Description

[Detailed Description of the Invention] This invention relates to an operation display panel in a train operation control device that displays the operation status of a train based on display information that is transmitted and concentrated from each end of a CTC (train central control device) to the center. This relates to the display method.

The train operation control device transmits display information from terminals installed in each section to the center, and also includes an information transmission device that transmits control information from the center to each terminal, train detection information, and train detection information among the display information transmitted from the terminals. It consists of an operation display panel that displays the operation status by train position and train number based on route information, etc., and is usually used in conjunction with CTC, so the information transmission device is shared with CTC. Ru. and,
Each time train detection information is input from each terminal, the display contents of the display area corresponding to the relevant detection section on the operation display board are sequentially shifted according to a predetermined program.

However, in conventional train operation control devices, if a part of the transmission system, such as the terminal device of the information transmission device or the terminal corresponding part of the central device, breaks down and there is no trace of information input from the terminal, the operation display panel will fail. The display area corresponding to the occurrence section will be completely blank.
The drawback was that the operating status could not be determined.

This invention was made in view of the above,
The purpose of this system is to enable, even if a failure occurs in a part of the transmission system, the operation status of the train almost identical to the actual operation to be displayed on the display panel through the operation of the central information processing unit until the failure is recovered. .

Next, one embodiment of the present invention will be described with reference to the drawings. Figure 1 shows the train central control system (CTC)
FIG. 2 is a block diagram schematically showing the configuration of a train operation control device added to the train operation control device.

a ₁ , a ₂ to a _o are terminal-side information transmission devices installed at each station or each section, and each is a relay interlock device.
connected to b ₁ , b ₂ ~ b _o and train detectors c ₁ , c ₂ ~ _{c o} ,
Normally, traffic lights, track circuits, etc. every 2 to 3 seconds.
The CTC display information is transmitted to the central information transmission device _a0 installed in the center, and is input to the central information processing device e via the input/output device d by an interrupt signal.

The central information processing unit e operates signals and switches based on the CTC display information and predetermined train operation schedule transmitted centrally from each terminal, or based on commands input from the operation panel f connected to the central information processing unit. CTC control information regarding the lever is output, transmitted from the central information transmission device a ₀ to the terminal information transmission device (any one of a ₁ to a _o ) of the relevant track section, and relay interlocking device (b ₁ to a b ₎ to operate the train under the operating conditions according to the train operation schedule.

In addition, based on the display information transmitted from each terminal, the train position and train number are displayed on the display section corresponding to each track section of the operation display panel g to display the operation status, and the observer can display the operation status. The operating status of each train can be monitored from panel g.

FIG. 2 is a block diagram showing the configuration of only the portion of the central information processing unit e used for displaying on the operation display panel g according to the method of this invention. The central information processing unit is connected to each terminal side information transmission device a ₁ , a ₁ to a _o , each terminal corresponding part of the central side information transmission device a ₀ , and the transmission system such as the communication line connecting each terminal and the center. If there is no failure that would prevent information from being input to e, the normality detection unit 1 installed in the central information processing unit e operates based on the train detection information among the displayed information from each terminal. do. The normality detection unit 1 is composed of detection elements corresponding to each terminal, and each detection element generates a detection signal every time train detection information from the terminal is input. A normal shift section 2 is connected to the normality detection section. The normal shift section shifts the contents of the register corresponding to each display window of the operation display panel g of the display storage section 3 every time it receives a detection signal from each of the detection elements. The display storage section 3 has registers corresponding to display windows corresponding to each terminal of the operation display board g. Train number storage section 4
is provided with a memory corresponding to each of the display windows, and each memory stores display contents (train numbers) in accordance with the order of the train operation diagram for the track section displayed by the corresponding display window.

When the normal shift section 2 generates a shift condition, the next train number is rewritten from the corresponding memory of the train number storage section 4 to the corresponding register of the display storage section 3, and the display contents are shifted. The display section 5 reads the contents of each register in the display storage section by scanning, and displays the train number on the display window corresponding to each register on the operation display panel g.

Figure 3 shows the main parts of the operation display corresponding to the three track sections 1T to 3T of the line. The central information transmission devices a ₁ to a ₃ installed in each section receive signals from the relay interlocking devices b ₁ to b ₃ and train detectors c ₁ to c ₃ installed at multiple points in the section. The display information output by each of the terminal side information transmission devices a ₁ to a ₃ is given to the central information processing device e via the central side information transmission device a ₀ and the input/output device d. On the operation display board g, there is a route map Rd that approximates the above route R,
Required number of display windows between each section 1T to 3T w ₁ ~
_w8 is placed.

In this way, if there is no failure in any of the transmission systems, the display information transmitted from each terminal is displayed on the operation display panel g, and at the same time as the train approaches in each section 1T to 3T, the operation by the normal shift section 2 is activated. , the train number is displayed in the display window corresponding to each section, and as the train progresses, the display contents in each display window are sequentially changed.

On the other hand, when a part of the transmission system breaks down and there is no trace of information input from any terminal, the fault detection section 6 provided in the central information processing unit e detects the occurrence of the fault. . The failure detection unit 6 constantly monitors information from each terminal, and when information from any terminal is not input continuously for a predetermined period of time or more, it determines that a failure has occurred in the information transmission device on that terminal side, and automatically starts the next stage. Start the shift section 7. The automatic shift section 7 can perform an automatic shift operation corresponding to each register of the display storage section 3, and when a failure occurs,
Until the failure is recovered, the section where the failure occurred (hereinafter referred to as
A counter corresponding to the operating time interval (travel time) of the train operation schedule in the fault section is set, and each time the counter counts up, a shift condition is generated and a corresponding display is displayed in the display window of the fault section. The contents of the register in the storage section 3 are shifted.

For example, if a failure occurs in the transmission system corresponding to section 2T in Figure 3, a counter is set corresponding to the operating time interval of the train schedule in that section 2T, and the shift condition is set when the predetermined time counts up. Since it is given to a predetermined register in the display storage section, the display contents of the display windows w ₄ to w ₈ in the section 2T are sequentially shifted.

Therefore, even if the display information for a certain section cannot be input due to a partial failure in the transmission system, the automatic shift unit 7 activated by the failure detection will shift the display information based on the train operation schedule from the time the failure occurs until recovery. The operating status is displayed at display locations corresponding to the faulty section at time intervals. That is, the display contents are shifted at intervals equal to the train operation schedule (travel time).

Next, when the train moves from the faulty section to the normal section, the transmission system corresponding to the normal section transmits the train detection signal to the center when the train enters the normal section, so the central information processing unit's normal shift The display contents are shifted by the operation of section 2. That is, when a train moves from a faulty section to a normal section, the display content (train number) that has been shifted to the last display window of the faulty section is shifted to the normal section according to the shift conditions of the normal section.

In Figure 3, when a train enters the next normal section 3T from the faulty section 2T, based on the input of the train detection signal from the first train detector _c3 in that section, the train detects the section 2T on the operation display panel g. The display contents of the display window _w6 are shifted to the first display window _w7 of the section 3T.

The failure detection unit 6 has a function of storing information for each terminal when a failure that makes information transmission impossible occurs in the transmission system, and each failure occurrence storage signal is given to the recovery detection unit 8. The recovery detection unit monitors the presence or absence of information input each time an interrupt signal is input from the central information transmission device _a0 , and detects whether information has been input and the failure detection unit 6 detects information about the terminal. When the failure occurrence memory signal and the AND condition are satisfied, it is detected that the failure has been recovered. That is, when the failure is actually recovered and information is input again, it is determined that the failure has been recovered, and a recovery detection signal is given to the automatic shift unit 7 to stop the automatic shift of the display contents by the automatic shift unit. When failure recovery is detected, the failure detection unit 6 receives a recovery detection signal.
Reset the failure occurrence memory.

When a train changes course in a faulty section, it is desirable to be able to display information on the display panel that corresponds to the actual operating conditions. In order to meet this demand, the display contents can be manually changed to a predetermined course (display window).
A manual shift section 9 is provided so that the display window can be shifted to a display window for a different route. To perform manual shifting, press train number shift button 1 on operation panel f.
After depressing 0, use the numeric key 11 to shift the tenth digit that specifies the display window containing the train number,
A number consisting of two digits including the first digit that designates the display window to which the shift is to be made is input, and the number is given to the manual shift section 9. The manual shift section 9 is the display storage section 3
Shifts the display contents of the display window specified by the tens digit number from the corresponding register to the display window specified by the ones digit number. In order to deal with the occurrence of two or more failures in the transmission system, a station name button 12 is provided on the operation panel f, and by operating the train number shift button 10, station name button 12, and number key 11 in this order, each Display contents can be manually shifted for each failure section.

A manual display shift instruction is performed in the following cases. In other words, when a failure occurs, when the train number is displayed at a location other than the location determined by the computer (passing on the main line), and when the train is displayed on a route other than the determined route, i.e., the warehousing route, exit route, intermediate track, This is the time to travel on a turning route.

In CTC, if display information from a certain station is no longer input, the central information processing unit e will no longer be able to perform all functions such as train tracking, route control, and judgment for that station.

If a failure like the one above occurs in a part of the CTC transmission system, computer control of the station and adjacent stations will become impossible, so if the failure lasts for a long time, the control of the station will be treated as a station. It is necessary to Therefore, the control panel f is constructed so that, based on a transmission system failure, it is possible to change the faulty section from computer control to CTC central handling, and further to station handling. When the CTC malfunctions, the station manually switches the system to station status, so as not to affect train operation.

In other words, for the relay interlocking devices b ₁ to b _o in each section, a control panel is installed at each station, and the control mode can be controlled by computer control, CTC central control, or station control by mode switching commands from the central operation panel f. can be changed in this order or in the reverse order, and normally the above relay interlocking device is controlled by a computer using the CTC display information, but if it is treated as a station, it can be changed by using a lever on the control panel of the station. Train operating conditions can be set to regular operating conditions or temporary operating conditions by driving signals and switches.

In this invention, in a faulty section, the relay interlocking device for that section is handled at the station to perform control to ensure that the train operates according to the train schedule.

Therefore, the display window corresponding to the faulty section of the operation display panel g will also display an operation display that is almost the same as the actual operation status.

Next, based on the above configuration, a series of operations from the time when a failure occurs in a part of the transmission system in the CTC until recovery will be explained.

When there is no input of reports for all stations for a certain period of time or more due to a failure of the CTC at the relevant station, the failure detection unit 6 determines that a failure has occurred for the relevant station. The central information processing unit e displays the fact that an abnormality has occurred on a character display (not shown), operates the automatic shift unit 7, and changes the display contents of the display window corresponding to the faulty section (station) to indicate that the abnormality has occurred. The display contents immediately before the occurrence of the fault are automatically shifted at regular intervals according to the train operation schedule in the faulty section, and the train number is displayed and shifted in a pseudo manner for the faulty section. In this case, in the faulty section, the train will be treated as a station and operation will continue under the operating conditions as per the timetable. Therefore, the operation display panel displays a display that corresponds to the actual operation status.

The display and shifting of train numbers for trains that enter the faulty section during a fault and for trains that proceed from the same section to a normal section are performed based on display information transmitted from adjacent stations. On the other hand, for trains within the faulty section, the train number is displayed at regular intervals according to the train operation schedule by the automatic shift unit 7, as described above, for trains on a determined route (main line). and shift. In addition, for vehicles traveling on routes other than the determined route (entering/exiting routes, turning lines, intermediate lines), a manual shift instruction is given via the operation panel f and the manual shift section 9. The range in which manual shifting can be performed is
These are only the parts related to the station's platform track circuit.

In addition, in order to display the next running train number of the return train, it is necessary to correct the train number. In order to do this, a train number correction button 13 is provided on the operation panel f, and after pressing it down, input the code specifying the display window, and then input the train number to be changed. The train number displayed on the designated display window is changed to the designated train number.

The transmission system in the faulty section is restored, the CTC at the station is restored, and the display information for that station is updated to the central information processing unit e.
When the input is made, the recovery detection unit 8 operates,
It is determined that the CTC failure has been recovered, and a message to that effect is displayed on the character display. Then, all train numbers corresponding to the section that were displayed during the failure are erased, and a temporary train number for the section is assigned and displayed based on the CTC display information. The watchman manually makes the correction to the true train number using the operation panel f.

If multiple trains are displayed in the faulty section,
How to manually correct all temporary train numbers,
There is a method of manually correcting only the initial temporary train number, and then automatically correcting the actual train number for each failed section when one train passes in each direction.

Regarding the relationship between the CTC and the operation display, in addition to the operations described above, the following operations are performed to shift the handling mode when recovering from a failure. In other words, after the train staff confirms the train number after the failure is recovered, the train is no longer handled by the station.
CTC central handling, change from CTC central handling to computer control. Train numbers and computer control will also be changed for adjacent stations.

As described above, according to the present invention, if there is no failure at all in the transmission system, the operation display panel displays the operation display and shifts the display contents to match the actual operation status based on the transmitted CTC display information. done,
In addition, if a partial failure occurs in the transmission system, until the failure is recovered, trains will be operated under the operating conditions according to the train schedule set by the station in that failed section, and based on the train operation schedule for the failed section. Since the display contents are automatically shifted at the time interval, it is possible to display the operation status almost the same as the actual operation status even in the faulty section.

Conventionally, when a failure occurs, there is no display for that section at all, making it impossible to know the operating status, making it impossible to issue driving commands from the operation panel, or causing errors in operation monitoring using the operation display panel. However, when the method of the present invention is used, the above-mentioned drawbacks can be solved and safe operation management can be performed because the display is almost realistic even if it is pseudo.
