[0043] Embodiment 2:

[0044] In this embodiment, the monitoring system is installed in the main channel of the ship.

[0045] like Figure 6 and Figure 7 As shown, in the main channel area of ​​the ship, the installation of the monitoring system is crucial to monitor the movements of crew and equipment. The following are the installation steps:

[0046] Fixed steel section:

[0047] On both sides of the main channel of the ship, choose a moderate height from the ground and fix the I-shaped steel 4 on the channel wall. Ensure the parallelism and firmness of the I-shaped steel to support the subsequent installation of monitoring equipment.

[0048] Install the monitor connector:

[0049] The monitor connector 1 is fixed to the I-shaped steel 4 through the extension plate 14. A fixed circular plate 13 is mounted on the extension plate, and the circular plate is adsorbed and connected to the I-shaped steel through a strong magnetic strip 12 to ensure that the device remains stable when the ship vibrates.

[0050] The upper and lower parts of the monitor connector are respectively installed with a gun-type monitor assembly 2 and a ball-type monitor assembly 3. The connector is reinforced by an arc-shaped flip cover 16 and a locking screw 17 to prevent loosening in a vibration environment.

[0051] Camera debugging:

[0052] After installation, adjust the viewing angle and focal length of the camera to ensure that it can fully cover the channel area without blind spots. Finally, fix the angle of the camera by tightening the nut 18.

[0053] System access and debugging:

[0054] Connect the camera to the ship's security system, view the surveillance footage in real time through the system host, and set up recording. Test all connections and functions to ensure the system is operating properly.

[0055] Embodiment 3:

[0056] This embodiment is to install a monitoring system in the ship's engine room area. The ship's engine room is a key safety monitoring area. The following is the implementation method:

[0057] Selection and fixation of I-shaped steel:

[0058] The cabin environment is complex, with high humidity and large temperature changes. Therefore, high temperature resistant and corrosion resistant I-shaped steel materials are selected and fixed on appropriate supporting structures in the cabin to prevent corrosion and deformation.

[0059] Install the monitor connector and camera:

[0060] The monitor connector 1 made of stainless steel is installed on the I-shaped steel. The monitor connector should be firmly connected to the I-shaped steel through an extension plate 14 and a fixed circular plate 13, and equipped with a strong magnetic strip 12 to increase stability.

[0061] The gun-type monitor 21 and the ball-type monitor 31 are installed on the front side of the monitor connector, inserted into the socket 110 through the plug plate 23, and the locking screw 17 is used to ensure that the installation is firm.

[0062] Earthquake-resistant design:

[0063] The cabin vibrates strongly, so during installation, add shock-absorbing pads or use elastic connectors to further reduce camera position changes and image jitter caused by vibration.

[0064] Network and power protection:

[0065] The cabin environment has high requirements for equipment. It is recommended to use cables and connectors with waterproof and dustproof functions, and equip with a redundant power supply system to ensure that the cabin monitoring system continues to operate in harsh environments.

[0066] Embodiment 4:

[0067] This example is a monitoring installation at the hatch of a confined space. The hatch of a confined space is an important area for monitoring. The following is the implementation plan:

[0068] Determination of installation location:

[0069] Select a sturdy location above or around the hatch of the confined space to fix the I-shaped steel 4. Since confined spaces may have high humidity and low temperature environments, the materials should be specially treated to enhance durability.

[0070] Install the monitor connector and camera:

[0071] The monitor connector 1 is installed on the I-shaped steel and fixedly connected to the I-shaped steel through the extension plate 14. The gun-type monitor assembly 2 is installed on the upper front side of the monitor connector, and the ball-type monitor assembly 3 is installed on the lower side.

[0072] To prevent moisture from invading the camera assembly, it is recommended to use a waterproof seal during installation and add a protective cover to the outside of the camera.

[0073] Monitoring angle adjustment:

[0074] Adjust the monitoring angle of the camera so that it can completely cover the hatch area to prevent illegal intrusion and monitoring blind spots. After installation, fix the camera position by locking screw 17 and fastening nut 18.

[0075] Special environment adaptability test:

[0076] After installation, an environmental adaptability test is carried out to simulate extreme conditions in a confined space, such as high humidity, low temperature, low light, etc., to ensure that the monitoring equipment can work normally under these conditions.

[0077] Example 4: Deck area monitoring installation

[0078] Monitoring installation in the ship deck area:

[0079] Installation of I-shaped steel:

[0080] Since the deck area is exposed to the wind and sun, I-shaped steel 4 with special anti-corrosion treatment is selected and fixed to the deck guardrail or supporting structure by bolts or welding.

[0081] Fixing of monitor connector and camera:

[0082] The monitor connector 1 is adsorbed to the surface of the I-shaped steel through the strong magnetic strip 12 and the fixed circular plate 13, and the gun-type monitor 21 and the ball-type monitor 31 are installed. In order to prevent the influence of external factors such as wind on the camera, it is recommended to use a support structure with high wind resistance between the camera and the connector.

[0083] Power and network connection:

[0084] The power supply and network in the deck area need additional protection, using weather-resistant cables to avoid exposure. The power supply system should be equipped with waterproof devices to ensure normal power supply in bad weather.

[0085] Protective measures:

[0086] To cope with special conditions in the marine environment, such as salt spray corrosion, it is recommended to add protective coatings to the camera and connectors and perform protective treatments regularly. For environments with strong winds, you can use a wind and rain cover to protect the camera, and consider the wind direction when installing.

[0087] Embodiment 5:

[0088] This embodiment is a linkage monitoring installation of the safety system, which improves the overall safety by linking with other safety systems of the ship.

[0089] Monitoring system and fire alarm system linkage:

[0090] When installing the camera, a fire detection sensor is integrated. When the fire detector triggers the alarm, the camera automatically adjusts the focus and viewing angle, centrally monitors the fire source area, and stores the video through the host.

[0091] Monitoring system and anti-theft system linkage:

[0092] When the anti-theft system detects an abnormal intrusion signal, the camera in the relevant area immediately locks and tracks the intrusion target, automatically turns on the high-definition recording mode, and transmits the alarm information to the monitoring center in real time.

[0093] Remote control and data backup:

[0094] The system supports real-time viewing and adjustment of cameras through remote control. Operators can access the system through a secure network at any location to monitor the ship's status. At the same time, all video data is automatically backed up to a remote server to ensure data security.

[0095] Regular system self-check and maintenance reminders:

[0096] The system automatically performs self-checking procedures regularly to detect the operating status of all equipment and promptly informs maintenance personnel when abnormalities are found. The system also records the working hours and environmental parameters of the equipment and automatically reminds maintenance operations that need to be performed.

[0097] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention.
