[0024]
　Step 100: The train 14, which is the target of the train integrity monitoring system 1, starts running.
[0025]
　Step 101: The leading vehicle side device 10 communicates with the satellite positioning system 13, positions (measures) the leading vehicle 15 during traveling, and among the positioned positions, the leading vehicle 15 passes through a certain point A. The passing time T A1 is measured, and the measured information on the passing time T A1 is associated with the information on the position of the leading vehicle 15 and recorded in the auxiliary storage device 25.
[0026]
　Step 102: The end vehicle side device 12 communicates with the satellite positioning system 13, positions (measures) the position of the end vehicle 16 during traveling, and among the positioned positions, the end vehicle 16 passes through a certain point A. The passing time T A2 is measured, and the measured information on the passing time T A2 and the position information on the position of the last vehicle 16 are transmitted to the leading vehicle side device 10. At this time, the top vehicle apparatus 10, the leading vehicle 15, the passage time T at the time of passing through the certain point A A1 and information, a trailing vehicle 16, passage time T at the time of passing through the certain point A A2 information Is transmitted to the on-board security device 11.
[0027]
　Step 103: When the on-board security device 11 measures the speed of the train 14 and receives the information of the passing time TA1 and the information of the passing time TA2 from the leading vehicle side device 10 , the measured speed and the passing time T A1 data and passing time T of A2 on the basis of the information, the train 14, the time T A1 from T A2 travel distance D traveled by A1-A2 calculates the travel distance D calculated A1-A2 information about Is transmitted to the leading vehicle side device 10. Safety device communication unit 22 of the leading vehicle apparatus 10, from the onboard safety device 11, the train 14, the time T A1 T from A2 mileage traveled until D A1-A2 receive information.
[0028]
　Step 104: calculation control section 23 of the leading vehicle apparatus 10, the position P of the leading vehicle 15 fro position P of the information and the end vehicle 16 rea based on information, train length L of the train 14 pos is calculated, calculates It is determined whether or not the difference (difference value) between the train length L pos and the mileage D A1-A2 is within the specified difference value which is the specified value. When the difference is within the specified difference value (within the specified difference value), the arithmetic control unit 23 of the leading vehicle side device 10 moves to step 105, and when the difference is outside the specified difference value (other than the specified difference value). , Step 106.
[0029]
　Step 105: Since the difference is within the specified difference value, the arithmetic control unit 23 of the leading vehicle side device 10 determines that the train integrity is appropriate, and proceeds to step 108.
[0030]
　Step 106: When the difference is outside the specified difference value, the arithmetic control unit 23 of the leading vehicle side device 10 determines whether or not “outside the specified difference value” is continuous N times, and “the specified difference value” If it is determined that "outside" is continuous N times, for example, if it is out of the specified difference value three times in a row, the process proceeds to step 107. On the other hand, when the arithmetic control unit 23 of the leading vehicle side device 10 determines that "outside the specified difference value" is not out of the specified difference value N times in a row, for example, when it is not out of the specified difference value three times in a row, the process returns to step 101. The processing of steps 101 to 106 is repeated. That is, even if the difference is determined to be out of the specified difference value once or is determined to be out of the specified difference value twice in a row, the error is acceptable. This is in consideration of the fact that the train 14 is in the tunnel and the leading vehicle side device 10 and the trailing vehicle side device 12 cannot communicate with the satellite positioning system 13.
[0031]
　Step 107: The arithmetic control unit 23 of the leading vehicle side device 10 determines that the train integrity is inappropriate (that is, the train 14 is separated) when the “outside the specified difference value” is continuous N times. Move to step 108.
[0032]
　Step 108: The arithmetic control unit 23 of the leading vehicle side device 10 notifies the on-board security device 11 and the information display terminal 40 or the central control device of the determination result in step 105 or the determination result in step 107 as the train integrity monitoring result. (Send) and end the processing in this routine. At this time, the on-board security device 11 outputs, for example, an emergency brake or notifies the central control device when the train integrity is improper. Further, since the information of the received train integrity monitoring result is displayed on the information display terminal 40, the train integrity monitoring result can be notified to the driver via the information display terminal 40.
[0033]
　According to this embodiment, the train integrity of the train can be monitored based on the function of measuring the position and time of the trailing car, which is added to the portable train taillight. That is, by using the tail train side device 12 provided with the tail light device 34, even if the train formation fluctuates, the tail train side device 12 can be simply moved to the tail vehicle 16 without adding a new device. , Can continue to monitor train integrity. Therefore, in consideration of the case where the train formation fluctuates, it is not necessary to additionally install a device for calculating the train length in all the vehicles that can be the last trains, so that the cost of the train integrity monitoring system 1 is reduced. Can contribute to. Further, when the train taillight is installed at the end, the operation method is not changed even if the train integrity monitoring system 1 according to the present embodiment is adopted.
