Description

Vehicle automatic parting direction device

In transport by road, often to carry out charge to various vehicles, its expenses standard of different vehicles is different.What the utility model was related is a kind of device of discerning vehicle, and it can measure overall height, wheelbase and the axletree number of various vehicles automatically, and identifies concrete vehicle thus, for vehicle toll provides the foundation of charging accurately.

In the prior art, a kind of infrared of utilizing is arranged, receive and measure the device that array is discerned vehicle, described measurement array is divided into orthogonal array and two parts of horizontal array, described emission array and receiving array lay respectively at the both sides on road surface, when vehicle passes through, the tested part of vehicle will be blocked infrared ray, measure related data thus, existing its horizontal survey array of this vehicle recognition device is by 50-60 infrared, receiver is arranged equally spacedly and is formed, the about 10cm of its spacing always is about 500-600cm, when front and back wheel is blocked certain two bundle in the horizontal array respectively during infrared rays, to record wheelbase, when vehicle body (comprising headstock or compartment) blocks in the orthogonal array than a few bundle infrared ray of short that of vehicle body, to record overall height (comprising headstock height or compartment height), wheelbase and the overall height passing through at last to be surveyed are determined concrete vehicle.The deficiencies in the prior art part is:

One, 50-60 infrared of the palpus of along continuous straight runs arrangement in one line, receiver, this is non-remunerative economically.

Two, when the automobile band trailer and is entered measurement zone, when (during the band trailer, should can be regarded as two cars) or two automobiles that suffer very closely entered measurement zone simultaneously, existing apparatus can not be differentiated, treat it but they are used as an automobile, thereby bring loss to charge.

Three, measuring overall height all is to be benchmark with the headstock part, and existing apparatus can not be differentiated it with the compartment of headstock part and headstock back.This just might measure the height of the goods on compartment and the compartment by mistake as overall height, thereby brings error for the judgement of vehicle.

Four, the vehicle kind of existing apparatus identification is fewer, has only about the 20-1000 kind.

The purpose of this utility model is to overcome the deficiencies in the prior art and designs a kind of a large amount of infrared, receiver can saved, and can have the vehicle automatic parting direction device of higher discernment again.

The utility model is realized as follows: described vehicle automatic parting direction device, measuring array by infrared, reception forms, described measurement array is divided into horizontal array and two parts of orthogonal array, it is characterized in that: described horizontal array is made up of the infrared below 10, receiver, and its arrangement mode is a unequal-interval.Horizontal array is used for measuring vehicle front and back wheel wheelbase and axletree number.Described orthogonal array is divided into two groups up and down, and every group by 6-12 infrared, receiver composition, and last group arrangement mode is a unequal-interval and comparatively loose, and following group arrangement mode is equidistant and comparatively intensive.Last group is to be used for measuring overall height, and following group is the gap that is used for discerning between two cars; There is one to be specifically designed to infrared, the receiver that starts the high array of survey in the described horizontal array, in other words, have only when vehicle front blocks it, survey high array and just start working, this infrared, receiver and vertical survey array are 100-150cm apart.

The utility model has following advantage:

One, this device can be measured overall height, wheelbase and three data of axletree number simultaneously, by these three data, can discern the vehicle more than 3000 kinds, and its identification quantity substantially exceeds prior art.

Two, save a large amount of infrared, receiver, saved funds.

Three, can differentiate the vehicle number that enters measured zone exactly.Comprise distinguishing whether the vehicle that enters measurement zone has trailer, thus the loss when avoiding charging.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is this device user mode figure

Fig. 2 is that infrared, receiver are measured arrayed figure

Fig. 3 blocks the infrared beams synoptic diagram for wheel.

R1, R2 among the figure ... be infrared, receiver, the 1st, wheel, the 2nd, mudguard.

In Fig. 1, when automobile when driveway shown in the figure enters measurement zone, infrared beams will be blocked in measured position, at this moment the infrared remote receiver end can receive infrared ray, measures related data thus.

Shown in Figure 2 is a specific embodiment of this device, and the horizontal array of present embodiment is made up of 7 infrared, receiver R1-R7.Described R1-R7 distance overhead is 5-10cm.Wherein: the distance between R1 and R2, R4 and R5, R6 and the R7 is 2-20cm; Putting apart among point and the R4R5 among the R1R2 is 300-320cm; Putting apart among point and the R6R7 among the R1R2 is 490-510cm; In the orthogonal array up and down two groups each form by 6 infrared, receiver R8-R13 and R14-R19, its arrangement mode is to go up group to be unequal-interval and comparatively loose, following group is equidistant and comparatively intensive, wherein the distance on R13 and R14 and ground is 120-125cm, R8 and ground are about 220cm apart, R19 and ground are about 20cm apart, and the infrared in the described horizontal array, receiver R3 and orthogonal array are 100-150cm apart.

The concrete principle of work of present embodiment is summarized as follows:

The identification of axletree number N: because wheel 1 radially has certain width, have only it might block R1R2 (or R4R5 simultaneously, or R6R7) as shown in Figure 3, and the condiment of wheel back such as mudguard 2, because mudguard has only a very thin dot thickness, so it can not block R1R2 (or R4R5 or R6R7) still as shown in Figure 3 simultaneously, so when R1R2 or R4R5 or R6R7 are covered simultaneously, must be covered this moment by wheel, when entering measurement zone, an automobile covered continuously twice as if R1R2, illustrate that this car has two axletrees,, illustrate that this car has three axletrees if covered continuously three times.

The measurement of wheelbase L:

(1) block R1R2 when trailing wheel, front-wheel also end blocks R4R5, shows that wheelbase is less than 310cm;

(2) block R1R2 when trailing wheel, front-wheel blocks R4R5, shows that wheelbase is 310cm;

(3) block R1R2 when trailing wheel, front-wheel kept off R4R5 earlier but did not also block R6R7, show wheelbase greater than 310cm less than 500cm.

(4) block R1R2 when trailing wheel, front-wheel blocks R6R7 and shows that wheelbase is 500cm

(5) block R1R2 when trailing wheel, and front-wheel had kept off R6R7, showed that wheelbase is greater than 500cm.

The identification of overall height H: described overall height, refer to the height of headstock part, rather than the height of goods on compartment, headstock back and the compartment, according to actual knowledge, determined that the most general value of a headstock length is about 100-150cm to a large amount of vehicles.The R3 in the horizontal array and the distance of orthogonal array are exactly to determine thus, have only current the wheel when blocking R3, the orthogonal array of identification overall height is just started working, write down the overall height data, when front-wheel kept off R3 earlier, and this moment the headstock back the compartment will block and survey high array, worked and finished but survey high array this moment, the height in compartment just can not go on record, thereby avoids mistake to survey.Survey in the high array by under the height on infrared, receiver R13 and ground, be according to the actual knowledge of a large amount of vehicles and definite, be about 125cm, like this when vehicle enters measurement zone, even the shortest headstock also can block R13 at least.When headstock only blocked R13, overall height was between R13, R12 height overhead; When headstock blocks R13, R12 simultaneously, overall height between the height on R12, R11 and ground, and the like.

The identification in the gap between the two cars: be in lower position owing to survey gap array R14-R19, so this array will all be blocked by car body when vehicle enters measurement zone.When vehicle body all passes through, receiver will receive by the road infrared ray next to surface launching, identify a gap, because being defined in, the adjacent spacing of R14-R19 is not more than in the dimension scope of drawbar between radially, so when the automobile that has trailer enters measurement zone, its drawbar must block some among the R14-R19, and being identified as thus is the automobile that has trailer.If instead be blocked without any one among the R14-R19, identifying thus is two automobiles inlet zone simultaneously.

Array is measured in described infrared, reception, with the received single-chip microcomputer of sending into for information about, automatically above-described overall height H is finished in control, axletree is counted the measurement of N, three parameters of wheelbase L by single-chip microcomputer, and judges its vehicle automatically, and the vehicle that this device can be known reaches more than 3000 kinds.
