[Action]

(1-1) In the device of the present invention, an A speed pattern that allows a train to operate at a speed pattern set from one station to the next station, and a speed pattern set including a temporary stop from one station to the next station By using a commutation control device that stores the B speed pattern that allows trains to operate at, the ground coil array is extended from the central part of the train stop position of one station to the center of the train stop position of the next station. By providing, if there is no train at the next station, move the train from station to station when there is no train, and if the train stops at the next station, detect it,
A station train detection device that switches the speed pattern of the commutation control device that controls the ground coil train between the station and the station that is one station after the station from the A speed pattern to the B speed pattern causes a train to go to one station. While the train is stopped, the subsequent train approaching this station is temporarily stopped in front of the station, and when the train departs and is no longer present at the station, the train that was temporarily stopped is launched and enters the station at a low speed. Also, when there is a train between stations, it detects that there is a train between stations and disconnects the power supply circuit to the section of the ground coil row starting from the center of the train stop position at the rear station. , You can operate the train safely without providing a power supply between stations.

(1-2) Since the ground coil train starts from the central portion of the train's scheduled stop position at the station, when the train departs from the station, the driving force initially reaches the first half of the train and the driving force over the entire length as the train progresses. The train will be able to start smoothly because it will be covered.

(2) When the train stops at the planned stop position of the train station, a transmitting antenna for the crossing guide line is provided at a position corresponding to the crossing guide line extending from the station where the train stops to the next station. When the train departs from the station and reaches the center of the first section of the ground coil row, the section of the ground coil row of the second section from the station is energized via the train position detector corresponding to that position. Can be done.

(3) At least the rear end of the trolley wire installed on the ground so as to come into contact with the current collector installed on the train, from the position corresponding to the center side end of the train stop planned station of the ground coil row section. The station trolley line extended to the part where the current collector of the train is located off the edge of the station, and the station extended between the station trolley line and the station trolley line of the next station The station train detector is composed of a trolley line and is installed so that it can be operated by a circuit that supplies electric power to the station trolley line. The switch that disconnects the circuit from the inverter is installed so that it can be operated by the circuit that supplies power to the inter-station trolley line.The current collector installed on the train stops the train at the train's scheduled stop position. When it is done, it will be installed at a position that touches the station trolley line Therefore, when there is a train at the station, the station train detection device is operated by using the current flowing from the power supply → station trolley line → train → earth, and there is also a train between stations. At times, a switch is used to disconnect the circuit between the ground coil section and the inverter starting from the center of the train's scheduled stop position at one station, using the current that flows from the power supply → station trolley line → train → ground. Since it is operated, these can be operated reliably, the length of the station trolley line from the position corresponding to the center side end of the train planned stop position of the station of the ground coil row section, Since at least the rear end is up to the part where the train current collector is located outside the end of the station, the station train detector continues to operate until one train completely leaves the station, and the next train Enter the station Can so as not to cause a rear-end collision.

(4) Brake operation current collector provided in the train, the brake trolley line provided in the station so as to contact the brake operation current collector, and the power supply circuit of the trolley line is opened, and at the same time the train at the station Commutation control is provided by providing a brake switch operated by a commutation control device so as to close the circuit between the inverter and the section of the ground coil row extending from the center of the planned stop position to the next station side. Apply the brakes to the train by closing the power supply circuit of the brake trolley wire until the device closes the circuit between the inverter and the section of the ground coil row extending from the center of the train's scheduled stop position to the next station. And while the brake is working,
A safety device that does not close the circuit between the inverter and the section of the ground coil row extending from the center of the train's scheduled stop position to the next station side.

(5) Also, when the brake switch opens a circuit between the section of the ground coil row extending from the central part of the train stop position of the station to the next station side and the inverter, the section forms a closed circuit. , Since the generated braking force by the back electromotive force is applied to the train, when the train enters the station, the commutation control for the ground coil in the front section acts on the rear part of the train and the braking force is applied on the front part of the train. By acting, it can reduce the speed of the train to a speed of a few km / h or less. And the number of trains
By arranging the brake trolley wire so that the train brake will work after reaching a speed of less than km / h, the train can be stopped accurately at the planned stop position.
