Therefore, the invention provides the optical cable quality detection method and the optical cable quality detection system, the optical cable is automatically selected through the first instruction for quality detection, a large amount of manpower and material resources are saved, and the detection cost of the online optical time domain reflectometer is reduced; the first curve is generated and displayed by combining the detection result of the handheld optical time domain reflectometer, so that the detection result is more accurate and visual, and the stability and reliability of the optical cable quality detection are improved; through the loss position of location optical cable and demonstration, promoted optical cable quality testing's efficiency.
Hereinafter, a method and a system for detecting quality of an optical cable according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings, and first, a method for detecting quality of an optical cable according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, an optical cable quality detection method is provided in an embodiment of the present invention, and the optical cable quality detection method in the embodiment of the present invention may be applied to a terminal, a server, software running in the terminal or the server, or the like. The terminal may be, but is not limited to, a tablet computer, a notebook computer, a desktop computer, and the like. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware service, a domain name service, a security service, a Content Delivery Network (CDN), a big data and artificial intelligence platform, and the like.
Referring to fig. 2, the overall system interface architecture of the embodiment of the present invention includes a sensing layer, an acquisition layer, and an application layer, where the sensing layer includes a handheld optical time domain reflectometer for temporary testing and an online optical time domain reflectometer for 24 hours real-time online. Therefore, two approaches are taken to collect OTDR data. And after the acquisition layer completes data analysis and acquisition, transmitting all OTDR original data from different sources to a database of an upper application system server through a network for the upper application system to perform graphical analysis and presentation.
The optical cable quality detection method in the embodiment of the invention mainly comprises the following steps:
s101, generating a first instruction;
the first instruction comprises optical cable selection information, and the optical cable selection information is used for selecting a first optical cable as an optical cable to be detected.
S102, detecting the first optical cable through a first optical time domain reflectometer according to the first instruction to generate a first detection result;
the first optical time domain reflectometer is an online optical time domain reflectometer. The basic working principle of OTDR is: the detection pulse light is injected into an optical fiber channel to be detected by the aid of the bidirectional coupler, backward Rayleigh scattering light generated when the detection pulse light is transmitted forwards in an optical fiber medium is coupled into the photoelectric detection circuit by the aid of the bidirectional coupler, and the quality of the optical fiber bearing service is analyzed and judged through a signal returned by the photoelectric detection circuit. According to the existing OTDR, the optical fiber generates a Rayleigh scattering curve along the optical fiber after being subjected to OTDR detection, the loss condition along the optical fiber core passage is visually represented through the Rayleigh scattering curve, and the abnormal conditions of the fusion point, the joint, the crack, even the breakpoint and the like of the optical fiber are reflected, so that whether the optical fiber has the defects of fracture, poor joint coupling and medium nonuniformity is judged.
Specifically, since the core components (such as light source and sensor) of the OTDR are expensive, and the number of fiber cores of the optical cable to be detected is large, if each optical cable is equipped with an OTDR, the cost will be greatly increased. In the embodiment of the present invention, an optical switch is added to the OTDR, and when performing the optical cable quality detection, the first instruction is generated in step S101, and the fiber core of the optical cable to be detected is switched by the optical switch according to the first instruction, so that the OTDR and the optical cable 1 to be detected are implemented: n detection requirements and effects.
S102 may be further divided into the following steps S1021-S1023:
step S1021, according to the first instruction, connection between the first optical time domain reflector and the first optical cable is established;
specifically, according to a first instruction, the optical switch is controlled so that the first optical time domain reflectometer establishes connection with the optical cable to be detected (i.e. the first optical cable).
Step S1022, generating a second instruction;
wherein the second instruction comprises a detection parameter.
Specifically, detection parameters including a test range, a test pulse width, a measurement time, a group refractive index, an ending threshold and a non-reflection threshold are configured in the real-time online equipment acquisition server, and a second instruction is generated.
And step S1023, detecting the first optical cable according to the detection parameters according to the second instruction, and generating the first detection result.
Specifically, in the embodiment of the present invention, a communication connection between the real-time online device acquisition server and the first optical time domain reflectometer is established through Socket, and the second instruction generated in step S1022 is sent to the first optical time domain reflectometer, so that the first optical time domain reflectometer performs quality detection on the first optical cable according to the detection parameters, and returns the first detection result to the real-time online device acquisition server.
S103, obtaining and analyzing an SOR data file to generate a second detection result;
the SOR data file is optical cable quality original data of the first optical cable detected by a second optical time domain reflectometer, and the second optical time domain reflectometer is a handheld optical time domain reflectometer.
Specifically, the handheld optical time domain reflectometer does not have a network communication capability, and further cannot provide a standardized secondary development interface. Therefore, in the embodiment of the present invention, the detection result of the handheld optical time domain reflectometer is exported to an SOR data file, and the data in the SOR data file is parsed by the SOR parsing server to generate a second detection result, and the second detection result is sent to the handheld terminal acquisition server of the acquisition layer.
S103 may be further divided into the following steps S1031-S1033:
Step S1031, obtaining the SOR data file;
specifically, in the embodiment of the present invention, the second optical time domain reflectometer automatically generates an SOR data file after performing quality detection on the first optical cable and exports the SOR data file through the USB port, and obtains the SOR data file through the SOR parsing server.
S1032, compressing the SOR data file by adopting a Douglas-rarefaction algorithm to generate a second curve;
it can be understood that, because the SOR data file stores the original data of the optical cable quality detected by the second optical time domain reflectometer, the data amount is huge. In order to reduce the pressure of data analysis and improve the efficiency of data analysis and presentation, in the embodiment of the invention, the SOR data file is compressed by adopting a Douglas-rarefaction algorithm to generate a second curve.
Specifically, an original OTDR curve is generated from the SOR data file, and the original OTDR curve is approximately represented as a series of points by the douglas-rarefaction algorithm, and the number of points is gradually reduced. The method comprises the following steps:
(1) connecting the head point and the tail point of the original OTDR curve to form a straight line AB;
(2) searching a point C with the maximum distance from the straight line AB in the original OTDR curve, and calculating to obtain a distance D between the point C and the straight line AB;
(3) Presetting a threshold value T, when D is more than or equal to 2T, dividing the curve into two segments of AC and BC by using a C point, and respectively operating the two segments of AC and BC according to the steps (1) to (3);
(4) and when the D is less than 2T, connecting the obtained straight lines to be used as an approximate curve of the original OTDR curve, namely the second curve.
And step S1033, analyzing the second curve to generate a second detection result.
Specifically, after the SOR data file is compressed into a second curve through a Douglas-rarefaction algorithm, the second curve is analyzed through an SOR analysis server to generate a second detection result, and the second detection result is sent to a handheld terminal acquisition server.
S104, generating and displaying a first curve according to the first detection result and the second detection result;
referring to fig. 3, a vertical axis of the first curve is an attenuation value of optical power, and a horizontal axis of the first curve is a cable detection distance.
Specifically, the acquisition layer sends the first detection result and the second detection result to a server of the application layer, and the server performs graphical analysis and presentation by combining the first detection result and the second detection result to generate and display a first curve. It will be appreciated that in one embodiment of the invention, when the first optical cable is detected by the first optical time domain reflectometer only, the server receives only the first detection result and performs graphical analysis and presentation based on the first detection result to generate and display a first curve; and when the first optical cable is detected only by the second optical time domain reflectometer, the server only receives the second detection result, performs graphical analysis and presentation according to the second detection result, and generates and displays a first curve.
And S105, acquiring and displaying the loss position of the first optical cable according to the distance information of the mutation point in the first curve.
The catastrophe point is a point where the attenuation value on the first curve suddenly decreases, and the distance information is a value of an abscissa of the catastrophe point.
Specifically, as can be seen from step S104, the vertical axis of the first curve represents the attenuation value of the optical power, and the horizontal axis represents the cable detection distance. When the first curve has a sudden drop in the longitudinal direction, the point A at the sudden drop is a mutation point, and the abscissa K corresponding to the mutation point0The distance, i.e. the distance information, is detected for the optical cable. Detecting the optical cable with the mutation pointThe distance measurement is combined with an electronic map imported by a GIS platform, the position of the loss position of the first optical cable corresponding to the mutation point on the electronic map is obtained and displayed
