Description

A kind of contactless Platform Construction Clearance double excitation telemetry
Technical field
The present invention is on a kind of measuring method of contactless railroad platform building line --- platform boundary bidifly Ligh-ranging method, belongs to field of measuring technique.Railroad construction clearance is the necessary guarantee of rolling stock safety, Platform Construction Clearance It is the important component for constituting railroad clearance.
Technical background
Current platform building line measurement is the measurement of human contact's formula, and main survey tool is platform limit measuring scale sum Explicit measuring instrument.The drawbacks of this mode is that survey crew must descend road to be operated, and takes driving station track.It is this to survey Amount mode error is big, is substantially made up of the human error and measurement error of survey crew.
Contact type measurement needs many personal down train station track measurements simultaneously, it is necessary to complete in the time of railway maintenance skylight operation Into measurement, and need to carry the last week and declare, the limited maintenance skylight activity duration is difficult to meet operating personnel to be timely completed station The work of platform gauge periodic measurement.Platform Construction Clearance data are needed to upgrade in time, if can not regularly update, and driving is transported Safety causes very big potential safety hazard.Present metering system is bothersome laborious, and operating efficiency is relatively low.
The problem of in order to solve encountered in above-mentioned measurement process, a set of " platform bound pair laser ranging method " is worked out, This method makes personnel and equipment Bu Xia roads just to complete to measure operation.
The content of the invention
The measuring method of current platform building line is contact, and survey crew must descend road to operate, when limited Interior to complete work, inefficiency, this metering system directly affects traffic safety.To solve this problem, it is of the invention Propose a kind of contactless Platform Construction Clearance double excitation telemetry.The advantage of this method is：Measuring system is used Double excitation non-contact measurement, equipment and tester work on platform, and distance transmission laser and signal receive, accurate meter Calculate limit data.Equipment and survey crew are in place of safety, also eliminate because personnel test and bring train operating safety Hidden danger.This method measurement is time saving and energy saving.Its advantage of contactless platform dividing double excitation telemetry of the invention is fairly obvious：
1. using this method, tester is without completing in defined scope and in the defined time, as long as in train row Sailing gap can just complete.Time is free, and the activity duration is sufficient.For many platforms, the measurement operation of many station tracks, survey crew is only Need away once complete.Operating efficiency can be greatly improved, even if can also in case of emergency be timely completed；
2. using this method, survey crew can measure operation in platform place of safety, not influence the traveling of train to pacify Entirely；
3. the measuring method is easily adapted to general fast railway station Platform Construction Clearance measurement work.Due to general fast railway station " maintenance skylight " number of times is few, and the used time is very short, and it is granted that relatively high speed railway station is more difficult to application.
4. using this method, human error and measurement error are reduced, advantage the most obvious is, without square during measurement Find out vertical point, and when platform is measured, there can be a range of rotation, i.e., it is easy to operate and accurate.

Concrete scheme
Survey crew will survey two groups of data in a measurement point, be respectively：Railroad platform edge and adjacent tracks center line Horizontal range and rail top to platform floor vertical height.
Measuring process is as follows：
1. place survey tool.Survey tool is placed on platform safety line (at about 1 meter of platform edge) outside；
2. determine vertical direction.Laser ranging system enters continuous measuring state, and data display Folding-Screen shows measurement distance, swashs Apart from platform, side rail sideways (accompanying drawing 2), fixes range unit farther out for optical registration.
3. measurement height.By adjusting laser ranging system and horizontal direction angleSent using laser ranging system Rail top face (accompanying drawing 2) of the beam alignment apart from platform side farther out, it can be deduced that triangle (accompanying drawing 5), due to two laser Angle between beam is known α, calculates the air line distance S that double excitation launch point is arrived at the top of rail1(i.e. A2O), program calculation is utilized Derived expression：
β1=arccos [(O5O6 2+OO5 2-OO6 2)/2O5O6×OO5]；
S1=A2O=OO5×sinβ1
Line OA2With horizontal direction angle α1, it is possible to use program calculation goes out H1=A2C×sin(α3)=(A2O+d1)× sin(α3), obtain H1Value, continue to adjust bidifly optical range finding apparatus and horizontal direction angle γ sending beam alignment same direction The reference point of platform edge, can obtain triangle (accompanying drawing 1), can draw a triangle (accompanying drawing 6), can be calculated by program Go out platform boundary to double excitation launch point apart from S2(i.e. BO), utilizes program calculation derived expression：
β2=arccos [(O3O4 2+OO3 2-OO4 2)/2O3O4×OO3]；
S2=BO=OO3×sinβ2
H can be gone out by program calculation2=BC × sin (α2)=(BO+d1)×sin(α2), draw H2, pass through program calculation Import formula H=H1-H2, draw height H.(accompanying drawing 8) (remarks：d1=OC, is that double excitation launch point to range unit fixes rotation The vertical range of shaft axis, this is definite value.)
4. measure horizontal range.Adjust laser ranging system and horizontal direction angleThe double excitation of laser ranging system Beam alignment distance platform farther out side track survey face (accompanying drawing 2), it is triangle (accompanying drawing 4) by two laser beams and rail, Go out S using program calculation3(i.e. A1O), program calculation derived expression is utilized：
β3=arccos [(O1O2 2+OO1 2-OO2 2)/2O1O2×OO1]；
S3=A1O=OO1×sinβ1
By using program calculation L1=A1C×cos(α1)=(A1O+d1)×cos(α1), it can be deduced that horizontal range L1。 Laser ranging system and horizontal direction angle are adjusted again, and the reference point for sending twice beam alignment same direction platform edge is (attached Fig. 1), triangle (accompanying drawing 6) is drawn, platform boundary can be calculated by program to double excitation launch point apart from S2(i.e. BO), Utilize program calculation derived expression：
β2=arccos [(O3O4 2+OO3 2-OO4 2)/2O3O4×OO3]；
S2=BO=OO3×sinβ2
Go out L using program calculation2=BC × cos (α2)=(BO+d1)×cos(α2), draw height L2, utilize program calculation L=L1-L2- D-d, draws horizontal range L value.(accompanying drawing 7) (remarks：D is national standard track gauge, and d is that rail head of rail is wide Degree, d1=OC is the vertical range that double excitation launch point fixes rotation axis to range unit, D, d, d1It is fixed value.)
5. measuring subsequent point, aforesaid operations are repeated.
