It should be noted that... Figure 1 This is only one instance of a specific particular instance, and is intended to illustrate the types of components that may exist in the aforementioned computing devices.

[0030] Under the above operating environment, according to the first aspect of this embodiment, a method for processing marine environmental data is provided. Figure 2 A flowchart illustrating the method is shown below. (Refer to...) Figure 2 As shown, the method includes:

[0031] S202: Receive marine environmental data from a marine environmental data acquisition device, wherein the marine environmental data acquisition device includes a first data acquisition device disposed on the port side of the carrier and a second data acquisition device disposed on the starboard side, and wherein the marine environmental data includes first marine environmental data acquired by the first data acquisition device and second marine environmental data acquired by the second data acquisition device.

[0032] S204: Determine the first valid marine environment data of the first marine environment data based on the first attitude information at the same time, and determine the second valid marine environment data of the second marine environment data based on the second attitude information at the same time, wherein the first attitude information is collected by the first attitude sensor in the first data acquisition device, and the second attitude information is collected by the second attitude sensor in the second data acquisition device.

[0033] S206: Based on the first and second valid marine environmental data, determine the sea surface wind direction, and determine the true value of the marine environmental data based on the sea surface wind direction; and

[0034] S208: By using a pre-defined method, outliers in the true values ​​of marine environmental data are removed, and marine environmental data information is output.

[0035] As described in the background section, marine meteorological data is often collected via satellites and buoys. Satellite data has low accuracy, while buoys suffer from short lifespans and limited coverage areas. Data acquisition via shipborne sensors presents several technical challenges, including: 1. Shipborne anemometers collect composite wind data, which can deviate significantly from actual data when the ship is in motion; 2. The ship's rolling and pitching motions can render sensor data unusable, especially in high sea states where anemometer errors may exceed equipment limits; 3. The heat island effect of ships can pollute the marine environment, leading to significant discrepancies between sensor data and actual data.

[0036] In view of this, embodiments of this application provide a method for processing marine environmental data, wherein reference is made to Figure 3 The diagram illustrates a marine environmental data acquisition device that receives marine environmental data simultaneously from the port and starboard sides of the carrier. The data acquisition time can be preset, for example, data is collected every 10 seconds. A first data acquisition device and a second data acquisition device are integrated into the marine environmental data acquisition system.

[0037] Furthermore, the computing device determines the first valid marine environmental data of the first marine environmental data based on the first attitude information at the same time, and determines the second valid marine environmental data of the second marine environmental data based on the second attitude information at the same time. The first and second attitude information refer to the attitude information of the port and starboard sides of the carrier, thereby determining the carrier's roll angle. The computing device can determine whether to extract data at that moment based on the carrier's roll angle.

[0038] Furthermore, the computing device determines the sea surface wind direction based on the first and second valid marine environmental data, and then determines the true value of the marine environmental data based on the sea surface wind direction. For example, by using the sea surface wind direction, it can be determined whether the data collected by the port-side equipment or the starboard-side equipment is more accurate, thus selecting the more accurate data at the same time as the true value of the marine environmental data.

[0039] Furthermore, the computing device uses a pre-set method to remove outliers from the true marine environmental data, outputting marine environmental data information. Through this method, the computing device can eliminate outliers, thereby obtaining more accurate marine environmental data information.

[0040] This method acquires marine environmental data from a specific installation location, and then uses a first attitude sensor and a second attitude sensor for initial data correction. The true marine environmental data at the same moment is then determined using data from both sides, and outliers are removed to obtain more accurate marine environmental data. This solves the technical problem in existing marine environmental data processing methods where the accuracy of the data cannot be determined, leading to errors in the acquired data; currently, no effective solution has been proposed for this issue.

[0041] also, Figure 3 A schematic diagram of a marine environmental data acquisition system is shown. (Refer to...) Figure 3 As shown, the integrated environmental data acquisition unit is installed on both the port and starboard sides. The 0° markers on both sides of the weather instruments point towards the bow and are parallel to the ship's centerline. Each unit is equipped with two infrared temperature sensors, facing outwards. One sensor measures sea surface temperature at a 60° angle downwards to the horizon, and the other measures sky temperature at a 60° angle upwards to the horizon. A control circuit board is installed in the control box, which interacts with the various sensors, sending measurement commands and receiving measurement data. The meteorological parameter acquisition rate is 1 time per second. The data acquired per second is transmitted via an RS422 data cable to computing equipment in the ship's cabin, such as an evaporative waveguide diagnostic host.

[0042] In addition, integrated environmental data acquisition devices mounted on both the port and starboard sides simultaneously collect marine environmental data, including wind speed, wind direction, air pressure, humidity, air temperature, sky temperature, and sea surface temperature, and send the collected data to the central processing unit. The central processing unit also receives parameters such as speed, heading, bow, pitch angle, and roll angle from the ship's navigation system and auxiliary equipment, and fuses them with data from attitude sensors. Based on the platform's attitude, it removes inaccurate data measured under large pitch and roll conditions, and based on the instantaneous wind direction, it identifies and eliminates data contaminated by the ship's heat island effect. By fusing hydrological and meteorological parameters from both the port and starboard sides, it calculates the true wind speed, true wind direction, and temperature, humidity, air pressure, and sea surface temperature that reflect the true ocean conditions.

[0043] In addition, the marine environmental data acquisition system consists of an anemometer, a temperature and humidity meter, an infrared thermometer, a barometric pressure sensor, an attitude sensor, and an acquisition and control module. The anemometer measures the relative wind speed and direction at the sea surface; the temperature and humidity meter measures the air temperature and relative humidity at the equipment's altitude; the infrared thermometer includes a sea surface infrared thermometer and a sky infrared thermometer, with the sky infrared thermometer measuring sky temperature to correct for sea surface temperature; the barometric pressure sensor measures the atmospheric pressure at the equipment's altitude; and the attitude sensor is a backup function, used to measure the ship's pitch and roll angles when the ship cannot transmit pitch and roll information. The barometric pressure sensor, attitude sensor, and acquisition and control module are integrated into a sealed metal box.

[0044] Optionally, the operation of determining the first valid marine environmental data of the first marine environmental data based on the first attitude information at the same time, and determining the second valid marine environmental data of the second marine environmental data based on the second attitude information at the same time, includes: determining whether the first attitude information at each time is within a preset angle range; if the first attitude information is not within the preset angle range, removing the first marine environmental data at the current time to determine the first valid marine environmental data; and determining whether the second attitude information at each time is within a preset angle range; if the second attitude information is not within the preset angle range, removing the second marine environmental data at the current time to determine the second valid marine environmental data.

[0045] Specifically, for example, when the tilt angle of the carrier is greater than 15°, the error between the wind speed sensor measurement and the true value is greater than the required accuracy. Therefore, when determining the current pitch and roll angle of the ship, if the pitch and roll angle is detected to be greater than 10° (less than 15° to ensure accuracy), the measurement data at that moment is discarded and not included in subsequent calculations.

[0046] Optionally, the sea surface wind direction includes a first sea surface wind direction and a second sea surface wind direction. The operation of determining the sea surface wind direction based on the first effective marine environmental data and the second effective marine environmental data, and determining the true value of the marine environmental data based on the sea surface wind direction, includes: determining the first sea surface wind direction based on the first effective marine environmental data; determining the second sea surface wind direction based on the second effective marine environmental data; selecting the first effective marine environmental data at the current moment as the true value of the marine environmental data when the first sea surface wind direction meets the preset conditions; and selecting the second effective marine environmental data at the current moment as the true value of the marine environmental data when the second sea surface wind direction meets the preset conditions.

[0047] Specifically, for example, the relative wind directions on the port and starboard sides at the same moment can be compared: if the wind directions differ significantly, it is considered to be a gust or vortex wind, and it is impossible to determine which measurement value on the port and starboard sides is the required value. The data at this moment is discarded and not included in subsequent calculations; if the wind directions are basically the same, it is considered to be a steady wind.

[0048] Under calm wind conditions, determine which sensor reading is more reasonable on either the port or starboard side. The principle is to prioritize the sensor readings taken from the path the wind travels from the sea surface, passing over the sensor before crossing the ship's hull. This is because if the wind passes over the hull first, the hull, being a large hot body, will inevitably contaminate the temperature and humidity changes brought by the wind, resulting in contaminated sensor readings.

[0049] For example, firstly, it is determined whether the wind obtained by the port and starboard data acquisition devices is blowing from the port side (port wind) or the starboard side (starboard wind). Only when both sides are in the same direction and the angle error is within a certain range, is the measurement data considered valid. Among the valid data, the data from which acquisition device is retained is determined according to the relative wind direction. When it is determined to be port wind, the port air temperature and relative humidity are retained; when it is determined to be starboard wind, the starboard air temperature and relative humidity are retained.

[0050] Therefore, by using the above methods, we can determine the true value of marine environmental data that is closer to the marine environment at the same time.

[0051] Optionally, the true value of the marine environmental data is an ordered sequence of data sorted by time, and the operation of removing outliers from the true value of the marine environmental data and outputting marine environmental data information by means of a pre-set method includes: calculating the slope determined by two adjacent data in the true value of the marine environmental data; and removing the data when the slope exceeds a pre-set threshold and outputting marine environmental data information.

[0052] Specifically, when ships are navigating at sea, there are many uncertainties in measuring environmental parameters. For example, gusts of wind, vortex winds, sunlight reflected from the sea surface, and even airflow and pressure changes caused by artillery fire can all affect the accuracy of the measurements. In order to eliminate or reduce the impact of these uncertainties on environmental parameter measurements, appropriate algorithms need to be used in the signal processing module to determine the validity of data and remove outliers.

[0053] For example, suppose the interval for collecting marine environmental data is T seconds, and the collected marine environmental data points are {Y(n), n=0,1,2,3,……,N-1}.

[0054] After storing the collected data sequence, calculate the slope determined by the two points sequentially:

[0055]

[0056] Compare each slope to a threshold, and mark the slopes that exceed the threshold:

[0057] G(n)≥|G T |

[0058] Among them G T It's a threshold.

[0059] Remove all points that cause the slope to exceed the threshold, and average the remaining points.

[0060]

[0061] M represents the total number of remaining points.

[0062] In this way, data points with large errors in the true value of marine environmental data are removed, thus obtaining marine environmental data information.

[0063] In addition, refer to Figure 1 As shown, according to a second aspect of this embodiment, a storage medium is provided. The storage medium includes a stored program, wherein, when the program is executed, a processor performs any of the methods described above.

[0064] Therefore, according to this embodiment, marine environmental data is acquired from a specific installation location, and then preliminary data correction is performed using a first attitude sensor and a second attitude sensor. Then, the true value of the marine environmental data at the same moment is determined using data from both sides, and outliers are removed, thereby obtaining more realistic marine environmental data information. This solves the technical problem in existing marine environmental data processing methods where the accuracy of the data cannot be determined, leading to errors in the acquired data information; currently, no effective solution has been proposed for this problem.

[0065] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, because according to the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions and modules involved are not necessarily essential to the present invention.

[0066] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.
