Description

  The present invention relates to an electronic interlocking device and an interlocking inspection time shortening method, and more particularly to a time shortening when performing interlocking inspection.

  In order to safely configure a train route in a station yard where a large number of train routes are concentrated and branched, the train route such as a switch device, a signal device, a sign device, a display device, etc. according to the entry or advance of the train. It is necessary to control the operation of many devices (hereinafter referred to as “field device”) involved in the configuration under a predetermined interlocking condition. Although it is possible to control the operation of on-site equipment manually, it is difficult to increase transportation efficiency and to ensure safety if performed manually. Therefore, today, a track circuit device for tracking a vehicle is installed along the track, and using the information obtained from the track circuit device and interlocking data corresponding to the interlocking conditions when configuring the train route, Electronic interlocking devices that automatically perform configuration have been introduced in many stations and stops.

  When this electronic interlocking device is newly installed or when the existing electronic interlocking device is changed, it is necessary to perform interlocking inspection to check whether the electronic interlocking device and field equipment operate correctly under the specified interlocking conditions. is there. Interlock inspection is to inspect whether the interlocking conditions described in the interlocking chart and the operation of the electronic interlocking device match, and the inspection items are stipulated in JIS, for example, approaching lock, holding lock, Specific inspection items related to the unlocking element and the indicating element are determined. The interlocking condition is a condition related to a course (orbit section) for controlling the traffic light, and is, for example, a track section or a time signal of the traffic light. In the electronic interlocking device, the interlocking process described in the interlocking chart is converted into data and interlocking processing is performed. However, if the interlocking inspection is executed according to the timetable described in the interlocking chart, the inspection time is the same as the time of the time base. As the number of inspection items increases in proportion to the size of the station, the time required for the interlocking inspection is further increased, and the construction period of the station is prolonged due to the change of the electronic interlocking device. It will be.

  As a means for solving such a problem, the prior art shown in the following Patent Document 1 sets a multiple of elapsed time to a multiple larger than 1 when performing linked processing using linked logical data. It is configured to reduce the time required for hourly count processing.

Japanese Patent No. 3895706

  However, the prior art disclosed in Patent Document 1 sets a multiple of elapsed time to a multiple larger than 1 when performing linked processing using linked logical data, and is included in the linked data using this multiple. It is configured to change the time base. Therefore, it is impossible for the operator to estimate the timepiece to be inspected unless the multiple is known. Even if the multiple is known, if the worker himself / herself does not check whether the unlocking such as the approaching lock is performed in the time until the counting is completed, the shortened time element is displayed on the linked chart. It cannot be determined whether it is related to the interlocking condition. Therefore, it is not only a burden to measure shortened timepieces, but there is also a possibility that the interlocking condition of the inspection object may be misunderstood, so that the need to further improve the efficiency of the interlocking inspection can be met. There was a problem that it was not possible.

  The present invention has been made in view of the above, and an object of the present invention is to obtain an electronic interlocking device and a interlocking inspection time shortening method capable of further improving the efficiency of interlocking inspection.

  In order to solve the above-described problems and achieve the object, the present invention provides a storage unit that stores interlocking data corresponding to interlocking conditions when configuring a train route, and interlocks according to the interlocking data acquired from the storage unit.

FIG. 3 is a flowchart for explaining the operation of the electronic interlocking device according to the embodiment of the present invention.

  Embodiments of an electronic interlocking device and an interlocking inspection time shortening method according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment.
FIG. 1 is a configuration diagram of an electronic interlocking device 50 according to an embodiment of the present invention. FIG. 2 is a diagram for explaining the interlocking conditions. FIG. 2 illustrates an interlocking table 100 constituting the interlocking chart.

  In FIG. 1, an electronic interlocking device 50 is connected to a track circuit device 60 having a plurality of track circuits (not shown), and switches, signal devices, signage devices, and display devices related to the configuration of the train route. Are connected to a field device 65 such as. The electronic interlocking device 50 shown in FIG. 1 mainly has a storage unit 10, an interlocking processing unit 20, and a site that controls each operation of the field device 65 according to the device control data created by the interlocking processing unit 20. A device control unit 30 and a display control unit 40 are included.

  The storage unit 10 stores interlocking data 10a for performing interlocking processing. This interlocking data 10a corresponds to the interlocking conditions at the time of constructing the train route, and is, for example, data obtained by converting the interlocking conditions described in the interlocking table 100 shown in FIG.

  The display control unit 40 is connected to the interlocking processing unit 20 and includes an input unit 32 and a display unit 34. The input unit 32 includes a keyboard, an operation panel, and the like used for inputting signals to the interlocking processing unit 20 and setting operating conditions of the interlocking processing unit 20. The display unit 34 is configured by a monitor device, a display panel, and the like that can display the processing result of the interlocking processing unit 20 and the interlocking table 100.

  The display unit 34 displays time information transmitted from the time information transmission unit 12 and information related to the state of the field device 65.

  A portion surrounded by a dotted line in the interlocking processing unit 20 corresponds to a time element information processing unit 21. The time element information processing unit 21 includes a time element information transmission unit 12, a time element setting unit (mode setting unit) as main components. ) 14 and hourly count execution unit 16. In addition to the time information processing unit 21, the interlocking processing unit 20 uses the interlocking data 10 a stored in the storage unit 10 and the status information of the track circuit obtained from the track circuit device 60. A function of creating device control data (data for controlling the operation of the on-site device 65) at the normal time of normal operation and at the time of maintenance at which maintenance work is performed is also provided. In the present embodiment, this function is provided. I will omit the explanation.

  The time element setting unit 14 sets either the normal mode or the shortened mode as the time element count mode. The normal mode is a mode in which the time base count is executed in the same time as the time base set in the interlocking data 10a, and the shortening mode is the time base count in the time shorter than the time base set in the interlocking data 10a. It is a mode to execute. These modes are turned on, for example, when the electronic interlocking device 50 is turned on and the interlocking processing unit 20 is initialized. These modes are read by the time element setting unit 14 and the setting of the time element count mode is completed.

  For example, in the initial setting process when the electronic interlocking device 50 is turned on, the time element count execution unit 16 reads the normal mode and / or the shortening mode set in the time element setting unit 14 and stores it in the interlocking data 10a. The linked data 10a read is read. When the time data is included in the read linked data 10a and the read mode is the normal mode, the time data count execution unit 16 uses the time data set in the linked data 10a. Perform a count. Further, when the time data is included in the read interlocking data 10a and the read mode is the shortened mode, the time base count execution unit 16 uses the time base set in the interlocking data 10a. The time element is replaced with a time shorter than the time element, and the time element count is executed with the time element after the replacement. Then, when the set time piece has elapsed, the time piece count execution unit 16 sets a flag indicating completion of the time piece in the interlocking data 10a. By setting this flag, the interlocking processing unit 20 can execute processing after completion of the time count. In the hourly count execution unit 16, these processes are executed in the order of the interlocking data 10 a in the storage unit 10.

  The time element count execution unit 16 reads the time element count mode of the time element setting unit 14 only when the power is turned on, for example, after the electronic interlocking device 50 starts the interlock operation, Even when the count mode setting is switched, the mode switching in the hourly count execution unit 16 is not performed. That is, even if the time element setting unit 14 switches from the normal mode to the shortened mode for some reason while the train is operating, the time element count execution unit 16 does not read the time element count mode, so the time element setting mode 14 is shortened. No prime count is performed in mode. In this way, the interlocking processing unit 20 ensures that switching from the normal mode to the shortened mode is not performed during actual operation, in other words, ensures unlocking by the time element in the normal mode during actual operation. Is possible.

  Note that the time replaced by the hourly count execution unit 16 in the shortened mode is, for example, 3 seconds or 5 seconds. In this way, the time base count execution unit 16 replaces the time base set in the interlocking data 10a with a time shorter than the time base, thereby reducing the time required for the time base counting process, and the interlocking data 10a. It is possible to complete the interlocking inspection without waiting until the time element that is set to, that is, when the time element unlocking such as the approaching lock or the holding lock described in the interlocking table 100 has passed. It becomes.

  When the time data setting unit 14 reads the interlocking data 10a, the time element information transmitting unit 12 transmits the time base information set in the interlocking data 10a to the display unit 34. The display unit 34 receives the time element information transmitted from the time element information transmission unit 12, and visualizes and displays the value of the time element. By displaying the time element value on the display unit 34, the time element that is the target of the time element count processing in the time element count execution unit 16 (that is, the value of the time element described in the interlocking table 100) is confirmed. It becomes possible to do.

  For example, in the “approach locked or retained lock” column of the interlocking table 100 shown in FIG. 2, time elements such as “120 seconds”, “90 seconds”, “60 seconds”, “30 seconds”, etc., in order from the top. Is described. These time elements are also set in the interlocking data 10a. Then, on the display unit 34, for example, the time element (for example, “120 seconds”) of the interlocking data 10a that is the execution target of the time element count by the time element count execution unit 16 is displayed. However, when the time base count execution unit 16 is executing the time base count processing in the shortened mode, the count time is not 120 seconds but the time replaced by the time base count execution unit 16 (for example, 5 seconds). .

  In the above prior art, when interlocking processing using interlocking logical data is performed, a multiple of the elapsed time is set to a multiple larger than one, and the time element included in the interlocking data 10a is changed using this multiple. It is configured. Therefore, it is impossible for the operator to estimate the timepiece to be inspected unless the multiple is known. Even if the multiple is known, if the worker himself / herself does not check whether the unlocking such as the approaching lock is performed in the time until the counting is completed, the shortened time element is displayed on the linked chart. It cannot be determined whether it is related to the interlocking condition. Therefore, it is not only a burden to measure the shortened timepiece, but there is also a possibility that the interlocking condition of the inspection object is mistaken.

  The electronic interlocking device 50 according to the present embodiment is configured to display the time base set in the interlocking data 10a on the display unit 34 when the interlocking data 10a is read by the time base counting execution unit 16. ing. Therefore, the worker can understand the correspondence between the time element that is the target of the time element count processing by the time element count execution unit 16 and the time element described in the interlocking table 100.

  Hereinafter, the operation of the electronic interlocking device 50 will be described. FIG. 3 is a flowchart for explaining the operation of the electronic interlocking device according to the embodiment of the present invention. The interlocking processing unit 20 is set with a time base count mode when the interlocking process is performed by an operator. After the mode setting is completed, the interlock processing unit 20 is turned on. Is set (step S1).

  The normal mode and / or the shortening mode set in the time base setting unit 14 is read into the time base count execution unit 16 during the initial setting process when the power is turned on, and the interlocking data 10a stored in the interlocking data 10a is further stored. It is read by the hourly count execution unit 16 (step S2).

  When the time data is included in the interlocking data 10a (step S3, Yes), the time base count execution unit 16 determines whether or not the read mode is the normal mode (step S4).

  When the read mode is the normal mode (step S4, Yes), the time base setting unit 14 executes the time base count process with the time base set in the interlocking data 10a, and the interlocking data 10a The set hourly information is transmitted to the display unit 34 by the hourly information transmitting unit 12 (step S5). Then, when the time element has elapsed, the time element completion flag is set in the interlocking data 10a by the time element setting unit 14 (step S6).

  When the read mode is not the normal mode (step S4, No), the time base setting unit 14 replaces the time base set in the interlocking data 10a with a time shorter than this time base, and after this replacement The time element count processing is executed with the time element, and the information of the time element set in the interlocking data 10a is transmitted to the display unit 34 by the time element information transmitting unit 12 (step S7). Then, when the raw time has passed, the process of step S6 is performed.

  In step S3, when the time data is not included in the interlocking data 10a (step S3, No), the interlocking processing unit 20 executes interlocking processes other than the time element counting process based on the interlocking data 10a (step S8). ).

  The display unit 34 may display the time information from the time information transmission unit 12 and the contents of the interlocking data 10a under examination in association with each other. By displaying in this way, it is possible to reduce the possibility of misrecognizing the interlocking condition that is the target of time counting.

  As described above, the electronic interlocking device 50 according to the present embodiment includes the storage unit 10 that stores the interlocking data 10a corresponding to the interlocking conditions when configuring the train route, and the interlocking data acquired from the storage unit 10. The electronic interlocking device 50 includes an interlocking processing unit 20 that executes interlocking processing according to 10a and a display unit 34 that displays a processing result of the interlocking processing unit 20, and the interlocking processing unit 20 stores the interlocking data 10a in the interlocking data 10a. A non-shortened mode (normal mode) that executes the time base count in the same time as the set time base and / or a shortened mode that executes the time base count in a shorter time than the time base set in the interlocking data 10a. The mode setting unit (14) to be set and the interlocking data 10a read from the storage unit 10 include a timepiece, and the mode set in the mode setting unit is the normal mode. In this case, the time base count is executed with the time base set in the interlocking data 10a, the time base is included in the interlocking data 10a read from the storage section 10, and the mode set in the mode setting section is shortened. In the case of the mode, the time element count execution unit 16 that replaces the time element set in the interlocking data 10a with a time shorter than this time element and executes the time element count with the replaced time element, and the storage unit The time element information transmitting unit 12 that transmits information related to the time element set in the interlocking data 10a read from 10 to the display unit 34 is provided. It is possible to shorten the construction period when 50 changes are made. Moreover, since the time element set in the interlocking data 10 a is displayed on the display unit 34, the correspondence between the time element that is subject to the time element counting process and the time element described in the interlocking table 100 is displayed depending on the worker. It is possible to understand the relationship.

  In addition, since the hourly count execution unit 16 according to the present embodiment uses a fixed value as the short time, the inspection time is set to a different value for each time set in the interlocking data 10a as in the prior art. This is not necessary, and the program in the hourly count execution unit 16 can be simplified and the inspection time can be further shortened.

  Further, the linked inspection time shortening method according to the present embodiment is a non-shortened mode in which the time base count is executed in the same time as the time base set in the interlocking data 10a corresponding to the interlocking conditions at the time of configuring the train route ( Normal mode) and / or a mode setting step for setting a shortening mode for executing the time count in a shorter time than the time set for the interlocking data 10a, and reading for reading the interlocking data 10a, the normal mode, and the shortening mode When the time data is included in the step and the read linked data 10a, and the read mode is the normal mode, the time code is executed with the time data set in the linked data 10a, and the read linked data If the data 10a contains a time element and the read mode is the shortened mode, the time element set in the interlocking data 10a A time element count execution step of replacing the time element with a time shorter than the time element and executing a time element count with the replaced time element, and a time element for transmitting information about the time element set in the interlocking data 10a to the display unit 34 Since the information transmission step is included, it is possible to shorten the construction period when changing the electronic interlocking device 50 by shortening the inspection time. Moreover, since the time element set in the interlocking data 10 a is displayed on the display unit 34, the correspondence between the time element that is subject to the time element counting process and the time element described in the interlocking table 100 is displayed depending on the worker.
