Description

  The present invention relates to a technology relating to railroad crossing security in which the safety of a railway is improved by monitoring a person passing through a railroad crossing.

When a train approaches a railroad crossing, the railroad safety device detects the train approach and starts sounding the railroad crossing alarm. After a predetermined time, the railroad crossing road is lowered to block the railroad crossing. wait. After that, when it is detected that the train has passed the railroad crossing, the barrier fence is lifted to cancel the crossing of the railroad crossing.
The time from the start of the sounding of this level crossing alarm to the descent of the barrier is determined on the assumption that healthy pedestrians can travel at a normal speed, but elderly people, people with disabilities and people who are pushing bicycles. Are relatively slow walking speed, and further safety measures are required for people with slow walking speed.

  For example, in the railroad crossing safety device disclosed in Patent Document 1, a pedestrian or the like will sound a level crossing alarm by notifying a pedestrian or the like that the level crossing alarm will sound from a predetermined time before the level crossing alarm is sounded. Thus, it is possible to estimate the time when the barrier fence of the railroad crossing barrier starts to descend, and the safety of pedestrians such as elderly people who require a long time for walking compared to healthy pedestrians can be achieved.

  Moreover, in the pedestrian accident prevention system shown by patent document 2, the pedestrian presence signal which alert | reports the presence of a pedestrian is wirelessly transmitted to the level crossing side by the mobile telephone transmitter / receiver which a pedestrian can carry, Railroad crossing-related information such as that the current location is a railroad crossing is wirelessly transmitted to the pedestrian side to notify the mobile phone transceiver. This makes it possible to notify pedestrians confined in the level crossing of information relating to the level crossing escape.

  Moreover, in the collision prevention system shown by patent document 3, the speed and position of a vehicle are monitored and controlled about the collision which vehicles relate, such as collision between vehicles, a vehicle and a pedestrian, a vehicle and a train, a vehicle, and a fixed object, Prevent by recording and reporting. And by these measures, the vehicle speed is reduced or the movement of the vehicle is regulated to control speed violations, movement violations, and specific dangerous acts.

And outputs a warning signal to the crossing passage person.

  Further, the present invention is a railroad crossing equipped with an alarm device that notifies the approach of a train with a warning sound and a warning light, and a barrier fence elevator that lowers the barrier fence after the alarm is activated and blocks traffic. A monitoring program for providing safety information to a person who passes through the railroad crossing, wherein the train travel data acquisition stage acquires train travel data related to the position and speed of the train approaching the railroad crossing, and the train travel data The train travel data acquired in the acquisition stage, when the train approach to the railroad crossing is detected, the passer movement data acquisition stage for detecting the movement status of the crossing person passing through the crossing, and the train obtained in the above stage A passability determination step for determining whether or not the crossing passer can pass through the crossing based on the travel data and the passing person movement data, and the passability determination step includes a determination result of the crossing passability determination result. Hazuki, and outputs a warning signal to the crossing passage person.

According to the present invention, when the train approach to the railroad crossing is detected based on the train travel data related to the position and speed of the train acquired by the train travel data acquisition means (train travel data acquisition stage), the passing person movement data is acquired. The means detects the state of movement of a person passing through the level crossing.
Thereafter, in the passability determination means, it is determined whether or not the crossing passer can pass through the train based on the train travel data and the passing person movement data obtained by the means, and a warning signal is sent to the crossing passer by the determination result. Can be output.
For example, according to the warning signal output from the passage determination unit, information such as “return” or “pass” is written to the person passing the level crossing before the barrier is lowered by the barrier 桿 elevator after the alarm is activated. It can be displayed, or displayed by text or voice. Furthermore, when it is determined that a crossing person has difficulty crossing, a train control signal can be output to the train together with a warning for the crossing person.

In addition to this, based on the warning signal output from the passage permission determination means, when the level crossing person determines that crossing is difficult before the alarm is activated, a train control signal is output to the approaching train You can also. In addition, in the pass / fail judgment means, there is a possibility of a collision with the train based on the train travel data and the passer-by movement data when there is still a crossing person in the crossing after the barrier fence is lowered by the barrier fence elevator.

The monitoring system 10 includes a train travel data acquisition unit 11, a passing person movement data acquisition unit 12, and a passage permission / inhibition determination unit 13.

The train travel data acquisition means 11 is based on the train operation data managed by the operation management center, the passage detection signal of the train passage sensor arranged along the track, or the signal switching signal of the train A approaching the railroad crossing 1. The position and speed are detected, and the detection result is output as train travel data (a).
The passing person movement data acquisition means 12 is a crossing passer B passing through the level crossing 1 when a train approach to the level crossing 1 is detected from the train driving data (a) acquired by the train driving data acquisition means 11. It is for detecting the passing person movement data (b) which shows the movement condition of.

Further, when the passing person movement data acquisition means 12 is a radar using light / radio waves, specifically, a laser radar (for example, manufactured by Hitachi Information & Communication Engineering Co., Ltd.), a radio wave radar such as a millimeter wave (for example, Panasonic). Detection means such as Doppler radar (developed by Professor Tomoaki Ohtsuki, Keio University). By using these detection means, it is possible to detect an object regardless of day and night compared to video images. Even after the blocking fence 4 is cut off, pedestrians can cross the blocking fence elevator 5 and cross it. In the case of Doppler radar, it can be applied to detection of falls, etc. rather than instantaneous speed change.
Further, the passing person movement data acquisition means 12 is not limited to the detection means shown in FIG. 1, but uses a monitoring video that captures the entire level crossing 3 as shown in FIG. The movement status of the passer-by B may be detected.
The movement status of the crossing passer B detected by the passer movement data acquisition means 12 includes an action pattern in addition to the moving speed of the crossing passer B.

  Passability determination means 13 is based on train travel data (a) obtained by train travel data acquisition means 11 and passer movement data (b) obtained by passer movement data acquisition means 12. It is determined whether or not a railroad crossing is permitted, and a train control signal (s1) and a warning signal (s2) are output to a crossing person B based on the determination result.

In addition, indicators 20 and 21 are provided at both doorways of the railroad crossing 3 of the railroad crossing 1. As these indicators 20 and 21, a character indicator that indicates the warning signal (s2) output from the passage permission / inhibition determining means 13 with characters for the crossing passer B, a voice indicator that indicates with voice, and the like are employed. Note that the voice display is preferably provided selectively with respect to the character display.
In addition, the contents displayed on these indicators 20 and 21 include “please hurry back” or “please hurry up” as shown in FIGS. 4 (A) and 4 (B), There is a display such as “Approaching”.

Next, with reference to FIGS. 3A and 3B, the specific control contents (monitoring program executed by the computer) of the passage permission determination means 13 shown in FIGS. 1 and 2 for each step (SP). Explained. First, the first half of the step will be described with reference to FIG.
[Step 1]
Train travel data (a) obtained by the train travel data acquisition means 11 and passer movement data (b) obtained by the passer movement data acquisition means 12 are captured.

[Step 2]
Based on the train travel data (a) obtained by the train travel data acquisition means 11, it is determined whether or not the train A is approaching the railroad crossing 1. If YES, the process proceeds to the next step 3. Return to step 1.

[Step 3]
Based on the passer movement data (b) obtained by the passer movement data acquisition means 12, it is determined whether or not there is a crossing passer B in the crossing 3 of the crossing 1. If YES, the process proceeds to the next step 4. If NO, return to the original step 1.

[Step 4]
The possibility of collision between train A and level crossing person B is determined. Details of this step are shown in the following steps 10 to 25 (see FIG. 4B).

[Step 10]
It is determined whether or not the alarm device 2 that notifies the approach of the train A with a warning sound and a warning light has started to operate. If NO, the process proceeds to the next step 11, and if YES, the process proceeds to the next step 13.

[Step 11]
Before the alarm 2 operates, the railroad crossing of the railroad crossing 1 based on the train travel data (a) obtained by the train travel data acquisition means 11 and the passer movement data (b) obtained by the passer movement data acquisition means 12 3, it is determined whether or not there is a possibility of collision with the train crossing person B and the train A. If YES, the process proceeds to the next step 12, and if NO, the process returns to the original step 10.

[Step 12]
After passing the train control signal (s1) so as to decelerate the train A on the assumption that the crossing passer B in the railroad crossing 3 may collide with the train A, the process returns to the original step 10.
Note that these steps 11 to 12 are those that pass through the crossing B (for example, walking within the crossing) that is clearly taking an abnormal action before the alarm device 2 that informs the approach of the train A with a warning sound and a warning light is activated. This is a process for promptly detecting a person falling down, senior car / automobile derailment, etc.) and preventing a collision accident with train A in advance.

[Step 13]
After the operation of the alarm 2, the railroad crossing of the railroad crossing 1 based on the train travel data (a) obtained by the train travel data acquisition means 11 and the passer movement data (b) obtained by the passer movement data acquisition means 12 3, it is determined whether or not there is a possibility of collision with the train crossing person B and the train A. If YES, the process proceeds to the next step 12, and if NO, the process proceeds to the next step 14.

[Step 14]
On the basis of the passing person movement data (b) obtained by the passing person movement data acquisition means 12, the first zone on the front side in the traveling direction (in this example, the direction of the arrow (b)) of the crossing person B in the railroad crossing 3 It is determined whether the vehicle is in Z1 or the second zone Z2 on the front side in the traveling direction. If the crossing passer B is in the first zone Z1, the process proceeds to the next step 15. If the crossing person B is in the second zone Z2, the next step is performed. Proceed to 18.
These zones are set with the first zone Z1 on the near side in the traveling direction (in this example, the direction of the arrow (A)) with the track R in the railroad crossing 3 as the boundary, It is divided into a second zone Z2 on the side. Also, in this example, an example in which the crossing passer B travels in the direction of the arrow (A) has been described, but when traveling in the direction of the arrow (B), the settings of the zones Z1 and Z2 are reversed.

[Step 15]
From the passing person movement data (b) obtained by the passing person movement data acquisition means 12, the moving speed or behavior pattern of the crossing person B in the first zone Z1 is calculated, and the calculation result and the level crossing 3 of the crossing 1 of the crossing 1 are calculated. Based on the length, it is determined whether or not the crossing person B can turn back on the level crossing road 3 (in this example, whether it can be reversed in the direction of travel (in the direction of the arrow (A)). If NO, go to the next step 17.

[Step 16]
As shown in FIG. 4A, the display means 20 displays “Please hurry back”, and prompts the crossing person B to leave the first zone Z1 in the crossing road 3 promptly.

[Step 17]
After passing the train control signal (s1) to decelerate the train A on the assumption that the crossing passer B in the railroad crossing 3 may collide with the train A, the process proceeds to the next step 20.

[Step 18]
From the passing person movement data (b) obtained by the passing person movement data acquisition means 12, the moving speed or action pattern of the crossing person B in the second zone Z2 is calculated, and the calculation result and the level crossing road 3 of the crossing 1 are calculated. From the length, it is determined whether or not the crossing passer B can cross the railroad crossing road 3 (in this example, whether or not he can travel in the direction of travel (in the direction of the arrow (A)). If NO, go to the next step 17.

[Step 19]
As shown in FIG. 4 (B), “Please hurry up” is displayed on the display means 20 to prompt the crossing person B to leave the second zone Z2 in the level crossing 3 quickly.

[Step 20]
For the passage of the train A, the barrier rod elevator 5 is operated to lower the barrier rod 4.

[Step 21]
Based on the passer movement data (b) obtained by the passer movement data acquisition means 12, it is again determined whether or not there is a crossing passer B in the crossing road 3 of the crossing 1 and if this determination is NO, this flow is executed. finish.

[Step 22]
After the operation of the barge elevator 5, the railroad crossing of the railroad crossing 1 based on the train travel data (a) obtained by the train travel data acquisition means 11 and the passer movement data (b) obtained by the passer movement data acquisition means 12 A determination is made as to whether or not there is a possibility of collision between the railroad crossing person B in the road 3 and the train A. If YES, the process proceeds to the next step 23, and if NO, the process proceeds to the next step 24.

[Step 23]
After passing the train control signal (s1) so as to cause the train A to make an emergency stop on the assumption that the crossing passer B in the railroad crossing 3 may collide with the train A, this flow is finished.

[Step 24]
The display means 20 displays “please exit from the level crossing” to prompt the level crossing person B to leave the level crossing 1 quickly, and after photographing the level crossing B by the camera, this flow is finished. .

As described above in detail, according to the monitoring system and monitoring program for a crossing passer B according to the present embodiment, based on the train travel data (a) relating to the position and speed of the train A acquired by the train travel data acquisition means 11. When the train approaching to the crossing 1 is detected, the passing person movement data acquisition means 12 can detect the movement status of the crossing passer B passing through the crossing 1.
Thereafter, the passability determination means 13 determines whether or not the crossing passer B can pass the crossing based on the train travel data (a) and the passer movement data (b), and the crossing passer B is determined based on the determination result. On the other hand, a warning signal (s2) can be output.
Then, the warning signal (s2) output from the passage permission / inhibition determining means 13 indicates, for example, “Return” to the crossing passer B before the barrier rod 4 is lowered by the barrier rod elevator 5 after the alarm device 2 is activated. ”Or“ crossover ”can be displayed as characters, or displayed as characters or voice (step 16, step 19), and when the crossing person B determines that crossing is difficult, Along with the warning, a train control signal (s1) for decelerating the train A can be output (step 17).

In addition to this, when the crossing passer B determines that it is difficult to cross before the operation of the alarm device 2 based on the warning signal (s2) output from the passage permission / inhibition determination unit 13, the train A is approaching. A train control signal (s1) for decelerating the train can also be output (step 12).
In addition, in the passage permission / inhibition judging means 13, when the crossing passer B still exists in the crossing 1 after the barrier crossing 4 is lowered by the crossing lift 5, the train travel data (a) and the passing person movement data ( b), the possibility of collision with train A is determined, and if it is determined that there is a possibility of collision, a train control signal (s1) for emergency stop of train A is output (step 23). When it is determined that there is no possibility, a warning signal (s2) can be output to the crossing passer B (step 24).
In other words, in the monitoring system and monitoring program for a level crossing person B according to this embodiment, a pedestrian crossing a level crossing (especially an elderly person, a disabled person, a bicycle, a motorcycle or a motor vehicle) is driven while the train A is approaching. People who push bicycles, those who push bicycles, senior car users, etc.) can be provided with appropriate information not to be trapped in the level crossing 1 and can further enhance the safety of the railway. Become.

In addition, although the track | line R shown by this embodiment is a single line, you may apply to the track | line R of a multiple line or multiple lines or more. At that time, the train A is connected to the train control signal (s1) and the display means 20, 21 with respect to the train A based on the relationship between the approaching track R and the traveling direction of the crossing passer B (arrow (b) direction). On the other hand, it is preferable to output a warning signal (s2) for displaying "Please hurry back" or "Hurry to cross".
Further, when there are a plurality of level crossing passers B in the level crossing 1, the possibility of collision with the train A is individually determined and comprehensively determined, and the train control signal (s 1) for the train A is determined. A warning signal (s2) for displaying “please hurry back” or “please hurry” should be output to the display means 20, 21.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

  The present invention is a technology relating to railroad crossing security in which the safety of a railway is improved by monitoring the number of people passing through a railroad crossing.
