Mfumo wa Ufuatiliaji wa Alarm ya Fiber Optic ya Vibration, Utangulizi, Mwongozo Kamili, Juu 10 Watengenezaji wa 2025-INNO

Mtetemo daima imekuwa mada muhimu ya utafiti katika uwanja wa sayansi na teknolojia. Vihisi vya mtetemo hutumiwa kwa kawaida katika nyanja mbalimbali kama vile utambuzi wa mawimbi ya tetemeko, haidrofoni za fiber optic, mtihani usio na uharibifu, utafutaji wa mafuta na gesi, udhibiti wa mchakato wa viwanda, na ufuatiliaji wa afya ya kimuundo. Sensorer za jadi za mtetemo ni pamoja na vihisi vya capacitive au piezoelectric, ambazo zina unyeti mkubwa lakini hazifai kwa voltage ya juu, sehemu za uga wa juu wa sumaku kama vile vituo vidogo. Sensorer za vibration za Fiber optic zina anuwai ya matumizi katika uendeshaji wa kituo cha mfumo wa nguvu na ufuatiliaji wa usalama kwa sababu ya insulation yao ya asili., kinga ya kuingiliwa kwa umeme na magnetic, ukubwa mdogo, uzito mwepesi, na uwezo mkubwa wa kuzidisha. Daima zimekuwa mada motomoto ya utafiti na matumizi ndani na nje ya nchi.

Fiber optic vibration sensors detect changes in optical parameters such as light intensity, masafa, urefu wa mawimbi, awamu, and polarization state in optical fibers by sensing external vibrations. The purpose of detecting external parameters is achieved by detecting changes in optical parameters in optical fibers. In optics, a Fabry Perot interferometer is a multi beam interferometer composed of two parallel glass plates, where the inner surfaces of the two glass plates facing each other have high reflectivity. In fiber optic vibration sensors, the Fabry Perot interferometer has a unique attraction because it can provide a non-contact and disturbance free vibration analysis device, and has also been proven to have significant performance advantages in vibration and displacement measurement.

Vibration measurement has a wide range of applications in many fields. These fields include the detection of sound and ultrasonic signals, earthquake monitoring, oil exploration, vibration modal analysis of various mechanical systems, and water listening systems. Kwa sasa, existing vibration sensors can be divided into electromagnetic vibration sensors, variable capacitance vibration sensors, and piezoelectric vibration sensors according to their different principles.

These vibration sensors are all electrical sensors. There is another type of vibration sensor that corresponds to electrical sensors, namely fiber optic vibration sensors. Ikilinganishwa na sensorer za umeme, fiber optic vibration sensors have significant advantages such as anti electromagnetic interference, upinzani wa kutu, maisha marefu ya huduma, ukubwa mdogo, na uwezo wa kufikia kipimo cha usambazaji wa pointi nyingi kwa njia ya kuzidisha kwa urefu wa wimbi la macho. Kwa hiyo, wana jukumu kubwa katika hali ambapo sensorer za jadi za umeme haziwezi kutumika (kama vile kuwaka na kulipuka). Aidha, sensorer za vibration za fiber optic pia zina faida ya unyeti wa juu, kwa hivyo zina jukumu muhimu katika programu nyingi zinazohitaji ugunduzi wa ishara dhaifu za mtetemo. Vihisi vya juu vya unyeti wa mtetemo wa nyuzi macho mara nyingi hutumia teknolojia ya mwingiliano wa fiber optic, na mifumo ya kuhisi ya nyuzi za interferometric huathirika na mabadiliko ya nje ya mazingira, kama vile mabadiliko ya halijoto ambayo mara nyingi husababisha kuyumba katika mifumo ya kuhisi ya nyuzi za macho ya interferometric. Njia kuu ya kutatua tatizo hili ni kupitisha aina fulani ya teknolojia ya fidia.

Aina ya S kengele inayotetemeka ya mzunguko wa nyuzi macho ni bidhaa ya hivi punde zaidi iliyotengenezwa na FJINO kulingana na mfumo wa kengele wa mzunguko wa fibre optic uliojiendeleza., kebo moja inayotetemeka mfumo wa kengele wa mzunguko wa nyuzi macho, na mfumo wa kengele wa mzunguko wa nyuzinyuzi za vibrating unaotegemea mtandao, ambayo inakamilisha uwezo wa kila mmoja na kutumia kikamilifu faida za bidhaa. Msururu huu wa bidhaa unaangazia kuboresha vipengele mbalimbali muhimu kama vile algoriti za kengele na mbinu za mawasiliano, kutoa suluhisho nyingi ili kukidhi mahitaji tofauti ya watumiaji na maeneo tofauti. Upinzani bora wa upepo na mvua.
