It can be determined that a failure such as a disconnection between the monitor m and the monitoring device 42 or a disconnection of the guide wire 2m has occurred. Further, since the monitoring device 42 supplies the detection signal S2 to the guide wire 2m, it is not necessary to lay an optical fiber cable for signal transmission in the monitoring device 42, and the equipment cost is low and
Installation work of the monitoring device 42 is facilitated.

As described above, the relay device 32 can detect the failure of the signal transmission system including the guide wire 2m, and it is not necessary to lay the power supply cable and the optical fiber cable in the monitoring device 42. It is possible to obtain an inexpensive vehicle control ground device in which the operating density of the line section is taken into consideration while maintaining the performance.

The combination of the relay device 32 and the monitoring device 42 is usually provided in the final section 1m located at the end of the vehicle 6 as viewed in the course of the vehicle. Therefore, the ground equipment can be simplified in the end section of each line section radially provided around the specific station, the end section of the branch line, etc., the installation work becomes easy, and the vehicle control is inexpensive.

In a specific example, the relay device 32 includes a verification signal generation unit 321, a detection signal determination unit 322, and a processing unit 323. The verification signal generator 321 detects the verification signal S.
1 is supplied to the guide wire 2m. The detection signal determination unit 322 is
When the detection signal S2 supplied from the monitoring device 42 is received, the determination signal S3 is output, and when the detection signal S2 is not received, the determination signal S3 is stopped. A transformer 320 is connected between the inspection signal generator 321 and the detection signal determiner 322 and the guide wire 2m to insulate the two. When the determination signal S3 is supplied, the processing unit 323 diagnoses that the transmission system including the guide line 2m is normal, and when the determination signal S3 is not supplied, the transmission system including the guide line 2m. Is diagnosed as abnormal.

The monitoring device 42 includes a power supply generation section 421, a level determination section 422, and a detection signal generation section 423.

The processing section 323 outputs an abnormality detection signal S5 when the detection signal S2 is not obtained when the verification signal generation section 321 is instructed to transmit the verification signal S1. Therefore, it is possible to notify the other control device that the section 1m is in the transmission / reception disabled state.

When the central processing unit 5 receives the abnormality detection signal S5 indicating that a failure has occurred in the section 1m, the central processing unit 5 sends a control signal for preventing the vehicle 6 from entering the section 1m to the other section 1 ( m-1). This prevents the vehicle 6 from entering the faulty section 1 m. If the vehicle 6 erroneously enters the faulty section 1m, the relay device 32 provided in the faulty section 1m cannot transmit and receive the signals F1 and F2, and the vehicle cannot be controlled. Therefore, it is important for vehicle control to prevent the vehicle 6 from entering the faulty section 1 m.

Command the transmission of signal S1. According to this configuration, when a failure such as a disconnection between the relay device 32 and the guide wire 2m, a disconnection between the guide wire 2m and the monitoring device 42, or a disconnection of the guide wire 2m occurs, the failure is detected.
