By this operating means 5, how soon the car 3 arrives at the railroad crossing is operated based on the position information of this car 3 from the railroad crossing and the speed information from the speed measuring means 4, and, based on the result of this operation, this device controls so that a crossing gate 1 is not lowered until the first set car arrival time at the railway crossing, the difference between the railroad crossing arrival time obtained as the result of the operation and the set car arrival time is computed, the crossing gate 1 is lowered staggering the time to the extent of that difference, and close the railroad crossing.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a barrier control device for a railroad crossing, which is used to detect the approach of a train and control the operation of the barrier.

BACKGROUND OF THE INVENTION In recent years, railway networks have become more complex, and the number of trains running per hour has increased significantly. As a result, railroad crossing gates remain down for long periods of time, making it impossible for cars and other vehicles to pass through them, which is one of the causes of road congestion.

Hereinafter, a conventional level crossing barrier control device will be described with reference to the drawings.

FIG. 5 is a schematic configuration diagram showing a conventional level crossing barrier control device. In FIG. 5, reference numeral 51 indicates a barrier for blocking or opening the level crossing, and 52 indicates a sensing means, which senses a running train car 53 and controls the barrier 51 to block or open the railroad crossing.

In the above configuration, when the vehicle 53 approaches a railroad crossing,
When passing the sensing means 52, the sensing means 52 is turned on, and the signal is sent to the barrier 51, which is controlled to come down and block the railroad crossing. Further, the signal from the sensing means 52 controls the gate 51 to go up and open the level crossing.

Problems to be Solved by the Invention However, in the configuration of the conventional example described above, the sensing means 52
Since the railroad crossing is installed at a certain distance from the railroad crossing, if the vehicle 53 runs at an extremely slow speed, the railroad crossing will remain closed for a much longer period of time than during normal operation. Was.

The present invention solves the above-mentioned conventional problems, and makes it possible to shorten as much as possible the time that the barrier is down and block the railroad crossing, and therefore to realize a smoother flow of traffic. It is an object of the present invention to provide a barrier control device for a railroad crossing that is capable of reducing the risk of failure, and thus improving safety. It is something to do.

Means for Solving the Problems The technical solution of the present invention for achieving the above object is as follows:
means for sensing the passing of a train; speed measuring means for measuring the passing speed of the train based on information from the sensing means; and speed measuring means for measuring the passing speed of the train based on the information from the sensing means and the speed measuring means. It is equipped with calculation means for calculating the arrival time and controlling the operation of the circuit breaker.

Alternatively, instead of the sensing means and the speed measuring means in the above-mentioned technical means, the speed measuring means also serves as a means for sensing the passing of a train.

Therefore, according to the present invention, when a train is detected, the passing speed of the train is measured based on this information, and the time required for the train to reach the railroad crossing is calculated by a calculation means based on the sensing information and speed information. can be calculated and control the operation of the circuit breaker. In this way, instead of controlling the gates to be lowered based on the distance from the level crossing to the train, it is possible to control the gates to be lowered based on the time it takes for the train to reach the level crossing. It is possible to shorten the time that the power is cut off as much as possible.

In addition, by combining the sensing means with the speed measuring means,
The configuration can be simplified, and since this type of speed measurement means is already in practical use for traffic enforcement, etc., it can be used with peace of mind in terms of functionality and reduces the risk of failure. be able to.

Embodiment 811 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, a first embodiment of the present invention will be described.

FIG. 1 is a schematic configuration diagram showing a railroad crossing barrier control device according to a first embodiment of the present invention.

In FIG. 1, reference numeral 1 indicates a barrier that blocks or opens a railroad crossing, 2 indicates a sensing means for detecting a train vehicle 3, and 4 indicates a vehicle passing through the detecting means 2 based on information from the detecting means 2. A speed measuring means 5 measures the passing speed of the vehicle 3, and a calculating means 5 calculates the time required for the vehicle 3 to reach the level crossing based on the information from the sensing means 2 and the speed measuring means 4, and controls the operation of the crossing gate 1. It is. The sensing means 2 may be identical to conventional sensing means.

The operation of the above configuration will be described below.

When the vehicle 3 passes the sensing means 2, which is separated by a certain distance from the railroad crossing, the information is transmitted to the speed measuring means 4. Accordingly, the speed measuring means 4 is turned on, and the speed measuring means 4 obtains the speed at which the vehicle 3 passes the sensing means 2, and this speed information is transmitted to the calculating means 5.

On the other hand, the information from the sensing means 2 is also transmitted to the calculation means 5, and the calculation means 5 can know how far the vehicle 3 is traveling from the railroad crossing. Based on the information and the speed information from the speed measuring means 4, it is calculated how long it will take the vehicle 3 to reach the railroad crossing. Based on this calculation result, the calculation means 5 does not lower the barrier 1 until the vehicle reaches the level crossing that was originally set, and calculates the difference between the level crossing arrival time obtained as a result of the calculation and the set vehicle arrival time. is calculated, and the train is controlled to move down the railroad crossing gate 1 by the difference in time and block the railroad crossing.

In this way, in this embodiment, the barrier 1 is not controlled to be lowered depending on the distance from the railroad crossing to the vehicle 3, but is controlled to be lowered depending on the time it takes for the vehicle 3 to reach the railroad crossing. Since it is a thinking type that is designed to do this, it is possible to shorten the time that the railroad crossing is blocked by the barrier 1 as much as possible. Therefore, the flow of traffic at the level crossing can be improved.

Next, a second embodiment of the present invention will be described.

FIG. 2 is a schematic configuration diagram showing a railroad crossing barrier control device according to a second embodiment of the present invention.

In this embodiment, the same components as those in the first embodiment are given the same reference numerals, and the explanation thereof will be omitted, and the different configurations will be explained. 'The feature of this embodiment is that, as shown in FIG. 2, in addition to the structure of the first embodiment, a second A sensing means 6 is installed, and this sensing means 6 is connected to the vehicle 3.
When the vehicle passes, the control is such that the barrier L is unconditionally lowered.

Although the configuration of the first embodiment makes it possible to control the time during which the gate breaker 1 is lowered, a very dangerous situation may occur if the speed of the vehicle 3 changes drastically or if a failure occurs in the device. On the other hand, according to the present embodiment, as described above, the vehicle 3 is
Since the circuit breaker 1 is controlled to be lowered based on the detection of , even if the speed of the vehicle 3 changes drastically or a failure occurs in the device, danger can be avoided and safety can be improved.

Next, a third embodiment of the present invention will be described.

FIG. 3 is a schematic configuration diagram showing a railroad crossing barrier control device according to a third embodiment of the present invention.

In this embodiment, the same components as those in the first embodiment are given the same reference numerals, and the explanation thereof will be omitted, and the different configurations will be explained.

The features of this embodiment are as shown in Fig. 3.
Sensing means 2 and speed measuring means 4 along the traveling direction of the vehicle 3
A plurality of sets are alternately installed, and information is transmitted from the sensing means 2 and the speed measuring means 4 to the calculating means 5, so that changes in the traveling speed of the vehicle 3 can be recognized over time.

For example, assume that two sets of sensing means 2 and speed measuring means 4 are installed along the traveling direction of vehicle 3. Based on the information obtained from the sensing means 2 and speed measuring means 4 of the group farthest from the crossing, it was determined that it would take 2 minutes to reach the crossing, but 20 seconds later, the sensing means 2 and speed measuring means 4 of the group closest to the crossing Suppose that it is determined that it will take 1 minute and 30 seconds to reach the railroad crossing based on the information obtained from . There is a difference of 10 seconds in the time the vehicle 3 takes to reach the railroad crossing between the information obtained before and the information obtained later. This indicates that the vehicle 3 has accelerated and the speed has increased between the sensing means 2 and the speed measuring means 4 at these two locations. Therefore, the calculating means 5 corrects the time for the vehicle 3 to reach the railroad crossing, and
It is possible to improve safety by determining that the vehicle will reach the level crossing in a shorter time than the initially expected arrival time, sending a signal to the barrier 1, and controlling the barrier 1 to lower it.

Next, a fourth embodiment of the present invention will be described.

FIG. 4 is a schematic configuration diagram showing a railroad crossing barrier control device according to a fourth embodiment of the present invention.

In this embodiment, the same components as those in the first embodiment are given the same reference numerals, and the explanation thereof will be omitted, and the different configurations will be explained.

The feature of this embodiment is that a vehicle sensing and speed measuring means 7 is installed in which the speed measuring means 4 and the vehicle sensing means 2 in each of the above embodiments are integrated. The control is the same as in the above embodiment.

In each of the above embodiments, the speed measuring means 4 and the sensing means 2 are installed separately, but if a speed measuring means using a radar or the like is installed, sensing of the vehicle 3 can be performed at the same time as measuring the speed. , since it can also be used as a short-cut means,
There is no need to install the sensing means 2. This allows the device to be simplified and reduces the risk of failure.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, when a train is detected,
Based on this information, the passing speed of the train can be measured, and based on this sensed information and speed information, the time required for the train to reach the level crossing can be calculated using calculation means, and the operation of the crossing gates can be controlled. . In this way, instead of controlling the gates to be lowered based on the distance from the level crossing to the train (instead of controlling the gates to be lowered depending on the time it takes for the train to reach the level crossing, The time that a railroad crossing is blocked can be made as short as possible.Therefore, the flow of traffic can be smoothed.

In addition, by combining the sensing means with the speed measuring means,
The configuration can be simplified, and therefore the risk of failure can be reduced and safety can be improved.
