Train control system, on-board device, ground device, and train control method

摘要

An object of the present invention is to prevent erroneous traveling control by a pseudo signal in a no-signal allowable stop section and to clearly recognize the approach position to the no-signal allowable stop section as a safe side position. An onboard device 50 in a train control system 1 stores a transmission destination section ID included in control information 60 received from a rail when the next section or existing section is a no-signal allowable stop section. It is determined whether the control information 60 is a pseudo signal depending on whether the line ID matches the current section ID or the next section ID. In addition, the on-board device 50 recognizes that the next section is a no-signal allowable stop section based on the stored no-signal allowable stop section flag, and the no-signal time reaches the second threshold time. The approach to the no-signal allowable stop section is determined depending on whether the duration condition is satisfied. The no-signal time is an elapsed time from when the adoption of the control information 60 is finally confirmed. The position at the time corresponds to a position regarded as an entry position of the no-signal allowable stop section. [Selection] Figure 1
