Description
Technical field
The present invention relates to a kind of Weighing method, belong to electronics weighing field based on digital sensor multiple platforms static state railroad track scale.
Background technology
In industries such as petrochemical industry, need to use static state railroad track scale that the tank car that is in the every joint railway under the connection extension state of splendid attire liquid material is carried out accurate weighing.Usually, as shown in Figure 1, reach the length L of determining the track scale weighing platform with the bogie distance L 2 of adjacent tank car according to the distance L between two axles of two bogie outermosts of tank car 1.When the length L of track scale weighing platform greater than the distance L 1 between two axles of tank car, and the length L of track scale weighing platform is less than the bogie distance L 2 of adjacent tank car, by a master scale is that the A scale can carry out independent weighing to every joint tank car, as not satisfying above-mentioned condition, just can not carry out independent weighing to every joint tank car.
But if in a row tank car, the distance L 1 between two axles of each tank car differs greatly, and a standard weighing platform is that the A scale just can not satisfy the requirement of weighing.As shown in Figure 2, adopt the standard weighing platform at the standard tank car, need adopt two master scales to carry out weighing simultaneously at the overlength tank car is A scale and B scale, each scale disposes corresponding instrument respectively, gather instrument by another again the weight data of each weighing platform instrument is added up, obtain the weight of overlength tank car.In above-mentioned weighing system and since two master scales on function fully independently, so can satisfy the requirement of static state railroad track scale standard and static state railroad track scale vertification regulation.But this gathers instrument then is virtual " summation " scale, it is not the scale of a function opposite independent, the a series of performance and the function that do not have independent scale and had, as: can not proofread and correct " summation " scale separately and carry out to regulate at zero point, range, angular difference regulates, nor can control the error etc. of " summation " scale separately.Because " summation " scale weighing error is bigger, so it can not satisfy the requirement of static state railroad track scale standard, can not examine and determine according to the vertification regulation of static state railroad track scale fully.
Summary of the invention
The purpose of this invention is to provide a kind of Weighing method of the multiple platforms static state railroad track scale based on digital sensor, two or more unit formed combination balances of scale combination in any are had independent function of weighing.
The present invention is that the technical scheme that achieves the above object is: a kind of Weighing method based on digital sensor multiple platforms static state railroad track scale is characterized in that:
(1), set up the geocoding of each digital sensor in the weighing system, and be stored in the digital processing unit, digital sensor storage geocoding separately,
(2), set up the quantity of scale in the weighing system, and be stored in the digital processing unit, the quantity of scale comprises unit scale quantity and with the formed combination balance quantity of each unit scale combination in any,
(3), set up the corresponding relation of each unit scale and combination balance and digital sensor geocoding, and be stored in the digital processing unit,
(4), digital processing unit gathers the weight data of each digital sensor, according to the corresponding relation of unit scale and combination balance and digital sensor geocoding, forms the independently information of weighing of each unit scale and combination balance of function,
(5), digital processing unit is by instruction, selected unit scale and combination balance are carried out weight data respectively handle, the information of weighing of output scale.
Weighing system of the present invention adopts digital sensor, utilize each digital sensor to have independent geocoding, and set the corresponding relation of each unit scale and combination balance and digital sensor geocoding, especially also comprise the formed combination balance in unit scale combination back with independent function of weighing, not only weighing precision can not descend, and the independent error of control combination scale, have a series of product standards such as angular difference adjusting, auto zero tracking, range adjusting and rules and examine and determine desired function and performance.Therefore can be applied in multiple occasion.For example, in some weighing systems, both needed to know the overall weight of the thing of being weighed, need to know the weight at some position of thing of being weighed again, need know that as rolling stock factory the wheel load of locomotive, axle weigh, the left side is heavy, the right side heavily reaches gross weight, can by Weighing method of the present invention with a plurality of weighing platforms through various combination, form many combination balances.The present invention is in weighing system, because unit scale and instrument can be shared, therefore, in user-friendly and maintenance, the cost performance of system also is greatly improved, and can not only be suitable for static state railroad track scale, but also can be used for dynamic railway truck scale.

Embodiment
The present invention is based on the Weighing method of digital sensor multiple platforms static state railroad track scale, see shown in Figure 3, at first set up the geocoding of each digital sensor in the weighing system, and be stored in the digital processing unit, digital sensor storage geocoding separately, the geocoding of this digital sensor can be a continuous programming code information, maybe can be the discontinuous coding that does not coincide arbitrarily.Set up the quantity of scale in the weighing system, the quantity of scale comprises unit scale quantity and with the formed combination balance quantity of each unit scale combination in any, and is stored in the digital processing unit, and the quantity of scale is set according to use occasion, normally two or more.Set up the corresponding relation of each unit scale and combination balance and digital sensor geocoding again, and be stored in the digital processing unit, this digital processing unit can adopt the electronic-weighing instrument, or computing machine, or the digital microcontroller system, can symmetrical tuple certificate handle.Digital processing unit is gathered the weight data of each digital sensor, corresponding relation according to each unit scale and combination balance and digital sensor geocoding, form the information of independently weighing of each unit scale and combination balance, have product standards such as angular difference adjusting, auto zero tracking, range adjusting and rules and examine and determine desired function and performance.Digital processing unit is by instruction, selected unit scale or combination balance are carried out weight data respectively handle, export the information of weighing of each scale at last, as showing and carrying out various operational processes, satisfying the requirement of static state railroad track scale standard, and examine and determine according to the vertification regulation of static state railroad track scale fully.
See shown in Figure 4ly, weighing system of the present invention is the static state railroad track scale of three weighing platforms, uses 12 digital sensors altogether, a shared instrument.Instrument can be distributed the address to digital sensor, in this weighing system, the geocoding of 12 digital sensors is respectively from 1-12, wherein the A scale comprises 8 sensors, is made up of three scale body unit modules, and the address is from 1-8, the B scale comprises 4 sensors, the address is from 9-12, and the C scale comprises 12 sensors, and the address is from 1-12.Instrument can be handled respectively the data of the digital sensor of this three platform balance, instrument simultaneously or timesharing show the weight and the status information of three platform balances.By that analogy, when three unit scales, distribute the address by instrument to digital sensor, four combination balances of one-tenth capable of being combined, instrument can be handled respectively the data of three unit scales and four combination balances, instrument can be simultaneously or timesharing show the weight and the status information of seven platform balances.
