Description

Technical Field

[0001] The invention relates to the technical field of ship load detection, in particular to a ship overload detection alarm monitoring device. Background Art

[0002] When fishing boats go out to sea, the load of the boat directly affects its safety, stability and navigation efficiency. Reasonable load can ensure that the draft and center of gravity of the boat are within a safe range, ensure the stability of the hull, and avoid tilting or capsizing of the boat due to overloading. Excessive load not only increases the sinking depth of the boat, but may also cause structural damage, increase fuel consumption and reduce speed, thus affecting navigation efficiency and safety.

[0003] However, in the prior art, when a ship is operating at sea, it is impossible to monitor in real time whether the cargo on the ship is overweight. In order to increase the efficiency of fishing boats, when the cargo is overweight, the inland cannot provide a warning of danger to the operating ship, thereby increasing the risk of the ship's operation at sea. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a ship-based overweight detection alarm monitoring device, which solves the problem that fishing boats cannot monitor in real time whether the load exceeds the standard during sea operations, and cannot issue an early warning in time when overweight.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a marine overweight detection alarm monitoring device, comprising: The hull has a satellite terminal body installed inside for receiving and sending messages; A sensor, which is mounted on the outer wall of the hull, is used to detect the relative position of the sea level and the highest waterline, and is connected to the plug interface of the satellite terminal body through a communication line; The controller is used to receive the data of the relative position of the sea level and the highest waterline, and calculate the load information of the hull through the data of the relative position.

[0006] Preferably, the sensor includes one of a liquid level sensor or a pressure sensor.

[0007] Preferably, when the sensor is a liquid level sensor, the liquid level sensor is installed at the highest waterline of the hull and is lower than the highest waterline.

[0008] Preferably, when the sensor is a pressure sensor, the pressure sensor is installed on the outer wall of the hull and is below the sea level when the hull is unloaded.

[0009] Preferably, the controller comprises: A data receiving and denoising unit is used to receive data from sensors and perform denoising to ensure the accuracy of the data; A data processing and calculation unit, used for calculating the load information of the hull based on the denoised data; The early warning judgment and alarm unit determines whether the calculated ship load information exceeds the preset maximum load and triggers an alarm signal when it is overloaded. At the same time, the alarm signal is transmitted to the land control center through the satellite terminal body; The path planning and weather information unit is used to receive the destination, route, and real-time weather data set by the crew, and send them to the data processing and calculation unit. At this time, the data processing and calculation unit recalculates the maximum load of the hull based on the wind and wave information.

[0010] Preferably, in the data processing and computing unit: When the sensor is a liquid level sensor, the steps of the data processing and calculation unit calculating the maximum load of the hull are: when the liquid level of the vessel reaches or exceeds a preset maximum waterline; The data processing and calculation unit determines whether the sea level submerges the highest waterline by comparing the difference between the current sea level and the highest waterline; When the sensor is a pressure sensor, the steps for the data processing and calculation unit to calculate the maximum load of the hull are: The pressure sensor can be used to calculate the draft of the ship by measuring the pressure value at different water depths under different load conditions. The actual load of the hull is obtained based on the difference between the draft and the light load depth of the hull.

[0011] Preferably, in the path planning and meteorological information unit, the meteorological data includes wind force, wind direction and wave strength, and the data processing and calculation unit recalculates the maximum load of the hull at this time according to the wind force, wind direction and wave strength.

[0012] Preferably, the controller also includes a data recording and monitoring unit for recording the vessel's load data, weather conditions, route information and alarm history in real time to facilitate subsequent analysis and supervision.

[0013] The present invention provides a ship overweight detection alarm monitoring device, which has the following beneficial effects: 1. The present invention detects the relationship between the sea level and the highest waterline of the hull in real time through sensors, and then calculates the load of the hull, which solves the problem that the overweight of the ship cannot be discovered in time and ensures the stability and safety of the ship during operation.

[0014] 2. When the sensor is a liquid level sensor, it can detect the height difference between the sea level and the waterline of the ship in real time, and calculate the load of the ship according to the change of the liquid level; the working principle of the liquid level sensor is based on the fluctuation of the liquid level of seawater. When the load of the ship changes, the liquid level sensor will accurately sense the change of the waterline; on the contrary, when the sensor is a pressure sensor, the pressure sensor measures the water pressure at the location of the hull, and then calculates the draft depth of the hull, and calculates the current load based on this depth; therefore, it can achieve higher-precision load detection capabilities, effectively reducing the impact of factors such as waves and tides, and ensuring the accuracy and reliability of ship load monitoring.

[0015] 3. The present invention can dynamically adjust the maximum load of the ship according to the real-time meteorological conditions through the path planning and meteorological information unit in the controller, ensuring that the ship can maintain safe navigation in different sea conditions. Compared with the existing technology that cannot adjust the load according to external factors such as wind and waves, the present invention can respond to changes in wind force, wind direction and wave intensity in real time, effectively reduce the risk of overloading and improve navigation safety.

[0018] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In order to better understand the present invention, the above contents are described in detail below in conjunction with specific embodiments.

[0020] Please see attached Figure 1 -Attached Figure 4The embodiment of the present invention provides a ship overweight detection alarm monitoring device, which is characterized by comprising: a hull 1, in which a satellite terminal body 2 is installed, which is used to receive and send messages; a sensor 4, which is installed on the outer wall of the hull 1, and is used to detect the relative position of the sea level 7 and the highest waterline 8, and is connected to the plug interface 6 of the satellite terminal body 2 through a communication line 5; a controller 3, which is used to receive data on the relative position of the sea level 7 and the highest waterline 8, and calculate the load information of the hull 1 through the relative position data.

[0021] In this embodiment, the sensor 4 can be used to collect information on the sea level 7. By inserting the communication line 5 into the plug interface 6, the controller 3 and the sensor 4 can be connected, and the information collected by the sensor 4 can be processed and calculated, so as to know the relationship between the current highest waterline 8 outside the hull 1 and the sea level 7, so as to know whether the sea level 7 submerges the highest waterline 8 of the hull 1. When the sea level 7 submerges the highest waterline 8, it means that the hull 1 is overloaded at this time, and then the controller 3 can generate an alarm to remind the crew that the hull 11 is overloaded. At the same time, the overload information can also be transmitted to the land control center through the satellite terminal body 2; In addition, the IoT communication method can be used to further enhance the intelligence and flexibility of the ship's overweight detection alarm monitoring device. By integrating the IoT communication module, the ship can transmit real-time data with the external control center or cloud platform through wireless networks (such as Wi-Fi, LTE, 5G, etc.), instead of relying entirely on satellite communications. The IoT device will be responsible for collecting data from sensors (including data from liquid level sensors and pressure sensors) and transmitting these data to the remote server or local control center in real time through the wireless network, ensuring that the monitoring personnel can obtain key data such as the ship's load information, the relative position of the sea level and the waterline at any time. In the case of an overweight ship, the IoT communication will promptly send an alarm signal to the control center to remind the crew to take necessary safety measures. Through the IoT system, the crew can also achieve remote adjustment and maintenance to ensure the normal operation of the equipment. In addition, the IoT also provides powerful data storage and analysis functions, which can provide data support for the long-term operation of the ship and help optimize navigation efficiency and safety management. In this way, the system no longer relies solely on satellite communications, but can also provide more stable and efficient communication solutions in areas covered by wireless networks, improving the real-time response capability and reliability of the system.

[0022] The sensor 4 includes a liquid level sensor or a pressure sensor. When the sensor 4 is a liquid level sensor, the liquid level sensor is installed at the highest waterline 8 of the hull 1 and is lower than the highest waterline 8. When the sensor 4 is a pressure sensor, the pressure sensor is installed on the outer wall of the hull 1 and is below the sea level 7 when the hull 1 is unloaded.

[0023] In this embodiment, when the sensor 4 is a liquid level sensor, it is installed outside the hull 1 at a position lower than the highest waterline 8. Therefore, when the sea level 7 submerges the highest waterline 8, the liquid level sensor will also be submerged. At this time, the liquid level sensor will transmit a signal to the controller 3, which is the maximum load of the hull 1. When the sensor 4 is a pressure sensor, it is installed at the bottom of the ship and is below the sea level 7 when the hull 1 is unloaded. Therefore, when the load of the hull 1 becomes heavier, the hull 1 will gradually enter the water, that is, the water depth where the pressure sensor is located will gradually increase, so the water pressure on the pressure sensor will also gradually increase. The control unit receives the data of the pressure sensor and calculates the water depth where the pressure sensor is located to obtain the height of the sea level 7, and then the relative position of the highest waterline 8 of the hull 1 and the sea level 7 is known. By comparing the difference between the current sea level 7 liquid level and the highest waterline 8, it is determined whether the sea level 7 submerges the highest waterline 8. When the sea level 7 submerges the highest waterline 8, it is an overload state.

[0024] The controller 3 includes: A data receiving and denoising unit, used to receive data from the sensor 4 and perform denoising processing to ensure the accuracy of the data; A data processing and calculation unit, used for calculating the load information of the hull 1 based on the denoised data; The early warning judgment and alarm unit determines whether the preset maximum load is exceeded according to the calculated load information of the hull 1, and triggers an alarm signal when it is overloaded. At the same time, the alarm signal is transmitted to the land control center through the satellite terminal body 2; The path planning and weather information unit is used to receive the destination, route, and real-time weather data set by the crew, and send them to the data processing and calculation unit. At this time, the data processing and calculation unit recalculates the maximum load of the hull 1 according to the wind and wave information.

[0025] In the data processing and computing unit: When the sensor 4 is a liquid level sensor, the steps for the data processing and calculation unit to calculate the maximum load of the hull 1 are: when the liquid level of the vessel reaches or exceeds the preset maximum waterline 8; The data processing and calculation unit determines whether the sea level 7 submerges the highest waterline 8 by comparing the difference between the current sea level 7 and the highest waterline 8; When the sensor 4 is a pressure sensor, the steps for the data processing and calculation unit to calculate the maximum load of the hull 1 are: The hull 1 will be at different water depths under different load conditions through the pressure sensor. At this time, the draft of the hull 1 can be calculated by the pressure value measured by the pressure sensor; The actual load of the hull 1 is obtained according to the difference between the draft and the light load depth of the hull 1 .

[0026] In this embodiment, the controller 3 receives, processes and calculates data, and accurately calculates the load of the hull 1 in combination with the data of the sensor 4; The data receiving and denoising unit first processes the data provided by the sensor 4 to remove noise interference to ensure the accuracy of the data; the data processing and calculation unit calculates the load information of the hull 1 after denoising; the early warning judgment and alarm unit determines whether there is an overweight situation by comparing the calculation result with the set maximum load, and sends an alarm signal when overweight is found. The alarm information is sent to the land control center through the satellite terminal body 2 to ensure that the overweight problem is handled in time.

[0027] In the data processing and calculation unit, the liquid level sensor and the pressure sensor are used to determine the load condition of the hull 1 according to different working principles.

[0028] Liquid level sensor calculation steps When the liquid level sensor is working, it is installed outside the hull 1 at a position lower than the highest waterline 8. Therefore, when the sea level 7 submerges the highest waterline 8, the liquid level sensor will also be submerged. At this time, the liquid level sensor will transmit a signal to the controller 3, which is the maximum load of the hull 1. At this time, the controller 3 will sound an alarm to avoid overweight; Pressure sensor calculation steps When the sensor 4 is a pressure sensor, the step of calculating the maximum load of the hull 1 by the data processing and calculation unit is based on the draft of the hull 1 under different load conditions. The pressure sensor calculates the water depth or draft of the point through the water pressure at the location where it is located. The working principle of the pressure sensor depends on the relationship between pressure and water depth.

[0029] Specifically, the hull 1 will be at different water depths when it is unloaded and loaded. When the pressure sensor 4 is installed on the outer wall of the hull 1 and is below the sea level 7 when the hull 1 is unloaded, as the load of the hull 1 increases, the draft of the hull 1 gradually increases, and the water pressure also increases accordingly. The pressure sensor calculates the draft of the hull 1 by monitoring the pressure value. Then, the data processing and calculation unit calculates the actual load of the current hull 1 based on the difference between the unloaded depth of the hull 1 and the actually measured draft.

[0030] The relationship between pressure and water depth is Assume that the pressure measured by the pressure sensor is , the density of seawater is , the acceleration due to gravity is , then the pressure With draft The relationship between can be expressed as:

[0031] The transformation formula can be obtained:

[0032] At this time, the draft depth The draft of the hull 1 can be obtained; For example: Calculate , in meters, then the draft of hull 1 is 10 meters. If the highest waterline 8 of hull 1 is marked as 9 meters, it means that the sea level 7 submerges the highest waterline 8 by 1 meter, which means it is overloaded. If the calculation shows 8, in meters, it means that the sea level 7 is 1 meter below the highest waterline 8, which means there is no overload.

[0033] In the path planning and weather information unit, the weather data includes wind force, wind direction and wave strength. At this time, the data processing and calculation unit recalculates the maximum load of the hull 1 at this time according to the wind force, wind direction and wave strength.

[0034] In this embodiment, meteorological data is an important factor affecting the safe navigation of the ship, especially wind force, wind direction and wave strength. These meteorological data will directly affect the stability and maximum load of the ship. Therefore, the data processing and calculation unit recalculates the maximum load of the hull according to the meteorological data such as wind force, wind direction and wave strength received in real time to ensure the safe operation of the ship under different meteorological conditions.

[0035] Among them, the influence of wind The impact of wind on ships is mainly reflected in the fact that strong winds will increase the shaking of the ship, reduce the stability of the ship, and thus affect the safe load of the ship. The stronger the wind, the hull may need to reduce the load to ensure navigation stability.

[0036] In the data processing and calculation unit, the wind strength is compared with the maximum load of the hull, and the maximum load is adjusted in a certain proportion. Generally speaking, the stronger the wind, the smaller the safe load of the hull should be.

[0037] The influence of wind direction The influence of wind direction on a ship is usually manifested as the influence of wind direction on the stability of the ship. The safety of the load may be different when the ship is sailing against the wind or with the wind. If the angle between the wind direction and the heading is large, the stability of the ship will be affected to a certain extent, so the maximum load needs to be recalculated.

[0038] The data processing and calculation unit takes into account the angle between the wind direction and the vessel's heading and calculates the maximum load adjusted according to the wind direction.

[0039] The influence of wave strength The intensity of waves directly affects the stability of the hull, especially when the waves are large, the swaying amplitude of the ship increases, thereby reducing the carrying capacity of the maximum load.

[0040] The data processing and calculation unit will adjust the maximum load of the hull according to the real-time wave strength. The stronger the waves, the lower the maximum load of the hull should be.

[0041] Recalculate maximum load After receiving real-time meteorological data on wind force, wind direction and wave strength, the data processing and calculation unit will adjust the maximum load of the hull based on the following factors: Wind adjustment factor According to the strength of the wind, the system will introduce a wind adjustment coefficient , this factor will be related to the original maximum load Multiply them together to get the adjusted load.

[0042]

[0043] in, is the wind strength, is the adjusted load.

[0044] Wind direction adjustment factor Based on the angle between wind direction and ship heading, the system will calculate the wind direction adjustment coefficient , and use it in the maximum load calculation.

[0045]

[0046] in, For wind direction, The ship's heading, is the maximum load after wind force adjustment, and the maximum load after wind direction adjustment is .

[0047] Wave intensity adjustment factor The system will also To adjust the maximum load of the hull. The increase in wave strength will reduce the maximum safe load of the ship. , the maximum load will be further reduced.

[0048]

[0049] in, This is the load after adjustment for wave strength.

[0050] Finally, the data processing and calculation unit will recalculate the load adjusted for wave strength based on wind force, wind direction and wave strength. , as the current maximum safe load of the ship. Under this load, the ship can maintain the best stability and ensure navigation safety.

[0051] The controller 3 also includes a data recording and monitoring unit for recording the vessel's load data, weather conditions, route information, and alarm history in real time for subsequent analysis and supervision.

[0052] The controller 3 also includes a data recording and monitoring unit, which is mainly used to record the ship's load data, weather conditions, route information and alarm history in real time. These data are crucial for subsequent analysis and supervision. By collecting and storing this information in real time, the system can provide a detailed historical record of the ship's load and navigation status, helping regulatory authorities and crew members to understand the ship's operation in real time.

[0053] The data recording and monitoring unit can also provide multi-dimensional data query and analysis functions. For example, it can trace back and analyze historical meteorological data, load changes, and ship routes to help discover potential safety hazards and provide a basis for accident investigation. In addition, the storage of alarm history records can also support the safety management of ships and facilitate the review and processing of alarm situations.

[0054] By monitoring and analyzing these key data, the controller 3 can provide comprehensive safety protection during the ship's operation and provide decision support for managers to ensure that the ship's operation meets safety standards and that necessary adjustment measures can be taken in a timely manner. Working principle: When in use, when the sensor 4 uses a liquid level sensor, it is installed on the outer wall of the hull 1 and slightly below the highest waterline 8. At this time, when the load of the hull 1 gradually increases, the hull 1 will gradually enter the water, so the sea level 7 will gradually approach the highest waterline 8 on the hull 1. Therefore, when the sea level 7 contacts the liquid level sensor or submerges the liquid level sensor, it means that the hull 1 has reached the maximum draft depth. At this time, the signal is transmitted to the controller 3 through the communication line 5. The controller 3 can obtain the load of the hull 1 at this time and transmit the signal to the land control center through the satellite terminal body 2; When the sensor 4 uses a pressure sensor, it is placed below the sea level 7, that is, the position of the bottom of the ship, when the hull 1 is unloaded. Therefore, when the load of the hull 1 gradually increases, the hull 1 will gradually enter the water, so the sea level 7 will gradually approach the highest waterline 8 on the hull 1. At this time, the pressure sensor enters below the sea level 7 between the bottom of the ship, and the deeper the pressure sensor is below the sea level 7, the greater the water pressure it will receive. At this time, the pressure sensor transmits a signal to the controller 3. According to the data of the pressure sensor, the current depth of the pressure sensor can be calculated. By comparing the difference between the current sea level 7 liquid level and the highest waterline 8, it is determined whether the sea level 7 submerges the highest waterline 8. When the sea level 7 submerges the highest waterline 8, it means that the load of the hull 1 at this time exceeds the preset maximum load of the hull 1. Subsequently, the controller 3 generates an alarm message to remind the crew that the ship is overloaded, and the overload information is also transmitted to the land control center through the satellite terminal body 2; At the same time, the controller 3 integrates a path planning and meteorological information unit, so the crew can input the route that the hull 1 is about to take, and the unit can also receive real-time meteorological data, and the meteorological data can be fed back to the data processing and calculation unit. By combining the meteorological data to calculate the impact of wind force, wind direction and wave intensity on the hull 1 when the route is about to be taken, the current optimal load of the hull 1 is recalculated, thereby achieving the effect of risk avoidance.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
