Description

TECHNICAL FIELD The present invention relates to a train information system mounted on a train connecting a plurality of cars and for supporting a driver on board the train.

A train information system of this type is known, for example, from Patent Document 1 (see prior art section). In this system, each vehicle is provided with a terminal device capable of communicating with each other, and each terminal device controls various devices provided in each vehicle according to vehicle operation data stored in advance. Here, "vehicle operation data" generally refers to the vehicle type, vehicle number and formation of each vehicle that constitutes the train, type of train such as express or limited express, starting station, destination (terminal station), stopping station, each station of the train It refers to the train schedule (so-called train schedule) that defines the train plan for each train that operates all day within a predetermined period, such as the operation section, speed type, arrival and departure times at each station, etc. Such train schedules are converted into data. are stored in a file format in storages (storage units) attached to terminal devices of all trains (for example, leading cars) in operation. An identification number (so-called "train number") is normally assigned arbitrarily to each train to be operated within the classification of the train schedule, and is similarly stored as vehicle operation data. In addition, "various types of equipment" refers to equipment that is installed in each car as necessary for train operation. It refers to the main circuit system of a train that operates according to the powering command and braking command by the operation of the controller.

Both leading cars on which the driver rides are provided with a driver display and a storage storing vehicle operation data. personnel). When the driver operates a predetermined train, he/she operates the display for the driver at the starting station based on the driver's itinerary carried by the driver. Specifically, basic information such as the train number of the train to be operated is manually entered. Then, whether or not the input train number exists is searched from the rolling stock operation data, and the rolling stock operation data corresponding to the searched train number is displayed on the display for the driver (for example, the train Various information such as number, destination and starting station are displayed).

If the displayed information matches the description in the driver's itinerary, the driver approves this by operating the driver's display. As a result, the train information system automatically distributes the initial setting command to various devices, and the train becomes ready for commercial operation. "Initial setting command" refers to the operation command for various devices such as destination indicators, air conditioners, lighting fixtures and on-board announcement devices installed in each car according to the matching train car operation data. In response to this, various devices operate (for example, the name of the terminal station is displayed on the destination display, or information such as the stop station and stop time is output by voice from the on-board announcement device). Then, the driver operates the train according to the information described in the driver's route table and the display of the signal system, etc. During operation, the terminal device of the leading car communicates with various devices and the information is collected, and the collected information is displayed on the display for the driver, and in addition, for example, guidance display in the train and in-train announcement are automatically performed according to the point information of the train. However, in such a train information system, since the driver manually inputs the train number by operating the display for the driver, there is a possibility that an input error may occur.

JP 2016-226220 A

In view of the above points, it is an object of the present invention to provide a train information system that can further reduce the burden on the driver while suppressing the occurrence of input errors as much as possible.

In order to solve the above problems, a train information system according to the present invention is installed in a train in which a plurality of cars are connected to support a driver who is on board the train. Each terminal device is provided, and each terminal device controls various devices provided in each car according to pre-stored car operation data, and a driver's display and a two-dimensional symbol reader are installed in the leading car of the train. In preparation, a two-dimensional symbol that encodes operation information related to train operation is displayed on the driver's itinerary that the driver carries. An initial setting command is generated from the related information and vehicle operation data and distributed to each terminal device, and each terminal device controls various devices according to the initial setting command, and displays the operating state of each device for the driver It is characterized in that it is configured to be displayed on a display.

Here, "operation information" means information determined for each train, namely, train number, train type, stopping station, name of main passing station, arrival and departure time at each stopping station, time at main passing station It refers to the passing time, etc., and this operation information is also displayed on the "driver's route table" carried by the driver. Then, when the driver operates a predetermined train, when the two-dimensional symbol is read by the two-dimensional symbol reader at the starting station, information on train operation (that is, operation information) is input to the terminal device of the leading car. Then, this information is collated with the vehicle operation data stored in the storage, and those that match are delivered to each terminal device as an initial setting command and displayed on the display for the driver. Thereafter, as in the conventional example, the driver operates the train according to the information described in the driver's route table and the display of the signal system. In this way, in the present invention, by adopting a configuration in which operation information, which has conventionally been manually input, is displayed as a two-dimensional symbol on the driver's route table that the driver always carries, and this two-dimensional symbol is read, It is possible to further reduce the burden on the driver while suppressing the occurrence of input errors as much as possible.

By the way, conventionally, for one train, the daily operation pattern from leaving the shed to entering the shed through commercial operation, turnaround at the terminal station, forwarding operation, etc. is a chain of "train numbers" (that is, train formation A rolling stock operation plan is created to indicate what kind of train number the train set is to be assigned to and operated on a unit basis), and this is also stored as rolling stock operation data. Then, for example, when turning back at a terminal station, confirmation is also made as to whether the rolling stock operation plan is followed. On the other hand, when the timetable is revised, the rolling stock operation data including the rolling stock operation plan and the driver's itinerary are renewed accordingly, and the renewed rolling stock operation data is stored again in the storage of all trains. verification work will be carried out at the same time. In other words, if there is a timetable revision, the rolling stock operation plan as a chain of "train numbers" is created again, and the verification work is carried out, so there is a problem that the work load is heavy.

In the present invention, the operation information includes the train number of when this train will be used next. According to this, since "operation information" in the train information system is generated for each train number, information as a chain of "train numbers" can be made unnecessary (furthermore, searching for vehicle operation data is unnecessary). can be done). As a result, the work of writing rolling stock operation data to the storage of the train information system and its verification work, which were conventionally performed when timetables were revised, can be made unnecessary, and the work load can be significantly reduced.

The figure explaining the train which mounts the train information system of this embodiment. The figure explaining the driver course table which a driver carries. FIG. 4 is a flow diagram for explaining the procedure for starting commercial operation at the starting station;

Hereinafter, with reference to the drawings, an embodiment of the train information system of the present invention for supporting the driver on board the train, in which the train is a four-car train and the two-dimensional symbol is a QR code (registered trademark), will be described. do.

Referring to FIG. 1, the train information system TS of the present embodiment includes terminal devices 2 ₁ to 2 4 installed in respective cars _{1 1} to 1 ₄ , and each terminal device 2 ₁ to 2 ₄ connects between the cars. They are communicatively connected to each other via a transmission line 3 . As the terminal devices 2 ₁ to 2 ₄ and the inter-vehicle transmission line 3, well-known devices are used, and detailed description thereof will be omitted here. Each vehicle 1 ₁ to 1 ₄ is equipped with various devices 11a to 11n that operate in response to commands from the respective terminal devices 2 ₁ to 2 ₄ . "Various types of equipment _{" refer to those necessary for the operation of the train, which are provided in each car 1 1 to 1 4. For example ,} destination displays, air conditioners, etc. , lighting equipment, and the main circuit system of the train that operates according to the power running command and brake command by the operation of the master controller by the driver.

Among the cars 1 ₁ to 1 ₄ , when the train is running (including the turnaround operation), the car that the driver gets on and heads (hereinafter referred to as “lead car 1 ₁ ” and “lead car 1 ₄ ”) is provided with storages 4a and 4b as storage devices and driver displays 5a and 5b. Each storage 4a, 4b stores vehicle operation data. The "rolling stock operation data" referred to here means the type of each rolling stock 1 ₁ to 1 ₄ that make up the train, the rolling stock number and formation, the train type such as express or limited express, the starting station, destination, stopping station, and each station of the train. It refers to the train plan (so-called train schedule) that defines the train plan for each train that runs all day within a predetermined period, such as the operation section, speed type, arrival and departure times at each station, etc. The driver displays 5a and 5b are for interaction between the train information system TS and drivers (including crew members and maintenance personnel), and include touch-type displays 51, for example. The display 51 displays various information such as the train number, destination and starting station, and also allows confirmation of the operating states of various devices 11a to 11n. The leading vehicle 1 ₁ and leading vehicle 1 ₄ are also provided with two-dimensional symbol readers 6a and 6b for reading QR codes (registered trademark). (not shown) to both terminal devices 2 ₁ and 2 ₄ of both leading vehicles 1 ₁ and 1 ₄ . Since well-known two-dimensional symbol readers 6a and 6b are used, detailed description thereof is omitted here.

On the other hand, a driver who takes a train carries a driver's route table 7 printed as a form. In the driver's route table 7, as shown in FIG. 2, operation information 71 regarding train operation is described. The operation information 71 is information determined for each train, that is, train number, train type, stopping station, names of main passing stations, arrival/departure times at each stopping station, passage times at main passing stations, and the like. . In this embodiment, the driver's route table 7 also includes a QR code 72 that encodes operation information as additional information. In this case, the operation information may include the "train number" of when this train will be used next. The detailed specifications of the QR code 72 are standardized by JIS X 510, and the details of the QR code generation process conform to this standard. Then, when the driver is on board, the train is operated according to the following procedure.

Referring also to FIG. 3, the driver who got on the leading car ₁₁ at the starting station first operates the touch-type display 51 to clear the set information of "train number" (S1). read the QR code 72 of the driver route table 7 carried by the two-dimensional symbol reader 6a. Then, information on train operation (that is, operation information) is input to the terminal device _2-1 of the leading car _1-1 , and the terminal device _2-1 compares the operation information with the vehicle operation data stored in the storage 4a, If there is a match, the operation information is displayed on the display 51 (S2). The operation information displayed in this case includes the starting station name, timetable type, train number, train number at the time of turnaround operation, and the station name if there is a temporary stop station. Next, the driver confirms whether what is displayed on the display 51 and what is described in the driver's route table 7 match, and if they match, the display 51 is operated to set Confirmation processing is performed (S3). As a result, the terminal device 2 ₁ approves this and distributes it as an initial setting command to each terminal device 2 ₂ to 2 ₄ via the inter-vehicle transmission line 3, and the train is ready to start commercial operation. .

The "initial setting command" refers to various devices 11a such as destination displays, air conditioners, lighting fixtures, and in-car announcement devices installed in each car ₁₂ to ₁₄ according to the matching train car operation data. 11n, and each terminal device 2 ₂ - 2 ₄ operates various devices 11a - 11n according to the initial setting command (for example, display the name of the terminal station on the destination display, or Information such as stop stations and stop times is output by voice from a broadcasting device). Then, the driver operates the train according to the information described in the driver's route table 7 and the display of the signal system, etc. During operation, for example, the terminal device 2 ₁ of the leading car unit ₁ Communicate with each of the terminal devices 2 ₂ to 2 ₄ via the inter-both transmission line 3, collect information when each of the terminal devices 2 ₂ to 2 ₄ controls the operation of various devices 11a to 11n, and collect this information. In addition to displaying the information on the driver's display 7, for example, guidance display in the vehicle and in-vehicle announcement are automatically performed. Further, when the operation information displayed by the QR code 72 includes the "train number" of the next train to be used, the various devices 11a to 11a installed in each car 1 ₁ to 1 ₄ respectively 11n, in particular, the destination display device and in-vehicle guidance display device of the next leading car ₁₄ can be caused to display the destination of the next operation, the type of train, etc., for example, in the section before arriving at the end point.

According to the above embodiment, the operation information, which has conventionally been manually input to the display 51, is displayed as a QR code 72 as a two-dimensional symbol on the driver's route table 7 which is always carried by the driver. can be read, it is possible to further reduce the burden on the driver while suppressing the occurrence of input errors as much as possible. According to current electronic technology, the operation information 71 described in the driver's route table 7 is recorded on an electronic medium such as a smartphone or tablet, and transferred to the train information system TS using, for example, wireless communication means. However, as in the present embodiment, relatively inexpensive two-dimensional symbol readers 6a and 6b can be used without significantly changing the format of the driver route table 7 currently used in paper media. In addition, just by changing the software accompanying this, it is possible to improve the efficiency of the row number setting work, and to greatly reduce the maintenance work at the time of timetable revision, which is useful.

In addition, when the operation information is QR coded, if it is coded in the byte mode, the binary data can be coded as it is, which is advantageous because a large amount of information can be expressed in a code with a small area. . Furthermore, since the operation information includes the train number of the next train to be used, the "operation information" in the train information system is generated for each train number. It is possible to eliminate the need for chain information (which in turn eliminates the need for searching for vehicle operation data). As a result, it is possible to eliminate the need for the work of writing vehicle operation data to the storage of the train information system and the verification work, which were conventionally performed when timetables were revised, thereby significantly reducing the work load.

Although the embodiments of the present invention have been described above, various modifications are possible without departing from the scope of the technical idea of the present invention. In the above embodiment, the two-dimensional symbol is a QR code (registered trademark), but it is not limited to this. Symbols are standardized by ISO/IEC and used, and may be used according to the application.
