Abstract
The utility model relates to a dynamic electronic automobile scale, which is mainly composed of a load bearing platform, a weighting sensor, an acceleration sensor module, a secondary instrument and a fixed base. The dynamic electronic automobile scale is characterized in that the acceleration sensor module is a force sensor class module with dynamic standard quality values; the load bearing platform and the fixed base are mutually connected and tightly fastened by a plurality of limiting thin steel plates. The acceleration sensor module is used for detecting the dynamic acceleration of a measured object and compensating weighing process; the dynamic weighing precision is enhanced.
Description
The utility model belongs to the metrology and measurement instrument field, is specifically related to a kind of dynamic electric automobile balance.
General dynamic electric automobile balance just with common LOAD CELLS as loading component, dwindle bearing platform horizontal shift gap by positive stop and improve its weighing precision.As patent ZL94217917X disclosed " Dynamic High-accuracy axle metering electronic vehicle weighing apparatus " is exactly to make measuring element with common pillar LOAD CELLS, dwindles a kind of typical structure in bearing platform horizontal shift gap with limited post.When automobile was weighed at the volley, up-down vibration and horizontal shift must take place in bearing platform, because the influence of its acceleration force, weighing precision significantly reduces.
The purpose of this utility model provides a kind of dynamic electric automobile balance at above problem exactly, it carries out dynamic compensation with acceleration sensor module to bearing platform up-down vibration acceleration force, with the horizontal shift of spacing sheet steel restriction bearing platform, thereby improve its dynamic weighing precision.
The utility model is achieved in that
Dynamic electric automobile balance mainly contains bearing platform, LOAD CELLS, acceleration sensor module, secondary instrument and immobilizing foundation and forms.Bearing platform is equipped with some acceleration sensor module, and this acceleration sensor module is after the acceleration system is carried out dynamic mass mensuration, has the force transducer generic module of dynamic standard mass value.In actual the use, can repack in the force transducer type of acceleration transducer and also comprised LOAD CELLS, but must carry out making it have dynamic standard mass value and good acceleration characteristic after dynamic mass measures the acceleration system.Be analyzed as follows:
Fundamental formular: F=ma............................... (1)
During static weighing: gravity W=gross mass m * gravity acceleration g .... (2)
Acceleration calculation: acceleration force F=gross mass m * acceleration a....... (3)
During dynamic weighing: the F=gross mass m * total acceleration (g+a) of making a concerted effort ... .. (4)
When static weighing, promptly gravity acceleration g is the constant definite value in the formula (2), after measuring power value W, can obtain gross mass m value.Gross mass m is a variable, by the dynamic mass m of the LOAD CELLS of influence power value own
1, other quality (as bearing platform and screw etc.) m
2And testee quality m
3Form, after weighing system is made, m only
3It is variable.Be W=mg=(m
1+ m
2+ m
3) g=(m
1+ m
2) g+m
3G puts (m
1+ m
2) g=0, W=m
3G, the dynamic mass m of sensor own in other words
1And all other quality m
2Can lean on instrument " zero setting " and eliminate its influence, thereby accurately obtain the actual mass m of the object of surveying the dynamometry value W of institute
3Value.
In the dynamic weighing process, promptly by will at first measuring the calculating of just weighing after the acceleration a value in the formula (4).When carrying out acceleration analysis in by formula (3), a value is a variable, thereby must make that to measure the dynamic gross mass m of acceleration system architecture be definite value.Force transducer is to carry out surveying work by the strain signal of itself distortion, and sensor divides fixing base and stressed dynamic deformation two parts in theory and is actually an integral body, its dynamic actual mass m
1The accurate mensuration more complicated of value.Acceleration sensor module is to measure the gross mass m=m of acceleration system architecture
1+ m
2+ m
3Be decided to be the standard quality value, make it can accurately measure a value in the dynamic weighing process at any time and LOAD CELLS Dynamic Weighting process compensated calculating, draw the rest mass value of testee.
Dynamic electric automobile balance of the present utility model also can be coupled to each other with some spacing sheet steels between bearing platform and immobilizing foundation, the horizontal shift of restriction bearing platform.
The utility model has been owing to adopted the acceleration sensor module with dynamic standard mass value, and limits the bearing platform horizontal shift with spacing sheet steel, and the check weighing precision of electronic vehicle weighing apparatus is increased substantially.In practical the use, its static weighing precision reaches the III level, and the dynamic weighing precision reaches 0.5%.
Accompanying drawing is embodiment of the present utility model
Fig. 1 is the planimetric map of dynamic electric automobile balance
Fig. 2 is the sectional view of dynamic electric automobile balance
1. bearing platforms among the figure, 2. spacing sheet steel, 3. acceleration sensor module, 4. pressing plate, 5. housing screw, 6. protection steel plate, 7. immobilizing foundation, 8. bearing sensor, 9. secondary instrument.
During dynamic weighing, the load-carrying object affacts on the LOAD CELLS 8 by bearing platform 1 and with the gravity of object and the acceleration force of up-down vibration, and gravity that the dynamic standard quality of acceleration sensor module 3 bodies produces and acceleration force act on this self the force transducer.The output signal of the output signal of LOAD CELLS 8 and acceleration sensor module 3 demonstrates the static weight value of weighed object through after the data processing in secondary instrument 9.
Claims (2)
1, a kind of dynamic electric automobile balance mainly contains bearing platform, LOAD CELLS, acceleration sensor module, secondary instrument and immobilizing foundation and forms, and it is characterized in that: acceleration sensor module is the force transducer generic module with dynamic standard mass value.
2, dynamic electric automobile balance as claimed in claim 1 is characterized in that: be coupled to each other fastening with some spacing sheet steels between bearing platform and immobilizing foundation.
