Description

Technical Field

[0001] This utility model relates to the technical field of port operation monitoring equipment, specifically to a ship that facilitates monitoring of cranes loading and unloading cargo from the hull and a safety system using it. Background Technology

[0002] In recent years, the industrial monitoring industry has developed rapidly, and the technology of the monitoring industry has also made great progress. It has gradually integrated with other industrial fields, greatly improving productivity, providing convenience for operators, and ensuring safe production.

[0003] Ship unloaders and gantry cranes have become essential loading and unloading equipment in ports due to their simple structure, high maneuverability, fast loading and unloading speed, and convenient operation. However, in recent years, due to various reasons, safety accidents have occurred frequently, causing serious consequences. These accidents mainly involve collisions with nearby personnel and vehicles during operation.

[0004] These accidents are caused not only by subjective factors such as drivers violating driving regulations, failing to observe the surrounding environment, and neglecting to pay attention to the vehicle's driving status, but also by objective factors such as equipment being too high or too large, having too narrow a field of vision, and having too many blind spots, making it difficult for drivers to judge the surrounding environment and operating status. To prevent such accidents, measures need to be taken to enable drivers to obtain real-time information about their surroundings. During operations, if any object or person is detected approaching, the driver must be notified promptly, allowing them sufficient time to assess the situation and take appropriate action. Utility Model Content

[0073] 2. Enhance operational safety

[0074] Reduced accidents: Because the driver can clearly observe the position of cargo, personnel and other machinery inside hold 9, the risk of collisions and crushing accidents during operations is greatly reduced.

[0075] Eliminating blind spots: This system reduces blind spots in cabin 9, allowing the operator to be more careful and avoid improper operation of personnel or equipment;

[0076] 3. Improve adaptability to the working environment

[0077] Enhanced stability in harsh environments: The dome camera 2 has an IP66 protection rating, enabling it to work stably in the harsh environment of the port, unaffected by external factors such as wind and rain;

[0078] Stable transmission over long distances: Utilizing 2.4G and 5G wireless communication technologies, stable transmission of video signals can be ensured even when the hatch and the control room are far apart.

[0079] 4. Reduce operating costs

[0080] Reduced maintenance and accident costs: Because the system improves operational safety and accuracy, it reduces the probability of equipment damage and accidents, thereby lowering maintenance costs and potential accident compensation costs;

[0081] Saves labor costs: The system enables unmanned command operations, reducing the need for on-site command personnel and thus saving labor costs;

[0082] 5. System flexibility and compatibility

[0083] Portability: The design of the hemispherical camera 2 and the miniaturized battery pack 5 makes the system easy to carry and deploy quickly, suitable for a variety of ships and operating environments;
