Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a system for controlling changes in train operation-related information such as a train position, a train delay, a train destination, and a state of a railway signal held by a train control apparatus by using a radio communication system telephone. The present invention relates to a transmission method and system capable of automatically and sequentially transmitting a train or a train that has entered a specific section.

[0002]

2. Description of the Related Art Train operation status is generally grasped and managed.
CTC (= centralized traf) provided for each line section
This is performed by a train control device called a fic control system. Then, the current position of the train, the state of the railway signal, and the like are displayed on a CTC display panel installed at the central command center, and the dispatched commander sees this and grasps and manages the operation status of the train. The operation management of each train is performed by an operation management device (PRC = Programmed Rute Control) which is one of computer devices forming a CTC network.

In a normal operation state, the operation of each train and the switching of traffic lights and points are performed according to the contents programmed in the PRC. However, in the event of a shift to a special operating state due to an unexpected situation such as a vehicle accident, personal injury, a signal failure, or a breakage of a railroad crossing rod, the train's progress will be changed and the target operating state will be changed. It is necessary to notify the train of the changes. The details of the change include: changing the block system or block section, changing the train operation time, changing the train operating track, changing the arrival line at the arrival station platform, notifying the failure of the traffic light, and stopping the announcement of the traffic light. There are changes to hand signals, temporary slowing of trains and other changes.

Conventionally, when the operating state of a train shifts from a normal state to a special state, a driving notice ticket according to the contents of the change is issued to the target running train. Issuance of driving notice tickets can be roughly classified into two types: direct handing and wireless notification. In the case of the direct handing method, the contents of the driving notification ticket are first checked in the central command room, then transmitted by fax to the target station, and the staff in charge of the target station holds the driving notification ticket by fax. The train waits at the platform where the target train enters and hands it directly to the driver and conductor of the target train. After handing, the staff in charge of the station notifies the central command room of the completion of the notification, and the train crew who is handed operates the train according to the changed contents of the driving notification ticket. On the other hand, in the case of the wireless notification system, the contents of the driving notification ticket are orally instructed directly to the driver and conductor of the target train by radio from the central command room, and the driver and the conductor verbally repeat through the radio. is there.

[0005]

However, in the case of a method of directly handing out a driving notice ticket, the contents of the driving notice ticket are described and transmitted on a FAX sheet. However, there is a drawback in that time is required, the response time after an unexpected event occurs is prolonged, and it takes a long time to recover to a normal diamond. In addition, during the period from issuance of the driving notice ticket to notification of the target train
The station staff is involved, so many steps must be taken, the procedure is complicated and takes a lot of time, and the dedicated staff for transmitting driving notice tickets must be allocated at the station. However, there is a disadvantage that labor costs are increased. Furthermore, in this handing method, it was necessary to individually perform the operation on the target train, and it was necessary to sequentially issue a driving notice ticket to all the trains entering the specific section and notify the contents. . Therefore, from the perspective of overall train operation management, the same procedure must be performed for all trains,
It was extremely complicated, and the recovery to a normal diamond was a major cause for a prolonged period.

[0006] On the other hand, in the case of the wireless communication system as well, it is necessary to apply the same contents of the driving notice ticket individually to the target trains. Required, and the drawback was that the recovery to a normal diamond was prolonged. In addition, since the notification of the driving notification ticket is oral, it is unknown in the central command room whether or not the contents of the driving notification ticket have been correctly transmitted, and the procedure for preventing this is complicated and complicated. There was a disadvantage.

[0007]

SUMMARY OF THE INVENTION The present invention has been improved and eliminated in view of the above-mentioned conventional problems. The present invention is to notify a train which has entered a specific section in sequence, or A transmission method and a transmission system capable of notifying all trains at the same time are provided.

According to the present invention, it is possible to sequentially and automatically issue an operation status change command (notification of a driving notice ticket) to a monitor of a train that has entered a specific section. The trainer and conductor can see and confirm this directly. Also, a confirmation signal can be transmitted to the central command room. This makes it possible to omit the same repetitive operation performed by the commander.

Further, the means of claim 2 adopted by the present invention is as follows.
It stores the train operation related information held by the train operation management device, retrieves all the train information existing in the requested specific section from the stored information, and wirelessly communicates with the monitors of all the trains in this specific section. The change of the operation status is notified and displayed by the telephone of the communication system. This invention is the same as the invention of claim 1 except that the operation status change command (notification of the driving notice ticket) is applied to all trains in a specific section.

Further, the means of claim 3 adopted by the present invention is to accumulate train operation related information held by the train operation management device, extract train information in a requested specific section from the accumulated information, and The change of operation status is notified and displayed on the monitor of the corresponding train in the specific section by wireless communication telephone, and the result of transfer from / to each train is displayed on the monitor to make it easy to drop out of information transmission. I can check it. According to the present invention, all the trains intervening in the specific section can be displayed on the monitor of the central command room, and it is possible to confirm at a glance whether or not the transfer of the operation status change command has been completed.

According to a fourth aspect of the present invention, there is provided means for storing train operation related information held by the train control device, inputting a change in train operation status, and providing a request from the stored information. Information providing means for instructing the train to be applied to any of the specific information taken out in response thereto and the input change information of the train operation status, and wireless communication for transmitting the instruction content of the information providing means Means constitute a transmission system of train operation related information. This system is a configuration for realizing the method according to claims 1 to 3.

This is a transmission system for related information. The confirmation of the change in the train operation status can be transmitted simultaneously to the departments involved in the train operation, which is convenient.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a schematic diagram showing the entire system for transmitting train operation related information (hereinafter, referred to as “the present invention system”) according to an embodiment of the present invention. As shown in the figure, the central part of the system of the present invention is a computer, and has a PRC (train operation management device) 2 that forms a CTC network 1 that is a train control device.
For this PRC 2, a PRC acquisition device 3 that acquires information about the train operation status in real time, a line image creation device 4 that represents a diamond for each train in one line, The operation status server 5 for storing information is connected to the LAN.

[0014] Change of operation status (contents of driving notice ticket)
, An information providing device 7 for managing operation status change commands, and wireless communication means (DoCoMo of NTT DOCOMO).
A CoMoDopa network 8 is LAN-connected to the network through a connection device such as a router. The information providing device 7 determines whether or not to transmit the change to a specific train based on the change in the operation status input from the command device 6 and the real-time information on the operation status stored in the operation status server 5. It is a management device that determines whether or not. On the other hand, the train 10 has a base station 9 through a mobile phone 11 or the like.
A vehicle-mounted device (for example, a notebook personal computer) 12 that receives a change in the operation status (driving notice ticket) transmitted from the computer is mounted, the contents of which are displayed on a monitor 13, and a printer 14 is provided as necessary. Is to be printed out. It is also possible to transmit necessary items from a keyboard (not shown) of the on-board device 12.

Next, a method of transmitting train operation related information using the system of the present invention configured as described above will be described with reference to the flowchart shown in FIG. First, a description will be given of a case where a driving notification ticket is individually and automatically notified of a train sequentially invading a specific section. As such a situation, it is conceivable, for example, that a takeoff rod is broken due to excessive crossing of the automobile. If the railroad crossing rod is broken, there is nothing to block the railroad crossing when entering the train. Therefore, in order to ensure train operation in such a state, in order to prevent collisions and contact accidents between pedestrians and cars and trains at railroad crossings, the train is slowed down in advance at a speed that allows it to stop immediately. Operation status needs to be changed. Such changes need to be made for all trains entering the target railroad crossing.

In the system of the present invention, when a notification reason (a slow operation at a target railroad crossing is performed) and a section to which the railroad crossing belongs are input from the command device 6, the information providing device 7 stores the operating status stored in real time in the server. 5 to search for a train entering the requested specific section. If there is a train coming in, the command device 6
Is transmitted through the communication means 8 and the base station 9 shown in FIG. On the other hand, the on-board device 12 receives the train 10 that has entered the specific section via the mobile phone 11 and displays it on the monitor 13. The contents of the notice are described, for example, on a driving notice ticket created in the form (form) shown in FIG. In this case, it is sufficient to select “slow” from the “free text” drop-down menu of the other items and input the necessary items in text. Such notification is automatically performed sequentially for the trains 10 that have entered the specific section. Therefore, the dispatcher can input a notification reason and a specific section only once to notify all of the trains entering all the specific sections. The crew of the train that has received the notification may transmit a confirmation signal to the commander.

Next, for example, if the safety of the Sanyo Main Line is confirmed by inspection from a state in which all trains are deactivated due to an earthquake or the like and operation is resumed all at once, all trains in the line section will be In some cases, restart of operation is instructed. In the system of the present invention, by inputting the notification reason, the specific section (line section), and the designation of all the trains with the command device 6, the information providing device 7 controls all the trains in the corresponding section. The call is transmitted through the communication means 8 and its base station 9. Then, the on-board devices 12 of all the trains 10 receive the notification reasons through the mobile phone 11 as a mobile and display them on the monitor 13. Each crew train 1
The operation of 0 may be restarted. As described above, the notification reason is notified to all the trains in the specific section at the same time, so that the time required for the recovery to the normal schedule can be significantly reduced as compared with the case where the notification is performed individually.

In the system of the present invention, an answer-back system is employed to confirm whether or not the contents notified to each of the trains 10 have been securely transmitted. Is displayed on the monitor in the central command room. This ensures that the notification is given,
It is possible to prevent occurrence of human error such as a commander or a crew member.

Incidentally, the present invention is not limited to the above-described embodiment, but can be appropriately changed. For example, the content of the notification reason depends on the type of accident or failure that occurred.
Depending on the contents and the like, it can be changed as appropriate, and depending on the contents of the notification reason, it may be transmitted to the station side to switch points, or may be transmitted to the associated facilities. It is also possible to designate each train and transmit it individually, as in the prior art. Further, the communication means 8 includes N
Although a case has been described in which transmission is performed from the base station 9 to each train 10 through the mobile phone 11 using the TT DoCoMo DoCoMo Dopa network, communication means using another wireless telephone system may be used. The wireless telephone in this case includes another PHS-type telephone and the like.

[0020]

As described above, in the present invention,
The train operation management device accumulates train operation related information, retrieves information on trains that have sequentially entered the requested specific section from the accumulated information, and monitors each train that has entered the specific section. In response to this, a change in operation status is notified and displayed by a wireless communication type telephone.
Therefore, the operation status change command (notice of driving notice ticket)
It is possible to sequentially and automatically perform the monitoring of the trains entering the specific section, and the driver and conductor of each train can directly see and confirm this, and send a confirmation signal to the central command room. You can also send it. This makes it possible to omit the same repetitive operation performed by the commander. Therefore, it is possible to remarkably shorten the time required for the operation of restoring to a normal schedule.
