Description

Technical Field

[0001] The utility model belongs to the technical field of navigation dispatching, and in particular relates to a ship sensing device based on infrared laser. Background Art

[0002] The ship lift navigation dispatch management system (navigation dispatch system) is an independent navigation dispatch business information management system. The entire process of a ship passing through the ship lift needs to record a lot of time. By combining this time with big data analysis such as basic ship information and cargo information, the ship passing process is optimized and the ship passing efficiency is improved.

[0003] Due to network security requirements, the navigation dispatching system cannot access dynamic data such as the ship lift control system. At the same time, some time collection points are in a closed environment with weak wireless signals, which is not conducive to data collection through the wireless platform. Therefore, all key node times are manually recorded by the dispatcher by clicking a button. There is a possibility of human omissions, which may lead to time errors and is not conducive to subsequent data and process analysis and optimization. Utility Model Content

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0024] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0025] Due to network security requirements, the navigation dispatching system cannot access dynamic data such as the ship lift control system. At the same time, some time collection points are in a closed environment with weak wireless signals, which is not conducive to data collection through the wireless platform. Therefore, all key node times are manually recorded by the dispatcher by clicking a button. There is a possibility of human omissions, which may lead to time errors and is not conducive to subsequent data and process analysis and optimization.

[0026] In order to solve the above technical problems, the following embodiments of the present invention are proposed, which are a ship sensing device based on infrared laser.

[0027] Reference Figure 1 ,like Figure 1 The figure shows the structure of a device for accurately sensing ships using infrared laser dynamics, according to an embodiment of the present application. The device is installed in a waterway where a ship 1 passes through, and is used to accurately sense the ship 1 even in environments with weak wireless signals. Specifically, it comprises a vertical guide rail 2, a pan / tilt platform 3, an infrared laser beaming device 4, a water level data monitoring device 9, and a control center 8. The device senses the ship 1 by beaming from two infrared laser beaming devices 4 on either side of the waterway.

[0028] Among them, the vertical guide rail 2 is installed on both sides of the waterway, and the pan-tilt head 3 is installed on the vertical guide rail 2 as a carrier for the infrared laser shooting device 4. The pan-tilt head 3 can slide arbitrarily on the vertical guide rail 2, and the infrared laser shooting device 4 is installed on the pan-tilt head 3. The infrared laser shooting device 4 can adjust its horizontal distance from the ground through the movement of the pan-tilt head 3 on the vertical guide rail 2.

[0029] Vertical guide rails 2 are fixed symmetrically on either side of the aqueduct and auxiliary lock chamber, providing a range for the pan / tilt platform 3 to move upward or downward, and restricting its movement within a predetermined trajectory. The pan / tilt platform 3 is used to mount and secure the infrared laser beam device 4, controlling its movement to achieve a desired position.

[0030] In an embodiment of the present application, the water level data monitoring device 9 is arranged beside the waterway, and is used to monitor the water level data of the waterway in real time when the ship 1 passes through the waterway.

[0031] In an embodiment of the present application, the control center 8 can be implemented by a computer device, a laptop computer, etc., which is used to receive the perception signal of the infrared laser shooting device 4 and the water level data obtained by the water level data monitoring device 9, and to control the movement of the pan-tilt head 3 and issue scheduling instructions to the ship 1 through the control center 8, thereby avoiding scheduling omissions caused by weak wireless signals in a closed environment.

[0032] In an embodiment of the present application, the infrared laser dynamic precise sensing ship device further includes a driver, which is in communication with the control center 8 and drives the pan-tilt platform 3 to rise and fall according to the lifting and lowering instructions sent by the control center 8.

[0033] In the embodiment of the present application, the vertical guide rails 2 are installed on both sides of the aqueduct and the auxiliary lock chamber of the ship lift navigation structure.

[0034] In the embodiment of the present application, a scale 7 is also provided on the vertical guide rail 2, and an image acquisition device 6 is provided on the pan-tilt head 3 for obtaining the scale of the position of the pan-tilt head 3. The image acquisition device 6 is communicated with the control center 8. The image acquisition device 6 obtains the specific scale of the position of the pan-tilt head 3 and transmits it to the control center 8. The control center 8 uses this to determine whether the position of the pan-tilt head 3 is accurate.

[0035] In this embodiment of the present application, the vessel 1 is also equipped with its own control center, attitude sensor 101, and water level sensor 102. The attitude sensor 101 and water level sensor 102 are respectively connected to the vessel's control center, which is located in the cockpit of the vessel 1. The attitude sensor 101 and water level sensor 102 monitor the draft and attitude of the vessel 1 in real time, ensuring that the cockpit can monitor the vessel's status.

[0036] In this embodiment of the present application, the pan / tilt head 3 is further provided with a video capture device 5, which is in communication with a control center 8. The video capture device 5 is a spherical camera. Upon receiving a signal indicating that the vessel 1 is being detected, the control center 8 issues a start command to the video capture device 5. The video capture device 5 then captures a video of the vessel 1 passing through the waterway and transmits the video to the control center 8 for storage and filing.

[0037] The infrared laser shooting device 4 is installed in key locations such as the aqueduct of the ship lift navigation structure and the auxiliary lock chamber according to the actual scene requirements. It completes the perception of the ship 1 by periodically sending signals. When the ship 1 passes through the process of sensing the infrared laser shooting device 4, the infrared laser shooting device 4 generates a series of continuous signals and transmits the generated signals to the control center 8 through the optical fiber local area network.

[0038] The control center 8 receives and processes the data from the infrared laser shooting device 4, determines whether the signal is generated by the ship 1 based on the perception data, and finally infers the time when the ship 1 passes the infrared laser shooting device 4, and records it in the database as the specific key time of the ship passing the machine.

[0039] The water level data is compared with the reference water level, and a displacement adjustment signal is sent to the only driver according to the difference. The displacement driver completes the displacement adjustment of the pan / tilt platform 3 according to the displacement signal.

[0040] Embodiments of the present application.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
