[0049] The following will be combined with the drawings in the embodiments 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.

[0050] Before understanding the technical solution provided by the present invention, it is necessary to understand that the releaser is a device specially used in marine survey scenarios. During actual use, the releaser is first dropped into the target sea area in the ocean. Then, before the preset release time is reached, the releaser will continue to remain in standby mode and monitor the marine environmental conditions in real time. When the specified time is reached, the releaser will release the equipment and samples carried for marine survey according to a pre-programmed procedure.

[0051] refer to Figure 2-Figure 4 It can be seen that the releaser proposed in the present invention has the functions of dynamically setting the performance parameter threshold interval, constructing the survey area set, and trend prediction and adaptive adjustment. For the dynamic setting of the performance parameter threshold interval, the releaser first obtains the real-time ocean physical characteristic parameters of the target sea area and then analyzes the influence of the ocean physical characteristic parameters on the releaser performance, and finally sets the performance parameter threshold interval. For the construction of the survey interval set, it is used to prioritize the survey area according to the real-time collected ecological environment characteristic data, so as to construct a survey area set containing priority weights, so that the releaser can operate on more valuable survey areas. When the specific releaser is actually used, the ecological environment characteristic data of the target sea area is first obtained, and then the priority of each area is evaluated in combination with the performance parameter threshold interval, and finally a survey area set containing priority weights is constructed. For the trend prediction and adaptive adjustment function of the releaser, the releaser first predicts the changing trend of the ecological environment characteristic data based on time series analysis, and then sets the adaptive adjustment algorithm to dynamically adjust the performance parameter threshold interval. Finally, the power consumption constraint algorithm of the releaser is embedded, so that the releaser can optimize energy consumption and improve the overall endurance while meeting the survey needs.

[0052] Specifically, for the release method of the releaser of the present invention, refer to Figure 1 It can be seen that a technical solution is provided: a pre-programmed timed release method for marine survey, including: steps S100 to S600.

[0053] Step S100: dynamically setting the releaser's performance parameter threshold range based on the real-time ocean physical characteristic parameters of the target sea area.

[0054] In addition, it should be noted that in step S100, the performance parameters of the releaser, such as buoyancy and stability, are adjusted according to the physical characteristic parameters of the target sea area, including at least two of temperature, salinity, and flow rate, to ensure that the releaser can work stably in the target sea area and can accurately release the carried equipment or samples when the preset time is reached. It should be added that the implementation of this step S100 relies on advanced sensor technology and data processing algorithms, which can monitor and adapt to changes in the marine environment in real time.

[0055] Specifically, the method for setting the performance parameter threshold range of the releaser in step S100 includes: step S101 to step S103.

[0056] Step S101: Constructing a releaser based on a temperature gradient and salinity The correlation formula between .

[0057] It should be added that the correlation formula in step S101 is intended to determine the threshold range of the performance parameter in the releaser with respect to the threshold pressure data in the ocean.

[0058] Step S102: Solving the performance parameter threshold interval based on the joint equation .

[0059] Step S103: Set the correlation formula to .

[0060] It should be clear that for the correlation formula in step S103 and Respectively represent the calibration coefficients of the corresponding temperature and salinity in the releaser, Represents the compensation item for environmental noise in the releaser.

[0061] As a supplement to step S103, it should be clear that: The unit is ℃ / m. In actual use, the vertical temperature change rate is measured by installing a CTD sensor array outside the releaser. The unit is PSU. In actual use, it can be obtained in real time by installing a conductivity sensor outside the releaser. and The value of is obtained through the manufacturing parameters of the releaser. In this application, the specific values ​​are 0.3 and 0.2. The unit is pa, which in this application is the average value of the noise in the target ocean area, and is specifically assigned a range of ±5% in this application.

[0062] In practical applications, for the calculation of the correlation formula, it is assumed that a releaser is deployed in the target sea area. At this time, the releaser measures a temperature gradient of 0.15℃ / m and a salinity of 34.5PSU at a certain depth in the sea area. Substituting these data into the correlation formula, the result is =0.3×0.15+0.7×34.5+0.5=24.3kpa. It can be seen that when the releaser sinks to the point where the water pressure fluctuation exceeds 24.3kpa, the releaser will be triggered to take samples, thereby effectively avoiding false triggering of the releaser caused by sudden changes in temperature and salinity.

[0063] As a preferred embodiment, a supplement to step S103 is to construct a temperature gradient With flow rate It should be noted that the correlation formula is intended to determine the performance data parameter threshold in the releaser regarding the suspension depth data in the ocean.

[0064] Specifically, the performance parameter threshold interval is obtained based on the association formula ;

[0065] The correlation formula is ,in is the buoyancy correction factor, is the temperature compensation constant.

[0066] It should be noted that in this embodiment The unit is m / s. In the actual collection process, ADCP (Acoustic Doppler Velocity Surface Meter) can be installed outside the releaser for measurement. The unit is m²·s² / ℃, and in this implementation, the value is set between 0.05-0.15. The unit is ℃ / m. It is used in the associated formula to prevent the denominator from being zero. The value is 0.01. It should be added that: and In this embodiment, the value of is determined by the manufacturing parameters of the releaser and the historical environmental data and physical characteristic parameters of the target sea area.

[0067] When supplementing the above correlation formula, it must be pointed out that in practical application, assuming that the surface velocity measurement value in the target sea area is 1.2m / s and the temperature gradient is 0.08℃ / m, the correlation coefficient is and The values ​​are 0.1 and 0.01 respectively, and the results calculated according to the relevant formula are: = (0.1 × 1.2 2 ) / (0.08+0.01)=1.8m. It can be seen from this that when the releaser reaches a depth of 1.8m in the sea area, it is least affected by the surrounding water flow, so the releaser will remain suspended at this depth, thus effectively avoiding the releaser instability or false triggering caused by excessive flow rate.

[0068] As a preferred embodiment, as another supplement to step S103, constructing salinity With flow rate The combined formula is designed to determine the threshold interval of performance parameters in the releaser with respect to the flow velocity variation data in the ocean.

[0069] The performance parameter threshold interval is obtained based on the joint formula .

[0070] The combined formula is ,in is the salinity-velocity coupling coefficient, The reference salinity is determined based on the historical average salinity of the target sea area. is the flow rate nonlinear correction factor, which is used to compensate for the sensitivity of the releaser at low flow rates. It is the minimum flow rate threshold, used to prevent the releaser from being disturbed by zero flow rate.

[0071] It should be noted that The unit is Pa·s² / PSU, which is calibrated by experiment (value range 0.1-0.5). Usually the historical average value of the sea area is taken. The unit is Pa, The unit is m / s.

[0072] It is necessary to supplement the joint formula that when the real-time measured salinity in the sea area is 36.2PSU and the flow velocity is 0.8m / s, The value is set to 0.3. The value is set to 35. The value is 0.5. When the value is 0.05, it is substituted into the joint formula:

[0073]

[0074] = .

[0075] Therefore, it can be seen that when the pressure sensor in the releaser detects that the ambient pressure fluctuation exceeds 2.3 kPa, the releaser triggers sampling to avoid missing transient events caused by the superposition of salinity fronts and strong currents.

[0076] In addition, it should be added that the various parameters in the joint formula are obtained through a combination of statistical analysis of historical data of the marine environment of the target sea area and laboratory simulation experiments. First, the historical salinity and flow rate data of the target sea area are collected and statistically analyzed to obtain the reference salinity value. Secondly, under laboratory conditions, the releaser response in different salinity and flow rate environments is simulated, and the value range of the salinity-flow rate coupling coefficient and the flow rate nonlinear correction factor is determined through calibration experiments. Finally, according to the real-time salinity and flow rate data in the actual marine environment, as well as the preset minimum flow rate threshold, these parameters are substituted into the joint formula for calculation, thereby realizing precise pre-programmed timing control of the releaser.

[0077] Step S200: constructing a survey area set including priority weights based on the ecological environment characteristic data and performance parameter threshold ranges of the target sea area.

[0078] It should be clear that step S200 in the present invention is used to construct a priority evaluation system to guide the survey operation of the releaser in the target sea area. Through the comprehensive analysis of the ecological environment characteristic data, ecologically sensitive areas or potential pollution sources can be identified, and then these areas can be assigned higher priorities.

[0079] Specifically, the ecological environment characteristic data include the intensity of biological aggregation , Chemical Concentration Gradient and the diffusion pathways of pollutants , the priority in the survey area set is positively correlated with any item in the ecological environment characteristic data;

[0080] The method for constructing a survey area set including priority weights includes: establishing a priority ranking formula, wherein the priority ranking formula is used to output the area priority weights .

[0081] The priority ranking formula is: ,in are the dynamic adjustment coefficients corresponding to the items in the ecological environment characteristic data, Used to represent the modulus of chemical substance concentration gradient, It is used to indicate the matching degree of pollutant diffusion path, and its value ranges from (0-1).

[0082] It should be added that The bioaccumulation intensity (unit: ind / m³) is obtained by installing a hydrophone outside the releaser to measure the acoustic reflection signal intensity. Unit: mg / L / m, Through the Lagrangian particle tracking model calculation within existing computer technology, is a dynamic weight coefficient that satisfies the setting that the sum is 1.

[0083] Specifically, for the use of the priority ranking formula in actual operation, for example, in a sea area, when a certain area is detected =85dB, =0.5mg / L / m, =0.8, set λ1=0.4 (biological priority), λ2=0.3, λ3=0.3, then

[0084] = , so it can be seen that the sea area is marked as high priority (threshold>30), triggering the sampling of the releaser.

[0085] Step S300: Based on time series analysis, trend prediction is performed on changes in ecological environment characteristic data in different survey areas within the same sea area, and an adaptive adjustment algorithm is set.

[0086] It should be clear that in the present application, step S300 is used to dynamically adjust the sampling frequency of the releaser according to the results of the time series analysis to adapt to the real-time changes in the ecological environment characteristic data in different survey areas.

[0087] Specifically, the adaptive algorithm set based on ecological environment characteristic data in this application is ,in is the final predicted value, The basic prediction value is calculated based on the average value of historical ecological environment characteristic data. The path correction amount is positively correlated with the pollutant diffusion rate.

[0088] It should be pointed out that in practical applications, the adaptive algorithm assumes that within the target sea area, The pollutant concentration indicated rises by 20% after 24 hours. The value of is 0.9, The value of is 0.3. From this, we can infer that equal , equal .

[0089] Step S400: The closed-loop feedback controller on the releaser dynamically adjusts the value of the performance parameter threshold interval according to the adaptive adjustment algorithm, and embeds the power consumption constraint algorithm of the releaser in the adjustment process.

[0090] It should be clear that in the present application, step S400 is used to use a closed-loop feedback controller to monitor the operating status of the releaser and changes in the surrounding environment in real time, so as to achieve accurate regulation of the performance parameter threshold range.

[0091] In addition, the power consumption constraint algorithm in step S400 is specifically as follows: ,in is the regional priority weight, is the total energy of the releaser, is the residual energy of the releaser, is the remaining usage time of the releaser, is the endurance coefficient, It is used to indicate the influence of the current energy status on the endurance time. When the remaining energy is large, Close to 1, at this time, energy consumption allocation takes more ecological value into consideration. When the remaining energy is insufficient, As it approaches 0, it tends to distribute the remaining energy evenly to ensure that the releaser does not run out of power prematurely. The decay constant used to represent the power consumption of the releaser is determined based on the properties of the releaser.

[0092] It should be noted that The unit is Wh, The unit is hours, for and Any item in the value.

[0093] It should be pointed out that in practical applications, for the power consumption limitation algorithm, assuming that the initial energy of the releaser in the target sea area is 1000Wh, it must be ensured that the releaser can work continuously for 720 hours. Under this condition, the weight distribution of the three different areas in the target sea area is W1=93, W2=65 and W3=28 respectively.

[0094] At this time, the corresponding ;

[0095] When the remaining energy 400Wh, remaining time When it is 360h, , at this time, the energy consumption of the releaser is redistributed, that is:

[0096] ;

[0097] Afterwards, the degradation factor is calculated It can be seen that when the releaser maintains operation and the detection of the W3 area is turned off, 153.3Wh of energy consumption can be saved.

[0098] In addition, it is necessary to supplement the above endurance coefficient that when the high Value (sufficient energy): Focuses on ecological weight, allowing high energy consumption to obtain data, low Value (lack of energy): Sacrifice some data quality to ensure that the device continues to run until the task is completed. Combined with the above content, it can be seen that due to The value of is between 0 and 1. A value of 0.37 indicates insufficient energy. At this time, the releaser should give priority to monitoring the W1 and W2 areas and reduce the energy consumption in the W3 area to ensure the smooth completion of the overall task. At the same time, according to the real-time remaining energy and time conditions, the energy consumption allocation of each area is dynamically adjusted to ensure that as much valid data as possible is obtained under limited energy.

[0099] Step S500: The releaser selects a survey area that meets the releaser working conditions from the survey area set according to the change of the performance parameter threshold range.

[0100] It should be clear that step S500 is used in the present invention for real-time adjustment based on the performance parameter threshold range to ensure that the releaser can work under optimal environmental conditions, thereby improving the accuracy and reliability of data collection.

[0101] Step S600: combining the selected releaser survey area with the dynamic threshold interval, calculating the operating parameters of the releaser, so that the survey operation of the releaser can be adjusted according to the real-time changes of the target ocean.

[0102] It should be clear that in the present invention, the releaser operating parameters include: trigger time and sinking depth. Combined with the selected releaser survey area and the dynamic threshold interval, the formula for calculating the releaser operating parameters includes: a calculation formula based on the trigger time and a calculation formula based on the sinking depth.

[0103] Specifically, the calculation formula based on the trigger time is: ;

[0104] The calculation formula based on the sinking depth is: .

[0105] It should be added that for the calculation formula based on the trigger time, is the basic trigger interval of the releaser, The priority weight for the selected releaser survey area, is the performance parameter threshold interval, It is the average noise value that the releaser can release.

[0106] As a preferred implementation, when the calculation formula based on the trigger time is actually put into use, the selected area =85, current =0.8KPa, 0.1kpa;

[0107] at this time ;

[0108] therefore , so the trigger time of the operating parameters of the releaser in this embodiment is 0.01 minutes.

[0109] As a preferred embodiment, when the calculation formula based on the sinking depth is actually used, hour, = , = ,at this time =0.6+0.0022=0.6022m, so it can be known that the triggering depth of the operating parameters of the releaser in this embodiment is 0.6022m.

[0110] As a preferred implementation method, refer to Figure 5 It can be seen that the present invention also proposes a pre-programmed timed releaser for ocean survey. It should be supplemented that the pre-programmed timed releaser for ocean survey uses the above-disclosed pre-programmed timed release method for ocean survey and includes:

[0111] The sensor array module is used to collect ocean physical characteristic parameters and ocean ecological parameter data in real time.

[0112] The edge computing unit is used to process the data collected by the sensor array module and execute the performance parameter threshold interval, priority ranking formula, adaptive adjustment algorithm, power consumption constraint algorithm and operation parameter calculation formula of the set releaser.

[0113] The adaptive control module is used to adjust the operating parameters of the releaser according to the dynamically adjusted performance parameter threshold interval and priority weight.

[0114] The data storage unit is used to store the ocean physical characteristic parameters, ocean ecological parameter data collected by the sensor array module, and the data processed by the edge computing unit.

[0115] The power management module is used to manage the energy supply of the releaser and optimize the energy consumption allocation according to the power consumption constraint algorithm.

[0116] The communication module is used to realize data transmission between the releaser and the remote monitoring center, upload survey data and receive remote control instructions.

[0117] It should be noted that, in this embodiment, the sensor array module is installed on the outside, bottom and side wings of the releaser's shell, and includes temperature sensors, salinity sensors, flow rate sensors and pressure sensors, which can monitor marine environmental parameters in real time in all directions. The edge computing unit is installed in the core area inside the waterproof and sealed cabin of the releaser, the adaptive control module is installed in the core control cabin and is adjacent to the edge computing unit, the data storage unit is installed in the storage cabin of the releaser, and the power management module and the communication module are installed in the power cabin and the communication cabin respectively to ensure that the functions of each module operate normally and do not interfere with each other.
