Description

Door type interception system for a railway crossing

The present invention relates to a door type blocking system of a railroad crossing, and more specifically, by stepping in and out of a vehicle passing through the railroad crossing according to the speed and speed of entry of the train passing through the railroad crossing. The present invention relates to a door type blocking system for railroad crossings to prevent large accidents caused by collision with trains.

In general, railroad crossings are installed at intersections of trains passing through and points where vehicles and pedestrians pass, and the railroad crossings block the entry of vehicles and pedestrians passing through the points when the train passes. Circuit breaker is installed.

In the case of a breaker at such a railroad crossing, a railroad guide who resides separately performs a guide alarm to vehicles and pedestrians at the time when the train passes, and manually controls the breaker to perform traffic blocking.

In other words, at such railroad crossings, the railway guide knows in advance the time at which the train passes regularly, and manually operates the breaker according to the train's passing time at the command of the train driver and the central control station.

However, in the case of a conventional breaker installed at a railroad crossing, a railroad resident separately needs to know the time at which the train passes the railroad crossing and operate the breaker manually. If an error occurs or communication with the central control station and the train driver cannot be performed smoothly, it is difficult to operate the breaker in a timely manner, and thus there is a problem that a large crash may occur.

In addition, vehicles passing through these railroad crossings often pass through railroad crossings at high speed, unlike pedestrians.However, it is difficult to notify whether or not the train has passed so as to effectively reduce the passing speed of such vehicles. In addition, even if the breaker is operated by a railroad guide, if the vehicle enters inadvertently while maintaining the speed, there is no way to prevent it, so a large collision with the train may inevitably occur. Will have

Accordingly, the present invention has been made in view of the above-described conventional situation, and an object thereof is to detect a stepping and passing state of a train passing through a railroad crossing step by step and to detect a traveling speed of a train, and to enter a railroad crossing; It is to provide a door-type barrier system for railroad crossings that enables pedestrians to block traffic in multiple stages depending on the timing of the train.

In the figure, the power supply unit 48 is for supplying operating power to each driving circuit stage including the microprocessor 28.

Next, the operation of the present invention made as described above will be described in detail with reference to the flowchart of FIG. 4.

First, when the train of the upward line is entering toward a predetermined railroad crossing, the microprocessor 28 determines whether the first ascent train detection sensor SA1 detects the entry state of the train through the signal input unit 26. It is determined whether or not (step S10).

As a result of the determination, when the microprocessor 28 determines that the train detection signal is generated as a result of detecting the entry state of the train by the first up-coming train detection sensor SA1, the microprocessor 28 controls the alarm generation driver 30. By the first alarm generating unit (A1) provided at the front end of the primary circuit breaker (C1), and at the same time, the second and third alarm generating units (A2, A3) installed on the side of the road around the railroad crossing Edo alarm to warn the entry of the train is to be generated (step S11).

Here, the train speed detection unit VR installed near the railroad where the first ascending train detection sensor SA1 is installed detects the driving speed of the train and outputs a train speed detection signal to the microprocessor 28.

In this state, the microprocessor 28 determines whether the second up train detection sensor SA2 detects the entry of the train (step S12).

As a result of the determination, when it is determined that the second up train detecting sensor SA2 detects the entry of the train, the microprocessor 28 calculates the train speed detected by the train speed detecting unit VR to break the breaker. The primary circuit breaker drive motor 34 and the tertiary circuit breaker drive motor 38 are operated at a timing corresponding to the traveling speed of the train by calculating the operation timing of the circuit breaker and controlling the circuit breaker operation control unit 32 based on the operation timing. Rotationally driven to block the primary circuit breaker C1 and the tertiary circuit breaker C3 and to operate the display signal generator 46 to control the display signal generator 46. The warning lights of the warning parts 16 and 18 are repeatedly blinked in red, for example. In addition, the microprocessor 28 controls the traffic signal controller 42 to cause the traffic signal generator 44 to flash the traffic signal indicator TR at the intersection with a red light (step S13).

Meanwhile, the microprocessor 28 detects an obstacle such as a vehicle by the obstacle detecting sensor 12 installed in the blocking rod 12 while the blocking rod 10 of the primary breaker C1 moves downward. It is judged whether or not there is (step S14).

As a result of the determination, when it is determined that the obstacle detecting sensor 12 detects an obstacle even though the primary breaker C1 is in operation, the corresponding primary breaker ( After the operation of C1) is paused, the process proceeds to the process of step S14 again (step S15).

On the other hand, if it is determined that the obstacle detection sensor 12 is not detecting the obstacle according to the determination result of step S14, the blocking operation of the primary breaker (C1) is completed to completely block the traffic of vehicles and pedestrians. (Step S16).

Next, the microprocessor 28 determines whether the third up train detection sensor SA3 detects the entry of the train (step S17).

As a result of the determination, when it is determined that the third up train detecting sensor SA3 detects the entry state of the train, the microprocessor 28 controls the breaker operation according to the blocking timing calculated by the running speed of the train. By controlling the 32, the secondary circuit breaker driving motor 36 is driven to rotate at a timing corresponding to the running speed of the train so that the secondary circuit breaker C2 installed after the primary circuit breaker C1 is cut off. By doing so, it is possible to finally block the vehicle and the pedestrian inadvertently passing through the primary breaker C1 (step S18).

Next, the microprocessor 28 detects a state in which a train enters a railroad crossing in close proximity to the railroad crossing through a train entry sensor SA4, and the train corresponds to a train passing sensor SB1 on the downhill side. It is determined whether or not the state of passing the railroad crossing completely is sensed (step S19).

As a result of the determination, when the train passage sensor SB1 determines that the train completely passes the railroad crossing, the microprocessor 28 controls the alarm generation driver 30 to control the first to the first to the second. By stopping the alarm occurrence of the third alarm generators A1 to A3 and controlling the breaker operation control unit 32 to rotate the primary to tertiary breaker drive motors 34, 36 and 38. A traffic signal indicator installed at the intersection in the traffic signal generator 44 by controlling the traffic signal controller 42 while releasing the blocking operation state of the primary, secondary and tertiary breakers C1 to C3. The display is switched back to the yellow light and the green light so as to return the traffic signal (step S20).

The present invention having the above-described embodiments is, of course, not limited to the embodiment and can be carried out in various modifications within the scope without departing from the gist of course.

According to the present invention as described above, by detecting the entry state of the train entering the railroad crossing in multiple stages, by detecting the running speed of the train can be blocked step by step according to the timing corresponding to the running speed of the train. As a result, it is possible to timely perform a railroad crossing blocking operation and to prevent the risk of a collision accident, and to block a plurality of breakers in multiple stages adaptively to the speed of the train.
