Description

Construction method and system of ship deck cable database
Technical Field
The invention relates to the technical field of crossing between the field of ships and the field of computers, in particular to a method and a system for constructing a ship deck cable database.
Background
Monitoring of unsafe behavior of a crewman deck cable is a crucial step in a monitoring system of the behavior of the crewman, and along with the wide application of video monitoring technology in the field of ships, the unsafe behavior of the operation of the crewman cable is gradually changed from monitoring dominated by personnel and experience to video intelligent monitoring, and the video intelligent monitoring is also gradually accepted by crewman and on-road monitoring personnel in the operation of the ships.
However, video monitoring of unsafe behavior of crews in the field of ships is currently not widely studied and applied, and has the following three main difficulties:
1. object tracking management is difficult. The work of the crew is an international work, and usually ocean vessels are required to navigate in the global scope, so that the research is relatively difficult, and the crew can be conveniently tracked and managed in fixed places such as mines, railway stations and the like.
2. Real-time contact is difficult. The signals on the ocean vessel cannot be kept good like on land, so that the signals cannot be timely connected and timely communication cannot be achieved like on shore.
3. Because the ship has the characteristics of rolling, pitching and the like which are not possessed on land, the characteristics of unstable video images and the like can be met in the video acquisition process, and the method for manufacturing the land data set cannot be fully applied.
Thanks to the rapid development of video monitoring technology, intelligent, convenient and efficient identification can be realized in the land field. However, due to the special working environment and the special working property of the ship, the system cannot be directly applied to a monitoring system on the road, and therefore, the independent research and development of the ship and the establishment of a set of monitoring and early warning platform for checking the unsafe behaviors and the states of the crew are additionally important. In the process of establishing video monitoring, the only step requiring more human participation is to establish a complete unsafe behavior data set, and a set of data set integrating all unsafe behaviors must be completed to accurately identify and timely remind in the future identification process. At present, the data set is made by collecting a series of unsafe behaviors when a shipman actually works instead of designing unsafe behaviors in software, cutting a video into pictures, and processing through screening, labeling and the like to further form the data set. For example, the data sets of unsafe behaviors are provided for monitors in mines and construction sites, so that the quality of the data sets is particularly important for monitoring unsafe behaviors, and the final monitoring and early warning are directly influenced by the unsafe behavior database.
However, unsafe behavior in professional data sets of mines and construction sites is more professional, can be used for classifying navigation less, is unknown for a producer of the data set due to lack of navigation experience, and is difficult to be practically applied to the navigation field. Moreover, as the ship has the characteristics of rolling and pitching, the method for manufacturing the land data set is completely suitable for the ship, so that the manufacturing of the deck cable operation unsafe behavior database which is suitable for the navigation field and can accurately identify and early warn is very necessary.

And secondly, carrying out correlation analysis according to unsafe behaviors obtained by system files and various regulations and actual working experiences. Because practical experience is different from the emphasis of various regulations and files, system files and regulations are more from the viewpoint of protecting normal operation of ships, and practical working experience is more focused on protecting own safety, correlation analysis is carried out on the two materials, and a complete unsafe behavior database is obtained.
After the collection of the unsafe behavior database of the shipman is completed, video sampling is needed, and specific unsafe behavior operation is obtained for further identification. The actual conditions of cable winding and unwinding, cable machine use and deck daily maintenance are shot on the actual ship, and the water staff is required to make protective measures, so that unsafe behaviors in the unsafe behavior database are actually demonstrated under the condition of ensuring safety. Specifically, the video data is decomposed into an original picture data set after being acquired, and subjected to image processing such as graying, median filtering, and the like. Then, through subtraction, addition and iteration of images, a proper threshold value is obtained through experiments of two hundred pictures. Finally, further iteration is carried out, and all pictures to be marked are screened out. After a picture data set to be marked is obtained, a labelimg is used for carrying out frame processing on specific actions to be identified in the image, and marking is carried out on actions of unsafe behaviors, wherein the marking name accords with data in a shipman unsafe behavior database.
Finally, the basic information of the marked unsafe behavior database picture is stored in a picture data table, and the information in the picture data table comprises the picture place, the picture warehousing time and unsafe behaviors contained in the picture; wherein the noted unsafe behavior is an identification of the database picture.
The data set can be used in a crewman unsafe behavior and state early warning platform, and is particularly applied to a semi-outdoor camera, and according to the crewman unsafe behavior and state detection early warning platform, in a specification of application of a river mail wheel, five cameras in total can use the data set as a training set to conduct behavior recognition.

the data set is used as the basis of unsafe behavior detection of deck cable operation, monitoring is carried out on unsafe behavior and state of a crew, special software is adopted for analysis and early warning, and comprehensive, timely and effective big data support is provided for ship safety management. And (5) improving the safety navigation management level of the ship. And then the system outputs network signals to the 4G network switch configured by the ship, so that information sharing between the ship and the shore (a shipborne company, a school laboratory) is realized.
