[0023] Furthermore, a current transmission stability assessment is performed, and after the current transmission stability assessment is qualified, an electrical interface interference assessment of the optical fiber transceiver is performed. The specific process is as follows: if the number of partial discharges obtained is greater than the preset number of discharges obtained from the database, a current transmission instability prompt is sent, and the electrical interface interference assessment of the optical fiber transceiver is not performed; if the number of partial discharges obtained is not greater than the preset number of discharges, a current transmission stability prompt is sent, the electrical interface interference assessment of the optical fiber transceiver is performed, and the corresponding number of partial discharges is marked as qualified discharge number; the average value of the number of discharges at the preset transmission wire monitoring point in the preset time period is monitored by a discharge detector as the number of partial discharges, which is used to reflect the degree of qualification of the current transmission stability assessment; the current transmission stability assessment is used to reflect the stability of the wire current transmission during the automated production monitoring process of the optical fiber transceiver; the electrical interface interference assessment of the optical fiber transceiver is used to reflect the degree of distortion of the electrical interface signal of the optical fiber transceiver.

[0024] Specifically, the specific process of evaluating the electrical interface interference of the optical fiber transceiver is as follows: after quantifying the degree of approach between the qualified discharge number and the preset qualified discharge number, a weighted operation is performed in combination with the preset qualified discharge-control value to obtain a qualified discharge-interference observation value, which is used to reflect the effect of the qualified discharge number on the degree of signal distortion of the electrical interface of the optical fiber transceiver. In this application, the quantification of the degree of approach means performing a ratio operation; specifically, the expression of the qualified discharge-interference observation value is: , , V represents the number of the preset electrical interface interference assessment time period, T represents the total number of preset electrical interface interference assessment time periods, represents the qualified discharge-interference observation value of the Vth preset electrical interface interference assessment time period, Indicates the number of qualified discharges in the Vth preset electrical interface interference assessment time period, Indicates the preset qualified discharge times, Indicates the preset qualified discharge-control value. Both the preset qualified discharge number and the qualified discharge number have no units.

[0025] After quantifying the degree of convergence between the spatial radiation electromagnetic noise intensity and the preset spatial radiation electromagnetic noise intensity, a weighted operation is performed on the preset spatial noise-control value to obtain the spatial noise-interference observation value, which is used to reflect the effect of the spatial radiation electromagnetic noise intensity on the degree of signal distortion of the electrical interface of the optical fiber transceiver. Specifically, the expression of the spatial noise-interference observation value is: , represents the spatial noise-interference observation value of the Vth preset electrical interface interference assessment time period, Indicates the spatial radiation electromagnetic noise intensity during the Vth preset electrical interface interference assessment period, Indicates the intensity of electromagnetic noise radiated in the preset space. Indicates the preset spatial noise control value. An optical phase analyzer monitors the maximum and minimum phase values ​​of the optical signal during the preset electrical interface interference assessment period. The difference between the maximum and minimum phase values ​​is used as the optical signal phase fluctuation deviation. The unit of the spatial radiated electromagnetic noise intensity and the preset spatial radiated electromagnetic noise intensity is mA / m.

[0026] After quantifying the degree of convergence between the optical signal phase fluctuation deviation and the preset optical signal phase fluctuation deviation, a weighted operation is performed on the preset phase fluctuation-control value to obtain a phase fluctuation-interference observation value, which is used to reflect the effect of the optical signal phase fluctuation deviation on the degree of signal distortion of the electrical interface of the optical fiber transceiver. Specifically, the expression of the phase fluctuation-interference observation value is: , represents the phase fluctuation-interference observation value of the Vth preset electrical interface interference assessment time period, Indicates the optical signal phase fluctuation deviation in the Vth preset electrical interface interference assessment time period, Indicates the preset optical signal phase fluctuation deviation, Indicates the preset phase fluctuation control value. A spectrum analyzer and an electromagnetic field strength probe are used to monitor the electromagnetic field intensity of spatial radiation within a preset frequency band during the preset electrical interface interference assessment period. The maximum value is used as the spatial radiation electromagnetic noise intensity. The units of the optical signal phase fluctuation deviation and the preset optical signal phase fluctuation deviation are both degrees.

[0027] The electrical interface interference assessment quantification value is obtained by coupling the electrical interface interference assessment quantification data; the electrical interface interference assessment quantification value is used to reflect the combined effect of the electrical interface interference assessment quantification parameter and the preset electrical interface interference assessment quantification parameter on the degree of electrical interface signal distortion of the optical fiber transceiver.

[0028] The quantified value of the electrical interface interference evaluation is obtained by the following method: ; Where, Represents the electrical interface interference assessment quantization value of the Vth preset electrical interface interference assessment time period.

[0029] The quantitative data of the electrical interface interference assessment include qualified discharge-interference observation values, spatial noise-interference observation values ​​and phase fluctuation-interference observation values; the quantitative parameters of the electrical interface interference assessment include the number of qualified discharges, the intensity of spatial radiation electromagnetic noise and the phase fluctuation deviation of the optical signal; the preset quantitative parameters of the electrical interface interference assessment include the preset number of qualified discharges, the preset intensity of spatial radiation electromagnetic noise and the preset phase fluctuation deviation of the optical signal; the preset electrical interface interference assessment time period represents the preset time period in the process of performing the electrical interface interference assessment of the optical fiber transceiver.

[0030] Among them, before the design of the fiber optic transceiver monitoring method based on the Internet of Things provided in the present application, a database for storing various setting data is established, which includes but is not limited to a preset qualified discharge number, a preset spatial radiation electromagnetic noise intensity, and a preset optical signal phase fluctuation deviation, etc., and the various values ​​are directly set by technical personnel; for example, the preset discharge number is represented by the average value of the local discharge number in the historical time period; the preset electrical interface interference assessment quantization parameter is represented by the average value of the electrical interface interference assessment quantization parameter in the historical time period; the embodiment of the present application provides a set of mapping relationships for reflecting the electrical interface interference assessment quantization parameters and corresponding preset electrical interface interference adjustment values, and a mapping group containing a mapping set, which is obtained from a database and contains a mapping group containing a mapping set, wherein the mapping relationship in the mapping set can be a one-to-one correspondence or a many-to-one relationship. Through the preset mapping relationship set by the preset personnel, the electrical interface interference assessment quantization parameters and the preset electrical interface interference adjustment values ​​are matched one-to-one or many-to-one to obtain a mapping group; by inputting the real-time electrical interface interference assessment quantization parameter into the corresponding mapping group, the corresponding preset electrical interface interference adjustment value can be obtained; the value range of the preset electrical interface interference adjustment value is 0-1. The preset electrical interface interference adjustment value includes a preset qualified discharge-control value, a preset spatial noise-control value and a preset phase fluctuation-control value, which are used to reflect the influence of the electrical interface interference evaluation quantization parameters on the electrical interface interference evaluation quantization data.

[0031] In this embodiment, the electrical interface interference assessment quantification value is further obtained by quantifying the degree of electrical interface signal distortion of the electrical interface interference assessment quantification data. A larger electrical interface interference assessment quantification value indicates a greater effect of the number of qualified discharges on the degree of electrical interface signal distortion of the optical fiber transceiver, a greater effect of the intensity of spatially radiated electromagnetic noise on the degree of electrical interface signal distortion of the optical fiber transceiver, and a greater effect of the optical signal phase fluctuation deviation on the degree of electrical interface signal distortion of the optical fiber transceiver, resulting in a larger electrical interface interference assessment quantification value. In summary, in this embodiment, the electrical interface interference assessment quantification data and the electrical interface interference assessment quantification value are positively correlated.

[0032] The electrical interface interference evaluation quantitative parameters monitored in the embodiment are not isolated, but have mutual correlation characteristics that need to be analyzed to describe their joint action. The more the number of qualified discharges, the greater the possibility of unstable current transmission, the greater the possibility of more electromagnetic pulses and electromagnetic radiation superimposed on the electrical interface to cause signal distortion, and the greater the intensity of spatial radiation electromagnetic noise; the more the number of qualified discharges, the more the electromagnetic pulses generated by the discharge may cause changes in the optical properties of the transmission medium in the optical fiber, thereby causing phase fluctuations in the optical signal during transmission, and the greater the optical signal phase fluctuation deviation; the greater the intensity of spatial radiation electromagnetic noise, the high-frequency components in the electromagnetic noise may interact with the optical signal, causing random changes in the phase of the optical signal, thereby increasing the optical signal phase fluctuation deviation. By analyzing the comprehensive influence between the parameters, the accuracy of the electrical interface signal distortion degree is evaluated, and the accuracy of the monitoring result of the optical fiber transceiver for optical signal conversion is improved.

[0033] Further, based on the optical signal conversion accuracy evaluation result, it is judged whether to perform optical signal conversion optimization, and the specific process is as follows: based on the electrical interface interference evaluation quantitative value, it is judged whether to perform optical fiber transceiver electrical interface optimization; if the obtained electrical interface interference evaluation quantitative value is greater than the preset electrical interface interference value obtained from the database, an electrical interface evaluation unqualified prompt is sent, i.e. optical fiber transceiver electrical interface optimization is needed to improve the accuracy of optical signal conversion, wherein the preset electrical interface interference value is represented by the average value of the historical period interface interference evaluation quantitative value; if the obtained electrical interface interference evaluation quantitative value is not greater than the preset electrical interface interference value obtained from the database, an electrical interface evaluation qualified prompt is sent, and the accuracy of optical signal conversion is evaluated.

[0034] Among them, the specific process of optimizing the electrical interface of the optical fiber transceiver is as follows: the first step is to perform redundant channel diversion; performing redundant channel diversion means sending a prompt to the preset personnel, and switching to the backup optical fiber link for data diversion when an unqualified interface interference assessment quantization value is detected; the unqualified interface interference assessment quantization value represents an electrical interface interference assessment quantization value that is greater than the preset electrical interface interference value obtained from the database; performing redundant channel diversion is used to avoid communication interruption caused by single point failure to improve the eligibility of redundant verification; the second step is to perform redundant verification; based on the unqualified interface interference assessment quantization value and the coding gain, redundant correction is performed to obtain a preset redundant adjustment ratio; redundant correction means inputting the unqualified interface interference assessment quantization value and the coding gain into the preset forward error correction correction set to obtain the preset redundant adjustment ratio to correct the redundant verification adjustment ratio; judging whether the preset redundant adjustment ratio is not greater than the preset maximum redundant adjustment ratio ; If the preset redundancy adjustment ratio is not greater than the preset maximum redundancy adjustment ratio, the corresponding preset redundancy adjustment ratio will be marked as qualified redundancy adjustment, otherwise an alarm prompt will be sent, wherein the preset maximum redundancy adjustment ratio is set in advance by the preset personnel; a prompt will be sent to the preset personnel to gradually increase the redundant check bit by the amplitude corresponding to the qualified redundancy adjustment ratio; if the redundant bit is increased to the preset maximum redundancy check bit, the electrical interface interference assessment quantization value is still greater than the preset electrical interface interference value obtained from the database, an alarm prompt will be sent, wherein the preset maximum redundancy check bit is set in advance by the preset personnel; if the electrical interface interference assessment quantization value obtained again after the optical fiber transceiver electrical interface optimization is not greater than the preset electrical interface interference value obtained from the database, the optical fiber transceiver electrical interface optimization qualified monitoring will be performed; the preset forward error correction correction set is used to reflect the correction relationship between the unqualified interface interference assessment quantization value and coding gain and the corresponding preset redundancy adjustment ratio.

[0035] In this embodiment, when a prompt for optimizing the electrical interface of the optical fiber transceiver is received, data is first switched to the backup optical fiber link through redundant channel diversion, which can ensure the continuity of optical signal transmission, avoid communication interruption due to single point failure, and help reduce data loss due to link failure, thereby improving the accuracy of redundancy check; when a prompt for redundancy check is received, the redundant check bits are gradually increased by an amplitude corresponding to the qualified redundancy adjustment ratio. The redundant check bits can correct errors in the optical signal transmission process, which helps to reduce signal damage caused by signal distortion interference; by controlling the preset redundancy adjustment ratio to be no greater than the preset maximum redundancy adjustment ratio, it helps to avoid increased transmission delay due to excessive redundancy while ensuring data transmission quality. By controlling the redundant bits to be no greater than the preset maximum redundant check bits, it helps to improve the qualification of the redundancy check; thereby achieving the effect of improving the accuracy of the monitoring results of optical signal conversion performed by the optical fiber transceiver.

[0036] Further, the optical fiber transceiver electrical interface optimization qualified monitoring is performed, and the specific process is as follows: if the obtained electrical interface optimization qualified value is within the preset electrical interface optimization qualified range obtained from the database, an optical fiber transceiver electrical interface optimization qualified prompt is sent, and optical signal conversion accuracy evaluation is performed; if the obtained electrical interface optimization qualified value is not within the preset electrical interface optimization qualified range obtained from the database, an alarm prompt is sent; the electrical interface optimization qualified value is represented by the absolute value of the difference between the electrical interface interference evaluation quantitative value in the final state of the optical fiber transceiver electrical interface optimization and the electrical interface interference evaluation quantitative value in the initial state of the optical fiber transceiver electrical interface optimization; the electrical interface optimization qualified value is used to reflect the qualified degree of the optical fiber transceiver electrical interface optimization; the optical signal conversion accuracy evaluation is used to reflect the accuracy of the optical signal conversion of the optical fiber transceiver, wherein the preset electrical interface optimization qualified range is set in advance by preset personnel, and the preset electrical interface optimization qualified range includes the end points of the upper and lower limits corresponding to the range.

The qualified electrical interface interference assessment quantitative value represents the electrical interface interference assessment quantitative value that is not greater than the preset electrical interface interference value obtained from the database, and only considers the case where the qualified electrical interface interference assessment quantitative value is greater than 0.

[0041] Optical signal conversion coupling quantization refers to coupling the optical signal conversion accuracy data to obtain the optical signal conversion accuracy quantization value of the optical transceiver; the optical signal conversion accuracy quantization value of the optical transceiver is used to reflect the effect of the optical signal conversion accuracy parameters of the optical transceiver and the preset optical signal conversion accuracy parameters of the optical transceiver on the accuracy of the optical signal converted by the optical transceiver.

[0042] The accurate quantization value of the optical signal conversion of the fiber optic transceiver is obtained by the following method: ; Where, Indicates the accurate quantized value of the optical signal conversion of the optical fiber transceiver in the Qth preset optical signal conversion time period.

[0044] Among them, the preset optical signal conversion accurate parameter of the optical fiber transceiver is represented by the average value of the optical signal conversion accurate parameter of the optical fiber transceiver in the historical time period; the embodiment of the present application provides a mapping group for reflecting the mapping relationship between the optical signal conversion accurate parameter of the optical fiber transceiver and the corresponding preset optical signal conversion adjustment value of the optical fiber transceiver, and contains a mapping set, which is obtained from a database and contains a mapping group of mapping sets, wherein the mapping relationship in the mapping set can be a one-to-one correspondence or a many-to-one relationship. Through the preset mapping relationship set by the preset personnel, the optical signal conversion accurate parameter of the optical fiber transceiver and the preset optical signal conversion adjustment value of the optical fiber transceiver are obtained in a one-to-one correspondence or a many-to-one correspondence; by inputting the real-time optical signal conversion accurate parameter of the optical fiber transceiver into the corresponding mapping group, the corresponding preset optical signal conversion adjustment value of the optical fiber transceiver can be obtained; the value range of the preset optical signal conversion adjustment value of the preset optical fiber transceiver is 0-1.

The larger the average optical signal jitter deviation, the greater the fluctuation in the time it takes for the optical signal to reach the receiving end, which may affect the decoding process and reduce the accuracy of the decoded signal; the larger the average transmitted optical power deviation, the more likely it is that the intensity of the optical signal received by the receiving end will be unstable, and the decoding circuit may not be able to accurately identify the signal, resulting in a decrease in the accuracy of the decoded signal; the larger the quantitative value of the qualified electrical interface interference assessment, the greater the degree of distortion of the electrical interface signal, which may affect the quality of the optical signal and reduce the accuracy of the decoded signal; the larger the average transmitted optical power deviation, the more likely it is that the nonlinear effect of the optical signal in the optical fiber will be caused, resulting in increased optical signal jitter, and thus a larger average optical signal jitter deviation. By analyzing the comprehensive impact of the parameters, an accurate assessment of the accuracy of the optical signal conversion by the fiber optic transceiver is achieved.

[0048] Furthermore, the specific process of determining whether to perform optical signal conversion optimization based on the optical signal conversion accuracy evaluation result is as follows: comparing the optical signal conversion accuracy quantization value of the optical fiber transceiver with the preset optical signal conversion value of the optical fiber transceiver obtained from the database, wherein the preset optical signal conversion value of the optical fiber transceiver is represented by the average value of the optical signal conversion accuracy quantization value of the optical fiber transceiver in the historical time period; if the obtained optical signal conversion accuracy quantization value of the optical fiber transceiver is greater than the preset optical signal conversion value of the optical fiber transceiver, a prompt indicating that the optical signal conversion of the optical fiber transceiver is qualified is sent, and the optical fiber transmission accuracy evaluation is performed; if the obtained optical signal conversion accuracy quantization value of the optical fiber transceiver is not greater than the preset optical signal conversion value of the optical fiber transceiver, a prompt indicating that the optical signal conversion of the optical fiber transceiver is unqualified is sent, and optical signal conversion optimization is performed; the optical fiber transmission accuracy evaluation is performed to reflect the accuracy of optical fiber line transmission.

[0049] Among them, the specific process of optimizing optical signal conversion is as follows: Step 1, perform pre-distortion setting; performing pre-distortion setting means sending a prompt to the preset personnel to pre-process the signal at the transmitting end of the optical fiber transceiver based on the pre-distortion method to reduce the nonlinear distortion in optical fiber transmission; Step 2, perform transimpedance amplification setting; performing transimpedance amplification setting means sending a prompt to the preset personnel to gradually increase the amplification factor of the transimpedance amplifier with the amplitude corresponding to the qualified amplification ratio; the qualified amplification ratio means a preset transimpedance ratio that is not greater than the preset maximum transimpedance ratio, wherein the preset maximum transimpedance ratio is set in advance by the preset personnel; the preset transimpedance ratio is obtained by amplifying and correcting the accurate quantization value of the optical signal conversion of the optical fiber transceiver and the transimpedance gain; the amplification correction means that the optical fiber transceiver The signal conversion accurate quantization value and transimpedance gain are input into the preset transimpedance amplification correction set obtained from the database to obtain the preset transimpedance ratio to correct the amplification ratio set by the transimpedance amplification factor; the preset transimpedance amplification correction set is used to reflect the correction relationship between the optical signal conversion accurate quantization value and transimpedance gain of the optical fiber transceiver and the corresponding preset transimpedance ratio; if the optical signal conversion accurate quantization value of the optical fiber transceiver is still not greater than the preset optical signal conversion value of the optical fiber transceiver when the amplification factor is increased to the preset maximum transimpedance factor, an alarm is sent, wherein the preset maximum transimpedance factor is set in advance by the preset personnel; if the optical signal conversion accurate quantization value of the optical fiber transceiver obtained again after the optical signal conversion optimization is greater than the preset optical signal conversion value of the optical fiber transceiver, the optical signal conversion optimization qualification monitoring is performed.

[0050] In the embodiment, when receiving the light signal conversion optimization prompt, the optical signal is preprocessed at the transmitting end of the fiber transceiver by the pre-distortion method, so that the signal can be closer to the original signal after transmission through the optical fiber, thereby reducing the nonlinear distortion in the optical fiber transmission, and helping the optical signal to be more accurately restored at the receiving end; by gradually increasing the amplification multiple of the transimpedance amplifier corresponding to the qualified amplification ratio, the signal strength in the transmission process can be ensured, and the influence of signal attenuation can be reduced; by controlling the preset transimpedance ratio to be not greater than the preset maximum transimpedance ratio, signal distortion in the amplification process of the transimpedance amplifier can be avoided; by controlling the amplification multiple to be not greater than the preset maximum transimpedance multiple, the best state of the optical fiber transmission can be ensured; and the accuracy of the monitoring result of the optical signal conversion of the fiber transceiver is improved.

[0051] Further, the specific process of the optical signal conversion optimization eligibility monitoring is as follows: obtaining the optical signal conversion optimization eligibility value; comparing the optical signal conversion optimization eligibility value and the preset optical signal conversion optimization range obtained from the database, wherein the preset optical signal conversion optimization range is set in advance by the preset personnel, and the preset optical signal conversion optimization range contains the end points of the upper and lower limits corresponding to the range; if the obtained optical signal conversion optimization eligibility value is within the preset optical signal conversion optimization range obtained from the database, the optical signal conversion optimization eligibility prompt is sent, and the optical fiber transmission accuracy is evaluated; if the obtained optical signal conversion optimization eligibility value is not within the preset optical signal conversion optimization range obtained from the database, an alarm prompt is sent; the optical signal conversion optimization eligibility value is represented by the absolute value corresponding to the difference between the optical signal conversion accuracy quantitative value of the optical signal conversion optimization final state of the fiber transceiver and the optical signal conversion accuracy quantitative value of the optical signal conversion optimization initial state of the fiber transceiver; the optical signal conversion optimization eligibility value is used to reflect the eligibility degree of the optical signal conversion optimization.

[0052] It should be added that after the optical signal conversion accuracy is evaluated as qualified, the optical fiber transmission accuracy is evaluated, and whether to perform optical fiber transmission compensation is determined based on the optical fiber transmission accuracy evaluation result. The specific process is as follows: the total attenuation value of the optical fiber line is obtained; the total power loss of the optical signal from the transmitting end of the optical fiber transceiver to the receiving end of the optical fiber transceiver in the preset optical fiber transmission time period is used as the total attenuation value of the optical fiber line through the optical power meter; the total attenuation value of the optical fiber line is used to reflect the accuracy of the optical signal during optical fiber transmission; if the obtained total attenuation value of the optical fiber line is not greater than the preset optical fiber line attenuation value, a prompt indicating that the optical signal monitoring of the optical fiber transceiver is qualified is sent, and the prompt is fed back to the preset Internet of Things monitoring center, where the preset optical fiber line attenuation value is represented by the average value of the total attenuation value of the optical fiber line in the historical time period; if the obtained total attenuation value of the optical fiber line is greater than the preset optical fiber line attenuation value, a prompt indicating that the optical signal monitoring of the optical fiber transceiver is unqualified is sent, and optical fiber transmission compensation is performed; performing optical fiber transmission compensation indicates sending a prompt to the preset personnel based on the wavelength division multiplexing method, namely WDM (Wavelength Division Multiplexing). Wavelength division multiplexing (WDM) reduces interference between optical signals of different wavelengths to improve the accuracy of optical fiber transmission. If the total attenuation value of the optical fiber line obtained after optical fiber transmission compensation is still greater than the preset optical fiber line attenuation value, an alarm prompt will be sent. Otherwise, a notification indicating that the optical signal monitoring of the optical fiber transceiver is qualified will be sent and fed back to the preset IoT monitoring center.

[0053] In this embodiment, by controlling the optical signal conversion optimization qualified value within the preset optical signal conversion optimization range, the accuracy and stability of the optical fiber transceiver in converting the optical signal can be ensured, and data errors caused by inaccurate conversion can be reduced; by monitoring the total attenuation value of the optical fiber line, it is helpful to promptly discover attenuation problems in the optical fiber link and reduce communication interruptions caused by link failures; when a prompt for optical fiber transmission compensation is received, optical signals of different wavelengths are transmitted separately through the wavelength division multiplexing method to reduce mutual interference between them, which helps to improve the accuracy and efficiency of optical fiber transmission; thereby achieving an improvement in the accuracy of the monitoring results of the optical signal conversion performed by the optical fiber transceiver.

[0055] Depend on Figure 5 It can be seen that when the number of discharges monitored at the preset time point exceeds the threshold line, the status prompt at the preset time point is abnormal and requires preset personnel to handle it. That is, when the normal status prompt is received (current transmission is stable), the optical signal conversion monitoring interface can be entered.

[0056] Depend on Figure 6 It can be seen that when an abnormal conversion state is monitored, the redundant channels can be automatically switched and redundant verification can be performed through the electrical interface scheduling; the preset personnel can adjust the redundant verification from low to high by adjusting the adjustment intensity; when there is no abnormality in the redundant verification, the interface still displays the normal alarm indicator light.
