Abstract

PURPOSE:To provide a train controller that makes operation performable even in an unsignaled interval and high density operation achievable, respectively. CONSTITUTION:Four transmitting circuits 121 to 124 are connected to block boundaries P1 to P4, transmitting four aspect signals S31 to S34 conformed to aspect command signals S21 to S24 to a track 11. A control circuit 13 regards an aspect of a rear block interval 13T adjacent to a block interval 14T being inputted with a train detecting signal and subjected to train detection as a stop aspect and determined three aspect command signals S31 to S33 so as to make each aspect of two rear block intervals 12T and 11T turn to a host aspect in order, thereby outputting three transmitting circuits 121 to 123. On the other hand, an onboard antenna 21 receives three aspect signals S31 to S33, outputting a receiving signal R33 or the like instead. A receiving circuit 22 processes a nonsignal as the stop aspect at a time when the receiving signal R33 is this nonsignal.

The indication signal can be transmitted and received until the block boundary is reached. When the preceding train is in the closed section in front of the route adjacent to the closed section, the axle level of the preceding train causes a short-circuit on the transmission level of the signal, and the succeeding train is near the closed boundary behind the closed section in the closed section. When it is present, the display signal cannot be transmitted or received. That is, there is no signal.

The train detection signal is input to the control circuit, and the indication of the rear closed section adjacent to the closed section in which the train is detected is regarded as a stop indication, and the indication of the rear closed section becomes a higher order indication. As described above, the indication command signal is determined and output to each of the transmission circuits. Therefore, the closed section two behind the closed section where the train detection of the preceding train is detected does not become a stop indication and the train detection is It is possible to allow a succeeding train to enter up to the rear closed section adjacent to the closed section.

Since the receiving circuit receives the received signal and processes the no signal as a stop indication when the received signal is no signal, the receiving circuit adjoins the closed section in which the train detection of the preceding train is detected. When a succeeding train passes through a closed boundary at the rear of the course of the closed section, the non-signal is converted into a stop signal and the train is not suddenly braked. Also,
By the stop indication, the succeeding train can stop before the closed boundary in front of the route, so that the collision with the preceding train can be avoided. If the transmission circuit of the rear closed section adjacent to the closed section where the train of the preceding train was detected is transmitting the stop indication, the succeeding train will show the stop indication as the preceding train moves away from the block boundary in front of the route. It becomes possible to receive the display signal of. Therefore, even when the on-board device cannot receive the signal indicating the signal (when the signal cannot be received without a signal), the following train can stop before the closed section in front of the route, and it is valid that the no signal is processed as the signal indicating the stop. Be converted. This makes it possible to obtain a train control device that can be operated even in a non-signal section and can achieve high-density operation.

The on-board device has a stop indication generating circuit, and the stop indication generating circuit generates a stop indication signal and supplies the stop indication signal to the on-board antenna when the received signal is no signal. Therefore, when the succeeding train passes through the closed boundary at the rear of the route of the closed section adjacent to the closed section where the preceding train is detected, the on-board device receives the stop signal. Is denied that it is not able to receive the display signal (abnormality that cannot actually receive the display signal),
It is justified to treat the no signal as a stop indication.
When the stop notification signal is not received, it is determined that the ground device does not transmit the notification signal. As a result, a train control device capable of distinguishing an abnormality in which the on-board device cannot receive the display signal and a case where the ground device does not transmit the display signal and clarifying a non-signal section to improve reliability can be obtained. .

4 is output. The reception circuit 22 receives the reception signals R31 to R3.
When 4 is input and the received signals R31 to R34 are no signals, the no signals are processed as a stop indication ("01" indication). In the illustrated example, when the succeeding train 72 enters the closed section 12T, the reception circuit 22 is supplied with the reception signal R32 indicating "40" and the closing boundary P2 at the speed indicated by "40".
Pass through. When the succeeding train 72 enters the closed section 13T, the closed section 14T is short-circuited by the preceding train 71, and the reception signal R33 of the stop indication ("01" indication) is not supplied to the reception circuit 22, so no signal ( "02" display)
However, the receiving circuit 22 converts the no signal into a stop signal and processes it. Therefore, the succeeding train 72 is decelerated when entering the closed section 13T, and is controlled so as to stop before the closed boundary P3.

Receiving the indication signals S31 to S34 and receiving signals R31 to R3
Therefore, if the preceding train 71 is not in the closed section 14T, the subsequent train 72 is in the closed section 13T.
Until the obstruction boundary P3 ahead of the path of
You can send and receive. When the preceding train 71 is in the closed section 14T, an axle short circuit of the preceding train 71 causes a signal S3

When the vehicle is in the vicinity of the closed boundary P2 behind the 3T route, the indication signal S33 cannot be transmitted / received. That is, there is no signal.

The control circuit 13 receives the train detection signal S1 of the preceding train 71 on the track 11 and stops the display of the rear closed section 13T adjacent to the closed section 14T where the train is detected. As an indication), the indication command signals S23 to S23 so that the indications of the rearward closed sections 12T and 11T are sequentially indicated as "40" and "75" as the indication.
Since S21 is determined and output to each of the transmission circuits 123 to 121, the closed section 1 in which the train is detected
The closed section 12T two behind 4T does not show the stop,
The succeeding train 72 can be advanced to the rear closed section 13T adjacent to the closed section 14T where the train is detected.

The receiving circuit 22 receives the received signals R31 to R34.
Is input and the received signals R31 to R34 are no signals, the no signal ("02" indication) is processed as a stop indication ("01" indication). When the succeeding train 72 passes through the closing boundary P2 behind the course of the rear closing section 13T adjacent to the closed closing section 14T (when the succeeding train 72 enters the closing section 13T), no signal is displayed. Converted to and the following train 72
Never brakes suddenly. Further, by the stop indication, the succeeding train 72 can stop before the closed boundary P3 in front of the route, so that the collision with the preceding train 71 can be avoided. When the transmission circuit 123 in the closed section 13T is transmitting the stop indication, the preceding train 71 is in front of the closed boundary P
As the vehicle moves away from 3, the following train 72 can receive the stop signal indicating signal S33. Therefore, even when the on-board device cannot receive the indication signal S33 (when it cannot be received without a signal), the succeeding train 72 can stop before the closed boundary P3 in front of the route, and the no signal is processed as a stop indication. Is justified. This makes it possible to obtain a train control device that can be operated even in a non-signal section and can achieve high-density operation.

3 and the stop indication generating circuit 23 has a stop indication signal S35.
And the stop signal S33 is supplied to the onboard antenna 21 when the received signal R33 is no signal. The stop indication signal S35 may be any signal that can confirm that the onboard antenna 21 and the receiving circuit 22 can receive. From the viewpoint of safety, the embodiment is the same as the stop signal indicating signal S33 transmitted by the transmitter 123. The no-signal detection relay NSR becomes non-excited when no signal is detected, and the output contact NSR1 drops (contact conduction). The stop signal S35 is transmitted to the onboard antenna 2 by the transformer coupling.

After that, by receiving the stop notification signal S35, it is denied that the on-board device 2 cannot receive the display signal 33 (abnormality in which the actual display signal cannot be received), and the no signal is stopped. It is justified that it was processed as an indication. Further, when the stop notification signal S35 is not received, the ground device 1 outputs the notification signal 3
It is determined that 3 is not transmitted. Thereby, the case where the on-board device 2 cannot receive the display signal S33 and the case where the ground device 1 does not transmit the display signal S33 are distinguished.
It is possible to obtain the train control device that can improve the reliability by clarifying the non-signal section.

In the on-board device 2, the reception circuit 22 converts a no signal ("0 2" indication) into a stop signal ("01" indication) and processes it. Therefore, the stop indication generation circuit 23 transmits nothing. No signal (“02 indication”) may be used. In this case, the stop indication generation circuit 23 determines the transmission timing by the reception circuit 22.

In order to further improve the reliability when the ground device 1 does not transmit the indication signal S32, the on-board device stores the length of each block section 11T to 14T as data, and blocks from the running distance of the train. The boundaries P1 to P4 may be indexed and it may be confirmed that no signal is generated at the closed boundaries P1 to P4.

Since the receiving circuit 22 receives the reception signals R31 to R34 and the reception signals R31 to R34 are no signals, the reception circuit 22 processes the no signals as a stop indication. It is possible to obtain an on-board device for a train control device that can be operated even in a section and can achieve high-density operation.

Further, the on-board device 2 includes the stop indication generating circuit 2
3 and the stop indication generating circuit 23 has a stop indication signal S35.
