Description

[Technical field]

[0001] The present invention relates to a device for changing over a double-acting point machine of a railway line into a single-acting point machine. [Background technology]

[0002] For example, in interlocking renewal work at a large-scale station, plans are also made to streamline the premises in conjunction with the work, and as a result of the replacement or abolishment of unnecessary points, it may be the case that only one of a dual-acting point machine consisting of one and two points is used, and the other point is abolished and used.

[0003] (1. Description of the double acting point machine device)

[0004] 4 to 6 show schematic diagrams and circuit diagrams of a point control device in a relay interlocking device, for example. The point control device comprises a double acting point machine consisting of one single acting point machine (type B point machine) 1 and the other single acting point machine (type A point machine) 2 which operate in conjunction with each other, and a relay interlocking device 3 which controls these points 1 and 2.

[0005] 4, the relay interlocking device 3 is composed of an interlocking control panel 3a that controls the points 1 and 2, and a relay rack 3b that is connected to the points 1 and 2, and the relay interlocking device 3 is connected to the No. 2 point 1 via a signal cable 5, and the No. 1 point 2 and the No. 2 point 1 are connected by a signal cable 6. The relay interlocking device 3 and the No. 2 point 1 may also be connected via a signal instrument box 4 that serves as a relay point.

[0006] The signal instrument box 4 not only serves as a relay point for the control conditions output from the relay interlocking device 3, but may also house equipment for supplying power to the field equipment, and a device for creating control conditions for field equipment separate from the control conditions output from the relay interlocking device 3.

[0007] Then, as shown in Figures 5 and 6, in response to a normal / reverse position changeover instruction determined in the interlocking control panel 3a, normal position or reverse position changeover information created by the point control circuit section 7 of the relay rack 3b is input to the No. B point controller 1a of the No. B point 1 connected to the signal line 5a of the signal cable 5, and in response to the input normal position or reverse position changeover information, the No. B point controller 1a changes the No. B point 1 to the instructed open direction and holds it there.

[0008] Further, the normal position or reverse position switching information from the point control circuit section 7 of the relay rack 3b is input to the Type A point control device 2a of the Type A point 2, which is connected to the signal line 6a of the signal cable 6 branched off from the signal line 5a, and based on the input normal position or reverse position switching information, the Type A point control device 2a switches (moves) the Type A point 2 to the instructed open direction and holds it there.

[0009] The No. R point machine 1 has a No. R side opening direction information processing unit 8, and the No. A point machine 2 has a No. A side opening direction information processing unit 9.

[0010] The No. A side opening direction information processing unit 9 is connected to a point display circuit power supply 10 for displaying the normal or reverse opening direction on the opening direction display unit of the relay interlocking device 3 via the signal line 5b of the signal cable 5 and the signal line 6b of the signal cable 6 connected to the signal line 5b, and the No. A side opening direction information processing unit 9 is configured to detect the opening direction status of the No. A point 2 by the point display circuit power supply 10 and to notify the No. B side opening direction information processing unit 8 of the detected normal or reverse opening direction information via the signal line 6c of the signal cable 6.

[0011] The No. B side opening direction information processing unit 8 is connected to the point opening direction display relay unit (KR) 11 of the relay rack 3b via the signal line 5c of the signal cable 5, and the No. B side opening direction information processing unit 8 detects the open status of the No. B point 1 by the point display circuit power supply 10 via the signal line 6c, and notifies the KR 11 of the opening direction that coincides with the opening direction information and the opening direction information notified from the No. A side opening direction information processing unit 9, and in response to the notification, the KR 11 displays the opening direction on the display unit of the interlocking control panel 3a.

[0012] That is, the No. B opening direction information processing unit 8, for example, obtains the orientation information from the No. A side opening direction information processing unit 9 via 6c1 of the signal line 6c, and when it judges that the opening direction situation of the No. B point machine 1 is in the orientation, notifies the KR 11 of the orientation information via the signal line 5c, so that the orientation information is displayed on the display unit of the interlocking control panel 3a.

[0013] In addition, the No. B opening direction information processing unit 8, for example, obtains reverse position information from the No. A side opening direction information processing unit 9 via 6c2 of the signal line 6c, and when it determines that the opening direction situation of the No. B point machine 1 is reversed, notifies the KR 11 of the reverse position information via the signal line 5c, so that the reverse position information is displayed on the display unit of the interlocking control panel 3a.

[0014] (2. Explanation of the method for converting a conventional double-acting system into a single-acting system)

[0015] When the above-mentioned dual-acting point machine is made single-acting, that is, for example, when the type A point machine 2 is abolished and changed (switched) to only the type B point machine 1, it is necessary to make it possible to use it as a dual-acting point machine before the change and as a single-acting point machine after the change.

[0016] For this reason, conventionally, as shown in Figs. 7 to 9, display relays (KR12 for type B, KR14 for type A) for displaying the respective open statuses of the type B point machine 1 and the type A point machine 2 were provided in the relay rack 3b, and the combination of the type A KR and the type B KR was used to operate the KR11, which was then displayed on the interlocking control panel 3a.

[0017] That is, the signal cable 6 is removed from the bi-directional point device, and a display relay (No. B KR) 12 for displaying the open direction of the No. B point 1 is separately provided. Furthermore, the No. B side open direction information processing unit 8 is connected to the signal line 5b and changed to a circuit that detects the open status of the No. B point 1 and notifies the detected open direction information to the No. B KR 12 connected via the signal line 5c of the signal cable 5.

[0018] The No. B side open direction information processing unit 8 detects the open status of the No. B point machine 1 by the point display circuit power supply 10 via the signal line 5b, and notifies the No. B KR 12 of the open direction information via the signal line 5c of the signal cable 5.

[0019] In addition, a point display relay (No. A side KR) 14 for displaying the opening direction of the No. A point 2 is separately provided, and the No. A opening direction information processing unit 9 is connected to the point display circuit power supply 10 via a signal line 15b of a separately provided temporary cable 15, and the No. A side KR 14 and the No. A side opening direction information processing unit 9 are linked by the signal line 15c of the temporary cable 15.

[0020] Then, the No. A point control device 2a of the No. A point 2 is modified so that position or reverse switching information is input from the point control circuit section 7 of the relay rack 3b via the signal line 15a of the temporary cable 15.

[0021] Then, the temporary cable 15 connected to the other point machine to be discontinued is discontinued and removed after the switchover.

[0022] In addition, the above-mentioned KR14 and KR12 are connected to the above-mentioned KR11 via a separately provided logic circuit unit 16, and the logic circuit unit 16 is configured to notify the above-mentioned KR11 of the matching opening direction of the above-mentioned KR14 and KR12. As a result, the opening direction obtained by the logic circuit unit 16 is displayed on the display unit of the above-mentioned interlocking control panel 3a.

[0023] The logic circuit unit 16 has a single-action switch 16-1 which can set the open information of the other point indication relay to be abolished and a bypass circuit which passes through the open information, and by setting these simultaneously when switching, it is possible to prevent discrepancies in the open information when switching from a dual-action point to a single-action point.

[0024] In addition, in the point single-action switch 16-1, a configuration in which the open information of the other point display relay to be abolished is set is called an N switch. That is, in the N switch, for example, in FIG. 7, the C terminal and the N terminal are connected.

[0025] In addition, in the single-action switch 16-1, a configuration in which a bypass circuit that bypasses the other point indication relay circuit to be abolished is set is called an R switch. That is, in the R switch, for example, in FIG. 7, the C terminal and the R terminal are connected.

[0026] In the dual action point machine control device configured as described above, before switching from the dual action point machine to the single action point machine, the open information of the No. B point machine 1 and the open information of the No. A point machine 2 are notified to the No. A KR14 and the No. B KR12, respectively, and the open direction is notified to the KR11 by the logic circuit unit 16, and is displayed on the display unit of the interlocking control panel 3a.

[0027] Furthermore, when switching from a dual action point machine to a single action point machine, there is no signal from number A KR14, and only open information from number B KR12. However, by setting the single action point machine switch 16-1 to the R switch at the same time as switching from a dual action point machine to a single action point machine, the logic circuit unit 16 notifies the KR11 of only the open direction information of number B KR12, and as a result, the open direction is notified to the KR11 and is displayed on the display unit of the interlocking control panel 3a.

[0028] In this way, it is possible to convert a double acting point machine into a single acting point machine.

[0029] Note that the above has been explained in terms of a relay interlocking device, and the individual names have been described assuming a relay interlocking device, but the same applies to electronic interlocking devices and the like which perform the same operations, and the individual names in the above relay interlocking devices are concepts which include the individual names in electronic interlocking devices and the like; for example, the interlocking control panel is a concept which includes a system terminal, and the relay rack is a concept which includes an input / output relay rack or a traffic light controller, and the same applies in the explanations which follow.

[0030] For example, a double acting point machine is disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0031] [Patent Document 1] JP 2018-184013 A Summary of the Invention [Problem to be solved by the invention]

[0032] However, with the above-mentioned conventional method, the circuits and wiring within the points had to be changed, and the wiring of the relay interlocking device 3 had to be changed in order to temporarily install the above-mentioned Type A KR 14, Type B KR 12, and the above-mentioned logic circuit unit 16. In addition, a temporary cable 15 that is abolished and removed after the changeover was required, which resulted in a risk of incorrect wiring and an increase in the process and construction costs.

[0033] The present invention is intended to eliminate the above drawbacks. [Means for solving the problem]

[0034] The switching device from a dual action point machine to a single action point machine of the present invention comprises one single action point machine constituting a dual action point machine, the other single action point machine, one and the other single action point control devices provided on each of the single action points for moving each of the single action points to a normal position or a reverse position based on normal position or reverse position information from an interlocking device controlling each of the single action points, and a first signal to a power source for displaying the normal position or reverse position opening direction on an opening direction display unit of the interlocking device. a second side opening direction information processing unit provided on the other single acting point machine connected via a second signal line, the second side opening direction information processing unit detecting an opening direction of the other single acting point machine and notifying the detected opening direction to the first side opening direction information processing unit of the one single acting point machine via a second signal line; a single-acting device which is connected to and disconnected from a first signal line portion on one of the single acting point machines of the disconnected first signal line and a second signal line portion on one of the single acting point machines of the disconnected second signal line, the single-acting device having a through circuit portion which notifies the one-side opening direction information processing unit of normal position and reverse position information via the second signal line portion upon power input from the first signal line portion, and the single-acting device is characterized in that, when the single-acting device is connected to the first signal line portion on the one of the single acting point machines of the disconnected first signal line and the second signal line portion on the one of the single acting point machines of the disconnected second signal line, the one-side opening direction information processing unit notifies the relay unit of the open information of the one of the single acting point machines via the through circuit portion.

[0037] (3. Description of the Invention)

[0038] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0039] The same parts as those in the conventional explanation are designated by the same reference numerals and the explanation thereof will be omitted. EXAMPLES

[0040] As shown in Figures 1 to 3, the switching device from a dual-acting point machine to a single-acting point machine of the present invention comprises a single-acting device 17 and switching means 18 for switching the signal cable 6 connecting the type B point machine 1 and the type A point machine 2 of the dual-acting point machine from the type A point machine 2 to the single-acting device 17.

[0041] The switching means 18 is, for example, composed of a No. B side connector portion 18a provided at an end of the No. B side signal cable portion 19 obtained by separating the signal cable 6 into a No. B side signal cable portion 19 and a No. A side signal cable portion 20, and a No. A side connector portion 18b provided at an end of the No. A side signal cable portion 20, and the No. B side connector portion 18a and the No. A side connector portion 18b are formed to be connectable and disconnectable.

[0042] Further, the signal cable portion 19 on the signal side has a connector portion 18a on the signal side that is formed so as to be connectable to and disconnectable from the single-acting device connector portion 17a on the single-acting device 17.

[0043] The signal cable 6 is composed of the signal lines 6a, 6b, and 6c, and the signal line 6a is separated into a No. B side signal line portion 19a and a No. A side signal line portion 20a, the signal line 6b is separated into a No. B side signal line portion 19b and a No. A side signal line portion 20b, and the signal line 6c is separated into a No. B side signal line 19c and a No. A side signal line 20c, and the corresponding signal lines are connected by connecting the No. B side connector portion 18a and the No. A side connector portion 18b.

[0044] The single-acting device 17 is provided with an opening direction through circuit 17b, which is connected by the single-acting device side connector portion 17a to the No. B side signal line portion 19b and the No. B side signal line portion 19c of the No. B side signal cable portion 19 via signal lines 21 and 22, respectively. Then, in response to signals from the point display circuit power supply 10 via the No. B side signal line 19b and signal line 21, the opening direction through circuit 17b is configured to notify the No. B side opening direction information processing portion 8 of both information of the normal position and the reverse position via the signal line 22 and the No. B side signal line portion 19c.

[0045] That is, when the opening direction through circuit 17b receives a signal from the point display circuit power supply 10 via the signal lines 19b and 21, it notifies the No. 2 opening direction information processing unit 8 of position information via the signal lines 22a and 6c1, and notifies the reverse position information via the signal lines 22b and 6c2.

[0046] By the single-acting device 17, the No. B side opening direction information processing unit 8 detects the opening status of the No. B point 1 by the point display circuit power supply 10 via the signal line 19b etc., obtains the opening direction information, and since it obtains both normal position and reverse position information from the opening direction through circuit 17b, it notifies the KR 11 of the matching opening direction information of the point 1, i.e., the detected opening direction information, and by this notification, the KR 11 is configured to display the opening direction on the display unit of the interlocking control panel 3a.

[0047] That is, the No. B side opening direction information processing unit 8 notifies the KR 11 of the normal position when the No. B point 1 is in the normal position by the opening direction through circuit unit 17b, and notifies the KR 11 of the reverse position when the No. B point 1 is in the reverse position.

[0048] In the present invention, due to the above-mentioned configuration, before switching from the dual action point machine to the single action point machine, the type B side connector portion 18a and the type A side connector portion 18b are connected to each other.

[0049] This makes it possible to operate each point of the double acting point machine as in the conventional case.

[0050] In addition, when switching from a double-acting point machine to a single-acting point machine, the No. R side connector portion 18a is connected to the connector portion 17a of the single-acting device, thereby making it possible to notify the KR11 of the opening direction of the No. R point machine.

[0051] In addition, the normal or reverse switching information created by the switch control circuit section 7 of the relay rack 3b from the No. R signal line section 19a of the signal cable 6 is not connected to the single-acting device side connector, so it remains unprocessed.

[0052] According to the present invention, a dual action point machine can be switched to a single action point machine simply by switching the connectors, and wiring errors can be prevented.

[0053] The above explanation is for the case where only one point machine (type B point machine) 1 is used and the other point machine (type A point machine) 2 is abolished. However, if one point machine (type B point machine) 1 is abolished and only the other point machine (type A point machine) 2 is used, the signal cable 5 is disconnected from the type B point machine 1 and connected to the type A point machine 2 in the same state as when the signal cable 5 was connected to the type B point machine 1.

[0054] In addition, the circuit configuration of the No. A side opening direction information processing unit of the No. A point 2 is changed so that it is the same as the circuit configuration of the No. B side opening direction information processing unit, and the circuit configuration of the No. B side opening direction information processing unit is changed so that it is the same as the circuit configuration of the No. A side opening direction information processing unit.

[0055] In addition, the signal cable 6 connected from the No. B point machine 1 to the No. A point machine 2 is connected from the No. A point machine 2 to the No. B point machine 2 in the same manner as the No. B point machine 1 and the No. A point machine 2 are connected.

[0056] In other words, the circuit configuration and signal cable connection configuration of the remaining point machine shall be the same as the circuit configuration and signal cable connection configuration of the No. B point machine 1 described above, and the circuit configuration and signal cable connection configuration of the point machine to be removed (discontinued) shall be the same as the circuit configuration and signal cable connection configuration of the No. A point machine 2 described above.

[0057] More specifically, the normal position or reverse position switching information created by the point control circuit section 7 of the relay rack 3b is input to the Type A point control device 2a of the Type A point 2 connected to the signal line 5a of the signal cable 5, and based on the input normal position or reverse position switching information, the Type A point control device 2a switches the Type A point 2 to the instructed open direction and holds it there.

[0058] In addition, position or reverse switching information from the switch control circuit section 7 of the relay rack 3b is input to the No. B switch control device 1a of the No. B switch 1, which is connected to the signal line 6a of the signal cable 6 branched off from the signal line 5a, and based on the input position or reverse switching information, the No. B switch control device 1a switches (moves) the No. B switch 1 in the instructed open direction and holds it there.

[0059] The No. B side opening direction information processing unit 8 is connected to the switch indication circuit power supply 10 of the relay interlocking device 3 via the signal line 5b of the signal cable 5 and the signal line 6b of the signal cable 6 connected to the signal line 5b, and the No. B side opening direction information processing unit 8 detects the opening direction status of the No. B point 1 by the switch indication circuit power supply 10 and notifies the No. A side opening direction information processing unit 9 of the detected normal or reverse opening direction information via the signal line 6c of the signal cable 6.

[0060] The No. A side opening direction information processing unit 9 is connected to the point opening direction display relay unit (KR) 11 of the interlocking control panel 3a via the signal line 5c of the signal cable 5, and the No. A side opening direction information processing unit 9 detects the open status of the No. A point 2 by the point display circuit power supply 10 via the signal line 6c, and notifies the KR 11 of the opening direction that coincides with the opening direction information and the opening direction information notified from the No. B side opening direction information processing unit 8, and in response to the notification, the KR 11 displays the opening direction on the display unit of the interlocking control panel 3a.

[0061] That is, the No. A opening direction information processing unit 9, for example, obtains the orientation information from the No. B side opening direction information processing unit 8 via 6c1 of the signal line 6c, and when it judges that the opening direction situation of the No. A point 2 is in the orientation, notifies the KR 11 of the orientation information via the signal line 5c, so that the orientation information is displayed on the display unit of the interlocking control panel 3a.

[0062] In addition, the No. A opening direction information processing unit 9, for example, obtains reverse position information from the No. B side opening direction information processing unit 8 via 6c2 of the signal line 6c, and when it determines that the opening direction situation of the No. A point 2 is reversed, notifies the KR 11 of the reverse position information via the signal line 5c, so that the reverse position information is displayed on the display unit of the interlocking control panel 3a.

[0063] By configuring in this manner, providing the switching means 18 on the signal cable 6, and using the single-acting device 17, even when the type B point 1 is eliminated and only the type A point is used, it is possible to easily change from dual acting to single acting, as in the above case.
