On the other hand, since the first optical signal and the second optical signal can serve as backup signals for each other, if the first information is determined to be abnormal, the first device can send the same second information as the first information to the second device based on the backup signal without performing any maintenance processing, thus improving the communication stability of the communication system in specific scenarios (such as scenarios with high maintenance difficulty).

[0038] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. To facilitate a clear description of the technical solutions of the embodiments of this application, the use of terms such as "first," "second," etc., in the embodiments of this application is merely illustrative and for distinguishing the objects being described. There is no particular order between them, nor does it indicate a specific limitation on the number of devices in the embodiments of this application, and they do not constitute any limitation on the embodiments of this application.

[0039] Optical sensing technology is widely used in various scenarios to perform corresponding tasks.

[0040] Taking optoelectronic communication (or optoelectronic signal transmission) scenarios (e.g., terrestrial optical cable communication scenarios) as an example, Figure 1 This is a schematic diagram illustrating a scenario of optoelectronic communication according to some embodiments of the present disclosure. For example... Figure 1 As shown, this scenario typically includes at least two types of devices, such as the first device and the second device illustrated in the figure. The first device can be understood as a device capable of acquiring optical signals and demodulating them to obtain the information carried by the optical signals. The second device can be understood as a device capable of acquiring the information carried by the optical signals transmitted by the first device and performing corresponding parsing (e.g., signal parsing or parsing of the information carried by the signal). It is understood that the first device and the second device have a communication relationship; for example, the first device can directly report the information obtained from demodulating the optical signals to the second device through a corresponding communication link.

[0041] Continuing with the above scenario, in related technologies, due to the relatively low difficulty of equipment maintenance in this scenario, and for the sake of lightweight communication system design, the processing mechanism of the first device in the above scenario is usually designed as follows: when the first device acquires an optical signal (e.g., which can be referred to as the input optical signal), the input optical signal is demodulated, and then the demodulated information is reported to the second device. This allows relevant technicians to address communication anomalies (e.g., the second device's information parsing is abnormal due to a malfunction in the first device) by replacing the first device or its related components.

[0042] However, with the development of optoelectronic technology, optoelectronic communication scenarios are no longer limited to the above-mentioned scenarios. Taking submarine cable communication as an example, the first device is often set up in scenarios with high maintenance difficulty (e.g., underwater scenarios). Understandably, in submarine cable communication scenarios, if a communication anomaly occurs (e.g., the second device's information parsing is abnormal due to a malfunction of the first device), relevant technical personnel cannot perform maintenance in a timely manner, which may increase the duration of communication anomalies and reduce the stability of the communication system.

[0043] In view of this, this disclosure proposes a communication method applied to a first device, wherein the first device includes an electronic device installed underwater. By splitting the acquired input optical signal, a first optical signal and a second optical signal with the same information as the input optical signal are obtained. The first device first sends the information carried by the second optical signal to a second device via a first communication link for initial communication. If the initial communication fails, the first device then sends the information carried by the second optical signal to the second device via the same communication link or a different communication link. Since the first and second optical signals are optical signals obtained by splitting the input optical signal, and the information carried by the first and second optical signals is the same as the information carried by the input optical signal, the first device completes a backup of the information to be sent before the initial communication between the first and second devices. Furthermore, in the event of an initial communication failure between the first and second devices, the backup information can be sent using either the same communication link or a different communication link, enabling the first device to complete communication with the second device without maintenance, thus improving the stability of the communication system.

[0044] To facilitate understanding, some technical terms in the relevant embodiments of this disclosure will be explained below:

[0045] Beam splitting: In the field of optoelectronic technology, beam splitting can be understood as the process of dividing a beam of incident light into two or more beams of light according to a specific ratio or method. In the embodiments of this disclosure, beam splitting can be understood as the operation of obtaining a first optical signal and a second optical signal based on the split optical signal.

[0046] The embodiments described below are some of the embodiments of this disclosure and do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0047] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0048] It should be noted that the communication method provided in this disclosure can be applied to electronic devices. Electronic devices may include, for example, terminals. Terminals include, but are not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, underwater power supply (UPS), marine communication (MC), optical communication (OC), photoelectric transmission (MT), optical sensing (OS), virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0049] Figure 2A This is a flowchart illustrating a communication method according to some embodiments of the present disclosure. Figure 1 .like Figure 2A As shown, the method is applied to a first device, which may be, for example, an electronic device installed underwater. The method includes the following steps S11 to S13.

[0050] In step S11, the acquired input optical signal is split into beams to obtain a first optical signal and a second optical signal.

[0051] In step S12, first information is sent to the second device based on the first communication link.

[0052] In step S13, if the first information is determined to be abnormal information, the second information is sent to the second device based on the first communication link, or the second information is sent to the second device based on the second communication link.

[0053] In this system, the first information carried by the first optical signal is the same as the information carried by the input optical signal, and the second information carried by the second optical signal is the same as the information carried by the input optical signal. The first information is obtained by the first device sampling the first optical signal. The second information is obtained by the first device sampling the second optical signal, and the second communication link is different from the first communication link.

[0054] In this embodiment, on the one hand, since the first optical signal and the second optical signal are optical signals obtained by splitting the input optical signal, and the information carried by the first optical signal is the same as the information carried by the input optical signal, and the information carried by the second optical signal is the same as the information carried by the input optical signal, the first optical signal and the second optical signal can serve as backup signals for each other. Therefore, if the first device sends abnormal first information to the second device, it can resend the backup second information, increasing the likelihood of successful communication between the first and second devices. On the other hand, since the first optical signal and the second optical signal can serve as backup signals for each other, if the first information is determined to be abnormal, the first device can send the same second information as the first information to the second device based on the backup signal without performing any maintenance processing, thus improving the communication stability of the communication system in specific scenarios (such as scenarios with high maintenance difficulty).

[0055] The input optical signal can also be referred to as the incident optical signal. For example, it can be understood as the optical signal (e.g., light rays) that the first device can acquire through a corresponding signal channel.

[0056] In some implementations, the number of input optical signals can be one or more. For example, the first device can acquire the corresponding input optical signal based on a single signal channel, or the first device can acquire the input optical signal corresponding to each of the multiple signal channels.

[0057] In some implementations, the first device acquires the input optical signal in at least one of the following ways: by acquiring the input optical signal detected by the sensor, or by acquiring the input optical signal sent by the upstream device, etc., but not limited to these.

[0058] The first and second signals can be understood, for example, as the optical signals obtained by the first device after splitting the input optical signal. The first and second optical signals have the same (or similar) optical signals as the input optical signal (e.g., light intensity, phase, frequency, or spectral distribution).

[0059] The information carried by an optical signal (e.g., the information carried by the input optical signal, the information carried by the first optical signal, or the information carried by the second optical signal) can be understood as the information represented by the demodulated properties of the optical signal (e.g., light intensity, phase, frequency, or spectral distribution).

[0060] In some implementations, when the number of input optical signals acquired by the first device is multiple, the input optical signals are split into multiple first optical signals and multiple second optical signals are obtained.

[0061] For example, assuming the first device acquires A input optical signals (where is a positive integer), after splitting the A input optical signals, the number of first optical signals obtained is A, and the number of second optical signals obtained is A. Furthermore, since both the first and second optical signals are optical signals obtained after splitting the input optical signals, there is a one-to-one correspondence between the first information carried by each of the A first optical signals and the second information carried by each of the A second optical signals (for ease of understanding, this is referred to as the first correspondence).

[0062] When the first device sends first information to the second device based on the first communication link, it can be understood as the first device sending the information carried by the input optical signal to the second device.

[0063] Understandably, in some scenarios (for example, referred to as scenario A1), the first information is determined to be the information to be sent first, that is, the first optical signal is determined to be the optical signal corresponding to the information to be sent first, and the second signal is the backup signal of the first optical signal.

[0064] Of course, in some scenarios (for example, referred to as scenario B1), the second information can be determined as the information to be sent first. That is, the second optical signal is determined as the optical signal corresponding to the information to be sent first, and the first signal is the backup signal of the second optical signal. This is not limited here.

[0065] The first communication link can be understood, for example, as a communication link in which the first device establishes a communication interaction relationship with the second device based on a first communication unit (e.g., a first communication unit deployed on the first device). The second communication link can be understood, for example, as a communication link in which the first device establishes a communication interaction relationship with the second device based on a second communication unit (e.g., a second communication unit deployed on the first device, and the second communication unit is different from the first communication unit).

[0066] If the first piece of information is determined to be abnormal, it can be understood as the first piece of information obtained by the second device being different from the predetermined normal information. For example, it could be that some information is missing, all information is missing, the second device did not obtain the first piece of information sent by the first device, or the sampling results of some channels are inaccurate, etc.

[0067] The reason why the first piece of information is determined to be abnormal can be determined, for example, by the first device communicating with the second device.

[0068] It should be noted that in the embodiments of this disclosure, "acquire", "obtain", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, autonomous implementation, and other meanings.

[0069] In some implementations, terms such as "send", "transmit", "report", "distribute", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0070] In some implementations, the first device may also acquire feedback information sent by the second device, wherein the feedback information is used to characterize the reason why the first information is determined to be abnormal information.

[0071] For example, the reason why the first piece of information is identified as abnormal information is contained in the feedback information.

[0072] In some implementations, the second device may be used to determine whether the first information is abnormal information, and send the determination result and / or the cause of the abnormality (if the second device determines that the first information is abnormal information) to the first device in the form of feedback information.

[0073] To facilitate understanding, the following will be explained... Figure 2B The implementation scenarios shown are exemplary illustrations of the implementation scenarios corresponding to the above-mentioned related implementation methods.

[0074] Figure 2B This is a scenario illustration of a communication method according to some embodiments of the present disclosure. Figure 1 .like Figure 2B As shown, the scenario includes a first device and a second device. The first device can acquire an input optical signal (e.g., input optical signal 1 and input optical signal 2 as shown in the figure). The first device can split the input optical signal (e.g., split input optical signal 1 and input optical signal 2 respectively based on the splitting unit in the figure) to obtain a first optical signal (e.g., first optical signal 1 and first optical signal 2 as shown in the figure) and a second optical signal (e.g., second optical signal 1 and second optical signal 2 as shown in the figure).

[0075] It is understandable that, upon receiving the first optical signal and the second optical signal, the first device can perform corresponding sampling processing (for example, sampling the first optical signal 1 and the first optical signal 2 through the first sampling unit, and / or sampling the second optical signal 1 and the second optical signal 2 through the second sampling unit) to obtain the information carried by the first optical signal and / or the information carried by the second optical signal, etc.

[0076] It should be noted that in the relevant embodiments of this disclosure, the sampling unit (e.g., the first sampling unit or the second sampling unit) is understood as a unit that can obtain the information carried by the optical signal based on the optical signal (e.g., it can perform sampling and demodulation and other related tasks).

[0077] For example, the first device samples and demodulates the first optical signal 1 and the first optical signal 2 respectively to obtain the information carried by the first optical signal 1 (which is the same as the information carried by the input optical signal 1) and the information carried by the first optical signal 2 (which is the same as the information carried by the input optical signal 2). The first device can also sample and demodulate the second optical signal 1 and the second optical signal 2 respectively to obtain the information carried by the second optical signal 1 (which is the same as the information carried by the input optical signal 1) and the information carried by the second optical signal 2 (which is the same as the information carried by the input optical signal 2).

[0078] When the first device receives the information carried by the first optical signal and / or the information carried by the second optical signal, it can send information to the second device based on the corresponding communication link.

[0079] It should be noted that, in the relevant embodiments of this disclosure, the first information can be understood, for example, as the information carried by all the first optical signals. Figure 2B For example, the first information can be understood as the information carried by the first optical signal 1 and the information carried by the first optical signal 2 (for example, the first device can obtain the first information by splicing or integrating the information carried by the first optical signal 1 and the information carried by the first optical signal 2).

[0080] It should also be noted that, in the relevant embodiments of this disclosure, the second information can be understood, for example, as the information carried by all the second optical signals. Figure 2B For example, the second information can be understood as the information carried by the second optical signal 1 and the information carried by the second optical signal 2 (for example, the first device can obtain the second information by splicing or integrating the information carried by the second optical signal 1 and the information carried by the second optical signal 2).

[0081] Continuing with scenario A1 above, when an electronic device obtains the first information and / or the second information, the first device will send the first information to the second device based on the first communication link (for example, the first device implements this through the first communication unit in the figure).

[0082] If the first device is identified as having abnormal information, the first device will send second information to the second device via the first communication link (for example, the first device can output the second information to the first communication unit in the figure, and implement this through the first communication unit). Alternatively, the first device may also send the second information to the second device via the second communication link (for example, the first device can output the second information to the first communication unit in the figure through the second communication unit).

[0083] Understandably, based on Figure 2B As shown in the scenario, the first piece of information is determined to be abnormal information, which may correspond to different causes as shown in examples A2) to D2) below.

[0084] A2) For example, if the first information is determined to be abnormal information due to the lack of some information, the corresponding reason may be that the first device lacks information corresponding to some sampling channels during the sampling process of the first optical signal.

[0085] B2) For example, if the first information is determined to be abnormal information due to the lack of all information, the corresponding reason may be that the information corresponding to all sampling channels of the first optical signal is missing during the sampling process, or that the first communication link is abnormal, resulting in the loss of all information of the first information.

[0086] C2) For example, if the second device determines that the first information is abnormal because it did not obtain the first information sent by the first device, the corresponding reason may be that the first optical signal was not sampled in all sampling channels during the sampling process, resulting in the second device not obtaining the first information, or that the first communication link was abnormal, resulting in the second device not obtaining the first information.

[0087] D2) For example, if the first information is determined to be abnormal information because the sampling results of some channels are inaccurate, the corresponding reason may be that some sampling channels corresponding to the first optical signal are abnormal.

[0088] As can be seen, the reasons why the first piece of information is identified as abnormal may be different, and different reasons will be associated with different processing procedures of the first piece of information in the first device. For example, the reason corresponding to A2) may be associated with the sampling process corresponding to the first piece of information, the reason corresponding to B2) may be associated with the sampling process or the communication process corresponding to the first piece of information, the reason corresponding to C2) may be associated with the sampling process or the communication process corresponding to the first piece of information, or the reason corresponding to D2) may be associated with the sampling process corresponding to the first piece of information, etc.

[0089] Therefore, during the process of the first device sending the second information, the reason why the first information was identified as abnormal information can be determined, and the mode of sending the second information can be determined based on the abnormality.

[0090] Figure 3A This is a flowchart illustrating a method for sending second information according to some embodiments of the present disclosure. Figure 1 .like Figure 3A As shown, the method includes the following steps S21 to S22-2.

[0091] In step S21, the reason why the first information is identified as abnormal information is determined.

[0092] In step S22-1, in response to the cause characterizing the first communication link as abnormal, second information is sent to the second device based on the second communication link.

[0093] In step S22-2, in response to the cause characterizing the first optical signal sampling abnormality, second information is sent to the second device based on the first communication link, or second information is sent to the second device based on the second communication link.

[0094] In this embodiment of the disclosure, by determining the reason why the first information is identified as abnormal information, the first device can associate the reason why the first information is identified as abnormal information with the process of sending the second information, thereby increasing the probability that the second information is successfully sent to the second device.

[0095] It is understandable that the cause of the first communication link being abnormal could be, for example, the second device being unable to report the sampled first data to the second device (i.e., some cases of B2 or C2 above). Therefore, for cases where the cause is the first communication link being abnormal, information can be reported using other communication links (e.g., based on the second communication link) (e.g., sending second information).

[0096] It is also understandable that the cause of the abnormal sampling of the first optical signal could be an anomaly in the sampling process corresponding to the first information (i.e., the situations described in A2 or D2 above). Therefore, in cases where the cause is an abnormal sampling of the first optical signal, other optical signals can be sampled (e.g., the second optical signal) to obtain the information to be reported to the second device (e.g., the second information). As for the selection of the communication link, the second information can be sent using either the first communication link or the second communication link.

[0097] For ease of understanding, the implementation scenarios corresponding to the above-mentioned related implementation methods will be illustrated below using 3B to 3D examples.

[0098] Figure 3BThis is a scenario illustration of a method for sending second information according to some embodiments of the present disclosure. Figure 1 .like Figure 3B As shown, continuing from the above Figure 2B Related examples and explanations, Figure 3B The corresponding scenario can be understood as a first communication link failure (e.g., indicated by "×" in the diagram). In the event of a first communication link failure, the first device can send second information to the second device via the second communication link. In this case, the corresponding signal flow path within the first device could be, for example, the first device controlling the second sampling unit to sample and process the second optical signal 1 and the second optical signal 2 to obtain the second information, and then sending the second information to the second communication unit. The first device then controls the second communication unit to send the second information to the second device via the second communication link.

[0099] Figure 3C This is a schematic diagram of a scenario illustrating a method for sending second information according to some embodiments of this disclosure. For example... Figure 3C As shown, continuing from the above Figure 2B Related examples and explanations, Figure 3C The corresponding scenario can be understood as a first optical signal sampling anomaly (e.g., an "×" in the diagram indicates a first sampling unit anomaly). In the event of a first optical signal sampling anomaly, the first device can send second information to the second device via the first communication link. In this case, the corresponding signal flow path in the first device could be, for example: the first device controls the second sampling unit to sample and process the second optical signal 1 and the second optical signal 2 to obtain the second information, and then sends the second information to the first communication unit. The first device then controls the first communication unit to send the second information to the second device via the first communication link. In some scenarios, the second sampling unit can also send information to the second communication unit (e.g., as indicated by the dashed line in the diagram).

[0100] Figure 3D This is a schematic diagram of a scenario illustrating a method for sending second information according to some embodiments of this disclosure. For example... Figure 3D As shown, continuing from the above Figure 2B Related examples and explanations, Figure 3DThe corresponding scenario can be understood as a first optical signal sampling anomaly (e.g., an "×" in the diagram indicates a first sampling unit anomaly). In the event of a first optical signal sampling anomaly, the first device can send second information to the second device via the second communication link. In this case, the corresponding signal flow path in the first device could be, for example, the first device controlling the second sampling unit to sample and process the second optical signal 1 and the second optical signal 2 to obtain the second information, and then sending the second information to the first communication unit. The first device then controls the first communication unit to send the second information to the second device via the first communication link. In some scenarios, the second sampling unit can also send information to the first communication unit (e.g., as indicated by the dashed line in the diagram).

[0101] Therefore, through the above-described implementation methods, the first device can send the second information to the second device based on a reason (e.g., the reason why the first information is determined to be abnormal information).

[0102] Based on the above-described embodiments, it is known that there may be multiple first optical signals, and some of the first optical signals may have sampling anomalies (i.e., the partial reasons shown in example C2 above). In this case, a portion of the second optical signals can be used as a backup to generate second information for transmission to the second device, and the second information can be transmitted to the second device.

[0103] Figure 4 This is a flowchart illustrating a method for sending second information according to some embodiments of the present disclosure. (See diagram 2.) Figure 4 As shown, the method includes the following steps S31 to S33. The number of first optical signals is N, the number of second optical signals is N, there is a first correspondence between the first and second optical signals, first information is carried based on N first optical signals, and second information is carried based on N second optical signals, where N is an integer greater than 1.

[0104] In step S31, M first optical signals with sampling abnormalities are determined from N first optical signals, and M backup optical signals are determined from the second optical signals based on the first correspondence.

[0105] In step S32, the second information is determined based on the third and fourth information.

[0106] In step S33, the second information is sent to the second device based on the first communication link, or the second information is sent to the second device based on the second communication link.

[0107] Among them, the backup optical signal is the second optical signal corresponding to the first optical signal with sampling error, and M is a positive integer less than or equal to N. The third information is the information carried by the first optical signal with normal sampling in the first optical signal, and the fourth information is the information carried by the M backup optical signals.

[0108] In this embodiment, since there is a correspondence between the first optical signal and the second optical signal, when an abnormally sampled optical signal is detected in the first optical signal, the optical signal corresponding to the abnormally sampled first optical signal (i.e., the backup optical signal) can be determined in the second optical signal. The backup optical signal is then sampled to obtain the information carried by the backup optical signal (i.e., the fourth information). The second information can then be determined based on the information carried by the normally sampled first optical signal (i.e., the third information) and the fourth information. This embodiment saves resource overhead in the optical signal sampling process and improves the efficiency of device processing compared to sampling all second optical signals to determine the second information.

[0109] The determination of the second information in the above embodiments can be achieved, for example, by the following: Figure 5 The implementation method shown is adopted. Figure 5 This is a flowchart illustrating a method for determining second information according to some embodiments of the present disclosure. Figure 5 As shown, the method includes the following steps S41 to S42. Wherein, N first optical signals correspond to N first channels, N second optical signals correspond to N second sampling channels, and there is a second correspondence between the N first sampling channels and the N second sampling channels.

[0110] In step S41, based on the first optical signal that is normally sampled in the first optical signal, M backup signals, the first correspondence and the second correspondence, the third information and the fourth information are spliced ​​together to obtain the spliced ​​information.

[0111] In step S42, the spliced ​​information is determined as the second information.

[0112] In this embodiment, since there is a second correspondence between the N first sampling channels and the N second sampling channels, and the optical signal (e.g., the first optical signal or the second optical signal) is associated with the sampling channel (e.g., the first sampling channel or the second sampling channel), the determination of the second information can be achieved in the dimension of sampling association.

[0113] To facilitate understanding, the following will be explained... Figure 6A to Figure 6B The scenario shown illustrates the above-described related implementation methods.

[0114] Figure 6AThis is a schematic diagram of a scenario illustrating a method for determining second information according to some embodiments of the present disclosure.

[0115] like Figure 6A As shown, continuing the description of the aforementioned related implementation examples, the first sampling unit of the first device is provided with two independent sampling channels (e.g., the first sampling channel 1 for sampling the first optical signal 1 and the first sampling channel 2 for sampling the first optical signal 2 in the figure), and a first demodulation unit (for demodulating the sampled signal and integrating and splicing the demodulated information to obtain the first information). The second sampling unit of the first device is provided with two independent sampling channels (e.g., the second sampling channel 1 for sampling the second optical signal 1 and the second sampling channel 2 for sampling the second optical signal 2), and a second demodulation unit (for demodulating the sampled signal and integrating and splicing the demodulated information to obtain the second information).

[0116] exist Figure 6A In the scenario described, assuming the first sampling channel 1 malfunctions, causing the information carried by the first optical signal 1 in the first information to be incorrect, the information carried by the first optical signal 2 can be referred to as the third information, for example. Furthermore, based on the first correspondence, the first device can determine that the backup signal corresponding to the first optical signal 1 is the second optical signal 1. Therefore, in this case, the first device can sample the second optical signal 1 based on the second sampling channel 1 and demodulate the sampled signal based on the second demodulation unit to obtain the fourth information.

[0117] The first device can obtain the second information, for example, through the following method A3) or B3):

[0118] A3) The first device can control the second demodulation unit to send the fourth information to the first demodulation unit, and splice (or integrate) the third and fourth information based on the first demodulation unit to obtain the second information.

[0119] B3) The first device can also control the first demodulation unit to send the third information to the second demodulation unit, and splice (or integrate) the third information and the fourth information based on the second demodulation unit to obtain the second information.

[0120] If the first device obtains the fourth information, it can be done, for example, as follows: Figure 6B The scenario shown sends a second message. Figure 6B This is a schematic diagram illustrating a scenario of a method for sending second information according to some embodiments of this disclosure. For example... Figure 6BAs shown, the first device, for example, can control the demodulation unit (e.g., the first demodulation unit or the second demodulation unit) to send second information to the communication unit (e.g., the first communication unit or the second communication unit) in at least one of the following methods (A3-1) to B3-2), so as to send the second information based on the corresponding communication link (e.g., the first communication link or the second communication link):

[0121] A3-1) The first device controls the first demodulation unit to send the second information to the first communication unit, so that the first device sends the second information based on the first communication link.

[0122] A3-2) The first device controls the first demodulation unit to send the second information to the second communication unit, so that the first device sends the second information based on the second communication link.

[0123] B3-1) The first device controls the second demodulation unit to send the second information to the first communication unit, so that the first device sends the second information based on the first communication link.

[0124] B3-2) The first device controls the second demodulation unit to send the second information to the second communication unit, so that the first device sends the second information based on the second communication link.

[0125] As can be seen, in the above scenario, there is a communication interaction relationship between the demodulation unit (e.g., the first demodulation unit or the second demodulation unit) and the communication unit (e.g., the first communication unit or the second communication unit).

[0126] In some implementations, to achieve communication interaction between the demodulation unit and the communication unit, it can be achieved, for example, in the following manner: A4) or B4)

[0127] A4) Integrating the demodulation unit and the communication unit into the same chip (or module) to achieve communication interaction between the demodulation unit and the communication unit simplifies the module design.

[0128] For example, in some scenarios, the first demodulation unit and the first communication unit can be integrated into the same chip (or module).

[0129] For example, in some scenarios, the second demodulation unit and the second communication unit can be integrated into the same chip (or module).

[0130] B4) By setting up a corresponding interface or serializer between the demodulation unit and the communication unit, communication interaction between the demodulation unit and the communication unit can be realized.

[0131] It should be noted that the selection of the corresponding interface or serializer can be based on the actual use case (e.g., based on the throughput to be transmitted in the scenario).

[0132] Therefore, through the above-described implementation methods, the first device can send the second information when the first information is determined to be abnormal.

[0133] It is also understandable that, based on the examples A2) to D2) above, the first information is determined to be abnormal. The reason for this determination may be related to the first communication link (e.g., some examples in B2 or D2). In this case, the first information sampling process may be normal. Therefore, in this situation, the first device can send the first information based on a communication link other than the first communication link.

[0134] For example, in some implementations, if the first information is determined to be abnormal, the first device may also send the first information to the second device based on the second communication link.

[0135] For example, when the first device sends first information to the second device, it can be done through... Figure 7 The implementation method shown is adopted. Figure 7 This is a flowchart illustrating a method for sending first information according to some embodiments of the present disclosure. Figure 7 As shown, the method includes the following steps S51 to S52.

[0136] In step S51, the reason why the first information was identified as abnormal information is determined.

[0137] In step S52, in response to the cause indicating an anomaly in the first communication link, first information is sent to the second device based on the second communication link.

[0138] It is understandable that the methods for determining the cause have been described similarly in the above-mentioned related implementation methods, and will not be repeated here.

[0139] Therefore, through such Figure 7 The implementation shown allows the first device to achieve communication and interaction with the second device by retransmitting the first information.

[0140] In summary, the above-described implementation methods can enhance the reliability of communication between optical sensing devices in special scenarios.

[0141] Based on the same concept, this disclosure also proposes a communication method for use in a second device.

[0142] Figure 8 This is a schematic flowchart illustrating a communication method according to some embodiments of the present disclosure. Figure 8As shown, the method is applied to the second device and includes the following steps S61 to S63.

[0143] In step S61, the first information sent by the first device based on the first communication link is obtained.

[0144] In step S62, if the first information is abnormal, feedback information is sent to the first device.

[0145] In step S63, the second information is obtained.

[0146] The first device includes an underwater electronic device. The first information is the information carried by a first optical signal, which is obtained by sampling the first optical signal. The first optical signal is obtained by splitting the input optical signal by the first device. The first information carried by the first optical signal is the same as the information carried by the input optical signal. Feedback information is used to characterize why the first information is determined to be abnormal. The second information is sent by the first device based on a first communication link, or by the first device based on a second communication link, where the first and second communication links are different. The second information is the information carried by a second optical signal, which is obtained by sampling the second optical signal. The second optical signal is obtained by splitting the input optical signal by the first device. The second information carried by the second optical signal is the same as the information carried by the input optical signal.

[0147] Understandably, for Figure 8 In the implementation method, the interpretation and implementation of relevant features are described above. Figure 2A to Figure 7 The relevant implementation methods have been described in detail and will not be repeated here.

[0148] In some implementations, after the second device sends feedback information to the first device, it can also obtain the first information sent by the first device based on the second communication link.

[0149] In the embodiments disclosed herein, some or all of the steps and their optional implementation methods can be arbitrarily combined with some or all of the steps in other embodiments, or can be arbitrarily combined with the optional implementation methods in other embodiments.

[0150] In summary, the above-described implementation methods can enhance the reliability of communication between optical sensing devices in special scenarios.

[0151] Based on the same concept, this disclosure also proposes an apparatus for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the first device in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by the second device in any of the above methods.

[0152] It is understood that the apparatus provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. By combining the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software.

Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solution of this disclosure.

[0153] Figure 9A This is a block diagram illustrating a communication device 100 according to some embodiments of the present disclosure. The communication device 100 is applied to a first device, such as... Figure 9A As shown, the communication device 100 includes:

[0154] The processing unit 101 is used to split the acquired input optical signal into a first optical signal and a second optical signal, wherein the first information carried by the first optical signal is the same as the information carried by the input optical signal, and the second information carried by the second optical signal is the same as the information carried by the input optical signal.

[0155] The transceiver unit 102 is used to send first information to the second device based on the first communication link, wherein the first information is obtained by the first device sampling the first optical signal, and the first device includes an electronic device installed underwater;

[0156] If the first information is determined to be abnormal, a second information is sent to the second device based on the first communication link, or a second information is sent to the second device based on the second communication link, wherein the second information is obtained by the first device sampling the second optical signal, and the second communication link is different from the first communication link.

[0157] In some implementations, the transceiver unit 102 sends second information to the second device via the first communication link or via the second communication link in the following manner: determining the reason why the first information is determined to be abnormal information; in response to the reason indicating an abnormality in the first communication link, sending second information to the second device via the second communication link; in response to the reason indicating an abnormality in the sampling of the first optical signal, sending second information to the second device via the first communication link or via the second communication link.

[0158] In some implementations, the number of first optical signals is N, the number of second optical signals is N, and there is a first correspondence between the first optical signals and the second optical signals. First information is carried based on N first optical signals, and second information is carried based on N second optical signals, where N is an integer greater than 1. When the cause indicates that the first optical signal sampling is abnormal, the transceiver unit 102 sends the second information to the second device based on the first communication link or sends the second information to the second device based on the second communication link in the following manner: M first optical signals with abnormal sampling are determined from the N first optical signals, and M backup optical signals are determined from the second optical signals based on the first correspondence, where the backup optical signals are the second optical signals corresponding to the first optical signals with abnormal sampling, and M is a positive integer less than or equal to N; the second information is determined based on the third information and the fourth information, where the third information is the information carried by the first optical signals with normal sampling, and the fourth information is the information carried by the M backup optical signals; the second information is sent to the second device based on the first communication link or the second communication link.

[0159] In some implementations, N first optical signals correspond to N first channels, N second optical signals correspond to N second sampling channels, and there is a second correspondence between the N first sampling channels and the N second sampling channels. The transceiver unit 102 determines the second information based on the third and fourth information in the following manner: based on the first optical signal that is normally sampled in the first optical signal, M backup signals, the first correspondence, and the second correspondence, the third and fourth information are spliced ​​together to obtain the spliced ​​information; the spliced ​​information is determined as the second information.

[0160] In some implementations, if the first information is determined to be abnormal information, the transceiver unit 102 is further configured to: send the first information to the second device based on the second communication link.

[0161] In some implementations, the transceiver unit 102 sends first information to the second device via the second communication link in the following manner: determining the reason why the first information is identified as abnormal information; in response to the reason indicating that the first communication link is abnormal, sending the first information to the second device via the second communication link.

[0165] In some scenarios, the transceiver unit 102 may have some of the functions of the processing unit 101 (e.g., determining data and / or information, or processing data and / or information). In other scenarios, the processing unit 101 may have some of the functions of the transceiver unit 102 (e.g., sending information and / or signals, or receiving information and / or signals), which will not be elaborated here.

[0166] Based on the same concept, this disclosure also proposes a communication device.

[0167] Figure 9B This is a block diagram illustrating a communication device 110 according to some embodiments of the present disclosure. The communication device 110 is applied to a second device, such as... Figure 9B As shown, the communication device 110 includes:

[0168] The transceiver unit 111 is configured to acquire first information transmitted by a first device via a first communication link, wherein the first device includes an electronic device disposed underwater, the first information is information carried by a first optical signal, the first information is obtained by the first device sampling the first optical signal, the first optical signal is obtained by the first device splitting the input optical signal, and the first information carried by the first optical signal is the same as the information carried by the input optical signal; and is configured to send feedback information to the first device if the first information is abnormal information, wherein the feedback information is used to characterize the reason why the first information is determined to be abnormal information; and is configured to acquire second information, wherein the second information is transmitted by the first device via the first communication link, or the second information is transmitted by the first device via a second communication link, the first communication link and the second communication link are different, the second information is information carried by a second optical signal, the second information is obtained by the first device sampling the second optical signal, the second optical signal is obtained by the first device splitting the input optical signal, and the second information carried by the second optical signal is the same as the information carried by the input optical signal.

[0169] In some implementations, the transceiver unit 111 is also used to acquire first information sent by the first device based on the second communication link.

[0170] It should be noted that in the above-described embodiments, the transceiver unit 102 may include a transmitting unit and / or a receiving unit. The transmitting unit and the receiving unit may be separate or integrated together. Optionally, the transceiver unit 102 may be interchangeable with a transceiver.

[0171] It should also be noted that in the above-mentioned embodiments, the communication device 110 may further include a processing unit. The processing unit may be used to perform at least one of the communication steps such as sending and / or receiving performed by the communication device 110 in any of the above methods, or to perform related steps such as information processing, which will not be elaborated here.

[0172] In some scenarios, the transceiver unit 102 may have some of the functions of the processing unit (e.g., determining data and / or information, or processing data and / or information). In other scenarios, the processing unit may have some of the functions of the transceiver unit 111 (e.g., sending information and / or signals, or receiving information and / or signals), which will not be elaborated here.

[0173] Based on the same concept, this disclosure also proposes a communication system, which includes a first device and a second device.

[0174] Figure 10 This is a schematic diagram illustrating the communication interaction of a communication system according to some embodiments of this disclosure. For example... Figure 10 As shown, the communication system may be, for example, a communication system including a first device and a second device, wherein the first device includes an electronic device disposed underwater. The communication interaction between the first device and the second device includes, for example, the following steps S71 to S74.

[0175] In step S71, the first device splits the acquired input optical signal to obtain a first optical signal and a second optical signal.

[0176] In step S72, the first device sends first information to the second device based on the first communication link.

[0177] In step S73, if the first information is abnormal, the second device sends feedback information to the first device.

[0178] In step S74, the first device sends second information to the second device based on the first communication link or the second communication link.

[0179] In this system, the first information carried by the first optical signal is the same as the information carried by the input optical signal, and the second information carried by the second optical signal is the same as the information carried by the input optical signal. The first information is obtained by sampling the first optical signal by the first device. Feedback information is used to characterize why the first information is determined to be abnormal.

[0180] It is understood that, based on the above description of the relevant implementation methods, the communication interaction between the first device and the second device may include, for example, the interaction between the second device and the communication unit of the first device (e.g., the first communication unit and / or the second communication unit).

[0181] In some implementation scenarios, the communication units of the second device and the first device can interact via fiber optic cables or network cables. In this scenario (e.g., where the two communicate via optical signals), to ensure the reliability of the communication interaction, a corresponding beam splitting unit can be added to the communication architecture to split the optical signal carrying information (e.g., feedback information) sent by the second device, obtaining a first feedback optical signal and a second feedback optical signal. The first feedback optical signal and the second feedback optical signal are then sent to the communication unit of the first device via their respective communication links (e.g., the first feedback optical signal is sent to the first communication unit via the first communication link, and the second feedback optical signal is sent to the second communication unit via the second communication link, etc.).

[0182] In other implementation scenarios, the communication units of the second device and the first device can interact via fiber optic cables or network cables. In this scenario (e.g., where the two communicate via optical signals), to ensure the reliability of the communication interaction, a corresponding integration unit can be added to the communication architecture. This unit monitors and integrates the information sent by the first communication unit (first information and / or second information) and the information sent by the second communication unit (first information and / or second information). The acquired information is then integrated (e.g., the first information and / or second information are integrated based on first and second relationships to reduce the possibility of missing or duplicate information corresponding to some sampling channels in the transmitted information) before being sent to the second device.

[0183] It should be noted that in some embodiments of this disclosure, the apparatus and equipment can be interpreted as physical or virtual, and their names are not limited to the names recorded in the examples of "device", "system" and "network". In some cases, they can also be understood as "equipment", "circuit", "network element", "node", "function", "unit", "section", "chip", "chip system", "entity", "body", etc.

[0184] Based on the same concept, this disclosure also proposes a communication device.

[0185] Figure 11 This is a schematic diagram of an electronic device provided for an embodiment of this application.

[0186] In some embodiments, the electronic device may include one or more processors and a memory coupled to the processor. The memory is configured to store one or more computer programs. The computer program code includes computer instructions that, when executed by the processor, cause the electronic device to perform the methods described above.

[0187] like Figure 11 As shown, the electronic device 200 includes a processor 201 and a memory 202. Exemplarily, the electronic device 200 may also include a communications interface 203 and a communications bus 204.

[0188] The processor 201, memory 202, and communication interface 203 communicate with each other via communication bus 204. Communication interface 203 is used to communicate with other network elements such as clients or other servers.

[0189] In some embodiments, the processor 201 is used to execute the computer program 205, specifically performing the relevant steps in the above-described communication method embodiments. Specifically, the computer program 205 may include computer program code, which includes computer-executable instructions.

[0190] For example, processor 201 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), or one or more integrated circuits configured to implement some embodiments of this application. Electronic device 200 may include one or more processors, which may be processors of the same type, such as one or more CPUs; or processors of different types, such as one or more CPUs and one or more ASICs.

[0191] In some implementations, memory 202 is used to store computer program 205. Memory 202 may include high-speed RAM memory, and may also include non-volatile memory (NVM), such as at least one disk storage device.

[0192] The computer program 205 can be called by the processor 201 to cause the electronic device 200 to perform operations based on the above method.

[0193] In some embodiments of this application, a computer-readable storage medium is also provided, which stores at least one executable instruction that, when executed on an electronic device 200, causes the electronic device 200 to perform the communication method described in the above embodiments.
