High-speed dynamic weighing system is widely used in the section that the overloaded vehicles such as highway, national highway and provincial highway are concentrated, and plays an important role in traffic administration, containment overrun and overload, protection road and bridge etc.At present, limitting by its application conditions, high-speed weighing system General Requirements construction volume is little, non-maintaining.Based on above feature, the strip sensor of high-speed weighing sensor many employings small volume, as fillet, quartz, piezoelectric film, etc.

High-speed weighing system is applied on the road of free flow row more.Compared with traditional charge station, the single lane width under freestream conditions cannot be fixed, and road conditions vary.And due to the length of sensor itself be in general fixing, so under the condition of different lane widths, traditional sensor vertical is difficult to accomplish the zero lap of sensor in the mode that garage direction is installed, full track covers, thus have impact on the weighing precision of high-speed weighing system, and significantly limit the promotion and application of strip sensor in high-speed weighing system.

Utility model content

The utility model provides a kind of vehicle high-speed dynamic weighing system of self-adaptation lane width, and described system comprises:

LOAD CELLS: alleged by described LOAD CELLS and track center line, angle is θ, by the quantity of controls θ value and bicycle road sensor, can meet the installation requirement of bicycle road zero lap, full covering;

Magnetic test coil: described magnetic test coil lays respectively at LOAD CELLS front, front end and LOAD CELLS rear, rear end, and front end coil provides vehicle snapshot signal, rear end coil provides vehicle ending signal;

Data acquisition controller: described data acquisition controller is for the treatment of the load cell signal collected and coil signal.

The vehicle high-speed dynamic weighing system of described self-adaptation lane width, is characterized in that, described angle θ:

0<θ≤90。

The vehicle high-speed dynamic weighing system of described self-adaptation lane width, is characterized in that, described LOAD CELLS, and the quantity that the side of the center line in each track is placed is n; As n>1, be parallel to each other at the sensor of the center line side in each track, and the distance between sensor is d.

The vehicle high-speed dynamic weighing system of described self-adaptation lane width, is characterized in that, the quantity of described LOAD CELLS:

1≤n≤6。

The vehicle high-speed dynamic weighing system of described self-adaptation lane width, is characterized in that, the distance between described LOAD CELLS:

200mm≤d≤10000mm。

Its concrete technical scheme is as follows:

Get n=2, d=1000mm, namely on a track, lay four LOAD CELLS 102, track is 1 meter along the distance between garage's direction upper sensor, and sensor becomes angle theta with track center line.If width of roadway equals the length sum of two LOAD CELLS, get θ=90 °, now the length direction of four LOAD CELLS is perpendicular to garage direction; If width of roadway is not equal to the length sum of two sensors, the quantity of control θ value and bicycle road sensor can be passed through, meet bicycle road zero lap, the full installation requirement covered.

Concrete, single lane width is N, and sensor length is L, then the computing formula of above-mentioned angle theta is:

$\mathrm{\&theta;}=\arcsin \left(\frac{N}{\mathrm{kL}}\right),k=\mathrm{ceil}\left(\frac{N}{L}\right),$

Wherein, N represents lane width; K is expressed as and realizes the full requirement covered, when θ determines, and the minimum sensor number required for bicycle road; Ceil represents and rounds up, such as, and ceil (2.1)=3.

Concrete, the vehicle high-speed dynamic weighing system of a kind of self-adaptation lane width that the utility model provides also comprises: two magnetic test coils, lay respectively at LOAD CELLS front, front end and LOAD CELLS rear, rear end, front end coil 101 provides vehicle snapshot signal, rear end coil 103 provides vehicle ending signal, a set of data acquisition controller equipment 104, for the treatment of the load cell signal collected and coil signal.

The beneficial effects of the utility model are: the vehicle high-speed dynamic weighing system providing a kind of self-adaptation lane width, the layout of LOAD CELLS on road surface is changed into arrange with the garage angled θ in direction layout by the layout perpendicular to garage direction that tradition is single, thus achieve the strip sensor zero lap of high-speed weighing system, the full installation requirement covered, enhance the adaptability of this type of high-speed weighing system, what improve high-speed weighing system goes out car accuracy rate and weighing precision.
