The railroad crossing control device includes an inner section L1, a train detection circuit 1, and a control circuit 2C, and outputs a railroad crossing control signal S2 to a railroad crossing alarm device 3 or a railroad crossing breaker 4 provided in front of the station 8.

The inward section L1 includes the railroad crossing 5 and is provided in front of the route adjacent to the platform of the station 8. Normally, it is set to a range affected by the indication of the departure signal 91, and in the example shown in the figure, the sections of the track circuits 1T and 2T correspond to it. The boundary P2 of the track circuit 2T is a point where the level crossing control signal S2 is stopped.

The train detection circuit 1 includes a train 7 in the inner section L1.
The presence or absence of the train is detected and the train detection signal S11 is output. The train detection circuit 1 is generally composed of a track circuit, and a track relay (not shown) for obtaining a train detection signal of the track circuit 1T and a track relay (not shown) for obtaining a train detection signal of the track circuit 2T. Includes an AND connection circuit for the output contacts of. When the train 7 is present in either of the track circuits 1T and 2T, one of the track relays "falls" (the output contact opens), the AND circuit is not formed, and the train detection signal S11 of the train "present" is obtained. . When the train 7 is not present in any of the track circuits 1T and 2T, the track relays of both are "enhanced" (the output contact is conductive), the AND circuit is configured, and the train detection signal S11 of the train "absent" is generated. Become.

The control circuit 2C receives the train detection signal S11,
The present signal S91 of the departure signal 91 is input. When the progress signal ("blue") indicating signal S91 is input, the level crossing control signal S2 is output. When the train detection signal S11 is "present", the railroad crossing control signal S2 is continuously output based on the train detection signal S11. When the train detection signal S11 changes from the train "present" to the train "absent", the output of the level crossing control signal S2 is stopped.

FIG. 6 is a time chart showing the operation of the conventional level crossing control device. In the figure, the same reference numerals as those in FIG. 5 denote the same components.

At time t1, the control circuit 2C instructs the train 7 to depart, indicating the progress signal S9.
1 is given and the level crossing control signal S2 is output. The railroad crossing alarm device 3 sounds and the railroad crossing barrier 4 descends.

At time t2, the train 7 is in the inner section L1.
And the train detection circuit 1 outputs a train detection signal S11 indicating that the train is “present”. The control circuit 2C uses the train detection signal S1.
The output of the level crossing control signal S2 is continued based on 1 and the display signal S91.

At time t3, the train 7 has a track circuit 2T.

Stop the output of 2.

Thus, the railroad crossing control signal S2 is obtained by the signal S91 until the train 7 enters the inner section L1, and the railroad crossing control signal S2 is obtained by the train detection signal S11 after entering the inner section L1. To be Therefore, the railroad crossing alarm can be activated and the railroad crossing barrier can be lowered until the train 7 passes the railroad crossing.

[0012]

In the conventional railroad crossing control device described above, the railroad crossing control signal is output based on the progress signal of the departure traffic light until the train enters the inner section. Therefore, if the departure signal fails, the railroad crossing control signal cannot be obtained when the train departs. As a countermeasure against such a case, a manually operated lever is used.
When the substitute lever is operated in the "inversion", a signal corresponding to the progress signal of the departure signal is obtained.

However, if the substitute lever is operated to "localize" (hereinafter referred to as "early return operation") before the train enters the inner section, the railroad crossing control signal is stopped, which may lead to a railroad crossing accident. There is.

Therefore, an object of the present invention is to provide a railroad crossing control device which can prevent the railroad crossing control signal from being stopped by this early return operation and can reliably output the railroad crossing control signal until the train passes the railroad crossing. Is.

[0015]

To solve the above problems, a railroad crossing control device according to the present invention includes an inner section, a train detection circuit, and a control circuit.
It includes a railroad crossing and is provided in front of the route adjacent to the platform of the station, and the train detection circuit detects the presence or absence of a train in the inner section and outputs a train detection signal. The circuit receives the train detection signal and the substitute lever signal, outputs the railroad crossing control signal when the substitute lever signal is input, and outputs the railroad crossing control signal for a certain period of time even after the substitute lever signal is released. A control signal is output, and the railroad crossing control signal is continuously output when the train detection signal is the train "present", and the railroad crossing control signal is output when the train detection signal is the train "absent". It will stop.

As another means, the railroad crossing control device according to the present invention includes an inner section, an outer section, a train detection circuit, and a control circuit, and the inner section includes a railroad crossing. ,
The train detection circuit is provided adjacent to the platform of the station in front of the route, the outer section includes a home section, and the home section is provided behind the route adjacent to the inner section. Includes a first train detection circuit and a second train detection circuit, wherein the first train detection circuit detects the presence or absence of a train in the inner section and outputs a first train detection signal, A second train detection circuit detects the presence / absence of a train in the platform section and outputs a second train detection signal, and the control circuit includes the first train detection signal and the second train. When the detection signal and the substitute lever signal are input, and when the second lever detection signal is the train “present” when the substitute lever signal is input, the railroad crossing control is performed based on the second train detection signal. A signal is output and the first train detection signal indicates that the train is “present”. In which the continuously outputs the railroad crossing control signal, the train detection signal stops the output of the crossing control signal when it becomes a train "no".

[0017]

[Function] The inner section includes a railroad crossing and is provided in front of the route adjacent to the platform of the station. The train detection circuit detects the presence or absence of a train in the inner section and outputs a train detection signal. The control circuit continuously outputs the railroad crossing control signal when the train detection signal is the train "present", and stops the railroad crossing control signal when the train detection signal becomes the train "absent".
After the train has entered the inner section, a level crossing control signal is obtained based on the train detection signal until it leaves the inner section (passes the crossing).

Since the control circuit outputs a railroad crossing control signal when the substitute lever signal is input, when the substitute lever is operated normally, the railroad crossing is performed based on the substitute lever signal until the train enters the inner section. A control signal is obtained.

Since the control circuit outputs the level crossing control signal for a certain period of time even after the substitute lever signal has been released, even when the substitute lever is operated in a quick return operation, the level control signal is substituted based on this signal for a certain period of time. Is obtained. As a result, a railroad crossing control device can be obtained in which the railroad crossing control signal can be prevented from being stopped by this early return operation and the railroad crossing control signal can be reliably output until the train passes the railroad crossing. The certain period of time can be set by predicting the time from when the train departs until it enters the inner section.

In another configuration, the first train detection circuit detects the presence or absence of a train in the inner section and outputs a first train detection signal, and the control circuit outputs the first train detection signal to the train ", The railroad crossing control signal is continuously output, and the railroad crossing control signal is stopped when the first train detection signal is" absent ". A railroad crossing control signal is obtained on the basis of the first train detection signal until the vehicle exits the section.

The outer section includes the home section, the home section is provided adjacent to the inner section at the rear of the route, and the train detection circuit has a second train detection circuit for determining whether there is a train in the home section. The control circuit detects the second train detection signal and outputs the second train detection signal. The control circuit detects the second train when the second train detection signal is the train "present" when the substitute lever signal is input. Since the railroad crossing control signal is output based on the signal, the substitute lever signal serves as a trigger signal, and the railroad crossing control signal is obtained based on the second train detection signal until the train moves out of the platform section. When the tail of the train has advanced to the home section, the beginning of the train has entered the inner section. As a result, instead of stopping the railroad crossing control signal due to this early returning operation, the railroad crossing control signal can be reliably obtained until the train enters the inner section.

1 is a block diagram showing the construction of a first embodiment of a railroad crossing control apparatus according to the present invention. The railroad crossing control device
Including the inner section L1, the train detection circuit 1, the control circuit 2A,
The railroad crossing control signal S2 is output to the railroad crossing alarm device 3 or the railroad crossing breaker 4 provided in front of the station 8. Reference numeral 92 is a substitute lever.

If the departure signal 91 is normal, the railroad crossing control device, as described in the section of the prior art, shows the signal S9.
Based on 1, the crossing control signal S2 is output. The following description will be limited to the case where the departure traffic light 91 fails and the surrogate lever 92 is used to obtain the level crossing control signal S2.

The inward section L1 includes the railroad crossing 5 and is provided in front of the route adjacent to the platform of the station 8. Normally, it is set to a range affected by the indication of the departure signal 91, and in the example shown in the figure, the sections of the track circuits 1T and 2T correspond to it. The boundary P2 of the track circuit 2T is a point where the railroad crossing control signal S2 is stopped.

The train detection circuit 1 is used for the train 7 in the inner section L1.
The presence or absence of the train is detected and the train detection signal S11 is output. The train detection circuit 1 is a continuous detection type that detects the train 7 in the entire inner section L1, and both boundaries P1 and P of the inner section L1.
Any of the point detection type which detects the entry of the train 7 or the entry of the train 7 in 2 may be used. The illustrated example shows a continuous detection type, which is a track circuit that detects trains by short-circuiting rails between rails. A track relay (not shown) for obtaining a train detection signal of the track circuit 1T and a track relay (not shown) for obtaining a train detection signal of the track circuit 2T are configured as AND connection circuits of output contacts. That is, when the train 7 is present in any of the track circuits 1T and 2T, one of the track relays “falls” (the output contact opens), the AND circuit is not configured, and the train detection signal S11 of the train “exists”. Becomes When the train 7 is not present in any of the track circuits 1T and 2T, the track relays of both are "enhanced" (the output contact is conductive), the AND circuit is configured, and the train detection signal S11 of the train "absent" is generated. Become.

In the point detection type train detection circuit 1, for example, a not shown railroad crossing controller or an axle detector conventionally used in a railroad crossing control device is provided at both boundaries P of the inner section L1.
1 and P2, each crossing controller or axle detector is configured to detect the entry of the train 7 and the entry of the train 7. The crossing controller is described in detail in "Signal" (written by Hiroshi Yoshimura and Saburo Yoshikoshi, published by Koyusha), pages 491 to 494. The axle detector is described in detail in JP-A-3-57769.

The control circuit 2A receives the train detection signal S11,
The substitute lever signal S92 is input. Substitute lever signal S9
When 2 is input, the level crossing control signal S2 is output. Even after the substitute lever signal S92 is canceled, the level crossing control signal S2 is output for a certain period of time Td. The fixed time Td is set in anticipation of the time from when the train 7 departs until it enters the inner section L1. When the train detection signal S11 is "present", the railroad crossing control signal S2 is continuously output. When the train detection signal S11 changes from the train "present" to the train "absent", the output of the level crossing control signal S2 is stopped. The control circuit 2A can be composed of a microcomputer, a relay sequence circuit, or the like.

As described above, the inner section L1 includes the railroad crossing 5 and is provided in front of the route adjacent to the platform of the station 8. The train detection circuit 1 is provided for the train 7 of the inner section L1. The presence / absence of a train is detected and the train detection signal S11 is output.
When the train detection signal S11 becomes "absent", the railroad crossing control signal S2 is continuously output when
Since the train 2 stops, after the train 7 enters the inner section L1, the railroad crossing control signal S2 is obtained based on the train detection signal S11 until the train 7 exits the inner section L1 (passes the crossing).

Since the control circuit 2A outputs the railroad crossing control signal S2 when the substitute lever signal S92 is input, when the substitute lever 92 is normally operated, the train 7 enters the inner section L1. The level crossing control signal S2 is obtained based on the substitute lever signal S92.

The control circuit 2A outputs the level crossing control signal S2 for a certain period of time Td even after the substitute lever signal S92 is released. Therefore, the substitute lever 92 is operated to the "inverted position" and the substitute lever 92 is immediately moved to the "reverse position". Even when the quick return operation is performed to "localize", the level crossing control signal S2 is obtained for a certain time Td until the train 7 enters the inner section L1. As a result, it is possible to obtain a railroad crossing control device that can prevent the railroad crossing control signal S2 from being stopped due to the quick return operation of the substitute lever 92 and can reliably output the railroad crossing control signal S2 until the train 7 passes the railroad crossing.

And the train detection signal S11 after entering the inner section L1
Thus, the level crossing control signal S2 is obtained.

When the substitute lever signal S92 is canceled after the train 7 has entered the inward section L1, that is, after the train detection signal S11 of the train "present" is obtained, the train detection signal S
Since the railroad crossing control signal S2 is output according to 11, the output of the railroad crossing control signal S2 for a certain period of time Td may be stopped in response to the cancellation signal of the substitute lever signal S92.
