[0035] Further features of the present invention are more
fully described in the following description of several non
limiting embodiments thereof. This description is included
solely for the purposes of exemplifying the present invention
to the skilled addressee. It should not be understood as a
restriction on the broad summary, disclosure or description of
the invention as set out above.
[0036] In the figures, incorporated to illustrate features
of the example embodiment or embodiments, like reference
numerals are used to identify like parts throughout.
Additionally, features, mechanisms and aspects well-known and
understood in the art will not be described in detail, as such
features, mechanisms and aspects will be within the
understanding of the skilled addressee.
[0037] With reference now to the accompanying drawings, the
present invention broadly provides for weighing apparatus 10
useable to weigh rail wagons or rail cars 30 of a rail consist
as said consist passes along a rail line comprising suitable
rail track 8. In particular, apparatus 10 facilitates such
wagon weight measurement without requiring alteration to the
existing rail line. An example of conventional rail track 8 is
shown in Figure 5, with such rail track 8 comprising foot, web
and head portions, as is known in the art.
[0038] In a typical embodiment, the apparatus 10 comprises
a primary sensor module 12 which comprises two load cells 14
mounted on a primary flection member 16. Apparatus 10 also
includes two secondary sensor modules 18 each comprising a
load cell 14 mounted on a secondary flection member 22.
[0039] The sensor modules 12 and 18 are configured to be
mounted about a foot 8.1 of a rail track 8 so that each
secondary sensor load cell 20 is arranged substantially
opposite to one primary sensor load cell 14 separated by a
portion 8.2 of said foot 8.1, as shown. In this manner, the
primary and secondary load cells 14 and 20 complementarily
form a balanced Wheatstone bridge arrangement whereby
deformation of the rail track, being indicative of a wagon
weight measurement when such a wagon passes over the track 8,
is differentially isolable from ambient characteristics not
indicative of said weight measurement.
[0040] As is known in the art, such a balanced Wheatstone
bridge arrangement is able to facilitate accurate and precise
measurements, as ambient characteristics that may adversely
affect measurements are self-cancelling given that all load
cells typically experience such ambient characteristics to a
similar or comparable extent. The skilled addressee is to
appreciate that such ambient characteristics may include
temperature, vibration, electric noise, electromagnetic
interference (EMI), parasitic resistance, and/or the like. In
one example, each load cell 14 and 20 comprises a strain gauge,
but variations hereon are possible.
[0041] While the primary sensor module 12 is exemplified as
a single unit, it is to be appreciated that in other
embodiments, the primary sensor module 12 may comprises two
separate modules, similar to the secondary modules 18, each
primary module comprising a load cell 14 mounted on a flection
member 16.
[0042] In a typical embodiment, the apparatus 10 includes
a clamping or mounting assembly 28 which is configured to mount
the sensor modules 12 and 18 about the foot 8.1 of the track
rail 8, as shown. Typically, such a clamping assembly 28 clamps
the primary sensor module below the foot 8.1 of the track with
each secondary sensor module on top of a wing 8.2 of the foot
portion 8.1 with said wings 8.2 sandwiched between the
respective primary and secondary sensor modules 12 and 18, as
shown. The sensor modules 12 and 18 may also include some
manner of adhesive or sealant to facilitate mounting about the
foot 8.1 of the rail track 8. Variations on the means of
mounting the apparatus 10 to the track 8 are possible and
expected and included within the scope of the present
invention.
[0043] Each sensor module 12 and 18 generally comprises a
receptacle 24 which is configured to receive a flection member
16, 22 having a load cell 14 mounted thereon facing outward
from said receptacle 24. Importantly, these flection members
16, 22 are typically shaped and/or configured to facilitate
sensing of deformation via the load cell 14, 20 mounted
thereon. In one embodiment, the flection member 16, 22
comprises an arcuate body 26 forming a bridge- or bow-like
configuration, as shown in figure 3, with a load cell 14, 20
mounted on an outside flat surface opposite a thin portion of
said body 26 to facilitate in sensing deformation of the rail
track.
[0044] For example, by such flection members 16, 22 being
shaped and/or configured to facilitate sensing of deformation
via the load cells 14, 20 mounted thereon, accuracy and
precision of weight measurements may be improved. The arcuate
body 26 of the flection members 16, 22 has been found to improve measurement sensitivity, however variations hereon are possible and anticipated.
[0045] To further improve measurement sensitivity, the
flection member 16, 22 may be manufactured from a material
having a Young's modulus substantially unaffected by typical
temperature variations and/or operational environment forming
part of the ambient characteristics, i.e. typical temperature
ranges under which the apparatus 10 is expected to operate,
humidity, vibration, etc. In one embodiment, the flection
member 16, 22 is manufactured from a polycarbonate material or
an acetal plastic having a suitable Young's modulus, but other
materials are apposite and within the scope of the present
invention.
[0046] Similarly, in an embodiment, the receptacle or
housing 24 of each sensor module 12 and 18 is typically
manufactured from a resilient metal, such as steel, but other
material may also be used depending on requirements.
[0047] The skilled addressee will appreciate that the
apparatus 10 generally includes a suitable processor (not
shown) which is arranged in signal communication with the
sensor modules 12 and 18, with the processor being configured
to determine deformation of the track 8 as sensed by the sensor
modules 12 and 18. Typically, the processor is configured to
determine the wagon weight measurement based on output from
the balanced Wheatstone bridge arrangement, as is understood
in the art of signal processing and interpretation.
[0048] The skilled addressee is also to appreciate that the
present invention includes a rail line including weighing
apparatus 10, as described herein, as well as an associated method for weighing a rail wagon 30. Such a method typically comprises the steps of passing the rail wagon 30 over the rail line or track 8, measuring, via an output of the balanced
Wheatstone bridge arrangement of the weighing apparatus 10,
deformation of the rail track 8, and determining, via the
suitable processor, a wagon weight measurement based on such
measured deformation.
[0049] Applicant believes it particularly advantageous that
the present invention provides for apparatus 10 whereby
accurate and precise wagon weight measurements may be
facilitated without requiring alteration or modification of an
existing rail line.
