate information is completed in real time to add up or count.The search angle of the setting of microwave detector 2 is with road level face in 45~60 ° of folders
Angle and garage direction are in 30~45 ° of angles, microwave sounding interarea is covered each track of highway, and border circular areas as shown in Figure 1 are
Main detecting area, each vehicle echo-signal that detection is covered in by track is entered by each vehicle by signal processing analysis and visited
Survey the area of coverage and obtain each vehicle real-time speed v successively, when the vehicle collected with reference to laser detector 1 carrys out the car time and left with car
Between time difference Δ t, obtain Vehicle length information, be combined with three-D profile information, efficiently obtain more accurate and reliable
Type of vehicle is sorted out.Follow-up data processing transmission unit can extract the telecommunication flow information in some cycles time, and program is whole
Reason, classification, statistics, transmission are including lane occupancy ratio, with user's information needed such as car percentages.
