The kachipangizo moyandikana pa foni - ndichiyani? mafoni

Chifukwa cha mankhwala amakono zamagetsi zida ndi zipangizo zotha kuti azindikire njira za chinthu, mwachitsanzo, chala, ndi kiyibodi kapena khutu la munthu kuti foni. Njira imeneyi chimagwiritsidwa ntchito kukhudza mapanelo amitundumitundu, amene kumatha kusinthitsa zipangizo makina ndi moyo wautali utumiki wawo. Ndipo ambiri akhoza anafunsa: a moyandikana sensa pa foni - ndichiyani ndipo kodi ntchito? chipangizo ichi tikambirana hereinafter mawu kukhazikitsa pa luso capacitive.

njira kuzindikira

Kuvomerezeka chiyerekezo cha luso contactless Mwachangu anapeza ntchito m'munda wa zipangizo kunyamula zoyendetsedwa paokha. Chithunzichi chimagwiritsidwa ntchito zitsanzo atsopano a mafoni ndi pamagome, osewera nyimbo. cholinga chake chachikulu ndi kuonjezera kudalirika kwa zipangizo ndi kupulumutsa mphamvu zamagetsi.

Unit anasonyeza adzakhala deactivated bola ngati njira ndi wapezeka dzanja wosuta, ndi udindo ndi kachipangizo moyandikana pa foni yanu. Ndi chiyani icho - adzakhala bwino ngati tikambirana mfundo za ntchito zake. Pankhani ntchito njira zamakono zimenezi, apa Dziwani kuti standby mowa mode mphamvu chinkhoswe mwapadera mu purosesa chapakati. Pamene masensa moyandikana kudziwa njira ya kanjedza kapena chala, kuwonetsera ndi anazimitsa pa, omwe amasonyeza zambiri panopa. Zonsezi amachepetsa pafupifupi mowa mphamvu chida, pamene kuwonjezeka batire pulogalamu yowongolera.

Features ntchito ya ntchito njira zosiyanasiyana

Kunyumba zochita zokha moyandikana kudziwika Mbali ndinalandira ambiri kwambiri. masensa moyandikana ntchito kuti athe tebulo nyali, kutsegula mavavu makina ochapira, pamene m'munda zochita ndi manja a munthu; anasonyeza refrigerators ndi mauvuni mayikirowevu adzakhala wofooka mpaka sadzabwera pafupi dzanja malangizo. Okonzeka ndi nchito imeneyi, ndipo latsopano dongosolo kunyumba zochita zokha. Kukhudza zowonetsera, ntchito pofuna kuchepetsa zipangizo banja ndi kuyatsa, kukhazikitsa kuti atumikire monga digito chithunzi chimango. Koma mwamsanga pamene ali pafupi anthu ena uwoneka kwa iwo mwamsanga mabatani kulamulira. Zokwanira chidwi luso ndi moyandikana sensa pa foni yanu. Kodi ndi bwino kudziwa za njira imene kuzindikira chikuchitika.

njira kudziwika kwa approximating

Pali njira, imene inductive, resistive, kuwala, capacitive, kuwala ndi acoustical. Aliyense ali ndi ubwino ndi kuipa. Kusankha luso ndi zimadalira mtengo ndi chomasuka ntchito ndi izo. Taganizirani moyandikana sensa pa foni - zikuthandizani kumvetsa zinthu zina. Nthawi zambiri, capacitive moyandikana masensa ntchito. Mfundo awo a ntchito ndi wosavuta. Kachipangizo ochititsa ndi thereto abwino, zobisika pansi wosanjikiza wapadera zozitetezera. Awiri kuchititsa mchitidwe umakhala pafupi wina ndi mnzake, ndi zina m'gulu capacitance amene angakhalepo pakati wosanjikiza wa conductive ndi grounding PAD wa kachipangizo yokha. Kawirikawiri kuchuluka kwake ndi 10-300 pikafarad.

Pamene kachipangizo ikuyandikira Mwachitsanzo, chala, kusintha dongosolo mphamvu yonse. Izo ntchito kuti azindikire chinthu pafupi ndi kachipangizo sanali nawo.

Kudziwika kusintha capacitance

Monga mmene zolondola ndi odalirika osakhala kukhudzana sensa ntchito, izo zikudalira pa kukhulupirika muyeso wa mphamvu wosinthika mwa dongosolo. Kuti zimenezi zitheke, izo zachitika angapo njira kuphatikizapo odziwika njira zitsulo mlandu kutengerapo, motsatizana chiyerekezo, mogwirizana chotengera ndi njira Sigma-ankadziwana. Nthawi zambiri awiriwo ntchito. Onse ntchito anazimitsa capacitance dera ndi kunja chingwe capacitor.

The njira ya approximations motsatizana

Pankhaniyi, adzapereke imagwiridwa ndi anazimitsa capacitor dera. Popeza capacitor voteji umagwiritsidwa ntchito comparator kudzera otsika chikudutsa fyuluta, kumene poyerekeza ndi voteji pakuyenerera. kauntala A, clocked ndi jenereta ndi, yatsekedwa mwa mbendera comparator linanena bungwe. Processing tenepa ikuchitika kwa kachirombo makamaka kachipangizo. negligible chiwerengero cha zigawo kunja wofunikila njira approximations motsatizana. Pankhaniyi, ntchito dera si bwanji crosstalk pa unyolo okwanira.

Ubwino ndi kuipa kuzindikira luso

Moyandikana sensa Android, monga ena, ali peculiarities ena. Ubwino mu nkhani iyi ndi izi:

- ndithu zone kudziwika;

- digiri yapamwamba ya tilinazo;

- wachibale kupezeka mu mawu a mitengo, chifukwa yopanga masensa ndi wotchipa kwambiri zigawo zikuluzikulu - mkuwa, tini okusayidi film, ndi indium inki, kunja waya kachipangizo;

- Small kukula;

- ndi ntchito zake zosiyanasiyana za kamangidwe;

- kutentha mutendele;

- luso ntchito ndi ❖ kuyanika osiyana sanali conductive Mwachitsanzo, galasi thicknesses osiyana;

- durability ndi mkulu kudalirika.

Pali njira imeneyi ili kuipa:

- amafotokozera cholinga kukhala conductive, ndiye adzatha kudziwa njira; koma dzanja Mwachitsanzo, mu mogwirizana labala, ndipo sangathe kupeza;

- kupeza kumagwa chinthu conductive zingachititse kuti dongosolo adzakhala recalculate ndi capacitance parasitic kuti kuwerengera kusintha chifukwa cha chinthu. Izi nthawi zambiri chifukwa cha zizindikiro zonama m'tsogolo Komabe, calibration moyandikana sensa adzachotsa n'zongochedwetsana izi;

- capacitive kudziwika njira ntchito kotero kuti pamene osiyanasiyana ntchito yake, pali zitsulo zinthu, osiyanasiyana yafupika.

Loko iPhone 4 chophimba

The kachipangizo moyandikana ukugwira ntchito kuti amalola kuletsa chophimba yamakono pa foni kuteteza mwangozi makina kiyi. Pali ntchito yapadera kuti n'zotheka logwirana chophimba basi swiping pa izo ndi dzanja. Ndi zimenezi, muyenera akanikizire ndi hardware batani.

calibration

Nthawi zambiri, mapulogalamuwanso akukumana ndi vuto zosasangalatsa, pamene loko chophimba pamene akulankhula si ikuchitika. Ndipo chigweranso kuwonetsera si kuyatsa pambuyo kuitana watha, nchifukwa chake foni si zosakhoma. Mwachitsanzo, Nokia moyandikana sensa sizikuyenda bwino. Pofuna kuthetsa vutoli, lifunika calibrated. Childs, opanga kwambiri ntchito mapulogalamu apadera Mwaichi, sipangakhalenso dawunilodi pa webusaiti boma.

Atsopano mabaibulo Android 4, ntchito calibration ali Integrated mu menyu. Kuti tichite zimenezi, muyenera fufuzani makonda, kuyang'ana kwa zenera, ndiyeno kusankha moyandikana sensa calibration. Pambuyo kutseka kachipangizo dzanja ayenera kukhala zenera limapezeka, dinani bwino. Nthawi zina analola calibration ndipo popanda kachipangizo kutsekedwa.
