Description

  The present invention relates to a train radio system that performs radio communication between a train and a command center.

  A train radio system that transmits and receives voice and data using wireless communication has been proposed so that a train crew member and a commander at a command center can communicate with each other about information provision and status reports.

  In order to perform wireless communication in this train wireless system, first, an IC card is used to authenticate whether the operator is a crew member. And when it is authenticated that it is a crew member, a train number can be input in the train side. Here, when the train number is input, the mobile station provided in the train transmits the train number to the command center. The command center receives the train number via wireless communication and registers the train number in the train number / at-track information management table. After this registration, the registered train is managed on the command center side so that the position of the existing line can be specified. And when the commander of a command center communicates with the operator who was authenticated as a crew member, by calling the train of the registered train number, radio communication with the operator is performed.

  On the other hand, Patent Document 1 describes a wireless system in which a store side computer that manages a vehicle is provided with a biometric information reader that authenticates whether or not the user is a specific user.

Then, the touch panel 25 acquires biometric authentication data from the operator's fingerprint. Also, before and after that, the operator inputs a train number to be registered on the touch panel 25. The mobile station 22 adds the biometric authentication data acquired by the touch panel 25 to the train number input to the touch panel 25 and transmits the train number to the ground station 12 of the command center 11.

  The ground station 12 of the command center 11 receives the train number and the biometric data added to the train number from the mobile station 22 (step S1). The ground station 12 requests the biometric authentication data management server 15 to check biometric authentication data. Then, the biometric authentication data management server 15 collates the biometric authentication data acquired by the touch panel 25 with biometric authentication data held in advance. If the verifications match, the operator is a crew member, and if they do not match, the operator is the person who impersonates the crew member. Thereafter, the verification result is notified to the ground station 12. (Step S2).

  Next, the ground station 12 makes a request for registering the train number in step S1 and the collation result in step S2 in the train number / remaining line information management table 14. Here, the ground station 12 manages the on-line train information of the train 21 and specifies the on-line position of the corresponding train 21 regardless of whether the verification in the biometric authentication data management server 15 matches. The train number in step S1 and the collation result in step S2 are registered in the train number / remaining line information management table 14, and the registration result is notified to the ground station 12 (step S3).

  The ground station 12 instructs the command console 13 to display the train number in step S1, the collation result in step S2, and the registration result in step S3.

  And the ground station 12 transmits the train number of step S1, the collation result of step S2, and the registration result of step S3 to the mobile station 22 of the train 21 (step S5). The mobile station 22 provided in the train 21 displays the registration result on the monitor device 24. Here, when the mobile station 22 receives the verification result that the verification of the biometric authentication data management server 15 does not match, the mobile station 22 performs wireless data communication excluding in-line train information and wireless voice communication. Control so that it can not.

  The train radio system according to the present embodiment that performs such an operation is a malicious person whose operator has become a crew member by collating biometric data acquired on the touch panel 25 with the biometric data management server 15. Whether or not can be detected. In this embodiment, when this detection is performed, it is possible to automatically stop wireless data communication excluding on-line train information and wireless voice communication. Further, in this case, for example, the commander of the command center 11 can detect the abnormality by the display on the command console 13 or the alarm sound.

  In addition, regardless of whether or not the verification in the biometric authentication data management server 15 matches, the in-line position of the train 21 operated by the operator impersonating the crew is specified in order to manage the in-line train information of the train 21. Can do.
