Newer designs ntawm sij hawm - ncua relays siv hluav taws xob circuits nrog resistor-capacitor ( RC ) networks los tsim ib ncua sij hawm , ces energize ib txwm (instantaneous) electromechanical relay coil nrog lub tshuab hluav taws xob cov circuit tso zis.
Nyob rau hauv txoj kev no, dab tsi yog lub sij hawm ncua relay siv rau?
Lub sij hawm ncua relays tsuas yog tswj relays nrog a ncua sij hawm Lawv lub hom phiaj yog tswj ib qho kev tshwm sim raws li sij hawm.
Tom qab, lo lus nug yog, yuav ua li cas lub xeev lub sij hawm ncua relay ua hauj lwm? Cov keyboards no tig ntawm lub load thaum tswj voltage yog thov thiab qhov voltage hla qhov zero point ntawm AC sine yoj, ua rau me ntsis ncua ntawm qhov tig- ntawm ntawm khov kho - lub xeev timer . Raws li nrog lwm tus relays , cov relay tig tawm thaum tswj voltage yog tshem tawm.
Ntawm no, dab tsi yog lub sij hawm relay?
A Timer Relay yog kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob electromechanical relay thiab tswj Circuit Court. Lub sij hawm ncua relays yog pib los yog tshwm sim los ntawm ib qho ntawm ob txoj hauv kev: Daim ntawv thov ntawm cov khoom siv hluav taws xob / cov khoom siv pabcuam yuav pib lub tsev lossis ua kom nws npaj pib thaum lub teeb liab tshwm sim.
Yuav ua li cas koj sim lub sij hawm ncua relay?
Burden Test
- Kho lub timer nrog lub sij hawm qeeb qeeb piv txwv li: 2 feeb.
- Siv lub zog relay nrog 125V thiab ntsuas qhov dc tam sim no.
- Nco tseg tam sim no ua ntej timer ua haujlwm.
- Tom qab 2 feeb relay yuav tuaj tos. Nco ntsoov qhov tam sim no tom qab ua haujlwm.
- Xam cov relay fais fab (W) = 125v x ntsuas tam sim no.

Qhov txawv ntawm lub sij hawm lapse thiab lub sij hawm lapse yog dab tsi?
Ib qho hyperlapse, ntawm qhov tod tes, tsis muaj kev txwv li no: 'Nws ua rau lub koob yees duab txav mus rau ntau qhov deb,' Tompkinson hais. Hauv lwm lo lus, hyperlapse zoo ib yam li lub sijhawm ua haujlwm, tab sis nrog ntau qhov kev sib tw
Dab tsi yog ncua sij hawm hauv AngularJS?
Deferred Object: Deferred yog ib yam khoom uas nthuav tawm cov lus cog tseg. Nws muaj peb txoj hauv kev daws(), tsis lees paub(), thiab ceeb toom(). Deferred rov cog lus khoom. Thaum Deferred tiav, Koj hu rau txoj kev daws teeb meem (), tsis lees paub (), thiab ceeb toom ()
Dab tsi yog qhov ncua sij hawm ntau lub hauv paus tsim?
Hauv ntau lub hauv paus tsim, cov ntaub ntawv hauv paus ib txhij tau sau los ntawm ob lossis ntau tus cwj pwm. Hauv kev tsim qauv ncua sij hawm, kev sau cov ntaub ntawv hauv paus rau kev coj tus cwj pwm tom ntej yog pib tom qab lub hauv paus rau kev coj cwj pwm ua ntej
Lub sij hawm ntawv puas muaj lub sij hawm?
Lub ntsiab txhais ntawm UNIX timestamp yog timezone ywj siab. Lub sij hawm yog tus naj npawb ntawm vib nas this (lossis milliseconds) tau dhau los txij li qhov taw qhia meej hauv lub sijhawm, ib tag hmo ntawm Lub Ib Hlis 1 1970 hauv UTC lub sijhawm. Txawm hais tias koj lub sijhawm nyob ntawm lub sijhawm, lub sijhawm teev sawv cev rau lub sijhawm uas zoo ib yam nyob txhua qhov chaw
Koj txhais li cas compile lub sij hawm tas li hauv Java Dab tsi yog siv compile lub sij hawm tas li?
Compile-time constants thiab variables. Cov ntaub ntawv Java hais tias: Yog hais tias ib hom thawj zaug los yog ib txoj hlua txhais tau tias yog qhov tas li thiab tus nqi raug paub thaum lub sij hawm sau, lub compiler hloov lub npe tas li txhua qhov chaw hauv cov cai nrog nws tus nqi. Qhov no yog hu ua compile-time constant
