Description

Technical Field

[0001] This invention relates to the field of water transport technology, and in particular to a method and system for monitoring waterway passage through locks. Background Technology

[0002] Currently, water transport is an important component of the comprehensive transportation system, with advantages such as large transport capacity, small land occupation, and low energy consumption. It is a resource-saving and environmentally friendly mode of transportation, as well as a typical low-carbon mode of transportation.

[0003] In related technologies, the monitoring method for ships passing through locks in waterways is basically to use camera images to monitor the ships in the locks, and staff use the video monitoring information to schedule the ships. However, when there is fog or the lock is releasing water, a large amount of water mist is generated near the lock gates. This water mist severely affects the clarity of the images captured by the cameras. As a result, staff cannot accurately determine the ship's specific position and speed within the lock from the video captured by the cameras, making it impossible for staff to accurately and promptly schedule the ships.

[0004] Therefore, it is necessary to design a new method and system for monitoring waterway passage through locks to overcome the above problems. Summary of the Invention

[0005] This invention provides a waterway lock passage and navigation monitoring method and system to solve the problem in related technologies where water mist severely affects the clarity of images captured by cameras, thus making it impossible to accurately and timely complete the scheduling of ships.

[0006] Firstly, a waterway lock passage and navigation monitoring method is provided, which includes the following steps: acquiring the ship's speed and position information based on multiple sets of remote spotlights; accurately arranging the ship's entry into the lock according to the ship's position information to generate entry arranging information; calculating the ship's entry speed and entry route according to the entry arranging information; determining in real time whether the ship's speed information meets the entry speed and whether the route meets the entry route, and controlling the ship to enter the lock according to the calculated entry speed and entry route.

[0007] In some embodiments, the remote spotlights include fixed transmitters and fixed receivers, which are respectively positioned on both sides of the waterway. The acquisition of ship speed and position information based on multiple sets of remote spotlights includes: determining the ship's position information based on whether each fixed receiver receives light emitted by the fixed transmitters in the same set; and determining the ship's speed information based on the ship's position information and time at different times.

[0008] In some embodiments, the remote spotlights include fixed remote spotlights and mobile remote spotlights. The acquisition of ship speed and position information based on multiple sets of remote spotlights includes: acquiring the speed and position information of two adjacent ships entering the lock side by side based on multiple sets of fixed remote spotlights combined with multiple mobile remote spotlights located between two adjacent ships entering the lock side by side.

[0009] In some embodiments, the method of obtaining the speed and position information of two adjacent vessels entering the lock side-by-side based on multiple sets of fixed long-range spotlights combined with multiple mobile long-range spotlights located between two adjacent vessels entering the lock side-by-side includes: using the mobile long-range spotlights to emit or receive light, and using corresponding fixed long-range spotlights to receive or emit light; and determining the speed and position information of the two adjacent vessels entering the lock side-by-side based on the light reception status of the mobile long-range spotlights or the fixed long-range spotlights.

[0010] In some embodiments, the waterway lock passage and navigation monitoring method further includes: controlling a mobile long-range spotlight to move between two adjacent vessels along the lock entry direction; and using the mobile long-range spotlight positioned between two adjacent vessels along the lock entry direction for navigation.

[0011] In some embodiments, the remote spotlights include fixed remote spotlights arranged vertically on both sides of the gate. The real-time determination of whether the ship's speed information meets the entry speed and whether the navigation route meets the entry navigation route, and the control of the ship to enter the gate according to the calculated entry speed and entry navigation route, includes: using multiple sets of fixed remote spotlights arranged vertically on both sides of the gate to detect the ship's speed, position and draft at the gate.

[0012] Secondly, a waterway lock passage and navigation monitoring system is provided, comprising: multiple sets of remote spotlights arranged along the lock entry direction; a controller connected to the remote spotlights, the controller being used to acquire the ship's speed and position information based on the multiple sets of remote spotlights; the controller is also used to accurately arrange the ship's entry into the lock based on the ship's position information, generating entry arrangement information; calculating the ship's entry speed and entry route based on the entry arrangement information; determining in real time whether the ship's speed information meets the entry speed and whether the route meets the entry route, and controlling the ship to enter the lock according to the calculated entry speed and route.

[0013] In some embodiments, the remote spotlight includes a fixed remote spotlight, which includes a fixed transmitter and a fixed receiver, and the fixed transmitter and the fixed receiver are respectively disposed on both sides of the waterway.

[0014] In some embodiments, the remote spotlights further include mobile remote spotlights, with multiple mobile remote spotlights arranged along the gate entry direction between the fixed transmitting light and the fixed receiving light, such that at least two channels are formed between the fixed transmitting light and the fixed receiving light in each group of fixed remote spotlights; the mobile remote spotlights are signal-connected to the controller, and the controller is used to control the mobile remote spotlights to move automatically at any position between the two sides of the waterway; each mobile remote spotlight has a transmitting surface and a receiving surface, with the transmitting surface facing the fixed receiving light and the receiving surface facing the fixed transmitting light.

[0015] In some embodiments, the remote spotlight includes a mobile remote spotlight, and the controller is further configured to control at least one of the mobile remote spotlights to move between two adjacent vessels along the gate entry direction and follow the movement of the two vessels. The emitted light of the mobile remote spotlight is parallel to the direction of movement of the vessels. The mobile remote spotlight integrates a visibility sensing module, which is configured to generate different colored indicator lights according to different levels of visibility.

[0016] The beneficial effects of the technical solution provided by this invention include:

[0017] This invention provides a waterway lock passage and navigation monitoring method and system. Because the light from the remote spotlight has strong penetrating power, it can penetrate the water mist to monitor ships in foggy weather, and obtain the ship's speed and position information in a timely manner. Then, the ship's entry into the lock can be scheduled based on the ship's speed and position information. Therefore, instead of using a camera for monitoring, the remote spotlight can obtain the ship's position and speed more accurately, and complete the ship scheduling accurately and in a timely manner.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides a waterway lock passage and navigation monitoring method, which can solve the problem in related technologies where water mist severely affects the clarity of images captured by cameras, thus making it impossible to accurately and timely complete the scheduling of ships.

[0028] See Figure 1 and Figure 2 As shown, a waterway navigation monitoring method according to an embodiment of the present invention may include the following steps:

[0029] S1: Obtain the speed and position information of vessel 3 based on multiple sets of long-range spotlights. That is, multiple sets of long-range spotlights, such as searchlights or lasers, can be placed on the banks 5 on both sides of the waterway before vessel 3 enters the lock gate. Long-range spotlights can also be placed at the lock gate. Multiple sets of long-range spotlights can be arranged along the extension direction of the waterway (i.e., the direction of entering the lock). The speed information and position on the water surface of vessel 3 can be obtained through the long-range spotlights.

[0030] S2: Based on the position information of vessel 3, the precise entry and blocking of vessel 3 is performed, generating entry and blocking information. That is to say, there may be one or more vessels 3 on both sides of the waterway in front of the lock. Before vessel 3 enters the lock, the entry and blocking of each vessel 3 can be performed based on the position information of each vessel 3, that is, which vessel enters the lock first and which vessel enters the lock later, thereby forming entry and blocking information for all vessels 3.

[0031] S3: Calculate the entry speed and navigation route of vessel 3 based on the entry scheduling information. In this embodiment, the controller can accurately schedule the entry of vessel 3 based on the position information of vessel 3 on the waterway fed back by multiple sets of remote spotlights, and calculate the entry speed and navigation route based on the entry scheduling information, so that vessel 3 on the waterway enters the lock according to the entry speed and navigation route. The entry speed can be variable; that is, the entry speed can be different at different positions on the entry navigation route, or it can be the same.

[0032] S4: Real-time determination of whether the speed information of vessel 3 meets the lock-entry speed and whether the navigation route meets the lock-entry navigation route, and control vessel 3 to enter the lock according to the calculated lock-entry speed and lock-entry navigation route. That is, in this embodiment, the lock-entry speed and lock-entry navigation route can be used as a benchmark. When it is found that the real-time speed information and navigation route of vessel 3 deviate from the benchmark lock-entry speed and lock-entry navigation route, the speed or navigation route of vessel 3 can be adjusted to make its speed and navigation route conform to the lock-entry speed and lock-entry navigation route. Among them, step S1 calculates the speed and position of each vessel 3 before entering the lock; steps S2-S3 calculate the lock-entry speed and lock-entry navigation route of each vessel 3 during the lock-entry process; step S4 controls each vessel 3 to enter the lock according to the lock-entry speed and lock-entry navigation route.

[0033] In this embodiment, because multiple sets of long-range spotlights are deployed on the waterway, the light from the long-range spotlights has strong penetrating power during the monitoring of vessel 3. It can penetrate dense fog and monitor vessel 3 through water fog, timely and accurately obtaining the speed and position information of vessel 3. Then, the vessel 3 can be scheduled to enter the lock using the speed and position information of vessel 3. Therefore, instead of using a camera for monitoring, the long-range spotlights can obtain the position and speed of vessel 3 more accurately, and complete the scheduling of vessel 3 accurately and timely. Moreover, it is not affected by the image clarity of the camera due to water fog, which can solve the problem of low monitoring accuracy of vessel 3 when passing through the lock in water fog or when the lock releases water to form a large amount of water fog (or dense fog).

[0034] Meanwhile, the remote spotlight in this embodiment can also be used in conjunction with existing monitoring systems. Existing monitoring systems are used in situations with high visibility (such as clear weather), while the remote spotlight in this embodiment is used in situations with low visibility (such as dense fog or water mist). The remote spotlight can be turned off in situations with high visibility.

[0035] Furthermore, in this embodiment, multiple sets of remote spotlights are arranged at intervals, and the positions of each set of remote spotlights and the distance between two adjacent sets of remote spotlights are known. Therefore, when the ship 3 reaches the remote spotlight, the ship 3 will be detected by the remote spotlight, and the position of the ship 3 can be determined based on the position of the remote spotlight. By using multiple sets of remote spotlights, it can be known when the ship 3 moves to which remote spotlight, and the speed information of the ship 3 can be calculated based on the time and distance.

[0036] See Figure 2 As shown, in some embodiments, the remote spotlights may include fixed remote spotlights 1. Each group of fixed remote spotlights 1 may include a fixed transmitter 11 and a fixed receiver 12. The fixed transmitter 11 and the fixed receiver 12 are respectively arranged on both sides of the waterway. The fixed transmitter 11 can emit light, and the fixed receiver 12 can receive light. The light emitted by a corresponding fixed transmitter 11 can be received by the corresponding fixed receiver 12 and will not be emitted to other fixed receivers 12. The process of obtaining the speed and position information of the vessel 3 based on multiple groups of remote spotlights may include: determining the position information of the vessel 3 based on whether each fixed receiver 12 receives light emitted by the fixed transmitter 11 in the same group; and determining the speed information of the vessel 3 based on the position information and time of the vessel 3 at different times.

[0037] In this embodiment, since the fixed transmitting light 11 and the fixed receiving light 12 are distributed on both sides of the waterway, a channel 4 is formed between the fixed transmitting light 11 and the fixed receiving light 12. Before entering the lock, the ship 3 will enter the channel 4. When no ship 3 enters the position corresponding to the fixed transmitting light 11 and the fixed receiving light 12, the fixed receiving light 12 will receive the light emitted by the corresponding fixed transmitting light 11 without being blocked. When a ship 3 enters the position corresponding to the fixed transmitting light 11 and the fixed receiving light 12, the light emitted by the fixed transmitting light 11 will be blocked by the ship 3, so that the fixed receiving light 12 cannot receive the light emitted by the fixed transmitting light 11. Thus, it can be known which set of fixed remote spotlights 1 the ship 3 has moved to. Assuming three consecutive sets of fixed long-range spotlights 1 receive no light, the position of vessel 3 is determined by the middle set of these three sets of spotlights. Similarly, if two consecutive sets of fixed long-range spotlights 1 receive no light, the position of vessel 3 is determined by the middle set of these two sets of spotlights. Furthermore, the fixed long-range spotlights 1 can be spaced closer together for more accurate position determination. Since adjacent vessels 3 along the lock-entry direction are not very close, when both adjacent vessels 3 partially block the fixed long-range spotlights 1, there will be at least one set of spotlights 1 that can receive light between the two sets of spotlights that are not receiving light. This allows for the precise determination of the positions of the two adjacent vessels 3 along the lock-entry direction.

[0038] Since the ship 3 is moving, it will block the fixed long-range spotlights 1 at different times. Based on the time it takes for the ship 3 to move from one fixed long-range spotlight 1 to another, and the distance between the two fixed long-range spotlights 1, the speed information of the ship 3 can be calculated.

[0039] Of course, in other embodiments, each set of fixed long-range spotlights 1 can also be set on one side of the waterway, and each set of fixed long-range spotlights 1 can determine the presence of a ship 3 by the distance the emitted light reaches.

[0040] Furthermore, each fixed transmitting lamp 11 and fixed receiving lamp 12 can be labeled, which allows for quick location of the corresponding position of each fixed transmitting lamp 11 and fixed receiving lamp 12.

[0041] See Figure 2As shown, in some optional embodiments, the remote spotlights may further include mobile remote spotlights. The acquisition of the speed and position information of the vessel 3 based on multiple sets of remote spotlights may further include: acquiring the speed and position information of two adjacent vessels 3 entering the lock side-by-side, based on multiple sets of fixed remote spotlights 1 combined with multiple mobile remote spotlights 2 located between two adjacent vessels 3 entering the lock side-by-side. That is, in this embodiment, in addition to multiple sets of fixed remote spotlights 1, multiple mobile remote spotlights 2 are also provided. The mobile remote spotlights 2 can automatically travel on the waterway and move to different positions, and can also be retracted when not in use to improve the service life of the mobile remote spotlights 2. Since the fixed long-range spotlights 1 on both sides of the waterway may not be able to detect the situation when multiple vessels 3 enter the lock side by side, this embodiment can separately set up multiple movable long-range spotlights 2 to adapt to the situation when multiple vessels 3 enter the lock side by side. The multiple movable long-range spotlights 2 can be moved between two adjacent vessels 3 entering the lock side by side, so that the movable long-range spotlights 2 and the fixed long-range spotlights 1 can form at least two channels 4 together. The movable long-range spotlights 2 and the fixed long-range spotlights 1 can monitor the vessels 3 in each channel 4 together, thereby realizing the monitoring of multiple vessels 3 entering the lock side by side.

[0042] That is, multiple mobile long-range spotlights 2 can be arranged in a row along the gate entry direction, and one row of mobile long-range spotlights 2 is located between the fixed transmitter 11 and the fixed receiver 12 of the fixed long-range spotlight 1, thereby forming two channels 4 between the fixed transmitter 11 and the fixed receiver 12; of course, multiple mobile long-range spotlights 2 can also be arranged in two alternate rows along the gate entry direction, and the two rows of mobile long-range spotlights 2 are located between the fixed transmitter 11 and the fixed receiver 12 of the fixed long-range spotlight 1, thereby forming three channels 4 between the fixed transmitter 11 and the fixed receiver 12, and so on, four or more channels 4 can be formed, which can be set according to the actual situation.

[0043] In this case, each side of the waterway can be equipped with fixed transmitting lights 11, fixed receiving lights 12, or a combination of fixed transmitting lights 11 and fixed receiving lights 12. In other words, the lights on each side can be arranged arbitrarily, as long as it is ensured that one side of each waterway 4 can transmit light and the other side can receive light.

[0044] Furthermore, the step of obtaining the speed and position information of two adjacent vessels 3 entering the lock side-by-side based on multiple sets of fixed long-range spotlights 1 combined with multiple mobile long-range spotlights 2 located between two adjacent vessels 3 entering the lock side-by-side may include: using the mobile long-range spotlights 2 to emit or receive light, and receiving or emitting light through the corresponding fixed long-range spotlights 1; determining the speed and position information of the two adjacent vessels 3 entering the lock side-by-side based on the light reception status of the mobile long-range spotlights 2 or the fixed long-range spotlights 1. Preferably, each mobile long-range spotlight 2 can integrate an emitting light and a receiving light, so that the mobile long-range spotlight 2 has at least one emitting surface 21 and a receiving surface 22, wherein the emitting surface 21 can emit light and the receiving surface 22 can receive light. When a row of mobile long-range spotlights 2 is set up with fixed emitting lights 11 and fixed receiving lights 12, each mobile long-range spotlight 2 can be set up corresponding to one of the fixed long-range spotlights 1, so that after the emitting surface 21 of the mobile long-range spotlight 2 emits light into one of the channels 4, the corresponding fixed receiving light 12 can receive the light, and after the corresponding fixed emitting light 11 emits light into another channel 4, the receiving surface 22 of the mobile long-range spotlight 2 can receive the light. Of course, when a ship 3 passes by, the light cannot be received because it is blocked.

[0045] In this embodiment, the mobile long-range spotlight 2 can be used in conjunction with the fixed long-range spotlight 1, so that the position and speed of the ships 3 can be monitored when they are sailing side by side. This makes the monitoring of the speed and position of the ships 3 more effective in dense fog. The mobile long-range spotlight 2 and the fixed long-range spotlight 1 can feed back signals to the controller to obtain the position and speed of each ship 3 sailing side by side.

[0046] Of course, in other embodiments, the mobile remote spotlights 2 can all be configured to emit light and the fixed remote spotlights 1 can all receive light, or the mobile remote spotlights 2 can all receive light and the fixed remote spotlights 1 can all emit light. This mode can also achieve the monitoring of multiple waterways 4 and vessels 3.

[0047] See Figure 2As shown, in some embodiments, the waterway lock passage and navigation monitoring method may further include: controlling a mobile long-range spotlight 2 to move between two adjacent vessels 3 along the lock entry direction. That is, along the lock entry direction, there may be multiple vessels 3 traveling along the route, with the vessels 3 spaced apart. Since the mobile long-range spotlight 2 can move automatically on the waterway, it can be controlled to move between two adjacent vessels 3 along the lock entry direction; and navigation is performed using the mobile long-range spotlight 2 positioned between two adjacent vessels 3 along the lock entry direction. In this embodiment, the light from the mobile long-range spotlight 2 has strong penetrating power, can penetrate dense fog, and can provide illumination over a long distance at night. By controlling the mobile long-range spotlight 2 to move between two adjacent vessels 3 along the lock entry direction, the emitted light of the mobile long-range spotlight 2 can be parallel to the direction of movement of the vessels 3, illuminating the preceding vessel 3 for the following vessel 3, thereby knowing the position of the preceding vessel 3, so that the two adjacent vessels 3 can maintain a safe distance. Furthermore, the mobile long-range spotlight 2 can also be used as a navigator to guide the vessel 3 in dense fog. The mobile long-range spotlight 2 can guide the vessel 3 along the correct navigation route. Because the mobile long-range spotlight 2 can emit highly penetrating light and can move automatically on the water, operators can control it to navigate the vessel 3, thus enhancing safety during lock passage.

[0048] Furthermore, the mobile long-range spotlight 2 can also be integrated with a visibility sensing module, which can generate white, yellow, red and other colored lights according to different levels of visibility when visibility is low in foggy weather, so as to provide the captain with clear and long-distance navigation route guidance.

[0049] In some embodiments, the real-time determination of whether the speed information of vessel 3 meets the entry speed and whether the navigation route meets the entry route, and the control of vessel 3 to enter the lock according to the calculated entry speed and navigation route, may include: real-time determination of whether the speed information of vessel 3 meets the entry speed and whether the navigation route meets the entry route; if so, allowing vessel 3 to enter the lock; otherwise, issuing an alarm and controlling vessel 3 to enter the lock according to the calculated entry speed and navigation route. This ensures that all vessels 3 can enter the lock according to the calculated safe entry speed and navigation route. In actual operation, vessels 3 are generally required to pass through the lock chamber in a single-pass manner. When there are multiple vessels 3 in a lock chamber, multiple parallel channels 4 can be set up for entry.

[0050] Preferred, see Figure 2 and Figure 3As shown, the remote spotlights may also include fixed remote spotlights 1 arranged vertically on both sides of the gate. The real-time determination of whether the ship 3's speed information matches the gate entry speed and whether its navigation route matches the gate entry route, and the control of the ship 3 to enter the gate according to the calculated entry speed and navigation route, may include: using multiple sets of fixed remote spotlights 1 arranged vertically on both sides of the gate to detect the ship 3's speed, position, and draft at the gate. That is, in this embodiment, multiple sets of fixed remote spotlights 1 (such as searchlights) can also be installed on the passageway walls 6 on both sides of the gate. These multiple sets of fixed remote spotlights 1 can be arranged vertically, meaning each set of fixed remote spotlights 1 has a different height. Some fixed remote spotlights 1 can be located on the water surface, and some can be located below the water surface. Of course, all fixed remote spotlights 1 can also be arranged below the water surface. Each set of fixed remote spotlights 1 may include fixed transmitting lights 11 and fixed receiving lights 12 distributed on both sides of the ship 3. Since each set of fixed long-range spotlights 1 is at a different depth in the water, the draft of the vessel 3 can be determined by whether the fixed long-range spotlights 1 at different depths receive light. For example, if the top three sets of fixed long-range spotlights 1 do not receive light, but the bottom three sets do, it indicates that the bottom of the vessel 3 is located between the third and fourth sets of fixed long-range spotlights 1. Furthermore, multiple sets of fixed long-range spotlights 1 are also arranged on the passageway walls 6 on both sides of the lock along the entry direction. These multiple sets of fixed long-range spotlights 1 arranged along the entry direction can monitor the position and speed of the vessel 3.

[0051] Of course, multiple vertically arranged fixed long-range spotlights 1 can also be installed on the embankment 5 before entering the lock gate, so that the draft of the ship 3 can be detected before entering the lock gate.

[0052] Furthermore, when vessel 3 passes through the lock, the ascending or descending speed of vessel 3 can be detected by monitoring the operation of multiple sets of vertically and horizontally arranged fixed long-range spotlights 1 installed on the passageway walls 6 on both sides of the lock gate, ensuring the safe passage of vessel 3. For example, when vessel 3 ascends from downstream to upstream, the ascending speed of vessel 3 can be detected to ensure its safe passage through the lock.

[0053] Preferably, the fixed long-range spotlight 1 and the mobile long-range spotlight 2 can also be integrated with warning lights. The warning lights can display red or yellow and inform the captain how many vessels 3 are ahead by the flashing frequency of the warning lights. Furthermore, the mobile long-range spotlight 2 can also be integrated with a display screen, through which the captain can obtain the water temperature information of the water area locked by the vessel 3 and the navigation information of the vessel 3 ahead.

[0054] In actual operation, the fixed long-range spotlight 1 can be set up on both sides of the waterway for a long time, while the mobile long-range spotlight 2 can be moved and retrieved. Both the fixed long-range spotlight 1 and the mobile long-range spotlight 2 can be used only in foggy weather.

[0055] See Figure 2 and Figure 3 As shown in the figure, a waterway lock passage and navigation monitoring system provided by an embodiment of the present invention may include: multiple sets of remote spotlights, the multiple sets of remote spotlights being arranged along the lock entry direction; a controller, the controller being signal-connected to the remote spotlights, and the controller being used to acquire the speed information and position information of vessel 3 based on the multiple sets of remote spotlights; the controller is also used to accurately arrange the lock entry of vessel 3 based on the position information of vessel 3, generating lock entry arrangement information; calculate the lock entry speed and lock entry navigation route of vessel 3 based on the lock entry arrangement information; determine in real time whether the speed information of vessel 3 meets the lock entry speed and whether the navigation route meets the lock entry navigation route, and control vessel 3 to enter the lock according to the calculated lock entry speed and lock entry navigation route.

[0056] Furthermore, the long-range spotlights include fixed long-range spotlights 1. Multiple sets of the fixed long-range spotlights 1 can be arranged on both sides of the waterway in front of the gate along the gate entry direction. Each set of the fixed long-range spotlights 1 includes a fixed transmitting light 11 and a fixed receiving light 12. The fixed transmitting light 11 and the fixed receiving light 12 are distributed on both sides of the waterway, that is, the fixed transmitting light 11 and the fixed receiving light 12 are distributed on different sides of the waterway. One can emit light and the other can receive light. The fixed transmitting light 11 and the fixed receiving light 12 in each set of fixed long-range spotlights 1 can be used together to detect the position of the vessel 3.

[0057] Furthermore, in some embodiments, the remote spotlight may also include a mobile remote spotlight 2, with multiple mobile remote spotlights 2 arranged along the gate entry direction between the fixed transmitting light 11 and the fixed receiving light 12 of each group of fixed remote spotlights 1, such that at least two channels 4 are formed between the fixed transmitting light 11 and the fixed receiving light 12 of each group of fixed remote spotlights 1; the mobile remote spotlight 2 is signal-connected to the controller, and the controller is used to control the mobile remote spotlight 2 to move automatically at any position between the two sides of the waterway; each mobile remote spotlight 2 has a transmitting surface 21 and a receiving surface 22, with the transmitting surface 21 facing the fixed receiving light 12 and the receiving surface 22 facing the fixed transmitting light 11. In this embodiment, a mobile long-range spotlight 2 can be used to emit or receive light, and a corresponding fixed long-range spotlight 1 can be used to receive or emit light. Then, based on the light reception status of the mobile long-range spotlight 2 or the fixed long-range spotlight 1, the speed and position information of two adjacent vessels 3 entering the lock can be determined and arranged.

[0058] In some optional embodiments, the controller is also used to control at least one of the mobile remote spotlights 2 to move between two adjacent vessels 3 along the gate entry direction and follow the movement of the two vessels 3, wherein the emitted light of the mobile remote spotlight 2 is parallel to the movement direction of the vessels 3; the mobile remote spotlight 2 integrates a visibility sensing module, which is used to generate different colored warning lights according to different levels of visibility.

[0059] Furthermore, the mobile long-range spotlight 2 can also be integrated with a visibility sensing module, which can generate white, yellow, red and other colored lights according to different levels of visibility when visibility is low in foggy weather, so as to provide the captain with clear and long-distance navigation route guidance.

[0060] In some embodiments, the long-range spotlights may further include multiple sets of fixed long-range spotlights 1 installed on the passageway walls 6 on both sides of the gate. These multiple sets of fixed long-range spotlights 1 can be arranged vertically, meaning each set has a different height. Some fixed long-range spotlights 1 may be above the water surface, while others may be below. Alternatively, all fixed long-range spotlights 1 can be arranged below the water surface. Each set of fixed long-range spotlights 1 may include fixed transmitting lights 11 and fixed receiving lights 12 distributed on both sides of the vessel 3. Since each set of fixed long-range spotlights 1 is at a different depth in the water, the draft of the vessel 3 can be determined by whether the fixed long-range spotlights 1 at different depths receive light. For example, if the top three sets of fixed long-range spotlights 1 do not receive light, while the bottom three sets do, it indicates that the bottom of the vessel 3 is located between the third and fourth sets of fixed long-range spotlights 1. Furthermore, multiple sets of fixed long-range spotlights 1 are arranged on the passageway walls 6 on both sides of the gate along the direction of entry. These multiple sets of fixed long-range spotlights 1 along the direction of entry can monitor the position and speed of the ship 3.

[0061] When vessel 3 passes through the lock, the ascending or descending speed of vessel 3 can be detected by monitoring the operation of multiple sets of vertically and horizontally arranged fixed long-range spotlights 1 installed on the passageway walls 6 on both sides of the lock gate, ensuring the safe passage of vessel 3. For example, when vessel 3 ascends from downstream to upstream, the ascending speed of vessel 3 can be detected to ensure the safe passage of vessel 3.

[0062] Preferably, the fixed long-range spotlight 1 and the mobile long-range spotlight 2 can also be integrated with warning lights. The warning lights can display red or yellow and inform the captain how many vessels 3 are ahead by the flashing frequency of the warning lights. Furthermore, the mobile long-range spotlight 2 can also be integrated with a display screen, through which the captain can obtain the water temperature information of the water area locked by the vessel 3 and the navigation information of the vessel 3 ahead.
