Abstract
The utility model relates to an automatic detector for vehicles, which is used for measuring the chassis data of various running automotive vehicles, and the chassis data comprises the shaft number, the tyre number of each shaft, the tyre width, and the wheel track. The utility model is used for realizing the automatic classification for various transient vehicles. The device is characterized in that the chassis is provided with at least four sensors which form staggered arrangement; a power cord of each sensor is integrally connected in parallel to connected with a power supply; a sensor signal is connected with a microcomputer, and each sensor has a definite size. When the vehicle passes, the tyre number of each shaft, the tyre number, the width and the wheel base can be collected, and the road toll of the vehicle can be determined.
Description
The utility model relates to a kind of motor vehicles chassis-date of measuring in all kinds of the advancing, and comprises the number of axle, every arbor wheel tire number, and tyre width and wheelspan are realized the automatic classification to passing various vehicles.
At present, the toll of domestic vehicle is proportional with standard lifting capacity or row's seat number of vehicle, and is irrelevant with actual load-carrying or year member's situation of vehicle.For example, the standard load-carrying of liberating 141 type trucies is 5 tons, and the toll of this type car is 5 yuan, and therefore, no matter this type car is fully loaded or unloaded, its toll is 5 yuan, wants to realize automatic charge, must be able to discern the standard load-carrying of vehicle.
The automatic detection device that has now occurred mainly contains two classes:
One class is a vehicle License Plate Automatic Recognition System, this system by automatic identification vehicle license distinguishing different vehicles, but as this system of employing, at first license plate is clear, as contaminated, then system can not discern; Secondly nationwide license plate database must be set up, the licence plate and the type thereof of domestic existing all vehicles should be write down in this storehouse, otherwise, even identify licence plate, do not know which kind of vehicle this car is yet, finishing this, to be operated in current be unpractical.
What another kind of device adopted is the infrared scan technology, this system utilizes the whole track of infrared ray correlation switch scanning, when vehicle passes through, can obtain the image of vehicular sideview profile, by the identification of vehicular sideview profile being judged the vehicle of this car, owing to the vehicle that travels on the highway usually causes the side profile distortion because of reasons such as loadings, therefore brought huge difficulty to identification, therefore the discrimination of this system is unsatisfactory.
The purpose of this utility model is by axletree number, every tire number, tyre width and wheelspan are discerned a kind of car category automatic detection device that type of vehicle designs.
The utility model is made up of base and four pressure transducers at least, and pressure transducer is staggered front to back and is arranged on the base, and the power lead of each sensor is connected in parallel respectively and links to each other with power supply, and signal wire connects together respectively and links to each other with microcomputer.The length of each pressure transducer can be 10 centimetres, and its width is 1 centimetre, decides as requested.Said base available metal material or concrete material are made.
Realization of the present utility model has measures reliably, the nicety of grading height, and the anti-adverse environment ability is strong, advantages such as long service life.
Its principle of work can give to describe in detail with reference to the embodiment accompanying drawing.
Fig. 1 is a front elevation of the present utility model.
Fig. 2 is a side view of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Fig. 4 is the layout synoptic diagram of the utility model on the track.

Embodiment
At present, this device is at Yellow River Bridge, Jinan charge station installation in position.
By figure (2) as can be known, sensor (1) is arranged on the base (2) with being staggered, and the power lead of sensor (3), (4) connect together respectively and power supply joins.Output signal line (5) is linked to each other with computing machine (11) in the tollbooth (10) by communication line (9).
The utility model car category automatic detection device (7) is installed in the subsurface in the sealing track (6) of tollbooth (10) front, and vertical with the vehicle direction of passage, because this device when vehicle passes through, must trigger this device across whole track.The computing machine (11) that its signal is sent in the tollbooth (10) by communication line (9) is handled, and can discern various vehicle classification, thereby determines expenses standard.
Pressure transducer among the utility model embodiment wide 1 centimetre (width can change according to the requirement of accuracy of detection), long 10 centimetres, totally 300 (this number can be determined according to the requirement of accuracy of detection), each pressure transducer can carry the power of 10-500 kilogram, promptly be no more than 500 kilograms pressure at right angle more than 10 kilograms again, promptly exportable 9V voltage as long as it is applied.300 pressure transducers are equivalent to 3 meters long rules, and each pressure transducer promptly is a scale, and accuracy of detection is 1 centimetre.
After energized, each pressure transducer promptly enters readiness for operation, during as the wheel shaft by vehicle, its loading will apply pressure to pressure transducer by tire, output signal is sent to computing machine by coupling arrangement thereupon, according to the pressure transducer triggering situation, calculate the tire number on this wheel shaft, width and wheelspan, behind the process certain hour, sensor no longer is triggered, and thinks that then this car passes through, computing machine compares the data in detected data and the standard model data storehouse, can determine the toll of this car.
When the vehicle passing detection device, the wheel tire pressure is crossed (triggering) A sensor, and its tyre width is:
Tyre width=AX sensor width
Supposing has L sensor not to be triggered between tire and the tire, then wheelspan is:
Wheelspan=LX sensor width
During vehicle process pick-up unit, all will gather as above these data on each axle, after the time that all the sensors all is not triggered surpasses a set time.Think that promptly this car passes through, this detects end.
Claims (3)
- The car category automatic detection device that 1, can connect machine with microcomputer, it is characterized in that going up at least four of settings at base (2) is staggered front to back the pressure transducer of arranging (1), the power lead of each sensor (3), (4) are connected in parallel respectively and link to each other with power supply, and the signal wire of sensor (5) links to each other with microcomputer respectively.
- 2: according to the said car category automatic detection device of claim 1, it is characterized in that the length of said sensor (1) can be 10 centimetres, its width is 1 centimetre.
- 3: according to the said car category automatic detection device of claim 1, the said base of its feature (2) available metal material is made or is made with concrete material.
