2. Description of the Related Art Conventionally, a train number processing device incorporated in a CTC central unit tracks (shifts) train number (column number) information transmitted from a site via a CTC line using a processor having a hardware configuration. Processing), and the result is sent to a train operation management device (for example, a ComTrack system) as a higher-level device.

As described above, the train operation management device executes the management of the train operation on the basis of the result of the shift processing, so that high reliability is required for the column number processing. The configuration of the hardware for performing the shift processing is a triple system configuration, and the shift processing is performed by the 2 out of 3 system.

[0004]

However, the conventional train number processing device described above has a hardware structure of a triple system, and thus has the disadvantage of increasing the size of the equipment housing and making it impossible to use a mother boat. However, there is a disadvantage that the design cost and the manufacturing cost are increased. Further, it is difficult to establish a communication network by optical communication or the like, which is inconvenient in constructing a train control system.

Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to reduce the hardware by adopting software processing, thereby achieving miniaturization and networking. An object of the present invention is to provide a train number processing device which is enabled.

[0006]

In order to achieve the above object, a train number processing apparatus according to the present invention performs arithmetic processing on input train number information using a predetermined train tracking processing program, and inputs the information. First track calculation processing means for tracking the train corresponding to the given train number, and the same train tracking processing as the predetermined train tracking processing program used in the first track calculation processing means for inputting the train number information. A second tracking calculation processing means for performing calculation processing using the program to track a train corresponding to the input train number; a tracking state of the train obtained from the first tracking calculation processing means; A matching means for matching the tracking state of the train obtained from the tracking processing calculating means, and an output means for outputting the obtained tracking state of the train when a matching match is obtained. Further, the train number processing device is characterized in that a main system and a sub system are duplexed.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a train number processing device according to one embodiment.

[0008] The train number processing device a is configured to have a dual system of a master system (A) and a slave system (B). Both systems (A, B)
Are configured identically, so that the main system (A)
This will be mainly described. When the driving of the main system (A) is stopped, the sub system (B) becomes the main system, and the main system (A) up to that becomes the sub system. Thus, both are positioned at the same level.

The CPU 1 controls the main system A as a whole, and also serves as a collating means of the present invention. The CPU 1 has a pair of tracking processing CPUs corresponding to the first and second tracking calculation processing stages of the present invention via the bus line L.
2a, 2b, an input I / F 3 and a column number display driver 4 are connected.

The tracing process CPU 2a uses a train tracing process program stored in a memory (not shown) to perform an arithmetic process for tracing the position of the train corresponding to the column number information input via the input I / F3. Is configured to do so.

The tracking processing CPU 2b is stored in a memory (not shown). Using the same train tracking processing program as that stored in the tracking processing CPU 2a, a calculation processing for tracking the position of the train related to the column number information input via the input I / F 3 is performed. ing.

As described above, the two tracking processing CPUs 2a and 2b
Adopts a configuration in which the same column number information is processed in parallel by using exactly the same train tracking processing program.

The column number information input to the input I / F 3 is, like the well-known column number information, transmitted from the vehicle (train) to the ground or from a column number reading device provided on the ground. It is obtained.

The row number display driver 4 forms a part of the output means of the present invention, and is provided with a row number display unit 6 provided on an operation display panel 5 provided in a CTC central unit or the like to be described later.
Is configured to be able to display the column number.

Although only one column number display 6 is shown here to omit the drawing, in actuality, a large number of column number displays 6 are provided at predetermined locations on the route map displayed on the operation display panel. It is provided so that the moving state of the train of a specific row number can be understood.

Although a watchdog timer and the like are connected to the bus line L, they are omitted because they are not particularly necessary for the description of the present invention.

Next, the control operation will be described with reference to the flowchart of FIG. It is assumed that the main system (A) is operating normally.

When column number information is input via the input I / F 3 (Yes at Step 100; hereinafter, the step is referred to as "S"), the column number information is used for both tracking processing CPUs 2a and 2b.
Is stored and stored in a memory (not shown) (S10).
2).

The two tracking processing CPUs 2a and 2b execute the arithmetic processing on the acquired column number information using the same train tracking processing program (S104a and S104b).
The calculation results of the two tracking processing CPUs 2a and 2b are collated by the CPU 1 (S106). If the collations match (Yes at S108), the results are sent to the operation display board 5 via the column number display driver 4 (S110). .

When the collation does not match (No at S108), an abnormal process is performed, and the cause is displayed on a failure display (not shown).

The column number display 6 of the operation display panel 5 displays the column number (“0122” in the example of FIG. 1) of the train according to the column number information of the above-mentioned matching check. In addition, this column number is subjected to the same processing as the above-described arithmetic processing according to the movement of the train, and then shifted and displayed on another column number display 6.

The above-mentioned collation-matched column number information is transmitted to the operation display panel 5 for display.
It can also be sent to other processing devices.

The above control operation is performed in the case of the main system (A). However, the same operation is performed when the sub system (B) becomes the main system, and the train operation is ensured.

Since the train number display device a having the above configuration employs software processing, the overall configuration can be reduced in size, the motherboard can be easily formed, and the communication control unit can be added to enable communication. Network (L
AN) can be easily constructed.
