Description

Technical Field

[0001] This invention relates to the field of port and shipping information technology, specifically to a device and method for detecting safe passage of ships through locks. Background Technology

[0002] With the development of inland waterway transportation, the safety issues of ships passing through locks are becoming increasingly serious.

[0003] Current technology typically uses cameras to acquire vessel passage information, and operators then issue manual warnings based on this information. However, manual warnings are inefficient and cannot ensure the safety of lock equipment operation and vessel passage, making them prone to accidents. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for detecting safe passage through locks of ships, which can solve or partially solve the problems existing in the prior art.

[0005] To achieve the above objectives, embodiments of the present invention provide a ship safety lock passage detection device, which includes a ship position and speed monitoring module, a lock no-stopping monitoring module, and a mooring hook monitoring module.

[0006] The vessel position and speed monitoring module is used to detect the position, speed, and berthing status of the vessel to be passed through the lock. When the vessel to be passed through the lock exceeds the preset position and / or preset speed, a safety warning is issued.

[0007] The lock no-stopping monitoring module is installed at the upstream / downstream lock head and includes a no-stopping status acquisition unit. The no-stopping status acquisition unit is used to detect the no-stopping line section status of the lock chamber before the lock gate is closed / opened after the vessel intending to pass through the lock has completed entering the lock. It provides safety reminders to vessels intending to pass through the lock that have crossed the no-stopping line.

[0008] The mooring hook monitoring module, located inside the lock chamber, includes a mooring hook status detection unit. This unit detects the mooring completion status of the mooring hook when a vessel intending to pass through the lock enters and berths. It then provides safety alerts to vessels with abnormal mooring completion statuses.

[0009] When the mooring completion status of the vessel to be passed through the lock is abnormal, a signal prohibiting water supply will be sent to the adjacent lock head to prevent the adjacent lock head from opening its valves to supply water.

[0010] Optionally, the ship safety lock passage detection device further includes: a gate seam closure monitoring module installed at the gate;

[0011] The gate closure monitoring module includes a gate closure acquisition unit, which is used to detect the alignment status of the gate when the vessel intending to pass through the lock enters and berths. If the alignment status of the gate is abnormal when it is closed, a safety warning will be issued.

[0012] Optionally, the gate closure monitoring module also includes a safety interlock control unit, which sends a signal to prohibit water supply to the adjacent gate head when the alignment state is abnormal when the gate is closed, so as to prevent the adjacent gate head from opening the valve to supply water.

[0013] Optionally, the alignment status of the gate at the end of closing can be determined by detecting the gate gap and misalignment distance.

[0014] Optionally, the lock no-stopping monitoring module further includes: a no-stopping line indicator unit, used for indicating the position of the no-stopping line section and indicating whether a vessel has crossed the line.

[0015] Optionally, when the lock no-stopping monitoring module detects that the vessel intending to pass through the lock has crossed the no-stopping line, it sends a signal to the lock gate activation device to prevent the gate from being activated.

[0016] Optionally, the vessel position and speed monitoring module is installed at the upstream / downstream lock head, lock chamber, and pilotway.

[0017] Optionally, the mooring completion status of the mooring hook includes: whether the vessel intending to pass through the lock is moored and whether the mooring hook is used correctly;

[0018] The mooring hook monitoring module also includes a mooring hook identification and indication unit, which is used to indicate the color of the mooring hook applicable to the vessel intending to pass through the lock according to the lock passage plan.

[0019] Accordingly, embodiments of the present invention also provide a method for safe passage of ships through locks, the method comprising:

[0020] Monitor the position of vessels intending to pass through the lock;

[0021] When the monitoring shows that the vessel intending to pass through the lock has completed entering the lock, before the lock gate is closed / opened, the state of the no-stopping line section in the lock chamber is detected, and a safety warning is given to the vessel intending to pass through the lock that has crossed the no-stopping line.

[0022] When the vessel intending to pass through the lock is detected to have entered and berthed, the mooring hook status is checked, and a safety warning is issued to the vessel intending to pass through the lock if the mooring status is abnormal.

[0023] Optionally, the method for detecting safe passage of ships through locks further includes:

[0024] When the vessel intending to pass through the lock is detected to have entered and berthed, the alignment status of the gate at the end of closing is checked. If the alignment status at the end of closing the gate is abnormal, a safety warning is issued.

[0025] In this embodiment of the invention, a vessel position and speed monitoring module is used to detect the position of a vessel intending to pass through the lock in real time. When a vessel is detected to have crossed the no-stopping zone and entered the upstream or downstream lock head before the lock gate is fully open, the lock no-stopping monitoring module detects the state of the no-stopping line section in the lock chamber, issues a boundary crossing warning, and prohibits the gate from opening or closing to prevent the gate from colliding with a vessel that has entered the no-stopping zone. When a vessel is detected to have entered the lock chamber, the mooring hook monitoring module detects the mooring completion status of the mooring hook, enabling the mooring hook to provide a reaction force to control the vessel's movement and prevent it from colliding with the lock gate or lock wall. By cooperating with the vessel position and speed monitoring module, the lock no-stopping monitoring module, and the mooring hook monitoring module, the safety of vessel passage through the lock can be comprehensively guaranteed, and the efficiency of lock passage can be improved.

[0026] Other features and advantages of the embodiments of the present invention will be described in detail in the following detailed description section. Attached Figure Description

They are used together with the following detailed description to explain the embodiments of the present invention, but do not constitute a limitation thereof. In the drawings:

[0031] Figure 4 This is a flowchart of a method for safe passage of ships through locks provided in an embodiment of the present invention. Detailed Implementation

[0032] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0033] Figure 1 This is a structural block diagram of a ship safety lock passage detection device provided in an embodiment of the present invention.

[0034] like Figure 1As shown, the ship safety lock passage detection device includes: a ship position and speed monitoring module, a lock no-stopping monitoring module, and a mooring hook monitoring module;

[0035] The vessel position and speed monitoring module is used to detect the position, speed, and berthing status of the vessel to be passed through the lock. When the vessel to be passed through the lock exceeds the preset position and / or preset speed, a safety warning is issued.

[0036] The lock no-stopping monitoring module is installed at the upstream / downstream lock head and includes a no-stopping status acquisition unit. The no-stopping status acquisition unit is used to detect the no-stopping line section status of the lock chamber before the lock gate is closed / opened after the vessel intending to pass through the lock has completed entering the lock. It provides safety reminders to vessels intending to pass through the lock that have crossed the no-stopping line.

[0037] The mooring hook monitoring module, located inside the lock chamber, includes a mooring hook status detection unit. This unit detects the mooring completion status of the mooring hook when a vessel intending to pass through the lock enters and berths. It then provides safety alerts to vessels with abnormal mooring completion statuses.

[0038] When the mooring completion status of the vessel to be passed through the lock is abnormal, a signal prohibiting water supply will be sent to the adjacent lock head to prevent the adjacent lock head from opening its valves to supply water.

[0039] When the vessel position and speed monitoring modules located at the upstream / downstream lock heads detect the vessel's position, it indicates that the vessel intending to pass through the lock is currently passing through the upstream / downstream lock heads and the lock gates have not yet opened. At this time, the vessel no-stopping monitoring modules located at the upstream / downstream lock heads detect whether the vessel has entered the no-stopping zone between the lock gate and the no-stopping line. If the vessel crosses the no-stopping zone, a safety warning is issued.

[0040] For example, the vessel no-stopping monitoring module can detect the status of the no-stopping line section in the lock chamber using a camera. The camera's installation position can be adjusted according to upstream and downstream, left and right lock walls, and high and low water levels. The camera provides continuous, all-around, three-dimensional monitoring of the no-stopping area of ​​the lock, determining whether a vessel intending to pass through has crossed the no-stopping line and entered the no-stopping area. Alternatively, the vessel no-stopping monitoring module can also detect the status of the no-stopping line section in the lock chamber using a radar detection unit. This radar detection unit can then detect whether a vessel intending to pass through has crossed the no-stopping line and entered the no-stopping area.

[0041] By using a vessel no-stopping monitoring module to detect whether a vessel has crossed the no-stopping line and entered the no-stopping area, it can ensure that vessels maintain a safe distance from the lock equipment and facilities during the process of entering the lock, moving vessels, and berthing while waiting for water to be pumped, thus avoiding collisions that could damage the lock equipment and facilities or the vessels.

[0042] Furthermore, when the vessel position and speed monitoring module installed in the lock chamber detects the vessel's position, it indicates that the vessel intending to pass through the lock has entered the lock chamber. At this time, the mooring hook monitoring module checks whether the vessel intending to pass through the lock is moored and whether the mooring hook is being used correctly, and provides safety warnings to vessels intending to pass through the lock whose mooring completion status is abnormal.

[0043] For example, the mooring completion status can be detected by a stress sensor in the mooring hook monitoring module. This stress sensor can be installed on the lock mooring hook to determine whether the vessel intending to pass through the lock is moored and whether the mooring hook is being used correctly by detecting the magnitude of the tension on the mooring hook.

[0044] By using a mooring hook monitoring module to detect whether a vessel intending to pass through the lock is moored and whether the mooring hook is being used correctly, it can ensure that when a vessel is in the lock chamber or pilotway, the force generated by the vessel's movement is transmitted to the mooring hook through the mooring rope. The mooring hook then provides a reaction force to control the vessel's movement and prevent it from colliding with the lock gate or lock wall.

[0045] In the preferred embodiment, Figure 2 This is a structural block diagram of a ship safety lock passage detection device according to another embodiment of the present invention. In addition to the ship position and speed monitoring module, the lock no-stopping monitoring module, and the mooring hook monitoring module, the ship safety lock passage detection device may also include a gate seam closing monitoring module installed at the gate. The gate seam closing monitoring module may include a gate seam closing acquisition unit and a safety interlock control unit.

[0046] When the vessel position and speed monitoring module installed in the lock chamber detects that a vessel has entered and berthed in place, the gate seam closing acquisition unit detects the alignment status of the gate upon final closure. This includes detecting the gate seam and misalignment distance to determine if the alignment status is normal. If the alignment status is abnormal, a safety warning is issued. The safety interlock control unit can send a signal prohibiting water transport to adjacent lock heads when the alignment status is abnormal upon final closure, thus preventing water transport from adjacent lock heads.

[0047] For example, the gate alignment acquisition unit can detect the centering status of the gate when it is fully closed by monitoring the gate gap and misalignment distance through video images to determine whether it is aligned. Alternatively, photoelectric sensors can also be used to detect the gate gap and misalignment distance to determine alignment. Specifically, the photoelectric sensor can be placed on a target on the V-shaped gate. The target receives and reflects the laser emitted by the photoelectric sensor. The target and the photoelectric sensor together form the gate alignment acquisition unit, which converts the gate gap situation into the relationship between the photoelectric sensor and the target. Detecting the centering status of the gate when it is fully closed using the gate alignment acquisition unit ensures the accuracy and safety of the gate closure and eliminates safety problems caused by incomplete gate closure.

[0048] In this embodiment of the invention, a vessel position and speed monitoring module is used to detect the position of a vessel intending to pass through the lock in real time. When a vessel is detected to have crossed the no-stopping zone and entered the upstream or downstream lock head before the lock gate is fully opened, the lock no-stopping monitoring module detects the state of the no-stopping line section in the lock chamber, provides a boundary crossing warning, and prohibits the opening and closing of the lock gate to prevent the gate from colliding with the vessel that has entered the no-stopping zone. When a vessel is detected to have entered the lock chamber, the mooring hook monitoring module detects the mooring completion status of the mooring hook, enabling the mooring hook to provide reaction force to control the vessel's movement and prevent it from colliding with the lock gate and lock wall. When the mooring hook monitoring module detects that the mooring is normal, the gate closure monitoring module detects the centering status when the gate is fully closed, eliminating safety issues caused by the gate not being fully closed. The various modules of the ship safety lock passage device are not independent of each other. The position detection results of the ship position and speed monitoring module are the trigger conditions for the lock prohibition monitoring module, the mooring hook monitoring module, and the gate closure monitoring module. When the ship is at the upstream / downstream lock head, the lock prohibition monitoring module is triggered to start working. When the ship is in the lock chamber, the mooring hook monitoring module is triggered to start working. When the ship is in the lock chamber and is berthed normally, the gate closure monitoring module is triggered to start working. This avoids the various modules of the ship safety lock passage device from being in a working state all the time, which would result in huge energy consumption.

[0049] In another preferred embodiment, Figure 3 This is a structural block diagram of a ship safety lock passage detection device according to another embodiment of the present invention. The ship safety lock passage detection device includes: a ship position and speed monitoring module, a lock no-stopping monitoring module, and a mooring hook monitoring module. The lock no-stopping monitoring module includes a no-stopping status acquisition unit and a no-stopping marking indication unit. The no-stopping status acquisition unit is used to detect the state of the no-stopping line section of the lock chamber before the lock gate closes / opens after the ship intending to pass through has entered the lock, and to provide safety warnings to ships intending to pass through that have crossed the no-stopping line. The no-stopping marking indication unit is used to indicate the position of the no-stopping line section. When the lock no-stopping monitoring module detects that the ship intending to pass through has crossed the no-stopping line, it sends a signal prohibiting the opening of the lock gate to the gate opening and closing device to prevent the gate from opening.

[0050] For example, the no-stopping marking indicator unit can indicate the position of the no-stopping line section through warning lights, laser markings, etc., thereby reminding the ship's driver of the location where the ship is prohibited from stopping and reducing the risk of the ship entering the no-stopping area.

[0051] In another preferred embodiment, Figure 3This is a structural block diagram of a ship safety lock passage detection device according to another embodiment of the present invention. The ship safety lock passage detection device includes: a ship position and speed monitoring module, a lock no-stopping monitoring module, and a mooring hook monitoring module. The mooring hook monitoring module includes a mooring hook status detection unit and a mooring hook identification unit. The mooring hook status detection unit is used to detect the mooring completion status of the mooring hook when a ship intending to pass through the lock enters and berths, to provide a safety warning to the ship intending to pass through the lock if the mooring completion status is abnormal, and to send a signal prohibiting water supply to adjacent lock heads when the mooring completion status of the ship intending to pass through the lock is abnormal, so as to prevent adjacent lock heads from opening valves to supply water. The mooring hook identification unit is used to indicate the color of the mooring hook applicable to the ship intending to pass through the lock according to the lock passage plan.

[0052] For example, the mooring hook indicator unit can synchronously indicate the berthing position of the vessel through on-site display color, screen display color, and three-dimensional simulation color, ensuring that the vessel berths and completes mooring in the correct position.

[0053] Accordingly, this invention also provides a method for safe passage of ships through locks.

[0058] S430: When the vessel to be passed through the lock is detected to have entered the lock and berthed, the mooring hook mooring completion status is detected, a safety warning is given to the vessel to be passed through the lock if the mooring completion status is abnormal, and when the mooring completion status of the vessel to be passed through the lock is abnormal, a signal to prohibit water supply is sent to the adjacent lock head to prevent the adjacent lock head from opening the valve to supply water.

Optionally, if the alignment status is abnormal when the lock gate is fully closed, a signal prohibiting water supply can also be sent to adjacent lock heads to prevent adjacent lock heads from opening valves to supply water.
