Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Multifunctional comprehensive track scale disclosed by the invention, as shown in Figure 1, comprise two parallel bearing rails 2, article two, below bearing rail 2, there are 4 independently scale bodies 1, be respectively used to measure detected vehicle 4 wheelshaft weights information, 4 LOAD CELLS 4 are had below each scale body 1, described LOAD CELLS 4 lays respectively at scale body 1 four angles, sensor base plate 5 is had below LOAD CELLS 4, each LOAD CELLS 4 is connected with embedded intelligence weighing instrument respectively by terminal box, and intelligent weighing indicator can draw by signal transacting the weight data that each scale body is subject to; Bearing rail 2 left and right sides above scale body 1 is provided with approach rail 3, approach rail 3 matches in line with corresponding bearing rail 2, in order to reduce impact when vehicle enters bearing rail 2 from approach rail 3, both have rail bridge 6 by transition position, vehicle location sensor is provided with inside bearing rail, for following the trail of the positional information of detected vehicle, between two bearing rails or approach rail, be provided with Train number recognition device, for identifying the vehicle number information of detected vehicle.
Be provided with carrier bar below described scale body, carrier bar adopts box body shape modular construction, and available steel welding is connected into case structure.
By arranging the steady state (SS) at cross-tie and longitudinal tie guarantee scale body 1 position, the longitudinal every side, both sides of each scale body arranges 2 longitudinal ties respectively, and the every side of both lateral sides arranges 4 cross-ties respectively.
In order to regulate height and the level of scale body 1, make LOAD CELLS 4 uniform force, scale body 1 is setting height(from bottom) and level governor also; Multifunctional comprehensive track scale also comprises anti-climbing frame, cover plate.Anti-climbing frame is a mechanical hook-up between track scale approach rail and circuit rail, and it act as and prevents creeping of track for a train; Cover plate be track scale both sides steel plateelement, dust can be prevented, foreign material fall into track scale basis or track scale gap.
The weight signal of each for detected vehicle wheel shaft is passed to embedded intelligence weighing instrument by terminal box by LOAD CELLS respectively, after embedded intelligence weighing instrument signal transacting, pass to host computer, Train number recognition device and vehicle location sensor will obtain signal transmission equally to host computer.Multifunctional comprehensive track scale system disclosed by the invention both static measurement can be detected vehicle car weight information, kinetic measurement can be detected vehicle car weight information again, can also calculate the result of unbalance loading before and after detected vehicle, left and right unbalance loading simultaneously.System Working Principle is as follows:
Static car load metering: be weighed weighing platform on car load, under gravity, electron trajectory weighing platform by weight transfer to LOAD CELLS, LOAD CELLS converts this weight signal to it directly proportional voltage signal, and this voltage signal gives embedded intelligence weighing instrument after being gathered by terminal box, carries out data acquisition by embedded intelligence weighing instrument, measuring and amplifying, filtering, A/D changes, then carries out data processing through embedded host plate, delivers to host computer display display weight data.
Dynamic car load metering: license number recognizer work before weighing apparatus on vehicle, identify Current vehicle vehicle number information and in host computer, show current license number, vehicle, weight information, vehicle weighs, by vehicle location sensor, at this moment host computer starts registration of vehicle alignment sensor signal, follow the tracks of the position of Current vehicle, when vehicle completely on weigh time, gravitational cue is passed to LOAD CELLS by electronic track scale weighing platform, LOAD CELLS converts this weight signal to it directly proportional voltage signal, this signal passes to embedded intelligence weighing instrument by terminal box, the weight data that embedded host plate imports into by analyzing weighing transducer, carry out dynamic logic judgement, accurately calculate in real time and often save vehicle weight, weight data is sent in database server by network simultaneously, when vehicle rear is by vehicle location sensor, namely after train plays weighing platform completely, host computer just can determine the length of railway carriage.Train number recognition device quits work, and the automatic completion logic of embedded host plate judges, host computer measures weighing value by weighing sensor, and according to parking stall after measured, vehicle commander and the speed of a motor vehicle and the actual weight of preserving railway carriage stored in database.
The data of 4 that obtain according to signal processing unit independently electron trajectory weighing platforms, 4 data obtained be added and be complete vehicle weight, compared with the standard gross weight of vehicle, whether known its overloads; According to the known unbalance loading result of the data of independent electron trajectory weighing platform.The axle heavy phase of front axle is added the weight obtaining forecarriage, the axle heavy phase of rear axle is added the weight obtaining trailing bogie, the anterior-posterior balance state of goods vehicle can be judged by the weight of more above-mentioned forecarriage and the weight of trailing bogie; The axle heavy phase being positioned at detected vehicle outside is added and can obtain outboard wheels gross weight, the axle heavy phase being positioned at detected vehicle interior side is added and can obtain inboard wheel gross weight, the left-right balance state of goods vehicle can be judged by more above-mentioned outboard wheels gross weight and inboard wheel gross weight.
A kind of disclosed in patent CN201010520995.6 have the embedded tracks weighing apparatus weighing system surveying unbalance loading function, have employed the whole information of wheel that multiple sensor unit is used for measuring detected vehicle equally, but its sensing unit is set directly at rail bottom or traditional integrated weighing platform bottom, the interference of other wheel load information is unavoidably subject to when obtaining a wheel load information, multifunctional comprehensive track scale provided by the invention, adopt 4 independently scale body can detect each wheelshaft weights information of lorry respectively, decrease weighing signal disturbing, ensure that precision and the accuracy of weighing, and again unbalance-loading detecting device need not be set especially, reach the effect that an equipment is multiplex.
The part that the present invention does not describe in detail is prior art, repeats no more here.Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under general idea prerequisite of the present invention; some changes and improvements can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
