[Problem to be solved by the invention]

As mentioned above, it is necessary to lay a loop and provide ground control equipment (ATC) along the entire length of the track, which incurs a large cost.Also, an ATO device is required for automatic operation, and a dedicated TASC loop is installed for station stops, etc. There must be many.

In addition, in order to increase the reliability of equipment for safety reasons, it is necessary to install a redundant system of double to triple systems, and since the speed limit has several stages (5 to 6 stages), it is difficult to operate smoothly from the viewpoint of riding comfort. I couldn't do it.

An object of the present invention is to provide a vehicle signal safety method that solves these problems.

When an AC induced magnetic field for driving the ground element 11 is received from the traveling direction antenna 13 of the onboard equipment 12 via the ground element antenna 16, it is converted to DC by a rectifier, and for some reason, AC power input cannot be obtained. In this case, in order to prevent the contents of the memory 19 from being lost, the power is stored in the storage battery or capacitor 17 and becomes a DC power source for starting the ground element 11.

In this case, the AC power source may be fixed on the ground, and in this case, a coil is wound around the distribution feeder line to obtain DC power source power. The ground element 11 has a CPU 18, into which programs such as speed and ξ turns shown in FIG. 2 are input.

Make it.

At this time, the passing time, speed, and
Information such as acceleration/deceleration is received and the vehicle speed to the next 11 points on the ground is appropriately controlled. In this way, the driving time interval I
The vehicle is controlled to keep it within a certain tolerance.

In addition, when the corresponding vehicle 4 passes over the ground transceiver 11, the control device 15 and the arithmetic control 14 transmit the passing time, vehicle speed, and vehicle NOo.
