AChithunzi cha LEDIzi zikugwiritsidwa ntchito mwadzidzidzi zimawoneka zowoneka bwino chifukwa cha zovuta zosonyeza. Ngati idatayika pamwambo wotsegulira kwambiri, zingakhale zosasinthika. Momwe Mungatsimikizirekudalirika komanso kukhazikika kwa chizindikiroKutumiza kwakhala mutu womwe mainjiniya amayenera kukumana nawo. Chizindikiro chimafota pamene mtunda ukuwonjezeka nthawi yofalitsa. Kusankha kwa sing'anga yotumiza ndikofunikira kwambiri.
01 siginecha
Sikovuta kumvetsetsa kuti zizindikilo, ngakhale pakati pa sing'anga zimadalira kufalikira, tidzazindikira munthawi yofalitsa. Titha kuwona chithokomiro cha RS-485 monga dera lofanana ndi magawo angapo omwe akuletsa, indector. Kutsutsa kwa waya sikuthandiza kwenikweni pa siginecha ndipo amatha kunyalanyazidwa. Mphamvu yogawika C ya chingwe imapangidwa makamaka ndi mawaya awiri ofanana awiri opotoka. Kutayika kwa zizindikiro kumachitika makamaka chifukwa cha zosefera za LC yodutsa zopangidwa ndi zovuta zomwe zimagawidwa ndikuwongolera chingwe. Mulingo wapamwamba kulumikizana, chachikulu kwambiri. Chifukwa chake, kuchuluka kwa kuchuluka kwa deta sikuli kwakukulu kwambiri ndipo njira yofalitsira siyokwezeka kwambiri, timasankha ma baud 9600 BPS.
02 Kuganizira Kwambiri Pazigawo Zoyankhulirana
Kuphatikiza pazizindikiro, chinthu china chomwe chimakhudza kufalikira kwa chizindikiro ndikuwunika. Kumpirirani kuluka ndi kum'konda chifukwa ndi zifukwa ziwiri zazikulu zowonetsera mabasi. 1, kusokoneza, makamaka kumatanthauza kuvuta kwa chip pakati pa 485 chip ndi mzere wolumikizirana. Cholinga chotsimikiza ndichakuti mzere wolumikizirana ndi wopanda pake, chizindikiro chonse cholumikizirana ndi changu. Kamodzi mtundu uwu wa chiwonetsero chazizindikiro zomwe munthu amafanana ndi 485 Chip, chizindikiro cholakwika chidzachitika. Yathu yothetsera vutoli ndikusintha bus kuti iwonjezere kubisala ndi mtengo wina wotsutsana ndi mzere wina, wolekanitsidwa ndikukoka, kotero zizindikiro zosatsimikizika komanso zosokoneza sizimachitika. 2, kunyengerera kukana chimodzimodzi ndi chiwonetsero chomwe chachitika chifukwa cha kuwala komwe kumayambitsa sing'anga wina. Ngati chizindikiro cha chinsinsi cholumikizira chingwe chotsika kwambiri kapena ngakhale chosagonjetsedwa kumapeto kwa mzere woundadwa, zimayambitsa izi. Njira yogwiritsidwa ntchito kwambiri yothetsera mawonekedwe awa ndikuti alumikizane ndi chinsinsi kumapeto kwa chingwe chomwe chimafanana ndi chingwe chofanana ndi chinsinsi cha chingwe, ndikupangitsa chinsinsi kupitilizabe. Chifukwa cha kufalikira kwa zingwe pazithunzi, kutsutsana komwe kumafunikira kulumikizidwa kumapeto kwina kwa chingwe cholumikizirana.
03 Mphamvu ya Kugawidwa kwa Mphamvu Yogawidwa pa Kutumiza Mabasi
Chingwe chofalitsira nthawi zambiri chimakhala cha zingwe zopindika, ndipo capercaciation chimachitika pakati pa mawaya awiri omwe ali ndi zingwe zopotoka. Palinso njira ina yaying'ono yofananayo pakati pa chikho ndi dziko lapansi. Chifukwa chakuti chizindikiro chofala pabasi chimapangidwa ndi "1" ndi "0" ndikumana ndi mitundu yapadera monga 0x01, mulingo wogawika kuti aperekedwe mkati mwa nthawi inayake. Komabe, pamene mulingo "1" Kuyimbidwa Mwangozi wa Cakocator sikungatulutsidwe munthawi yochepa, zomwe zimapangitsa kuti zizindikiridwe zikuluzikulu komanso zomwe zimakhudza kuchuluka kwa deta yonse.
04 khalani ndi promita yofananira komanso yodalirika
Mtunda wolumikizirana ndi wafupikitsa ndipo malo ogwiritsira ntchito sakhala ndi vuto lalikulu, nthawi zina timangofunika kulumikizana pang'ono kuti mutsirize ntchitoyi, koma malo ambiri ogwira ntchito sakhala chonchi. Kuyambira koyambirira kwa ntchitoyi, zinthu monga luso ndi luso (monga kusunga mizere inayake pakati pa mizere yolumikizirana, ndipo ngakhale mutakhala ndi maaya osokoneza bongo omwe amagwirizanitsa kulumikizirana kwa dongosololi. Chifukwa chake, ndikofunikira kwambiri kukulitsa njira yolumikizirana yokwanira.
