Description

[Detailed description of the device] <Industrial application field> The present invention uses the existing CTC (train centralized control) device as a new CTC device.
The present invention relates to a switching device for a CTC device suitable for switching to a device.

<Prior Art> CTC is a method of remotely controlling a large number of signal equipment in a wide area from one central command room to instruct train operation. That is, the CTC device is installed at each station in the central command room and the control section, and the commander of the central command room displays the tracks of the control section on the CTC display panel to operate the operation equipment and train operation transmitted from each station. While monitoring information such as the status, by remotely controlling the turning machines and traffic lights at each station, the train operation can be improved with a small number of personnel.

By the way, when switching from an existing CTC device to a new CTC device, the conventional general method is to install new and old devices in the central command room and each station respectively, and provide a changeover switch for both devices to manually operate. Is switching from the old device to the new device.

<Problems to be solved by the invention> In this method, if the functions of the old and new CTC devices are exactly the same, there is no problem if the CTC devices are sequentially switched, for example, overnight. , The old and new CTC devices often differ due to functional upgrades, etc. In this case, it is necessary to switch all CTC devices in the control section all at once within a limited short time from the last train until the first power generation car comes out.

Therefore, conventionally, switching personnel have been arranged in the central command room and each station so that they can contact each other by telephone or the like and carry out the switching work all at once. Therefore, as many switching personnel as the number of CTC devices to be switched were required. Also, since it is necessary for the switching personnel to have some technical knowledge in consideration of the case where trouble occurs during the work, it is difficult to secure the switching personnel when the number of stations is large, and the switching work becomes difficult. was there.

The present invention has been made in view of the above circumstances, and can be remotely operated from the central command room without arranging switching personnel at each station.
It is an object of the present invention to provide a CTC device switching device that can perform CTC device switching work.

<Means for Solving the Problem> Therefore, the present invention is a switching device for a CTC device having a central switching device (5) and a station switching device (6), wherein the central switching device (5) is Provided on the side of the central command room, switching command means (SW), information input means (NR) and timer means (T)
And central transmission line switching means (CR), switching command means (SW) from the existing old central or station CTC device (1,3) side to the new new central or station CTC device (2,4) side Generates command information for switching the information transmission path (7), and information input means (NR)
Inputs the command information issued by the switching command means (SW) to the old central CTC device (1), and the timer means (T) inputs the command information issued by the switching command means (SW) to start timing and start a predetermined time. Output is generated after a lapse of time, and the central transmission line switching means (C
R) operates by the output of the timer means (T) to switch and connect the information transmission line (7) from the old CTC central device (1) side to the new CTC central device (2) side, and the station switching device (6) , Provided at each station side away from the central command room, and equipped with station transmission line switching means (X
R) and station transmission line switching control means (NXR, NXPR), and the station transmission line switching means (XR) is from the old station CTC device (3) side to the new station C.
Switching the information transmission line (7) to the TC device (4) side, the station transmission line switching control means (NXR, NXPR) is the former central CTC device (1)
The switching operation of the station transmission line switching means (XR) is controlled based on the switching instruction information transmitted from the station to the old station CTC device (3) via the information transmission line (7).

<Operation> In such a configuration, when the switching command is output from the switching command means, the switching command information is input to the currently operating old CTC central device, and at the same time, the timer means starts operating to start timing. When the switching command information is input to the old CTC central device, a signal for switching control is input from the old CTC central device to the currently operating old CTC station device of each station via the information transmission path. Then, the switching control signal is output from the old CTC station device, and based on this, the station transmission line switching control means uses the old CTC.
After the switching information transmission to the station device is completed, the station transmission line switching means is operated to switch from the old CTC station device to the new CTC station device. Also,
The timer means sets a time sufficient for transmitting the switching information to all stations in the control section and outputs it after the time has elapsed from the start of operation, and outputs it by the central transmission line switching means.
Switch the transmission line from the central unit to the new CTC central unit.
As a result, CTC can be operated simply by switching operation on the central command room
Not only the central device, but also the CTC device at each station within the control section can be automatically switched.

Next, the operation of the switching device will be described with reference to the time chart of FIG.

When switching from the CTC device currently in use to a new CTC device, first switch the changeover switch SW to the a contact side. As a result, the relay ER drops and the drop contact ER1 closes, so that the relay NR operates. When the relay NR operates, its operating contact NR4 closes, and its contact information is input to the old CTC central unit 1 as switching command information, and at the same time, the other operating contact NR2 closes and the hour relay T starts to operate to measure time. Start. Also, when the relay ER falls, its switching contact ER3
Is switched to the b contact side, and the switching contact NR3 is switched to the a contact side by the operation of the relay NR.

When the switching command information is input to the old CTC central unit 1, the old CTC
The switching command information is sent as a pulse signal from the TC central device 1 to the information transmission path 7 via the N contact of the switching contact CR1 and transmitted to each station side. The switching command information transmitted to the station side is input to the old CTC station device 3 via the N contact of the switching contact XR1.
When this switching command information is input, the relay NXR operates by the output according to the pulse signal from the old CTC station device 3, its operating contact NXR1 closes and the relay NXPR operates, and its self-holding contact NXPPR1 closes. Self-holding,
Switching contact NXP R2 switches to the a contact side. In addition, the falling contact N
XR2 opens and relay EXPR falls, so its switching contact EXPR2
Switches to the b contact side. After that, when the output from the old CTC station device 3 disappears, the relay NXR falls and its fall contact NXR
Since 3 is closed, current is input to the magnetic holding relay XR from the right direction in the figure, and the switching contact XR1 is switched to the R contact side, and the information transmission path 7 is connected to the new CTC station device 4 side.

Then, the switching operation information from the central command room side is set to a time sufficient for being transmitted to each station, and the time relay T is output after the set predetermined time has elapsed from the start of the operation, whereby the operation is performed. Magnetic holding relay CR with contact T1 closed
Current is input from the right direction in the figure and its switching contact CR1 is R
Switching to the contact side, the information transmission path 7 is switched from the old CTC central device 1 side to the new CTC central device 2 side, and the switching work of the CTC device is completed.

If such a switching device is used, the CTC device at each station can automatically switch from the old CTC device to the new CTC device remotely by simply switching the switch SW on the central command room side. As described above, it is not necessary to allocate the work staff to each of the central command room and each station, but it is sufficient to allocate the work staff only to the central command room side, and the work staff can be greatly reduced. Also, without providing a new transmission line for switching command information transmission,
Information can be transmitted using the existing CTC transmission line 7.

By the way, when the switching work of the CTC device is performed, it is necessary to perform various tests on the new CTC device after the switching to confirm whether or not the system operates normally, which takes many days. Therefore, after switching to the new CTC device, it is necessary to switch back to the old CTC device in order to restore it before the first power generation car comes out. Therefore, in this embodiment, the switching can be performed.

That is, the changeover switch SW is switched from the a-contact side to the b-contact side. This causes the relay NR to drop and its fall contact NR1
Is closed, the relay ER operates, its operating contact ER4 closes, and that contact information is input to the new CTC central unit 2 as switching command information, and another operating contact ER2 closes, causing the hormonal relay T to operate. Start and start timing. Further, the switching contact NR3 is switched to the b contact side by the fall of the relay NR, and the switching contact ER3 is switched to the a contact side by the operation of the relay ER.

When the switching command information is input to the new CTC central unit 2, the new CTC
The switching command information is transmitted from the TC central unit 2 to the respective stations by the R contact of the switching contact CR1 via the information transmission path 7. The switching command information transmitted to the station side is input to the new CTC station device 4 via the R contact of the switching contact XR1, and the relay EXR operates by the output according to the pulse signal from the new CTC station device 4,
The operating contact EXR2 is closed and the relay EXPR operates, the self-holding contact EXPR1 is closed and self-holding, and the switching contact EXPR2 is switched to the a-contact side. In addition, the drop contact EXR1
Opens and the relay NXPR falls, so its switching contact NXPR2 switches to the b contact side. Then, when the output from the new CTC station device 4 disappears, the relay EXR falls and its fall contact EXR3
Is closed, a current is input to the magnetic holding relay XR from the left in the figure, and the switching contact XR1 is switched to the N contact side, and the information transmission line 7 is connected to the old CTC station device 3 side.

After that, the time relay T on the side of the central command room outputs after a lapse of a predetermined time, so that the operating contact T1 is closed and a current is input to the magnetic holding relay CR from the left direction in the figure, and the switching contact CR1 is Switching to the N contact side, switching the information transmission line 7 from the new CTC central unit 2 side to the old CTC central unit 1 side, and CT
Device C returns to its original state.

In this embodiment, the switching device is constituted by the relay, but it goes without saying that it may be constituted by using other circuit elements.

<Effect of the Invention> As described above, according to the present invention, the new / old model can be remotely operated from the central command room side using the existing CTC transmission line.
Since the CTC device can be switched, the switching work becomes extremely easy, and it is not necessary to allocate a worker to each station as in the conventional case, and the worker can be significantly reduced.
