Problems solved by technology

At present, the video recording of this part is mainly through the NVR to record the whole process of the camera. After the recording is completed, the corresponding video file is found through the time for the top video that needs to be viewed, and then the video is cut or spliced; however, this method requires manual work. For processing, there are many video files recorded at the same time, which are large and difficult to find
At the same time, due to the limitation of the network in the maritime environment, if the video recorded in the whole process is directly uploaded or stored locally, there will be time-consuming and space-consuming problems. Therefore, it is necessary to cut or merge the video, which has great impact on The professional skills of ship personnel put forward higher requirements

Embodiment 1

[0079] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0080] The present invention provides a video recording method based on an operation and maintenance ship for wind turbines against top, comprising the following steps:

[0081] S1. Obtain the position information of the operation and maintenance ship and calculate the distance between the position information of the operation and maintenance ship and the target wind turbine; step S1 is specifically:

[0082] S11. Obtain the position information of the operation and maintenance ship, compare the position information of the operation and maintenance ship with all the maintained wind field ranges, and determine whether the operation and maintenance ship has entered the first wind field in all the maintained wind field ranges range, if so, send a video recording warning message and record the warning status; all maintained wind farm ranges include the first wind farm range;

[0083] S12. Obtain the en...

Embodiment 2

[0115] Please refer to figure 2 , the second embodiment of the present invention is:

[0116] A fan-top video recording system based on an operation and maintenance ship, including one or more processors 1 and memory 2, the memory 2 stores a program, and when the program is executed by the processor 1, the following steps are implemented:

Abstract

The invention relates to the technical field of operation and maintenance ship video collection, in particular to a fan abutting video recording method and system based on an operation and maintenance ship. The method comprises the steps of obtaining position information of an operation and maintenance ship and calculating the distance between the position information of the operation and maintenance ship and a target fan; when the distance is smaller than the first preset threshold value, whether the engine rotating speed of the operation and maintenance ship is larger than a second preset threshold value or not and whether the navigational speed of the operation and maintenance ship is smaller than a third preset threshold value or not are judged; if so, starting a camera device arranged on the operation and maintenance ship to carry out abutting video recording, and determining whether the navigational speed of the operation and maintenance ship is larger than a third preset threshold value or not; if yes, determining whether the distance between the position information of the operation and maintenance ship and the target fan is larger than a first preset threshold value or not; if yes, stopping operation of the camera device to obtain the abutting video file. Through comprehensive analysis of the dynamic parameters of the operation and maintenance ship and the position information of the target fan, the jacking moment of the operation and maintenance ship can be automatically identified, the recording duration of the fan jacking video is greatly shortened, and the system utilization rate is improved.

Description

technical field [0001] The present invention relates to the technical field of video acquisition of an operation and maintenance ship, in particular to a method and system for recording a wind turbine leaning against a ship based on an operation and maintenance ship. Background technique [0002] When the offshore wind power operation and maintenance ship implements the operation and maintenance of the wind turbine, it needs to lean against (close to) the operation and maintenance channel of the wind turbine, so that the operation and maintenance personnel and operation and maintenance materials can be transferred from the ship to the wind turbine platform. Because the operation and maintenance ship needs to lean against the wind turbine when it leans against the wind turbine, and at the same time, it is necessary to record the process of the ship leaning against the wind turbine and the process of the operation and maintenance personnel boarding the wind turbine. At present...
