Abstract

PURPOSE: To find a proper movement amount in a curved section and to correct the warp of a track more completely in a movement-amount detection method and a movement-amount detection apparatus by means of restored waves. CONSTITUTION: Even in an ideal positive-arrow value which does not contain any warp of a track, a correction movement amount Ms as an error is generated when restored waves are generated by a filtering operation. This can be applied to a mean value Vba as the reference of a site versed sine value Vb, and a site movement amount Mb , in (c), which is found by using the mean value Vba as a reference contains the error of the portion of the correction movement amount Ms. Consequently, when a hatching part (the portion of the correction movement amount Ms) is subtracted from the site movement amount Mb, a precise movement amount M is found as shown in (e). Thereby, even when the movement amount in a curved section of the track is detected by the restored waves, the proper movement amount M in the curved section can be found, and the warp of the track can be corrected more completely.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for detecting a movement amount of a curved section of a track and an apparatus for detecting a movement amount of a curved section of a track,
In particular, the present invention relates to a method and apparatus for obtaining a movement amount for adjusting a trajectory in a curved section of the trajectory.

[0002]

2. Description of the Related Art Trajectory alignment, especially in curve sections, is
It is usual to measure the straight line value mainly by the thread tension type crossing method manually or by a track inspection device, and obtain the movement amount for correcting the track deviation from the straight line value. For example, JP-A-63-272802 and JP-A-63-101701.
JP-A-2-96002 and JP-A-6-343.
No. 57 proposes a method of obtaining the movement amount (deviation amount) from the positive arrow value.

According to this method, the amount of movement is determined at predetermined intervals by sequentially and discretely calculating from the relationship (here, the deviation between the two values) between the on-site positive arrow value and the design positive arrow value. In addition to such a discrete method, as a relatively high-speed method, the on-site Masaya value obtained from the measuring device is filtered by a filter that averages the fluctuation of the on-site Masaya value caused by the trajectory deviation (moving average). To obtain the reference restoration wave,
A method is considered in which how the on-site Masaya value deviates from the restored wave is checked and the amount of movement is determined from the deviation.

[0004]

However, the method using the restored wave has the following problems. In other words, in the curved section, when the travel distance is calculated by obtaining the relationship between the restored wave and the field in-situ value, even if the actual travel path is adjusted using the travel distance, the trajectory is completely out of order. It is a point that can not be adjusted. For example, as shown in FIG. 10, in the curved section, the trajectory is not immediately connected from the straight section H to a circular trajectory with a constant radius of curvature (circular curve section E), but gradually via the relaxation curve section F. Is connected to the circular curve section E with the curvature changed. Within this curve section, especially, the trajectory deviation is completely adjusted before and after the relaxation curve section F, that is, in the connection portion between the relaxation curve section F and the straight line section H or the connection portion between the relaxation curve section F and the circular curve section E. I couldn't correct it.

The present invention is directed to a method of detecting the amount of movement based on a restoration wave.
It is an object of the present invention to obtain an appropriate amount of movement in the above-mentioned curved section and to complete the correction of the trajectory deviation more completely.

[0012]

According to the method for detecting the amount of movement of the curved section of the track according to the first aspect of the invention, the moving average value (restored wave) is obtained by filtering the actually measured on-site positive arrow value, and the moving average value and the on-site positive The field movement amount is obtained from the relationship with the arrow value, the moving average value (restored wave) is obtained by filtering the design positive arrow value obtained from the designed trajectory linear shape in the curved section of the trajectory, and the moving average value The corrected movement amount is obtained from the relationship with the design positive value, and the movement amount for adjusting the trajectory is obtained from the deviation between the on-site movement amount and the corrected movement amount.

This corrected movement amount is a value that has not been taken into consideration in the conventional restoration wave method. In other words, the design curve section naturally does not include the deviation of the trajectory, and the deviation of the trajectory is calculated from the normal arrow value (design normal arrow value) obtained by calculation based on the linear trajectory of the design. This was because it was thought that the amount of movement needed to make a correction would not come out.

However, it has been confirmed by the inventor that, in the method using the restored wave, the movement amount can be obtained in a non-negligible form even from the designed orbital line shape, particularly in the curved section. In the curved section, as described above, the relaxation curve section is provided to connect the straight section and the circular curve section. It has been found that the movement amount appears at the connection between the relaxation curve section and the straight line section or the circular curve section, regardless of the design normal value. That is, it was found that the amount of movement for adjusting the trajectory is generated even though the trajectory is designed linearly.

This is because the moving average value is obtained by filtering the actually measured on-site Masaya value, and the on-site movement amount obtained from the relationship between the moving average value and the on-site Masaya value is used to design the trajectory linearity. It indicates that the movement amount appearing in is included as an error. Since this error was not recognized, it was difficult to completely adjust the curve section by the conventional restoration wave method.

Therefore, in the present invention, the trajectory is not simply adjusted by the on-site movement amount, but the trajectory is adjusted by the deviation between the on-site movement amount and the corrected movement amount obtained from the design positive arrow value. Seeking the amount of movement to correct. By doing so, even in the method of detecting the amount of movement of the curved section of the trajectory by the restored wave, it is possible to obtain an appropriate amount of movement in the curved section, and to complete the correction of the trajectory deviation.

Further, instead of filtering the design straight line value obtained from the designed trajectory line shape in the curved section of the track to obtain the moving average value, an ideal straight line value based on the site straight line value is obtained. The moving average value may be obtained by filtering the ideal positive arrow value obtained as Even if you do not use the orbital alignment in the design, if you calculate the ideal straightline value based on the on-site straightline value and filter it to obtain the moving average value, the amount of movement from the current orbital lineshape will be small. It is preferable from the point that the trajectory can be adjusted to an appropriate orbital shape.

Here, the expression "based on the on-site normal arrow value" means that, for example, the normal arrow value in the curved section is usually a trapezoid,
The height of the trapezoid (corresponding to the positive arrow value or curvature of the circular curve section) among the shapes obtained from the on-site positive arrow value pattern,
The trapezoidal shape as the ideal positive arrow value is determined by using the trapezoidal elements such as the length of the apex side or the gradients of both sides of the trapezoid. In addition, it is not based solely on the on-site Masaya value, but on the basis of the design orbital alignment and the design Masaya value pattern, the on-site Masaya value is added to this to obtain the ideal Masaya value. In this case, the deviation from the design is further corrected, which is preferable.

Further, when calculating the deviation between the on-site movement amount and the corrected movement amount, there is a risk that the positional deviation of the entire curved section may be included in the movement amount. In such a case, the entire curved section is adjusted. You have to be right. To prevent this, at the position where the moving average value calculated from the design positive or ideal positive arrow value has the highest degree of agreement with the moving average value calculated from the on-site positive arrow value, that is, in the calculation. , The moving average value obtained from the design positive value or the ideal positive arrow value and the moving average value obtained from the actual positive arrow value at the position where the degree of coincidence is highest, the on-site moving amount pattern and the corrected moving amount The movement amount may be obtained by moving the pattern relatively and then calculating the deviation between the on-site movement amount and the corrected movement amount.

Further, when the method for detecting the movement amount of the curved section of the trajectory is realized as an apparatus, the following configuration is obtained. That is, the curve section movement amount detection device of the track includes a site movement amount calculation means, a correction movement amount calculation means, and a movement amount calculation means, and the site movement amount calculation means filters the measured site positive arrow value. The moving average value is obtained, the on-site movement amount is obtained from the relationship between the moving average value and the on-site Masaya value, and the corrected moving amount calculation means is a design positive obtained from the designed trajectory linear shape in the curved section of the trajectory. The moving average value is obtained by filtering the arrow values, the corrected moving amount is obtained from the relationship between the moving average value and the design straight arrow value, and the moving amount calculation means is calculated by the on-site moving amount calculation means. The movement amount is obtained from the deviation between the on-site movement amount and the correction movement amount calculated by the correction movement amount calculation means.

Thus, by the same mechanism as the above-mentioned method for detecting the movement amount of the curved section of the trajectory, the apparatus for detecting the movement amount of the curved section of the trajectory by the restored wave can also obtain an appropriate movement amount in the curved section. It is possible to make the correction of madness more complete.

Similarly, the corrected movement amount calculating means filters the ideal straight arrow value obtained as the ideal straight arrow value based on the on-site straight arrow value to obtain a moving average value, and the moving average value is calculated. The correction movement amount may be obtained from the relationship between the average value and the ideal straight line value, and the above-described operational effects are produced.

Further, the movement amount calculating means is configured to calculate the moving average value pattern obtained from the design positive arrow value or the ideal positive arrow value and the moving average value pattern obtained from the on-site positive arrow value. If the movement amount is obtained at the position where the degree of coincidence is highest, the positional deviation of the entire curved section can be eliminated, and the entire curved section need not be adjusted.

[0027]

[Equation 1]

Here, a, b, and c are displacement measurement values of the displacement detectors 20, 22, and 24, respectively, as shown in FIG. The deviation detectors 20, 22, 24 are A ', B',
The end of the movable rod of the linear displacement detector, which is located at C ', is brought into contact with the rail K1 to be measured at points A, B, and C, and the straight arrow at point B is corrected by the thread tension crossing method. Arrow value V

This on-site Masaya value Vb is used as it is for the calculation unit 6
It is output to the side and also to the filter circuit 30. The filter circuit 30 is a low-pass filter,
A frequency higher than the frequency appearing in the positive value as a trajectory deviation is attenuated, and the average value Vba is output. This average value Vba
A specific example of the output of is as shown by the solid line in FIG. Then, this average value Vba is also output to the arithmetic unit 6 side.

In the distance measuring signal transmitter 26, the roller provided in the center of the frame 10 is brought into contact with the head surface of the rail K1 to be measured,
The rotary disc is rotated as the curved section movement amount detecting device 2 advances, and a pulse signal is transmitted by intermittently supplying light to the optical switch through a through hole formed in the periphery of the rotary disc. it can. With this structure, one pulse can be output from the distance measurement signal transmitter 26 every time the curved section movement amount detection device 2 moves a fixed distance, for example, 1 mm. This distance measurement signal transmitter 2

First, the ideal straight line value Vs is set on the basis of the field straight line value Vb obtained as shown in FIG. 6A (S10).
00). This is set as in the flowchart of FIG. First, as shown in FIG. 8A, it is 5 from the point where the site positive arrow value Vb begins to be biased in the positive or negative direction.
A point around 0 m is set as a start point Ps and an end point Pe (S1
010). The points Ps and Pe at which the on-site positive value Vb starts to deviate in the positive or negative direction may be determined by human eyes, or if the processing by the calculation unit 6 is performed, the average value Vba output from the filter circuit 30. However, it is also possible to calculate and determine a point or the like that starts to incline with a gradient of a predetermined value or more.

Next, the area S on the distance axis between the start point Ps and the end point Pe is obtained by accumulating the site positive arrow values Vb at a pitch of 1 m (S1020). It should be noted that up to a preliminary distance of 50 m, it is possible that the curvature component of the curved section may be slightly moved to the outside of the trapezoid shown in FIG. This is because it is included in the calculation of S.

Next, the ideal positive curve shown in FIG. 8B obtained based on the designed length A of the relaxation curve section and the length B of the circular curve section recorded in the curve ledger at the time of design. Arrow value V
Assuming s, the area of the trapezoid is set as the area S obtained in step S1020, and the height of the trapezoid, that is, the ideal straight line value Vs of the circular curve section is obtained by the following equations 2 and 3 (S103).
0).

[0036]

[Equation 2]

From this equation 2, the following equation 3 is derived.

[0038]

(Equation 3)

In this way, the ideal straight line value Vs of the circular curve section is obtained. Next, regarding the relaxation curve section, as shown in FIG. 8B, a straight line is connected from the height of the ideal straight line value Vs of the circular curve section to 0, and this is set as the ideal straight line value Vs of the relaxation curve section (S1040). ).

Thus, the pattern of the ideal positive arrow value Vs as shown in FIG. 7A is set. Next, the average ideal positive arrow value Vsa is obtained by filtering the ideal positive arrow value Vs.
(Corresponding to the restored wave) is calculated (S2000). This filtering process is the same as the filtering process of the filter circuit 30 of the measuring unit 4. The result is shown in FIG. 7B shows a pattern of the ideal straight arrow value Vs before filtering, and a solid line shows a pattern of the average ideal straight arrow value Vsa after filtering. After filtering, it can be seen that the vicinity of the connection between the relaxation curve section and the straight line section and the vicinity of the connection between the relaxation curve section and the circular curve section are smooth with some angles.

Next, from the relationship between the average ideal straight line value Vsa and the ideal straight line value Vs before filtering, the corrected moving amount Ms is obtained.
Is calculated (S3000). The method of obtaining the correction movement amount from the relationship between the positive and negative values before and after the filtering is the conventional example described above (Japanese Patent Laid-Open Nos. 63-272802 and 63-10).
1701, JP-A-2-96002, and JP-A-6-
No. 34357), the average ideal straight line value Vsa after filtering may be calculated as a reference line.

Alternatively, the corrected movement amount Ms may be obtained by the following method. For example, as shown in FIG.
If there is a mm orbit deviation, that is, as a movement amount −
When 7 mm is required, the positive arrow value is +3.5 mm in the reverse direction before and after the displacement of -7 mm as shown in FIG. 9B.
Deviation is seen. Although FIG. 9 shows a straight section as an example,
This also applies to curved sections.

Therefore, the deviation part of the ideal positive arrow value Vs from the average ideal positive arrow value Vsa is represented by the relationship of FIGS. 9 (a) and 9 (b).
That is, according to the relationship that one deviation on the orbit appears as one deviation and a half deviation on both sides of the deviation value, the average ideal deviation value Vsa to the ideal deviation value Vs. It is possible to find what kind of movement amount (here, the corrected movement amount Ms) exists at which position on the trajectory (here, on the ideal trajectory) by checking the pattern in which is deviated.

The corrected movement amount Ms obtained as a result is shown in FIG.
It is shown in (c). Next, the on-site Masaya value Vb and the filter circuit 3
From the relationship with the average value Vba output from 0, the site movement amount M
Find b (S4000). This calculation method is performed in the same manner as in step S3000. On-site movement amount M
b is shown in FIG.

As described above, the average ideal positive value Vsa is
As shown in FIG. 7B, the corners are smoothed by the filtering, so that the correction movement amount Ms as an error occurs as shown in FIG. 7C. This is also true for the average value Vba, which is the reference for the on-site Masaya value Vb. Therefore, the on-site movement amount Mb in FIG. 6C obtained based on the average value Vba is shown in FIG.
This includes an error corresponding to the corrected movement amount Ms shown in (c).

Therefore, the on-site movement amount M is expressed by the following equation 4.
An accurate movement amount M is obtained by subtracting the corrected movement amount Ms from b (S5000).

[0047]

[Equation 4]

That is, by subtracting the hatched portion (correction movement amount Ms) of FIG.
The movement amount M as in (e) is obtained. Since the present embodiment is configured as described above, simply the amount of movement Mb on site
Instead of adjusting the trajectory at
The corrected moving amount M finally obtained by processing the ideal positive arrow value Vs based on the average ideal positive arrow value Vsa, that is, the restored wave.
By subtracting s, the movement amount M for actually adjusting the trajectory is obtained. By doing so, an appropriate amount of movement M in the curved section can be obtained even in detecting the amount of movement of the curved section of the trajectory by the restored wave, and the orbital deviation can be adjusted more completely. Become.

The curve section movement amount detecting device 2 can be applied not only to the curve section but also to the straight section. In the present embodiment, the processing of the filter circuit 30 and step S4000 correspond to the processing as the on-site movement amount calculation means, and steps S1000, S2000, S30.
00 corresponds to the processing as the correction movement amount calculating means, and step S5000 corresponds to the processing as the movement amount calculating means.

[Others] In the above embodiment, step S1
In 010 to S1030, the area S of the site positive arrow value Vb was calculated to find the ideal straight arrow value Vs of the circular curve section.
In addition to this, as shown in FIG. 6A, the starting point BCC of the circular curve section and the ending point ECC of the circular curve section are set to the on-site positive value V.
It may be obtained from the pattern of b, and the average of the on-site straight line values Vb during that period may be obtained as the ideal straight line value Vs of the circular curve section, and then the same processing as step S1040 may be performed.

In the processing of step S5000, the movement amount M is obtained from the on-site movement amount Mb and the correction movement amount Ms which have been calculated in steps S4000 and S3000. There may be a positional deviation between the arrow value Vs and the field positive arrow value Vb. If this positional deviation is left as it is, there is a possibility that the final movement amount M will become large as a whole, so the degree of coincidence in the pattern recognition processing is calculated, or the judgment is made by the human eye, and the result shown in FIG.
As shown in, relative average ideal positive value Vsa and average value V
It is preferable to eliminate the deviation d by adjusting the positional relationship with ba and perform the calculation in step S5000.

In the above embodiment, the ideal positive arrow value Vs is obtained based on the design data and the on-site positive arrow value Vb. However, the ideal positive arrow value Vs is only the design data, that is, the design value. It may be created as the value itself. This way
The movement amount M is a value that returns the state as designed.

In addition to this, the ideal straight line value Vs may be obtained based only on the field straight line value Vb. That is, FIG.
The length A of the relaxation curve section and the length B of the circular curve section in (b) may also be set as preferable shapes according to the pattern of the site positive value Vb. Although the processing shown in FIG. 4 and FIG. 5 can be performed on-site by the calculation unit 6, even if data such as the on-site measurement value Vb measured on-site is brought back and processed by another computer system. good.

Further, all the above-mentioned processing may be performed by a human. In particular, when obtaining the ideal straight line value Vs shown in FIG. 8B from the field straight line value Vb as shown in FIG. 8A, human pattern recognition may be used.
