[0020]
FIG. 2 shows train on-line status and train on-line information managed by the operation management device 1. This shows a state in which a train 10 indicated by A on the up line, a train 11 indicated by B on the down line, and a train 12 indicated by C on the first downstream closed section. The on-board processing / display device 8 recognizes the radio control device 3 by using an omnidirectional antenna for each train located within the communicable range via the radio base stations 4, 5, and 6 installed in each station. Request to send your own train information. In the example shown in FIG. 2, the radio ID is N1, the column number is undetermined in the train 10, and the radio ID is in the train 11 from the on-board radio 7 from each of the three trains located in the communicable range. N2, the column number is B, and in the train 12, the radio ID is N3, and the column number is an undetermined response. The wireless control device 3 receives the train information transmitted from each train and creates a management table shown in FIG. In the case of this example, since the train information received from the train 11 is the confirmed value of B, the wireless control device 3 checks the train information with the train location information. That is, it is checked whether or not the train 11 exists in the train location information, and if it does not exist, the train is determined as an undetermined train. It is checked whether a plurality of trains 11 exist in the wireless management table, and if there are, both trains are determined as undetermined trains.
[0021]
When this collation is completed, the wireless control device 3 stores the wireless ID of the determined column number in the wireless ID column of the on-rail management table as shown in FIG. The column number information input from the on-board processing / display device 8 of the train 10 is transmitted from the on-board wireless device 7 to the wireless control device 3. In the state shown in FIG. 5 in which the train 10 has entered the platform 13, the wireless control device 3 checks whether or not the train 10 exists in the train location information on the received column number information. It is determined that there are a plurality of trains 11 in the wireless management table as a determined train, and if there are, the matching is performed with both trains as undetermined trains. When the verification is completed, the wireless control device 3 stores the wireless ID of the determined column number as shown in FIG. 5 in the wireless ID column of the on-rail management table.
[0022]
The wireless control device 3 periodically receives train location information broadcast-transmitted to the operation management network 2, and checks whether or not the train has entered the platform 13 based on the train location information. When the train enters the platform 13, it means that the train has entered the communication range of the directional antenna, and the wireless control device 3 performs the following control to identify and check the column number. Do.
[0023]
A wireless device used for communication is specified, and the antenna of the wireless device is switched to a directional antenna. In order to prevent transmission information from flowing to another line, the output of the radio is reduced. Requests that the train entering the platform 13 transmit the train information, which is the column number on the car, and the column number transmitted from the train and the column number entered for the corresponding line in the train location information. Is matched. If the collation is successful, the determined wireless ID is stored in the wireless ID column of the on-rail management table as described above. The device 3 transmits the column number information on the ground to the on-board processing / display device 8, stores the wireless ID transmitted from the train in the wireless ID column of the train management table, and the on-board processing / display device 8 The column number transmitted from the ground is stored as the confirmed column number. If the confirmed column number on the vehicle does not match the column number recognized on the ground, the wireless control device 3 transmits the column number information on the ground to the on-board processing / display device 8 and transmits the information from the train. The obtained wireless ID is stored in the wireless ID column of the train management table, and the on-board processing / display device 8 stores the column number transmitted from the ground as the confirmed column number.
[0024]
This will be described in more detail. From the state shown in FIG. 2, the train 10 moves down to the first track and enters the platform 13 as shown in FIG. The wireless control device 3 recognizes that the train has entered the down track No. 1 from the train location information, specifies the wireless device 14 for communicating with the down train No. 1 and points the wireless device 14 as shown in FIG. The antenna is switched to a sexual antenna, and the output is reduced so that the communication area is controlled so as to be able to communicate only with the train 10. The wireless control device 3 requests the train 10 to transmit the column number recognized on the vehicle. Upon receiving this request signal, the on-board processing / display device 8 of the train 10 transmits “undetermined” as recognized column number information. Upon receiving the undetermined information, the wireless control device 3 transmits to the on-board processing / display device 8 the column number information of “A” recognized on the ground. At this time, the on-board processing / display device 8 stores the radio ID N1 of the train 10 in the column of the radio ID of A in the train management table. The on-vehicle processing / display device 8 receives the column number information from the ground and stores the column number A as a fixed value.
[0025]
When C is stored as the column number information in the on-board processing / display device 8 of the train 10, the radio control device 3 determines that C in the column number information is incorrect as a result of the collation, and A The column number information “レ” is transmitted to the on-board processing / display device 8. The onboard processing / display device 8 receives the column number information from the ground, corrects the column number information C, and stores the column number A as the final value. In this way, when there is an error in the column number information or the like, the on-vehicle processing / display device 8 issues an alarm, and notifies the crew of the input error.
[0026]
With such a configuration, the crew inputs information about the line section, upper / lower distinction, column number, etc. relating to the own train from the on-board processing / display device, but this information is transmitted from the on-board radio, Since the wireless control device checks the train location information, the data on the vehicle can be checked, and even if the input data is incorrect, it can be automatically replaced with correct data. In addition, the crew can be notified of an input error by an alarm.
[0027]
The wireless control device can periodically check the train information of a plurality of trains by making a request for transmission of train information to a train that can communicate with the train. Can be narrowed down from trains not associated with the wireless ID. Therefore, it is possible to manage the train information for all the trains.
[0028]
Since the radio control device receives the train location information transmitted periodically by broadcast, it can know which train has entered the platform. For this reason, by controlling the radio base station by the radio control device, it is possible to perform radio communication only with the train entering the platform, and it is possible to reliably correct errors in the train information of the radio control device and the on-board device. .
[0029]
Next, a case where information is transmitted from a ground device to a specific train will be described with reference to FIG. When transmitting information to a specific train, information is transmitted by adding column number information of the destination train to the header information. This transmission is performed by wireless broadcast transmission from the wireless base station 4. For example, when transmitting information to the train 10, broadcast transmission is performed by adding information of column number A as header information to the header information. For this reason, the trains within the wireless communication range can receive this information, and each train reads the column number information of the destination from the header of the received broadcast data, and executes the on-board processing / display device 8. Is performed, the communication with the wireless control device 3 is performed when the column numbers match, and the transmitted train location information is displayed on the on-vehicle processing / display device 8.
[0030]
With this configuration, it is possible to perform wireless communication with the trains within the wireless transmission range, and the number of trains that respond is limited, so that errors in the train information of the wireless control device and the on-board device can be reliably determined. Can be corrected.
[0031]
【The invention's effect】
According to the present invention, it is possible to check on-vehicle data that is information on the own train input to the on-vehicle processing / display device by a crew member, and even when input data is incorrect, automatically corrects the data. Can be replaced. In addition, the crew can be notified of an input error by an alarm.
[0032]
Also, by sending a train information transmission request to a train that can communicate periodically, the train information of a plurality of trains can be collated. It is possible to narrow down from trains not associated with IDs. Therefore, it is possible to manage the train information for all the trains.
