Description

  The present invention relates to a train control system, and in particular, train control that can easily rewrite track data and can reduce equipment costs by reducing the capacity of hardware on which track data is mounted. About the system.

Conventionally, on-board devices mounted on trains such as automatic train stop devices and automatic train control devices have a speed check function to prevent the train from proceeding or exceeding the speed for stop signals and speed limits. Things exist.
As a method of such a speed check function, a ground-based type that outputs and controls a speed check pattern in accordance with information from the ground device, a train position and a track recognized by the on-board device by loading the track data on the on-board device. There is an on-vehicle main type that collates data and a route condition received from a ground device and outputs a speed check pattern for a train position and an open route.

  Conventionally, in the train control device, as a system for transferring the database between the ground and the vehicle, when the train arrives at the station, it was recorded in the vehicle database by the vehicle device via the vehicle radio. When the ground device receives a data update request and the ground device receives the update request transmitted from the onboard radio, the ground processing device creates update data based on the update request, and the ground device transmits the update request to the onboard device. A technique for transmitting update data is disclosed (see, for example, Patent Document 1).

  However, in the above-mentioned conventional technology, although it is possible to perform fine control according to the track condition based on the track data in the on-board device, it is very troublesome to manage the track data loading status on each train and track data database. It has a problem that it takes. In addition, when the track data is corrected, it is necessary to rewrite the track data for each train, and there is a problem that it takes a lot of time and labor to rewrite the track data. Furthermore, since it is necessary to store track data over the entire route on which the train travels in the on-board device, a large amount of hardware for mounting a huge amount of track data is required, which increases equipment costs. It also has a problem.

  The present invention has been made in view of the above points, and can rewrite line data easily, and can reduce the equipment cost by reducing the capacity of hardware mounting the line data. The object is to provide a train control system.

A ground device 6 is installed at each boundary between these sections, and each ground device 6 has a ground radio 7 as a communication means for communicating with the on-board radio 4 of the train 2. is set up. Each ground device 6 is connected to a central device 8 that collectively manages the section line data of the route of the train 2, and the central device 8 stores the section line data for each section. A track database 9 is provided.

  And it is comprised so that the section line data of each section may be sent to the ground apparatus 6 installed in each corresponding section from the track database 9, and each ground apparatus 6 is with respect to the train 2 which drive | works the applicable section. The section line data is transmitted to the on-board wireless device 4 via the ground wireless device 7, and the section line data received by the on-board wireless device 4 is stored in the line data storage unit 5. The on-board device 3 is configured to perform traveling control of the train 2 based on the section track data stored in the track data storage unit 5.

  In the present embodiment, the communication unit is configured by the ground radio device 7 and the on-board radio unit 4, but the communication unit may be configured by, for example, a transponder.

  In FIG. 2, when the train 2 is traveling with the section A directed to the section B, the on-board device 3 determines the train 2 based on the section track data of the section A stored in the track data storage unit 5. When the train 2 reaches the boundary between the section A and the section B, the section line data of the section B is obtained from the ground device 6 installed at the boundary between the section A and the section B. The line data storage unit 5 rewrites the section line data of the section A to the section line data of the section B. And after that, traveling control is performed by the on-board device 3 based on the section track data of the section B.

  In this case, the section line data recorded in the line data storage unit 5 may be composed of section line data in which a part of the boundary portion of each section overlaps, for example. By configuring the section line data in this way, the section line data at the boundary portion of each section can always be secured. Further, as the section line data recorded in the line data storage unit 5, the line data of two sections may be transmitted from the ground device 6 to the train 2.

And when the train 2 comes to the installation position of the traffic light 10, the section device data of the section that the train 2 should travel is transmitted to the train 2 by the ground device 6 based on the route condition of the train 2, Travel control is performed based on section track data acquired based on the route condition.

  As described above, in the present embodiment, since the line data of each section obtained by dividing the route into a plurality of sections is transmitted from the ground device 6 to the train 2, the data transfer amount is small, Communication time can be shortened. Moreover, since the track data storage unit 5 of the train 2 only needs to have a capacity capable of storing section line data of one section, the capacity of hardware can be reduced, and the equipment cost can be reduced. .

  In addition, since each section line data is collectively managed in the line database 9 of the central device 8, when the line data needs to be corrected, the section line data in the line database 9 is corrected. The section track data corrected by the central device 8 is sent to each ground device 6, and the travel control of the train 2 can be performed by the section track data after the correction. Therefore, the management of the section line data stored in the train 2 and the rewriting work of the line data for each train 2 are not required, and the work accompanying rewriting of the line data can be greatly reduced.

And the section line data of the track data storage part 5 are rewritten to the newly received section line data, and the traveling control of the train 2 is performed by the on-board device 3 based on the new section line data.

  Then, when the train 2 approaches the station, the ground element 12 and the vehicle upper element 13 are electromagnetically coupled to each other so that the train 2 receives the route condition to the station, and the on-vehicle device 3 uses the train 2 based on the section line data. And the route control of the train 2 is performed based on the route condition.

  As described above, in this embodiment as well, as in the first embodiment, the line data of each section obtained by dividing the route into a plurality of sections is transmitted from the ground device 6 to the train 2. The transfer amount of the train 2 can be reduced, the communication time can be shortened, the hardware capacity of the train 2 can be reduced, and the equipment cost can be reduced.

  In addition, since each section line data is collectively managed in the line database 9 of the central device 8, the section line data of the line data in the line database 9 is corrected when the line data needs to be corrected. It is only necessary to manage the section line data stored in the train 2 and to rewrite the line data for each train 2, and the work associated with the rewriting of the line data can be greatly reduced. Furthermore, since the section line data of the route on which the train 2 travels is acquired when the train 2 passes the installation position of the ground device 6, the train 2 is stopped when the section line data cannot be acquired. Safety control such as making it possible becomes possible.

  Furthermore, in this embodiment, since the ground element 12 that transmits the route condition to the train 2 is installed in the vicinity of the station, the traveling control of the train 2 is performed based on the section line data, and received from the ground element 12.
