At the same time, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.

[0070] As described in the background technology, due to the particularity of the working environment of the fiber optic hydrophone, the packaging reliability of the fiber optic hydrophone faces higher requirements. The packaging of the optical hydrophone usually refers to the polyurethane watertight packaging material that is coated on the outside of the metal matrix of the fiber optic hydrophone and has both sound-transmitting and waterproof functions. Reliable watertight packaging is an important prerequisite for determining whether the fiber optic hydrophone can work efficiently and stably during its years of submarine service. Pressure is an important feature of the seawater environment, which is mainly caused by the gravity of seawater. For every 100m increase in water depth, the pressure increases by about 1MPa. Therefore, the packaging structure is an extremely critical part of the fiber optic hydrophone. First, it must be sealed and waterproof, that is, the packaging structure must be able to ensure effective isolation and sealing between the optical fiber device inside the device and the external seawater under high hydrostatic pressure; second, it must be efficient and sound-transmitting, that is, the packaging structure must also be able to efficiently transmit the external underwater sound pressure signal to be measured to the optical fiber sensitive coil inside the device to achieve target detection.

[0071] At present, the more common application scheme is to coat the outside of the metal matrix of the fiber optic hydrophone with polyurethane watertight packaging material, which has both sound-permeable and waterproof functions. After the entire fiber optic hydrophone metal matrix is ​​completely coated with the packaging material, although the metal matrix will not be directly exposed to the seawater environment, effectively preventing metal corrosion, the watertight packaging material will still be exposed to the seawater environment for a long time. Under actual seabed conditions, under the action of long-term high hydrostatic pressure seawater, the packaging material will inevitably degrade, resulting in a decrease in material strength. After reaching a certain level, packaging leakage failure will occur. Therefore, the fiber optic hydrophone packaging detection method provided in the embodiment of the present application can be applied to the application environment of reliability detection of fiber optic hydrophone packaging.

[0072] The optical fiber hydrophone packaging detection method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the terminal 102 communicates with the detection platform 104 through a wired or wireless connection. The detection platform 104 is equipped with a temperature control component, a pressure control component, etc., for establishing a detection environment. The detection platform 104 is also equipped with a data acquisition device for acquiring test data during the detection process. The data storage system can store the data that the terminal 102 needs to process. The data storage system can be integrated on the terminal 102, or it can be placed on the cloud or other network servers. Among them, the terminal 102 can be, but is not limited to, various personal or public computers, laptops, smart phones, tablets, Internet of Things devices, and portable wearable devices.

[0073] In some embodiments of the present disclosure, Figure 2 As shown, a fiber optic hydrophone packaging detection method is provided, and the method is applied to Figure 1 The terminal in is used as an example to illustrate, including the following steps:

[0074] Step S10: Determine a first test time for a first sample to be tested of the fiber optic hydrophone to be in a first test environment; the first test environment includes a hot seawater environment.

[0075] Specifically, several first samples to be tested of the fiber optic hydrophone are selected, and the first samples to be tested can be fiber optic hydrophones that are well packaged. The number of first samples to be tested is preferably not less than 4. The first test environment is a hot seawater environment, and the test seawater is the first type of filtered natural seawater that meets the "GB / T 3097-1997-Seawater Quality Standard", or it is artificial seawater configured with reference to the "ASTMD1141:1998 Standard Practice for Preparation of Alternative Seawater". The test temperature of the first test environment can be set according to actual needs, for example, set to 60°C.

[0076] The first sample to be tested needs to be in the first testing environment for a first testing time to obtain testing data within the first testing time. The first testing time can be calculated or directly set by comprehensively considering the performance of the packaging material, the life index requirements of the optical fiber hydrophone, and the working environment of the optical fiber hydrophone.

[0077] Step S20: monitoring the first optical path data of the first sample to be tested in real time, and acquiring the first optical path loss data of the first sample to be tested within the first test time according to the first optical path data.

[0078] Specifically, during the first test time when the first sample to be tested is in the first detection environment, the first optical path data of the first sample to be tested is monitored in real time by the optical circuit. The first optical path loss data of the first sample to be tested during the first test time is obtained by calculating the first optical path data at the start and end of the first test time.

[0079] Step S30: determining a second sample to be tested whose first optical path loss data is smaller than a first threshold value among the first samples to be tested.

[0080] Specifically, based on the obtained first optical path loss data of the first sample to be tested, the first sample to be tested whose first optical path loss data is less than the first threshold is selected as the second sample to be tested. The first threshold can be calculated or directly set according to the packaging material performance of the optical fiber hydrophone, the life index requirements of the optical fiber hydrophone, and the working environment of the optical fiber hydrophone. For example, the first threshold can be set to 3dB. Among them, the remaining first samples to be tested that are not selected as the second samples to be tested in the first samples to be tested are unqualified samples.

[0081] Step S40: real-time monitoring of the second optical path data of the second sample to be tested in a second testing environment, and obtaining the second optical path loss data of the second sample to be tested within a second test time according to the second optical path data; the second testing environment includes a high hydrostatic pressure environment.

[0082] Specifically, the determined second test sample is transferred from the first test environment to the second test environment. At the same time, the second optical path data of the second test sample in the second test environment is monitored in real time. The second test sample also needs to be in the second test environment for a second test time to obtain the test data within the second test time. The second test time can be set by comprehensively considering the performance of the packaging material, the life index requirements of the fiber optic hydrophone, and the working environment of the fiber optic hydrophone for calculation or direct setting. For example, the second test time set in this embodiment is not less than 48 hours. By calculating the second optical path data at the start and end of the second test time, the second optical path loss data of the second test sample within the second test time is obtained.

[0083] The second test environment is a high hydrostatic pressure environment, which can be created by a high-pressure water tank, and the second sample to be tested is placed in the high-pressure water tank. The standard of the test seawater in the second test environment can refer to the test seawater in the first test environment. The hydrostatic pressure value of the second test environment can be set according to the maximum working water depth requirements in the "GJB 23B-2018 General Specifications for Sonar Transducers".

[0084] Step S50: Record the second samples to be tested whose second optical path loss data is less than the second threshold value as qualified samples.

[0085] Specifically, based on the obtained second optical path loss data of the second sample to be tested, the second sample to be tested whose second optical path loss data is less than the second threshold is selected as a qualified sample and recorded. Figure 3The flow chart for determining qualified samples is shown in the figure, and qualified samples are obtained through two screenings. The second threshold value can be calculated or directly set according to the packaging material performance of the optical fiber hydrophone, the life index requirements of the optical fiber hydrophone, and the working environment of the optical fiber hydrophone. For example, the second threshold value can also be set to 3dB (decibel). Among them, the remaining second samples to be tested that are not screened as qualified samples in the second samples to be tested are unqualified samples.

[0086] In the above-mentioned fiber optic hydrophone packaging inspection method, the two inspection environments are combined with each other so that the packaging strength of the fiber optic hydrophone is accelerated to degrade by hot seawater. The reliability of the packaging strength of the fiber optic hydrophone is further judged by hydrostatic pressure inspection. The impact of packaging degradation on the fiber optic hydrophone in a long-term seawater environment can be accurately evaluated. A packaging reliability inspection system that is closer to the actual application conditions of the fiber optic hydrophone is established, which is helpful for subsequent inspection, evaluation and optimization of the packaging of the fiber optic hydrophone.

[0087] In some embodiments of the present disclosure, Figure 4 As shown, step S10 includes:

[0088] Step S12: Preset the working time of the fiber optic hydrophone.

[0089] Specifically, the working time of the fiber optic hydrophone generally refers to the working time required by the actual working conditions of the fiber optic hydrophone. The fiber optic hydrophone can be used in various occasions such as underwater warning, seismic wave detection, oil seismic exploration, and fish school detection. In this embodiment, the working time of the fiber optic hydrophone is preset according to the working time of the fiber optic hydrophone required in different occasions. For example, the preset working time is T 工作 .

[0090] Step S14: Calculate and obtain a first test acceleration coefficient according to the activation energy data of the fiber optic hydrophone and the working time.

[0091] Specifically, the first test acceleration factor may refer to the ratio of the packaging life characteristics of the optical fiber hydrophone under normal stress level to the corresponding life characteristics under accelerated stress level. The first test acceleration factor may be calculated based on the activation energy data and working time of the optical fiber hydrophone, and the formula is as follows:

[0092]

[0093] Among them, A f is the first test acceleration factor, E a is the activation energy, K is the Boltzmann constant, T 工温 is the operating temperature of the fiber optic hydrophone under actual working conditions, T 试温is the test temperature of the first detection environment, in Kelvin. The activation energy data can be obtained by consulting the packaging material parameters of the fiber optic hydrophone, or by experiments.

[0094] Step S16: Calculate the first test time according to the working time and the first test acceleration coefficient.

[0095] Specifically, the first test time can be calculated according to the preset working time and the first test acceleration coefficient, and the formula is as follows:

[0096]

[0097] Among them, T 试验 is the first test time, T 工作 This is the working time required for the actual working conditions of the fiber optic hydrophone.

[0098] This embodiment conducts a hot seawater water bath accelerated life test in a first detection environment, and obtains a first test time based on the working time of the fiber optic hydrophone, the working temperature under actual working conditions, and the test temperature, thereby improving the fit between the fiber optic hydrophone packaging test and the actual working conditions and greatly improving the detection accuracy.

[0099] In some embodiments of the present disclosure, Figure 5 As shown, the steps for obtaining activation energy data include:

[0100] Step A10: construct a third detection environment, wherein the third detection environment includes a plurality of groups of hot seawater environments with different temperatures; each group of hot seawater environments is provided with at least one packaged sample of a fiber optic hydrophone.

[0101] Specifically, before performing the above-mentioned detection steps in this embodiment, the packaging activation energy data of the fiber optic hydrophone can be obtained through experiments. Activation energy generally refers to the energy required to cause crystal atoms to leave the equilibrium position and migrate to another new equilibrium or non-equilibrium position, also known as "activation energy". The energy that needs to be overcome in order to start a certain physical and chemical process (such as plastic flow, atomic diffusion, chemical reaction, formation of vacancies, etc.). This energy can be provided by the energy fluctuations of the system itself, or by the outside world. The smaller the activation energy, the easier the process is to proceed. The packaging activation energy data of the fiber optic hydrophone may refer to the energy required for the packaging strength of the fiber optic hydrophone to degrade to a certain degree, for example, it may be the energy required when it degrades to 50%.

[0102] The packaging sample of the fiber optic hydrophone can be a fiber optic hydrophone with good packaging, or a sample made of the same packaging material and the same process conditions as the fiber optic hydrophone. In this embodiment, a dumbbell-shaped 1A polyurethane packaging material sample is prepared according to "GB / T 528-2009 Determination of tensile stress-strain properties of vulcanized rubber or thermoplastic rubber". The number of packaging samples is preferably not less than 300.

[0103] Among them, the third test environment includes several groups of hot seawater environments with different temperatures. This embodiment comprehensively considers preventing failure mechanism mutation and test time cost, and sets the temperature stress to 50℃, 60℃, 70℃, and 80℃, forming four groups of hot seawater environments with different temperatures. The number of package samples is set considering the degradation rate and can be set to 50-125.

[0104] Step A20: Acquire the tensile strength data of a plurality of the packaged samples extracted from each group of hot seawater environments at a preset time interval.

[0105] Specifically, several packaged samples extracted from each group of hot seawater environments at preset intervals are subjected to tensile strength tests in accordance with GB / T528-2009 Determination of tensile stress-strain properties of vulcanized rubber or thermoplastic rubber to obtain tensile strength data. The preset time can be set and adjusted according to the tensile strength degradation rate. For example, the preset time can be 24 hours. In the process of extracting packaged samples to obtain tensile strength data, the preset time can be reasonably adjusted according to the actual test situation. For example, at low temperatures, the preset time can be appropriately extended, and the preset time can be appropriately reduced after the tensile strength of the packaged samples degrades in the later stage. The number of packaged samples extracted each time can be 5.

[0106] Step A30: until the tensile strength data of the packaged sample obtained is less than a preset strength threshold, stop obtaining the tensile strength data.

[0107] Specifically, when the tensile strength data of several package samples obtained in a certain group of hot seawater environments are all less than a preset strength threshold, the operation of extracting package samples of the group is stopped. The preset strength threshold may be 50% of the initial strength of the package samples.

[0108] Step A40: Calculate the activation energy data based on the acquired tensile strength data.

[0109] Specifically, when the tensile strength data of several packaged samples acquired at a certain time in the hot seawater environment of each group are all less than the preset strength threshold, after the extraction steps of all groups are completed, the activation energy data is calculated based on the acquired tensile strength data.

[0110] In this embodiment, by manufacturing a packaging sample of the optical fiber hydrophone and conducting a hot seawater water bath accelerated life test on the packaging sample, the activation energy data of the packaging material of the optical fiber hydrophone can be obtained more accurately, which is more in line with the actual working condition requirements of the optical fiber hydrophone.

[0111] In some embodiments of the present disclosure, Figure 6 As shown, the above step A40 includes:

[0112] Step A42: establishing a tensile strength model corresponding to each set of hot seawater environments according to each set of hot seawater environments and the tensile strength data.

[0113] Specifically, the tensile strength data obtained during the experiment of each group of hot seawater environment were summarized, the tensile strength data of each group of packaged samples were recorded, and the average tensile strength was calculated. The tensile strength model corresponding to each group of hot seawater environment was established according to the following formula:

[0114] E1=a·eXp(-k1·t1 b )

[0115] E2=a·exp(-k2·t2 b )

[0116] E3=a·exp(-k3·t3 b )

[0117] E4=a·eXp(-k4·t4 b )

[0118] Among them, E i is the average tensile strength of the i-th group of hot seawater environment packaging samples, (i = 1, 2, 3, 4); k i is the degradation rate constant corresponding to the i-th group of thermal seawater environment, (i = 1, 2, 3, 4); t i is the degradation time when the tensile strength data of several packaged samples obtained at a certain time corresponding to the i-th group of hot seawater environment are all less than the preset strength threshold, (i=1, 2, 3, 4); a and b are constants independent of temperature.

[0119] Step A44: obtaining several groups of degradation rate constants at different temperatures according to the tensile strength model, and obtaining the activation energy data according to the degradation rate constants.

[0120] Specifically, based on the above four sets of tensile strength models, the degradation rate constant corresponding to the hot seawater environment can be calculated. The activation energy data is obtained according to the degradation rate constant using the following formula:

[0121] lnk=A+E a / RT

[0122] Among them, A is a constant, E a is the activation energy data, R is the gas constant, and T is the absolute temperature.

[0123] In this embodiment, a tensile strength model corresponding to each group of hot seawater environments is established to obtain the degradation rate constant corresponding to each group of hot seawater environments, and activation energy data is calculated according to the degradation rate constants corresponding to different temperatures, thereby improving the accuracy of obtaining the activation energy data of the optical fiber hydrophone package.
