The ship itself has multiple metal structural parts, such as hull steel plates, cabin steel plates, and exhaust pipe steel plates. These metal structural parts are exposed to the external environment of the ship, so they will be exposed to sunlight, wind and rain erosion , Ocean current invasion and wave beating. Under such an external environment, the metal fatigue of these structural parts made of metal will also increase accordingly.

For general means of transportation, such as automobiles or locomotives, the metal fatigue of the body steel plate or door steel plate is too high, and at most only cracks occur, but because they are walking on the road and rely on wheels, the road surface is probably not too bumpy The apparent external force will affect the balance and safety of the car or locomotive, so it will not cause accidents because the metal fatigue of the body steel plate or door steel plate is too high. However, for a ship, once the metal fatigue of the structural parts made of metal increases, causing cracks in the hull steel plate, cabin steel plate, and exhaust pipe steel plate, it will affect its balance and safety, leading to accidents.

On the other hand, ship maintenance requires more manpower, and the time to deploy consumables is even longer.

In order for the examiners to understand the technical features, content and advantages of the new model and the effects it can achieve, the new model is hereby combined with the accompanying drawings and described in detail in the form of embodiments as follows, and the drawings used therein, its The purpose is only for illustration and auxiliary instructions, and may not be the true proportion and precise configuration of the new model after implementation. Therefore, the scale and configuration relationship of the attached drawings should not be interpreted to limit the scope of rights of the new model in actual implementation. Together first describe.

In this model, the definition of metal fatigue of structural parts can refer to https://zh.m.wikipedia.org/zh-tw/%E9%87%91%E5%B1%AC%E7%96%B2% E5%8B%9E. Metal fatigue of structural parts refers to the degree of structural deterioration of metal objects due to continuous dynamic stress. The dynamically changing stresses that cause fatigue in structural members are usually much smaller than the static ultimate tensile or ultimate yield stresses. In other words, the fatigue of structural parts refers to the gradual and local structural damage process, which is caused by long-term accumulation, and the resulting fracture damage often occurs without warning, which may directly lead to accidents (such as air crashes and cargo ship crashes) , so relevant prevention, inspection, and treatment are extremely important.

Typically, fatigue phenomena occur when structural members are repeatedly stressed. Fatigue can be roughly divided into three stages. If the stress exceeds a certain threshold, tiny cracks will form at high stress concentration points (the above high stress concentration points include surface scratches, sharp fillets, keyways, gaps, etc.). Then, with each cycle of stress, the crack gradually expands. Finally, once the crack reaches a critical size, the crack will propagate rapidly, causing the object to fracture directly. The shape of the object design can significantly affect the fatigue life, for example, square holes and sharp grooves will increase the local stress and cracks are more likely to occur. On the contrary, if it is changed to round holes and smooth grooves, cracks are less likely to occur.

In order to detect the metal fatigue of the structural parts, the sensor module with multiple sensors is correspondingly arranged around the structural parts of the ship. Sensors such as but not limited to optical detectors, strain gauges, acoustic sensors, wave detectors, wave height detectors, humidity sensors, temperature sensors, pH detectors, air pressure sensors, wind speed sensors and wind pressure sensors. The optical detector can check the crack size of the high stress concentration point of the structural part, and through the crack size, the metal fatigue degree of the structural part can be known. The strain gauge is the stress applied to the structural part. When the stress applied to the structural part exceeds a certain threshold and lasts for a period of time, the metal fatigue of the structural part will increase. Acoustic sensors, such as microphones, can detect whether the metal fatigue of structural parts has increased by detecting sound fluctuations. When the metal fatigue of structural parts increases, structural parts may additionally vibrate or vibrate during the ship's driving, so The metal fatigue of structural parts can be known by detecting sound waves.

Humidity, temperature, the pH value of the surrounding environment, and the surrounding air pressure are all factors that cause changes in the metal fatigue of structural parts. For example, in a corrosive environment (more acidic or more alkaline environment), the fatigue of structural Higher fatigue), so humidity sensors, temperature sensors, pH detectors and air pressure sensors can detect the above factors and be used to calculate the metal fatigue of structural parts. The wave height sensor and wave sensor can sense the wave height and wave impulse encountered by the hull steel plate. The higher the wave will generate a higher downward force, so it is easier to increase the metal fatigue of the hull steel plate. Similarly, the greater the wave impulse, the easier it is to increase the metal fatigue of the hull steel plate. The wind speed sensor and the wind pressure sensor are used to sense the wind speed and wind pressure suffered by the structural member. When the wind speed and wind pressure suffered by the structural member are greater, it means that the metal fatigue degree of the structural member may increase more. Simply put, any factor that affects the metal fatigue of structural parts can be detected by the sensor to calculate the metal fatigue of structural parts.

The new model can establish the metal fatigue calculation model of each structural part through the collected data, and the metal fatigue calculation model can be obtained through regression analysis or training neural network. After obtaining the metal fatigue degree calculation model of each structural part, the metal fatigue degree calculation model of the structural part can be used to calculate the metal fatigue degree of the structural part according to a plurality of sensing signals. Then, the calculated fatigue degree of each structural part is sent to various types of suggestion modules, such as ship navigation suggestion module, structural reinforcement suggestion module and ship design suggestion module, and these suggestion modules will generate corresponding suggestions For ship drivers, ship maintenance personnel and ship designers to effectively use the calculated metal fatigue of each structural member.

For example, when the hull steel plate at the bottom is subjected to a large ocean current, causing the metal fatigue of the hull steel plate at the bottom to increase to a certain threshold, the ship navigation advice module will advise the driver to try to avoid the underwater ocean current Sailing on the same path, so as to avoid serious damage to the hull steel plate at the bottom, resulting in accidents. As another example, when the metal fatigue degree of the hull steel plate of a certain height of a ship sailing near the offshore of a specific area is often impacted by waves, resulting in a higher metal fatigue degree than the metal fatigue degree of other parts of the hull steel plate , then the ship design suggestion module will suggest that ship designers design ships for offshore navigation in this specific area to strengthen the design of hull steel plates of a specific height, so that the ship can increase its endurance for offshore navigation in this specific area. To give another example, when a ship is about to call at a port, if the metal fatigue of some structural parts is close to a certain threshold, although the fatigue level has not reached a certain threshold, the structural reinforcement suggestion module will advise ship maintenance personnel to adjust and When the ship is in port, the reinforcement and maintenance of the structural parts are carried out.

Next, please refer to FIG. 1 . FIG. 1 is a schematic diagram of a ship with a metal fatigue detection and feedback device in an embodiment of the present invention driving on the sea, which is realized according to the above-mentioned new concept. The ship 1 includes a sensor module formed by a plurality of sensors 110 , a metal fatigue detection feedback device 12 and a plurality of structural components 13 , and the plurality of sensors 110 are arranged on or around the plurality of structural components 13 . The structural member 13 can be any piece of hull steel plate, cabin steel plate, exhaust pipe steel plate or other metal objects that are in contact with the external environment.

The plurality of sensors 110 are, for example but not limited to, optical detectors, strain gauges, acoustic sensors, wave detectors, wave height detectors, humidity sensors, temperature sensors, pH detectors, Air pressure sensor, wind speed sensor and wind pressure sensor. The multiple sensors 110 sense the multiple structural components 13 and generate multiple sensing signals, wherein each structural component 13 is configured with at least one sensor 110 .

In a plurality of structural members 13, the hull steel plates at the bottom are attacked by ocean currents, therefore, the installed strain gauges may measure a huge applied stress, and the installed optical detectors may detect that the cracks gradually expand; the water surface The steel plates on the hull are beaten by waves, and the wave detectors and wave height detectors installed can measure the thrust and high wave height of larger waves; the steel plates in the cabin are beaten by wind and rain, so the wind speed sense The detector and wind pressure sensor can measure higher wind speed and wind pressure; and the exhaust pipe steel plate is exposed to the sun, so the set humidity sensor and temperature sensor can measure lower humidity and higher wind pressure. high temperature etc. Of course, the above-mentioned sensing by the plurality of sensors 110 is an example, and the present invention is not limited thereto.

The metal fatigue detection and feedback device 12 is set in one of the ships 1, such as the control cabin, but the present invention is not limited thereto. The metal fatigue degree detection and feedback device 12 calculates the metal fatigue degree of each structural member 13 according to more than one sensing signal, and generates various suggestions according to the metal fatigue degree of each structural member 13, for example, the metal fatigue degree detection and feedback device 12 to generate sailing suggestions to the driver, the metal fatigue detection and feedback device 12 to generate reinforcement suggestions to ship maintenance personnel, and/or the metal fatigue detection and feedback device 12 to generate design suggestions to ship designers.

Please refer to FIG. 1 and FIG. 2. FIG. 2 is a schematic block diagram of a ship with a metal fatigue detection and feedback device according to an embodiment of the present invention. The metal fatigue detection feedback device 12 includes a calculation processing core 120, a communication module 125, and a sensing signal storage module 126, wherein the processing core 120 is electrically connected to the sensing signal storage module 126, and the sensor module 11 is electrically connected.

The processing core 120 is composed of multiple hardware circuits, and its functions can be realized solely by the hardware circuits, or by combining the hardware circuits with software and firmware, and the present invention is not limited thereto.

The multiple sensors 11 of the sensor module 110 respectively sense factors related to metal fatigue of the structural member 13 , and transmit the generated sensing signals to the sensing signal storage module 126 for storage. Multiple hardware circuits of the processing core 120 are configured into a metal fatigue calculation module 121 , a ship navigation suggestion module 122 , a structural reinforcement suggestion module 123 and a ship design suggestion module 124 . As mentioned above, the metal fatigue degree calculation module 121 has a metal fatigue degree calculation model of each structural part, and the metal fatigue degree calculation model can be obtained through an existing model training algorithm as described above. The metal fatigue degree calculation module 121 calculates the metal fatigue degree according to at least one sensing signal corresponding to each structural component 13 . For example, the optical detector detects the structural member 13 to detect cracks in the hull steel plate, and the metal fatigue calculation model calculates the fatigue increase according to the increase in the size of the crack in the hull steel plate, for example, the increase in the crack size and the metal fatigue The degree of increase exhibits an exponential relationship.

After the metal fatigue degree calculation module 121 calculates the metal fatigue degree of each structural part 13, the metal fatigue degree of each structural part is sent to the ship navigation suggestion module 122, the structural reinforcement suggestion module 123 and the ship design suggestion module 124 . The ship navigation suggestion module 122 will give the ship driver navigation suggestions according to the metal fatigue of each structural member 13 . For example, when the metal fatigue of the side hull plate reaches a certain threshold, it means that the turn of ship 1 should be reduced, because the turn will cause more waves to cause more damage to the metal fatigue of the side hull plate Therefore, the ship navigation suggestion module 122 may advise the ship operator to turn less, turn slowly (ie, suggest a specific driving style), or indicate a route with less turning (ie, suggest a specific route) and the like. For another example, when the metal fatigue of the exhaust pipe steel plate exceeds a certain threshold due to wind and rain, the ship sailing suggestion module 122 will suggest the ship driver to switch to a route with less wind and rain.

The structural reinforcement suggestion module 123 transmits structural reinforcement suggestions to the ship maintenance personnel according to the metal fatigue degree of each structural part 13, so that the ship maintenance personnel can carry out the expected assignment and adjustment, so that when the ship 1 is in port, it can Immediately reinforce or replace the structural parts 13 with high metal fatigue (that is, the metal fatigue exceeds a certain threshold value), so as to increase the safety and endurance of the ship 1's next departure voyage, and at the same time reduce the number of ships 1 Waiting time for port maintenance. The ship design suggestion module 124 generates relevant ship design suggestions to the ship designer according to the metal fatigue degree of each structural part 13, and the ship designer can therefore use the metal fatigue degree of each structural part 13 in a specific environment, a specific area or a specific route How to design a suitable ship 1 to increase the safety and endurance of the ship 1 in a specific environment, a specific area or a specific route. The ship navigation suggestion module 122 , the structural reinforcement suggestion module 123 and the ship design suggestion module 124 can send suggestions to corresponding ship drivers, ship maintenance personnel and ship designers through the communication module 125 .
