JP5823823B2 - Method and apparatus for managing lock state of electric switch - Google Patents

Description

  The present invention relates to a method for managing the lock state of an electric switch and an apparatus for using the method.

  There is an electric switch (hereinafter simply referred to as a switch) at a point where a train (or vehicle, hereinafter the same) is moved from one track to another, that is, at a branch point of the railway track. is set up. The switching machine includes a conversion device that converts the Tongrel to close contact with the basic rail, or separates the Tongrel from the basic rail, and a locking device that holds the close or separated Tongrel in its position. .

  The conversion device has an operating mechanism connected to the tongrel to convert the tongrel, and the locking device has a locking device connected to the tongrel to hold the tightly or spaced tongrel in its position. And a lock piece that fits into the notch of the lock and locks in place. Then, by inserting the lock piece from the side into the notch of the locking cane interlocked with the tongrel, the state where the movement of the tongrel is prevented, that is, the locked state of the locking cane and the lock piece is completed.

  When the train passes through the point, it is necessary that the tip of the Tongleil is in close contact with the basic rail and is completely locked so that it does not open. Ideally, there should be no gap between the lock cane and the lock piece, but there may be a gap between the lock cane and the lock piece due to the slight movement of the lock cane. Since the lock piece is caught by the lock and cannot be changed, the train cannot be operated.

  As described above, it is desirable that the separation width (opening amount) of the Tongleil from the basic rail in the close contact state is 0, but it is considered safe from the rule of thumb up to 5 mm. Generally, the width of the lock piece is 40 mm with respect to the notch width of 43 mm of the lock can, and the distance between the notch of the lock can and the lock piece is 3 mm in total on both sides. This is based on the assumption that the allowable wear amount of the notch and the lock piece of the lock cane is 1 mm, and the margin amount such as wear of the jaw pin is 1 mm.

  The center position of the notch of the lock can shift from the reference position (the center of the width of the lock piece) due to the notch of the lock cane, wear of the lock piece or jaw pin, etc., and the amount of displacement exceeds the specified value Since it is necessary to adjust the amount of displacement of the lock before the lock is disabled, the lock status is regularly managed.

The conventional first lock state management method is a method of managing only by visual confirmation, forcibly driving the turning machine to move the tongrel to the localization side and the opposite side, and When the lock status confirmation window is opened and the amount of displacement from the reference position of the locking cane on each of the localization side and the reverse side is visually confirmed, and it is determined that the displacement exceeds the specified value, The amount of displacement is adjusted within a specified value by adjusting the mounting state of the lock or grinding the lock piece.

  Also, the second conventional lock state management method is to forcibly drive the tipping machine to move the tongler to the fixed side and the reverse side, and directly measure the displacement amount using a ruler such as an insertion gauge. It is a method of measuring.

  In addition, as a conventional third lock state management method, a method of photographing a lock state with a camera from a lock state confirmation window is also described in Patent Document 1, but an image obtained by photographing is a lock lock canister. It is used to estimate the amount of displacement from the reference position and determine whether or not the amount of displacement needs to be adjusted.

  Furthermore, as a conventional fourth lock state management method, Patent Document 2 uses a lock displacement amount detector and sets the distance between the lock cane line and the gauge line as the lock displacement amount when the lock is completed. Is described.

JP 2009-298302 A JP 2010-215044 A

  Since the first conventional method is managed only by visual confirmation, there is a problem that the reliability of the displacement measurement is low, the management cannot be handled as a numerical value, and therefore a history cannot be left. . Since the second conventional method uses an insertion gauge or the like, there is a high possibility that a measurement error or the like will occur. Therefore, there is a problem that the objectivity of the data is not guaranteed and the measurement work is dangerous. The third conventional method of photographing the locked state with the camera can leave a history, but the image in the locked state may be unclear, and there is a problem that the measurement accuracy of the displacement amount from the image is low. . In the fourth conventional method using the lock displacement amount detector, the lock displacement amount output from the lock displacement amount detector represents the difference between the displacement amounts on the left and right sides from the reference position of the lock cane. There is a problem that it is difficult to perform the adjustment accurately according to the amount of displacement on both the left and right sides. In any of the above conventional methods, it is difficult to control a large number of turning machines, and the reliability of measuring the displacement amount of the lock cane is low. It cannot be used for the management plan of the lock state.

  The present invention has been made in view of the above problems, and is a lock state management method capable of automating the management of the lock state, accurately measuring the amount of displacement from the reference position of the lock cane, and managing the correct data numerically. And it aims at providing the lock state management apparatus which uses the method.

In order to achieve the above object, the lock state management method according to the present invention includes the following steps (claim 1).
(1) Using a photographing device , photograph at least the part where the management number of the turning machine is written (hereinafter referred to as the management number written part) and the locked state at the installation site of the turning machine, In this case, after the clerk adjusts the amount of displacement of the lock mechanism of the switch, the first step of photographing the lock state of the switch again using the photographing device .
(2) A second step in which the image processing apparatus captures an image photographed by the photographing apparatus and stores it in the storage means.
(3) A third step in which the image processing apparatus performs the following processing in the following order on the image stored in the storage unit.
Specifying a folder to specify the location of the point lock unit group of images (A) station units, and stores the image into the folder process.
(B) the process of selecting the best set out of the image and the locked state image management number according portion of the plurality of sets stored in the folder for the same one point lock unit as the best shot image.
(C) selected best shot management number according moiety from taking read the management number of the point lock device processing of the image.
(D) selected best shot process of measurement from the locked state image displacement amount of locking cans image.
(E) the displacement of the locking cans were measured and management number of the point lock device read and converted into text data, creates management data list corresponding to the image of the predetermined folder storing and / or Processing to output via output means.

In photographing by the photographing device, it is desirable to photograph the locked state when the locking cane is locked on the fixed side and the locked state when the locking cane is locked on the opposite side (claim 2).

The second step of capturing an image captured by the image capturing device using the image capturing unit and storing the image in the storage unit may be performed by capturing the image of the image capturing device via a wireless or wired communication unit. 3).

Instead of the process of reading the management number of the machine from the image by the machine management number reading means, a process of manually entering the management number can be performed.

The process of measuring the displacement amount of the lock cane from the lock state image by the lock cane displacement measuring means is based on the displacement of the lock piece width on the image with respect to the number of pixels on the basis of the lock piece width, for example, 40 mm. The amount of displacement is measured based on the number of pixels of the quantity (claim 5). Further, the measurement of the displacement amount of the lock cane is characterized by measuring the displacement amounts on both the left and right sides of the lock piece (claim 6).

According to a preferred embodiment of the present invention, in the third step of the invention of claim 1, the trend graph of the displacement amount of the lock cane of each switch based on the output text data, that is, time series A process of creating and outputting a graph showing a trend by a trend graph creating means is added (claim 7).

The lock status management method locked state management device for use has a photographing unit for photographing a management number according moiety and the locked state of the point lock unit, and an image processing apparatus, image processing apparatus, imaging apparatus The image capturing unit that captures the image captured by the storage unit and stores the image in the storage unit, and a folder for designating the storage location of the image of the switching machine group for each station is specified for the image stored in the storage unit. And the folder specifying means for storing the image in the folder, and the best set of the images in the management number description part and the lock state image stored in the folder for the same switch as the best shot image Best shot image selection means to be selected, and switch management number reading means for reading the management number of the switch from the management number description portion of the selected best shot image The lock-can displacement measuring means for measuring the displacement of the lock cane from the lock state image of the selected best shot image, the control number of the turning machine read and the measured displacement of the lock cane Management data creating means for converting to text data and creating and storing a management data list corresponding to an image in a predetermined folder, and output means for outputting the created management data list (claim 8).

According to the first aspect of the present invention, after adjusting the amount of displacement of the lock cane, the locking state of the switch is again photographed by the photographing device , so that the field work is simple, so a measurement error occurs. There is nothing. In addition, since the amount of displacement of the lock cane is measured by image processing of the image and management is performed using text data, it is possible to automate the lock state management and manage numerical values of correct data. Furthermore, since the measurement data of the displacement amount and the locked image can be viewed simultaneously, the correctness of the measurement data can be guaranteed to a third party. Furthermore, the past history such as the locked state in the past several years can be confirmed as an accurate numerical value.

  According to the second aspect of the present invention, since the locked state on the localization side and the inverted side can be compared and confirmed while comparing the measured values, it is easy to find the difference when there is a difference in the amount of displacement. It contributes to the investigation of the cause.

According to the invention of claim 5, the amount of displacement from the reference position of the lock can be accurately measured, and the amount of displacement is based on the same reference even if the photographing distance and viewing angle of the photographing device are different. Can be easily measured.
According to the sixth aspect of the present invention, the displacement amount on both sides of the lock piece is measured and output, and the displacement amount on both sides can be known, so that the operator can easily perform the displacement amount adjusting operation.

In the conventional lock state management method, it is difficult to browse past information. However, according to the invention according to claim 7 , since past information can be displayed in a graph and history management can be performed, a trend can be learned from the graph. This makes it easier to make maintenance plans for turning machines.

According to the eighth aspect of the present invention, a digital camera, a digital video camera, a mobile phone, and other commercially available photographing devices such as a camera incorporated in a portable electronic device, and a computer having image processing software are used. Since the system which implements the lock state management method according to the invention can be configured, an inexpensive lock state management device can be provided.

Next, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the lock state management method according to the embodiment of the present invention includes at least a part (management number description part) in which a management number of the turning machine is written at the installation site of the turning machine and a lock. Take a picture of the state with a photographing device , visually check the lock state to be photographed to determine whether or not it is necessary to adjust the amount of displacement of the lock, and if necessary, adjust the amount of displacement of the lock Again, a first step of photographing the lock state of the switch with the photographing device , a second step of capturing an image of the photographing device into the storage means of the image processing device, and an image captured in the storage means And a third step of performing predetermined image processing. Below, each process is explained in full detail.

[First step]
In the first step, the image of the tipper is photographed using a photographing device (1 in FIG. 6). The photographing apparatus 1 is a commercially available image that can form an image of a format that can be taken into the image processing apparatus 100 as will be described later, such as a digital camera, a digital video camera, or a camera built in a mobile phone. If it is a camera, there is no limitation.

  The object to be photographed is all the turning machines in the station premises to be managed in the locked state. First, in order to identify the turning machine, as shown in FIG. Preferably, the entire image of the switch A installed in the camera is photographed, for example, a range indicated by an ellipse B1 in FIG. 2, or at least a portion where the management number N is recorded, and then a memory card or other recording medium Save to. From the standpoint of facilitating accurate reading of the management number N, which will be described later, it is preferable to take a picture from directly above the switch A, but if the management number can be read, the picture can be taken from diagonally above. I do not care.

The management number N (51 in the example of FIG. 2) of the switching machine A is organized into numbers that can be identified for each station that is a management unit. In this way, it can be seen from the management number N that is captured in the image of the turning machine A that the number of the turning machine images.

Next, the lock state confirmation window W (FIG. 2) of the turning machine A is opened, and the lock state that is visible, that is, the lock piece is fitted into the notch of the lock canister, is further detailed. Shoots the width of the lock piece and the gaps on both sides, that is, the amount of displacement of the lock. The amount of displacement of the lock canister is determined by operating the controller provided in the switch body 1 and moving the Tongleil to the normal position and the displacement amount when moving the reverse position. And save them on the same recording medium. The operation of the controller may be either a manual operation performed directly on the site by selecting a time zone during which the train does not pass, or a remote operation in which a control signal is transmitted from a signal handling station.

Here, the locked state of the turning machine will be described with reference to FIGS.
In FIG. 2, reference numeral 1 is a switch body, 2 is a motor attached to one end of the switch machine body, 3 is an operation mechanism driven by the motor 2, and is adjusted by an adjuster rod 4. Connected to R2. Reference numeral 5 denotes a lock cane, which is connected to the Tongrel R2 via a connecting can 6. R1 is a basic rail.

As is well known, a friction clutch, an intermediate gear, and a conversion gear (all not shown) are provided in the switch machine body 1 as a power transmission system of the motor, and are further shown in FIG. A known conversion device 7 and locking device 8 are provided.

  The conversion device 7 has a conversion roller 9 erected on the conversion gear and a horizontal penetrating from one side of the switch machine body 1 to the other side, and cams in the central part existing in the switch machine body 1 It consists of an operating can 3 having a groove 10. The cam groove 10 has an escape cam surface in the vicinity of the opening and a conversion cam surface in the back. When the motor 2 rotates in a predetermined direction or in the opposite direction, the conversion roller 9 escapes the escape cam surface of the cam groove 10 of the operation lever 3. And the contact with the conversion cam surface, the operating can 3 is moved forward or backward in the longitudinal direction, and as a result, the tongrel R2 is converted to a point orientation in close contact with the basic rail R1, or is separated from the basic rail. It has been converted to a place.

  The locking device 8 is connected to a pair of cam bars 11a and 11b slidably arranged in a horizontal direction perpendicular to the longitudinal direction of the operation cannula 3 below the operation cannula 3, and to the other end of each cam bar. It consists of a pair of lock pieces 12a, 12b extending in the sliding direction and the lock can 5. The lock can is provided with a pair of upper and lower 5a and 5b. The pair of cam bars 11a and 11b have an escape cam surface that contacts the conversion roller 9 and a conversion cam surface at the back, and the pair of lock pieces 12a and 12b are elongated by the rotation of the conversion roller in a predetermined direction or in the opposite direction. It is configured to move forward or backward in the direction. As shown in FIG. 4, the pair of lock pieces 12a and 12b are provided with locking blocks 13a and 13b, one of which protrudes upward and the other of which protrudes downward, as shown in FIG. The pair of upper and lower locking canisters 5a and 5b are coupled with a predetermined distance, and open downward to the upper locking canister 5a at a position spaced a predetermined distance in the longitudinal direction on the opposing surface. A notch 14b is formed in the lower lock can 5b.

With the above configuration, when a train is operated, the motor 2 rotates in a predetermined direction when a command is given from the signal handling station to the controller of the machine A to change the point from inversion to localization. First, the conversion device 7 is operated, and the operation cannula 3 brings the tongue rail R2 into close contact with the basic rail R1, so that the point is changed from the inverted position to the fixed position. When the conversion is completed, the locking device 8 is operated by the continuous rotation of the motor 2 in the predetermined direction, and the locking block of the predetermined one lock piece is fitted into the notch of the predetermined one locking pin. The state is locked. Also, when a command to change from the normal position to the reverse position is given from the signal handling place, the motor 2 rotates in the opposite direction, the conversion device 7 operates first, and the operation can 3 moves the Tongleil R2 to the basic rail. In order to move away from R1, the point is changed from stereo to inversion. When the conversion is completed, the locking device 8 is operated by the continuous rotation of the motor 2 in the opposite direction, and the locking block of the predetermined other lock piece is fitted into the notch of the predetermined other locking rod. The position status is locked.

That is, when point localization is locking block 13b on the left side of the lock piece 12b of FIG. 3 is retracted from the moving surface of the locking cans 5b of the lower moving forward, locking block on the right side of the lock piece 12a Since 13a moves backward and fits into the notch 14a of the upper locking cane 5a, the localization state is locked. Further, at the time of point inversion, the lock block 13a of the right lock piece 12a in FIG. 3 moves forward and retreats from the moving surface of the upper lock can 5a, but the left lock piece 12b moves backward to lock the lock. Since the block 13b fits into the notch 14b of the lower lock can 5b, the inverted position is locked.

  And when implementing the method of this invention, the said controller is operated manually or remotely, a tipping machine is changed into a localization side and an inversion side, and the lock state in each case is image | photographed. The switch A is provided with a lock state confirmation window W, and when the window is opened, a portion indicated by a circle B2 in FIG. 3 can be seen.

  It is desirable that the camera at the time of shooting is installed at a predetermined distance from the window W and the zoom rate is the same in any of the turning machines, since the subsequent image processing becomes easy. . However, even if the shooting distance and the shooting angle are slightly different, there will be no problem if the processing for matching the width of the lock piece as a standard is performed in the image processing as will be described later. Also, it is difficult to form a complete image at one time. Therefore, it is desirable to photograph one subject at least twice.

  FIG. 5A shows an image P in a locked state taken with the window W opened.

In the first step, the locked state viewed from the confirmation window W or the captured image is reproduced on the camera, and for example, the locked state shown in FIG. Whether or not the displacement amount needs to be adjusted is determined based on the magnitude relationship between the gaps 15R and 15L between the left and right sides of the notch 14a of 5a, that is, whether or not the displacement amount of the lock can 5a is equal to or greater than a specified value. If not, the process proceeds to the second step, but if necessary, the center of the notch 14a of the lock cane is positioned at the center in the width direction of the lock piece 12a using a conventional adjustment mechanism. In other words, the mounting position of the lock can 5a is adjusted so that the dimensions of the gaps 15R, 15L on the left and right sides of the left and right lock pieces are equal.
The determination of the necessity of displacement amount adjustment and the displacement amount adjustment work when necessary are performed for both localization and inversion. Then, after each adjustment operation is completed, the locked window is shot again from the confirmation window W.

[Second step]
When the photographing of all the switching machines to be managed by the photographing apparatus 1 is completed, as a second step, the image stored in the photographing apparatus is captured into the image processing apparatus 100 using the image capturing means, The image is stored in the storage unit of the image processing apparatus 100. The image processing apparatus 100 performs predetermined image processing using known software, as will be described later with reference to FIGS. Image capturing by the image capturing means is performed by taking out a memory card from the camera and inserting it into a card slot provided in the input unit 105 of the image processing apparatus 100, or connecting the camera to the input unit 105 with a USB code from a recording medium. Any method can be used, such as capturing an image, or transmitting an image from a portable electronic device via the Internet or by transmitting to the communication unit 107 by other wired or wireless communication means.

[Third step]
The image captured by the image capturing means is subjected to predetermined image processing by the image processing apparatus 100 configured by a computer illustrated in FIG. 6 as a third step. The image processing apparatus 100 includes a CPU (central processing unit) 101, a storage unit 103 and an IO interface 104 connected to the CPU 101 via a data bus 102, an input unit 105 connected to the interface, an output unit, For example, the display unit 106 and the communication unit 107 are included.

The input unit 105 is also used when capturing an image from a camera memory card or other recording medium. The communication unit 107 is used when capturing an image from an imaging device having a communication function via the Internet or wireless communication. Therefore, the input unit 105 and the communication unit 107 constitute a part of the image capturing unit.

  As shown in FIG. 7, the CPU 101 is a folder specifying unit 101a, a best shot image selecting unit 101b, an image managing unit 101c, a switch machine management, as exemplified in FIG. It has number reading means 101d, lock-clamp displacement measuring means 101e, management data creation means 101f, trend graph creation means 101g, and output means 101h. Subsequently, each means will be described.

Based on the input from the input unit 105, the folder designating unit 101a is for designating the storage location of the station group image stored in the buffer memory of the storage unit 103, which is taken from the photographing apparatus . A folder is specified, and the image is stored in the folder so that it can be managed.

The stored image may have out-of-focus, lightness, and saturation. The best shot image selection unit 101b measures the focus, brightness, saturation, and the like of a plurality of images of the same subject, and displays the best one on the display unit 106 as the best shot image based on the measurement result. Photographer, can be selected by operating the input unit 105 that appears as a best shot image. Thereby, the reliability of the measurement result by the post-locking lock displacement measuring means 101e can be improved. When one best shot image is selected, only that image is saved and the rest are erased.

  The image management means 101c groups the images remaining after selection / erasure by the best shot image selection means 101b into one group for each turning machine, that is, the whole image of the turning machine and the localization and inversion locked states. One set of images is stored in a predetermined storage area of the storage unit 103 to manage the images.

  The switch machine management number reading means 101d is composed of a well-known OCR (optical character reader), and based on the command input from the input unit, the switch machine management number reading means 101d is transferred from the entire image of the switch machine. The machine management number is read. Instead of reading the management number by OCR, a method of manually entering the management number into the computer by operating the input unit, or a method of reading an ID tag, QR code (registered trademark) or bar code representing the management number of the switch Good.

The lock-can displacement measuring means 101e measures the displacement of the lock from the locked images in each set of images according to the following procedure. That is, the width of the lock piece in the image and the gaps 15R and 15L existing on both the right and left sides of the lock piece are measured, the ratio of the measured value to the reference value of the width of the lock piece is obtained, and the ratio is the measured value of the gap. To find the actual value of each gap. That is, regardless of the width dimension in the image of the lock piece, it is assumed that it is an actual dimension, and the dimension of the gap when this is used as a reference is calculated. The reference value of the width of the lock piece is defined as 40.00 mm.

  The management data creation means 101f includes a management number read by the switch machine management number reading means 101d, and a measured value of the width of the lock piece and the clearance between the left and right sides of the lock piece obtained by the lock-claw displacement measuring means 101e. Is converted into text data, a management data list corresponding to each set of images in a predetermined folder is created and stored in the storage area.

  Further, in order to make the width and the gaps 15R and 15L of the lock piece (13a) of the image in the previous locked state easier to see, different colors or patterns are added as shown in FIG. It is desirable to form and save a composite image by overwriting 40.00 mm, 1.53 mm, and 2.10 mm.

  In this way, since the measured values of the width of the lock piece and the gaps on the left and right sides are expressed numerically in the actual image, the displacement amount can be recognized more accurately than in the case where only the image is visually confirmed, and numerical management is possible. It is possible to prevent measurement errors and illusions.

  FIG. 8 shows an example of a management data list (MDL) stored for the switch having the management number 51. The symbol “O” in the evaluation column on the right side of each measured value means that the value is within the reference value, and the symbol “x” means that the value exceeds the reference value. The type of the symbol is arbitrary if it can be identified. For example, the reference value may be displayed in green and the reference value exceeding red may be displayed in red. It is also desirable to record the reliability of each image, that is, the degree of focus.

  The management data can be displayed on the display unit 106 by a command input from the input unit 105. And when the symbol indicating the reference value exceeds is displayed in the evaluation column on the right side of any measured value, it is possible to easily know that the displacement amount adjustment is necessary for the switch. .

  When the displacement adjustment work is performed based on the necessity, the second shooting is performed after that, so the first shooting is included in the management data list (MDL) of FIG. The management data corresponding to the second shooting is recorded below the management data corresponding to.

  The output unit 101h reads and displays predetermined information, for example, a specified image and specified management data, based on a command input from the input unit 103 among various types of information stored in the storage unit 103. To do. A printer may be added to the output unit 101h.

  The above-mentioned shooting in the locked state of the switch is performed at a frequency of once a month, once every three months, or once a year, depending on the environmental conditions of the railway track. Therefore, in a preferred embodiment of the present invention, the past history (image data and management data) is stored in the storage unit 103 of the computer while the switch is being used. Then, the CPU 101 is provided with a trend graph creating means 101g, and based on a command input from the input unit 103, a past history is read for the designated switch and a trend graph as illustrated in FIG. 9 is created. I can do it.

  FIG. 9 is a trend graph with the displacement (mm) on the vertical axis and the time (t) on the horizontal axis. The displacement on the right side is positive with respect to the reference position (displacement amount 0). Is represented by a minus sign. FIG. 9 shows that the lock gradually shifts to the right side and the displacement amount was adjusted during the fourth inspection. In this way, by looking at the trend graph, the tendency of the turning machine to go wrong can be understood, so it is easy to make a management plan for the turning machine.
