Lub hauv paus tswj hwm kev tswj hwm txhua lub qhov rooj tsheb. Lub kaw lus muaj lub qhov rooj kaw xauv, hloov ua haujlwm thiab txuas xov hlau. Thaum kuaj mob thiab kho, feem ntau yog txwv tsis pub kuaj txhua qhov hluav taws xob thiab tsav tsheb, txheeb xyuas qhov ua yuam kev thiab tshem tawm lawv.
Cov Lus Qhia
Kauj ruam 1
Lub hauvpaus haujlwm nruab nrab siv ob-txoj kev solenoids los ntsuas thiab qhib lub qhov rooj. Cov kev hloov pauv tau muaj ob txoj haujlwm: "kaw" (kaw) thiab "qhib" (qhib). Cov hloov hluav taws xob ua kom muaj qhov txuas ntxiv uas xa cov voltage mus rau lub qhov rooj kaw solenoids. Ua raws li cov teeb liab raug xa mus, cov hloov pauv hloov nws qhov polarity mus rau qhov zoo lossis tsis zoo rau ob qhov ntawm Circuit Court.

Thaum kho lub hauv nruab nrab txhav tas, ua ntej ntawm txhua qhov kuaj xyuas qhov kev tiv thaiv ntawm lub qhov hluav taws xob. Ntxiv nrog rau kev txaws, cov ntsuas hluav taws xob tuaj yeem siv rau hauv lub tsheb. Txav mus rau cov hloov ntawm ib txoj haujlwm mus rau lwm qhov ntau zaus. Lub cav yuav tsum tawm. Mloog: koj yuav tsum hnov qhov tsaus muag nyem los ntawm kev sib tos.

Yog tias tsis muaj cov nias, kos rau voltage ntawm lub keyboards. Yog tias hluav taws xob muaj tam sim no, kuaj lub xov tooj hluav taws xob nyob nruab nrab ntawm lub thawv fuse thiab cov ntsuas hluav taws xob lawv tus kheej. Yog tias koj pom qhov qhib qhib lossis luv luv hauv Circuit Court, tshem tawm lawv. Yog tias qhov teeb meem txuas ntxiv, kuaj lub pob hloov rau lub peev xwm nqa khoom tam sim no. Yog tias cov hloov hluav taws xob tsis ua hluav taws xob hauv ib qho chaw twg, hloov lawv nrog cov tshiab.
Kauj ruam 4
Yog tias tus hloov hluav taws xob ua haujlwm, tab sis qhov nyem ntawm qhov txuas tawm tsis tau hnov, xyuas cov hluav taws xob txuas nruab nrab ntawm cov keyboards thiab tus xa mus. Yog tias pom kev tawg, kho lub kav hlau. Kos rau relay. Yog tias cov relay tau txais qhov hluav taws xob los ntawm qhov hloov tab sis tsis xa nws mus rau solenoids, tshawb xyuas qhov xwm txheej ntawm cov teeb meem xa tawm. Yog tias qhov av tau yog qhov tseeb, hloov lub xa mus.
Kauj ruam 5
Yog tias qhov hluav taws xob solenoid ntawm ib qho ntawm lub qhov rooj tsis ua haujlwm, tshem tawm cov sab hauv ntawm lub qhov rooj sib nug xov thiab kuaj pom qhov cuam tshuam ntawm voltage ntawm solenoid nyob rau ob qho chaw hloov. Hauv qhov no, qhov voltage yuav tsum nyob ntawm ib lub xov tooj thaum lub hloov nyob rau hauv "kaw" txoj haujlwm. Thaum koj hloov txoj haujlwm ntawm qhov hloov, voltage rau ntawm cov xov no yuav tsum ploj, nyob rau lwm yam - nws yuav tsum tshwm sim. Yog tias tsis yog, hloov cov solenoid. Nrog rau kev ua tiav ntawm qhov tsis muaj ntawm voltage ntawm solenoid, tshawb xyuas cov xwm txheej ntawm cov xov hlau los ntawm solenoid mus rau txuas ntxiv.
