  • FIG. 12 is a flowchart showing the operation of the train detection devices 7a to 7c according to the second embodiment.
  • the detection unit 12 communicates with another train detection device 7 via the communication unit 14 and determines whether or not the other train detection device 7 is operating normally (Ste S11).
  • the detection unit 12 sets a block section within the jurisdiction of the own device (step S12), and the train 6 is present in each block section. It is determined whether or not the operation is performed (step S13).
  • the detection unit 12 determines whether or not the own device sets the block section including the jurisdiction range of the failed train detection device 7. (Step S14). When the own device does not set the block section including the jurisdiction range of the failed train detection device 7 (step S14: No), the detection unit 12 sets the block section within the jurisdiction range of the own device (step S12). ), It is determined whether or not the train 6 is present in each block section (step S13). When the own device sets the block section including the jurisdiction range of the failed train detection device 7 (step S14: Yes), the detection unit 12 has the jurisdiction range of the own device and the jurisdiction range of the failed train detection device 7. The block section is set in (step S15), and it is determined whether or not the train 6 is present in each block section (step S16).
  • the train detection device 7a acquires the detection information of the train detection sensor 3i at the boundary between the jurisdiction range 72 and the jurisdiction range 73 from the train detection device 7c, and has jurisdiction. It is determined whether or not the train 6 is present in the block section including the range 72.
  • the train detection system 100a performs the same operation as described above even when the train detection device 7 that cannot be used in advance due to replacement or maintenance of the train detection device 7 is known. be able to.
  • the train detection device 7 that has detected a failure of another train detection device 7 is within the jurisdiction of its own device. And it was decided to set a new block section using the block section of the jurisdiction range of the other train detection device 7. As a result, the train detection device 7 can detect the position of the train 6 while avoiding the situation where the operation of the train 6 is interrupted and without increasing the installation cost and the maintenance cost.
  • the configuration shown in the above embodiments is an example, and can be combined with another known technique, can be combined with each other, and does not deviate from the gist. It is also possible to omit or change a part of the configuration.
