Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a train entrainment management system, and in particular provides command information from the center to the crew members of each train for timetable rescheduling such as change of arrival number or change of evacuation number caused by train disruption etc. This invention relates to a train-to-train command transmission device that can reliably transmit commands at appropriate timing.

Conventionally, various command information for train rescheduling has been sent from the central government using guidance radio or train radio.

In this type of system, the exchange of information between the center and the train was carried out in the form of dialogue between the dispatcher and the crew members, so the crew members could reliably confirm the command information, but on the other hand, the following problems occurred: There were drawbacks. 01 Due to the interactive format, it takes a lot of time to read the train and send information,
In the case of a major timetable disruption that requires the transmission of commands to many trains at the same time, the task of transmitting commands increases significantly, making it difficult to reliably transmit the commands at the appropriate time, and also making command judgment, which is the original task of the dispatcher. Business operations will be significantly hindered.

[2] If a computer-based entrainment management system is introduced, detailed timetable rescheduling decisions based on the computer's judgment must be made through the dispatcher each time.
The introduction of computers actually increases the task of transmitting commands for dispatchers, and there is no labor-saving effect.

In addition, in recent years, command transmission based on data transmission between the ground and onboard has been considered, but in such a method, the disadvantages of [1] and (2) of the above dialog format are eliminated, but,
On the other hand, an answer back from the train side in response to a command being transmitted from the center to the train had the disadvantage that it simply meant that the receiver on the train had received the information, so it did not necessarily mean that it was correctly transmitted to the train crew.

Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 50-107608, communication between the ground and the vehicle is enabled only in a specific service area, and when the vehicle reaches this area, the central processing unit , devices that display scheduled commands (for example, train departure instructions) to the crew are known.

According to this system, periodic commands such as those issued while a vehicle is stopped at a station can be automatically issued from the central processing unit, and the burden on the central dispatcher can be reduced accordingly.

However, in addition to the above-mentioned regular commands, the commands that should be conveyed from the central dispatcher to the crew members on board include train rescheduling commands such as arrival number changes and evacuation changes that occur due to timetable disruptions, etc. as mentioned at the beginning. Some things, like information, are contingent. These commands must be made based on the comprehensive judgment of the dispatcher, and it is difficult to automate them. Therefore, in the technique disclosed in the above-mentioned publication, the dispatcher must continue to monitor the vehicle until it reaches a service area suitable for issuing a command. We must not let the timing slip away under any circumstances. Therefore, the burden on the central dispatcher becomes heavy. SUMMARY OF THE INVENTION An object of the present invention is to provide a train-to-train information transmission device that can reduce the burden on a central dispatcher and can reliably transmit commands.

According to the present invention, the central dispatcher can input in advance the content of the command to be given to the crew members on the train and the timing (train position) for giving the command from the setting console.

This command information is stored, and when the train arrives at the position where the command should be given, the command can be transmitted from the center to the train and displayed to the crew. Therefore, the dispatcher does not need to time each command to give instructions, and the burden on the dispatcher is reduced.

Further, the vehicle is configured to receive a command transmission confirmation signal from a crew member on the vehicle to the center, and is provided with means for monitoring whether or not this reception is performed within a predetermined time.

Therefore, reliable confirmation of command transmission is possible. Furthermore, the stored command information is reset in response to the train passing the command transmission point, thereby reducing the capacity of the central storage means. An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows CTC as a data transmission device between the field and the center.
This is an example in which an electromagnetic coupling method is used to transmit information between the device and the ground and onboard vehicles.

Command information from the center is transferred to the command transmission position (
For example, from the command information setting console 1 together with the information indicating the ground antenna 8a), irregularly without being restricted in time,
It can be set when the need arises.

The set command information is given to the command information storage device 2 and stored in the memory 3a corresponding to the ground antenna 8a. Command information is issued and transmitted to the CTC station equipment 6 via the L transmission path 5.This command information is
It is registered in the ground transceiver 7a and oscillated to the train 9 via the ground antenna 8a. Note that the ground antenna 8 is installed at a location where command information can be transmitted. Signals oscillated from the ground are received by the on-board transmitting/receiving device 11 via the on-board antenna 10 installed on the train 9, and displayed on the terminal device 12 in the driver's cab to inform the crew of the contents of the command information. can be conveyed.

The answer back check device 22 includes a count start detection device 13, a counter 14, a gate control device 16, a pulse generator 17, and a confirmation signal detection device 18. The arrival of the track circuit is detected when the information on the track circuits 20a and 20b changes from "1" and "0" (20a is on track, 20b is absent) to "1" and "1", and the corresponding ground antenna The command information storage device 2 corresponding to the ground antenna 8a determines whether command information has been given to the ground antenna 8a.
If command information is given, a count start signal is given to the gate control device 16.

The gate control device 16 uses this signal to control the counter 1.
The counter 14 receives the pulse from the pulse generator 17 and updates the count in the register 15a by 11.

When the count of the register 15a exceeds a predetermined count number, a warning or abnormality is displayed on the command information setting console 1 as a timeout of the confirmation signal from the train 9.

A confirmation signal for the command information transmitted on the vehicle is sent to the on-vehicle transceiver device 11 by pressing the confirmation nail on the terminal device 12.
, is oscillated on the ground via the on-board antenna 10, is received by the ground antenna 8a and the ground transceiver 7a, is sent from the CTC station device 6 to the CTC central device 4, and is detected by the confirmation signal detection device 18.

After detecting the confirmation signal, the confirmation signal detection device 18 detects a register 5a in the counter 14 corresponding to the ground antenna 8a.
Gate control device 1 sends a signal to stop updating the count of
6, thereby causing the gate control device 16 to close the gate between the register 5a and the pulse generator 17, and at the same time reset the contents of the register 15a.

Therefore, if the command information is reliably transmitted to the crew and a confirmation signal is returned, no warning or abnormality display will be given. The reset device 19 uses information from the track circuits 20c and 20d to indicate that the train 9 has arrived at a predetermined reset contact point for the ground antenna 8a (for example, the inner track circuit 20d of the in-house signal 21). 1” “0” to “1”
, is detected by changing to "1", and a reset signal is given to the command information storage device 2, thereby resetting the information in the memory 3a corresponding to the ground antenna 8a.

In other words, as mentioned above, when command information is not conveyed to the crew, or when the crew does not issue a confirmation signal, the central dispatcher is notified by an alarm or abnormal display. However, it is also possible to simply reset the command information preset in memory in response to the passing of a train. If the command is not conveyed due to an alarm or abnormal display, it is naturally necessary to take other measures. According to one embodiment of the present invention described above, the dispatcher can set the command information in the central device in advance without considering the timing of command transmission. In this way, it is automatically monitored that the commands are automatically given to the vehicle at the appropriate time and that the commands are reliably transmitted to the crew members, which greatly simplifies the command transmission process. This has the effect of making the transmission of commands more appropriate and reliable.

In addition, the stored command information can be easily reset when the train passes a point, and the memory capacity can be kept to a minimum. FIG. 2 shows another embodiment of the present invention, in which the same parts as in FIG. 1 are designated by the same reference numerals.

The difference from FIG. 1 is that each function of a count start detection device 13, a counter 14, a register 15, a gate control device 16, a pulse generator 17, a confirmation signal detection device 18, and an information reset detection device 19 is performed using a computer 22. It is program-processed and a command information indicator 24 is provided at the platform as a terminal device for transmitting command information.

Furthermore, a typewriter 25 was connected to the computer 22 as a recording device. The computer 22 has a command console 1, a command information storage device 2, a CTC central device 4, and a process input/output device 23.
"Various command information is sent from the command information storage device 2 to the CTC central device 4, the transmission line 5, and the CTC
It is displayed on the command information sign 24 via the station device 6.

The computer 22 is assumed to program and process the same functions as those of the above embodiment. In this embodiment, by installing a timetable rescheduling judgment program in the computer 22, the transmission of various commands related to timetable rescheduling is further automated.Also, by recording the contents of commands and printing them out on the typewriter 25 by the program, the dispatcher can The task of transmitting commands can be greatly reduced.
