During the berthing process, the meteorological, hydrological and other environmental information is not accurate enough, and the restrictiveness of the port waters poses a great challenge to the maneuverability of the ship and the technical ability of the pilot. It is usually accompanied by a laser ranging auxiliary system. The laser ranging auxiliary system generally includes two parallel laser rangefinders, which detect the offshore distance of two points on the ship, calculate the speed according to the change of the offshore distance per unit time, and calculate the angle between the ship and the dock according to the offshore distance. The entire process of the ship berthing at the dock is presented in real time on the software platform, which is convenient for the pilotage, maritime affairs, and dock parties to guide the ship's berthing operations through the terminal, and prevent the dock facilities from being damaged and equipment accidents due to excessive speed or excessive angle when the ship is berthing.

[0003] After berthing, the ship needs to be fixed with a cable, one end of which is fixed on the ship deck and the other end is put on the dock pile to ensure the safe transportation of goods. Although the laser ranging auxiliary system can continue to monitor the ship's distance from the shore and the angle of the ship after berthing, the lack of monitoring of the cable poses certain safety hazards. At present, the monitoring of the cable generally relies on manual inspection, which has problems such as lack of real-time performance, blind inspection areas, and low accuracy. In addition, the manpower investment is large, especially in bad weather, and the inspection frequency needs to be increased, so there is still room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] Embodiment 1: Figure 1As shown, a ship mooring monitoring system includes a laser ranging module 1, a control processing module 2, a display module 3, an alarm module 4 and a camera module 5 arranged at a dock end. The laser ranging module 1, the display module 3, the alarm module 4 and the camera module 5 are respectively connected to the control processing module 2. The laser ranging module 1 is used to collect distance information between the ship and the dock, and send the collected distance information to the control processing module 2, and the control processing module 2 then uploads the distance information to the display module 3. The camera module 5 includes multiple cameras 51 and a network switch 52. The camera 51 is used to collect image information of the cable between the ship and the dock, and send the collected image information to the network switch 52. The network switch 52 sends the image information to the control processing module 2, and the control processing module 2 then uploads the image information to the display module 3.

[0024] In this embodiment, the laser distance measuring module 1 includes two parallel laser distance measuring devices 11, one laser distance measuring device 11 is used to monitor the distance between the bow of the ship and the dock, and the other laser distance measuring device 11 is used to monitor the distance between the stern of the ship and the dock.

[0025] In this embodiment, the display module 3 includes a display screen 31 and a storage hard disk 32. The display screen 31 is used to present images, and the storage hard disk 32 is used to store videos for later playback, analysis or evidence collection.

[0026] In this embodiment, the control processing module 2 is connected to the mobile intelligent terminal 6 via wireless communication. The mobile intelligent terminal 6 is such as a PC or a smart phone. Taking a smart phone as an example, the staff can view videos and receive alarm information through WeChat public accounts, mini-programs, etc., which has good flexibility and is conducive to improving work efficiency. This method is also a relatively mature technical means on the market.

[0027] When actually setting the installation position of camera 51, since there are many buildings and machinery near the wharf berth and their distribution is wide, the conditions for installing camera 51 are met. Camera 51 can be installed at multiple angles selected in combination with the buildings and machinery near the wharf berth, so as to collect image information of the cable from different perspectives from multiple angles and reduce inspection blind spots. Among them, camera 51 is fixedly installed and does not need to be moved or disassembled later.

[0028] During the actual monitoring process, the camera 51 first collects the image information between the ship and the dock, and then extracts the image information of the cable through the image segmentation algorithm. The staff observes the image information of the cable and confirms the real-time status of the cable based on experience. The real-time status of the cable can also be obtained through big data comparison and judgment. Compared with the staff judging the cable status based on experience, it has higher accuracy and can achieve 7*24 hours real-time monitoring, analysis and judgment. If the cable is loose, broken or other abnormalities occur, the alarm module 4 will sound an alarm to remind the staff to check and repair.

[0029] Conventional manual inspections can only detect cables within a limited time period, cannot cover a large production time window, have poor real-time performance, and are difficult to detect and handle early. After adopting this technical solution, the image information of the cables between the ship and the dock is collected by the camera 51, and then sent to the control processing module 2 through the network switch 52, and finally presented to the display module 3 for the staff to view, so as to quickly obtain the real-time status information of multiple cables, that is, all cables can be monitored in real time, with strong real-time performance, and can also reduce labor costs.

[0030] It should be noted that the image segmentation algorithm extracts the image information of the target and then uses big data comparison to determine whether the target has defects, which is already very mature. Please refer to the transmission line loose strand defect detection method based on visible light images disclosed in Patent No. ZL2017104364316.

[0031] Embodiment 2: Figures 1 to 3 As shown, the rest of the parts are the same as those in the first embodiment, except that the camera module 5 further includes a mounting frame 53 arranged at the end of the dock, and the camera 51 is arranged on the mounting frame 53 .

[0032] In this embodiment, a slide rail 54 extending in the horizontal direction is provided on the mounting frame 53, and a plurality of sliders 55 are provided on the slide rail 54. The plurality of sliders 55 correspond one to one with the plurality of cameras 51, and the cameras 51 are fixedly arranged on the corresponding sliders 55. The design of this structure is convenient for the staff to quickly adjust the position of the camera 51 according to the position, length and distance of the moored ship, so as to collect the image information between the ship and the dock clearly and completely, and then facilitate the back end to make an accurate judgment on the real-time status of the cable, and has good flexibility.

[0033] In this embodiment, the mounting frame 53 is also provided with a rack 57 and a rain shield 58 parallel to the slide rail 54. The rain shield 58, the rack 57 and the slide rail 54 are arranged from top to bottom. The slider 55 is provided with a driving motor 56. A gear 59 is fixedly provided on the driving shaft of the driving motor 56. The gear 59 is meshed with the rack 57. The staff only needs to control the rotation of the driving motor 56 to adjust the position of the slider 55 and the camera 51. The operation is relatively simple and convenient. The setting of the rain shield 58 protects the gear 59 and the rack 57 to a certain extent, so as to extend the service life and reduce the frequency of maintenance and repair.

[0034] In this embodiment, the alarm module 4 includes a first alarm unit 41 disposed next to the display module 3, and the first alarm unit 41 includes a first warning light 411 and a first buzzer 412. The conventional display module 3 is generally located in the monitoring room of the dock. When an abnormal state is detected, an audible and visual alarm is issued through the first warning light 411 and the first buzzer 412 to remind the staff in the monitoring room to coordinate personnel to handle it as soon as possible. At the same time, the display screen 31 will also display the abnormal cable name, cable number, location, alarm type, alarm time, alarm video, and handling status.

[0035] Embodiment 3: Figure 1 As shown, the rest of the parts are the same as those in the second embodiment, except that the alarm module 4 further includes a plurality of second alarm units 42, and the plurality of second alarm units 42 correspond to the plurality of cameras 51 one by one, and the second alarm units 42 are arranged beside the corresponding cameras 51, and the second alarm units 42 include a second warning light 421 and a second buzzer 422. The second alarm unit 42 is arranged beside the camera 51, and when an abnormal state is detected, an audible and visual alarm is issued through the second warning light 421 and the second buzzer 422 to remind the staff on site to pay attention to safety, and to facilitate the staff to confirm the abnormal location and deal with the abnormal situation as soon as possible.

[0036] After adopting this technical solution, management personnel will conduct remote inspections instead of manual on-site inspections, which is expected to reduce labor costs by more than 300,000 yuan each year and achieve 7*24 hours real-time and comprehensive monitoring, improve cable monitoring efficiency, reduce safety management risks, and help promote the unmanned and intelligent construction of bulk terminals, helping to promote the company's high-quality development.

[0037] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
