Description

The present invention relates to a special turnout advancement measurement system, and more specifically, significantly reduces the labor and time required for measuring the advancement of the turnout, and significantly reduces the human error included in the measured value. It relates to a special turnout advancement measurement system that can be reduced.

In the premises of the station, there are turnouts in various situations such as guiding trains from the main line to each departure / arrival platform, guiding trains from the departure / arrival platform to the main line, shunting while waiting for passing trains, and replacing vehicles at the depot. Exists. In particular, at terminal stations where railroad tracks merge and branch from various directions, various turnouts are used to guide trains and vehicles within a limited site.

The types of turnouts can be roughly divided into ordinary turnouts and special turnouts with a more complicated structure. As the ordinary turnout, a single-opening turnout having a line structure in which a straight line is divided into a right side or a left side, a double-opening turnout having a line structure in which a straight line is divided into two symmetrical directions, and the like are widely known.

On the other hand, the special turnout includes a diamond crossing (DC) having a line structure in which two lines intersect, or a single slip switch (SSS) having a line structure in which a crossing line is provided on one side of the diamond crossing (DC). Widely known.

The turnouts are structurally fixed to the sleepers, movable rails (for example, tongue rails) that are configured to be displaceable with respect to the basic rails, lead rails connected to the movable rails, and facing / separating the lead rails. It is composed of V-shaped crossings and the like arranged in a row.

When the load due to the passage of the train is repeatedly applied to the rails constituting the turnout, the rails are displaced (moved) in part or all of the rails. Due to the advancement of the rail, a gap is created between the movable rail and the fixed rail when switching the turnout, and in the worst case, a problem such as non-conversion of the turnout may occur. Therefore, the amount of advancement (movement amount) of the rails (heavy rails, movable rails, slip rails, basic rails, crossings) that make up the branching device is determined by the operator using the water thread tension measurement method described later. The distance to the station is measured periodically, and the worker manually calculates the amount of movement for each station based on the measured distance. Then, the worker judges the quality of the calculated movement amount based on the control value set in advance. If the amount of movement exceeds the control value, the corresponding rail will be repaired or repaired so that the amount of movement falls within the range of the control value.

In the above water thread tension measurement method, a worker stretches a thread (water thread) so as to pass through the center points of two reference piles provided in a form straddling a turnout, and the water thread is measured. As a line, another worker joins the measurement ruler (right angle ruler) to the reference line and sets the measurement ruler parallel to the ground until it reaches the reference line of each station of the rail that constitutes the turnout. This is a measuring method for visually measuring the distance between the two (see, for example, FIG. 6 of Patent Document 1).

In addition, as a turnout advancement measuring jig, it can be attached to a fixed rail contact portion having a part having the same shape as the shape near the bending center point of the fixed rail (heavy rail) and a fixed rail contact portion. , A turnout measuring device (turnout) equipped with a reference part having a reference line extending in a direction perpendicular to (90 °) with respect to the fixed rail contact part and a measuring part (measurement ruler) for measuring the distance from the reference line. (Measuring jig) is also known (see, for example, FIG. 1 of Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-272515

In the water thread tension measurement method in which water threads are stretched on the two reference piles described in Patent Document 1, at least two workers are required to stretch the water threads which are the reference lines for measurement. In addition, a separate worker is required to measure the distance from the reference line to the measuring point with a measuring ruler. As a result, at least three workers are required for the measurement.

Further, in the measurement by the water thread tension method, since the measurement is performed by a ruler with a long thread tension section as a reference line, there is a problem that the thread tension condition (slack) and human error due to human visual measurement are included in the measured value. Furthermore, the worker needs to hit the ruler at a right angle to the water thread, and there is a problem that a certain amount of skill and experience is required for the measurement. In addition, there is a problem in workability, for example, a large amount of time is required for measurement, and manual calculation is required on the spot to calculate the advance amount.

On the other hand, in the measurement of the turnout amount using the above-mentioned turnout measuring jig described in Patent Document 1, since the turnout measuring jig has a reference line for measurement in advance, the turnout measuring jig is fixed to a fixed rail. After setting to (heavy rail), it is possible for one worker to measure the amount of movement of each station on the rail.

However, since the turnout measuring jig has a large external dimension that engages with the left and right turnout rails, it is not easy for one worker to carry the turnout measuring jig and set it on the turnout rail. That is, there is a problem that the above-mentioned turnout measuring jig is difficult to handle.

Further, in the above-mentioned turnout measuring jig, the reference portion of the jig is used as a measurement reference line, and the distance from the reference line to the tip of each movable rail (for example, tongue rail) toward the left / right start point or end point is measured. It is a jig for doing. That is, each crossing intersection of the starting point and the ending point installed at a place away from the reference line cannot be directly measured by the above-mentioned turnout measuring jig. Therefore, for the measurement of the crossing intersection, the conventionally used water thread must be used. As a result, even when the above-mentioned turnout measuring jig is used, at least three workers are required to inspect the turnout. Further, there is a problem that a lot of labor and time are required for inspection of the turnout, coupled with the difficulty of handling the turnout measuring jig.

Further, since the measurement is performed manually using a measurement ruler, there is a problem that the measured value includes a human error as in the water thread tension measurement method.

Therefore, the present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to significantly reduce the labor and time required for the work of measuring the advance amount of the turnout, and the error included in the measured value. The purpose is to provide a turnout advancement measurement system that can significantly reduce the error.

The turnout advance measurement system according to the present invention for achieving the above object includes a measurement target (104) installed at or near each measurement point of a rail constituting the turnout, and the measurement target (104). A surveying instrument (101) that measures the position information of the measurement target (104) by projecting the measurement light onto the measurement target (104) and receiving the measurement light reflected from the measurement target (104), and the surveying instrument (104). It is a turnout advance measurement system (100) provided with a control device (103) for controlling 101), and the surveying instrument (101) automatically searches for and collimates the measurement target (104). In addition to having an automatic tracking function, the control device (103) takes in the position information related to the measurement point measured by the surveying instrument (101) via wireless communication, and determines predetermined distance information based on the position information. (L1, ..., L10) is calculated, and the advance amount of the turnout is calculated based on the distance information (L1, ..., L10).

In the above configuration, since the surveying instrument (101) has an automatic tracking function, one-man measurement by one worker is possible. Further, since the measurement of the position information of each station is performed by the surveying instrument (101), the measurement error (human error) due to the difference of the measurer is eliminated.

Further, the measured position information of each station is transmitted to the control device (103) via wireless communication, and the control device (103) is configured to calculate the turnout advance amount based on the position information. Has been done. That is, in the present invention, since the advance amount of the turnout is automatically calculated (measured) based on the position information of each measuring point, the water thread tensioning work by the operator and the measurement work by the ruler become unnecessary. In addition to this, the manual calculation by the operator is not required, so that the labor and time required for the measurement work of the advance amount can be significantly reduced.

The second feature of the turnout advancement measurement system according to the present invention is that the control device (103) has a voice recognition function capable of recognizing a human voice.

With the above configuration, the worker can remotely control the surveying instrument (101) by his / her own voice. As a result, the worker can use his / her hands for installing the measurement target (104). As a result, the measurement target (104) can be stably installed at or near each station in a stationary state. As a result, the measurement error (human error) due to the runout of the measurement target (104) is eliminated.

Further, in the above configuration, the worker can remotely control the surveying instrument (101) while holding the measuring target (104) with both hands.

The third feature of the turnout advancement measurement system according to the present invention is that the measurement target (104) has a stone tip (104a) installed at the measurement point and a prism body that receives and reflects the measurement light. A column (105) having a surface shape equal to or similar to the surface shape of the rail can be connected between the stone tip (104a) and the prism main body (104b). That is what has been done.

In the above configuration, the measurement target (104) is formed by hitting the pillar (105) laterally with respect to the side surface of the rail against a measuring point (for example, the edge of the rail) where it is difficult to erect the stone tip (104a). Can be stably stopped. This makes it possible to accurately measure a station where it is difficult to erect a stone tip (104a).

The fourth feature of the turnout advance measurement system according to the present invention is that the surveying instrument (101) has an automatic leveling function, and the advance of the rail is advanced from the coordinate values acquired from the surveying instrument (101). It is to calculate the quantity.

A fifth feature of the turnout offset measuring system according to the present invention is that the control device (103) measures when the column (105) is laterally abutted against the rail for measurement. The coordinate value acquired from the surveying instrument (101) is corrected by using the eccentricity of the stone tip (104a) with respect to the side surface (105a) of the pillar (105) as an offset value.

The sixth feature of the turnout offset measuring system according to the present invention is that when the control device (103) measures the rail when the column (105) is abutted against the rail from the vertical direction. The eccentricity of the stone butt (104a) with respect to the cylindrical surface is used as an offset value, and the coordinate value acquired from the surveying instrument (101) is corrected.

In the above configuration, the rail measurement point can be accurately measured by the above correction in a state where the stone tip (104a) is stably installed at a position separated from the rail measurement point by the pillar body (105).

The seventh feature of the turnout advancement measurement system according to the present invention is that the control device (103) measures all the measurements necessary for calculating the turnout amount of the turnout according to the turnout to be inspected.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an explanatory diagram showing a special turnout advancement measuring system 100 according to an embodiment of the present invention.

The special turnout advancement measurement system 100 is a system that enables so-called one-man measurement in which one worker can easily and accurately measure the advancement amount of the special turnout in a short time. As a configuration for that purpose, the surveying instrument 101 automatically tracks the prism 104 and measures the coordinates of the target (measurement point), the precision tripod 102 that stably mounts the surveying instrument 101 on the ground, and the surveying instrument 101. A computer 103 that automatically calculates the advance amount of the special branching device based on the measurement results (coordinate values), a prism 104 that can be set up at the measurement point (station) measured by the surveying instrument 101, and a stab of the prism 104. The special branching device advancement measurement system 100 is configured to include a prism jig 105 for accurately measuring a measurement point where the 104a cannot be set up. Hereinafter, each configuration will be further described.

The surveying instrument 101 is installed by a precision tripod 102 at an arbitrary position in which all the survey points in the special turnout can be captured. The special turnout advance measurement system 100 has a function of automatically setting a reference coordinate system. In addition, when the worker turns on the power of the surveying instrument 101, the surveying instrument 101 automatically adjusts the level and becomes in a measurable state. As described above, the leveling work performed in the conventional total station becomes unnecessary in the special turnout advancement measuring system 100.

In addition, the surveying instrument 101 has an automatic tracking function that automatically tracks the target (prism 104) and performs measurement. Therefore, the collimation work in which the worker catches the prism 104 (target) from the surveying instrument 101, which has been performed in the conventional total station, becomes unnecessary in the special turnout advancement measurement system 100. As a result, in the conventional total station, two workers, a worker who collimates the prism 104 from the surveying instrument 101 and a worker who supports the prism 104, are required for the measurement. In the advance measurement system 100, only one worker can measure the coordinates of each station of the turnout to be inspected.

In addition, the surveying instrument 101 is equipped with a wireless communication standard (wireless network) such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). Therefore, the measured value (coordinate value) of each survey point measured by the surveying instrument 101 is transmitted to the computer 103 via a wireless network such as Bluetooth (registered trademark). The measured value (coordinate value) transmitted to the computer 103 is used to calculate the advance amount (movement amount) of the special turnout. Therefore, the thread tensioning work and the manual calculation work by the worker, which have been performed by the conventional water thread tension measuring method, become unnecessary in this special turnout advancement measurement system 100.

The precision tripod 102 is made of wood that does not expand due to temperature and absorbs the vibration of the surveying instrument 101. In addition, the tip of the leg is composed of a strong stab with steel inserted. As a result, the surveying instrument 101 can be stably installed on the ground.

The computer 103 includes a control operation unit 103a for remotely controlling the surveying instrument 101, calculating the suspension amount, managing the measurement result, and the like, a manual input unit 103b for the worker to manually input, and a computer by the worker. It is provided with a strap 103c for suspending the 103.

A measurement management program that remotely controls the surveying instrument 101, calculates the advance amount, manages the measurement results, and the like is installed in the computer 103. This measurement management program will be described later with reference to FIGS. 2 to 9. The computer 103 has a wireless communication function for communicating with the surveying instrument 101 or other computer equipment. The computer 103 uses Wi-Fi® or Bluetooth® for short-range wireless communication.

The prism 104 includes a stone tip 104a erected at a measurement point, a prism body 104b that reflects measurement light (distance measuring light 101a) incident from the surveying instrument 101 toward the surveying instrument 101, and a worker supporting the prism 104. Therefore, it is composed of a pole 104c. The stone tip 104a is screwed into and attached to the prism main body portion 104b. Therefore, the stone tip 104a is configured to be removable from the prism main body 104b.

The prism jig 105 is a jig for stably standing the stone tip 104a at a measurement point where it is difficult to stably stand the stone tip 104a of the prism 104. The prism jig 105 has the shape of a quadrangular prism and is attached between the prism main body 104b and the stone tip 104a. The wide side surface 105a joins the measurement point to stabilize the prism 104. This will be described later with reference to FIGS. 10 and 11. A male screw portion 105b that is screwed to the prism main body portion 104b is formed on the head. Further, a female screw portion 105c that is screw-bonded to the stone tip 104a is formed on the bottom portion on the opposite side of the head.

The worker taps the v mark at the right end of the cell to display a pull-down menu, and selects the "station name", "turnout number", and "inspection manager" related to the inspection from the pull-down menu.

In particular, by selecting the "turnout number", all the survey points to be measured by the surveying instrument 101 are read from the design database, displayed on the inspection screen 103f described later, and their arrangement is illustrated. The drawing number, type, and number are automatically entered by selecting the turnout number.

FIG. 6 is an explanatory diagram showing an inspection screen 103f of the special turnout advancement measuring system 100 according to the present invention. The term "inspection" as used herein means determining whether or not each movement amount (progression amount) of the turnout is within a preset control value range. Further, the type of the turnout to be inspected here is a movable DC.

The upper left of the screen is the station / measurement distance two-dimensional map 103f1. Here, the arrangement of each survey point measured by the surveying instrument 101 and the predetermined measurement distances L1, ..., L10 calculated based on the coordinates of each of these survey points are shown in a plane. The movement amount of each station is calculated by the computer 103 based on the measurement distances L1, ..., L10.

On the center of the screen is a station area 103f2 that displays a list of each station of the turnout to be measured. The station area 103f2 is for causing the computer 103 to recognize which coordinate value the coordinate value automatically tracked by the surveying instrument 101 is. That is, when the worker taps the station in the station area 103f2 and taps the measurement confirmation button 103f3, the measured value measured by the surveying instrument 101 is the tapped station (for example, the crossing intersection starting point). It is stored as a coordinate value of 3T) in a storage medium such as RAM or ROM in the computer 103. The stored coordinate values will be used in the calculation of the measurement distances L1, ..., L10.

The box on the left side of the measurement confirmation button 103f3 is a tool box 103f4 for the worker to remotely operate the surveying instrument 101. The worker can turn the surveying instrument 101 left or right by tapping the arrow button. Alternatively, the worker can stop the turning of the surveying instrument 101 by tapping the stop button. In addition, this system has a function to stop the guide light so that the operator does not mistake it as an intrusion prohibition light. For example, the operator can stop the guide light of the surveying instrument 101 by tapping the guide light button.

The box above the tool box 103f4 is a turnout-related information box 103f5 that displays the inspection date, the previous inspection date, the station name, the turnout number, the drawing number of the turnout, and the person in charge of inspection. These are automatically displayed based on the input items on the selection screen 103e.

The box below the tool box 103f4 is a crossing intersection / pile-to-pile measurement distance box 103f6 indicating each measurement distance A, B, C, D from the crossing intersection to each pile. The measurement distances A, B, C, and D are not used for calculating the advance amount, but are displayed as reference values in order to grasp the relative position of the reference point.

The measurement distance A is the distance from the crossing intersection starting point 3T to the pile left 1. The measurement distance B is the distance from the crossing intersection starting point 3T to the pile right 2. The measurement distance C is the distance from the crossing intersection end point 4T to the pile left 1. The measurement distance D is the distance from the crossing intersection end point 4T to the pile right 2. Since it is before the start of measurement, each cell of the measured value is blank. Among the values measured in the past, the most recent measured value is displayed as the previous value. Incidentally, since each measurement distance A, B, C, D is a reference value, a control value related to the determination is not provided.

The lower center of the screen is a movement amount display window 103f7 that displays the movement amount (progression amount) for each measurement point. The cell in the movement amount display window 103f7 is blank because it has not been measured. The measurement distance L1 is a distance corresponding to the length of a perpendicular line drawn from the crossing intersection starting point 3T to the pile interstring (the virtual center line connecting the center of the pile left 1 and the center of the pile right 2). The measurement distance L2 is a distance corresponding to the length of the perpendicular line drawn from the crossing intersection end point 4T to the pile string. In this case, the amount of movement of the distance between the crossing intersections is calculated by the computer 103 as (L1-design value) + (L2-design value). If the calculated movement amount of the distance between the crossing intersections is within the control value (-15 mm to +15 mm), it is considered that there is no problem, and a circle is entered in the "determination this time" column. On the other hand, if the calculated movement amount of the distance between the crossing intersections is out of the control value (-15 mm to +15 mm), it is considered that there is a problem, and a cross mark is entered in the "determination this time" column.

Further, the measurement distance L3 corresponds to the length of the perpendicular line drawn from the helix center left 5T (the bent point of the helix rail left 5) to the crossing intersection chord (the virtual center line connecting the two crossing intersections). The distance. The measurement distance L4 is a distance corresponding to the length of the perpendicular line drawn from the center right 8T of the helix (the bent point of the right 8 of the helix rail) to the crossing intersection chord. In this case, the amount of movement of the helix rail with respect to the crossing intersection chord is calculated by the computer 103 as (L3-L4). If the calculated displacement amount of the helix rail with respect to the crossing intersection chord is within the control value (-19 mm to +19 mm), it is considered that there is no problem, and a circle is entered in the "determination this time" column. On the other hand, if the calculated movement amount of the helix rail with respect to the crossing intersection chord is out of the control value (-19 mm to +19 mm), it is considered that there is a problem, and a cross is entered in the "determination this time" column.

The measurement distance L5 is a perpendicular line drawn from the center left 5T of the helix (the bent point of the heft rail left 5) to the inter-pile chord (the virtual center line connecting the center of the left 1 of the pile and the center of the right 2 of the pile). It is a distance corresponding to the length of. In this case, the amount of movement to the left of the helix rail is the measurement distance L5 itself. If the measurement distance L5 is within the control value (-15 mm to +15 mm), it is considered that there is no problem, and a circle is entered in the "determination this time" column. On the other hand, if the measurement distance L5 is outside the range of the control value (-15 mm to +15 mm), it is considered that there is a problem, and a cross mark is described in the "determination this time" column.

Further, the measurement distance L6 is a distance corresponding to the length of a perpendicular line drawn from the starting point 6T at the left tip of the movable rail to the pile interstring (the virtual center line connecting the center of the pile left 1 and the center of the pile right 2). .. In this case, the amount of movement of the movable rail left tip starting point 6T is calculated by the computer 103 as (L5 + L6) -60. If the calculated movement amount of the movable rail left tip starting point 6T is within the control value (-15 mm to + 15 mm), it is considered that there is no problem, and a circle is entered in the "determination this time" column. On the other hand, if the calculated movement amount of the movable rail left tip starting point 6T is out of the control value (-15 mm to + 15 mm), it is considered that there is a problem, and a cross is entered in the "determination this time" column.

Further, the measurement distance L7 is a distance corresponding to the length of a perpendicular line drawn from the movable rail left tip end point 7T to the pile interstring (the virtual center line connecting the center of the pile left 1 and the center of the pile right 2). .. In this case, the amount of movement of the movable rail left tip end point 7T is calculated by the computer 103 as (L7-L5) -60. If the calculated movement amount of the movable rail left tip end point 7T is within the control value (-15 mm to + 15 mm), it is considered that there is no problem, and a circle is entered in the "determination this time" column. On the other hand, if the calculated movement amount of the movable rail left tip end point 7T is out of the control value (-15 mm to + 15 mm), it is considered that there is a problem, and a cross is entered in the "determination this time" column.

At the bottom of the screen, "Save", "Voice disabled", "Crossing intersection", "Display switching", "Coordinate confirmation", and "Back" icons are arranged. Therefore, when the worker taps the "Save" icon, the displayed inspection result is saved.

In addition, when the worker taps the "Voice disabled" icon, voice recognition is disabled (OFF), for example, "Voice disabled" is changed to "Voice enabled", and the icon also corresponds to "Voice enabled". It changes to one. In this case, by tapping the "Voice enabled" icon again, the voice recognition is enabled (ON), and the "Voice enabled" icon is switched to the "Voice disabled" icon. Note that voice recognition is normally set to enable (ON) as a default value.

Further, the worker can select either "crossing intersection chord" or "crossing or midpoint intersection string" by tapping "crossing intersection". The term "crossing or midpoint chord" as used herein means a virtual center line connecting the crossing or midpoint of the starting point and the crossing or midpoint of the ending point. Further, the "crossing or midpoint of the crossing part" here means the midpoint of the side facing the apex in an isosceles triangle having a predetermined equal length two sides forming the apex with the crossing intersection as the apex. ing.

In addition, the worker can change the display contents on the screen by tapping the "display switching" icon. For example, by tapping the "display switching" icon, the browsing screen 103g described later can be displayed.

In addition, the worker can display a list of coordinate values of each station measured by the surveying instrument 101 (coordinate confirmation screen 103h described later) by tapping the "coordinate confirmation" icon.

The worker can also exit the screen at the same time as ending the inspection by tapping the "Back" icon. Next, the browsing screen 103g will be described.

FIG. 7 is an explanatory diagram showing a viewing screen 103 g of the special turnout advancement measuring system 100 according to the present invention. Each measurement distance L1, ..., L10 calculated based on the coordinates of each station is displayed in each cell of the input value. Each movement amount calculated based on the measurement distance is displayed in each cell of the movement amount calculation formula. Each movement amount is determined based on each control value. If each calculated movement amount is within the range of each control value, it is considered that there is no problem, and a circle is displayed in each cell of "this time judgment". On the other hand, if each calculated movement amount is out of the control value range, it is considered that there is a problem, and each cell × mark of “this time judgment” is displayed.

At the bottom of the screen, icons for "display switching", "coordinate confirmation", and "remeasurement" are arranged. Therefore, if there is a movement amount marked with a cross in the "this time judgment", the worker can return to the inspection screen 103f and remeasure each movement amount by tapping the "remeasurement" icon. ..

Further, the worker can display, for example, the main screen 103d by tapping the "display switching" icon.

Further, the worker can display the coordinate confirmation screen 103h described later by tapping the "coordinate confirmation" icon. Next, the coordinate confirmation screen 103h will be described.

FIG. 8 is an explanatory diagram showing a coordinate confirmation screen 103h of the special turnout advance measurement system 100 according to the present invention. The coordinate confirmation screen 103h displays the coordinate values (X coordinate, Y coordinate, Z coordinate) of each station measured by the surveying instrument 101. The reference coordinate system for measurement is automatically set by the special turnout advancement measurement system 100.

Therefore, the measurement distances L1, ..., L10 displayed on the viewing screen 103g of FIG. 7 are calculated by the computer 103 based on the coordinate values of the measurement points displayed on the coordinate confirmation screen 103h. .. The calculated measurement distances L1, ..., L10 are used in calculating the movement amount of each station. Next, the setting screen 103i will be described.

FIG. 9 is an explanatory diagram showing a setting screen 103i of the special turnout advancement measuring system 100 according to the present invention. Here, as a communication setting, a wireless communication standard for transmitting / receiving data to / from the surveying instrument 101 is selected. Further, as a setting of design values, for example, input each design value of the start point and the end point of the turnout required when calculating the movement amount for the distance between crossing intersections (measurement distances L1 and L2 in FIG. 6). To do.

As another setting, enter the offset. The offset is set, for example, for the shaped rails 5, 8 and the movable rails 6, 7, 9, 10. In the case of the flat rail left 5 or the flat rail right 8, it is extremely difficult to stably install the stone tip 104a of the prism 104 because the flat center left 5T or the flat center right 8T to be inspected has a convex shape. Therefore, in the case of the flat rail left 5, the prism 104 is installed on the outside of the concave rail. Therefore, it is necessary to consider the offset described below for the measured values of the helix center left 5T or the helix center right 8T.

As shown in FIG. 10, between the installation position of the prism 104 and the offset center left 5T of the inspection target, the radius (= 4.5 mm) and the rail width (= 65 mm) of the stone tip 104a of the prism 104 There is an offset corresponding to the sum of (= 69.5 mm). Therefore, it is necessary to correct the actual measured value (coordinate value of the prism 104) based on the offset (= 69.5 mm) for the coordinates of the helix center left 5T and the helix center right 8T. However, the offset value changes according to the width of the rail.

Similarly, for example, in the case of the movable rail left starting point 6T, since the movable rail left tip starting point 6T to be inspected is a flat surface, stable installation is extremely possible even when the prism 104 is applied from the lateral direction. difficult. In this case, by attaching a prism jig 105 having a square prism between the prism main body 104b and the stone tip 104a, the side surface 105a of the prism jig 105 is joined to the flat surface at the tip of the movable rail, and the prism 104 is movable. It will be stably installed at the tip of the rail. Therefore, it is necessary to consider the offsets described below for each measured value of the movable rail left tip starting point 6T and the movable rail right tip ending point 7T, and the movable rail right tip starting point 9T and the movable rail right tip ending point 10T. is there.

As shown in FIG. 11, in the movable rail left starting point 6 from the installation position of the prism 104 and the movable rail left tip starting point 6T to be inspected, the short side length of the side surface 105a of the prism jig 105 ( There is an offset corresponding to a half value (= 6 mm) of (= 12 mm). Therefore, the actual measured values (coordinate values of the prism 104) are the coordinates of the movable rail left tip starting point 6T, the movable rail right tip ending point 7T, the movable rail right tip starting point 9T, and the movable rail right tip ending point 10T. Needs to be corrected based on the offset (= 6 mm). Next, the reproducibility result will be described.

FIG. 12 is an explanatory diagram showing the reproducibility result of the measured value by the special turnout advancement measuring system 100 according to the present invention. This shows the measurement difference relating to the measurement distances L1, ..., L10 when the same measurement point (FIG. 12) is measured twice in total by different workers once on the same day. The measurement difference is assumed to be the value obtained by subtracting the second measurement value from the first measurement value. In addition, as reference values, the measurement distance A from the crossing intersection starting point 3T to the pile left 1 and the measuring distance from the crossing intersection starting point 3T to the pile right 2 are not directly related to the calculation of the movement amount of each station. B, the measurement distance C from the crossing intersection end point 4T to the pile left 1 and the measurement distance D from the crossing intersection end point 4T to the pile right 2 are also shown.

From FIG. 12, it can be seen that the measurement distances other than the measurement distance L3 and the measurement distance L5 are all within ± 2 mm. Regarding the measurement distance L5, a measurement difference of 4 mm occurred. It is considered that this is because the actual measuring point is outside the helix rail left 5, and the radius of curvature R of the abutment stone tip 104a does not match well with the outside of the helix rail left 5. Therefore, it is considered that the prism jig having a shape similar to that of the prism 104 is separately connected between the prism main body 104b and the stone tip 104a on the outside of the left 5 of the helix rail so that the prism jig can be accommodated within ± 2 mm. .. Regarding the measurement distance L3, the distance measurement accuracy of the surveying instrument 101 alone is ± 3 mm, and it is considered that there is no particular problem because it is within that range.

From FIG. 12, it can be seen that the measured value by the special turnout advancement measuring system 100 does not depend on the skill and experience of the worker, and the measurement error due to the difference between the workers is small.

As described above, according to the special turnout advancement measurement system 100 according to the embodiment of the present invention, the labor and time for measuring the advancement amount of the special turnout are significantly reduced, and the measurement value is obtained. It becomes possible to significantly reduce the human error included.

The surveying instrument 101 has an automatic tracking function that automatically tracks the target prism 104. The coordinates (measured values) measured by the surveying instrument 101 are transmitted to the computer 103 via wireless communication such as Wi-Fi (registered trademark), and the movement amount of each survey point is instantly and automatically calculated. Good or bad is judged instantly and automatically. As a result, it becomes possible for one worker to easily perform the measurement of each station related to the advance amount of the special turnout and the inspection of the advance amount in an extremely short time.

Further, the computer 103 has a voice recognition function. This enables remote control of the surveying instrument 101 by voice. As a result, the worker can use both hands to support the prism 104, whereby the runout of the prism 104 can be suitably prevented.

Further, the prism 104 is configured so that a prism jig 105 having a square prism can be coaxially connected between the prism main body portion 104b and the stone tip 104a. The prism jig 105 is joined on the side surface 105a with respect to the vicinity of the station. As a result, the prism 104 can be installed via the prism jig 105 at a station where it is difficult to stably install the stone tip 104a. As a result, even a surveying point where it is difficult to stably install the stone tip 104a can be accurately measured by the surveying instrument 101.

The computer 103 also includes a strap 103c. As a result, the worker can remotely control the surveying instrument 101 while holding the prism 104.

Further, the computer 103 is configured to display all the measuring points and design values necessary for calculating the advance amount according to the turnout to be inspected on the inspection screen 103f. This makes it possible to prevent measurement omissions by workers.

Further, the computer 103 is configured to illustrate the arrangement of all the measuring points necessary for calculating the advance amount on the inspection screen 103f. As a result, it is possible to prevent the operator from misidentifying the measurement location.

The special turnout advance measurement system 100 according to the embodiment of the present invention can be used not only for diamond crossing (DC) but also for single slip switch (SSS), double slip switch (DSS) or other special turnouts. It is applicable to.

Further, as the shape of the prism jig 105, a cylindrical body or an elliptical pillar body may be used in addition to the square pillar body depending on the shape of the station.
