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 capable of simplifying version management by making the versions of a control program and a database common within the range of the train operation management system, a storage medium used therein, and The present invention relates to a train operation management device setting method.

[0002]

2. Description of the Related Art A train operation management device is generally installed at each station to be controlled, and a master of its control program and database is composed of programs and databases common to each station and programs and databases unique to each station. It is managed for each target station and for each function. Further, a version for determining the update time is uniquely set in these control programs and databases. This version is checked at the time of shipment of the train operation management device at each station and at the time of software modification, and the same contents as the master are installed in the storage medium held by each station train operation management device.

When the control program and database of the train operation management device in operation installed in a station are modified and upgraded, or when a newly created train operation management database is installed, the following ( Repair according to the procedure from 1) to (4). (1) Stop the system. (2) Using another storage medium (floppy (registered trademark) disk or the like), start up a utility dedicated to the installation of the control program and the database. (3) Install all or the difference of control software by overwriting. (4) Start up the system.

Since it is inefficient to subdivide the control software and store it in different media, the programs and databases of the train operation management devices at a plurality of stations may be collected and stored in one medium. In this case as well, when installing the program and database, the operations (1) to (4) are similarly performed to select and install the program and database of the target station.

Further, as described in Japanese Patent Application Laid-Open No. 2000-311080, in a general computer system, in response to a request for saving an operating environment from a user, some or all of a plurality of operating environment setting items are set. The environment saving means that acquires the setting information corresponding to each operating environment setting item from the environment setting information, and saves the acquired environment setting information in a batch, and saves it in the environment saving means in response to the operation environment switching request from the user. It is disclosed that the contents of the environment setting information are reset by using the set information that has been set.

[0006]

In the conventional train operation management device described above, the number of stations in which the train operation management device is installed is recorded because the control program and database for each station or the type of control data is recorded in the storage medium. Also, as the number of types of data increases, the number of storage media to be managed also increases. These control storage media are strict version control in order to prevent degradation when software is modified, that is, to prevent programs and databases of older versions than the current ones from being accidentally installed in the storage media owned by the train operation management device. is necessary. However, as the number of recording media increases, version differences between storage media are likely to occur, so version management in the entire train operation management system becomes complicated and complicated, and the cost of maintaining versions increases. is there.

Further, when a manufacturer developing control software conducts a test by using a train operation management device, a train operation management device of one station is operated by a train operation management device of another station during the test as a train operation management system. When testing as a management device, a program and a database must be installed and reset every time, using a control storage medium for another station, in the storage medium or storage device inside the train operation management device.

Further, in the computer system setting method disclosed in Japanese Unexamined Patent Publication No. 2000-311080, the environment setting information individually stored by the user cannot be provided to a plurality of computers on the network at the same time.

A first object of the present invention is to simplify the version management by making the versions of the control program and the database common within the train operation management system range.

A second object of the present invention is to develop a program and database for controlling the train operation management device by installing the common program and database in the train operation management device of the station to be operated. The purpose of this is to eliminate the waste of repeating the work of installing the program and the database in order to make settings for other stations when the manufacturer conducts the test, and to perform the test efficiently.

A third object of the present invention is to enable simultaneous repair of a storage medium or a storage device of a train operation management device at a plurality of stations by remote control.

[0012]

[Means for Solving the Problems] The first and third objects of the present invention are, of the control programs and databases of the train operation management device, the programs and databases common to the train operation management system, which are stored in a storage medium without duplication. The individual programs and databases for each station that cannot be saved and shared can be realized by recording them in different areas of the same medium.

The second purpose is to install a program and a database which are shared by the train operation management system in the train operation management device and determine which station the train operation management device has the system function. It is realized by automatically setting the train operation management device by expanding the program and data of the train operation management device selected and activated by the selection setting function in the operation storage area inside the train operation management device.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings, taking a train operation management device installed at each station as an example.

FIG. 1 is a block diagram of a train operation management system in the embodiment. The train operation management devices 1 and 2 installed in the station are stored in a CPU unit 101, a main storage device 103, an internal storage device 104 (which may be the internal storage device 104) for storing programs and data, and an internal storage device 104. It is composed of an associated station setting mechanism 102 (also called station switching mechanism 102) and a bus connecting these devices.
Outside the train operation management devices 1 and 2, a console 110,
A keyboard 111 and an external storage device 116 are connected. The external storage device 116 is adapted to be inserted with the storage medium 115, reads the program and database recorded in the storage medium 115, and reads the internal storage device 10.
Copy to 4. The station setting mechanism 102 is an internal storage device 10.
4 or may be installed outside the train operation management devices 1 and 2.

The train operation management devices 1 and 2 are connected to a network 204 of the train operation management system, and the network 204 of the train operation management system includes a central terminal 200,
The distribution device 201 is connected, and the distribution device 201 has a WAN.
, Etc., and is connected to an external terminal 203 installed in a maker or the like via a public line 202. The central terminal 200 and the distribution device 201 are the network 2 of the train operation management system.
04 is connected to another communication line.

FIG. 2 is a partition configuration diagram of the storage medium 115 of this embodiment. The area recorded in the storage medium 115 is divided into an operation area 10 required to operate the train operation management devices 1 and 2, and a plurality of station program and data storage areas 30.

The operation area 10 is divided into a station common area 15 (also called a program area 15) and a station individual data development area 20, and the station individual data development area 20 is subdivided into partitions 21 to 25.

The station common area 15 stores a control program and a database common to all station devices of the train operation management system. In the station individual data development area 20,
Station-specific data is stored. The partitions 21 to 25 of the station-individual data development area 20 are divided for each station-specific data type. For each partition,
Station individual data, equipment data, screen data, timetable data, system configuration management data and constants, network communication definition, basic data (also called common code data)
It is included.

The contents of these various data are as follows. Station-specific data is data that defines the train stop time and control method at each station. The equipment data is data that stores the configuration of the station's on-site equipment, such as the station's traffic lights, tracks, and tumblers (points), and the operating method of the on-site equipment for automatically controlling the traffic lights and tumblers. . The screen data is display data for a screen displayed on a terminal installed at each station.

[0021] The timetable data is a timetable of a train held by the train operation management device of each station. The timetable is a basic timetable created when the timetable is revised. There is an operation schedule, that is, an execution schedule that determines the order of trains to be controlled at each station in consideration of train delays and emergency suspensions, and a performance schedule that summarizes train travel records.

The system configuration management data is data describing the configuration contents of various devices installed in the station, and its constants include setting data such as initial values and threshold values. In the network communication definition data, the host name or I
Communication between devices and terminals such as P address is defined. The common code data includes a track name, a route name, and a train nickname code, and is data used for the entire train operation management system.

The storage area 30 for a plurality of station data is composed of a single partition, and the data for a plurality of stations forming the train operation management system, which cannot be shared by the entire train operation management system, are A station data 31, B. Station data 32, ...
It is recorded in directory units as data for each station, such as Z station data 33. Data 31 to 3 of each station
3 is each partition 21 of the station individual data expansion area 20
There are a disk image 42 for overwriting and copying the same size as ˜25 as one file, and a data file 41 for copying each file to the station common area 15.

Since the data is configured in this manner, it is possible to perform a high-speed and reliable file copy by transferring the file using the disk image 42.

FIG. 3 is a flowchart when the train operation management device is stopped, and FIG. 4 is a flowchart when the train operation management device is activated. If the train operation management devices 1 and 2 are switched to the train operation management device for another station during its operation, it causes a system failure of the entire train operation management system. Therefore, the station setting of the train operation management device is performed when the train operation management system cannot operate, that is, when the train operation management device is stopped or activated.

In step A-1 in FIG. 3, the station common area 1
The station setting definition file 16 in 5 is referred to. The set station definition file 16 is created by a station setting command in the station common area 15, and records information on the operating stations when the train operation management devices 1 and 2 are activated next time. Since the station setting definition file 16 is deleted in the next system activation process, it does not exist in the station common area 15 immediately after the train operation management device is activated.

When the system stop processing is started, the existence of the station setting definition file 16 is confirmed, and only when the station setting definition file exists, the train operation management device 1,
Perform station 2 resetting process.

At step A-2, the station-specific file existing in the station common area 15 is deleted. What is referred to as a station-specific file is data copied from the station-specific data development area, such as screen data of terminals under the station, execution schedules held by the train operation management devices 1 and 2 at each station, and the train operation management device 1 , 2 corresponds to the operation history by the operation.

In step A-3, the station common area expansion data 41 is copied to the station common area 15 from the directories 31 to 33 of the stations selected to be operated next time in the plural station data storage area 30. The file copied in this step includes the definition of station configuration management and configuration data, constants relating to control of station equipment, various communication definitions, and journal acquisition data. The data copied in step A-3 includes the same file as the individual station file deleted in step A-2.

In step A-4, the data stored as the disk image 42 among the data unique to the station selected to operate next time is stored in the partition 21.
Overwrite as one file in units of up to 25.

At step A-6, the station setting flag provided inside the station common area 15 is turned on. This station setting flag is a flag for taking over the station resetting process when the same train operation management apparatuses 1 and 2 are operated immediately after the train operation management apparatuses 1 and 2 are stopped. After passing through the above steps, the train operation management devices 1 and 2 are stopped.

Since the train operation management device is shut down in this way, high-speed and reliable file copying can be realized.

Next, the station resetting process at the time of system activation of the train operation management devices 1 and 2 will be described. When the system is activated, the station resetting process is performed by the two steps A-11 and A-12.

At step A-11, the state of the station setting flag 18 is detected. If the station setting flag 18 is on, it is determined that the station resetting process was executed when the system was stopped immediately before, and the station resetting process is continued. If the station setting flag 18 is off, it is determined that the station reset processing did not work when the system of the train operation management devices 1 and 2 was stopped, and the station operation is started with the same settings as when the system was stopped.

In step A-12, the communication definition file and the configuration definition file copied at the immediately preceding system stop are read, compiled into a program executable state, and written into the main memory 3. This allows
The state in which it can operate as a train operation management device is restored.

By using the above-mentioned mechanism, the train operation management devices 1 and 2 can automatically switch the train operation management device of one station as a temporary train operation device of another station without depending on the installation work from the outside. , Can be operated.

Another embodiment of the present invention will be described with reference to FIG. In the example shown in FIG. 2, as shown in step A-1 of FIG. 3, the station setting definition file 16 is created by operating the reset command of the train operation management device stored in the station common area 15. However, in this embodiment, the station setting definition file 16 is input by hardware input or signal input from the outside.
Are being created.

As shown in FIG. 4, which is an example thereof, the station selection device 120 provided outside the train operation management device 1 is provided with an electrical input mechanism such as a dial and a keypad. At the time of input of a station selection from the station selection device 120, or at the beginning of the system stop processing of the train operation management device 1 and before checking the presence or absence of the station setting definition file, the input signal is processed by the CPU unit. The station setting definition file 16 is analyzed in 101 and created in the internal storage device 104. The processes other than creating the station setting definition file 16 are the same as those in the flowchart shown in FIG.

As another embodiment using the train operation management device 1 shown in FIG. 5, the CPU 101 analyzes the output signal of the station selection device 120 at the beginning of the system stop processing to specify the next operating station. It is also possible to perform the station resetting process without using the station setting definition file.

In this embodiment, step A-1 in FIG.
Instead of, the determination of "whether a signal for station resetting is sent from the station device" is performed, and the process of "determination of the next operating station" is added between steps A-1 and A-2.

Next, another embodiment of the system control storage medium will be described with reference to FIGS. In the example shown in FIG. 2, the storage medium has a station common area 15 and a station individual data expansion area 2
The data is divided into 0 and the individual data of each station is stored in the multi-station data storage area 30.

In the example shown in FIG. 6, the programs and databases necessary for the train operation management device of each station are collectively provided without making a distinction whether the contents stored in the multi-station data storage area 30 are common to the system or individual. Then, the file is saved as one file. In this case, the entire station common area 15 is a target to be copied by overwriting, and this area cannot be used for the system stop processing. For this reason, the train operation management device 1 has the device configuration shown in FIG. 7 and is provided with a storage area 106 dedicated to station reset processing. The station reset processing of the train operation management device is executed in the storage area 106 upon receiving a call from the internal storage area 104.
In this embodiment, the capacity to be stored in the storage device inside the train operation management device increases, and it takes time to install the medium. For example, when the system is destroyed, the station is reset immediately to restore the system. Has the advantage of being easy.

Another embodiment of the present invention will be described with reference to FIG. The present embodiment is mainly used for system repair, and software repair by remote control is performed. In this example, the time zone during which the train operation management device of the station is not required to operate at the station where the system is rehabilitated, that is, the time from the time when the last train departs at the station until the arrival of the first train of the next day It is premised that the band is used.

First, the contents of the external storage medium 115 of the train operation management device are stored in the external terminal 203 owned by the manufacturer factory.
From the operation management system to the distribution terminal 201.

Next, the train operation management devices 1 and 2 are activated as a mode dedicated to receiving control software, which does not operate as a train operation management system. This is realized by new control software including the distribution-dedicated processing area 60 in the station setting mechanism 102 of FIG. 1 as shown in FIG.

In this control software, if the content recorded in the station setting definition file 16 is the distribution / reception mode, the train operation management system will not operate the next time the system is started, and the distribution exclusive use shown in FIG. The processing area 60 is used to start up the system as a control software reception mode.

In the distribution dedicated processing area 60, the communication definition of the train operation management device of each station, the station setting mechanism 102, and the station setting definition file 16 defining the station to be started after restarting.
The information unique to the train operation management device is stored. Since the system operation area 10 and the station individual data development area 20 are not used in the start-up using the distribution dedicated processing area 60, the system operation area 10 and the station individual data storage area 30 can be overwritten.

After confirming that all the stations to be distributed have started up in the mode dedicated to receiving the control software, the distribution software 201 controls the control software of the train operation management devices 1 and 2 to change the train operation management devices 1, 2. Internal storage device 1 of 2
Deliver to 04. At this time, since the software to be delivered is common to all train operation management devices, it is possible to deliver to all devices at the same time.

When the control software distribution work by remote control is completed, a system shutdown request is issued from the external terminal. At this time, the distribution-only processing area 60
The station setting mechanism 102 of the above works, and at the time of next start-up, the train operation management device of each station will not be duplicated while the software of the train operation management devices 1 and 2 of each station is modified and the communication definition of each station does not overlap. stand up.

After the end, the train operation management devices 1 and 2 perform station resetting processing. As a result, software repair work can be performed without directly installing the contents of the control storage medium 115 using the external storage device 116 connected to the train operation management devices 1 and 2.

As described above, according to this embodiment,
Version management can be simplified by sharing the software of the train operation management device. Further, the station setting mechanism can realize the setting of the station system only by restarting the apparatus by using the recording medium common to the train operation management apparatuses. Therefore, by connecting the train operation management device and the external storage device, it is possible to save the work time for performing the installation work for each train operation management device, which has the effect of simplifying the construction work of the train operation management device.
