Description
Technical field
The present invention relates to intelligent transportation field, particularly relate to the vehicle weighing technology of intelligent transportation field, is a kind of dynamic complete-vehicle-type automatic weighing system and method concretely.
Background technology
Current vehicle dynamic weighing system is widely used in the weighing system of the goods carrying vehicles such as freeway toll station, overrun testing station, mine and harbour, for traffic administration, transfinite improvement and Management play an important role.Meanwhile, along with the development of meter overline industry, the requirement of user to product of weighing is also more and more higher.The heavy product of existing sound state meter cannot meet the requirement of user completely.
Weighing of weight metering charging and overrun testing, main single bended plate type, weighing platform formula axle weight scale or the large table top of the static car load truck scale of weighing that adopts realizes.Use along with batch in recent years and promote, axle weight scale and static automobile scale expose significantly not enough and defect:
(1) axle weight scale of application at present all adopts the mode gathering and add and calculate gross weight after axle weighs, when axletree is successively by axle weight scale, claim to obtain the weight of each axle, be gross weight by the summation of each axle of rear calculating completely, weighing precision reaches ± 2.5% within (within speed per hour 15KM).But when vehicle's center of gravity shifts, the heavy deviation of the axle of acquisition is comparatively large, thus cause the gross weight that adds and try to achieve and vehicle actual weight deviation also larger.Increasing human pilot resets the feature of standby dynamic weighing for meter, takes cheating of being weighed lack of standardization to reduce actual car goods gross weight, thus reaches the object escaping Lou toll.
(2) in actual applications; weigh the scene often vehicle condition complexity of car weight; vehicle can be waited in line to weigh usually, pay and unloading etc.; the wheel of vehicle may stop at random on weighing platform, start or reversing etc.; if accurately reversing cannot be identified, the dynamic weighing information that will lead to errors.
(3) existing part toll station employs static scale to make up the shortcoming of axle weight scale, to realize static weighing.Fig. 1 utilizes the oscillogram collected with the sensor matched of static weighing truck scale, and wherein ordinate represents the car weight that static weighing truck scale claims, abscissa representing time.Composition graphs 1 is known: utilize static weighing, can only obtain all the sensors add and weight, when deserve to be called weight reduce time, cannot judge vehicle be reversing or lower scale.Therefore static automobile scale can only adopt the mode of car one scale.Static scale cannot identify the number of axle and the vehicle of vehicle accurately in addition, needs the support of external equipment fetalism recognizer, there will be the situation of losing axle and multiaxis, need again weigh.It can thus be appreciated that the maximum shortcoming of static weighing is: static scale is merely able to calculate gross weight and can not calculates single shaft, and rear car can only wait for that front truck can go up scale after playing scale completely, and traffic efficiency is low, passage rate easily causes traffic congestion comparatively slowly.
Based on the deficiency of above-mentioned axle weight scale and static weighing truck scale, there is a kind of system adopting dynamic weighing truck scale to carry out weighing measurement at present, undertaken being spliced to form a dynamic large scale by 4 weighing platforms, two groups of LOAD CELLS are installed below each weighing platform, share one group of LOAD CELLS in Liang Ge weighing platform lap-joint, have 5 groups of sensors to gather the axle information carrying number of tested vehicle.The oscillogram that the sensor that Fig. 2 is existing this dynamic weighing large scale collects.As can be seen from Figure 2, by the signal of each group of sensor of weighing platform, the number of axle of scale under the heavy and vehicle of the number of axle of scale on vehicle, axle can be calculated, by the axle of vehicle is heavy can the weight of rough calculation stoppage of vehicle on weighing platform, thus when realizing scale on many cars, deduct by the gross weight on weighing platform the method that front truck rests on the weight on scale, also can the weight of rough calculation rear car, realize vehicle dynamic and cross car, the many cars of a scale.But due to this dynamic large scale 4 weighing platforms set by length be all greater than 5 meters, actual cross in car process, by the impact of the factors such as the on-the-spot track gradient, when current rear car distance is less, cannot the axle weight of accurate vehicle, cause the gross weight that accurately cannot calculate rear car.
Therefore, the heavy product of current meter all cannot meet the requirement in current and following owner and market completely in accuracy and high-level efficiency etc.Therefore urgently design a high precision both with static scale, the dynamic large scale of the dynamic complete-vehicle-type automatic Weighing of dynamic balance high-level efficiency and pin-point accuracy can be kept again.
