The other end of the winding is connected in series between the receiving transformers, and both ends are connected to the receiving input terminal of the ground receiver, and the ground receiver detects the train position based on the magnitude of the received voltage value at the receiving input terminal. Therefore, when a train enters a blocked section and the track is short-circuited by the axle, the voltage value at the receiving input terminal of the ground receiver becomes a value corresponding to the axle short-circuit position, that is, the train position. Therefore, the train position can be detected by decoding the magnitude of the received voltage value using a ground receiver. The magnitude of the voltage value is determined only by the axle short circuit position, that is, the train position.
It has nothing to do with the direction of train travel. Therefore, the train position can be detected not only for trains traveling in one direction on the track, but also for trains traveling in the opposite direction.

Because they are spaced apart, the train position can be detected at multiple points.

費が低減できる。 Furthermore, the other side of the winding of the transmitting transformer is connected to the terrestrial transmitter, and the other side of the winding of each of the receiving transformers is connected in series between the receiving transformers, and both ends of the winding are connected to the terrestrial transmitter. Since it is connected to the input terminal, the position of the train can be detected at multiple points using one transmitter and one receiver. Therefore, the configuration can be simplified and equipment costs can be reduced.

である。 Next, the operation of the train detection device according to the present invention will be explained with reference to FIG. When a train detection signal is sent from the transmitter 6 to the tracks 1 and 2 through the windings N 2 and N 1 of the transformer 9, if the train 3 does not exist in the blocked section 2T, the track by the train axle is detected in this blocked section 2T. No short circuit occurs. Therefore, the received voltage value er at the input terminal of the receiver 7 is
It is the value obtained by adding the voltages e 1 , e 2 , and e 3 induced in the windings N 2 of the receiving transformers 81 to 83 installed at ~C. That is, er=e 1 +e 2 +e 3 .

When the track 1-2 is short-circuited by the axle at the train position detection point A, the winding N 1 of the receiving transformer 81
Since both ends of are also shorted by the axle, the winding N 2
The induced voltage e 1 at . Therefore, the received voltage value er at the reception input terminal of the receiver 7 decreases by the amount of decrease in the induced voltage e1 .

とができる。 As the train 3 moves from the train position detection position A→B→C, the receiving transformer 81→82→83
Since the winding N 1 of the winding N 1 is successively short-circuited and the induced voltages e 2 and e 3 generated in the winding N 2 decrease, the received voltage value er also gradually decreases accordingly. Therefore, by decoding the magnitude of the received voltage value er with the receiver 7,
Train position can be detected. Received voltage value er
The magnitude of is determined only by the axle short circuit position, that is, the train position, and is not related to the running direction of the train 3. Therefore, the train position can be detected not only for the train 3 traveling in the direction A→B→C on the tracks 1 and 2, but also for the train traveling in the direction C→B→A.
