As described in the background art, due to the particularity of the working environment of the optical fiber hydrophone, the reliability of the package of the optical fiber hydrophone is subject to high requirements. The package of the optical hydrophone generally refers to a polyurethane watertight packaging material which is coated outside a metal matrix of the optical hydrophone and has sound transmission and waterproof functions. Reliable watertight packaging is an important prerequisite for determining whether the optical fiber hydrophone can work efficiently and stably in the submarine service period for years. The pressure is an important characteristic of the seawater environment, and is mainly generated under the action of the gravity of seawater, and the pressure is increased by about 1MPa when the water depth is increased by 100 m. Therefore, the packaging structure is a critical part in the optical fiber hydrophone, and firstly, the packaging structure needs to be sealed and waterproof, namely, the packaging structure can ensure effective isolation and sealing between an internal optical fiber device of the device and external seawater under high hydrostatic pressure; secondly, the sound transmission needs to be efficient, namely the packaging structure needs to be capable of efficiently transmitting external underwater sound pressure signals to be detected to an optical fiber sensitive coil inside the device, and target detection is achieved.
At present, the more general application scheme is to coat the polyurethane watertight packaging material outside the optical fiber hydrophone metal matrix, and have the sound transmission and waterproof functions, and after the whole optical fiber hydrophone metal matrix is completely coated by the packaging material, although the metal matrix will not be directly exposed to the seawater environment, the occurrence of metal corrosion is effectively prevented, the watertight packaging material will still be exposed to the seawater environment for a long time. Under the actual seabed working condition, the packaging material is inevitably degraded under the action of long-term high hydrostatic pressure seawater, so that the strength of the material is reduced, and the packaging leakage failure can occur after a certain degree is reached. Therefore, the optical fiber hydrophone package detection method provided by the embodiment of the application can be applied to an application environment for detecting the reliability of the optical fiber hydrophone package.
The optical fiber hydrophone package detection method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the detection platform 104 via a wired or wireless connection. The inspection platform 104 is equipped with a temperature control assembly, a pressure control assembly, etc. for establishing an inspection environment. The detection platform 104 is further equipped with a data acquisition device for acquiring test data during the detection process. The data storage system may store data that the terminal 102 needs to process. The data storage system may be integrated on the terminal 102, or may be placed on the cloud or other network server. The terminal 102 may be, but is not limited to, various personal or public computers, laptops, smartphones, tablets, internet of things devices, and portable wearable devices.
In some embodiments of the present disclosure, as shown in fig. 2, a method for detecting a package of a fiber optic hydrophone is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
step S10: determining a first test time of a first to-be-tested sample of the fiber optic hydrophone in a first test environment; the first detection environment comprises a hot seawater environment.
Specifically, a plurality of first samples to be tested of the optical fiber hydrophone are selected, and the first samples to be tested can be selected from the optical fiber hydrophone which is completely packaged. The number of the first samples to be tested is preferably not less than 4. The first detection environment is a hot seawater environment, and the test seawater is natural seawater which is filtered according to the first class in GB/T3097-1997-seawater quality standard, or artificial seawater which is prepared according to standard implementation regulations for preparing ASTMD1141:1998 instead of seawater. The test temperature of the first detection environment may be set according to actual requirements, for example, set to 60 ℃.
The first sample to be tested needs to be in the first testing environment for maintaining the first testing time so as to obtain the testing data in the first testing time. The setting of the first test time can be calculated or directly set by comprehensively considering the performance of the packaging material, the service life index requirement of the optical fiber hydrophone and the working environment of the optical fiber hydrophone.
Step S20: and monitoring first optical path data of the first sample to be detected in real time, and acquiring first optical path loss data of the first sample to be detected in the first test time according to the first optical path data.
Specifically, in a first test time when a first sample to be tested is in a first test environment, first optical path data of the first sample to be tested is monitored in real time through an optical circuit. And obtaining first optical path loss data of the first sample to be measured in the first test time by calculating the first optical path data at the starting time and the ending time of the first test time.
Step S30: and determining a second sample to be tested of which the first optical path loss data is smaller than a first threshold value in the first sample to be tested.
Specifically, based on the obtained first optical path loss data of the first sample to be detected, of which the first optical path loss data is smaller than the first threshold value, is screened as the second sample to be detected. The first threshold value may be calculated or directly set according to the performance of the packaging material of the optical fiber hydrophone and the life index requirement of the optical fiber hydrophone, and the operating environment of the optical fiber hydrophone, for example, the first threshold value may be set to 3 dB. And the rest first samples to be tested which are not screened as the second samples to be tested in the first samples to be tested are unqualified samples.
Step S40: monitoring second light path data of the second sample to be detected in a second detection environment in real time, and acquiring second light path loss data of the second sample to be detected in a second test time according to the second light path data; the second detection environment includes a high hydrostatic pressure environment.
Specifically, the determined second sample to be detected is transferred from the first detection environment to the second detection environment. And simultaneously monitoring second light path data of a second sample to be detected in a second detection environment in real time. The second sample to be tested also needs to be in the second testing environment for maintaining the second testing time so as to obtain the testing data in the second testing time. The setting of the second test time can be calculated or directly set by comprehensively considering the performance of the packaging material, the service life index requirement of the optical fiber hydrophone and the working environment of the optical fiber hydrophone. For example, the second test time set in the present embodiment is not less than 48 hours. And obtaining second optical path loss data of the second sample to be tested in the second test time by calculating second optical path data at the starting time and the ending time of the second test time.
The second detection environment is a high hydrostatic pressure environment, can be manufactured through a high-pressure water tank, and is arranged in the high-pressure water tank. The standard of the test seawater of the second test environment may be referenced to the test seawater of the first test environment. The hydrostatic pressure value of the second detection environment can be set according to the requirement of the maximum working water depth in GJB 23B-2018 Sonar transducer general Specification.
Step S50: and recording a second to-be-detected sample of which the second optical path loss data is smaller than a second threshold value in the second to-be-detected sample as a qualified sample.
Specifically, based on the obtained second optical path loss data of the second sample to be detected, of which the second optical path loss data is smaller than the second threshold value, is screened as a qualified sample and recorded. And obtaining qualified samples through two screenings in combination with the flow chart of the qualified sample determination shown in fig. 3. The second threshold may be calculated or directly set according to the performance of the packaging material of the optical fiber hydrophone, the life index requirement of the optical fiber hydrophone, and the working environment of the optical fiber hydrophone, for example, the second threshold may also be set to 3dB (decibel). And the rest second samples to be detected which are not screened as qualified samples in the second samples to be detected are unqualified samples.
According to the optical fiber hydrophone packaging detection method, the two detection environments are combined with each other, so that the packaging strength of the optical fiber hydrophone is degraded through hot seawater in an accelerating manner, the packaging strength reliability of the optical fiber hydrophone is further judged through hydrostatic pressure detection, the influence of the packaging degradation on the optical fiber hydrophone under a long-term seawater environment can be accurately evaluated, a detection system closer to the packaging reliability of the optical fiber hydrophone under the actual application working condition is established, and the subsequent detection, evaluation and optimization of the packaging of the optical fiber hydrophone are facilitated.
In some embodiments of the present disclosure, as shown in fig. 4, step S10 includes:
step S12: the working time of the optical fiber hydrophone is preset.
Specifically, the working time of the optical fiber hydrophone generally refers to the working time required by the actual working condition of the optical fiber hydrophone, the optical fiber hydrophone can be applied to various occasions such as underwater warning, seismic wave detection, petroleum seismic exploration, fish detection and the like, the working time of the optical fiber hydrophone is preset according to the working time of the optical fiber hydrophone required by different occasions, for example, the preset working time is TWork by。
Step S14: and calculating to obtain a first test acceleration coefficient according to the activation energy data of the optical fiber hydrophone and the working time.
Specifically, the first trial acceleration factor may refer to a ratio of a package life characteristic of the fiber optic hydrophone at a normal stress level to a corresponding life characteristic at an accelerated stress level. The first experimental acceleration coefficient can be obtained by calculation based on the activation energy data and the working time of the optical fiber hydrophone, and the formula is as follows:
Figure BDA0003526301220000081
wherein, AfIs the first test acceleration factor, EaFor activation energy, K is Boltzmann constant, TWorking temperatureThe optical fiber hydrophone is required to be under the actual working conditionWorking temperature of (T)Temperature testingIs the test temperature of the first test environment in kelvin. The activation energy data may be obtained by consulting the package material parameters of the fiber optic hydrophone, or by experimentally obtaining the activation energy data.
Step S16: and calculating to obtain the first test time according to the working time and the first test acceleration coefficient.
Specifically, the first test time can be obtained by calculation according to the preset working time and the first test acceleration coefficient, and the formula is as follows:
Figure BDA0003526301220000082
wherein, TTest ofFor the first test time, TWork byThe working time is the working time required by the actual working condition of the optical fiber hydrophone.

step A10: constructing a third detection environment, wherein the third detection environment comprises a plurality of groups of hot seawater environments with different temperatures; each group of hot seawater environments is provided with at least one encapsulated sample of fiber optic hydrophones.
Specifically, in this embodiment, before performing the above-mentioned detection step, the package activation energy data of the fiber optic hydrophone may be obtained through experiments. Activation energy generally refers to the energy required to move a crystal atom away from an equilibrium position to another new equilibrium or non-equilibrium position, also referred to as "activation energy". The energy that needs to be overcome in order to start a certain physicochemical process (e.g. plastic flow, atomic diffusion, chemical reaction, formation of vacancies, etc.). The energy can be provided by the energy fluctuation of the system and can also be provided by the outside. The smaller the activation energy, the easier the process will be. The package activation energy data of the fiber optic hydrophone may refer to the energy required for the package strength of the fiber optic hydrophone to degrade to a certain degree, and may be, for example, the energy required for degradation to 50%.
The packaged sample of the optical fiber hydrophone can be a completely packaged optical fiber hydrophone or a sample manufactured by the same packaging material and the same process conditions as the optical fiber hydrophone. In this example, a dumbbell-shaped 1A polyurethane packaging material sample is prepared according to GB/T528-2009 determination of tensile stress strain performance of vulcanized rubber or thermoplastic rubber. The number of packaged samples is preferably not less than 300.

The preset time can be set and adjusted according to the tensile strength degradation speed, for example, the preset time can be 24 hours, and in the process of extracting the packaging sample to obtain the tensile strength data, the preset time can be reasonably adjusted according to the actual test. For example, at low temperature, the predetermined time may be appropriately prolonged, and the predetermined time may be appropriately reduced after the tensile strength of the encapsulated sample is degraded at a later stage. The number of encapsulated samples drawn at a time may be 5.
Step A30: and stopping acquiring the tensile strength data until the acquired tensile strength data of the encapsulated sample is smaller than a preset strength threshold value.
Specifically, when all the tensile strength data of a plurality of packaged samples acquired at a time in a certain group of hot seawater environment is smaller than a preset strength threshold, the operation of extracting the packaged samples of the group is stopped.
