The multifunctional optical cable testing and positioning instrument has three core functions: fault tracking, cable census, and OTDR modes provide comprehensive and efficient solutions for cable maintenance and management.
First, the fault tracking function may enable limited distance fault location up to 50 km. An operator holds the device to the optical fiber distribution frame, then knocks the device near the fault point, and the fault point is quickly positioned through the function display of the reflected power and the distance. The technology provides an accurate and convenient means for fault location and powerfully supports the operation of in-station staff and patrol staff during optical cable rush repair.
Specifically, the fault location of the multifunctional optical cable testing and positioning instrument further comprises: the multifunctional optical cable test positioning instrument is used for measuring vibration and measuring loss, and comprises the steps of positioning a vibration part based on a vibration measurement result, and obtaining the distance between a fault point and a site based on the loss measurement result so as to obtain a fault positioning result.
The function of the multifunctional optical cable test locator comprises a vibration measuring function, and specifically comprises the following steps:
the method comprises the steps of transmitting test laser to an experimental optical cable through a laser, carrying out physical deformation interference on the optical cable in the transmission process, detecting reflected optical signals through an optical oscilloscope, and calculating the phase difference phi of two optical signal waveforms after deformation and no deformation, wherein the specific calculation formula is as follows:
Φ＝(ω1-ω2)t+(Φ0l-Φ02)
wherein ω1 and ω2 are the angular frequency of the deformation-free optical signal and the angular frequency of the deformed optical signal, Φ0l and Φ02 are the angular frequency of the deformation-free optical signal and the initial phase of the angular frequency of the deformed optical signal, respectively, and t is time, so as to obtain the variation value of the phase difference Φ along with time.
The multifunctional optical cable testing and positioning instrument comprises a loss measuring function, and specifically comprises:
the experimental optical cable is deformed, the phase difference value is recorded in real time by utilizing the principle of extending the phase by Raman amplification, and the phase difference value is drawn into a change curve; meanwhile, the principle of reflected light time testing of an optical time domain reflectometer is utilized, the time point reflected by the anti-phase change point is compared with the light speed, the optical length between the phase point and the light-emitting point is obtained, the distance between the phase point and the light-emitting point is calculated according to the optical length, the phase point is a fault point, the light-emitting point is a station, and the distance is the distance between the fault point and the station.
The pressure of the external deformation received by the optical cable at the point can be obtained by combining the phase difference curve obtained by measuring vibration, and the optical distance measurement can be realized under the condition of not damaging the line by utilizing the principle.
Further, the optical cable census function of the multifunctional optical cable test locator can cover a length of 50 km. By adopting a simple method for bending the optical cable, the optical cable can be identified, and the bending diameter of the optical cable can reach 1m. Compared with the traditional optical cable identification method, the optical cable general investigation function has a brand-new detection technology without damaging the optical cable, can obviously reduce the optical cable rush repair maintenance time, reduce engineering construction and management cost and improve the working efficiency. The function requires cooperation of two engineering technicians, one is an instrument operator responsible for testing and the other is an optical cable operator responsible for bending the optical cable, and the two are matched, so that the optical cable is identified through indication of the instrument and trace diagram display.
Under the OTDR mode of the multifunctional optical cable test locator, the transmission time and the transmission distance can be converted according to the following formula:
d＝c×t
2IOR
where c is the speed of light, t is the time it takes for the echo signal to reach the OTDR, IOR is the refractive index of the fiber, and d is the distance of the device emitting the light pulse to the point of failure.
Transition of the positioning mode of the fault point of the optical cable: the traditional positioning of the fault point of the optical cable has more defects, when the optical cable fails, the optical cable needs to be tested at one end of the optical cable by using an OTDR, but the data obtained by the OTDR test is only the optical distance of the fault point, and the long-time test of the optical cable line cannot be realized due to the problem of the service life of the OTDR, so that the positioning of the fault point of the optical cable needs to be repeatedly tested, which is time-consuming and laborious and violates the basic requirement of smart grid construction. After the project is developed, another solution is provided for locating the fault point of the optical cable. When the optical cable faults occur, the monitoring equipment developed in the project is utilized to realize continuous testing of the optical cable at the optical cable terminal, the rush repair personnel knocks the optical cable at the position adjacent to the fault point, the approach to the fault point is realized through the equipment to the reflected waveform change curve, the knocking does not need to cut the optical cable, any damage is not caused to the optical cable, and the gradual positioning of the fault point can be realized. And for the buried optical cable in the urban pipe gallery, the ground cover is not required to be opened, so that the working difficulty and working time of the optical cable rush repair are greatly reduced, and the construction of the intelligent power grid is promoted.
The measuring mode of the multifunctional optical cable testing and positioning instrument can not damage the optical cable in the measuring process, and meanwhile, the multi-point position test can be realized; the operation is simple, the equipment can continuously run in fixed time, and the stepping point is more convenient. A proper operation model can be provided for a plurality of application ranges such as the investigation of the built optical cable or the positioning of fault points. Compared with the traditional OTDR which needs 3-4 times of measurement, the device can obtain an accurate result by only one time of measurement, and the time is reduced by 10% -20% compared with the traditional method.
As shown in fig. 2, the use flow of the multifunctional optical cable testing and positioning instrument specifically includes the following steps:
step 1, an maintainer carries a multifunctional optical cable testing and positioning instrument to reach an optical cable distribution frame in a station of a testing station, and selects one function of fault positioning, optical cable census and OTDR according to requirements;
step 2, the field staff uses the Beidou handheld terminal to reach the position of the connector box and report coordinate information;
step 2, the staff swings the optical cable reciprocally, and the in-station maintainer obtains the optical distance from the multifunctional optical cable test positioning instrument;
step 3, uploading the optical distance to a database of an optical cable resource intelligent management platform;
and 4, analyzing the data by the optical cable resource intelligent management platform, converting the data into useful line operation and maintenance and line rush repair data, and finishing updating the database, wherein in the process, the system guarantee function guarantee system can normally and safely run.
