Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for measuring and analyzing a rail clearance and a rail temperature formed at a rail rail joint.

[0002]

2. Description of the Related Art A railroad rail is formed by connecting a plurality of rails, and this joint portion is called a rail clearance. Since the rail expands and contracts as the temperature changes, the amount of play also changes with the temperature change. If this amount of play is not sufficient, axial stress will be generated inside the rail at high temperatures, and this will cause a rail overhang accident. Further, if the amount of play is too large, the impact when the vehicle passes becomes large and the riding comfort deteriorates, and it also causes damage to the rails and breakage accidents of the joint plate bolts particularly at low temperatures (winter season). Therefore, it is very important for the maintenance and management of railways to properly manage the amount of rail clearance, and in the past, on semi-main lines and important side lines where mechanical measurements cannot always be performed by an automatic clearance measuring device, A portable rail clearance measuring device is used for maintenance management of the above (Japanese Utility Model Publication No. 6-39656, Japanese Utility Model Publication No. 7-18961).
Issue).

In the rail clearance measuring devices disclosed in these publications, a measurement block having a triangular tapered surface and supported by a spring is inserted into the rail clearance at the rail measuring point, and in this state, the reference surface is set to the rail surface. By pressing it, the amount of rail clearance corresponding to the insertion length of the measurement block is measured. Further, in order to analyze the rail clearance, it is necessary to measure the temperature at the same time when the rail clearance is measured. Therefore, when the measurement block is inserted into the rail clearance, the temperature of the rail is simultaneously measured by the temperature sensor.

As described above, in the conventional portable rail gap measuring device, the measurer inserts the measuring block into the rail gap at each measuring point, measures the rail gap in that state, and simultaneously measures the rail temperature at that time. Then, those values are stored in the memory. Then, after the measurement at all the rail measurement points is completed, it is made to analyze whether or not each rail clearance is in an appropriate state based on the obtained rail clearance and rail temperature.

In addition, in the rail clearance measuring device, a set I of rail groups to be measured from the host computer is prepared in advance.
Each rail identification number of the rail group identified by D (set number, set name, etc.) or its rail set ID is downloaded. In the rail gap device, when they are downloaded, an area for storing the rail temperature and the rail gap amount in each rail gap is secured corresponding to the rail identification number. Further, with respect to the downloaded rail identification number, a reference point is usually set for each set ID. The measured values of the rail temperature and the rail clearance are sequentially measured from this reference point and stored in the storage area.

[0006]

However, since the reference point of the rail group is fixed on the host computer side in the above-described rail clearance measuring device, the measurement of the rail group of one set ID is completed, and the next When attempting to measure the rail group of the set ID, it is necessary to return to the reference point and start the measurement from the reference point again, which causes a problem of burdening the measurer. For example, when a set of up and down lines between specific stations are respectively set, the reference points of the up and down lines are set to the same position, but when the measurement of the up line is completed, the reference points are set again. You will have to go back to and measure the down line. In such a measuring method, if all the measurements are completed and the method is to return to the reference point at the end, the measurer is forced to make two round trips in total despite measuring only one way for each of the up and down lines. Therefore, when the distance from the reference point to the measurement end point is long, the burden on the measurer is large and the measurement takes a long time.

An object of the present invention is to provide a rail temperature or play distance measuring device which can efficiently measure the rail temperature or play distance and reduce the burden on the measurer.

[0008]

The present invention is configured as follows to solve the above problems.

(1) A temperature sensor for measuring the rail temperature, a storage section having a rail temperature storage area corresponding to the rail identification number, and a forward order for measuring the rail temperature in a predetermined direction. Measurement order input means for setting whether to perform or reverse order to measure in the opposite direction, and when the measurement order set by the measurement order input means is the forward order, the rail identification numbers are sequentially displayed in the forward order. The rail temperature measured by the temperature sensor is sequentially stored in a storage area corresponding to the displayed rail identification number, and when the measurement order set by the measurement order input means is the reverse order, the rail identification numbers are sequentially displayed in the reverse order. And a control unit for sequentially storing the rail temperature measured by the temperature sensor in a storage area corresponding to the displayed rail identification number.

The present invention relates to a rail temperature measuring device which is necessary when the amount of play of a rail is measured and analyzed. The device has an area for storing the rail temperature corresponding to the rail identification number.Each time the rail identification number is displayed, the temperature measured by the temperature sensor is sequentially stored in the area corresponding to the rail identification number. Go. At this time, the order in which the rail identification numbers are displayed follows the order set by the measurement order input means. If the set order is forward, the rail identification numbers will be displayed sequentially in a predetermined direction, and if the reverse order is set, the rail identification numbers will be displayed sequentially in the opposite direction to the predetermined direction. . Here, the normal order is a measurement order in a predetermined direction, and the reverse order is a measurement order in the opposite direction. According to this, for example, when performing the measurement of the up line and the down line, after measuring up to the measurement end point of the up line in the up line, set the measurement order in reverse order, reverse the down line from that position. You can proceed in the direction and perform measurements. Then, since the up and down lines can be measured in one round trip, the burden on the measurer is reduced, the time required for the measurement is shortened, and the efficiency can be improved.

(2) A set ID designating means for designating the identification of the pre-classified rail group as a set ID is provided, and the rail temperature is measured with respect to the rail of the set ID designated by the set ID designating means, The setting of the measurement order by the measurement order input means is valid only immediately after the set ID is designated by the set ID designating means.

The measurement order input is valid only immediately after the set ID is specified by the set ID specifying means. As a result, it is possible to prevent the measurement order from being changed in the middle of measurement when the measurement for the rail group of a certain set ID is not yet completed. Since it is impossible for the measurement order to be changed in the middle of measurement, it is possible to consider that the measurement order change operation in the middle of measurement is an erroneous operation. Therefore, by making the setting of the measurement order by the measurement order input unit valid only immediately after the set ID is specified by the set ID specifying unit, it is possible to prevent the malfunction due to the above-mentioned erroneous operation. The set ID is an ID for identifying a group of assembled rails, and is represented by, for example, a set number or a set name.

(3) A measurement block having a triangular tapered surface and supported by a spring is inserted into the rail play, and the reference surface is pressed against the rail surface in this state, so that the rail corresponds to the insertion length of the measurement block. Measure the amount of play,
At the same time, in a rail clearance measuring device that measures the rail temperature by a temperature sensor arranged on the reference plane, a storage unit having a storage area for the rail temperature and the rail clearance corresponding to the rail identification number, and a rail temperature and the rail clearance. The measurement order input means for setting whether the measurement order of is a forward order of measuring in a predetermined direction or a reverse order of measuring in a direction opposite to that direction, and the measurement order input by the measurement order input means is a positive order. In the case of the order, the rail identification numbers are sequentially displayed in a normal order, and the rail temperature measured by the temperature sensor and the rail clearance measured by the measurement block are sequentially stored in the storage area corresponding to the displayed rail identification number. When the measurement order input by the measurement order input means is the reverse order, the rail identification numbers are sequentially displayed in the reverse order and the rail temperature measured by the temperature sensor and the measurement block are displayed. Tsu and rail Joint Gap weight measured by click and characterized in that it comprises a control unit for sequentially storing in a storage area corresponding to the rail identification number the display.

The present invention relates to an apparatus for measuring the rail temperature and the rail clearance at each measurement point. A rail that measures the rail clearance corresponding to the insertion length of the measurement block by inserting the measurement block supported by a spring that has a triangular tapered surface into the rail clearance and pressing the reference surface against the rail surface in this state. In the idle measurement device, the above-mentioned Japanese Utility Model Publication No. 6-39656 or Japanese Utility Model Publication 7-1.
No. 8961 is disclosed. In the present invention, the rail temperature is simultaneously measured when the rail clearance is measured using this device. Therefore, the rail temperature and the rail clearance are sequentially stored in the storage unit in correspondence with the rail identification number. Regarding the order of measurement, as in the case of (1) above, in the forward order, the measurement is performed in a predetermined direction, and in the reverse order, the measurement is performed in the opposite direction. .

1 is a side view and FIG. 1B is a front view of a rail clearance measuring device according to an embodiment of the present invention. Further, FIG. 6C is a diagram showing a state when measuring the amount of rail clearance.

The measuring block 1 has a triangular tapered surface, and is supported by a spring provided inside the apparatus so as to be movable in the direction of the arrow in the figure. The rail clearance measuring device main body 2 has a reference surface 20, and by pressing the reference surface 20 against the rail surface with the measurement block 1 inserted in the rail clearance 13d of the rail 13 as shown in FIG. A rail clearance amount corresponding to the insertion length of the measurement block 1 is measured. Further, as described later, the temperature of the rail head is measured by the temperature sensor provided on the reference surface 20 at the same time when the rail clearance is measured. When measuring the temperature at the bottom of the rail, the measurement block 1 is applied to the abdomen of a rail having an I-shaped cross section, and the rail clearance measuring device body is pushed horizontally until the reference surface 20 abuts the abdomen. In this embodiment,
The rail temperature is detected by the temperature at the bottom of the rail. To detect the temperature at the bottom of the rail, it is necessary to press the reference surface 20 against the abdomen of the rail, but from the temperature of the rail head obtained by pressing the reference surface 20 against the rail head by the method described later. The temperature at the bottom of the rail can be calculated. At this time, since the rail clearance is measured at the same time, it is possible to simultaneously obtain the rail clearance and the temperature of the rail bottom portion by one operation.

The liquid crystal display 21 displays a rail identification number to be measured, a track section, a measurement result and the like.

As the input keys, the enter key 22, the reference key 23, the light key 24, the power key 25, the zero key 2
6, a cursor key 27 and an order key 28 are provided. The confirm key 22 is operated when confirming the measurement result displayed on the liquid crystal display 21. The reference key 23 is operated when the reference point of the rail is designated and the temperatures of the rail head and the rail bottom are measured. The reference point refers to a point in the rail group corresponding to one set number, where there is a rail serving as a starting point for measurement. Once the reference point is determined, measurement will be performed sequentially from that point. Here, other points are referred to as measurement points with respect to the reference point. The light key 24 is operated when the backlight of the liquid crystal display 21 is turned on or off.
The power key 25 is operated when the power of the device is on or off. The zero key 26 is operated when the rail clearance is zero (the measurement block 1 cannot be inserted into the rail clearance). The cursor key 27 is operated when designating the data displayed on the liquid crystal display 21. Order key 28
Is operated when the measurement order of the rail clearance is reversed. The sequence key 28 is operated, for example, when an up line corresponding to one set number is measured and then a down line corresponding to another set number is subsequently measured. By operating the sequence key 28, it is not necessary to return to the original measurement start point and start the measurement of the down line after the measurement of the up line. It is possible to make measurements while going around the down line and proceeding in the opposite direction.

The reference surface 20 has a first thermistor.
Temperature sensor 29 is provided. This temperature sensor 2
Reference numeral 9 detects the rail surface temperature (rail head temperature) when the reference surface 20 is pressed against the rail surface during measurement of the rail play distance. Further, a second temperature sensor 30 including a thermistor for detecting the atmospheric temperature is provided in the lower part of the apparatus body. This second temperature sensor 30
The atmospheric temperature detected by is sent to the host computer together with the rail clearance data as a reference value. When analyzing the rail clearance in the host computer, by referring to this atmospheric temperature, when the atmospheric temperature is higher than a certain temperature or is lower than a certain temperature,
The data on the rail clearance, etc. collected at that time are removed from the data for analysis.

The connector 3 is for connecting to a host computer (not shown), and after measuring a large number of rail clearances and temperatures, the device main body is connected to the host computer through the connector 3 to connect them. Upload the data of to the host computer. Also, when the data required for measurement is downloaded from the host computer to the apparatus body, the apparatus body is connected to the host computer by the connector 3.

FIG. 2 is a block diagram of a rail play distance measuring device.

The outputs of the temperature sensors 29 and 30 are input to the control unit 6 via the amplifier 4 and the A / D converter 5. Further, the displacement amount of the measurement block 1 is converted into displacement data by the displacement converter 7 and input to the control unit 6. Displacement converter 7
Is composed of, for example, a differential winding, a movable core that moves in the winding, and a circuit unit that detects the amount of movement of the movable core by the differential winding and converts this to displacement data. The measurement block 1 is connected to. The configuration of such a transition converter is known in the above-mentioned Japanese Utility Model Publication No. 7-18961.

The connector 3 is connected to the interface circuit 8, and the connector 3 and the interface circuit 8 are connected.
Data is uploaded (control unit 6 → host computer) and downloaded (host computer → control unit 6) between the control unit 6 and an upper host computer via.

The storage unit 9 stores a set number, the number of measurement points, a rail identification number, a measurement result and the like. The set number is a number for each management unit of the rail group that has been classified in advance, and is a set ID for identifying the rail group. The number of measurement points refers to the number of rail clearance positions to be measured included in each set number. The buzzer 10 emits a sound for confirmation to the operator when the enter key 22 is operated.
The arithmetic processing unit 11 is connected to the control unit 6 and performs various arithmetic operations.

Next, the operation of the rail clearance measuring device will be described.

FIG. 3 shows a procedure for measuring the rail clearance and the temperature using the rail clearance measuring device.

First, in step ST1, the rail clearance measuring device main body 2 is connected to the host computer 12 via the connector 3, and the set number, the number of measurement points, the measurement order, etc. are downloaded from the host computer 12. In the storage unit 9, the rail identification numbers included in the set number are arranged and stored by being downloaded. As shown in FIG. 4, the storage unit 9 stores, for each set number, a rail identification number, a rail clearance, a rail bottom temperature,
An area for storing the atmospheric temperature, the rail head temperature, and Δt is secured. The rail head temperature is the head temperature of the rail at the designated reference point in the rail group having one set number.
Δt is a value obtained by subtracting the rail bottom temperature from the rail head temperature at the designated reference point (in the example shown in the figure, Δt = 30−27 = 3 in the set number 1). This value is used when determining the rail bottom temperature at each measurement point, as described later. The rail identification number, the amount of rail clearance, the rail bottom temperature, and the atmospheric temperature have areas for storing only the number of measurement points. The rail identification numbers are usually arranged and stored in order from the smallest number. In the figure, in the set number 1, the first rail identification number is “00100”, and in the set number 2, the first rail identification number is “00600”. In FIG. 4, rail identification numbers and the like are shown only for the set numbers 1 and 2, but the same applies to the other set numbers.

When the measurer arrives at the site and turns on the power of the apparatus with the power key 25, the display shown in FIG. 5 (A) is displayed. In the figure, the numerical values 1 to 10 indicate the set numbers. The cursor key 27 is used to move the cursor to the position of the set number to be measured, and the enter key 22 is pressed (ST2). When the enter key 22 is pressed, the rail identification number of the first scheduled measurement location within the designated set number is displayed on the liquid crystal display 21 together with the arrow code indicating the measurement order. FIG. 5B shows a display example at this time. “00100” indicates a rail identification number. “00100” is the first measurement-scheduled rail identification number transmitted from the host computer.
As shown in FIG. 5, it is stored in the first area of the rail identification number storage area. Here, when the sequence key 28 is pressed, the measurement order is reversed, the n-th rail identification number of the final scheduled measurement point is displayed instead of the rail identification number of the first scheduled measurement point, and an arrow indicating the measurement order is displayed. The sign is displayed in the opposite direction. In the example shown in FIG. 4, when the sequence key 28 is pressed, "00200" is displayed as the rail identification number to be measured first. In FIG. 4, P indicates a pointer that points to the memory access area, and when the order key 28 is pressed once, “00100” to “0020”.
If you move to the area of "0" and press it again, "0010
The area of "0" is designated. Each time the sequence key 28 is operated, "00100" and "00200" are alternately designated. "00
When "100" is specified, "00101" → "00102" → "00103" in the subsequent measurement.
→ The pointer moves in the order of. This order is a predetermined order by the host computer, and here, this order is called a forward order. When "00200" is specified, "00200" is specified in the subsequent measurement.
The pointer moves in the order of “0” → “00199” → “00198” → ... Since this order moves in the opposite direction to the above normal order, it is referred to as a reverse order here. When the measurement order is normal, the rail identification numbers are sequentially displayed, and the rail bottom temperature obtained by the temperature sensor 29, the atmospheric temperature measured by the temperature sensor 30, and the rail clearance are displayed. The rail identification numbers are sequentially stored in the storage area corresponding to the displayed rail identification number, and when the measurement order set by the measurement order input means is in the reverse order, the rail identification numbers are sequentially displayed in the reverse order and measured by the temperature sensor 29. The rail bottom temperature, the atmospheric temperature measured by the temperature sensor 30, and the rail play distance thus obtained are sequentially stored in the storage area corresponding to the displayed rail identification number.

At the reference point, the rail head temperature t1 and the rail bottom temperature t2 are measured, and Δt
= T1-t2, Δt is obtained and stored. The rail bottom temperature t2 at each measurement point is t2 =
It is calculated by the rail head temperature t1−Δt. Difference between rail head temperature and rail bottom temperature at the reference point (Δt)
Is estimated to be substantially the same as the difference at other measurement points, so at each measurement point, only the rail head temperature t1 is measured, and Δt obtained at the reference point is subtracted from this value to determine the rail bottom portion. The temperature t2 is calculated. As a result, at each measuring point
The amount of rail play and the temperature at the bottom of the rail can be determined at the same time simply by pressing them once, reducing the burden on the operator.

The operation of the order key 28 is performed in ST3 of FIG.
It is valid only immediately after the set number is specified as shown in. Therefore, even if the sequence key 28 is operated during measurement, it is invalid.

When the rail identification number to be measured is designated and displayed in ST4, the process proceeds to the measurement subroutine in ST5. In the measurement subroutine, the measurement at the reference point and the measurement at each measurement point are performed in the rail group of all the set numbers.

The measurement result is displayed on the liquid crystal display 21, and when the current point is the reference point and the rail bottom temperature is detected, it is displayed as shown in FIG. 5C, and the current point is the reference point or the measurement point. When measuring the rail clearance, see Fig. 5.
It is displayed as shown in (D). The example shown in FIG. 5C indicates that the rail bottom temperature at the reference point is 25 ° C and the atmospheric temperature is 26 ° C. In the display example shown in FIG. 5D, the rail clearance is 9.5 mm, the rail head temperature is 27 ° C., and the atmospheric temperature is 26 ° C.

The data displayed as described above is stored in the storage unit 9 (ST6). Hereinafter, the above measurement is repeated until the measurement of the rail clearance and the temperature for all the rail identification numbers in the set number is completed, and when a plurality of set numbers are specified, each set number is also set. The above operation is repeated (ST7, ST8). When all the measurements are completed, the rail travel distance measuring apparatus main body 2 is connected to the host computer 12, and the set number, rail identification number, and measurement data stored in the storage unit 9 are uploaded to the host computer 12 (ST9). ). Figure 5
(E) is a display state during communication at this time.

FIG. 6 shows the measurement subroutine of ST5.

In ST10, if it is specified that the reference point is the reference point by operating the reference key 23 (if the current point is the reference point), the steps from ST11 onward are executed, and if not (current point). If is the measurement point)
Executes ST14 and thereafter.

When the reference point is designated, first,
The temperature t2 of the rail bottom is measured and stored in the storage unit 9.
In FIG. 7, the device main body 2 is pressed against the rail abdomen 13b,
The figure shows the state when the temperature t2 of the rail bottom portion 13c is being measured. The rail 13 includes a rail head 13a,
The cross section composed of the rail belly portion 13b and the rail bottom portion 13c is I.
The rail-shaped structure has a rail abdomen 13b and a rail bottom 1
Since it is considered that there is no temperature gradient of 3c, the apparatus main body 1
By pressing 0 against the rail abdomen 13b, the temperature t2 of the rail bottom 13c can be measured.

After the temperature t2 at the bottom of the rail is measured and stored in ST11, the apparatus main body 10 is pressed against the rail head to simultaneously measure the temperature t1 of the rail head and the rail clearance (ST12). FIG. 8 shows the state at this time. Set the measurement block 1 of the device body 10 to the rail clearance
To the rail head 13 by inserting the reference surface 20 of the apparatus main body 2 into the rail head 13
It is pressed against the side of a. As a result, the rail clearance 1
It is possible to simultaneously measure the temperature of the rail head 13a together with the play amount of 3d.

Subsequently, the temperature difference Δt between the rail head portion and the rail bottom portion is calculated by t1−t2 and stored in the storage unit 9.

Next, in the measurement at the measurement point, first in ST14, the apparatus main body is pressed against the rail clearance (state shown in FIG. 8) to simultaneously measure the rail head temperature t1 and the rail clearance. To do. Next, the temperature of the bottom of the rail is calculated by t1−Δt and stored in the storage unit 9 together with the rail clearance. At the same time, the atmospheric temperature at this time is also detected and stored by the temperature sensor 30. The display state at this time is as shown in FIG. In this way, the measurement data at the reference point and each measurement point are stored in the storage unit 9 one after another. FIG. 4 shows a state in which the measurement data at the reference point and the measurement point are stored for each rail group of set numbers 1 and 2.

Here, the pointer P indicates the access position to the storage area. When the reference point is designated, the pointer P moves to the reference point, and thereafter, for each measurement,
It moves sequentially toward the final measurement point corresponding to the set number. If the reference point of the rail group of set number 1 is designated for the rail identification number "00100", the pointer P is set at the position of the rail identification number "00100". As a result, the area designated by this pointer is set as the storage area for the data of the reference point. Therefore, as shown in the figure, the rail number "001
For “00”, that point is designated as a reference point, and the rail clearance, the rail bottom temperature t2, the atmospheric temperature, the rail head temperature t1, and Δt are stored. Δt
Is calculated as Δt = t1−t2 as described above.

When the measurement at the reference point is completed, the pointer P advances by one in the forward order, the next rail identification number "00101" is displayed on the liquid crystal display 21, and the measurement at this measurement point becomes possible. At the measurement point, the device main body is pressed against the rail head to measure the rail clearance and simultaneously measure the rail head temperature. The atmospheric temperature is also measured. Rail bottom temperature t2 is rail head temperature t1
Calculated by −Δt. Therefore, the storage unit 9 stores the rail clearance, the rail bottom temperature, and the atmospheric temperature corresponding to the rail identification number “00101”.

In this way, the measurement data is sequentially stored corresponding to each rail identification number. This order is a predetermined forward order, and the pointer P has a rail identification number of 1 Proceed as it increases. When the measurement at the last measurement point of the rail group of set number 1 is completed, and then the measurement of the rail group of set number 2 is started, the measurement is performed in the same order as the set number 1 in advance. When attempting to perform, the same measurement as above will be performed by returning to the point of the rail identification number "00500". Therefore, for example, if the group of rails with set number 1 is the up line and the group of rails with set number 2 is the down line, and if both of them are to be measured in the normal order, when the measurement of the up line is completed, After returning to (reference point), the down line measurement will be started. In FIG. 4, when the pointer P reaches “00200” and the measurement of the up line is completed, the pointer goes to “00500”, and this position is set as the reference point of the rail group of set number 2, and “00501” and “00502” are set. ... will proceed.

However, when the set number 2 is designated from "00200" and the reverse order is designated by the order key 28, the pointer P becomes "00600" and the rail identification number "00".
"600" can be designated as the reference point. FIG. 4 shows an example in which when the set number 2 is designated, the order key 28 is operated to designate the reverse order, and the point of the rail identification number “00600” is designated as the reference point. At this time, since the rail identification number "00600" corresponds to the position of the down line at the same position as the final measurement point of the up line, the measurer turns from the up line to the down line in the direction opposite to the up line (reverse order). You should continue to measure while proceeding to. Therefore,
For the set number 2, the pointer P uses the rail identification number “00600” as a reference point, and measures and stores the rail clearance, the rail bottom temperature, the atmospheric temperature, the rail head temperature, and Δt at this point. Then, "00599" →
The process proceeds in the reverse order of “00588” → “00587” → ..., and the measurement for the set number 2 ends at “00500”.

FIG. 9 shows rail identification numbers "00100" to.
It shows the flow line of the measurer when the up line of the set number 1 consisting of “00200” and the down line of the set number 2 consisting of the rail identification numbers “00500” to “00600” are the measurement targets. The first starting point is the rail identification number “00100” of the set number 1. If you select group number 1 at this point, "00100" will be displayed.
Then, by operating the reference key 23, "00100" is designated as the reference point. Next, the data at the reference point is measured and stored at "00100", and then "00101"
The measurement is performed while moving in the direction of arrow A in a normal order from, and the measurement at the measurement end point of "00200" is completed. Since the measurement for the set number 1 is completed at this stage, next,
Turn to the adjacent down line as indicated by arrow B and select the set number 2. At this time, "00500" is displayed, but by operating the order key 28, the display is changed to "00600".
Change to. Then, by operating the reference key 23, "006
00 "is designated as the reference point. The measurement order is now reversed. Next, the data of the reference point is measured and stored at “00600”, and thereafter, the measurement is performed while moving in the reverse direction from “00600” in the direction of arrow C, and “005
The measurement at the measurement end point of "00" is completed. At this stage, the measurement for the set number 2 is finished, and all the measurements are finished.

As shown in FIG. 4, when performing the above-described measurement, the pointer P moves in the direction opposite to that in the up-line measurement during the down-line measurement.

In the above measurement example, the measurement is started from "00100" of the set number 1. However, when the measurer is first at the point "00200", the sequence key 28 is selected immediately after selecting the set number 1. By operating, the measurement can be started in reverse order with "00200" as the reference point for the upstream line. In this case, “00100” is the measurement end point of the set number 1, so at that point, the operation of the set number 2 → the normal order selection by the order key 28 → the reference key 23
The operation is performed, and the measurement is started in the normal order with "00500" as the reference point for the down line.

FIG. 10 shows the flow line of the measurer when the group of rails with set numbers 1 to 4 is the measurement target. In this example,
The rail groups of set numbers 1 and 2 are continuous in the up line, and the rail groups of set numbers 3 and 4 are continuous in the down line. The circles in the figure indicate the reference points of the rail group of each set number. Set number 1
For the rail groups of 2 and 2, the measurement is performed in the normal order, and for the rail groups of set numbers 3 and 4, the measurement is performed in the reverse order. The measurer moves in the order of A → B → C → D → E. Therefore, all the measurements can be completed with the most efficient movement.

According to the present invention, the measurement order can be arbitrarily set in the forward order or the reverse order. If the set order is normal order, the rail identification number will be displayed sequentially in a predetermined direction,
If the reverse order is set, the rail identification numbers are sequentially displayed in the direction opposite to the predetermined direction. According to this, for example, when performing the measurement of the up line and the down line, after measuring up to the measurement end point of the up line in the up line, set the measurement order in reverse order, reverse the down line from that position. Since it is possible to proceed in the direction and perform the measurement, it is possible to perform the measurement of the up line and the down line in one round trip. Therefore, not only the measurement of the up line and the down line, but also the measurement of the complicated line,
By properly setting the forward order and the reverse order, the burden on the measurer can be reduced, the time required for the measurement can be shortened, and the efficiency can be improved.
