In addition, the controller 130 determines whether the train enters the railroad crossing by the respective detection signals from the train entry detection unit 110 and generates each control signal for alarming the train when the train passes. By calculating the speed of entry, the predicted arrival time to the crossing is generated and a control signal for displaying it is generated.

The train passing alarm unit 140 includes an alarm door display unit 142, an alarm lamp driver 144, an alarm sound generator 146, and a fluorescent lamp driver 148, each of which is driven and controlled by a control signal from the controller 130. do.

Here, the alarm door display unit 142 responds to the traffic conditions of each message (for example, "stop once", "pass after confirmation", "safe driving", "no speeding" depending on whether the train passes or not) Message, and when the train passes, it displays the "train passing", etc., the time to reach the crossing at the time of entering the train, the alarm light drive unit 144 is an alarm light (for example, Yellow light, red light) is turned on or blinking normally, yellow light is turned on normally, red light is repeatedly turned on and then blinks when passing the train.

In addition, the alarm light generating unit 146 generates an alarm sound in the form of a wave at the time of passing the train, the fluorescent lamp driving unit 148 to turn on the fluorescent lamp installed inside the crosswalk guide plate at night, which is the To visually alert the driver or pedestrian.

On the other hand, the traffic light control unit 150 controls the driving of the traffic light by the control signal from the control unit 130, the traffic light through the train passing alarm unit 140 as described above primarily to warn the entrance to the crossing. (Visual audible alarm), intended to provide secondary warning of train entry near vehicle entrances at crossings in case of drivers or pedestrians not seeing or hearing primary alarms (visual alarms).

Preferably, the traffic light controller 150 turns on the green light by the control signal from the controller 130, turns on the yellow light when the train enters, and then turns on the red light.

The data transmitting and receiving unit 150 is for transmitting and receiving data between the control unit 130 and the main controller 200, the main controller 200 is operated by a maintenance class member, and initializes the control unit 130 to the train passing alarm unit ( 140 and the initial state and operating conditions of the traffic light control unit 150, and the current state of the system (for example, failure of each sensor or train passing alarm unit 140) by the data transmitted from the control unit 130 To see if there is any breakdown, etc.).

With reference to Figures 1 to 3 will be described in detail with respect to the operation of the railroad crossing and the automatic alarm system of the railroad crossing according to the present invention configured as described above.

Figure 2 is a view for explaining the alarm signal detected by the train detection signal and the same using each sensor, Figure 3 is a railroad crossing of the railroad crossing in accordance with the present invention is installed around the railroad crossings with automatic alarm system It is a schematic drawing.

In Figure 2 (a) is a train detection signal detected through the first train detection sensor 112, (b) is a train detection signal detected through the second train detection sensor 114, (c) is a train The train detection signal detected through the passage detection sensor 120, (D) represents a section for alerting the train passage in accordance with the detection signal detected through each sensor (112, 114, 120).

In FIGS. 2A to 2C, the sections T1, T2, and T3 are train detection sections, which are changed depending on the length and speed of the train 50.

Next, when the main controller 200 is initially operated by the maintenance staff, command data corresponding to the main controller 200 are transmitted to the control unit 130 through the data transmitting / receiving unit 160. A control signal for switching the passage alarm unit 140 and the traffic light control unit 150 to an initial state is generated, and an operating condition is set.

Accordingly, the train passing alarm unit 140 and the traffic light control unit 150 are initialized by the control signal from the controller 130, and the operating conditions (for example, the alarm sound generating unit 146) of the train passing alarm unit 140 are initialized. Whether to generate an alarm sound or not).

That is, the message corresponding to the traffic situation among the "single stop", "pass after confirmation", "safe driving", "no speeding" is normally displayed through the alarm door display unit 142, and the alarm lamp driving unit 144 is displayed. The yellow light 152 is turned on, and the green light is turned on at the traffic light 155 through the traffic light controller 150.

On the other hand, when the train 50 enters the crossing 60, train entry is detected through the first train detection sensor 112 installed at the first predetermined position (preferably, about 2 km) before the crossing 60. (A point in FIG. 2A), a corresponding detection signal is input to the controller 130, which is continuously transmitted until the train 50 passes through the first train detection sensor 112. It is detected and input to the controller 130 ((a) of FIG. 2).

In addition, the controller 130 generates each control signal for alarming the train passing by the detection signal from the first train detection sensor 112, and the train passing alarm unit 140 by the control signal from the controller 130. The alarm door display unit 142, the alarm lamp display unit 144, the alarm sound generating unit 146, and the traffic light control unit 150 in the interior are driven to alarm the train passing.

In detail, an alarm message (for example, "train passing") is displayed through the alarm door display unit 142 by the control signal from the controller 130, and is displayed through the alarm light display unit 144. The alarm light (red light) is repeatedly turned on and blinking, and the alarm sound is generated in a wave form from the speaker 156 through the alarm sound generator 146.

At this time, the alarm sound generated from the speaker 156 through the alarm sound generating unit 146 is set at the time of initialization in the main controller 200 in a set operating condition (for example, an installation area (city area or a quiet country road)). According to the operating conditions (whether or not to generate an alarm sound), an alarm sound is selectively generated.

In addition, the traffic light 155 is driven by the control signal from the control unit 130 through the traffic light control unit 150, that is, the green light is blinking, while the yellow light is turned on and then the red light is turned on.

Therefore, while the train enters the railroad crossing 60, it is primarily visually and visually alarmed through the train passing alarm unit 140, while the vehicle 60 and the pedestrians near the railroad crossing to secondly alert the driver and pedestrian who did not see or hear it. Signal light 155 installed in the red light is turned on.

On the other hand, when the train 50 proceeds further to the crossing 60 side, the train entry is detected through the second train detection sensor 114 installed at the second predetermined position (preferably, about 1 km) before the crossing 60 ( In Figure 2 (b) B is input to the control unit 130, this detection signal is continuously detected until the train 50 passes through the second train detection sensor 114 is input to the control unit 130 (FIG. 2B).

Then, the controller 130 is the entry point (A point) of the train 50 detected through the first train detection sensor 112 and the entry point of the train 50 detected through the second train detection sensor 114. Computing the speed of entry of the train 50 according to the time difference (T4) between (B time point) to predict the arrival time to the crossing 60, generates a control signal for displaying this, and the control signal from the controller 130 The arrival time of the crossing 60 of the train 50 is displayed on one side of the alarm door display unit 142 by.

In detail, the first train detection sensor 112 and the second train detection sensor 114 in the train entry detection unit 110 are installed at the first predetermined position (about 2 km) before the crossing 60 at the time of installation and the second. Since the distances (1Km) between the sensors (112, 114) are known in advance, and are installed at predetermined positions (about 1Km), the time difference between the entry points (A and B) at which the train 50 is detected in advance. Since the entrance speed of the train 50 is calculated, the arrival time to the crossing 60 can be predicted.

Accordingly, a message (“train passing”) for the train passing is displayed through the alarm door display unit 142 in the train passing alarm unit 140, while the arrival time of the crossing 60 of the train 50 is displayed on one side thereof. do.

Next, when the train 50 passes the railroad crossing 60, the train 50 is detected through the train passing sensor 120, and a corresponding detection signal is input to the controller 130 (FIG. C)), when the control unit 130 detects that the train 50 is completely passed through the train pass detection sensor 120 (C point in FIG. 2C), a control signal for releasing the train pass alarm. Is generated, and the train passing alarm of the train passing alarm unit 140 and the traffic light controller 150 is released by the control signal from the controller 130.

That is, the message ("train passing") for the train passage displayed through the alarm door display unit 142 is the usual message ("stop once", "pass after confirmation", "safe driving", "no speeding" traffic) A message corresponding to a situation) is displayed, the alarm light (red light) that is repeatedly turned on and flashing through the alarm light driver 144 is turned on as an alarm light (yellow), and the speaker ( While the alarm sound alarmed from 156 is released, the red light of the traffic light 155 is lit by the green light by the traffic light controller 150.

On the other hand, according to the time data supplied from the main controller 200 through the data transmission and reception unit 160, the controller 130 checks the current time, and if it is determined that the current time is night, driving the fluorescent lamp installed in the crosswalk guide plate 158 It generates a control signal to make, and the fluorescent signal is driven through the fluorescent lamp driver 148 by the control signal from the control unit 130, the fluorescent lamp in the crosswalk guide plate 158 is easily lit to know that the crossing 60 at night. In addition, it can visually alert drivers and pedestrians at night.

As described above, the train passage and the automatic alarm device of the railroad crossing are provided with a symmetrical train passing alarm unit 140 and a traffic light 155 at both sides of the vehicle entrance of the railroad crossing to alarm the passage of the train at both sides of the entrance of the railroad crossing.

Therefore, according to the present invention, the first railroad visually alarms the train passing in front of the vehicle entrance of the railroad crossing, and turns on the traffic light near the railroad crossing to make the second alarm, thereby providing the railroad crossing to the driver and pedestrian of the vehicle crossing the railroad crossing. In addition to violently alarming, as well as effectively turn on the crossing at night when the information on the crosswalk effectively, there is an effect that can prevent the train accident at the crosswalk in advance.
