Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train operation management device of a centralized type or a train station distributed type, which manages train operation based on display information received from a station or the like, and more particularly to online operation and simulation test in parallel. It is related to the technology performed.

[0002]

2. Description of the Related Art Conventionally, as a device used for a functional test of a train operation management system, training of a dispatcher, etc., the function of a CTC device or an interlocking device is simulated and the train is simulated. A train operation management device including a train operation management device simulation device is known.

FIG. 5 shows a schematic configuration of such a conventional train operation management device. This type of train operation management device 20 includes a central device 1 system 21 for online operation, a central device 2 system 22 for simulation test, a terminal device 23 for performing operation display control on an operation display panel (not shown) or an attached CRT, 24, 25, 26, and a switching device 28 for switching and setting the mode of online operation or simulation test of the central processing unit or terminal device, which are connected via a dedicated optical LAN 27.

First, each terminal device receives the mode information of the terminals 23, 24, 25, and 26 switched and set by the switching device 28 and stores it in the internal memory to set the connection mode. Here, the terminal devices 23 and 25 are set to the online operation mode, and the terminal devices 24 and 26 are set to the simulation test mode. Then, the central processing unit 1 system 21 outputs the train number information based on the train schedule information to each terminal device in order to perform the online operation control, and the terminal devices 23 and 25 conform to the stored connection mode. It judges that the received information is valid and inputs it, and performs the column number display for displaying the train number and the display control for displaying the position of the train in order to monitor the operation status of the train.

However, since the connection modes of the terminal devices 24 and 26 are the simulation mode, the terminal devices 24 and 26 judge that the received information is invalid and do not receive any more. On the other hand, the central processing unit 2 system 22 stores the same train number information and train schedule information as the central processing unit 1 system 21, and at the time of a simulation for performing a functional test of the train operation management device, training of a dispatcher, etc. The train position pseudo information indicating the train position is artificially output to each terminal device, but each terminal device makes the same judgment as described above, and the terminal devices 24 and 26 input the received information and perform the simulation test.

As a result, the test can be conducted in the daytime without occupying the train operation management device in the nighttime and conducting the simulation test, and the test time in the nighttime can be minimized. In addition, since it is possible to easily switch by operating the mode changeover switch, it is possible to improve the efficiency of the test, and in the case of a system that operates 24 hours a day, it is possible to perform the test without stopping the system, thus increasing the operating rate. I was able to improve.

[0007]

By the way, since the above-mentioned conventional train operation management device is a device used in a special field, a dedicated optical LAN is used as a network. Therefore, when expanding or changing the train operation management system, other train operation management systems that use a general commercially available local area network (server / client model) try to perform similar management. However, since the communication procedure is completely different, there is a problem that it is not possible to incorporate the system as it is and it takes time to construct the system.

The present invention has been made in view of the above problems. By using a commercially available local area network and complying with the standard communication procedure of the network, system construction and software introduction of other systems can be easily performed. An object of the present invention is to provide a versatile train operation management device that can be performed.

[0009]

Therefore, according to the present invention, a central processing unit and a plurality of terminal units are connected by a local area network, and the central processing unit comprises an online mode host device and a simulation mode host device. In the train operation management device capable of simultaneously managing the online mode and the simulation mode, a mode switching means for switching and setting the mode of a plurality of terminal devices to the online mode or the simulation mode for each terminal device is provided. The mode storage means for storing the setting mode of each terminal device switched by the mode switching means, and the mode storage means based on the transmission source information included in the transmission information transmitted from each of the terminal devices to the both host devices. The setting mode of each terminal device stored in A mode determination unit that determines whether or not the mode of the device is compatible, and a communication control unit that exchanges data relating to train operation management between the host device and the terminal device that are compatible with the mode by the mode determination unit, respectively. It is configured to have.

Here, the mode storage means may be configured to periodically write each mode of the plurality of terminal devices set by the mode switching means.

[0011]

According to the train operation management device having the above structure, the mode determining means determines the mode compatibility based on the source information from the terminal device received via the local area network, and then the communication control means adapts. By exchanging data between the host device and the terminal device, the server / client, represented by Ethernet,
By applying the model to train operation management, online operation and simulation tests can be performed on multiple devices in parallel.

Further, if the mode storage means is adapted to periodically write each mode of the terminal device set by the mode switching means, even if the user changes the mode setting of the mode switching means, it is immediately The mode can be reflected.

[0013]

[Embodiment] A train operation management apparatus according to this embodiment will be described below. The operation of the terminal itself that controls the central processing unit, the operation display device, and the like in the train operation management system is the same as that of the conventional art, and is therefore omitted, and the differences will be described in detail.

FIG. 1 is a schematic configuration diagram of a train operation management device using an embodiment of the present invention. The central processing unit 10 is a host 1 system 11 as an online mode host device for controlling operation management of online operation, and the host 1 system 11
In place of the above, a host 2 system 12 as a simulation mode host device for pseudo operation management, and a switching device 13 as a mode switching means for allowing these hosts to set the connection mode of the terminal.

A personal computer or a workstation is used for each of the terminals 14, 15 and 16, and the train operation status is displayed on the train operation display device or CRT on the basis of online operation or a simulation test. The central processing unit 10 and each terminal 14, 15, 16 are connected on a commercially available Ethernet 17.

Now, in order to set the terminals 14 and 16 to the online operation mode and to set the terminal 15 to the simulation mode, when the user performs the switching setting with the changeover switch 13a on the switching device 13, the host 1 system 11 Also, the host 2 system 12 reads the setting mode information of the switching device 13 in a cycle of about 1 second and writes it in the mode information memory 18 as an internal mode storing means.

Therefore, even if the user switches the changeover switch 13a, the setting mode is immediately reflected. Although the host 1 system 11 and the host 2 system 12 are already set on the switching device 13 for the online operation and the simulation test, respectively, they can be switched and set similarly to each terminal. The setting modes of the host 1 system 11 and host 2 system 12 and the terminals 14, 15 and 16 are shown in FIG.
It is stored in the mode information memory 18 as shown in FIG.

Next, the transfer of data between the host and the terminal, which is the characteristic feature of the present invention, will be described with reference to FIG. 3 showing a communication control procedure. First, when the terminal side user activates the terminal 14 in the standby state (S1), the terminal 14 sends data to the host 1 system 11 and the host 2 system 12 in accordance with the communication procedure in the Ethernet 17. Request information for requesting is sent (S2).

This request information is received by the host 1 system 11 and the host 2 system 12 via the Ethernet 17 (S
3), each host checks the connection state based on the mode information stored in the mode information memory (S4).
This S4 corresponds to the function as the mode determination means. That is, as shown in FIG. 4, host 1 system 11 and host 2 system 12 are included in transmission information such as request information and notification information described later.
Is included in the destination number, the source number indicating the terminal 14, and control data indicating that the request is a data request to the host. The host 1 system 11 sends the request information from the terminal 14 to the host 1 system 11 or the host. 2 series 12
It can be confirmed that it was issued to. Then, in the mode information of the mode information memory 18, the own mode and the terminal 1
Since it is stored that both modes 4 are the online operation modes, it is determined that the connection is OK, and the processing task 1
9 (S5) and the processing task 19
(S6).

When the processing task 19 creates or selects data to be sent to the terminal 14, the host 1 system 11 inputs the data as sending information and sends it to the terminal 14 via the Ethernet 17 (S7) to link. Establish. This part of S7 corresponds to the function of the communication control means.
Then, the terminal 14 can confirm that a so-called link that establishes a connection state with the host 1 system 11 is established by receiving the transmission information (S8), and notifies the processing task of the terminal 14 to that effect (S9). is there.

On the other hand, the host 2 system 12 receives the request information and confirms that it is the information transmitted from the terminal 14. However, in the mode information, the self mode is the simulation test mode, and the terminal 14 Is stored in the online operation mode, the connection N
It is judged as G (S4), and the terminal 1 is sent via the Ethernet 17.
The NG answer is returned to No. 4 (S7). By receiving the NG answer (S8), the terminal 14 can confirm that the so-called link that is in the disconnected state with the host 2 system 12 has been stopped.

Thereafter, the terminals 15 and 16 are also controlled in the same manner to establish a predetermined link so that the host 1 system 11 and the terminals 14 and 16 can be operated online at the same time as the host 2 system 12 at the same time. And the terminal 15 performs a simulation test. Further, when data is to be transmitted from the terminal side, notification information indicating data transmission to the host is set in the control data in the transmission information shown in FIG. 4, and the transmission data is added and transmitted. The communication control similar to the above is performed on the terminal side and the host side, and the predetermined host can receive the data.

If the host determines that the connection is OK at the time of checking the connection state, the OK answer may be returned and then the transmission information may be transmitted. In this way, for the request information or notification information transmitted from the terminal device via a commercially available local area network such as Ethernet,
