Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad crossing control device.

[0002]

2. Description of the Related Art FIG. 6 is a diagram showing a conventional general railroad crossing control system. In the figure, 1 is a track, 2 is a train, 3 is a railroad crossing, 4 is a control device, 5 and 6 are train detectors, and a is a train 2.
Shows the traveling direction of. In front of the railroad crossing 3, a railroad crossing control section L having an appropriate length is set. The control device 4 is composed of a computer and outputs a level crossing control signal for ringing and closing control of the level crossing alarm device based on the train detection signals obtained by the train detectors 5 and 6.

The train detectors 5 and 6 are, for example, axle short circuits,
Trains are detected by axle detection coils, light detection, and other methods. The train detector 5 is installed so as to detect that the train 2 has entered the railroad crossing control section L inside the alarm start point Ps, and the train detector 6 exits the train 2 from the alarm end point Pf behind the railroad crossing 3. It is installed to detect that

When the train 2 traveling in the direction of the arrow a enters the alarm start point Ps, and the entrance of the train 2 is detected by the train detector 5, the control unit 4 controls the level crossing for alarm ringing and door closing control. A signal is output and predetermined level crossing control is performed.

When the train 2 has finished passing through the alarm end point Pf, the train detector 6 detects the passage of the train 2 and the control device 4 outputs a leveling control signal for alarm ringing stop and door open control. .

[0006]

However, the above-described conventional railroad crossing control device issues an alarm when the train 2 is in the railroad crossing control section L, so that the succeeding train is When entering the crossing control section, the crossing control time for the preceding train is substantially extended by the succeeding train. That is, since the level crossing control condition set for the preceding train is influenced by the succeeding train, the alarm condition for each train cannot be clarified. For example, even if the following train branches off from the front of the railroad crossing and does not pass through the railroad crossing, the railroad crossing control time set for the preceding train will be extended by the entry of the trailing train into the railroad crossing control section, and The alarm continues until the vehicle exits the railroad crossing control section.

Therefore, an object of the present invention is to solve the above-mentioned conventional problems, and to provide a railroad crossing control device capable of performing railroad crossing control for each train and not generating an unnecessary railroad crossing warning.

In order to solve the above problems, the present invention is a railroad crossing control device including a railroad crossing control section, a train detector, and a control device, wherein the railroad crossing control section is internally provided. It includes a railroad crossing and is divided into a plurality of train detection sections, the train detector is provided for each of the train detection sections, and supplies a train detection signal to the control device, and the control device is the train. Performs railroad crossing control based on the detection signal, and starts a warning when a train passing through the railroad crossing enters the railroad crossing control section, and a train detection section behind the train when the train advances to the preceding train detection section Is released from the crossing control section.

[0009]

[Function] The railroad crossing control section is divided into a plurality of train detection sections including the railroad crossing inside, and the train detector is provided for each train detection section and supplies the train detection signal to the control device. The device can know the current position of the train in the railroad crossing control section.

The control device controls the railroad crossing on the basis of the train detection signal, starts an alarm when a train passing through the railroad crossing enters the railroad crossing control section, and when the train advances to the preceding train detection section. Since the rear train detection section is released from the level crossing control section, even if the succeeding train enters the level crossing control section before the preceding train leaves the level crossing control section, the level crossing control conditions set for the preceding train Not affected. Therefore, it is possible to obtain a railroad crossing control device that can control railroad crossings for each train and does not generate an unnecessary railroad crossing warning.

[0011]

1 is a diagram showing a railroad crossing control system using a railroad crossing control device according to the present invention. In the figure, the same reference numerals as those in FIG. 6 denote the same components. L0 to Ln
And Lf are train detection sections provided in the level crossing control section L, 4 is a control device, and 50 to 5n are train detectors. The railroad crossing 3 is provided in the train detection section Lf.

Each of the train detectors 50 to 5n is provided in each of the train detection sections L0 to Ln, and an axle short circuit,
A train is detected by various methods such as an axle detection coil and light detection, and a train detection signal of the train 2 is supplied to the control device 4. Therefore, the control device 4 can know the current position of the train 2 in the railroad crossing control section L.

The control device 4 performs railroad crossing control such as alarm ringing and door closing control based on the train detection signal, and when the train 2 passing through the railroad crossing 3 enters the railroad crossing control section L, the warning is started. When 2 has advanced to the preceding train detection section, for example, the train detection section L2, the rear train detection section L1 is released from the railroad crossing control section L. Specifically, train 2
Enters the train detection section L2 and the train detector 52 supplies the train detection signal of "there is a train" to the control device 4, the train 2 advances the train detection section L1 and the train detector 51 detects "no train". When the train detection signal of “” is supplied to the control device 4,
The train detection section L1 is released from the level crossing control section L. After that, the train detection sections that have passed as the train 2 travels are sequentially released from the level crossing control section L. Then, when the train 2 has advanced inside the level crossing control section L, the alarm is ended. Refer to interlocking conditions etc. for practical devices.

FIG. 2 is a time chart showing the operation of the control device shown in FIG. In the figure, the same reference numerals as those in FIG. 1 denote the same components. In the figure, the solid line part shows the railroad crossing control section of the train 2, and the dotted line part shows the open train detection section. Hereinafter, FIG. 2 will be described with reference to FIG.

When the train 2 enters the train detection section L0,
The control device 4 outputs a railroad crossing control signal for alarm ringing and door closing control in response to the train detection signal "there is a train" from the train detector 50. Train 2 is train detection section L1
After entering the train, the train detector 51 supplies a train detection signal "there is a train" to the control device 4, and then the train 2 advances the train detection section L0 and the train detector 50 outputs a train detection signal "there is no train". Is supplied to the control device 4, the train detection section L0 is released from the level crossing control section. Similar things
It is sequentially executed as the train 2 runs. Train 2 advances from train detection section Lf, and train detector 6 indicates “no train”
When the train detection signal Lf is supplied to the control device 4, the train detection section Lf is released from the railroad crossing control section L, the railroad crossing control section L is practically eliminated, and the railroad crossing control signal for alarm ringing stop and door opening control. Is output. Even if a succeeding train enters the railroad crossing control section L before the train 2 exits the railroad crossing control section L, the railroad crossing control condition set for the train 2 is not affected. For example, in the case where the following train branches off before the level 3 and does not pass through the level crossing, the following train is in the state where the preceding train is in the leveling control section L, and the succeeding train is the leveling control section L.
Even if the train enters the inside, the level crossing control time set for the preceding train is not extended by that, and if the preceding train exits the level crossing control section L, the level crossing warning control is immediately stopped. This makes it possible to control the level crossing individually for each train. In addition, the railroad crossing control can be performed while the train 2 is being tracked, and an unnecessary alarm is not generated.

FIG. 3 is a diagram showing another railroad crossing control system using the railroad crossing control device according to the present invention. In the figure, the same reference numerals as those in FIG. 1 denote the same components.

In this embodiment, the railroad crossing control section L is configured to include an alarm cancellation permission zone La, an alarm cancellation non-permission zone Ld, and an alarm termination zone Lf. The alarm cancellation permission zone La starts the alarm when the train 2 enters,
It is a zone that can be canceled depending on the interlocking conditions. The alarm cancellation disapproval zone Ld is set to prevent the alarm from being terminated due to erroneous information of the train detection signal, and cannot be canceled thereafter. The warning end zone Lf is a zone for ending the warning when the train 2 has passed. The alarm cancellation disapproval zone Ld is usually composed of a plurality of train detection sections L1 to Ln.

The control device 4 starts an alarm when the train 2 passing through the railroad crossing 3 enters the alarm cancellation permission zone La and continues the alarm unless cancellation conditions are satisfied. Train 2
When an alarm cancel prohibition zone Ld is entered, an alarm is started in any case, and an alarm is terminated when the alarm end zone Lf is advanced. In this case as well, as shown in FIG. 2, the trains are sequentially released from the level crossing control section while checking the train detection section where the train 2 has passed, so no unnecessary alarm is generated and the alarm cancellation disabling zone is not generated. Since the alarm will not be canceled after the vehicle enters the road Ld, it is possible to perform a safe and reliable crossing control.

FIG. 4 is a diagram showing a railroad crossing control system when there is a railroad crossing near a station. The figure shows a case where the train 21 and the train 22 continue to leave the station. Train 21 crosses 3
The train 22 takes a route X which passes through the train and the train 22 takes a route Y which does not pass through the railroad crossing 3. In the figure, the same reference numerals as those in FIG. 1 denote the same components. In the figure, the train detector and the control device are omitted for simplification. 21 and 22 are trains, 7 is a station, and 81 to 83 are departure signals. The alarm cancellation non-permitted zone Ld starts from the stop position of the train 2 in the station and is composed of train detection sections 1T to 3T. The warning end zone Lf is the train detection section 4T. A train detector (not shown) is provided in each of the train detection sections 1T to 4T, and as shown in FIG. 1, supplies a train detection signal to the control device.

FIG. 5 is a time chart showing the operation of the control device in the level crossing control system shown in FIG. In the figure,
The same reference numerals as those in FIG. 4 denote the same components.

The level crossing control for the train 21 will be described. Since the train 21 passes the railroad crossing 3, the departure signal 81
Train detection section 1T depending on the interlocking condition linked to ~ 83
The level crossing control section L including 4T is set. Controller 4
Outputs an alarm ringing for the train 21 and a level crossing control signal for door closing control. When the train 21 advances to the train detection section 2T, the train detection section 1T is released from the level crossing control section L. The same applies when the train 2 moves out of the train detection sections 3T and 4T.

The train 22 starts when the train 21 enters the train detection section 4T. Train 22 crosses 3
Since the vehicle does not pass through, the control device does not output the alarm ringing for the train 22 and the level crossing control signal for the door closing control. Train 2 while train 21 is in the train detection section 4T
Even if 2 enters the train detection section 2T, the level crossing control time set for the train 21 is not extended by that, and if the train 21 exits from the train detection section 4T, the level crossing warning control is performed. Stop immediately.

Even when the train 22 enters from the opposite direction, the train 21 is not affected by the train 22.
