Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a distributed train operation control system, and in particular, to a system for reliably preventing the central system from stopping functioning even if a part of the processing system malfunctions. This relates to a system configuration that avoids problems and improves reliability.

[Prior Art] This type of distributed train operation management device generally has the following features:
It consists of a central device installed at the central control center, station processing devices installed at each station, and loop transmission lines connecting the central device and each station processing device. The central unit manages all train operations from a central location and can also perform manual control. The loop transmission line is
All train information from the central device is transmitted to each station processing device, etc., and information from each station processing device, etc. is transmitted to the central device. The station processing device temporarily stores all train information received via the loop transmission line, and controls facilities such as the station premises and trains entering or departing the station according to the stored contents.

Examples of conventional distributed train operation management devices include Japanese Patent Publication No. 39-12962 and Japanese Patent Publication No. 12962-1973.
There are publications such as No. 8203.

[Problems to be Solved by the Invention] In the above-mentioned distributed train operation management system, the central unit includes a higher-level central processing unit that manages the operation of all trains, and a lower-level central control unit that performs manual control, display control, etc. The upper central processing unit was connected to the loop transmission line via the lower central processing unit. Therefore, when the central processing unit fails, a situation occurs in which the central processing unit becomes isolated. As a result, there was a problem in that the central device stopped all functions.

An object of the present invention is to provide an inexpensive distributed train operation management system that improves reliability by reliably avoiding a situation in which the central unit stops all functions even if a lower central control processing unit fails. It is.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a central device installed in a central command center that manages the operation of all trains and can manually control all trains from the center; A transmission line that transmits train information to each station processing device, etc., and transmits information from each station processing device, etc. to the central device, and a transmission line that temporarily stores train information received via the transmission line and stores the train information according to the stored content. It is a distributed train operation management system consisting of station equipment, etc., and a station processing device that controls trains entering or departing from the station, and the central device has a display means for displaying the train position and a transmission line. A central control processing unit that is directly connected to the system allows train operation instructions to be input manually and displays train positions on display means based on train position information from the station processing unit, and a central control processing unit that is directly connected to a transmission line that allows train operation instructions to be input manually and that displays train positions on display means based on train position information from the station processing unit. a central processing unit that manages operation and displays train positions on a display means based on train position information from each station processing unit; and a switching device that selectively connects the central control processing unit and the central processing unit to the display means. The present invention proposes a distributed train operation management device in which the switching device normally connects the display means to the central control processing unit, and switches and connects the display means to the central processing unit in response to a failure signal from the central control processing unit. be.

[Function] When distributed train operation management equipment was first put into practical use, the central processing unit
It was connected to each station's processing equipment to perform operation management and train tracking.

However, if an abnormality occurs in the central processing unit, it will interfere with train operation management, so a central control processing unit as a manual backup system is installed between the central processing unit and the loop transmission line, and the display means is centrally operated. I decided to connect it to the control processing unit. This is because even if the central processing unit is a dual system or a triple system, safety effects can be expected, but the system becomes larger and costs increase.

However, if the central control processing unit, which is the backup system, breaks down, the data transmission and display functions between the station processing unit and the central processing unit will be impaired, causing the problem that all operation management will stop. Ta.

Therefore, in the present invention, the central control processing unit and the central processing unit are each directly connected to the loop transmission line, and the display means is normally connected to the central control processing unit side, but in the event of a failure of the central control processing unit, It is now possible to switch and connect to the central processing unit. Further, when both processing devices are in a normal state, the display means may be connected to either side according to an operator's command.

If such a configuration is adopted, if the automatic control system, that is, the central processing unit fails, the train operation can be managed manually. On the other hand, if the manual operation management system, that is, the central control processing unit, fails, the train operation can be managed automatically without impairing the data transmission function and display function between the station processing unit and the central processing unit. Furthermore, compared to a system in which the central processing unit is a dual system or a triple system, the system can be constructed at a lower cost.

The central control processing unit has a function of manually inputting train operation instructions and a function of displaying the train position on the display means based on the train position information from the station processing unit.

The central processing unit has a function of managing the schedule of all trains operating on the day and monitoring the operation of all trains, and a function of displaying the train position on the display means based on the train position information from the station processing unit.

[Example] Next, an example of the present invention will be described with reference to the drawings, but before that, a conventional example that is the starting point of the present invention will be described.

FIG. 1 is a block diagram showing an example of the configuration of a conventional distributed train vehicle operation management system, which is the starting point of the present invention.

In FIG. 1, the central device 1 includes a central control processing device 13 and a central processing device 15. As shown in FIG. The central control processing unit 13 manages the operation of all trains and can also perform manual route control based on information manually input from the central route setting console 12. The central processing unit 15 manages all train schedules operating on the day, manages the operation of all trains, creates operation performance statistics, and sends them to the printing device 14 for recording. Note that the central processing unit 15 can be operated by an operation console 16.

The central device 1 is connected to the loop transmission line 3 via the transmission device 2P, and sends out all train information to the loop transmission line 3.

The loop transmission line 3 includes transmission devices 2A, 2B,
. . , 2N are connected to station processing devices 4A, 4B, . . . , 4N provided at each station. The station processing devices 4A, 4B,..., 4N are connected to the loop transmission line 3.
Only the necessary information is captured from the information transmitted to the system.

Each station processing device 4A, 4B,..., 4N includes a relay interlocking device 5A, 5B,..., 5N, a guidance public relations device 6A, 6B,..., 6N, and a train number detection device 7.
A, 7B, . . . , 7N are connected to each other. The station processing device 4, via the relay interlocking device 5,
Track information and signal information are taken in and transmitted along with train tracking information to the central device 1 via the loop transmission line 3.

In the conventional distributed train operation management device configured in this way, the central processing unit 15 usually
Train information for a certain period after that time is sent in advance to the station processing devices 4A, 4B, . . . , 4N at each station. Each station processing device 4A, 4B, . . . , 4N manages equipment in the station premises and the operation of trains entering or departing from the station based on the train information. On the other hand, from each station processing device 4A, 4B,..., 4N,
At fixed time intervals, train information for a fixed period after that time is transferred.

The central control processing unit 13 displays the train operating status on the display means 1 based on the information transmitted from the station processing unit 4.
1 and transmits the information manually set on the central route setting console 12 to each station processing device 4A, 4B, . . . , 4N.

In this way, even if the central device 1 fails, the train operation status can be ensured for a certain period of time. Also,
The station processing device 4 does not need to store all train information, which has the advantage of reducing its burden.

However, if the central control processing unit 13 at the lower level fails, the central processing unit 15 at the higher level becomes isolated, and therefore all functions of the central unit 1 actually stop.

As a countermeasure to this problem, methods have been proposed in which the central processing unit 15 and the central processing control unit 13 are multiplexed, or only the lower central processing control unit 13 is multiplexed to improve reliability. It also had the disadvantage of increasing costs.

FIG. 2 is a block diagram showing the system configuration of an embodiment of the distributed train operation management system according to the present invention. In FIG. 2, parts that perform the same functions as those in FIG. 1 are given the same reference numerals, and their explanations will be omitted.

This embodiment is different from the conventional example shown in FIG. The point is that a switching device 17 is provided which connects to either one of the devices 15 and displays the contents of either one.

In this case, the central processing unit 15 needs to have some of the functions of the central control processing unit 13 redundantly, but the increase is small.

In this embodiment having such a configuration, the station processing device 4 transmits the train tracking information that it is tracking and the train position information, signal information, etc. taken in from the relay interlocking device 5 to the loop transmission line 3. send to. Central control processing unit 13 and central processing unit 15
This means that these pieces of information are taken in from the loop transmission line 3 substantially simultaneously.

When the central control processing unit 13 is normal, the switching device 17 is connected to the central control processing unit 13, so the central control processing unit 13 causes the display means 11 to display the operating status.

On the other hand, when the central control processing unit 13 fails, the switching device 17
The display means 11 is switched and connected to the central processing unit 15 side in response to a failure signal S from the central processing unit 15. Therefore, the central processing unit 15 causes the display means 11 to display the operating status.

Of course, if necessary, the central manual setting console 12
Alternatively, a configuration may be adopted in which connection is switched to the central processing unit 15. However, automatic operation management using the timetable of the central processing unit 15 is possible even without such a circuit configuration.

According to this embodiment, a highly reliable and inexpensive distributed train operation management system can be realized without duplicating the central processing unit 13.

Note that although the transmission line has been explained here as being limited to a loop transmission line, it will be obvious that the present invention can also be applied to a distributed train operation management system that employs other types of transmission lines.

[Effects of the Invention] According to the present invention, the central processing control unit and the central processing unit are directly connected to the transmission line so that information can be exchanged, so even if the central processing unit fails, the central processing unit remains functional. This provides an inexpensive distributed train operation control system that reliably avoids situations where trains are stopped and improves reliability.
