By automatic monitoring on an optical cable line of the optical cable monitor, an optical cable line hidden trouble can be early discovered; obstacle duration is effectively compressed; maintenance of an optical cable network is changed from passivity to activity; real time monitoring on an optical cable is realized; a fault position is accurately displayed on a screen; maintenance time and workload are effectively compressed; quality and deteriorated characteristic of long-term operation of the optical cable are analyzed; and a fault hidden trouble is effectively prevented. The optical cable monitor can be widely applied to optical cable laying, daily maintenance, field construction and fault analysis; is an optical cable monitor of plug and play through a USB jack; and is small, economical, convenient and of high efficiency.
Description
Technical field
The utility model relates to a kind of dynamic monitoring device, specifically is a kind of monitoring instrument of optical cable running status of saying so, and the main monitoring that realizes the whole network optical cable and circuit is for relevant department provides the operation of the whole network lightguide cable link accurately, the multidate information of maintenance state.
Background technology
Fiber cable network is one of modern main communication network, along with the increase of communication network capacity, and the continuous expansion of optical cable scale, the transmission structure of network also becomes increasingly complex.Communications optical cable is carried out in real time, monitors automatically; In time find potential faults; When breaking down, fast light path is switched to alternate channel, let network manager know in time and what problem where, when to have occurred; And the potential faults solution of proposition fiber optic network, crucial realistic meaning is arranged.But this technology still belongs to blank at present, and it is extremely urgent therefore to develop a suitable monitoring instrument.
Summary of the invention
Goal of the invention: the purpose of the utility model is to overcome the deficiency of prior art, and a kind of fiber optic cable monitor appearance is provided, and builds perfect, fast monitoring cable network system, solves the problem that can't understand the optical cable running status in the prior art in time, effectively.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of fiber optic cable monitor appearance, it comprises power supply, power supply is connected with the data acquisition process center through power supply control chip; Power supply also is connected with the optical time domain reflectometer module; The optical time domain reflectometer module is connected with data acquisition process center, USB interface respectively; The data acquisition process center also is connected with input unit, display unit, memory respectively.
What wherein, described power supply adopted is polymer Li-ion battery.
Wherein, described data acquisition process center is the INTEL Atom chip that intel corporation is produced.
Beneficial effect: the utility model is to the automatic monitoring of lightguide cable link; Can find lightguide cable link hidden danger early, effectively compress obstacle and last, the maintenance of fiber cable network is from a passive one to an active one, realize real-time monitoring to optical cable; Accurately in the screen display abort situation; Can compress preventive maintenance time, workload effectively, analyze quality, the degradation characteristic of optical cable long-time running, effectively trouble saving hidden danger.Can be widely used in optical cable laying, regular maintenance, field construction and accident analysis, be a through USB jack plug and play fiber optic cable monitor appearance, small and exquisite, economical, convenient, efficient.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model
Embodiment:
As shown in the figure, the fiber optic cable monitor appearance of the utility model comprises power supply 1, and power supply 1 is connected with data acquisition process center 3 through power supply control chip 2; Power supply 1 also is connected with optical time domain reflectometer module 4 (OTDR module) respectively; Optical time domain reflectometer module 4 is connected with data acquisition process center 3, USB interface 8; Data acquisition process center 3 also is connected with input unit 5, display unit 6, memory 7 respectively.
Wherein, what described power supply 1 adopted is polymer Li-ion battery, is data acquisition process center 3,4 power supplies of optical time domain reflectometer module.The Intel Atom chip that described data acquisition process center 3 produces for intel corporation; Realize the management and the control of whole system; Be connected with optical time domain reflectometer module 4 through serial ports 0, realize the reception and the control of optical cable information, thereby obtain the relevant information of communication line real-time condition; Be connected with memory 7 through serial ports 1, realize information stores.Input unit 5 is in order to start, shutdown and open self check button, parameter setting; Display unit 6 is for showing the LCD display of detection information curve chart etc.
During use, the USB interface 8 of the utility model is connected on the connector of optical cable, after the energising, the utility model can be started working.After the light pulse that optical time domain reflectometer module 4 is sent is injected into optical cable, receive two kinds of information from optical cable: a kind of is the Fresnel reflection light of optical cable section or linkage interface; Another kind is a Rayleigh scattering light.Optical time domain reflectometer module 4 passes to data acquisition process center 3 with these information, through the power of these rear orientation lights of Measurement and analysis, can obtain the attenuation curve that distributes along cable length.Through analyzing attenuation curve, can know the attenuation degree of optical cable then to light signal, the position of the tie-point in the optical cable, Coupling point and breakpoint, and optical cable is crooked and the excessive situation of pressurized also can measure easily.Finish rear indicator 6 of the information of detecting shows test curves automatically, and stores into automatically in the memory 7.
The utility model has solved centralized maintenance system machine room lower unattended operation and has needed the on-the-spot contradiction that cooperates test of personnel; Controlling a plurality of OTDR modules through network remote easily detects optical cable automatically; Keep simultaneously the mobility and the flexibility of instrument field work again, improved attendant's the labor productivity and the maintenance quality of network greatly.Fiber optic cable monitor, alarm, accident analysis, location, fault management, line upkeep, line management, operation flow and safeguard system are for the safe and highly efficient operation of fiber cable network provides safeguard.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
