The utility model comprises a base, two or more unit scales, a junction box and a meter, the unit scale comprises a sensor base fixed on the base, a digital sensor installed on the sensor base, and a scale body formed by a through bearing beam and a deck plate, the digital sensor which is installed on each unit scale is provided with a given address coding, the digital sensor of each unit scale is connected with the junction box, an output interface of the junction box is connected with an input interface of the meter via a signal cable, the meter outputs and displays the weighing information of the unit scales and a combined scale which is combined by the unit scales and provided with an independent weighing function. A pluralities of the unit scales of the utility model use one meter which can independently display the weighing information of each unit scale and the independent combined scale combined by unit scales, can be operated and maintained conveniently by users and also can be used in a moving track scale, and cost performance of the system is increased largely.
Description
Technical field
The utility model relates to a kind of multiple platforms static state railroad track scale based on digital sensor, belongs to the electronic-weighing field.
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 to " summation " scale separately and carry out that auto zero is followed the tracks of, range is regulated, angular difference is regulated, 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 utility model provides the multiple platforms static state railroad track scale based on digital sensor, and the shared instrument of a plurality of unit scale can each unit scale weighing information of independent displaying and the weighing information of the independently combination balance that is combined to form by the unit scale.
The utility model is that the technical scheme that achieves the above object is: a kind of multiple platforms static state railroad track scale based on digital sensor, comprise the basis, two or more unit scale, terminal box and instrument, the unit scale comprises the sensor holder that is fixed on the basis, be installed in the digital sensor on the sensor holder, the scale body that constitutes by flute profile carrier bar and deck plate, be installed in the geocoding that digital sensor on each unit scale has setting, digital sensor thereto on each unit scale, the output interface of terminal box inserts the input interface of an instrument by signal cable, instrument output and display unit scale and claimed the information of weighing of the combination balance with independent function of weighing that is combined to form by the unit.
Each unit scale of the utility model adopts digital sensor, the shared instrument of a plurality of unit scale, utilize each digital sensor to have independent geocoding, make the corresponding relation of each unit scale and combination balance and digital sensor geocoding, so weighing information of the independently combination balance of can each unit scale weighing information of independent displaying and being combined to form by the unit scale, combination balance not only can not reduce weighing precision, and the error of control combination scale separately, as carry out angular difference and regulate, auto zero is followed the tracks of, a series of rules calibratings such as range adjusting, performance and function satisfy the requirement of static state railroad track scale standard fully, can examine and determine according to the countries concerned's vertification regulation, 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, needed to know the weight at some position of thing of being weighed again, as rolling stock factory need know the wheel load of locomotive, axle is heavy, the left side is heavy, the right side heavily reaches gross weight.The utility model can be shared owing to the unit scale, and adopt an instrument, and 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.
