For convenience of understanding, a specific flow of an embodiment of the present invention is described below, and referring to fig. 1, an embodiment of an optical cable identification method in an embodiment of the present invention includes:
101. acquiring knocking waveform data according to the detection channel, wherein the knocking waveform data is data generated by knocking an optical cable facility point;
it is understood that the executing subject of the present invention may be an identification device of an optical cable, and may also be a terminal, which is not limited herein. The embodiment of the present invention is described by taking a terminal as an execution subject.
The optical cable facility points comprise optical cable wells, electric poles, communication sign piles and the like. The optical cable check out test set of this embodiment adopts the optical cable to patrol the line analysis appearance, and the optical cable patrols the check out passage and the target optical cable of line analysis appearance and is connected, and the optical cable patrols the line analysis appearance and has 20 check out passages, and every check out passage corresponds connects an optical cable, for example, the optical cable patrols No. 5 check out passage connection target optical cables of line analysis appearance, and the terminal acquires according to No. 5 check out passage and strikes waveform data.
In one example, the optical cable line patrol analyzer can acquire an initial waveform of a target operation optical cable under a vibration-free condition in real time and send the initial waveform to a terminal; and the maintainer can check the initial waveform corresponding to the target operation optical cable through the terminal. Or, the optical cable inspection analyzer acquires that the target operation optical cable has a waveform with a preset vibration amplitude and a vibration position corresponding to the target operation optical cable through the server under the vibration condition, and sends the waveform with the preset vibration amplitude and the vibration position to the terminal, the maintainer can check the waveform with the preset vibration amplitude and the vibration position corresponding to the target operation optical cable through the terminal, for example, the maintainer knocks a plurality of optical cable well covers to be detected, so that the optical cable in the optical cable well to be detected by the target generates vibration, and then the identification device of the optical cable judges whether the initial waveform corresponding to the target operation optical cable is converted into the waveform with the preset vibration amplitude.
102. When the knocking waveform data meet a first vibration waveform condition, confirming that a target optical cable connected with a detection channel exists at an optical cable facility point, and acquiring distance data of the target optical cable at the optical cable facility point according to the knocking waveform data;
the first vibration waveform condition is used for representing that the amplitude value of the knocking waveform corresponding to the knocking waveform data is larger than or equal to a first preset amplitude value, and the distance data is used for representing the length of the target optical cable from the machine room to the optical cable facility point.
For example, based on the example of step 101, if the initial waveform corresponding to the target operation optical cable is converted into a waveform with a preset vibration amplitude, that is, the waveform vibration change exists in the target optical cable well to be detected in the knocked optical cable well, the optical cable identification device determines that the target operation optical cable exists in the optical cable well, determines the target optical cable well to be detected as the target optical cable well, and can generate downhole information to instruct a maintainer to downhole, and check information such as the number of optical cables in the target optical cable well; further, the maintainer can also record the number of the optical cables in the optical cable well into the terminal.
103. Acquiring frequency domain waveform data of the detection channel under the distance data, wherein the frequency domain waveform data is generated by loading vibration on candidate optical cables in the optical cable facility points by vibration equipment at a preset frequency;
vibrating devices include vibrating pens and other devices that can produce a fixed frequency of vibration. For example, at least two candidate cables exist in the cable well, and the candidate cables in the cable facility point are vibrated by a maintenance person by using a vibrating pen with the frequency of 800HZ, so that the terminal acquires frequency domain waveform data of the detection channel under the distance data. Specifically, if the corresponding optical cable is connected with the optical cable line patrol analyzer, and a vibration pen is used for loading vibration at the distance length a of the optical cable, the optical cable line patrol analyzer returns a group of frequency domain data with a vibration value at the position point of the distance data corresponding to the distance length a, and if the position is not aligned or not corresponding to the channel, the returned frequency domain data value is very small and has no oscillation.
Illustratively, the number of cables in the cable well is 2, respectively: the optical cable identification device comprises a first candidate optical cable and a second candidate optical cable, and if the first position of the first candidate optical cable has waveform vibration change, the first candidate optical cable is determined as a target operation optical cable by the optical cable identification device.
104. And when the frequency domain waveform data meets the second vibration waveform condition at the preset frequency, determining the candidate optical cable as the target optical cable.

For example, when the frequency domain waveform amplitude value corresponding to the frequency domain waveform data at the preset frequency is greater than or equal to the second preset amplitude value, the terminal determines that the candidate optical cable is the target optical cable.
In the embodiment of the invention, the optical cable facility point through which the target optical cable passes is determined by acquiring the knocking waveform data of the optical cable facility point, the frequency domain waveform data of the candidate optical cable in the optical cable facility point is further acquired, and the target optical cable is finally determined, so that the manual workload is reduced, the damage rate of the optical cable is reduced, and the efficiency of identifying the target optical cable from a large number of optical cables is improved.
In one embodiment, after the step of identifying the candidate cable as the target cable, the method further comprises the steps of:
and generating and issuing corresponding reminding information based on the target optical cable.
The reminding information can be sound reminding information or character reminding information, for example, the optical cable identification device generates corresponding reminding information based on the target optical cable, the reminding information is sound reminding information, and the reminding information is sent to the playing module; the playing module plays the prompt tone of the ticker, the ticker and the ticker; or the reminding information is character reminding information, and the terminal displays a character popup prompt of the target optical cable.
Referring to fig. 2, another embodiment of the method for identifying an optical cable according to the embodiment of the present invention includes:
201. acquiring knocking waveform data according to the detection channel, wherein the knocking waveform data is data generated by knocking optical cable facility points;
the optical cable patrols line analysis appearance can acquire the initial waveform of target optical cable under the condition of no vibrations in real time, and with initial waveform transmission to terminal, the initial waveform that the maintainer can look over the target optical cable through the terminal and correspond, perhaps the optical cable patrols line analysis appearance and acquires the target optical cable and strikes waveform data under the condition of vibrations, will strike waveform data transmission to terminal, the maintainer can look over the waveform data that strikes that the target optical cable corresponds through the terminal, for example, the maintainer strikes optical cable facility point, lead to the optical cable in the optical cable facility point to produce vibrations, thereby patrol line analysis appearance through the optical cable and gather corresponding waveform data that strikes, and then the terminal acquires strikes waveform data.
202. When the knocking waveform data meet a first vibration waveform condition, confirming that a target optical cable connected with a detection channel exists at an optical cable facility point, and acquiring distance data of the target optical cable at the optical cable facility point according to the knocking waveform data;
the first vibration waveform condition is used for representing that the amplitude value of the knocking waveform corresponding to the knocking waveform data is larger than or equal to a first preset amplitude value, and the distance data is used for representing the length of the target optical cable from the machine room to the optical cable facility point. For example, the first preset amplitude value may be 30000, the first preset amplitude value may be set according to an actual application scenario, when the amplitude value of the knocking waveform corresponding to the knocking waveform data is greater than or equal to 30000, the terminal determines that the target optical cable connected to the detection channel exists at the optical cable facility point, and obtains distance data of the target optical cable at the optical cable facility point according to the knocking waveform data, where the distance data is 800 meters.
203. Acquiring frequency domain waveform data of the detection channel under the distance data, wherein the frequency domain waveform data is generated by loading vibration on candidate optical cables in the optical cable facility points by vibration equipment at a preset frequency;
specifically, (1) the terminal acquires a position point corresponding to the distance data; (2) the terminal collects point frequency domain data of the position points; (3) And the terminal generates frequency domain waveform data according to the point frequency domain data.
For example, based on the example of step 202, the terminal acquires a position point corresponding to 800 meters, the terminal collects point frequency domain data of the position point, and the terminal generates frequency domain waveform data according to the point frequency domain data.
204. Unpacking the frequency domain waveform data according to a protocol of equipment communication to obtain unpacked data;
the unpacked data is binary stream data, for example, taking a candidate optical cable a as an example, the terminal unpacks the frequency domain waveform data of the candidate optical cable a according to the protocol of the device communication to obtain the binary stream data of the candidate optical cable a.
205. Converting and splicing the unpacked data to generate a corresponding coordinate array of an object numbered musical notation format with a non-fixed length and a certain frequency interval;
since the binary stream data cannot intuitively display specific physical information about the candidate optical cable, the binary stream data needs to be converted into a coordinate array in an Object numbered Notation format with a non-fixed length and a certain frequency interval by a preset code conversion tool, in this embodiment, a JS Object numbered Notation (JSON) is adopted as the Object numbered Notation format, and the JSON is a lightweight data exchange format.
206. Constructing a coordinate system on a graph page of a graph library based on the frequency, the y-axis parameter and the x-axis parameter, and sending a coordinate array on the graph page of the graph library at regular time to generate a frequency domain waveform corresponding to the frequency domain waveform data, wherein the frequency domain waveform comprises a frequency domain waveform amplitude value;
specifically, a coordinate system is constructed based on frequency and other relevant parameters, the generated coordinate arrays are substituted and connected, and one or more signal wave diagrams are generated, wherein the signal wave diagrams include but are not limited to length information based on the signal wave diagrams. And marking the acquired coordinate array on an MPCort graphic page in a timer mode, and observing that a waveform changes at a speed of every second on a graphic interface. The x-axis coordinate corresponding to the highest point on the y-axis is the length of the optical cable.
Exemplarily, the identification device of the optical cable unpacks the frequency domain data of the optical cable a according to the protocol of the device communication to obtain unpacked data corresponding to the optical cable a; the identification device of the optical cable carries out conversion splicing on unpacked data corresponding to an optical cable A to be detected to generate a coordinate array of an object numbered musical notation format, wherein the coordinate array is not fixed in length and has a certain frequency interval, and the coordinate array corresponds to the optical cable A; the optical cable identification device constructs a coordinate system on a graph page of a graph library based on frequency, y-axis parameters and x-axis parameters, and sends a non-fixed-length coordinate array with a certain frequency interval in an object numbered notation format corresponding to the optical cable A to the graph page of the graph library at regular time to generate a frequency domain waveform corresponding to the optical cable A.
207. And when the frequency domain waveform data meets the second vibration waveform condition at the preset frequency, determining the candidate optical cable as the target optical cable.
The second vibration waveform condition is used for indicating that the frequency domain waveform amplitude value corresponding to the frequency domain waveform data is larger than or equal to a second preset amplitude value. For example, the second preset amplitude value may be 40000, which may be set according to an actual application scenario, and when the frequency domain waveform amplitude value corresponding to the frequency domain waveform data is greater than or equal to 40000, the terminal determines that the candidate optical cable is the target optical cable.
Optionally, in a possible implementation manner, (1) if the frequency domain waveform data does not satisfy the second vibration waveform condition at the preset frequency, the terminal acquires frequency domain waveform data corresponding to the detection channel at the candidate position point, where the candidate position point is a position point within a preset range with the reference position point as a center; (2) If the frequency domain waveform data corresponding to the alternative position point meets a second vibration waveform condition, the terminal confirms that the alternative optical cable is the target optical cable; (3) And if the frequency domain waveform data corresponding to the alternative position point does not meet the second vibration waveform condition, the terminal acquires the frequency domain waveform data corresponding to other candidate optical cables in the optical cable facility point at the reference position point and the alternative position point, and judges whether the frequency domain waveform data meet the second vibration waveform condition or not until the target optical cable is identified.
For example, if the reference location point is 500 meters, the candidate location point may be 505 meters or 495 meters, if the frequency domain waveform data does not satisfy the second vibration waveform condition at the preset frequency, the terminal acquires the frequency domain waveform data corresponding to the detection channel at 505 meters or 495 meters, if the frequency domain waveform data corresponding to 505 meters or 495 meters satisfies the second vibration waveform condition, the terminal confirms that the candidate optical cable is the target optical cable, and if the frequency domain waveform data corresponding to 505 meters or 495 meters does not satisfy the second vibration waveform condition, the terminal acquires the frequency domain waveform data corresponding to the reference location point and the candidate location point of other candidate optical cables in the optical cable facility point, and determines whether the second vibration waveform condition is satisfied until the target optical cable is identified.
For another example, if the reference position and the candidate position in the first target candidate optical cable do not have waveform vibration change, the optical cable identification device performs waveform vibration detection on the second target candidate optical cable, that is, the optical cable identification device determines whether the reference position corresponding to the second target candidate optical cable has waveform vibration change, and the reference position corresponds to the length of the second target optical cable from the machine room to the optical cable facility point; and if the waveform vibration change exists at the reference position corresponding to the second target candidate optical cable, the optical cable identification device determines the second target candidate optical cable as the target operation optical cable. And if the reference position corresponding to the second target candidate optical cable does not have the waveform vibration change, the optical cable identification device judges whether the candidate position in the second target candidate optical cable has the waveform vibration change or not, and if any position of the candidate positions in the second target candidate optical cable has the waveform vibration change, the optical cable identification device determines the second target candidate optical cable as the target optical cable.
In one embodiment, before the step of acquiring the tapping waveform data according to the detection channel, the method further includes:
acquiring a test instruction; the test instruction comprises a detection channel and optical signal pulse width information;
and sending the pulse width information of the optical signal to optical cable detection equipment.
Specifically, the optical cable detection equipment is detection equipment with multiple detection ports; each detection port corresponds to the detection channel one by one, and each detection port is used for being connected with each target optical cable one by one. The terminal can obtain a test instruction comprising a detection channel and optical signal pulse width information and send the optical signal pulse width information to the optical cable detection equipment; the optical signal pulse width information is used for indicating the optical cable detection equipment to transmit corresponding pulse optical signals to the target optical cable. Based on this, the embodiment of the application can configure the test parameters of the optical cable detection equipment through the terminal, switch the detection channel and improve the efficiency of optical cable identification.
In the embodiment of the invention, the optical cable facility point where the target optical cable passes is determined by obtaining the knocking waveform data of the optical cable facility point, the frequency domain waveform data of the candidate optical cables in the optical cable facility point is further obtained, and the target optical cable is finally determined, so that the manual workload is reduced, the damage rate of the optical cable is reduced, and the efficiency of identifying the target optical cable from a large number of optical cables is improved.
In one embodiment, the target cable needs to be found in a cable well with multiple cables, and the specific steps are as follows:
step 1:
earlier stage work: an optical cable is connected to an optical cable line patrol analyzer in a machine room, the analyzer is provided with 20 detection channels, and an optical cable is connected to each channel. The optical cable inspection analyzer is equipment which can continuously upload vibration data and frequency domain data of one frame to a mobile terminal according to different positions in an optical cable through different optical cables.
And 2, step:
after the optical cable line patrol analyzer is connected, the optical cable line patrol analyzer can continuously and actively return binary stream data; after the terminal takes the binary stream data, unpacking the binary stream data according to a protocol of communication with equipment to obtain one frame of data of a frequency domain waveform, then combining the binary stream data to obtain frequency domain data of a fixed json format, then marking the obtained frequency domain data on an MP Chart graphic page in a timer mode in 125 milliseconds, and then seeing a waveform with vibration change on a graphic interface.
And step 3:
when the mobile terminal is used, vibration analysis data in the mobile terminal application is used to confirm which detection channels (optical cables) pass through the well, and approximate distance data from each cable of the cables passing through the well to the well is known and recorded.
And 4, step 4:
after the confirmation, the cover is opened, the well is lowered, then the mobile terminal is used for opening the frequency domain waveform data, the vibration pen with the adjusted 800HZ frequency is used for touching the optical cables one by one, and the target optical cables in communication connection with the detection channels corresponding to the optical cable routing analyzer in the optical cables are searched.
And 5:
