Example 1
Referring to fig. 1-2, a first aspect of the present invention provides an optical fiber ribbon cable with a self-warning function, which includes an optical fiber ribbon 1 and a sheath 2 disposed around the optical fiber ribbon 1.
Further, the sheath 2 is of a cylindrical hollow structure, the hollow part of the sheath is a containing cavity 21 for containing the optical fiber ribbon, and the optical fiber ribbon 1 is arranged in the containing cavity 21, so that foreign matters can be effectively prevented from entering the optical cable, and meanwhile, the mechanical collision can be prevented from damaging the inner structure of the optical cable, so that a good protection effect is achieved. In a possible embodiment, the sheath 2 may be made of polyethylene, which has excellent low temperature resistance, while having good chemical stability and resistance to attack by most acids and bases.
Further, a plurality of groups of detection lines 3 are further provided in the sheath 2 along the length direction thereof, wherein the plurality of groups of detection lines 3 are disposed around the optical fiber ribbon 1, and the detection lines 3 are used for detecting the state of the optical fiber ribbon cable, and the detection manner will be further described below.
In a possible implementation manner, the state of the optical fiber ribbon cable can be detected by adopting a phase OTDR technology, it is understood that the optical fiber generates tiny strain under the action of environmental vibration or sound field, the refractive index of the optical fiber changes correspondingly due to the photoelastic effect, so that the interference phase of the rayleigh scattering optical signal in the optical fiber changes, and each point on the optical fiber is regarded as a sensor unit, and distributed detection of vibration or acoustic wave signals in the surrounding environment of the detection optical fiber is realized by utilizing phase demodulation and signal processing. When a damage event (such as construction near a pipeline, artificial damage or theft, natural disasters and the like) possibly related to the optical cable or the pipeline occurs, micro vibration generated by the behavior of the damage event deforms the optical fiber in the optical cable, and the vibration signal is captured, so that real-time monitoring of the optical cable and accurate positioning of an accident place are realized.
Specifically, phase OTDR techniques typically include the steps of: the laser emits laser to enter the field optical cable through the light path part; when the optical cable is subjected to external vibration, part of laser with field vibration information returns along the optical cable; the laser entering the light path part enters a photoelectric detector to be converted into an electric signal; and carrying out data acquisition and analysis on the electric signals to generate an alarm, and displaying the alarm on an electronic map. Wherein, the positioning principle is as follows: the speed v of the laser in the optical fiber, the time t from the laser to the return, can calculate the position L=v×t/2; further, the recognition principle is as follows: the returned laser has on-site vibration signals, and the measured parameters are deduced after the information such as the intensity, the frequency, the phase change and the like of the signals is analyzed and then the demodulated data is analyzed and processed, so that the external changes needing to be perceived are approximately restored.

Further, the buffer tank 4 is filled with the solution, and after the buffer tank 4 is filled with the solution, the influence of external low-frequency vibration on the buffer tank 3 can be effectively reduced by arranging the detection line 3 between the buffer tank 4 and the accommodating cavity 21, so that the difficulty of subsequent noise reduction treatment is reduced, and the quality of OTDR detection data is further ensured. In addition, through after filling solution in buffer tank 4, if sheath 2 appears damaging, then the solution in buffer tank 4 will outwards flow under the pressure effect to lead to the pressure in buffer tank 4 to descend, change appears in the low frequency vibration separation effect to the outside, simultaneously, outwards spun rivers send high frequency sound, can carry out high frequency vibration location detection to detection line 3 through phase OTDR and discern the accurate position of specific damage, realize quick determination and the accurate location of damage.
Further, the optical fiber ribbon 1 is disposed in the loose tube 11, and the optical fiber ribbon 1 is distributed in the accommodating cavity 21 in an annular array, and a buffer core 5 is further disposed in the center of the optical fiber ribbon 1 distributed in the annular array along the length direction of the optical cable, wherein the buffer core 5 is disposed in the geometric center of the optical cable, air is filled in the buffer core, and the buffer core is used as a central reinforcing structure of the whole optical cable to play a role in structural elastic support, and when the whole optical cable is subjected to external pressure, the hardness of the buffer core 5 is lower than that of the loose tube 11, so that the buffer core 5 can be subjected to flattened form change, and the stress of the external pressure to the inside is eliminated, so that the extrusion fracture of the loose tube 11 is prevented, and the effect of regulating and controlling the action between the loose tubes 11 is played.
In a preferred embodiment, the inner wall of the sheath 2 is further provided with a plastic-coated aluminum tape 6, so that the interference of the external optical fiber ribbon cable can be effectively reduced.
In a more preferred embodiment, the filling rope 7 is disposed in the accommodating cavity 21, the filling rope 7 is disposed in the gaps between the loose tubes 11, when the optical fiber ribbon cable is bent, the filling rope 7 will be bent synchronously, the inner side of the bending part of the filling rope 7 is pressed and the outer side is pulled in the bending process, so that the bending force of the optical fiber ribbon cable is resisted by the pulling force, the whole stress effect of the optical fiber ribbon cable in bending can be greatly reduced, on one hand, the tensile resistance of the optical fiber ribbon cable is improved, and on the other hand, the bending supporting force of the optical fiber ribbon cable can be also remarkably improved.
Further, a system processing center is included, wherein the system processing center is connected to the detection line 3, and the system processing is used for starting the phase OTDR to detect the state of the optical fiber ribbon cable.
It can be understood that the phase OTDR is opened through the system processing center to detect the state of the optical fiber ribbon cable, so that the influence on data transmission caused in the process of monitoring the vibration optical fiber by the OTDR can be reduced, thereby realizing the trigger type accurate self-detection and positioning of long-time standby, avoiding the influence on data transmission caused by frequent self-detection in the traditional mode and realizing the self-early warning process of the optical fiber ribbon cable.

101. acquiring a first pressure value in a buffer tank;
102. and starting phase OTDR detection based on the first pressure value.
It will be appreciated that when the ribbon cable is in a normal state, the pressure in the buffer tank 4 is usually kept within a certain range, and if external factors such as breakage or excessive pressure bearing change, the pressure value of the solution in the buffer tank 4 will also change synchronously.
Further, the enabling phase OTDR detection based on the first pressure value comprises:
103. if the first pressure value is smaller than the first pressure preset value, starting phase OTDR detection;
104. if the first pressure value is larger than the second pressure preset value, starting phase OTDR detection;
wherein the first pressure preset value is smaller than the second pressure preset value;
it can be understood that when the buffer tank 4 is damaged, the solution in the buffer tank 4 will flow out under the action of pressure, which will result in the reduction of the pressure value in the buffer tank 4, and when the pressure value is smaller than the first pressure preset value, the open phase OTDR detection is used for quickly determining and accurately positioning the damaged portion of the optical fiber ribbon cable. On the other hand, because of construction and the like, the optical fiber ribbon cable bears too much pressure, and when the pressure value is larger than the second pressure preset value, the phase OTDR is started, and the construction vibration is utilized to accurately position the construction site.
Further, the self-early warning method of the optical fiber ribbon cable with the self-early warning function further comprises the following steps:
201. acquiring a second pressure value in the buffer core;
202. starting phase OTDR detection based on the second pressure value;

203. if the second pressure value is smaller than the third pressure preset value, starting phase OTDR detection;
204. if the second pressure value is larger than the fourth pressure preset value, starting phase OTDR detection;
wherein the third pressure preset value is less than the fourth pressure preset value;
it can be understood that the optical fiber ribbon cable is excessively loaded due to construction and the like, and when the pressure value in the buffer core is greater than the second pressure preset value, the phase OTDR is started for detection.
Further, the system processing center can effectively improve the accuracy of the optical fiber ribbon cable in the self-early warning process by acquiring the pressure values in the buffer tank 4 and the buffer core 5 to start the phase OTDR detection, compared with the method of only acquiring the pressure values in the buffer tank 4 to start the phase OTDR detection or only acquiring the pressure values in the buffer core 5 to start the phase OTDR detection.
It should be noted that, in particular, the buffer core 5 is disposed in the geometric center of the optical fiber ribbon cable, and when the second pressure value is smaller than the third pressure preset value, it may be that the buffer core 5 leaks, or it may be that the inside of the optical fiber ribbon cable is damaged. It will be appreciated that if the interior of the ribbon cable is broken, communication will be interrupted.
Further, the self-early warning method of the optical fiber ribbon cable with the self-early warning function further comprises the following steps:
301. judging the state of the optical fiber ribbon cable according to the first pressure value and the second pressure value;
the judging of the state of the optical fiber ribbon cable comprises the following steps:
302. if the first pressure value is smaller than the first pressure preset value and the communication is normal, the sheath of the optical fiber ribbon cable is damaged;
303. if the second pressure value is smaller than the third pressure preset value and the communication is normal, the buffer core is damaged.
Finally, it should be noted that: the embodiment of the invention is disclosed only as a preferred embodiment of the invention, and is only used for illustrating the technical scheme of the invention, but not limiting the technical scheme; although the invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art will understand that; the technical scheme recorded in the various embodiments can be modified or part of technical features in the technical scheme can be replaced equivalently; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
