Description
Technical field
The present invention relates to a kind of highway load-carrying vehicle accurate weighing system of not stopping, particularly a kind of non-foot length static scale expansion car load weighing system device.
Background technology
China's highway is carried out the weight metering charging system, needs the gross weight of load-carrying vehicle, by the charge of ton km.Freeway management department, the axle weight of restriction load-carrying vehicle, be highway safety.Load-carrying vehicle is set out on a journey, and needs two data, gross weight and axle weight.Therefore, at the entrance of highway, load-carrying vehicle weighing system device is set.Known highway load-carrying vehicle weighing system device, by lever, ground induction coil, the axle identification instrument, static scale, the parts such as correlation light curtain form, the general length 17-21 rice of static scale weighing platform.Lever, ground induction coil, be responsible for bar one car, the clearance weight vehicle.Wheel shaft type and the number of axle of axle identification instrument identification vehicle, set static scale weighing platform long enough, and static scale provides the gross weight of car load on weighing platform.Heavy for existing long vertical (length is greater than 21 meters) meter, this non-foot length static scale is just inapplicable, on weighing platform, fails to lay down car load, can't weigh.With the time two selections are just arranged, or throwing huge fund lengthens weighing platform; The restriction long vertical is set out on a journey.Obviously, two selections are all improper.The weigh difficult problem of long vertical of this non-foot length static scale, reveal.Consult Patent data, only have No. 201220630951.3 patents to relate to this difficult problem.Read over this patent, find this difficult problem, still do not solve.In this patent specification embodiment, "---, average, both obtain the gross weight of vehicle ", mean value, why is the gross weight of vehicle? obviously, be wrong conclusion.How to apply " non-foot length static scale ", to long vertical meter weight, become the inventor's goal in research.
Summary of the invention
For application " non-foot length static scale ", the technical matters heavy to the long vertical meter, the invention provides a kind of non-foot length static scale expansion car load weighing system device.The technical scheme of a kind of non-foot length static scale expansion car load weighing system device of the present invention is: see that Figure of description is shown in Figure 1, in the back of static scale, axle weight scale is set, after the front-wheel of long vehicle drives off static scale, again by axle weight scale, weighed.As long as correlation light curtain does not send the signal of winding up, the single-chip microcomputer industrial control board is thought the imaginary axis, and the weight that gross weight equals the static scale real axis adds the weight of the imaginary axis, thereby realizes completing long vertical meter weight with " non-foot length static scale ".Use the back of static scale that axle weight scale and imaginary axis concept are set, be equal to the length that has extended the static scale weighing platform.If before axle weight scale is weighed, correlation light curtain has sent the signal of winding up, is the foot length static scale, and gross weight equals the weight of static scale real axis.A kind of non-foot length static scale expansion car load weighing system device of the present invention, by ground induction coil one, axle identification instrument, static scale, correlation light curtain, the single-chip microcomputer industrial control board, axle weight scale, ground induction coil two, host computer and display screen form, it is characterized in that, after the static scale weighing platform, axle weight scale is set, the upper surface of axle weight scale is concordant with road surface, and lower four angles of axle weight scale weighing platform respectively arrange a LOAD CELLS.Ground induction coil one is embedded under the road surface of the heavy feeder connection of meter.The axle identification instrument is arranged on ground induction coil one De Youlun road afterwards, and the upper surface of axle identification instrument is concordant with road surface; After the axle identification instrument, static scale is set, static scale is concordant with road surface, and 2N LOAD CELLS is set under the static scale weighing platform.Correlation light curtain is set in the both sides of static scale; Safety island in the static scale left side arranges the single-chip microcomputer industrial control board; Ground induction coil two is set after axle weight scale, ground induction coil two is embedded under the road surface of the heavy channel outlet of meter; In the duty room of the left side of ground induction coil two safety island, host computer is set; On safety island after host computer, display screen is set.Be noted that the static scale weighing platform is the integral body that length is huge, for convenient transportation, during manufacture, be divided into several sections productions that can overlap, 12 meters are divided into 2 sections, and 17 meters are divided into 3 sections, and 21 meters are divided into 4 sections.N equals the hop count of static scale weighing platform+1, and N is the natural number more than or equal to 3, total 2N LOAD CELLS under the static scale weighing platform.Circuit part, see that Figure of description is shown in Figure 2,2N LOAD CELLS under ground induction coil one, axle identification instrument, correlation light curtain, static scale weighing platform, 4 LOAD CELLS under the axle weight scale weighing platform, ground induction coil two are electrically connected to the single-chip microcomputer industrial control board, the single-chip microcomputer industrial control board is electrically connected to host computer, and host computer is electrically connected to display screen.
Principle of work of the present invention: by weight vehicle, sailed into the heavy passage of meter, be pressed onto ground induction coil one, ground induction coil one wakes weighing system up.Subsequently, wheel number and the number of axle of axle identification instrument identification weight vehicle.Rear, correlation light curtain perception weight vehicle arrives, and static scale is measured first axle weight, and two axles are heavy altogether, and three axles are heavy altogether--.If the foot length static scale is non-long by weight vehicle, after correlation light curtain sent the signal of winding up, axle weight scale showed zero, and static scale provides the gross weight of vehicle.If be non-foot length static scale, by weight vehicle, be long vehicle, after correlation light curtain sent the signal of winding up, the gross weight of vehicle equaled static scale and axle weight scale accumulated total.Specifically, ground induction coil one, the axle identification instrument, static scale, all information of axle weight scale upload to host computer through the single-chip microcomputer industrial control board, and host computer is measured first axle weight to static scale, two axles are heavy altogether, three axles are heavy altogether--, add that the imaginary axis is the result accumulation that axle weight scale is measured, and provides gross weight and the axle weight of weight vehicle.When weight vehicle was crossed ground induction coil two, display screen showed accurate gross weight and the axle weight of weight vehicle.
