Therefore, an intelligent and adaptive mast lifting control system is needed.

[0004] Specifically, the following problems exist:

[0018] The content expressed in each drawing in the utility model specification is briefly described as follows:

[0019] Figure 1 It is a ship mast lifting control system principle diagram. DETAILED DESCRIPTION

[0020] The specific embodiment of the utility model is further described in detail as the shape, structure, mutual position and connection relationship between parts, the role and working principle of each part, manufacturing process and operation method, etc. of each component involved, by comparing the drawings and describing the embodiments, to help the skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the utility model.

[0021] The ship mast lifting control system adopts a mast with telescopic function, which is composed of a base tower and a device platform fixed on the base tower. Only the lifting platform can ensure that the mast can pass through the large section height limit area, and the signal receiving effect can be increased by lifting the mast. The device platform is a platform for installing electronic devices on the original mast (any shape can be designed as needed, such as a flat structure). The electronic devices include radar, communication antennas, navigation lights, etc.

[0022] The device platform and the base tower are connected by a lifting mechanism, which changes the distance between the device platform and the base tower. The lifting mechanism is a vertical telescopic hydraulic lifting device or a servo motor lifting device. Limit switches and overload protection devices can be installed between the device platform and the base tower to ensure safety. In order to increase the telescopic range of the mast, the base tower is composed of multiple support platforms with gradually increasing areas from top to bottom. Each layer of support platforms is connected by a lifting mechanism. Through the cooperation of multiple telescopic structures, a larger range of mast lifting can be achieved with a conventional size lifting mechanism. Because the lifting range of the mast is increased, an area for placing cables on the deck beside the mast is needed. The cables connecting the electronic devices on the device platform are located on one side of the mast. When the mast is extended, the cables are straightened. When the mast is lowered, the cables will automatically stack on one side of the mast. Of course, the cables can also be straightened and fixed in sections on the sides of the device platform and the support platforms. The cables will be bent in sections to avoid excessive stacking on the deck.

[0023] The above-mentioned mast structure is a segmented telescopic design (carbon fiber / aluminum alloy composite material), with an internal guide rail to ensure vertical lifting precision and stability. Three lifting mechanisms are provided between the first support platform and the second support platform fixed on the deck. Because the overall support has the largest mass and multiple support points, the reliability of the support can be improved. The lower surface of the device platform is provided with a downward vertical limiting rod, and the base tower is provided with a limiting hole matched with the limiting rod. The lower surface of the third and subsequent support platforms is provided with a downward vertical limiting rod, and the support platform is provided with a limiting hole matched with the limiting rod. When designing, it is necessary to ensure that each layer of limiting rods does not interfere downward. The limiting rod can improve the reliability of the lifting process and reduce the frequency and amplitude of mast shaking.

[0024] Each lifting mechanism is driven and controlled by a driving unit. The driving unit ensures that it can still operate in the event of a single point failure. The driving unit is controlled by a central processor. The output end of the central processor is connected to the driving unit through a signal line. The interactive port of the central processor is connected to the human-computer interaction interface. The human-computer interaction interface can display relevant parameter information and control the system, i.e. control the telescoping of the mast.

[0025] In addition, the system can also be added with automatic control function or monitoring function, that is, the input end of the central processor is connected with a sensor module, the sensor module is used for sensing the surrounding environmental parameters, and the sensor module comprises:

[0026] Laser radar / millimeter wave radar: detecting the height and distance of the front obstacle;

[0027] Wind speed sensor: monitoring real-time wind pressure and triggering a wind-resistant mast lowering strategy;

[0028] Water depth sensor: combining with an electronic chart to predict the safety height of the mast.

[0029] The central processor (ECU) can integrate sensor data as needed, generate lifting instructions through an AI algorithm, or manually control after judging relevant data, and the connected machine interaction interface supports manual mode and preset height mode (such as "cruise mode" and "port mode"). The communication port of the central processor is connected with a communication module, the communication module is linked with a ship navigation system (GPS / AI S), and the navigation route height limit data is preloaded

[0030] Taking a certain type of cargo ship as an example, the mast height is 15 meters, and the maximum lifting speed is 0.5 m / s. When the ship approaches a bridge with a height limit of 12 meters:

[0031] The laser range finder detects that the remaining height is 3 meters, triggering an early warning;

[0032] The controller analyzes the wind speed (5 levels) and the ship inclination (<3°), determines the safety, and starts to descend;

[0033] The mast is manually controlled or automatically controlled to descend to 10 meters at a speed of 0.3 m / s, and is automatically reset after passing through the bridge.

[0034] The above has been described by way of example in combination with the drawings, and it is obvious that the specific implementation of the utility model is not limited by the above mode, as long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the concept and technical scheme of the utility model are directly applied to other occasions without improvement, all of which are within the protection scope of the utility model.
