A device that activates a warning device or barrier (hereinafter collectively referred to as a warning device) at a level crossing when a train approaches uses the rail as part of the electrical circuit to form a track circuit, and this circuit is short-circuited by the train's axle. There is an uninsulated track circuit device for level crossings that detects the presence of a train and controls a warning device. Therefore, audio frequency (abbreviated as AF) is generally used in uninsulated track circuits.
Since the following signals are used, this type of track circuit device will be referred to as an AP device hereinafter.

and drives relay BTR. In addition, the transmitter AS
Of course, the frequencies of the signals transmitted by T and BST are different from each other, and means for separating these signals, etc.
The components of the AF device are publicly known.

As described above, when the relays ATR and BTR are in the excited state, when the train T enters inside the transmission point of the transmitter AST to the track, the receiver ARV is short-circuited between the rails due to the low resistance of the axle. The received signal decreases, and the receiving relay ATR becomes de-energized and recovers. Under this recovery condition, the level crossing warning starts sounding. With such a normally closed circuit configuration, the level crossing alarm system will start sounding in the event of a failure such as a circuit failure or rail breakage, and the safety of the level crossing will be maintained.

Conventionally, private railways have generally controlled level crossings in single track sections using AF devices using the circuit shown in FIG. In other words, ATP in Figure (A) is a right direction alarm control relay that controls the alarm device when train T moves from left to right;
Similarly, P is the left direction alarm control relay, AM is the right direction memory relay, and BM is the left direction memory relay. When the train T is not present, the right direction alarm control relay ATP is the receiving relay A'l.

Now, in Figure 1, when train T enters the track circuit AT from the left, the receiving relay ATR is restored due to the axle short circuit, and the right direction alarm control relay ATP is restored in the circuit shown in Figure 1. An alarm control output is generated through its recovery contact shown in (B). In addition, the right direction memory relay AM operates via each recovery contact of the reception relay ATR and the left direction memory relay BM, and stores the rightward movement of the train T. Train T progresses and tracks circuits AT and BT
When entering the overlap section, the receiving relay BTR
is restored, but the left direction alarm control relay BTP maintains the excited state through the right direction memory relay AM and its own operation contact, and the left direction memory relay BM is not energized by the operation of the right direction memory relay. It has been disconnected and continues to be in a state of recovery.

However, the control circuit shown in FIG. 2 has the drawback that a dangerous failure occurs when the following sequence of operations is performed. The sequence operation that causes this dangerous failure will be explained with reference to the time chart in Figure 3. The figure shows that the track circuit BT is affected by a decrease in the leakage resistance of the track circuit due to rainwater, etc., a pseudo disconnection of the circuit, and This shows the sequence of operations of each relay that occurs when train T enters track circuit AT from the left while receiving relay BTR has been restored due to a fault that occurs on a daily basis, such as a crowbar short circuit between rails due to caution.

In the case of the above-mentioned failure, the receiving relay BTR is activated before the train T enters the track circuit AT and the receiving relay ATR shown in chart (a) is restored.
As the left direction warning control relay DTP has already been restored at the time (b) shown in ), the left direction warning control relay DTP is restored as shown in (d), and the level crossing warning system starts the warning operation.
The left direction memory relay BM operates as shown in chart (f). While this operation continues, train T moves to track circuit A.
When the reception relay ATR is restored at time (a) (a), the operation of the left direction memory relay BM is activated via the restoration contact ATR, as shown in the circuit of Figure 2. Continuously retained. Therefore, even if the receiving relay ATR is restored, the right direction alarm control relay ATP maintains the excited state via the operating contact BM and its own operating contact ATP, and therefore does not perform alarm control. After that, when the fault in the track circuit BT is recovered and the reception relay BTR operates at the time of (c) in Fig. 3 (b) and then the left direction warning control relay BTP operates, the train T is transferred to the track circuit. Even though I was approaching the railroad crossing from the AT side, the warning control was canceled (c)
From the point in time, the train passes through the track circuit AT and the receiving relay AT
This causes an extremely dangerous erroneous operation in which there is no alarm for a period of time t until point (a) when R operates).

In order to prevent the risk of no warning due to the above-mentioned erroneous operation, the present invention is designed to prevent a train from arriving in an overlapping section of track circuits AT and BT in a normally de-energized state, as shown in Fig. 1. By providing a train detection device OT, such as a magnetically shielded wheel detector, which becomes excited when
This prevents no alarm from occurring due to the above-mentioned erroneous operation.

Regarding the circuit shown in FIG. 9, the outline of the operation of the level crossing device during normal operation will first be explained with reference to the time chart shown in FIG. S. Fig. 3 is a time chart showing the trajectory when the train T enters the track circuit AT from the left.
When the train T enters the track circuit AT, the receiving relay ATR is restored at point (b) shown in chart (a) in Figure S due to an axle short circuit, and then the train starts moving in the right direction as shown in chart (b).

However, the left direction alarm control relay BTP continues to maintain its operation as shown in chart (f) due to the right direction memory relay AM and the excitation circuit via its own operating contacts. Even if the receiving relay BTR is restored, the right direction memory relay AM
is operating, the left direction memory relay BM is not excited and maintains the recovery state as shown in (g). Further, the left direction train arrival detection relay BR is excited under the operating conditions of the previous non-directional train arrival detection relay SR, and then continues to be excited under the respective operating conditions of the left direction alarm control relay BTP and itself. Even after this time, there is no change in the relay BTPO operation, so the operating state is maintained as shown in chart (h).

The relays in charts (a) to (jl) are the same as those in charts (a) to (j) in Figure S.When train T enters track circuit AT, the relays in charts (a) to (jl) are shown in chart (a) in Figure 6. Because the receiving relay BTR has already been restored at the time (b) shown in the chart (θ) before the receiving relay ATR is restored (a), the left direction warning control relay BTP is activated at the time (f). When the level crossing warning system is restored as shown in chart (g), the level crossing warning system starts its alarm operation.Also, the left direction memory relay BM operates as shown in chart (g), and the left direction train arrival detection relay BR operates as shown in chart (h). So the series time prime t1
It will be restored after.

After that, the train T enters the track circuit AT from the left, and the reception relay ATR is fully restored at the point (b) in chart (a), but the left direction memory relay BM has been activated before that, so the train T enters the track circuit AT from the left. The alarm control relay ATP maintains the excited state through the relay BM and its own operating contacts and does not recover, and the level crossing alarm is maintained by the left direction alarm control relay BTP.

When the train T advances and enters the track circuit BT which has returned to normal, the receiving relay BTR is restored again at the point in time (as shown in chart (e)). At this time, relay AM is operating, but since other operating conditions are not configured, left direction alarm control relay BTP continues in the recovery state, and left direction memory relay BM also continues to recover. When the train further advances and reaches the train detection device OT set in the overlap section of the track circuits AT and BT, and its internal detection relay OTR operates as shown in chart (1), an alarm will be issued for both left and right directions. Since both control relays ATP and BTP have been restored, the non-direction train arrival detection relay SR in the circuit of FIG. 9 (0) is activated as shown in chart (j).
It operates at point (e) and continues to maintain its operation until both relays ATP and BTP become operational.
