[0040] The self-powered module 1 includes a vertical axis turbine located underwater and a generator installed on the top of the hull 2. The rotation of the vertical axis turbine is used to capture water flow energy and convert it into electrical energy through the generator.

Two groups of gun-type cameras 501 and ball-type cameras 502 can autonomously identify illegal and irregular behaviors within the visual range of the camera through the independently developed visual recognition algorithm, and two groups of condensers 504 ensure the normal use of the camera in cloudy and other environments with insufficient light; a group of wind speed and direction meters 505 and AIS modules 506 can measure the natural climatic conditions such as wind speed and direction that affect the normal navigation of ships and ship information such as the ship number of navigable ships all day long; two groups of speakers 503 can receive signals from the industrial computer 601 and give voice warnings to illegal and irregular ships / individuals, and can also promptly remind dangerous ship behaviors such as mistaken entry into prohibited navigation areas and ship fires.

[0050] Specific implementation method five: Figures 1 to 5 As shown, a warning strobe light 7 is also included;

[0051] The warning strobe light 7 is installed on the side of the roof of the upper structure 3.

[0052] Among them, the warning strobe light 7 can warn navigable ships in low visibility scenes such as heavy fog, reducing or avoiding the collision of ships with safety guards due to poor visibility.

[0053] Specific implementation method six: Figures 6 to 10 As shown, the self-powered module 1 includes a vertical axis impeller 101, a rotating shaft 102, an accelerator 103, a generator 104, a converter 105, an energy storage power supply 106 and a fixing frame 107;

[0054] The rotating shaft 102 is installed in the lower part of the hull 2 ​​through a fixing frame 107, and the vertical axis impeller 101 is coaxially fixedly installed at the lower end of the rotating shaft 102.

[0056] The converter 105 can adjust the electric energy generated by the generator 104 to the voltage required by each monitoring module of the water guard for water safety supervision and law enforcement.

[0057] The energy storage power supply 106 is installed on the hull, and can store the remaining electric energy after being used by the various monitoring devices of the water guard, and assist the vertical axis turbine to maintain the normal operation of the various monitoring modules of the water guard when the water flow conditions are poor.

[0058] The accelerator 103 is installed above the rotating shaft 102 , and adjusts and accelerates the rotation speed of the vertical axis turbine 101 to the optimal power generation rotation speed range of the generator 104 through a planetary gear structure.

[0059] The vertical axis impeller 101 is driven by the water flow to rotate the rotating shaft 102, thereby capturing the water flow energy; the self-powered module 1 adopts an all-weather energy self-sustaining design, and through the vertical axis power generation and energy supply design, it can achieve the all-weather, all-time, environmentally friendly energy supply required by water guards for safety supervision and law enforcement, thereby realizing the self-sustaining operation of the present invention.

[0060] How it works

[0061] When the present invention is working, it relies on the hull 2 ​​to stay on the water surface and maintain stability; the self-powered module 1 is arranged under the hull 2 ​​to capture water flow energy, and converts the captured water flow energy into electrical energy through the generator arranged on the hull 2;

[0062] The safety supervision system 5 obtains power supply through the generator to realize all-weather safety supervision of the waterway, and transmits the identified illegal and dangerous behaviors to the industrial computer 601; the industrial computer 601 receives information, uploads it to the cloud platform, and processes the input information and outputs it to the outside of the system through the speaker 503 and the photoelectric output screen 4;

[0063] The warning strobe light 7 continuously reminds the position of the safety guards of the passing ships by flashing, so as to prevent the passing ships from colliding with the safety guards due to obstructed vision, and also reminds the passing ships that they have entered the safety supervision range.

[0064] When the self-powered module 1 is working, it is fixed on the hull by the fixing frame 107 to achieve the stability of the energy supply module. The vertical axis impeller 101 is driven by the water flow to rotate, capture the water flow energy, and drive the accelerator 103 through the rotating shaft 102 to accelerate the speed of the vertical axis turbine to the optimal power generation efficiency speed range of the generator 104;

[0065] The generator 104 receives the energy speed input from the vertical axis turbine and the accelerator 103, converts it into electrical energy, and outputs it to the converter 105; the converter 105 adjusts the voltage of the electrical energy transmitted by the generator 104 and supplies it to various monitoring equipment of the water guard.

[0066] The energy storage structure 106 stores the remaining electrical energy and assists the vertical axis turbine 101 to maintain the normal operation of various monitoring equipment of the water guard when the water flow condition is poor.

[0067] The steps of the detection and identification method used in the present invention include:

[0068] Step 1: construct a data set, which includes a target ship data set and a river and sea channel condition data set; the ship data set includes the ship number and ship type;

[0069] Step 2: Establish an image and video stitching algorithm. Based on Gaussian filtering and SURF algorithm, different convolution cores are used to convolve the channel video stream from the camera, and the stitching points of the channel scenes in the two video streams are identified; the stitching points are compared, and the stitching points with high similarity in the two video streams are connected one by one to realize the stitching of the two channel video streams into a real-time panoramic channel video stream;

[0070] Step 3: Train the data set in step 1 in batches, use different grouping methods to train the recognition network, and improve the accuracy and reliability of the recognition network; specifically include:

[0071] Step 301, ship speeding identification: identify the ship's characteristics when the ship is sailing, compare the ship's characteristics with those previously identified when identifying the image next time, and identify the ship's speed in the channel by comparing the ship's positions at different times; when it is identified that the ship's speed exceeds the maximum allowable speed of the channel, an alarm is automatically issued and the current ship characteristics are recorded;

[0072] Step 302, identifying ships that have crossed the boundary or entered the prohibited navigation zone; by dividing the prohibited navigation zone in advance, the characteristics of the ships in the channel are identified. When a ship in the prohibited navigation zone is identified, an alarm is automatically issued and the characteristics of the currently identified ship are recorded;

[0073] Step 303, ship overdraft identification: using a camera to identify the distance between the ship's waterline and the water surface, and automatically sounding an alarm when the identified ship's waterline is abnormal, and recording the current ship characteristics;

[0074] Step 304, ship fire identification: using the temperature recognition technology carried by the gun-type camera, based on edge detection, the temperature change of the navigable ship is detected; when it is found that the edge temperature change of the ship is abnormal, an alarm is automatically issued, and the current ship information is recorded and output to the cloud platform to remind the ship and waterway management department to handle it;

[0075] Step 4: Perform image recognition on the spliced ​​video streams, determine the ship information such as ship number, draft, etc. in the spliced ​​panoramic video of the waterway based on different image recognition features, and handle the identified illegal and irregular behaviors of the ships.

[0076] The above recognition method is designed with a panoramic video stitching algorithm, which can stitch the real-time video streams of two cameras into a panoramic video based on the stitching algorithm. On the one hand, it can achieve full coverage of the waterway scene, and on the other hand, it can also provide a panoramic video of the waterway for the illegal and irregular behavior recognition algorithm;

[0077] The above identification method relies on image recognition algorithms and can accurately identify illegal and irregular behaviors in the waterway with the help of camera terminals equipped with recognition algorithms. In addition, multiple recognition algorithms can identify different illegal and irregular behaviors, which improves the versatility of the device and enhances the effect of waterway supervision.

[0078] The above-mentioned identification method utilizes multiple camera visual perception terminals + exclusive visual recognition algorithms to realize unmanned waterway safety supervision, greatly reduces the use of manpower, and has advantages in economic benefits.
