[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] In the field of security, disturbance signals sent by enemies or intruders are often generated in the external environment, which will affect our security. Therefore, it is necessary to accurately locate and identify the disturbance signals to facilitate our intervention or defense against the disturbance signals and ensure that we are in a safe environment. Among them, distributed fiber optic sensing equipment is implemented using fiber optic sensing technology. As an emerging security technology, fiber optic sensing technology has the advantages of small size, corrosion resistance, anti-electromagnetic interference, high sensitivity, and long-distance monitoring that are unique to optical fibers themselves, so distributed fiber optic sensing equipment is widely used in the field of security.

[0041] In practical applications, the distributed optical fiber sensing device locates and identifies the disturbance signal in the external environment by converting the external signal into an optical signal, and in the process of positioning and identifying, it is necessary to store the relevant signal (including at least one of the optical signal and the phase signal) and / or the positioning information to intervene or defend against the disturbance signal generated by the outside world and improve the safety of the external environment. In the related art, the distributed optical fiber sensing device mainly collects the external signal under the sampling mode corresponding to the high signal sampling rate, and locates and identifies the disturbance signal according to the optical signal corresponding to the external signal. However, in the process of locating and identifying the disturbance signal in the related art, there is a problem of high redundancy of signal storage. Based on this, the embodiment of the present application provides a sampling mode adjustment method, which can reduce the redundancy of signal storage while storing the relevant signal or information in the process of locating and identifying the disturbance signal, while ensuring that the effective signal required for positioning and identification is not affected.

[0042] The sampling mode adjustment method provided in the embodiment of the present application can be applied to a distributed optical fiber sensing device. The above-mentioned distributed optical fiber sensing device can be a distributed optical fiber acoustic wave sensing device, an ultra-low noise single-frequency laser, a signal coherent demodulation device, etc. The specific form of the distributed optical fiber sensing device is not limited in this embodiment. The following embodiment takes the distributed optical fiber sensing device as the execution subject of the sampling mode adjustment method to introduce the specific process of the sampling mode adjustment method.

[0043] As shown in FIG1 , it is a flow chart of a sampling mode adjustment method provided in an embodiment of the present application. The method can be implemented by the following steps:

[0044] S100: Under the current signal sampling mode, an optical signal corresponding to an original signal generated in an external environment is obtained.

[0045] The original signal may be a disturbance signal or a non-disturbance signal. Meanwhile, the current signal sampling mode may be a sampling mode corresponding to a high signal sampling rate or a sampling mode corresponding to a low signal sampling rate.

[0046] Specifically, the distributed optical fiber sensing device is in the current signal sampling mode, and can collect the original signal generated in the external environment in real time, and convert the original signal into an optical signal, that is, an optical signal corresponding to the original signal.

[0047] S200: Determine an adjustment state of a current signal sampling mode according to a phase signal of an optical signal.

[0048] In practical applications, the distributed optical fiber sensing device can first obtain the phase signal of the optical signal, and then determine the adjustment state of the current signal sampling mode according to the phase signal of the optical signal.

[0049] The phase signal of the optical signal may be obtained by performing conversion processing, analysis processing and / or matching processing on the optical signal.

[0050] In one embodiment, the method of determining the adjustment state of the current signal sampling mode according to the phase signal of the optical signal can be to pre-train an algorithm model, and then input the phase signal of the optical signal into the algorithm model, and the algorithm model outputs the adjustment state of the current signal sampling mode.

[0051] In another embodiment, the method for determining the adjustment state of the current signal sampling mode based on the phase signal of the optical signal can also be to search for the phase signal of the optical signal in the mapping relationship between different phase signals and different adjustment states, and determine the adjustment state corresponding to the phase signal that matches the phase signal of the optical signal as the adjustment state of the current signal sampling mode.

[0052] S300: When the adjustment state is yes, the current signal sampling mode is adjusted to a target signal sampling mode; the signal sampling rates of the target signal sampling mode and the current signal sampling mode are different.

[0053] In the embodiment of the present application, when it is determined that the adjustment state of the current signal sampling mode is yes, it indicates that the phase signal of the original signal is large and there may be an abnormality. At this time, the current signal sampling mode needs to be adjusted, and the current signal sampling mode can be further adjusted to the target signal sampling mode. Among them, the above-mentioned possible abnormality can be understood as the original signal may be a valid disturbance signal, or the original signal may be an invalid disturbance signal.

[0054] S400: Taking the target signal sampling mode as the current signal sampling mode, and continuing to execute the step of acquiring the optical signal corresponding to the original signal generated in the external environment.

[0055] Furthermore, the distributed optical fiber sensing device may use the target signal sampling mode as the current signal sampling mode, and continue to execute the above steps S100-S300 in a loop.

[0056] The technical solution in the embodiment of the present application is to obtain an optical signal corresponding to the original signal generated in the external environment under the current signal sampling mode, determine the adjustment state of the current signal sampling mode according to the phase signal of the optical signal, and when the adjustment state is yes, adjust the current signal sampling mode to the target signal sampling mode, use the target signal sampling mode as the current signal sampling mode, and continue to execute the step of obtaining the optical signal corresponding to the original signal generated in the external environment, wherein the signal sampling rate of the target signal acquisition mode is different from that of the current signal sampling mode; in the process of locating and identifying the disturbance signal, the above method can continuously adjust the signal sampling mode, and collect external disturbance signals under different signal sampling modes. The original signal generated in the environment is used to locate and identify the disturbance signal generated in the external environment, so that the amount of signal and / or information to be stored in different time periods can be dynamically changed. When storing relevant signals or positioning information, under the premise of ensuring that the effective signals required for positioning and identification are not affected, the redundancy of signal storage can be reduced, that is, the amount of stored signals and / or information can be reduced, and the storage pressure of distributed optical fiber sensing equipment can be reduced; at the same time, the above method does not require human participation, thereby improving the speed and efficiency of signal sampling mode adjustment, and timely reducing the redundancy of signal storage, and can also reduce the adjustment error caused by human participation, which can improve the correctness of signal sampling mode adjustment.

[0057] The process of obtaining the phase signal of the optical signal is described below. In one embodiment, before executing the step in S200 above, as shown in FIG2 , the method may further include the following steps:

[0058] S500: Demodulate the optical signal to obtain an original phase signal corresponding to the optical signal.

[0059] In practical applications, a distributed optical fiber sensing device can pre-train a demodulation model, and then input the optical signal into the demodulation model. The demodulation model demodulates the optical signal and outputs the original phase signal corresponding to the optical signal.

[0060] Optionally, the above demodulation model can be implemented by at least one of a convolutional neural network model, a fully connected neural network model, a long short-term memory neural network model, a recurrent neural network model, a residual neural network model, etc.

[0061] In the embodiment of the present application, the distributed optical fiber sensing device can use a phase demodulation algorithm to demodulate the optical signal to obtain the original phase signal corresponding to the optical signal. Optionally, the above phase demodulation algorithm can be an optical phase demodulation algorithm based on a 3x3 coupler, a heterodyne demodulation algorithm, a phase-generated carrier demodulation algorithm, etc., which is not limited in the embodiment of the present application.

[0062] S600: Preprocess the original phase signal to obtain a phase signal of the optical signal.

[0063] The distributed optical fiber sensing device may adopt a denoising algorithm to preprocess the original phase signal to obtain a phase signal of the optical signal. Optionally, the denoising algorithm may include at least one of a wavelet transform denoising algorithm, a median filter denoising algorithm, a Wiener filter denoising algorithm, an empirical mode decomposition denoising algorithm, a smoothing filter algorithm, etc.

[0064] The technical solution in the embodiment of the present application can demodulate the optical signal to obtain the original phase signal corresponding to the optical signal, so as to determine the fluctuation of the original signal based on the original phase signal, and provide reference information for adjusting the signal sampling mode. The original phase signal can be further pre-processed to obtain the precise phase signal of the optical signal. On this basis, it can provide reference information for precise adjustment of the signal sampling mode based on the precise phase signal.

[0065] The process of determining the adjustment state of the current signal sampling mode according to the phase signal of the optical signal is described below. In one embodiment, the steps in S200 above may include the following steps: when the phase signal is greater than a preset signal threshold, determining that the adjustment state of the current signal sampling mode is yes; when the phase signal is less than the signal threshold, determining that the adjustment state of the current signal sampling mode is no; wherein the signal sampling rate of the current signal sampling mode is less than the signal sampling rate of the target signal acquisition mode.

[0066] In an embodiment of the present application, the phase signal of the optical signal can represent the amplitude or intensity of the original signal corresponding to the optical signal. Taking the case where the signal sampling rate of the current signal sampling mode is less than the signal sampling rate of the target signal acquisition mode, the distributed optical fiber sensing device can determine whether the phase signal of the optical signal is greater than a preset signal threshold. When the phase signal of the optical signal is greater than the signal threshold, the adjustment state of the current signal sampling mode is determined to be yes. Optionally, the signal threshold can be user-defined or determined based on historical experience values.

[0067] Further, when it is determined that the adjustment state of the current signal sampling mode is yes, first warning information may be output to remind the user that the current signal sampling mode needs to be adjusted to the target signal sampling mode.

[0068] At the same time, when it is determined that the phase signal of the optical signal is less than the signal threshold, it is determined that the adjustment state of the current signal sampling mode is no.

[0069] Exemplarily, as shown in FIG3 , loop 2 is the process of maintaining the current signal sampling mode, and loop 3 is the process of maintaining the target signal sampling mode. Condition 1 is that the phase signal of the optical signal is less than the signal threshold, and condition 2 is that the phase signal of the optical signal is greater than the preset signal threshold. Correspondingly, loop 1 represents the process of switching back and forth between the current signal sampling mode and the target signal sampling mode.

[0070] According to the technical solution in the embodiment of the present application, when the phase signal is greater than a preset signal threshold, the adjustment state of the current signal sampling mode is determined to be yes, and when the phase signal is less than the signal threshold, the adjustment state of the current signal sampling mode is determined to be no; the above method can determine the adjustment state of the current signal sampling mode according to the size relationship between the phase signal of the optical signal and the preset signal threshold, so as to flexibly adjust the signal sampling mode to the optimal sampling mode, so that the amount of data collected during the positioning and identification process is small and no valid signal is missing. At the same time, the processing process does not require the participation of complex algorithms, and the processing process is relatively simple, thereby improving the speed and efficiency of determining the adjustment state of the current signal sampling mode, and can also reduce the amount of collected data, so as to help reduce the errors generated in the positioning and identification processes, and improve the efficiency of data storage during the sampling process.

[0071] In one embodiment, after the step in S200 is executed, the method may further include: when the adjustment state is no, maintaining the current signal sampling mode, continuing to execute the step of acquiring the optical signal corresponding to the original signal generated in the external environment, until the adjustment state of the current signal sampling mode is yes, and adjusting the current signal sampling mode to the target signal sampling mode.

[0072] In an embodiment of the present application, when it is determined that the adjustment state of the current signal sampling mode is no, it indicates that the phase signal of the original signal is small and there is no abnormality in the original signal. At this time, there is no need to adjust the current signal sampling mode. The current signal sampling mode is maintained and the step of obtaining the optical signal corresponding to the original signal generated in the external environment is continued until the adjustment state of the current signal sampling mode is yes, and the current signal sampling mode is adjusted to the target signal sampling mode.

[0073] In practical applications, the above sampling mode adjustment method can be implemented through a cyclic processing process, that is, a process of switching back and forth between the target signal sampling mode and the current signal sampling mode. The cyclic processing process can be executed all the time, but the triggering method for stopping the cyclic processing process under certain circumstances can be a passive triggering method.

[0074] It should be noted here that if the adjustment status of the target signal sampling mode is the second warning information, the user is reminded that the target signal sampling mode needs to be adjusted to the current signal sampling mode.

[0075] The technical solution in the embodiment of the present application can maintain the current signal sampling mode when the adjustment state of the current signal sampling mode is no to reduce the amount of sampled data. This not only reduces the storage pressure of the distributed optical fiber sensing equipment, but also does not affect the collection of effective signals required for locating and identifying disturbance signals generated in the external environment. In other words, it does not affect the effective signals required for positioning and identification, and can also reduce the redundancy of data storage.

[0076] In one embodiment, the optical signal includes a valid optical signal; after performing the step in S600, as shown in FIG4 , the method may further include the following steps:

[0077] S700: Store the phase signal corresponding to the effective optical signal.

[0078] In practical applications, optical signals may include invalid optical signals and valid optical signals; invalid optical signals may be optical signals acquired in the current signal acquisition mode, that is, signals that are not helpful for positioning and identification; the above-mentioned valid optical signals may be optical signals acquired in the target signal acquisition mode, that is, valid signals required for positioning and identification.

[0079] Specifically, the distributed optical fiber sensing device can demodulate the effective optical signal to obtain a phase signal corresponding to the second optical signal, and further, can store the phase signal corresponding to the effective optical signal.

[0080] S800: Determine, according to the phase signal of the effective optical signal, a signal type corresponding to an original signal for generating the effective optical signal.

[0081] In an embodiment of the present application, in order to reduce the amount of data processed during positioning and identification and to increase the accuracy and speed of positioning and identification, the signal type corresponding to the original signal that generates the effective optical signal can be determined based on the phase signal of the effective optical signal.

[0082] Among them, the distributed optical fiber sensing device can search for the phase signal of the effective optical signal in the mapping relationship between different phase signals and different signal types, and determine the signal type corresponding to the phase signal that matches the phase signal of the effective optical signal in the mapping relationship as the signal type corresponding to the original signal of the effective optical signal.

[0083] In addition, the distributed optical fiber sensing device can also pre-train a recognition model, and then input the phase signal of the effective optical signal into the recognition model, and the recognition model outputs the disturbance signal type of the original signal of the effective optical signal. Optionally, the above recognition model can be composed of at least one of a convolutional neural network model, a fully connected neural network model, a long short-term memory neural network model, a recurrent neural network model, a residual neural network model, etc.

[0084] In one embodiment, after executing the step in S600, the method may further include: performing positioning processing on an original signal that generates the effective optical signal according to the effective optical signal and a phase signal of the effective optical signal, and determining positioning information of the original signal.

[0085] In practical applications, the distributed optical fiber sensing device can perform positioning processing on the original signal that generates the effective optical signal based on the effective optical signal and the phase signal of the effective optical signal to determine the positioning information of the original signal.

[0086] In one embodiment, the distributed optical fiber sensing device can pre-train a positioning algorithm model, and then input both the effective optical signal and the phase signal of the effective optical signal into the positioning algorithm model. The positioning algorithm model performs positioning processing on the original signal that generates the effective optical signal to obtain the positioning information of the original signal.

[0087] In another embodiment, the distributed optical fiber sensing device can perform time division processing on the effective optical signal and the phase signal of the effective optical signal to complete the positioning processing of the original signal that generates the effective optical signal and obtain the positioning information of the original signal.

[0088] This embodiment can perform positioning processing on the original signal that generates the effective optical signal based on the effective optical signal and the phase signal of the effective optical signal, and determine the positioning information of the original signal, so as to be able to issue an early warning in time based on the positioning information, prompting the user to perform corresponding operations on the disturbance signal in the external environment, thereby reducing the loss or harm caused by the interference to us.

[0089] The technical solution in the embodiment of the present application can store the phase signal corresponding to the effective optical signal for use in subsequent analysis. At the same time, the signal type corresponding to the original signal that generates the effective optical signal can be determined based on the phase signal of the effective optical signal, so that effective measures can be taken to intervene or defend against interference based on the signal type corresponding to the original signal generated in the environment, thereby reducing the loss or harm caused by the interference to us.

[0090] In one embodiment, the present application also provides a sampling mode adjustment method, which is applied to a distributed optical fiber sensing device, and the method includes the following process:

[0091] (1) Under the current signal sampling mode, obtain the optical signal corresponding to the original signal generated in the external environment;

[0092] (2) Demodulate the optical signal to obtain the original phase signal corresponding to the optical signal;

[0093] (3) Preprocessing the original phase signal to obtain the phase signal of the optical signal;

[0094] (4) determining the adjustment state of the current signal sampling mode according to the phase signal of the optical signal;

[0095] (5) When the phase signal is greater than a preset signal threshold, it is determined that the adjustment state of the current signal sampling mode is yes; the signal sampling rate of the current signal sampling mode is less than the signal sampling rate of the target signal acquisition mode; when the phase signal is less than the signal threshold, it is determined that the adjustment state of the current signal sampling mode is no;

[0096] (6) When the adjustment state is yes, the current signal sampling mode is adjusted to the target signal sampling mode, and the target signal sampling mode is used as the current signal sampling mode, and the step of acquiring the optical signal corresponding to the original signal generated in the external environment is continued; the signal sampling rate of the target signal acquisition mode is different from that of the current signal sampling mode;

[0097] (7) When the adjustment state is no, the current signal sampling mode is maintained, and the step of acquiring the optical signal corresponding to the original signal generated in the external environment is continued until the adjustment state of the current signal sampling mode is yes, and the current signal sampling mode is adjusted to the target signal sampling mode; the optical signal includes a valid optical signal;

[0098] (8) Storing the phase signal corresponding to the effective optical signal;

[0099] (9) determining the signal type corresponding to the original signal that generates the effective optical signal according to the phase signal of the effective optical signal;

[0100] (10) Based on the effective optical signal and the phase signal of the effective optical signal, the original signal that generates the effective optical signal is positioned and processed to determine the positioning information of the original signal.
