Maitiro ekuyera sei tembiricha yevashanduri muchitima chekufambisa uye zvakanakira zvefiber optic tembiricha zvinodzora

Fiber optic tembiricha sensor, Intelligent monitoring system, Yakaparadzirwa fiber optic mugadziri muChina

Why does the traction power supply system of rail transit need to use fluorescent fiber optic temperature measurement
The power supply systems for traction power supply in urban rail transit in China are DC750V and DC1500V, corresponding to the current collection methods of the third rail and overhead contact network, respectively. The maximum voltage of the secondary winding of this power supply system’s transformer has exceeded 1000V, but the measurement range specified in the “Electronic Temperature Controller for Transformers” (JB/T7631-2016), which uses Pt100 as the temperature sensor, can only be limited to below 1000V. Naizvozvo, njanji yekufambisa ine yakakwira voltage kuramba zvinodiwa kune tembiricha sensor probes uye inotungamira.

Iyo fiber optic tembiricha controller yechitima chekufambisa inoshandisa fluorescent fiber optic tembiricha sensors sezvinhu zvinonzwa tembiricha.. Iyi tembiricha inonzwa chinhu haina kudzivirirwa kune electromagnetic kukanganiswa uye inoshingirira kune yakakwira voltage (100KV/fiber kusvika pasi inotungamira kureba kwe0.4m). Fluorescent fiber optic kuyerwa kwetembiricha inocheka zvachose kukanganiswa kwezvinhu zvekuyera tembiricha zvinoendeswa kune tembiricha controller kubva kune yekuyera tembiricha sosi., kuvandudza mwero wekuchengetedza njanji.

Zvakanakira zveFluorescent Fiber Optic Temperature Measurement System Inoshandiswa muRail Transit.
Kunzvimbo yekushanda yenjanji transit transformers, kuparadzaniswa uye kudzivirira kubva kunze kwemagetsi kupindira zviratidzo zvinowanikwa kubva kune magetsi, kuguma kwekuisa chiratidzo, chiratidzo chinobuda kupera, uye tembiricha yekudzora bhokisi shell.

Iyo magetsi emagetsi sisitimu yenjanji yekufambisa traction magetsi yakavakirwa paDC750V uye DC1500V., nepo kuyerwa kwechiyero kunotsanangurwa mu “Electronic Temperature Controller for Transformers” (JB/T7631-2005), which uses Pt100 as the temperature sensor, can only be limited to below 1000V. Naizvozvo, iyo fiber optic tembiricha controller ine yakanyanya kusimba voltage kuramba uye inogona kumira 100KV.

Mukupindura kuvibration, huruva, mwando, kusvibiswa kwemafuta uye dzimwe nzvimbo dzekushanda panzvimbo, akawanda-layer ekudzivirira matanho anotorwa kuve nechokwadi chekuti optical fiber tembiricha yekudzora njanji ine yakanaka electromagnetic inoenderana., kuve nechokwadi chekushanda kwakagadzikana uye kwakavimbika kwemutongi wekushisa.

Dhizaini misimboti yefluorescence fiber optic tembiricha yekuyera system
Nheyo yekushandisa
Kuvakwa kwehurongwa kunonamatira kune musimboti wekuita. Pahwaro hwekuita, kufambira mberi uye kufanoona zvinotariswa, uye mwero, zvigadzirwa zvepamberi uye zvakakura uye mapuratifomu ekusimudzira anosarudzwa kuvaka sisitimu inoshanda uye inogadzirisa matambudziko anoshanda.
Standardization musimboti
Iyo system software uye hardware mapuratifomu uye maturusi ekuvandudza mashandisirwo anoshandiswa mukuvaka kwekushandisa anofanirwa kuenderana nemitemo yenyika, zviyero zveMinistry of Information Industry, yakakodzera tekinoroji yakatarwa uye zvinodiwa nekambani.
Nheyo yekufanana
Kutevedzera mutemo wepakati pekutonga ruzivo, kuronga kwese, dhizaini yose, uye nhanho-ne-nhanho kuita, hurongwa hwekuita hunosanganisira nheyo ina dzakabatana: hutungamiri hwakabatana, kuronga kwakabatana, mipimo yakabatana, uye sangano rakabatana uye kushandiswa.
Kuvimbika musimboti
Iyo software uye hardware zviwanikwa zvinoda kuve nechokwadi kusakanganiswa uye kwakavimbika kushanda kweiyo fiber optic tembiricha yekuyera system ye 7 × 24 maawa. Naizvozvo, zvinodikanwa kushongedza dhizaini yakakwana yematanho ekuvimbika kuti ive nechokwadi chekushanda kwakavimbika kwehurongwa uye kunyatsofunga nezve kuvimbika zvinodiwa zvekiyi system application..
Yakavimbika kuchengetedza nzira
Iyi sisitimu inotora akatevedzana akachengeteka encryption matanho, ine yakavakirwa-mukati 64 bit encryption algorithm. Iyo sisitimu ine kuchengetedzwa kwepamusoro uye inogona kudzivirira zvinobudirira kudonha kwedata uye kuba, kuve nechokwadi chekuchengetedzwa, kururama, uye kutendeseka kweiyo data data, uye kudzivirira mashandiro evatyairi zvisiri pamutemo uye mashandiro emushandisi ari pamutemo.
Iyo yekushandisa interface iri nyore, ushamwari, uye vakangwara zvikuru
Iyo sisitimu inotarisa otomatiki huchokwadi hweiyo data yekuisa uye inopa hushamwari kukurumidza kune zvikanganiso zvemushandisi.
Kushanda kwakagadzikana uye data yakavimbika.
Chikuva chiri nyore kushanda, nyore kugona, uye nzira yekuisa iri nyore. Data inogona kugadzirwa otomatiki mune akasiyana mishumo sezvinodiwa, kuvandudza kugona kwehutungamiriri.

Nhanganyaya kune wiring uye kuisirwa kwefiber optic tembiricha zvinodzora zvenjanji
Structural framework
Iyo system ine zvikamu zvitatu: fluorescent fiber optic tembiricha controller, fluorescent fiber optic probe, uye fiber optic yekukurukurirana software.

 

Iyo data yekufambisa pakati peiyo backend system uye tembiricha yekuyera terminal inotora RS485 nzira yekutaurirana.

Yese data kuunganidzwa, management, uye tembiricha kuratidza inopedzwa nekukurukurirana software, uye iyo sisitimu inonyanya kuona kuunganidzwa kwedata uye kutarisisa kuyerwa kwekushisa. Iyo fiber optic tembiricha yekuyera terminal inosanganisa akawanda-channel fluorescent optical fibers, kupa ekunze RS485 kutaurirana, anti-kupindira, uye dhizaini isingadziviriri.

Mashandisirwo emabasa eiyo optical fiber tembiricha yekuyera system mune njanji yekufambisa
Real time monitoring
Iyo data yekuunganidza density inogona kuiswa zvinoenderana nezvinodiwa nevatengi, uye iyo sisitimu ichaunganidza data nguva nenguva zvichibva pane yakatarwa paramita. Zvadaro, icharatidzwa mune tafura fomu kana curve kudhirowa kuwana chaiyo-nguva yekutarisa. Nguva chaiyo yekutarisa mamiriro ekushandisa kwemidziyo; Nguva chaiyo yekutarisa uye kurekodha kweiyo reactor tembiricha.
