Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train operation management system for performing centralized monitoring control of train operation.

[0002]

2. Description of the Related Art A train operation management system is used for the purpose of sophistication and rationalization of train operation handling and related operations.
It is a system that centrally monitors and controls train operation based on the schedule created in the transportation plan.

Since this train operation management system is positioned as a development of the centralized control system for trains, its central function is usually centralized in the central command station. The control device such as a computer at the central command station and the control device for the calculation function at each station are connected via a transmission line so that data can be transmitted between the central command station and each station, or between each station. It has become.

By the way, the train operation management system is required to have a high degree of reliability because it controls a public transportation system called a railway. To meet this demand,
Conventionally, reliability has been ensured by, for example, multiplexing computers in a central command center.

Alternatively, in addition to disposing the control devices in each station where monitoring control is required, only centralized monitoring is performed at the central command station, and in the unlikely event that an abnormality occurs in the control device in the central command station. However, a so-called regional distributed management system in which the control device of each station continues the monitoring control has also been introduced.

[0006]

However, in the case of a system in which the computers in the central command center are multiplexed, if a malfunction occurs in this multiplexed computer, all functions as a train operation management system will be lost. This will have a great impact on train operation.

Further, in the case of the regional distributed management system, the computers at each station, which require monitoring and control, must be multiplexed, which is very disadvantageous in terms of cost.

The present invention has been made in view of the above circumstances, and provides a train operation management system capable of ensuring high reliability equivalent to that of a regional distributed management system without increasing costs. The purpose is to

[0009]

As a means for solving the above problems, the present invention connects a control device in a central command center and each control device in a plurality of stations to a transmission line,
In the train operation management system for transmitting data between this command station and each station, or between each station, the control device in each station has its own station information processing means and other station information processing means. It is also characterized in that, when an abnormality occurs in the control device of one of the stations, the function of the control device of that station is replaced by the control device of another station. ..

[0010]

In the above structure, normally, the control device in each station executes the processing relating to its own station by the information processing means for its own station based on the information received from the central command station or from the outside.

At this time, the received information is also received by the information processing means for itself (information processing means for another station when viewed from the other station) provided for the control device in the other station. The same process is performed.

As described above, since each station has the information processing means for performing its own processing in the other stations, even if an abnormality occurs in the control device of its own station, the other station With the information processing means for self provided inside, it is possible to maintain the same information processing operations as in normal times.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In this figure, a central command station 1Z includes a computer 2Z having an object 3Z that executes a monitoring function in the command station, a local management unit 4Z, and a man-machine interface 5Z including a keyboard and a display unit. It is provided.

In the station 1A, a computer 2A having an object 3A which is an information processing means for its own station, an object 3B which is an information processing means for another station, and a local management section 4A, and monitoring control information are stored. Input / output device 6A for input / output and external device 7A such as interlocking device
And are provided. The stations 1B and 1C have the same configuration. And these central command station 1Z and stations 1A, 1
B and 1C are connected to the transmission line 8 so that data can be transmitted between them.

The above-mentioned computers 1A, 1B, 1C and 1Z employ well-known object models, and the objects 3A, 3B, 3C and 3Z are data required for their own processing and application programs capable of autonomous operation. Is included.

The local management units 4A, 4B, 4C,
The 4Z is for managing the processor and memory of each computer, and for sending and receiving messages.

Next, the operation of this embodiment configured as described above will be described. For example, considering the station 1A, the input / output device 6A broadcasts information input from the external device 7A to all the computers 1B, 1C, 1Z via the transmission path 8. The object in charge of inputting the information in the object 3A analyzes the content of the information, and the object in charge of output outputs the result to the computer 2 in which it exists.
Not only A but also the object 3A existing in another computer 2C is broadcast-communicated via the local management units 4A and 4C and the transmission path 8.

The object 3A in each of the computers 2A and 2C which has received the information analyzes the content, executes the process if it should be processed by itself, and outputs the result to all other objects 3A ( In this case, computer 2A, 2
Broadcast to each other's object 3A) in C. In executing this process, object 3
A does not refer to the data in the other object 3A, and performs processing only by the data contained in itself. Of course, computers 2A, 2B, 2
In C, there is no such thing as a data file referenced by the object 3A.

Although the above is for the object 3A, the objects 3B, 3 at the stations 1B, 1C are
The same applies to C.

By thus judging that each object is a matter to be processed by itself and broadcasting the execution result of the processing to all the other objects, the functions of each station can be changed by cooperation between the objects. It is also realized at the station.

Therefore, for example, the computer 2 in the station 1A
Even if an abnormality occurs in A, the processing for station 1A is
Object 3A provided on computer 2C at station 1C
Since it can be replaced by, no trouble will occur. In the conventional regional distributed management system, reliability must be ensured by arranging two or more computers 2A in the station 1A and multiplexing them, but according to the present invention,
It suffices to arrange only one computer 2A having a plurality of objects. In other words, it is possible to ensure the same level of reliability as the conventional regional distributed management system without inviting an increase in cost.

In the above embodiment, there is no management mechanism for centrally performing global operation management such as load management of objects, concurrency control, and failure management. These functions are distributed among individual objects. It is implemented by the cooperation of each object.

In the above embodiment, each object has only two stations (for example, the object 3A has stations 1A and 1A).
It is provided in C only), but of course, the present invention is not limited to this and may be provided in all stations.

[0024]

As described above, according to the present invention, the control device in each station has the information processing means for its own station and also the information processing means for another station. When an abnormality occurs in the control device of a station, the function of the control device of that station is replaced by the control device of another station, so that regional distributed management can be performed without increasing costs. It is possible to secure the same high reliability as the system.
