[0043] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. 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.

[0044] A method for evaluating the severity of a launch platform's coastal service environment according to an embodiment of the present invention is as follows: Figure 1 As shown. Figure 1 In this embodiment, the present invention includes:

[0045] Step 100: Conduct on-site testing of the corrosion environment of the launch platform to obtain objective data of the platform.

[0046] In view of the corrosive environment formed by the marine salt spray atmosphere where the launch platform is located, the physical and chemical signals and signal values ​​corresponding to the various contributing factors of the corrosive environment are continuously detected. The corresponding signal sensors are arranged according to the type of physical and chemical signals. According to the scale of the launch platform, the physical and chemical signals and signal values ​​of key points and evenly distributed points are continuously detected. Continuous detection is time-series, and the detection cycle of each signal sensor is affected by the type of contributing factors and has a clear time-series interval. Through on-site detection of the corrosive environment, objective data of the platform environment in real time and increment is formed.

[0047] Step 200: Form a corrosion environment simulation of the launch platform based on the objective data of the platform.

[0048] Those skilled in the art can understand that formulating empirical data and empirical laws in a certain field can form a data simulation model for the corresponding field, which can basically correctly reflect the characteristics and status of the field. By giving reasonable input data, a simulation process and simulation results that meet the expectations of the physical entity can be obtained. The corrosion environment can be simulated by forming a corresponding data processing simulation model based on the causes of corrosion in the corrosion environment, the independent / correlated laws of corrosion factors and empirical data. By inputting the field data of the launch platform, the corrosion simulation process can be deduced using the corrosion environment simulated by the corrosion simulation model. According to the contributing factors of the corrosion environment and the corresponding field data, the models that constitute the corrosion environment simulation process include but are not limited to flow field simulation, temperature field simulation, humidity field simulation, condensation simulation and corrosion quantification simulation.

[0049] Step 300: Use the platform's objective data to calibrate the corrosion environment simulation process, and evaluate the severity of the environment through corrosion environment simulation.

[0050] Through corrosion environment simulation, a discrete evaluation of the severe conditions of metal corrosion in the environment of the launch platform is formed, and the corrosion environment simulation results are verified by comparing the discrete evaluation results with the corresponding characteristics quantified by the platform's objective data. The verification results and the immediacy of the platform's objective data are further used to form an iterative optimization of the corrosion environment simulation process. Finally, the overall environmental severe conditions are evaluated based on the corrosion environment simulation output.

[0051] The method for evaluating the severity of the coastal service environment of a launch platform in an embodiment of the present invention is based on the test results of multiple types of parameters of surface corrosion of the service launch platform, and is modeled and simulated in combination with the corrosion environment factors and corrosion laws of key structures. The common data simulation technology in the prior art is used to fit the laws of the corrosion mechanism of the launch platform under the corrosive environment, to form a quantitative analysis and prediction of the corrosion damage behavior under the corrosive atmospheric environment, and to quantitatively reveal the degree of corrosion damage.

[0052] The data flow of the method for evaluating the severity of the coastal service environment of a launch platform according to an embodiment of the present invention is as follows: Figure 2 As shown. Combined Figure 1 As shown, step 100 includes:

[0053] Step 110: Determine the distributed deployment locations of various types of sensors on the launch platform based on the sensor characteristics.

[0054] The distributed deployment locations are determined based on the signal characteristics, installation characteristics, and signal acquisition coverage integrity requirements of the type of sensors. For example, sensors for measuring surface temperature and humidity are deployed in different directions and at different heights of the launch platform, covering the outline of the launch platform; sensors for the wetting time (TOW) test are deployed at the connection between the beams outside the platform and at obstructed locations outside the platform; sensors for measuring surface salt deposition concentration are deployed on the surface of the launch platform in different directions and directions; sensors for testing the pH value of the surface liquid film are deployed on the surface of the launch platform in different directions and directions; sensors for local wind speed testing are deployed in different directions around the launch platform, below the launch platform, and above the launch platform; sensors for corrosion rate testing are deployed at locations with significant corrosion and locations with subtle corrosion.

[0055] In one embodiment of the present invention, the sensor for measuring the surface temperature and humidity adopts a collection probe of a portable surface temperature and humidity meter and a grid-type temperature and humidity transmitter placed at the test position to collect the temperature and humidity data of the platform, wherein the portable surface temperature and humidity meter measures the surface temperature of the launch platform at the current position at the current moment and the ambient temperature and humidity near the surface, or a grid-type temperature and humidity transmitter can be used to continuously monitor the ambient temperature and humidity of the test position, and the data is automatically stored in the sensor;

[0056] The sensor for the wetting time (TOW) test uses interdigital electrodes, and uses a computer and an acquisition card to collect voltage, current, and resistance data. The basic principle is that when a stable liquid film is formed on the interdigital electrodes, it changes from being open to being conductive, and the electrical signals at both ends will change significantly. The time of change is considered to be the time when the interdigital electrodes are wetted.

[0057] The sensor for measuring surface salt deposition concentration uses a salt patch, which is attached to the test surface, and the amount of air inside is reduced as much as possible. Then, 3 ml of deionized water is extracted with a syringe. At the edge of the salt patch, the syringe is inserted into the test site at a 30° angle, so that it penetrates the foam and enters the test chamber formed by the test surface and the rubber membrane. 1.5 ml of deionized water is injected, and the needle is gently adjusted to expel the air in the salt patch. The syringe is taken out, and the needle is pointed upward to gently push out the air inside. Then, the syringe is reinserted into the salt patch, and the remaining deionized water is injected into the salt patch. Do not move the syringe. Finally, extract and recover as much solution as possible, and inject the solution sample directly into the conductivity test chamber for testing, and record the salt deposition concentration on the surface of the transmitter;;

[0058] The sensor for testing the pH value of the surface liquid film uses the solution after the surface salt deposition measurement to wet the pH test paper, quickly calibrate it with the standard colorimetric card, and read the surface pH value;

[0059] The sensor for the local wind speed test uses a portable anemometer held on the windward side to measure the wind speed around the launch platform and manually record the data at different locations;

[0060] The sensor for the corrosion rate test places electrodes at the test position and uses a coupled multi-electrode array corrosion sensor system to collect the corrosion rate.

[0061] Step 120: Determine the signal acquisition frequency of each type of sensor in combination with the sensor characteristics.

[0062] In one embodiment of the present invention, the surface temperature and humidity measurements cover typical times of the day, such as morning, noon and evening; the wet time (TOW) test is continuously tested for at least 24 hours; the surface salt deposition concentration test is repeated at least 4 times with a cycle of 10 minutes each time; the surface liquid film pH value test is performed at the same frequency as the surface salt deposition concentration test; the local wind speed test is carried out continuously; and the corrosion rate test is carried out regularly.

[0063] Step 130: Perform data fusion on the collected signals of various types of sensors to form incrementally updated platform objective data.

[0064] Data fusion includes but is not limited to the normalization of the format of collected data, data time series tagging and data incremental storage. The objective data of the platform after data fusion includes single type information data and composite type information data formed by preset fusion rules.

[0065] The method for evaluating the severity level of the coastal service environment of a launch platform in an embodiment of the present invention collects on-site environmental signals to form correlated data that characterizes the characteristics of various dimensions in the environment in which the launch platform is located, and is synchronized in time series, thereby forming a full multi-dimensional feedback of the on-site environmental information.

[0066] like Figure 1 In one embodiment of the present invention, Figure 2 As shown, step 200 includes:

[0067] Step 210: Utilize the meteorological data and the air flow data in the platform objective data to form the overall flow field simulation process of the launch platform.

[0068] Meteorological data include launch site atmospheric environment data obtained from the National Meteorological Science Data Center. Through statistical analysis of meteorological data, an all-day atmospheric environment alternating spectrum of typical temperature, humidity, wind direction, wind force and other environments of the launch site environment in four seasons is formed, providing input state data for the macroscopic atmospheric environment simulation of the full-scale launch platform. The air flow data in the platform's objective data provides input state data for the microscopic atmospheric environment simulation of the full-scale launch platform. According to the basic principles of atmospheric flow and aerodynamic laws combined with existing experimental research results, as well as accumulated meteorological data and air flow data, a reasonable launch platform overall flow field simulation process is established to reflect the macroscopic and microscopic dynamic processes of the air in the launch platform's environment. The flow field simulation process outputs heat transfer state coefficient data.

[0069] Step 220: Combine the flow field simulation output data, meteorological data and temperature change data in the platform objective data to form a simulation process of the overall temperature field of the launch platform.

[0070] The temperature change data in the platform's objective data include but are not limited to the launch platform's surface ambient temperature and relative humidity, and the meteorological data include but are not limited to solar radiation and cloud cover coefficient. Provide input state data for the near-field and far-field temperature simulation of the full-scale launch platform. According to the basic principles of heat conduction pathways and the laws of conduction media in the environment, a reasonable simulation process of the overall temperature field of the launch platform is established in combination with near-field and far-field temperature data and accumulated meteorological data and temperature change data to reflect the dynamic process of heat accumulation on the platform in the environment where the launch platform is located.

[0071] In the process of establishing the simulation, it is necessary to consider the arrangement of weather station data. For example, the temperature and relative humidity in spring and summer are selected as the average values ​​of three months per hour, while the temperature and relative humidity data are selected as the average values ​​of the hourly period during the measurement period. The temperature and relative humidity data are taken as the curve of changes over time within 24 hours of a day. There are three ways for objects to transfer heat, namely heat conduction, heat convection and heat radiation. For outdoor launch platforms, the most important are solar radiation and convection heat transfer with air, while the heat conduction of the ground also has an impact.

[0072] Step 230: Combining the temperature field simulation output data with the temperature and humidity change data in the platform objective data to form a launch platform relative humidity field simulation process.

[0073] The temperature field simulation reflects the factors affecting the far-field temperature and near-field temperature of the launch platform on the humidity environment of the platform surface. The temperature and humidity change data in the platform's objective data provide input state data for the humidity simulation of the micro-environment of the full-scale launch platform. According to the basic principles and critical laws of the correlation between the temperature and humidity of the platform surface, a reasonable simulation process of the overall relative humidity field of the launch platform is established in combination with the temperature, humidity data and existing experimental research results to reflect the dynamic process of water vapor accumulation in the environment of the launch platform.

[0074] Step 240: forming a condensation simulation process according to the time node data output by the humidity field simulation and the platform surface humidity change data in the platform objective data.

[0075] Limited by current computing power, existing technologies are unable to couple the temperature and humidity field simulation model with the condensation model, and are unable to track and calculate transient condensation changes throughout the day. By selecting the average temperature and humidity of the entire day as the environmental background state, the lower surface temperature of the launch platform at a typical time node of the day (such as the temperature data of the platform surface in the early morning) is extracted as the input state data for the condensation simulation of the micro-environment of the full-scale launch platform. Combining the basic principles, critical laws, existing experimental research results and empirical formulas of the correlation between temperature, humidity and condensation, a reasonable overall condensation simulation process for the launch platform is established to reflect the condensation rate, and further estimate the condensation amount, liquid film thickness and condensation distribution throughout the day.

[0076] The method for evaluating the severity level of the coastal service environment of a launch platform in an embodiment of the present invention combines multi-scale data, multi-field coupling environment and multiple empirical statistical analyses to use accumulated massive data to perform multi-dimensional progressive simulation modeling processing on the condensation state in the coastal service environment, so as to obtain accurate quantification of key factors of the harsh environment of metal corrosion, thereby forming an effective evaluation basis for the degree of metal corrosion.

[0077] like Figure 1 As shown, in one embodiment of the present invention, combined with Figure 2 As shown, step 300 includes:

[0078] Step 310: Verify the condensation simulation output through the on-site temperature and humidity and condensation test results in the platform objective data, and iteratively optimize the condensation simulation process according to the condensation simulation output deviation.

[0079] The condensation simulation process includes simulations of various fields. The simulation output deviation is formed by comparing the simulation output with the on-site temperature, humidity and condensation test results. The corresponding simulation process is corrected according to the simulation output deviation, and the true fit of the condensation simulation process is iteratively improved.

[0080] Step 320: Form an evaluation grade of the corrosion state according to the condensation simulation output result combined with the corrosion component data in the platform objective data.

[0081] The simulation process or linear trend description that is positively correlated with the corrosion state is formed based on the condensation data combined with the corrosion data in the platform's objective data. The corrosion data includes but is not limited to salt deposition and pH value. Based on the simulation calculation results and the salt deposition measured on the platform surface, the area with the largest salt deposition on the platform is determined. The evaluation criteria for the severity of the environment are finally determined based on the condensation situation.
