Tej kub detection yog tsim nyog nyob rau hauv industrial ntau lawm thiab txhua hnub lub neej. Feem ntau siv txoj kev los ntes tej kub yog siv ib qho optical kub sensor tso rau hauv ib puag ncig los ntsuas cov ambient kub ntawm qhov chaw ntawd. Xyoo tsis ntev los no, Kev tshawb fawb rau fiber Bragg gratings kuj qhia sophisticated thiab ib lub npe kub hauv daim teb ntawm fiber optics. With the deepening of research, the manufacturing process of fiber Bragg gratings and the photosensitivity of fibers have gradually improved, and fiber Bragg gratings have been widely used in various modern fields. Compared with other sensing devices, the advantages of low cost and high stability of fiber Bragg grating sensing devices make them widely used. Tib lub sijhawm, due to the fact that the grating itself is engraved in the fiber core, it is easy to connect with the fiber system and integrate the system, which makes fiber Bragg grating sensors convenient for application in various long-distance distributed detection systems.
Cov Yam Ntxwv ntawm cov yam ntxwv Fiber Bragg Grating Sensor

It has become one of the fastest developing technologies in the sensing field and has been widely used in civil engineering, aerospace, petrochemical, hwj huam, kev kho mob, shipbuilding and other fields.
Fiber Bragg Grating Cable Temperature Measurement System
During the operation of cables, the wires will generate heat. Under the influence of factors such as excessive load, local defects, and external environment, the heating of cable wires will increase compared to normal conditions. Under long-term ultra-high temperature operation, the insulation material will quickly age and become brittle, and the insulation will be broken down, leading to short circuits and even fires, causing serious accidents. Usually, Nws tsis yooj yim los ntes tej defects hauv lub cable pw txoj kev thaum mus soj ntsuam, thiab feem ntau tsuas yog tom qab ib malfunction los sis txawm muaj kev huam yuaj tshwm sim, ua teeb meem loj losses, Uas remedial ntsuas noj.

Electrochemical zog cia yog tam sim no qhov tej-ntug zog cia tshuab, Cov uas lithium-ion roj teeb kuj yog cov pheej zog cia tshuab vim lawv muaj zog density, Hwj huam density thiab zog conversion tus nqi, thiab luj. Lithium roj teeb pob yog ib qho tseem ceeb tivthaiv uas twb muaj lawm loj-teev zog cia tshuab, Nws yog composed ntawm ib tug xov tooj ntawm lithium roj teeb hlwb txuas nrog koob thiab parallel. Thaum lub lag luam ntawm lithium roj teeb, a large amount of heat accumulates due to internal chemical and electrochemical reactions, causing high temperatures and shortening their service life and posing safety issues. In addition, the temperature differences and imbalances between individual lithium battery cells can affect the lifespan of the entire lithium battery pack. Thaum tam sim no, thermistor or thermocouple methods are commonly used for temperature monitoring of energy storage lithium battery packs. To monitor each individual lithium battery cell in the lithium battery pack, a large number of devices are required, wiring is complex, and the measurement signal is susceptible to electromagnetic interference. Yog li ntawd, vim, the above two methods are not suitable for temperature monitoring of large-scale energy storage lithium battery packs.
Fiber Bragg Grating kub ntsuas tswvyim rau cov hwjchim lawv
Optical circuit Board yog lub ntsiab tivthaiv onboard electronic khoom, thiab cov kev kawm ntawm lub Circuit Board ncaj qha mus rau qhov zoo onboard electronic khoom. Tam sim noadays, Raws li microelectronics tshuab nkag mus rau lub era ntawm ultra loj teev integrated circuits, Lub circuits nyob rau hauv cov tub rog aircraft yog qhov qhia txoj. Daim ntawv thov ntau daim ntawv thov kev pab ntau txheej txheem printed boards, mount, thiab loj-teev integrated circuits tau ua txhaum kev mob ntawm circuit Boards qhia nyuaj. Raws li Joule txoj cai, Tam sim no kis los ntawm ib circuit Court thaum lub lag luam yuav ua kom muaj kev kub ntxhov dissipation. Yog muab piv rau qhov kub ntawm cov components, Qhov chaw ntawm lub faulty tivthaiv yuav txiav txim tau. People have begun to try to determine the working status of each component by detecting the temperature distribution and temperature changes during the operation of the circuit board, in order to locate faults on the circuit board. The most common method for diagnosing circuit board faults based on component heating currently is to use infrared thermal imagers to locate faults in the circuit board. tiam sis, the temperature resolution and accuracy of infrared thermal imagers are not high, and they can only roughly measure the temperature of a large area. Yog li ntawd, vim, they cannot detect the temperature of some components with small temperature changes, nor can they accurately detect the temperature of some small components. In addition, the method of fault analysis through voltage detection of key points is only suitable for analyzing circuits with known schematics or circuits with simple structures. When analyzing faults in large-scale integrated circuit boards and circuit boards with unknown schematics, the efficiency is not high and it does not have replicability.
Principle of Fiber Bragg Grating Temperature Sensor
A sensor that detects temperature by detecting the shift in the center wavelength of the light signal reflected by an internal sensitive component – a fiber optic grating. Installation structures with different types of packaging such as surface, embedded, and immersion. Due to the fact that fiber optic grating temperature sensors use light waves to transmit information, and optical fibers are electrically insulated and corrosion-resistant transmission media, they are not afraid of strong electromagnetic interference. This makes them convenient and effective for monitoring in various large-scale electromechanical, petrochemical, metallurgical high-pressure, strong electromagnetic interference, qhov khuv, explosive, and highly corrosive environments, with high reliability and stability. In addition, the measurement results of fiber optic grating temperature sensors have good repeatability, which makes it easy to form various forms of fiber optic sensing networks and can be used for absolute measurement of external parameters. Multiple gratings can also be written into one optical fiber to form a sensing array, achieving quasi distributed measurement.
Features of Grating Sensor Products:
Passive, uncharged, inherently safe, not affected by electromagnetic interference and lightning damage; Multi point serial multiplexing, high temperature measurement accuracy and resolution without being affected by light source fluctuations and transmission line losses, can directly transmit signals remotely through optical fibers (over 50km)
