In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or a specific connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0043] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1-Figure 4 , the detection method based on the ship turbulence height in the embodiment of the present invention comprises:

[0044] 101. Real-time sensing of the gravity acceleration of each detection position of the ship at the current moment;

[0045] In this embodiment, gravity sensors are provided at designated positions of the ship for sensing the gravity acceleration of the ship at the current moment in real time. The gravity sensor is made of a cantilevered displacer made of an elastic sensitive element, and an energy storage spring made of an elastic sensitive element is used to drive the electric contact to complete the conversion from gravity change to electrical signal, thereby obtaining the gravity acceleration value of the current environment. When the ship is bumpy, the bumping amplitude of each position of the bow, hull and stern may be different, so it is necessary to install a gravity sensor perpendicular to the hull at these three locations, and each sensor ensures that the z-axis is upward and perpendicular to the hull.

[0046] 102. Calculate the difference value of each detection position of the ship according to each gravity acceleration sensed in real time and the environmental gravity acceleration of the current environment;

[0047] In this embodiment, the positive or negative value of the difference value is taken as the floating or diving state of the ship in the current waves, and the difference value output is an absolute value, and the difference value changes according to the sensed change in the gravity acceleration of the ship.

[0048] 103. According to these difference values ​​and the directions of these difference values, it is determined whether the ship is at the crest or trough of the wave;

[0049] In this embodiment, since the detection of the ups and downs of the ship on the waves is carried out through real-time detection by the gravity sensor, the gravity changes sensed at each moment are judged. For example, when the ship is in the stage of floating up to the crest on the waves, the gravity sensor senses a gravity acceleration greater than the ambient gravity acceleration, and is in an overweight state. The difference value taken here is a positive value. When the ship is in a downrush state, the gravity sensor senses a gravity acceleration less than the ambient gravity acceleration, and is in a weightless state. The difference value taken here is a negative value. To determine whether the ship is at the crest or trough of the wave, it is necessary to judge the continuous state of the ship before this. If it is a continuous overweight state and is transferred to a weightless state, then the ship was at the crest of the wave at the previous moment. Conversely, if it is a continuous weightless state and is transferred to an overweight state, then the ship was at the trough of the wave at the previous moment.

[0050] Furthermore, step 103 may further specifically execute:

[0051] 1031. Determine whether the absolute value of the difference value is less than a preset decay threshold;

[0052] If it is less than the decay threshold, the gravity acceleration of each detection position of the ship at the next moment is sensed again in real time to update the difference value;

[0053] 1032. If it is not less than the decay threshold, determine whether there is a continuous change in the direction of the updated difference value compared to the previous difference value;

[0054] 1033. If there is a continuous change, it is determined that the ship is at the crest or trough of the wave;

[0055] If there is no continuous change, the gravity acceleration of each detection position of the ship at the next moment is sensed again in real time to update the difference value.

[0056] Specifically, there is an acceleration decay process when the ship floats up to the wave crest and rushes down to the wave trough. In the present embodiment, a decay threshold is assumed by utilizing this acceleration decay process. The value of this decay threshold is adjusted according to the user or the actual application scenario. If the difference value is greater than the decay threshold and the direction changes continuously, it means that the ship is switching between an overweight state and a weightless state at this moment. This can determine the current position of the ship at the wave crest or trough for subsequent calculation of the turbulence height.

[0057] 104. Based on a preset pitch height algorithm, the average value of the height of each detection position of the ship at the crest or trough of the wave is calculated to obtain a total pitch height.

[0058] In this embodiment, since the overall structure of the ship is a long strip, the gravity acceleration sensed by the gravity sensors thereon also has certain slight differences. In order to improve the accuracy of the calculation of the turbulence height, a large amount of these data are collected and the average value is removed to obtain an accurate value.

[0059] Furthermore, step 104 may further specifically execute:

[0060] 1041. Based on a preset turbulence height algorithm, calculate the height of the wave crest or trough at each detection position of the ship in each time period, and obtain the turbulence height at each detection position of the ship corresponding to the moment;

[0061] 1042. Determine whether the directions of the difference values ​​of at least two adjacent time periods at each detection position of the ship are in the same direction under these time periods;

[0062] 1043. If it exists, the pitch heights of each detection position of the ship in these time periods are accumulated and the average value is calculated to obtain the total pitch height, and the gravity acceleration of each detection position of the ship at the next moment is sensed in real time to update the difference value;

[0063] If it does not exist, the gravity acceleration of each detection position of the ship at the next moment is directly sensed again in real time to update the difference value.

[0064] In this embodiment, the calculation formula of the momentary turbulence height is:

[0065] Vn=Vn-1+Gn*t;

[0066] Sn=1 / 2*(Vn-1+Vn)*t=1 / 2*(Vn-1+Vn-1+(Gn-g)*t)*t;

[0067] Among them, Vn is the current speed of the ship, Vn-1 is the speed of the ship at the last moment, Sn is the distance (i.e., the bump height), t is the sampling interval of the gravity sensor, Gn is the gravity acceleration sensed by the gravity sensor, and g is the gravity acceleration of the earth.

[0068] Specifically, the gravity acceleration of each detection position of the ship at the current moment is sensed in real time, and the difference values ​​of each detection position of the ship are calculated according to each gravity acceleration sensed in real time and the ambient gravity acceleration of the current environment. According to these difference values ​​and the directions of these difference values, it is determined whether the ship is at the crest or trough of the wave. Based on the preset turbulence height algorithm, the average value of the height of each detection position of the ship at the crest or trough of the wave is calculated to obtain the total turbulence height, thereby realizing the sensing of the ship's turbulence and accurately measuring the turbulence height, thereby improving the accuracy of ship warning.

[0069] The above describes the detection method based on the ship pitch height in the embodiment of the present invention. The following describes the detection system based on the ship pitch height in the embodiment of the present invention. Figure 3 , the detection system based on ship turbulence height comprises:

[0072] A position determination module 203 is used to determine whether the ship is at a crest or trough of the wave according to the difference values ​​and the directions of the difference values;

[0073] The pitch height calculation module 204 is used to calculate the average value of the height of each detection position of the ship at the crest or trough of the wave based on a preset pitch height algorithm to obtain the total pitch height.

[0074] Specifically, the gravity acceleration of each detection position of the ship at the current moment is sensed in real time, and the difference values ​​of each detection position of the ship are calculated according to each gravity acceleration sensed in real time and the ambient gravity acceleration of the current environment. According to these difference values ​​and the directions of these difference values, it is determined whether the ship is at the crest or trough of the wave. Based on the preset turbulence height algorithm, the average value of the height of each detection position of the ship at the crest or trough of the wave is calculated to obtain the total turbulence height, thereby realizing the sensing of the ship's turbulence and accurately measuring the turbulence height, thereby improving the accuracy of ship warning.

[0075] Among them, gravity sensors are installed at designated positions of the ship to sense the gravity acceleration of the ship at the current moment in real time.

[0076] The positive or negative value of the difference is taken as the floating or sinking state of the ship in the current waves, and the difference value output is the absolute value.

[0077] The difference value varies according to the sensed gravitational acceleration of the ship.

[0078] The location determination module 203 may also be specifically used for:

[0079] Determine whether the absolute value of the difference value is less than a preset decay threshold;

[0080] If it is less than the decay threshold, the gravity acceleration of each detection position of the ship at the next moment is sensed again in real time to update the difference value;

[0081] If it is not less than the decay threshold, determining whether there is a continuous change in the direction of the updated difference value compared to the previous difference value;

[0082] If there is a continuous change, it is determined whether the ship is at the crest or trough of the wave;

[0083] If there is no continuous change, the gravity acceleration of each detection position of the ship at the next moment is sensed again in real time to update the difference value.

[0084] The bump height calculation module 204 may also be specifically used for:

[0085] Based on the preset turbulence height algorithm, the height of the wave crest or trough at each detection position of the ship in each time period is calculated to obtain the turbulence height at each detection position of the ship at the time corresponding to the detection position;

[0086] Determine whether the directions of the difference values ​​of at least two adjacent time periods at each detection position of the ship are in the same direction under these time periods;

[0087] If it exists, the turbulence heights at these time periods are accumulated to obtain the total turbulence height;

[0088] If it does not exist, the gravity acceleration of each detection position of the ship at the next moment is sensed again in real time to update the difference value.
