Description

  The present invention relates to an emergency closure control system for waterproof equipment.

  The Indonesia-Sumatra Earthquake (M9.0) that occurred in December 2004 exceeded 200,000 people who were missing, most of which were due to the tsunami after the earthquake. Moreover, the tsunami-affected areas do not stop around Indonesia, but extend to far-away India, Sri Lanka, and eastern Africa. In the city of Bandachu on Sumatra Island, which is close to the epicenter, a tsunami disaster investigation report was reported that a huge power generation ship with a displacement of 2500 tons was launched in a residential area about 2km inland from the coast. Furthermore, the serious situation that agricultural land etc. cannot be used for a long time due to the inundation of seawater by tsunami.

  It is well known that even in our country, earthquakes and tsunamis associated therewith are frequent and many damages have occurred.

  In particular, in recent years, the occurrence of large earthquakes has been predicted with high probability in each region, but there is no prediction of when, where, and at what scale, and once it occurs, it will be instantaneous. An earthquake of magnitude M8 to M9 occurs within the time that can be said, and the tsunami that accompanies it will be pushed to the coast after several minutes to tens of minutes.

  And if an earthquake and the accompanying tsunami occur, it is clear that if the tsunami goes up the river, it will cause serious human and economic damage to the river basin. Rainwater and drainage from the water gates and basins for sluices installed within the wave-affected area, movable weirs that cross the river in the river, or through the embankment to take water into the farmland Reinforcement work is being carried out on the locks that are installed in the waterways to allow them to flow into the river. However, even if the sluice is reinforced, it goes without saying that it is meaningless if the sluice is not completely closed before the tsunami rushes to the sluice.

  Therefore, in the tide gate opening and closing system having the function of automatically closing and closing the tide sluice gate in the event of an emergency, automatic sudden descent and semi-closed control means (a) for temporarily controlling the tide sluice gate to be in a semi-closed state at the time of automatic sudden descent full closing control, Means (b) for confirming that there is no sluice passage ship when the tide gate is in a semi-closed state, and sudden descent full-closed control for controlling the tide sluice gate to a fully closed state when there is no sluice passage ship by this confirmation means A sea tide gate opening and closing system comprising means (c) has been proposed (see Patent Document 1).

  In this patent document 1, the following description is made as sluice control in the conventional tide sluice gate opening and closing system.

  10A is a block diagram of the tide gate opening and closing system, FIG. 10B is a flowchart of the tide lock closing control by normal operation, and FIG. 10C is a flowchart of the tide lock closing control in an emergency. is there.

  First, at the time of closing control of the tide sluice gate by normal operation, the operator confirms safety when closing the tide sluice gate 41 with the ITV monitor or the like of the tide sluice gate monitoring device 40 [step in FIG. S31], a sluice gate descent command is issued to the tide gate control device 42 by manual operation [step S32 in FIG. 10B]. When the tide lock control device 42 receives the sluice gate descent command from the tide lock monitoring device 40, the tide lock gate 41 is lowered with the drive of a rotating lamp or the like until the lower limit switch (LS) 43 detects the door lower limit state. Close [Steps S33 to S36 in FIG. 10B].

  On the other hand, at the time of closing control of the tide sluice gate in an emergency, the tide sluice gate monitoring device 40 receives a warning command such as a tsunami, storm surge, wave, or the like, or a detection signal associated with the occurrence of an earthquake exceeding a predetermined seismic intensity from the seismometer 44. By receiving [Step S41 of FIG. 10C], a sluice gate descent command is uniquely issued to the tide gate control apparatus 42 [Step S42 of FIG. 10C]. When the tide sluice gate control device 42 receives a sluice gate descent command from the tide sluice gate monitoring device 40, the tide sluice gate 41 is lowered by driving a rotating lamp or the like until the lower limit switch (LS) 43 detects the door lower limit state. Close [Steps S43 to S46 in FIG. 10C].

  And in patent document 1, in such conventional tide gate lock control, the tide lock control in an emergency has no problem in terms of the tide effect, but a problem remains in terms of safety. At the time of sluice closing control, when there is a ship navigating through the sluice gate, the sluice gate where the navigating ship suddenly descends cannot be avoided, and it touches or collides with the sluice gate, damages the ship, sluice gate, etc. It is said that there is a risk of uncontrollability. In addition, at the time of closing control of the tide gates in an emergency, measures such as warning lights etc. are used to notify the surrounding navigation vessels of the sluice gates. It is said that it is necessary to construct a system in consideration of the occurrence of the scandals described above in order to further improve the performance.

  Therefore, in Patent Document 1, when the tide sluice gate is suddenly lowered and controlled by the above-mentioned means (a) to (c), the automatic tide sluice gate is controlled by the automatic sudden descent and semi-closed control once. By interposing a means for confirming the presence / absence of a ship passing through a sluice, it is possible to reliably avoid scandals such as damage to the ship, sluice, etc., inability to navigate the ship, and inability to control the sluice. It is characterized by constructing an open / close system.

  That is, FIG. 11 is a block diagram of the tide gate opening / closing system in the embodiment of Patent Document 1, and FIG. 12 is a flowchart of the tide gate opening / closing system.

  The tide sluice gate automatic opening / closing device 46 receives a warning instruction such as a tsunami, a storm surge, a wave, etc. via the tide sluice gate monitoring device 47 (step S51 in FIG. 12), or a detection associated with the occurrence of an earthquake exceeding a predetermined seismic intensity from the seismometer 48. When the signal is received, a sluice gate descent command is sent to the tide lock control device 49 (step S52 in FIG. 12).

  When the tide sluice gate control device 49 receives a sluice gate descent command from the tide sluice gate automatic opening / closing device 46, the tide sluice gate 50 is controlled to drive the descent of the tide gate 50 with the driving of a rotating lamp or the like (steps S53, 54, and 55 in FIG. 12). .

  Further, at this time, the tide gate control device 49 sends the sluice position detection signal input from the sluice position detection device 51 and the sluice state signal input from the door lower limit switch (LS) 52 to the tide gate automatic opening / closing device 46. Deliver.

  The tide gate automatic opening / closing device 46 monitors the sluice position detection signal input via the tide gate control device 49, and the sluice position detection signal indicating the door half-open position from the sluice gate position detection device 51 via the tide gate control device 49. In response, a door descent stop command is sent to the tide gate control device 49.

  When the tide sluice gate control device 49 receives a door descent stop command from the tide sluice gate automatic opening / closing device 46, the tide sluice gate control device 49 stops the door descent drive of the tide gate 50. As a result, the tide gate 50 is kept in a half-closed state. This half-closed state of the door is notified to the tide gate monitoring device 47 by the tide gate automatic opening / closing device 46 (step S56 in FIG. 12).

  When the operator who is performing the monitoring work with the tide sluice gate monitoring device 47 recognizes the half-closed state of the tide sluice gate 50, the tide sluice gate 50 is displayed from the display image of the ITV monitor displaying the image data of the ITV camera 53. Is confirmed (step S57 in FIG. 12), and a sluice gate descent command is sent again to the tide gate automatic opening / closing device 46 (step S58 in FIG. 12).

  When the tide sluice gate control device 49 receives a sluice gate sudden drop command from the tide sluice gate automatic opening / closing device 46, the tide sluice gate 50 is controlled to drive the tide sluice gate 50 with a drive of a rotating lamp or the like (steps S59, 60, 61 in FIG. 12). .

  When the tide sluice gate automatic opening / closing device 46 receives a state signal indicating the door fully closed state from the door lower limit switch (LS) 52 via the tide sluice gate control device 49, the tide sluice gate control device 49 issues a door descent stop command. Send it out.

  When the tide sluice gate control device 49 receives a door descent stop command from the tide sluice gate automatic opening / closing device 46, the tide sluice gate control device 49 stops the door descent drive of the tide gate 50. Thereby, the tide lock 50 is in a fully closed state. The tide sluice gate automatic opening / closing device 46 notifies the tide sluice gate monitoring device 47 of this fully closed state of the tide gate, and the emergency close-down control operation of the sluice gate in an emergency is completed (step S62 in FIG. 12).

  In this way, when an earthquake or tsunami occurs, all the sluices that are subject to monitoring and control are automatically closed to a certain height (about several meters from the water level) by remote control, and image recognition such as an ITV monitor is performed. After confirming that there are no obstacles such as people, ships, things, etc., it has the function of fully closing the sluice gate, so it is possible to reliably avoid the occurrence of scandals associated with the automatic closing and closing control of the tide sluice gate. It is said that the automatic sudden descent full-closed control with high can be achieved.

  In addition, as a reason for temporarily stopping the tide lock in the semi-closed state, in the opinion, etc., `` In consideration of the existence of ships passing or going through the tide lock, the tide lock is temporarily closed. By doing so, it was possible to close it as soon as possible and to ensure safety against ship passage. "

Patent Document 1 seems to be a perfect tide gate opening and closing system for a desktop plan.
Japanese Patent No. 3695939

  However, the tide sluice gate opening and closing system of Patent Document 1 has a fatal defect as a real problem when faced with an earthquake and a tsunami associated therewith.

  In the event of an earthquake or tsunami, all sluice gates that are subject to monitoring and control are automatically closed to a semi-closed state by remote control, and there are no obstacles such as people, ships, or objects by image recognition using an ITV monitor or the like. After confirming this, it is necessary to fully close the sluice gate, that is, an artificial factor such as image recognition by an operator such as an ITV monitor is essential.

  For example, it is assumed that a large earthquake of M8 to M9 occurs and a tsunami that accompanies it hits the sluice gate after about 10 minutes.

  First, no matter how much the monitoring system is 24 hours, it is normal for the operator to also perform other tasks, so there is no way to sit in front of the ITV monitor etc. for 24 hours. In addition, immediately after the earthquake, there is a lot of confusion such as the scattering of fixtures and equipment in the workplace where ITV monitors are installed, so within 10 minutes from the occurrence of the earthquake until the tsunami breaks through the semi-closed sluice. Furthermore, there is no guarantee that the operator can arrive without difficulty in front of the ITV monitor or the like.

  Second, even if the operator can arrive in front of the ITV monitor before the tsunami breaks through the semi-closed sluice, it may not be in time for the tsunami to break through the semi-closed sluice. Even when such a ship can be confirmed by image recognition using an ITV monitor or the like, there is no guarantee that the operator can ignore the ship and control the sluice in a fully closed state.

  And if the tsunami breaks through a semi-closed sluice, even if you try to fully control the sluice after it breaks, the tsunami water pressure makes it impossible to fully close the sluice. Will cause great human and economic damage to the basin.

  The present invention has been made to solve the above-mentioned problems. After looking directly at the actual problems, the safety of people near the waterproofing facilities and the great human and economic damages such as river basins. The purpose is to provide an emergency closure control system for waterproofing equipment that takes into account the public benefit of mitigation.

  In addition, seismometers installed by the Japan Meteorological Agency etc. seismic S-waves (main oscillation ... see E in Fig. 7) about 7 seconds later, mainly the presence or absence of tsunamis, the magnitude of the tsunami (waves The emergency earthquake information receiving device 16 automatically receives the second tsunami information including the tsunami arrival time, which indicates when and in what area the tsunami of which size will reach.

  The earthquake / tsunami information received by the emergency earthquake information receiving device 16 may be processed by a control circuit (computer or the like) incorporated in the emergency earthquake information receiving device 16 or the like, and the tsunami may rush to the sluice 1 of the river J. If there is a sluice gate 1 if it does not close, it is pre-programmed whether it will reach human or economic damage to the river J basin and when it will arrive. Judgment based on the information.

  And when it is judged that the tsunami does not rush to the sluice 1 of the river J, even if it rushes, if it is judged that it is a scale that does not cause human and economic damage to the basin, the emergency closure of the sluice 1 described below Do not operate the control system. Thereby, since it is not necessary to operate the emergency closure control system of the sluice 1 of the river J, unnecessary uneasiness is not given to the ship and people near the sluice. It is also possible to display or broadcast a message such as “Do not urgently close the sluice 1 because there is no tsunami due to the earthquake” on the electric display boards 21A to 21C and the speaker 22 described later.

  On the other hand, when it is judged that the tsunami has reached the sluice gate 1 of the river J in about 10 minutes and causes human and economic damage to the basin, the emergency closure control system for the sluice gate 1 described below is operated. .

  In step S2, an emergency close command for the sluice 1 is automatically issued from the emergency earthquake information receiving device 16 or the like to the instrumentation side instrument panel 24 and the operation panels 6L and 6R via a signal cable (or wirelessly). become.

  (A) About 10 minutes before the arrival of the tsunami, that is, about 10 minutes before the emergency closing of the sluice 1, first of the first about 2 minutes (the first predetermined time), Actions will be made.

  In step S3, the revolving lamps 20A to 20F are turned on and are continuously lit and rotated. The lighting / rotation of the rotating lamps 20A to 20F is continued until the gates 2 and 3 are fully opened again after the tsunami has passed [the columns (1) and (2) of the rotating lamps 20A to 20F in FIG. (See arrow).

  The bell 23 is turned on and keeps ringing (for example, repeating for 5 seconds and stopping for 20 seconds) (see (1) and (2) in the column of the bell 23 in FIG. 7 and white arrows). This bell 23 keeps ringing until the emergency closing control of the gates 2 and 3 is completed.

  The electric display boards 21A to 21C are turned on, and the characters “Sluice closed” are displayed blinking. The blinking display of the electric display boards 21A to 21C is continued until about 1 minute (about 60 seconds) before the emergency closing of the sluice 1 [the hatched arrow with (1) in the column of the electric display boards 21A to 21C in FIG. reference〕.

  After about 5 seconds, the speaker 22 was turned on, “An earthquake occurred. There is a risk of a tsunami, so this sluice will be closed urgently. Please do not approach it because it is dangerous. Please evacuate promptly "for about 20 seconds (see (1) in the column of speakers 22 in FIGS. 7 and 8).

  Subsequently, the message “The sluice shuts down urgently.” “Dangerous. Please evacuate immediately.” Is broadcast repeatedly in about 35 seconds [(2 in the column of speakers 22 in FIGS. 7 and 8). (See (3)).

  (B) Next, the next operation is performed for the next about 1 minute (about 60 seconds) in the first about 2 minutes.

(60 seconds before closing the sluice)
The electric display boards 21A to 21C repeatedly display the characters “sluice gate closed” and “60 seconds ago” alternately (see (2) in the column of the electric display boards 21A to 21C in FIG. 7).

  The speaker 22 broadcasts the message “60 seconds ago” (see (4) in the column of the speakers 22 in FIGS. 7 and 8).

(50 seconds before sluice closing)
The electric display boards 21A to 21C repeatedly display the characters “Sluice closed” and “50 seconds ago” alternately (see (3) in the column of the electric display boards 21A to 21C in FIG. 7).

  The speaker 22 broadcasts the message “50 seconds ago” (see (5) in the column of the speakers 22 in FIGS. 7 and 8).

(40 seconds before sluice closing)
The electric display boards 21A to 21C repeatedly display the characters “sluice gate closed” and “40 seconds ago” alternately (see (4) in the column of the electric display boards 21A to 21C in FIG. 7).

  The speaker 22 broadcasts the message “40 seconds ago” (see (6) in the column of the speakers 22 in FIGS. 7 and 8).

(30 seconds before sluice closing)
The electric display boards 21A to 21C repeatedly display the characters “sluice gate closed” and “30 seconds ago” alternately (see (5) in the column of the electric display boards 21A to 21C in FIG. 7).

  The speaker 22 broadcasts the message “30 seconds ago” (see (7) in the column of the speakers 22 in FIGS. 7 and 8).

(20 seconds before sluice closure)
The electric display boards 21A to 21C repeatedly display the characters “sluice gate closed” and “20 seconds ago” alternately (see (6) in the column of the electric display boards 21A to 21C in FIG. 7).

  The speaker 22 broadcasts a message “20 seconds ago” (see (8) in the column of the speakers 22 in FIGS. 7 and 8).

(10 seconds before sluice closing)

  The speaker 22 broadcasts the message “10 seconds ago” (see (9) in the column of the speakers 22 in FIGS. 7 and 8).

  The speaker 22 broadcasts a message every second between 60 seconds and 10 seconds before closing the sluice gate, then “Emergency shuts down the sluice.” “Dangerous. Please evacuate immediately. "[2] (3) in the column of the speakers 22 in FIGS. 7 and 8].

  (C-1) Then, after the first about 2 minutes have passed since about 10 minutes before the arrival of the tsunami, the following operation is performed.

  In step S4, a sluice gate emergency closure start command is automatically issued to the electric wire rope type switching devices 5L and 5R, and in step S5, the sluice gate 1 is started to be urgently closed.

  When the emergency closing of the sluice 1 is started, the left bank gate 2 and the right bank gate are operated by the electric wire rope type opening / closing devices 5L and 5R without operating the respective operation panels 6L and 6R as in the normal time. 3 means that emergency closing control is automatically performed at a rapid speed of about 1.5 m / min, and it takes about 4.5 minutes (about 3 times the normal speed) from full opening to full closing. become.

  In step S6, the video monitor terminal monitor 13B incorporates the video of the ship 10 passing through the gate openings 2A and 3A of the left bank gate 2 and the right bank gate 3 that are continuously monitored by the monitoring television cameras 11A to 11D. The image processing circuit automatically performs image processing and analysis, and if it is determined that the ship 10 is not passing (No), the emergency closing is continued as it is. After confirming (about 5.5 minutes after the first about 2 minutes have passed since about 10 minutes before the arrival of the tsunami), a stop command is issued to each switching device 5L, 5R in step S8, and each switching device The emergency closing control is completed by stopping 5L and 5R.

  Here, adding the first 2 minutes 10 minutes before the arrival of the tsunami and 4.5 minutes of emergency closure control, it is about 6.5 minutes, leaving a margin of about 3.5 minutes until the arrival of the tsunami. Will be.

  In addition, in Step S4, the sluice emergency closing start command is automatically issued, so that the electric display boards 21A to 21C continue to display the characters “being closed” until the sluice 1 is fully closed [ (Refer to (8) → (11) in the column of the electric display boards 21A to 21C in FIG. 7). The speaker 22 repeatedly broadcasts the message “dangerous” and “the sluice is closed” until the sluice 1 is fully closed [(10) → (See (11)). The indication of “closed” by the electric display boards 21A to 21C and the broadcast of “dangerous” and “the sluice is closed” by the speaker 22 are fully opened after the tsunami has passed. It is preferable to continue until.

  On the other hand, if it is determined in step S6 that the ship 10 is passing (Yes), the emergency closure is interrupted in step S9, and about 1 minute (second predetermined time) elapses in step S10. wait.

  The electric display boards 21A to 21C repeatedly display the characters “DANGER” and “EVALUATION SEYO” alternately ([9) (9) between (8) → (11) in the column of the electric display boards 21A to 21C in FIG. 10)].

  Speaker 22 “Obstacles detected.” “Emergency closes soon. If you are near the sluice, please evacuate promptly.” “Forcibly close emergency after one minute.” “Danger Please evacuate immediately. ”“ It is 60 seconds ago ”“ It is 50 seconds ago ”“ It is 40 seconds ago ”“ It is 30 seconds ago ”“ It is 20 seconds ago ”“ It is 10 seconds ago ”“ Sluice is urgent The message “Closed” is broadcasted (see (12) → (17) in the column of the speakers 22 in FIGS. 7 and 8).

  Then, when about 1 minute has passed in step S10, emergency closure is resumed in step S11. Thereafter, the emergency closing control is completed through steps S7 and S8 as described above.

  Next, referring to the flowchart of the emergency closing control of the second embodiment in FIG. 6, the stage explanatory diagram of the emergency closing control in FIG. 7, and the broadcast example diagram of the speaker 22 in FIG. 8, the second embodiment of the sluice 1 The operation point of the emergency closing control system will be described.

  Steps S1 to S3 in FIG. 6 are the same as the flowchart of the emergency closing control of the first embodiment in FIG.

  (C-2) Then, after the first about 2 minutes have passed since about 10 minutes before the arrival of the tsunami, the next operation is performed.

  In step S14, the video of the ship 10 passing through the gate openings 2A and 3A of the left bank gate 2 and the right bank gate 3 that are continuously monitored by the monitoring television cameras 11A to 11D is incorporated into the video monitoring terminal monitor 13B. If the image processing circuit automatically processes and analyzes the image and determines that the ship 10 is not passing (No), in step S15, the electric wire rope type opening / closing devices 5L and 5R are instructed to start a sluice emergency closure. Is automatically issued, and in step S16, the emergency closing of the sluice 1 is started. After that, the emergency closing is continued in the same manner as the determination in Step S6 (No) and Steps S7 and S8 in the flowchart of the emergency closing control of the first embodiment in FIG. When a closing signal or timer (about 5.5 minutes after the first about 2 minutes have passed since about 10 minutes before the arrival of the tsunami) is confirmed, a stop command is issued to each switchgear 5L, 5R in step S18. The emergency closing control is completed by stopping each of the opening / closing devices 5L and 5R.

  On the other hand, if it is determined in step S14 that the ship 10 is navigating (Yes), the process waits until about 1 minute (second predetermined time) elapses in step S19.

  The electric display boards 21A to 21C repeatedly display the characters “DANGER” and “EVALUATION SEYO” alternately ([9) (9) between (8) → (11) in the column of the electric display boards 21A to 21C in FIG. 10)].

  Speaker 22 “Obstacles detected.” “Emergency closes soon. If you are near the sluice, please evacuate promptly.” “Forcibly close emergency after one minute.” “Danger Please evacuate immediately. ”“ It is 60 seconds ago ”“ It is 50 seconds ago ”“ It is 40 seconds ago ”“ It is 30 seconds ago ”“ It is 20 seconds ago ”“ It is 10 seconds ago ”“ Sluice is urgent The message “Closed” is broadcasted (see (12) → (17) in the column of the speakers 22 in FIGS. 7 and 8).

  Then, when about 1 minute has passed in step S19, in step S15, a sluice emergency closing start command is automatically issued to the electric wire rope type switching devices 5L and 5R, and thereafter, in steps S16 to S18 Thus, the emergency closing control is completed.

  In the case of the emergency closing control system for the sluice 1 as in the first and second embodiments, when an emergency signal of tsunami is received by the emergency earthquake information receiving device (receiving means) 16, first, the corresponding sluice (waterproof) (Equipment) An emergency signal notifying that the tsunami does not rush by judging whether or not it is an urgent signal notifying that the tsunami is rushing to the 1 by a control circuit (determination means) incorporated in the emergency earthquake information receiver 16 or the like When it is determined that the emergency closure information is not notified to the vicinity of the sluice 1 by the rotating lights (notification means) 20A to 20F or the like, unnecessary uneasiness is not given to the ship 10 or the person in the vicinity of the sluice 1. Even if the emergency closing information is not notified, it is possible to notify the information that the tsunami does not approach the sluice gate 1 and the information that the sluice gate 1 is not urgently closed. No need to worry about people around the sluice 1

  Further, when it is determined that the signal is an emergency signal notifying that the tsunami is approaching, the emergency closure information is notified by rotating lights 20A to 20F at least until the emergency closing of the sluice 1 is completed. It can be evacuated quickly.

  Then, in the emergency closure control system of the first embodiment of FIG. 5, if the emergency closure information is notified for about 2 minutes (first predetermined time), the ship 10 or a person has already evacuated from the vicinity of the sluice 1. Therefore, the emergency closure of the sluice 1 is started, and the presence of obstacles such as the ship 10 and people near the sluice 1 is detected by the monitoring television cameras (detection means) 11A to 11D during the emergency closure. If no obstacle is detected, the emergency closure is continued. Thereby, it is possible to prevent the tsunami or the like from coming inward of the sluice 1 with a margin.

  In addition, when an obstacle is detected during the emergency closing, the obstacle is evacuated while notifying the emergency closing information to the ship 10 etc. near the sluice 1 with the rotating lights 20A to 20F. The emergency closure is resumed after the emergency closure is interrupted until about 1 minute (second predetermined time) has passed until the tsunami is near enough. Thereby, obstacles, such as the ship 10 and a person, can evacuate from the vicinity of the sluice 1 to a safe place, and a tsunami or the like can be prevented from coming inward of the sluice 1 from the viewpoint of public benefit.

  Moreover, in the emergency closure control system of 2nd Embodiment of FIG. 6, if notification of emergency closure information is performed only for about 2 minutes (1st predetermined time) similarly to the emergency closure control system of 1st Embodiment, it will be waterproof. Although it can be inferred that people have already evacuated from the vicinity of the equipment, the presence of obstacles such as the ship 10 near the sluice 1 and humans is detected with the monitoring TV cameras (detection means) 11A to 11D. When no obstacle is detected, the emergency closing of the sluice 1 is started. Thereby, it is possible to prevent the tsunami or the like from coming inward of the sluice 1 with a margin.

  Moreover, when there is an obstacle detected, it is sufficient for the obstacle to evacuate while notifying the emergency closure information to the ship 10 near the sluice 1 with the rotating lights 20A to 20F etc. After waiting for about 1 minute (second predetermined time) until just before pushing, emergency closure is started. Thereby, while obstructions, such as a ship 10 and a person, can evacuate to the safe place from the sluice gate 1 vicinity, it can prevent from a public interest viewpoint that a tsunami etc. approach the inside of the sluice 1 in advance. .

  Emergency signals that adversely affect sluice 1 are not limited to tsunami information, but can prevent tsunamis, storm surges, and waves from invading sluice 1 by operating an emergency closure control system for storm surges and wave information. Can do.

  Furthermore, as an alerting | reporting means, in this embodiment, the electric display boards 21A-21C, the rotary lamps 20A-20F, the speaker 22, and the bell 23 are used, However, it is not restricted to this.

  The electric display boards 21A to 21C and the rotary lamps 20A to 20F can visually notify the emergency closing information, which is easy to understand even for people who are hard to hear, and the speaker 22 and the bell 23 are audibly notified of the emergency closing information. It is easy to understand even for people who are hard to see.

  Although not specifically shown, a remote place where the notification by the notification means does not reach if a radio for disaster prevention, for example, a radio installed on or brought into a ship or an emergency channel of a mobile phone is used. The emergency closure information can be notified to a ship or the like in the area.

  In addition, the electric light display boards 21A to 21C and the speaker 22 notify the time until the emergency closing (the time that can be withdrawn) while counting down, such as “60 seconds before” and “10 seconds before”, so that the emergency closing is performed. Since the time until is known in advance, obstacles such as the ship 10 and people can no longer approach the sluice gate 1 that is urgently closed, or the ship 10 etc. can pass through the sluice gate 1 within the time, and the safety is further improved. It becomes like this.

  Furthermore, the operator can check the obstacle image captured by the monitoring TV cameras 11A to 11D on the monitors 13A and 13B, and the image processing circuit (image processing means) incorporated in the image monitoring terminal monitor 13B can detect the obstacle. Since the presence / absence is automatically image-processed and analyzed, the sluice 1 can be automatically and urgently closed even when there is no operator due to confusion after the earthquake.

  The emergency closing control system is capable of detecting obstacles in combination with the fact that the sluice 1 can be automatically closed without any human factors by automatically performing it based on predetermined sequence control. When the tsunami is in contact with the ship 10 etc. in the vicinity of the sluice 1, it is sufficient for the obstacles to evacuate while notifying the time until the start of emergency closure, and after waiting until just before the tsunami rushes, Since it will be closed, it will be possible to prioritize greater public interest while giving due consideration to safety.

  In addition, by setting the predetermined time before the sluice gate 1 to be urgently closed to about 1 minute, obstacles such as the ship 10 and people can be sufficiently evacuated from directly below the gates 2 and 3 and the like of the sluice gate 1 to be urgently closed. It becomes possible to improve safety.

  In the above embodiment, it is assumed that a tsunami is brought to the sluice 1 of the river J about 10 minutes after the occurrence of the earthquake, and still about the first 2 minutes 10 minutes before the arrival of the tsunami and about 4. Adding 5 minutes is about 6.5 minutes, leaving a margin of about 3.5 minutes to reach the tsunami.

  Therefore, for example, if the sluice 1 is controlled to be urgently closed by about 1 minute before the arrival of the tsunami, the remaining about 2.5 minutes will be about 1 minute before the first about 2 minutes 10 minutes before the arrival of the tsunami. By adding to the minute or adding to about 1 minute when an obstacle is detected, each can be extended to about 3.5 minutes, so the notification time and the evacuation time will be longer, making safety more To improve.

  In addition, when the tsunami arrival time is about 20 minutes later because the epicenter is far away, the tsunami arrival time (emergency closure of the sluice gate 1) from about 20 minutes ago with the electric display boards 21A to 21C and the speaker 22 (Time) can be displayed and broadcast, so that the safety is further improved. As a result of such display and broadcasting, when the ship 10 or the like can be sure that the sluice 1 does not pass through the sluice 1 during the emergency closure of the sluice 1, the operator manually operates the push button box 17 for emergency closure, The sluice 1 can be urgently closed early. Furthermore, if there is sufficient time, it can be closed normally for about 12 to 13 minutes instead of emergency closing for about 4.5 minutes, so that safety is further improved.

  In the above-described embodiment, the predetermined time (second predetermined time) before the sluice gate 1 is urgently closed is about 1 minute, but is adjusted in the range of about 30 seconds to about 5 minutes in consideration of the tsunami arrival time. In addition, since the notification time and the evacuation time are increased by increasing the predetermined time, the safety is further improved.

  In the above embodiment, the rotating lamps 20A to 20F, the electric display boards 21A to 21C, the speaker 22, the bell 23, and the notification means such as the disaster prevention radio are used, but water is blown from the high pressure nozzle to the water surface near the water gate 1, Visual notification can also be made by blowing bubbles from the water in the vicinity of the sluice 1 or generating waves with a wave-making device to make the water surface abnormally ripple.

  In the above-described embodiment, the sluice 1 near the mouth of the river J is exemplified as the waterproofing facility. However, the movable dam 33 and the lock 30 may be used, and the tide sluice gate of the breakwater is also urgent from the public utility perspective. Close control can be done.

  In addition to waterproof gates 1 and Xiamen 30, waterproof facilities are not only waterproof shutters 31 at the entrances and exits of buildings such as factories and warehouses with high public interest or private interest, but also waterproofs at entrances and exits of subways and underground malls with high public interest. Similarly, the door 32 can be subjected to emergency closing control. In these cases, the notification content by the electric display board, the speaker, or the like may be simplified as compared with the case of the sluice 1.
