DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art An orbital alignment, particularly an orbital alignment in a curved section,
Usually, the yaw value is measured manually or by a trajectory measuring device or the like mainly by the threaded crossing method, and a movement amount for correcting the orbit deviation is usually obtained from the yaw value. For example, JP-A-63-272802, JP-A-63-101701
, JP-A-2-96002, and JP-A-6-343
No. 57 proposes a method of calculating a moving amount (deviation amount) from a positive arrow value.

In this method, the amount of movement is obtained at predetermined intervals by sequentially performing discrete calculations based on the relationship between the on-site value of the site and the design value of the arrow (here, the deviation between the two values). Apart from such a discrete method, as a relatively high-speed method, a field average value obtained from a measuring device is filtered by a filter that averages a variation of the site value caused by a trajectory deviation (moving average). To find a reference restoration wave,
There has been proposed a method of checking how the in-situ Masaya value is deviated with respect to the restored wave, and determining the movement amount from the deviation.

[0004]

However, the method using the restoration wave has the following problems. In other words, in the curved section, when the relationship between the restoration wave and the value of the on-site positive arrow is obtained and the movement amount is calculated, even if the actual trajectory is adjusted using the movement amount, the orbit is completely out of order. Is that it cannot be adjusted. For example, as shown in FIG. 10, for a curved section, the trajectory is not immediately connected to a circular trajectory (circular curve section E) having a constant radius of curvature from the straight section H, but gradually through a relaxation curve section F. And is connected to the circular curve section E. In this curve section, especially, the irregularity of the trajectory before and after the transition section F, that is, the connection between the transition section F and the straight section H or the connection section between the transition section F and the circular section E is completely adjusted. I couldn't correct it.

[0005] The present invention provides a method for detecting the amount of movement using a restoration wave.
It is an object of the present invention to obtain an appropriate movement amount in the curved section and to complete the correction of the orbit deviation more completely.

[0012]

According to a first aspect of the present invention, there is provided a method for detecting a moving amount of a curved section of a trajectory of a trajectory, in which a moving average value (restored wave) is obtained by filtering an actually measured on-site positive value. The on-site movement amount is obtained from the relationship with the arrow value, and a design average value (restored wave) is obtained by filtering the design arrow value obtained from the design trajectory alignment in the curved section of the trajectory. A corrected movement amount is obtained from the relationship with the design arrow value, and a movement amount for correcting the trajectory is obtained from a deviation between the on-site movement amount and the corrected movement amount.

The amount of correction movement is a value that has not been considered in the conventional method using a restoration wave. That is, naturally, the curve section on the design does not include the track deviation, and from the arrow value (design arrow value) obtained by the operation or the like based on the design track alignment, the track deviation is calculated. It was because it was thought that the amount of movement to adjust was not expected to come out.

However, it has been confirmed by the inventor that in the method using the restoration wave, the amount of movement can be obtained in a non-negligible form even from the designed orbital alignment, particularly in the curved section. In the curved section, as described above, the transition section is provided to connect the straight section and the circular section. It has been found that the movement amount appears at the connection between the transition curve section and the straight section or the circular curve section despite the design arrow value. In other words, it has been found that a movement amount for adjusting the trajectory occurs despite the trajectory alignment in the design.

[0015] This means that the moving average value is obtained by filtering the on-site value of the actual measurement, and the on-site movement amount obtained from the relationship between the moving average value and the on-site value of the on-site value is based on the design orbital linearity. Indicate that the movement amount appearing in is included as an error. Since this error was not recognized, it was difficult to completely correct the curve section by the conventional method using the restoration wave.

For this reason, in the present invention, the trajectory is not simply adjusted based on the on-site movement amount, but is adjusted based on the deviation between the on-site movement amount and the corrected movement amount obtained from the design arrow value. The amount of movement to correct is required. By doing so, in the method of detecting the movement amount of the curved section of the trajectory by the restoration wave, an appropriate moving amount in the curved section can be obtained, and the correction of the trajectory deviation can be more complete.

Also, instead of filtering a design arrow value obtained from a designed orbital alignment in a curved section of the track to obtain a moving average value, an ideal arrow value is calculated based on the on-site arrow value. The moving average value may be obtained by filtering the ideal value obtained as follows. Even without using the orbital in the design, if the ideal yaw value is calculated based on the on-site sagittal value and filtered to obtain a moving average value, the moving amount from the current orbital alignment is small. This is preferable in that the orbit can be adjusted to an appropriate orbital shape.

Here, the expression “based on the site arrow value” means that, for example, the arrow value in a curved section usually has a trapezoidal shape.
Among the shapes obtained from the on-site positive value pattern, the height of the trapezoid (corresponding to the positive value or curvature of the circular curve section),
Using a trapezoidal element such as the length of the top side or the slope of the left and right sides of the trapezoid, the shape of the trapezoid as an ideal value is determined. In addition, based on the orbital design in the design and the pattern of the design arrow value, the ideal value of the arrow value is calculated by adding the element of the arrow value on the site to the pattern based on the trajectory alignment and the design arrow value pattern. This case is preferable because the deviation from the design is further corrected.

Further, when calculating the deviation between the on-site movement amount and the corrected movement amount, there is a possibility that the whole movement amount may be included in the curve section up to the positional deviation. In such a case, the entire curve section is adjusted. You have to correct it. In order to prevent this, the moving average calculated from the design or ideal arrow is calculated at the position where the degree of coincidence with the moving average calculated from the field is the highest, that is, in the calculation. At the position where the degree of coincidence between the moving average calculated from the design or ideal arrow and the moving average calculated from the site is the highest, the pattern of the local movement and the correction After relatively moving the pattern, the deviation between the on-site movement amount and the corrected movement amount may be calculated to determine the movement amount.

If the method for detecting the amount of movement of a curved section of a trajectory is realized as an apparatus, the following configuration is obtained. That is, the device for detecting the movement amount of the curved section of the trajectory includes a site movement amount calculation unit, a corrected movement amount calculation unit, and a movement amount calculation unit, and the site movement amount calculation unit filters the actually measured site value. A moving average value is obtained, and an on-site moving amount is obtained from a relationship between the moving average value and the on-site positive value, and the corrected moving amount calculating means calculates a design correction obtained from a design trajectory linear shape in a curved section of the trajectory. The moving average value is obtained by filtering the arrow value, and the corrected moving amount is obtained from the relationship between the moving average value and the design right arrow value, and the moving amount calculating means is calculated by the on-site moving amount calculating means. The movement amount is obtained from a deviation between the on-site movement amount and the corrected movement amount calculated by the corrected movement amount calculation means.

[0021] Thus, by the same mechanism as the above-described method for detecting the amount of movement of the curved section of the trajectory, the apparatus for detecting the amount of movement of the curved section of the trajectory by the restoration wave can also obtain an appropriate amount of movement in the curved section. It is possible to complete the mad correction more completely.

Similarly, the above-mentioned corrected moving amount calculating means obtains a moving average value by filtering the ideal arrow value obtained as the ideal arrow value based on the above-mentioned field value. The correction movement amount may be obtained from the relationship between the average value and the ideal arrow value, and the above-described operation and effect may be obtained.

The moving amount calculating means may calculate a moving average value pattern obtained from the design right arrow value or the ideal right arrow value and a moving average value pattern obtained from the on-site positive value. If the movement amount is determined at the position where the degree of coincidence is the highest, the displacement of the entire curved section can be eliminated, and the entire curved section does not need to be corrected.

And a spring for elastically press-contacting the rail surface.

The outputs of the displacement detectors 20, 22, and 24 are subjected to a process of calculating the on-site positive value Vb as shown in the following equation 1 by a positive value calculation circuit 28.

[0027]

(Equation 1)

Here, as shown in FIG. 3, a, b, and c are the measured values of the displacements of the displacement detectors 20, 22, and 24, respectively. The displacement detectors 20, 22, 24 are A ', B',
C ′, the end of the movable rod of the linear displacement detector is brought into contact with the measured rail K1 at points A, B, and C, and the arrow at point B is positively corrected in the field by the threaded crossing method. Arrow value V
as b. FIG. 6A shows a specific example of the output of the on-site positive arrow value Vb.

The on-site positive value Vb is directly used by the arithmetic unit 6
Side, and further to the filter circuit 30. The filter circuit 30 is a low-pass filter,
A frequency higher than the frequency appearing in the positive arrow value is attenuated as an orbital deviation, and the average value Vba is output. This average value Vba
Is as shown by the solid line in FIG. 6B. Then, the average value Vba is also output to the calculation unit 6 side.

In the distance measuring signal transmitter 26, a roller provided at the center of the frame 10 is brought into rolling contact with the head of the rail K1 to be measured.
The turntable is rotated with the progress of the curve section movement amount detection device 2, and a pulse signal is transmitted by intermittently supplying light to an optical switch through a through hole formed on the periphery of the turntable. it can. With this structure, every time the curved section movement amount detection device 2 moves by a predetermined distance, for example, 1 mm, the distance measurement signal transmitter 26 can output one pulse at a time. This ranging signal transmitter 2
The pulse output from 6 is input to the calculation unit 6 side, and the calculation unit 6 performs a process of integrating the traveling distance of the curved section movement amount detection device 2 and specifying each inspection point.

The arithmetic unit 6 is configured as a microcomputer, and includes a CPU 32, a ROM 34, a RAM 36, an input port 38, an A / D converter 40, and an input / output port 42, which are connected by a bus 44.

FIG. 4 is a flowchart showing the curve section movement amount detection processing executed in step (a).

First, an ideal arrow value Vs is set based on the on-site arrow value Vb obtained as shown in FIG. 6A (S10).
00). This is set as shown in the flowchart of FIG. First, as shown in FIG. 8A, the point at which the on-site positive value Vb starts to be biased in the plus or minus direction is 5 points.
A point around 0 m is defined as a start point Ps and an end point Pe (S1
010). The points Ps and Pe at which the on-site positive arrow value Vb starts to be biased in the plus or minus direction may be determined by human eyes, or, if the processing is performed by the arithmetic unit 6, the average value Vba output from the filter circuit 30. However, it may be determined by calculating a point or the like that starts to incline at a gradient higher than a predetermined value.

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 value Vb at a pitch of 1 m (S1020). It is to be noted that up to the preliminary distance of 50 m is included in the area calculation because the curvature component of the curved section may slightly move outside the trapezoid shown in FIG. This is for the purpose of calculating S.

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

[0036]

(Equation 2)

The following equation (3) is derived from the equation (2).

[0038]

(Equation 3)

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

Thus, the pattern of the ideal positive arrow value Vs as shown in FIG. 7A is set. Next, filtering is performed on the ideal arrow value Vs to obtain an average ideal arrow value Vsa.
(Corresponding to a restoration wave) is obtained (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. In FIG. 7B, the pattern indicated by the broken line is the pattern of the ideal arrow value Vs before filtering, and the pattern indicated by the solid line is the pattern of the average ideal arrow value Vsa after filtering. After filtering, it can be seen that the vicinity of the connection between the transition section and the straight section and the vicinity of the connection between the transition section and the circular section are smooth with a slight angle.

Next, based on the relationship between the average ideal arrow value Vsa and the ideal arrow value Vs before filtering, the correction movement amount Ms
(S3000). The method of obtaining the correction movement amount from the relationship between the values of the arrows before and after the filtering is described in the above-mentioned conventional example (Japanese Patent Application Laid-Open No. 63-272802, Japanese Patent Application Laid-Open No. 63-10 / 1988).
No. 1701, JP-A-2-96002 and JP-A-6
In the method of (-34357), the calculation may be performed by calculating the average ideal right arrow value Vsa after filtering as a reference line.

In addition, the correction movement amount Ms may be obtained by the following method. For example, as shown in FIG.
mm orbital deviation, that is, the amount of movement is-
When 7 mm is required, the positive arrow value is +3.5 mm in the opposite direction before and after the -7 mm deviation as shown in FIG. 9B.
Is seen. FIG. 9 shows a straight section as an example,
This is the same in the curved section.

Therefore, the deviation of the ideal sagittal value Vs from the average ideal sagittal value Vsa is represented by the relationship shown in FIGS. 9 (a) and 9 (b).
That is, according to the relation that one deviation on the orbit appears as one deviation and one-half deviation on both sides in the case of the arrow value, the average ideal arrow value Vsa to the ideal arrow value Vs By checking the pattern in which is displaced, it is possible to determine at what position on the trajectory (here, on the ideal trajectory) the movement amount (here, the corrected movement amount Ms) exists.

The resulting corrected movement amount Ms is shown in FIG.
It is shown in (c). Next, the on-site positive value Vb and the filter circuit 3
From the relationship with the average value Vba output from 0, the on-site movement amount M
b is obtained (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 arrow value Vsa is
As shown in FIG. 7B, the corners are smoothed by the filtering, so that the corrected movement amount Ms as an error occurs as shown in FIG. 7C. This is also true for the average value Vba, which is the standard of the site true 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 correction movement amount Ms shown in FIG.

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

[0047]

(Equation 4)

That is, by subtracting the hatched portion (correction movement amount Ms) in FIG.
The movement amount M is obtained as shown in (e). Since the present embodiment is configured as described above, the on-site movement amount Mb
Instead of adjusting the trajectory at
The ideal shift value Vs is processed based on the average ideal shift value Vsa, that is, the restoration wave, and the corrected movement amount M finally obtained is obtained.
By subtracting s, the movement amount M for actually adjusting the trajectory is obtained. In this manner, even in the detection of the movement amount of the curved section of the trajectory by the restoration wave, an appropriate moving amount M in the curved section can be obtained, and the correction of the trajectory deviation can be made more complete. Become.

It should be noted that the present curve section movement amount detecting device 2 can be applied not only to a curve section but also to a 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 moving amount calculating means, and step S5000 corresponds to the processing as the moving amount calculating means.

[Others] In the above embodiment, step S1
At 010 to S1030, the area S of the on-site positive value Vb was calculated to obtain the ideal positive value Vs of the circular curve section.
In addition to this, as shown in FIG. 6A, the start point BCC of the circular curve section and the end point ECC of the circular curve section are determined by the site true value V
It is also possible to obtain the average value of the on-site positive values Vb during the pattern b, obtain the ideal positive values Vs in the circular curve section, and then perform the same processing as in step S1040.

In the processing of step S5000, the movement amount M is obtained from the on-site movement amount Mb and the corrected movement amount Ms as calculated in steps S4000 and S3000. There is a case where there is a positional deviation between the arrow value Vs and the field right arrow value Vb. If this displacement is left unchecked, the final movement amount M may become large as a whole. Therefore, the degree of coincidence by the pattern recognition processing is calculated or judged by human eyes, and FIG.
As shown in the graph, the average ideal arrow value Vsa and the average value V
It is preferable that the displacement d is eliminated by adjusting the positional relationship with ba, and the calculation in step S5000 is performed.

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

In addition, the ideal arrow value Vs may be obtained based only on the site arrow 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 on-site positive value Vb. The processing shown in FIGS. 4 and 5 can be performed on-site by the arithmetic unit 6. However, even if data such as the on-site positive value Vb measured at the on-site is brought back and processed by another computer system, good.

In addition, all of the above-described processing may be performed by a human. In particular, when the ideal arrow value Vs shown in FIG. 8B is obtained from the on-site arrow value Vb as shown in FIG. 8A, human pattern recognition may be used.
