Description

  The present invention relates to a control section length measuring system, a control section length measuring method, and a program for a level crossing controller.

  Conventionally, a railroad crossing control device that operates a railroad crossing device such as a railroad crossing breaker and a railroad crossing alarm when a train passes through a railroad crossing is used. This level crossing control device controls, for example, a level crossing device according to a detection signal that is output when a set of level crossing controllers arranged at both ends of a closed section across a level crossing detects a train. . Each level crossing controller has a train detection range (hereinafter referred to as “train detection range”). More specifically, the level crossing control device starts a level crossing alarm according to a detection signal output when a train enters the train detection range of a level crossing controller arranged at the start position of the block section. Control is performed to end a level crossing alarm in accordance with a detection signal output when a train advances from a train detection range of a level crossing controller arranged at the end point of the section.

  A railroad crossing controller that detects the entry or advancing of a train is usually composed of a short track circuit using rails. When the train is within the train detection range of the railroad crossing controller, the railroad crossing is controlled by the train axle. Using the phenomenon that the track circuit of the controller is short-circuited, it detects the entry of a train into or out of the train detection range, and detects a signal indicating the detected state of this train Output as a signal. More specifically, for example, when the train enters the train detection range of the railroad crossing controller and the track circuit is short-circuited, the relay is operated (for example, the relay contact is dropped to indicate that the rail is short-circuited) To work). Also, when the train advances from within the train detection range of the railroad crossing controller and the short circuit of the track circuit is released, the relay is operated in the reverse state (for example, the state that the relay is raised and the rail is not short-circuited) To work). The railroad crossing controller outputs a signal indicating the operation of the relay as described above as a train detection signal (see Patent Document 1).

  The distance indicating the width of the train detection range of the railroad crossing controller (hereinafter referred to as “control section length”) is set to a distance of 30 [m], for example. If it falls, the control section length will become short and it will become difficult to detect a train. Therefore, in order to prevent a malfunction of the railroad crossing control device due to a decrease in the detection performance of the train by the railroad crossing controller, it is necessary to periodically measure the control section length of the railroad crossing controller.

  For this reason, conventionally, the operator uses a track short circuit that short-circuits the track circuit by short-circuiting the two rails, and the train axle is short-circuited to the track circuit of the crossing controller. A level crossing control is performed by creating a state and checking the operation of the level crossing controller while moving a predetermined distance, for example, 1 [m], at a place where the two rails are short-circuited using the track short circuit. The control interval length of the child was measured. In addition, the measurer visually checks the train that is actually operating and measures the control section length of the crossing controller.

  In addition, a method is disclosed in which an electric inspection vehicle, which is a vehicle dedicated to inspection, is run on a route to be measured and the control section length of a level crossing controller is measured (see Patent Document 2).

  However, in the method of measuring the control section length of the level crossing controller by visually confirming the train that is actually operating, the measurement is performed by the measurer's visual measurement, so the control section length is accurately measured. There was a problem that could not be done.

  Also, in the method of measuring the control section length of the railroad crossing controller using a track short circuit, the short circuit state between the two rails differs depending on the skill of the measurer, so the short circuit state cannot be made uniform. The reliability of the measurement data will be low. Moreover, in the measurement of the control section length by the track short circuit, in order to confirm by actually operating the crossing controller, a train detection signal is output from the crossing controller along with the measurement of the control section length. The level crossing control device operates in response to the detection signal, and an unnecessary level crossing alarm is issued. In addition, since the measurer enters the train tracks and performs measurements, it is necessary to take measures such as stopping the train operation to prevent a train accident or working at night when the train is not operating. There was a problem that the measurement work became complicated as the number increased.

  In addition, even when measuring the control section length of a railroad crossing controller using an electric inspection vehicle, in order to operate the electric inspection vehicle, if the measurement is performed during normal train operation, the train operation There was a problem that it was necessary to take measures such as changing the time, which would affect normal train operation.

  The present invention has been made on the basis of the above-mentioned problem recognition, and does not affect the operation of other devices or normal trains, and there is no variation in measurement results by the measurer, and the control of the crossing controller It is an object of the present invention to provide a control section length measurement system, a control section length measurement method, and a program for a crossing controller that can measure a section length.

It is the figure which showed an example of the control area length measured in the control area length measurement system of embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a control section length measurement system according to an embodiment of the present invention. In FIG. 1, the control section length measurement system includes a relay operation detection unit 10, a time measurement unit 20, a vehicle speed measurement unit 30, and a control section calculation unit 40. The time measuring unit 20 is connected to a measuring time display unit 21 and a crossing controller type switching unit 22. In addition, the measurement time display unit 21 and the crossing controller type switching unit 22 can be configured to be provided in the time control side unit 20.

  Note that there are a crossing controller of the HC (closed circuit) type and a crossing controller of the HO (open circuit) type as a crossing controller which is a measurement object for measuring the control section length. The HC type railroad crossing controller always keeps the relay in a state indicating that the rail is short-circuited (hereinafter referred to as “ON state”), and there is a train within the train detection range of the crossing control The relay state is changed to a state (hereinafter referred to as “OFF state”) indicating that the rail is not short-circuited. The HO-type railroad crossing controller always keeps the relay in the OFF state, and turns the relay on when the train is within the train detection range of the railroad crossing controller. In the control section length measurement system of the present embodiment, the level crossing controller type switching unit 22 determines whether the level crossing controller to be measured is an HC type crossing controller or a HO type crossing control according to the setting of the measurer. Switch whether it is a child.

  In the description of the present embodiment, it is assumed that the crossing controller that is the measurement target is a HO type crossing controller. In addition, when this embodiment is applied to an HC-type railroad crossing controller, it can be applied by replacing the ON state and OFF state of the relay with opposite states.

  The relay operation detection unit 10 detects the operation state of the relay of the crossing controller that is a measurement target for measuring the control section length. Further, the relay operation detection unit 10 outputs a relay operation detection signal indicating whether the relay of the level crossing controller to be measured is in an ON state or an OFF state to the time measurement unit 20.

  The level crossing controller that is a measurement target in the present embodiment displays, for example, an LED (Light Emitting Diode) indicating whether the relay of the level crossing controller is in an ON state or an OFF state. A lamp (hereinafter referred to as “relay operation display lamp”) is provided. The relay operation detection unit 10 detects that the relay operation indicator lamp is turned on (for example, the relay indicates an ON state) and extinguished (for example, the relay indicates an OFF state). Or an OFF state, and a relay operation detection signal is output according to the detected relay state. For example, the relay operation detection signal outputs a “High” level signal when the relay indicates an ON state, and outputs a “Low” level signal when the relay indicates an OFF state.

  In the present invention, the method for detecting the operation state of the relay of the crossing controller performed by the relay operation detection unit 10 is not limited to the configuration of the present embodiment, and whether the relay of the crossing controller is in an ON state, Any configuration that can detect whether it is in the OFF state can be changed to various configurations. For example, if the level crossing controller to be measured does not have a relay operation indicator lamp, use a current sensor that detects the current of the signal line that indicates the ON state and OFF state of the relay connected to the relay. It can also be configured to detect whether the relay of the controller is in an ON state or an OFF state and output a relay operation detection signal according to the detected relay state.

The level crossing controller type switching unit 22 switches the setting as to whether the level crossing controller to be measured is an HC type crossing controller or a HO type crossing controller in accordance with the setting of the measurer. The level crossing controller type switching unit 22 includes, for example, a switch. Moreover, the level crossing controller type switching unit 22 may be configured to include a display unit that indicates which type of the level crossing controller to be measured is set.
In the present invention, there is no limitation on the method of switching the level crossing controller type by the level crossing controller type switching unit 22.

Based on the setting of the level crossing controller type switching unit 22, the time measuring unit 20 is in a state where a train exists within the train detection range of the level crossing controller based on the relay operation detection signal input from the relay operation detecting unit 10. Determine. Moreover, the time measurement part 20 measures the time which has shown the state in which the train exists in the train detection range of a level crossing controller based on the relay action detection signal input from the relay action detection part 10. FIG. For example, when the level crossing controller to be measured is set as the HO type crossing controller by the level crossing controller type switching unit 22, the relay operation detection signal input from the relay operation detection unit 10 is “High”. “Measure the time that is level. In addition, the time measurement unit 20 outputs data representing the measured time (hereinafter referred to as “train detection time”) to the control section calculation unit 40.
In addition, the time measurement unit 20 outputs the train detection time to the measurement time display unit 21 and causes the measurement time display unit 21 to display the measured time.

  The measurement time display unit 21 displays the train detection time input from the time measurement unit 20. In addition, in this invention, there is no limitation regarding the display method of the train detection time by the measurement time display part 21. FIG. For example, the measurement time display unit 21 may be configured by a plurality of 7-segment LEDs, and a value (time) corresponding to the train detection time input from the time measurement unit 20 may be displayed. In addition, for example, a value (time) corresponding to the train detection time input from the time measurement unit 20 can be displayed on an LCD (Liquid Crystal Display).

The vehicle speed measurement unit 30 measures the speed of the train within the train detection range of the crossing controller that is the measurement target. Further, the vehicle speed measuring unit 30 outputs data representing the measured train speed (hereinafter referred to as “train speed”) to the control section calculating unit 40.
For the vehicle speed measurement unit 30 in the present embodiment, a speed measuring instrument such as a speed gun, for example, that measures the speed of the moving object is used.

  The control section calculation unit 40 is input from the train detection time input from the time measurement unit 20 and the vehicle speed measurement unit 30. Based on the train speed thus obtained, the control section length of the level crossing controller that is the measurement target is calculated. The train data input in advance and the method for calculating the control section length will be described later. The control section calculation unit 40 outputs the calculation result of the control section length to a display device or storage device (not shown).

  Next, a measurement method in the control section length measurement system of this embodiment will be described. FIG. 2 is a diagram for explaining a method of measuring the control section length in the control section length measurement system of the present embodiment. FIG. 2 shows a measurement method when a train enters from the right side of the figure, passes in front of the level crossing controller, and advances to the left side of the figure. FIG. 2 shows a case where two vehicle speed measuring units 30 (vehicle speed measuring units 30-1 and 30-2) are provided.

  First, before the train enters the train detection range (= control section length) of the railroad crossing controller, preparation for measurement is performed by the control section length measurement system of the present embodiment. More specifically, as shown in FIG. 2A, the relay operation detection unit 10 is arranged at a position where the lighting and extinguishing of the relay operation display lamp of the crossing controller that is the measurement target can be detected. In addition, the vehicle speed measuring unit 30-1 measures the speed of the train that advances from the train detection range to the position where the speed of the train entering the train detection range can be measured. Place them in the possible positions. In addition, data of a train that enters the train detection range of the crossing controller that is the measurement target is input to the control section calculation unit 40. Further, the crossing controller type switching unit 22 switches the form of the crossing controller to a form suitable for the type of the crossing controller to be measured.

  After that, as shown in FIG. 2B, when the train enters the train detection range of the crossing controller, the relay operation display lamp of the crossing controller lights up. The relay operation detection unit 10 that has detected the lighting of the relay operation display lamp outputs a relay operation detection signal indicating that the train has entered the train detection range of the railroad crossing controller to the time measurement unit 20. Thereby, the time measurement part 20 starts measurement of time. Moreover, the vehicle speed measurement part 30-1 measures the speed of the train which has entered the train detection range of the railroad crossing controller.

  Thereafter, when the train passes in front of the railroad crossing controller and advances from the train detection range of the railroad crossing controller as shown in FIG. 2C, the relay operation display lamp of the railroad crossing controller is turned off. The relay operation detection unit 10 that has detected that the relay operation display lamp is extinguished outputs a relay operation detection signal indicating that the train has advanced from the train detection range of the railroad crossing controller to the time measurement unit 20. Thereby, the time measurement part 20 complete | finishes measurement of time. In addition, the vehicle speed measurement unit 30-2 measures the speed of the train moving out of the train detection range of the railroad crossing controller.

  Thereafter, after the train has advanced from the train detection range of the railroad crossing controller (FIG. 2 (d)), the control section calculation unit 40 detects the train data input from the time measurement unit 20 and the train data input in advance. Based on the time and the train speed input from the vehicle speed measuring units 30-1 and 30-2, the control section length of the level crossing controller that is the measurement target is calculated.

  Next, train data input in advance to the control section calculation unit 40 of the control section length measurement system of the present embodiment will be described. FIG. 3 is a diagram illustrating a vehicle used for calculating a control section length of a crossing controller that is a measurement target in the control section length measurement system of the present embodiment. FIG. 3 shows an example of a two-car train. Even when the number of trains is different, it can be considered as in the following description.

  As described above, the railroad crossing controller detects a train when the track circuit is short-circuited by the train axle. Therefore, the railroad crossing controller detects the entry of the train when the axle in front of the first vehicle of the train enters the train detection range, and the train's control when the axle behind the last vehicle of the train advances from the train detection range. Detect advance. Therefore, in calculating the control section length by the control section calculation unit 40, it is necessary to consider the length between the train axles.

  As shown in FIG. 3, the length between the axles of a train can be calculated by the length between the axles of one vehicle, the length between the axles of two vehicles, and the number of trains. . That is, the number of trains is multiplied by the length between the axles of one vehicle, and the number of trains is subtracted by 1 and the length between the two axles is multiplied by the number of trains. The total value of the distance between the axles is the length between the axles of the entire train.

  Next, a method for calculating the control section length in the control section calculation unit 40 of the control section length measurement system of the present embodiment will be described. The control section calculation unit 40 is measured by the following equation (1) based on train data input in advance, train detection time input from the time measurement unit 20, and train speed input from the vehicle speed measurement unit 30. The control section length X of the target crossing controller is calculated.

  In the above equation (1), V is the train speed [Km / h], T is the train detection time [sec], n is the number of train formations [both], and A is the length between the axles of one vehicle [m]. ], B shows the length [m] between the axles between two vehicles. The train speed V is a value obtained by averaging the train speed when entering the train detection range of the railroad crossing controller and the train speed when moving outside the train detection range.

  In addition, the relay operation includes a delay time when the relay is switched from the OFF state to the ON state (OFF → ON delay time), and a delay time when the relay is switched from the ON state to the OFF state (ON → OFF delay time). and so on. Therefore, when there is a difference in the delay time, a more accurate control section length X can be calculated by correcting the train detection time T. Further, even when there is a difference between the train detection time T measured by the time measuring unit 20 and the time when the relay is actually in the ON state, a more accurate control section length X is calculated by correcting the train detection time T. can do. A calculation formula for calculating the control section length X in consideration of the correction of the train detection time T is shown in the following formula (2).

  In the above equation (2), d indicates a correction time [sec]. The correction time d is the difference between the relay OFF → ON delay time and the ON → OFF delay time as described above, the train detection time T measured by the time measuring unit 20 and the actual relay operation time. It is time such as the difference time.

  Next, a processing procedure of the control section length measurement system of this embodiment will be described. FIG. 4 is a flowchart showing a processing procedure of control section length measurement in the control section length measurement system of the present embodiment.

  The control section length measurement system of the present embodiment is installed as shown in FIG. 2A on a crossing controller that is a measurement target. First, in step 10, the length A between the axles of the vehicle and the length B between the axles of the vehicles, which are data of the train entering the train detection range of the railroad crossing controller, are set in the control section calculation unit 40. . Thereafter, the relay operation detection unit 10 starts detecting the operation state of the relay.

  Thereafter, in step S20, the time measuring unit 20 determines whether or not the relay operating state detected by the relay operation detecting unit 10 is the ON state. If the relay is not ON, step S20 is repeated. If the relay is in the ON state, the time measurement unit 20 starts measuring time in step S30.

  Thereafter, in step S40, the vehicle speed measuring unit 30 measures the speed of the train that has entered the train detection range of the railroad crossing controller.

  Thereafter, in step S50, the time measuring unit 20 determines whether or not the relay operating state detected by the relay operation detecting unit 10 is an OFF state. If the relay is not OFF, step S50 is repeated. If the relay is in the OFF state, in step S60, the time measuring unit 20 ends the time measurement.

  Thereafter, in step S70, the vehicle speed measuring unit 30 measures the speed of the train that moves out of the train detection range of the railroad crossing controller.

  Thereafter, in step S80, the control section calculation unit 40 sets the train data set in advance, the train detection time T input from the time measurement unit 20, and the train speed V input from the vehicle speed measurement unit 30. Based on the above, the control section length X of the crossing controller that is the measurement target is calculated by the above equation (1). In addition, when correction | amendment of the train detection time T is required when calculating the control area length X in step S80, the control area length X is calculated by the above Formula (2).

  In this way, the control section length of the level crossing controller is calculated based on the operating state of the relay operated by the track circuit of the level crossing controller.

  In the present embodiment, the configuration has been described in which the control section length X is calculated at the measurement site by the control section calculation unit 40. However, in the case where it is not necessary to calculate the control section length X at the measurement site, for example, the control section length X A personal computer (PC) can also be used as a function of the calculation unit 40. In this case, the train detection time T measured by the time measurement unit 20 and the train speed V measured by the vehicle speed measurement unit 30 are recorded. Later, the train data, the recorded train detection time T, and the train speed are recorded. V is input to the PC, and the control section length X is calculated by a program provided in the PC.

  Here, an example of the calculation result of the control section length X by the control section calculation unit 40 of the present embodiment is shown in FIG. FIG. 5 shows the train detection time T measured by the time measurement unit 20, the train speed V measured by the vehicle speed measurement unit 30 (the train speed at the time of entry and the train speed at the time of entry), train data (the number of trains, 4 is a table summarizing reference values of the length A between the axles of the vehicle and the length B between the axles of the vehicle, the calculated control section length X, and the control section length X measured by a conventional electric inspection vehicle. . Further, the calculated value of the control section length X shown in FIG. 5 is a value calculated by the above equation (2) with the correction time d set to 0.5 [sec]. In the train speed V, an example where the train speed at the time of entry and the train speed at the time of advance are the same value (upper part of FIG. 5) is an example of a straight section in the middle of the station. An example (lower part of FIG. 5) in which the train speed at the time of advance is a different value is an example of a section within a station premises. In the section of the station yard, the train speed changes greatly because the train stops at the station.

  As can be seen from FIG. 5, the control section length X of the level crossing controller measured and calculated by the control section length measurement system of the present embodiment is within the range of the control section length X measured by the conventional electric inspection vehicle. I understand that. In general, the control section length of the crossing controller is set to 30 [m], and its error is 5 [m]. It can be seen that the control section length X of the crossing controller to be measured, calculated from the measurement result by the control section length measurement system of the present embodiment, is within the set range. If the control section length X of the actual level crossing controller to be measured is 30 [m], the control section length X measured by the control section length measurement system of the present embodiment is more conventional. It can be said that the measurement can be performed with higher accuracy than the control section length X measured by the car.

  As described above, according to the embodiment for carrying out the present invention, it is possible to calculate the control section length of the level crossing controller based on the operating state of the relay operated by the track circuit of the level crossing controller. As a result, in the conventional measurement of the control section length, there is no need to work on normal train operation due to train operation stoppage or change of operation time, etc. The length of the control section can be measured by a train operating in Further, it is possible to measure the control section length in a state where the influence on other level crossing control devices generated by using the track short circuit and the variation of the measurement result by the measurer are avoided.

  Further, in this embodiment, two vehicle speed measuring units 30 are provided, and the train speed when the train enters the train detection range of the level crossing controller to be measured, and the train moves out of the train detection range. In the present embodiment, the control section length X is calculated by measuring the train speed twice with the train speed at the time of going. However, in the present invention, the configuration of the vehicle speed measuring unit 30 is not limited. For example, the vehicle speed measuring unit 30 is provided, and the vehicle speed is measured when the train enters the train detection range of the level crossing controller to be measured and when the train advances outside the train detection range. The train speed can be measured twice by changing the direction of the section 30. In the present invention, the method for changing the direction of the vehicle speed measuring unit 30 is not limited.

  In the present embodiment, the train speed measured by the vehicle speed measuring unit 30 is the train speed when the train enters the train detection range of the level crossing controller that is the measurement target, and the train speed outside the train detection range. Although the two train speeds with the train speed at the time of advancement are measured, the control section length X is calculated using the value obtained by averaging the measurement results of the two train speeds. In the invention, there is no limitation regarding the number of times the train speed is measured by the vehicle speed measuring unit 30. In the present embodiment, the vehicle speed measurement unit 30 measures the train speed after the time measurement unit 20 starts measuring time and after the time measurement ends. In the invention, there is no limitation regarding the measurement timing of the train speed by the vehicle speed measuring unit 30. For example, measuring the train speed 4 before the train enters the train detection range of the level crossing controller to be measured, after entering, before the train advances outside the train detection range, and after entering the train. The control section length X can also be calculated using a value obtained by adding and averaging the four train speed measurement results. In addition, in this invention, it does not limit regarding the method of calculating the train speed V used for calculation of the control section length X from the measured train speed. For example, the train speed V calculated by weighting the value of the measured train speed according to the distance between the vehicle speed measuring unit 30 and the train can be used for calculating the control section length X.

In the present embodiment, the level crossing controller to be measured is provided with a relay operation display lamp, and the relay operation detection unit 10 uses a light sensor to turn on and off the relay operation display lamp to turn on the relay of the level crossing controller. Although the example in which the state and the OFF state are detected has been described, even when the level crossing controller to be measured includes a relay operation display lamp, the above-described current sensor or the like causes the relay of the level crossing controller to be turned on and off. Can also be detected. For example, the short circuit state in the track circuit of the railroad crossing controller is unstable due to the contact state between the rail and the axle of the train, and the relay operation indicator lamp is turned on and off even when the train is within the train detection range of the railroad crossing controller. In such a case, the current level of the relay control signal is measured by a current sensor or the like, and the level crossing controller relay detects the ON state and the OFF state based on the measured current level of the relay control signal. You can also.
In the present invention, the configuration of the sensor that detects whether the relay of the crossing controller is in the ON state or the OFF state is not limited to the optical sensor or the current sensor shown in the present embodiment, but is a relay of the crossing controller. Any configuration can be used as long as it can detect whether the device is in the ON state or the OFF state.

  The embodiment of the present invention has been described above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes various modifications within the scope of the present invention. It is.
