Abstract
The utility model relates to an automatic weigher for a vehicle running on a road surface. The automatic weigher comprises a weighing platform, a sensor and a controller. The sensor comprises a plurality of circular sensing surfaces. A plurality of groove bodies are uniformly formed on each sensing surface. A strain foil is arranged in each groove body. A signal circuit of each strain foil is connected with the controller. A circular surface support leg is arranged on and adapted to each sensing surface, and is connected with the weighing platform. The scheme is characterized in that: no matter which direction resultant force on the weigher is in, a sensing chip closest to the direction of the resultant force corresponds the resultant force, stress on the sensing chip is maximum, an obtained numerical value is used as the resultant force of impulsive force on the weigher and the gravity of the vehicle, and a system calculates the magnitude of the gravity according to a deflection angle of the sensing chip relative to the direction of the gravity.

Description
Technical field
The utility model relates to a kind of weighing device, especially relates to the automatic weighing device of the vehicle in a kind of the going.
Background technology
Overloading wagon is a major reason that causes traffic hazard, also is the arch-criminal who causes the road surface infringement, and traffic administration department and fortune pipe department have also spent lot of manpower and material resources in order to stop overloading wagon.Dynamic weighing scale through being arranged on the road surface carries out vehicle is weighed in advance, then the suspect vehicle of finding of weighing is in advance carried out weight bridge weighing.Because the degree of accuracy of present dynamic weigher is poor; The error of several kinds of common weighing devices even can reach more than 40%; Like publication number is that CN202066579U discloses a kind of dynamic weighing platform, comprises the title body, claims that body embeds roadbed; Claim that body comprises weighting platform and frame base, quartz weighing sensor is installed on the weighting platform.Weighing platform directly is pressed on 4 quartz weighing sensors through the spheric seating on deck plate top, and weighing platform, frame base and the quartz weighing sensor of weighing are assembled into one, and the height of weighing unit is 120mm.Weighing platform postwelding stress removing, the table top machine tooling guarantees the flatness requirement.Institute says that so this patent documentation thinks that weighing platform helps improving weighing precision through above-mentioned rational Design on Plane and manufacturing, and weighing precision can reach ± 2.5%F.S.But in the high-speed motion process of vehicle, weighting platform can receive the considerable influence of vehicular impact power, must make its weighing data produce bigger deviation.
Summary of the invention
The utility model mainly is to solve the existing in prior technology technical matters not high to the weighing precision of the vehicle in advancing, and a kind of road surface simple in structure, that precision is high automatic weight scale of driving a vehicle is provided.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals: a kind of road surface automatic weight scale of driving a vehicle; Comprise weighing platform, sensor and controller; It is characterized in that described sensor comprises several circular arc sensitive surface; Evenly be placed with some cell bodies on this sensitive surface, be provided with a foil gauge in each cell body, the signal circuit of this foil gauge links to each other with described controller respectively; Sensitive surface is provided with suitable with it arc surface feet, and this feet all links to each other with described weighing platform.Existing weighing device; The vehicle precision of weighing under steam can receive very big influence; Mainly be at the scale plate when receiving the impulse force of vehicle; Its direction of making a concerted effort that can make scale receive on the one hand deflects, on the other hand also can be under the effect of this impulsive force, and the power that weighing comes out is individual bigger than normal a lot.And common scale is only considered the effect of the power of vertical direction when design, and when the direction of power deflected, the data of its weighing can change a lot, and regularity is not strong, is difficult to obtain a weighing accurately through the correction of data.The characteristics of this scheme are; The resultant direction no matter scale receives is towards which side; Must have one corresponding with it with the immediate sensing chip of direction that should make a concerted effort; The stressed of this sensing chip can be maximum, obtains making a concerted effort of impulse force that numerical value receives as scale and vehicle gravity, and system calculates the size of acquisition gravity again with respect to the drift angle of gravity direction through this sensing chip.This mode of weighing has promptly been eliminated the precision problem of answering the common scale that vehicular impact brings.
As preferably, described foil gauge links to each other with the bottom of cell body through a cushion, the gap of a 0.5-2mm of both sides maintenance of foil gauge and cushion and described cell body.When the cushion forward is stressed, this cushion become open less, when cushion receives its positive power that favours; The distortion of cushion is bigger, and its stressed inclination more, under stressed situation of the same size; The cushion distortion is big more, and this scheme has solved adjacent two foil gauges, when stressed size is more or less the same; Be difficult to accurately which stressed bigger problem of judgement, this mode has been amplified the bigger power of inclined degree and has been out of shape the gap on the sheet in the less power of inclined degree.
As preferably, described foil gauge is provided with 11 altogether, the corresponding drift angle of each foil gauge with respect to gravity direction, and this drift angle data storing is in controller.Each foil gauge corresponding one with respect to the drift angle of gravity direction only be that this foil gauge center and circular arc strain face belong to the line of the round heart and the angle of gravity direction.After obtaining maximum measurement data, as long as the size of the gravity that promptly can obtain through this drift angle to be surveyed.
The beneficial effect that brings of the utility model is, solved the existing in prior technology technical matters not high to the weighing precision of the vehicle in advancing, and realized a kind of road surface simple in structure, that precision is high automatic weight scale of driving a vehicle.

Accompanying drawing 2 is structural representations of a kind of sensor of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment:
Like Fig. 1, shown in Figure 2; The utility model is a kind of road surface automatic weight scale of driving a vehicle, and comprises weighing platform 1, sensor and controller, and described sensor comprises several circular arc sensitive surface 2; Establish 11 cell bodies on the described circular arc sensitive surface 2; Be provided with it foil gauge 4 one to one in this cell body, foil gauge links to each other with the bottom of cell body through a cushion 5, and the both sides of foil gauge and cushion and described cell body keep the gap 6 of a 1mm.The signal circuit of this foil gauge links to each other with described controller respectively, and sensitive surface is provided with suitable with it arc surface feet 3, and this feet all links to each other with described weighing platform 1.
When adopting a kind of vehicle weighing of above-mentioned vehicle weighing device; When the wheel on the axletree of vehicle is opened weighing platform; Weighing platform can receive the impulsive force of vehicle, the gravity direction of making a concerted effort to favour of the part gravity of this impulsive force and vehicle, at this moment; A plurality of each foil gauge obtain stress data respectively; This stress data is sent to controller, and the stress data N of the maximum of controller through wherein and the foil gauge that obtains this stress data calculate this with respect to the drift angle α of vertical direction and measure the gravity size that is obtained, and computing formula is following; Gravity G=Ncos α, and then the gravity G that the wheel on each axletree of vehicle is obtained during through weighing platform carries out the gross weight that addition obtains vehicle.
