Ubwino wa Masewera Ogwirizira

Zomverera zimagwiritsidwa ntchito m'njira zosiyanasiyana zamagetsi kuyambira magwiritsidwe ntchito ndi ma pinestics; Kuwongolera madzi, ma hydraulocs am'manja ndi magalimoto otsika mtengo; mapampu ndi compressors; Zowongolera mpweya ndi firiji kuti zibzale upangiri ndi oyendetsa. Amachita mbali yofunika kwambiri pakuwonetsetsa kuti kupsinjika kwa dongosololi ndi kovomerezeka ndikuthandizira kukonza ntchito zoyenerera. Kutengera ndi kuyika kwa dongosolo ndi kachitidwe, pali maubwino osiyanasiyana pogwiritsa ntchito analog ndi masensa opaka digito.

Mukamagwiritsa ntchito digito ndi analogKuponya masensaM'mapangidwe a dongosolo

Ngati dongosolo lomwe lilipo limakhazikitsidwa ndi analog contract, imodzi yabwino yogwiritsa ntchito sensor ya Anallog ndikusavuta kwake. Ngati chizindikiro chimodzi chokha chimafunikira kuyeza ndondomeko yamphamvu m'munda, sensor ya analog yophatikizidwa ndi sensor (pomwe magetsi amagetsi angafunike njira yosavuta yothandizira, kodi sensor yolimba ndiyo yankho labwino kwambiri. Kwa machitidwe omwe safuna nthawi yoyankha kwambiri kuposa 0,5ms, kupotoza kupanikizika kwa digito kuyenera kuganiziridwa, pamene asinthitsa ma netrict ndi zida zingapo za digito ndikupanga dongosolo lalikulu.

Nthawi yoyenera yolingalira zotsekemera kutsata kupanikizika pazithunzi za Aalog ndikukweza zinthu zomwe zimaphatikizapo microchips. Microchips yamakono tsopano ndi yotsika mtengo komanso yosavuta pulogalamu, komanso kuphatikiza kwawo magawo monga masekondi okakamizitsa ndi kukonza njira. Izi zimapulumutsa ndalama zomwe zingalepheretse, monga sensor ya digito imatha kusinthidwa kudzera mu pulogalamuyi m'malo mosintha chinthu chonse.

Kupanga kwa plug ndi-preser ndi zazifupi kutalika kwa sewero la digito kumasinthira kusintha kwa dongosolo ndikuchepetsa mtengo wonse wogwiritsira ntchito ma digito. Pamene sensa ya digito ikaphatikizidwa ndi tracker tracker, imatha kupeza bwino ndikuwunika njira zakutali zakutali panthawi yeniyeni.

Ma hudi ya digito amapereka zabwino zambiri monga kugwiritsa ntchito mphamvu zochepa, phokoso lamagetsi, matenda a sensor, komanso kuwunikira zakutali.

Ubwino wa Masewera Ogwirizira

Wosuta akangoyang'ana ngati sensanalog kapena sensor yotsatira ya digito ndiyabwino kugwiritsa ntchito, kumvetsetsa zina zopindulitsa kwa digito kumathandiza kukonza chitetezo chambiri, kuchita bwino komanso kudalirika.

Kufanizira kosavuta kwa madera omwe aphatikizidwa (i 2 c) ndi mawonekedwe a serifaral (spi)

Ma protocol awiri a digito omwe amagwiritsidwa ntchito pogwiritsa ntchito mafakitale ogwiritsira ntchito masitepe (i 2 c) ndi mawonekedwe a serifaral mawonekedwe (SPI). I2C ili bwino kwambiri pamaukonde ambiri chifukwa mawaya ochepa amafunikira kukhazikitsa. Komanso, I2C imalola maukonde angapo a Master / Akapolo, pomwe spi imangolola mbuye / kachigawo ka akapolo angapo. SPI ndi njira yabwino yothetsera maulendo osavuta komanso othamanga kwambiri komanso kusinthidwa monga kuwerenga kapena kulemba makhadi a SD kapena kujambula zithunzi zojambulira.

Kutulutsa zizindikiro ndi sensor

Kusiyana kofunikira pakati pa analog ndi masensa ogwiritsira ntchito digito ndi chizindikiro chimodzi chokha chimapereka chizindikiro chimodzi chokha chimapereka kawiri kapena kupitilira apo, zizindikilo za sensor. Mwachitsanzo, munthawi ya cylinder cylinder, zambiri zowonjezera zimakulitsani chizindikiro chokwanira, kulolanso kuchuluka kwa mankhwalawa kuti muwerengenso, kuphatikizaponso kudalirika kokha, komanso zolakwika zenizeni, ndikuchepetsa kukonzanso.

Ma deta matenda amapereka mwatsatanetsatane wa sensor, monga kuti chinthu cha sensor chimawonongeka, ngakhale magetsi amagetsi ndi olondola, kapena pali zomwe zimasinthidwa mu sensor yomwe ingapezeke. Ma deadestic deta kuchokera masensa a digito amatha kubweretsa zisankho zabwino akamakambirana kuposa ma exy sapereka mwatsatanetsatane zokhudzana ndi zolakwika zakunja.

Phindu linanso la maseweredwe apagitalo ndikuti ali ndi ma alarm omwe amatha kuchenjeza ogwiritsa ntchito mbali zina ndi kuthekera kuwongolera nthawi ndi nthawi yowerengera mphamvu. Chifukwa kuphatikizira kwapa digito kumapereka kuchuluka kwa zotulutsa ndi matenda ozindikira, dongosolo lonseli ndi lamphamvu komanso labwino, chifukwa chidziwitsocho chimapereka makasitomala omwe amawunikanso kugwiritsa ntchito makina a dongosololi. Kuphatikiza pa kukula kwa mphamvu ndi luso lozindikira, kugwiritsa ntchito ma secherast kupachitsa kumathandiziranso kukula ndi kukhazikika kwa ntchito yamafakitale ya zinthu (iit) machitidwe ndi mapulogalamu akuluakulu.

phokoso lachilengedwe

Madera opangira magetsi okhala pafupi ndi motars, zingwe zazitali, kapena magwero oyenda opanda zingwe amatha kupanga zovuta zomwe zimapangitsa kuti zisokoneze zigawo zikuluzikulu monga masentimita. Pofuna kupewa zosokoneza zamagetsi (EMI) m'makona a Analog, kapangidwe kakufunika kuphatikiza zizindikiro zoyenera monga

Zinyalala zachitsulo zokhala ndi zamagetsi kapena zowonjezera zamagetsi, monga phokoso lamagetsi lingapangitse kuwerengera zabodza. Zotuluka zonse za analog ndizotengeka kwambiri ndi EMI; Komabe, kugwiritsa ntchito ma 4-20Ma analog kungathandize kupewa izi.

Mosiyana ndi izi, masekondi ogwirira ntchito digital samatengeka ndi phokoso losavuta pazinthu zachilengedwe kuposa momwe anakon amafunikira, motero amapanga chisankho chabwino chogwiritsa ntchito EMI ndipo amafunikira chotulutsa china 4-20MA. Tiyenera kudziwa kuti mitundu yosiyanasiyana ya masentimita a digito imapereka digiri yosiyanasiyana ya EMI, kutengera mawonekedwe ogwiritsira ntchito (SPI) pa wotsutsa. Kwa machitidwe omwe amafunikira zingwe zazitali mpaka 30m, zojambula (posankha zotchinga) kapena zidziwitso za Digital ndizofunikira kwambiri pazinthu za I2C ndi seri).

Kuteteza deta pogwiritsa ntchito cheke cha cyclic

Ma digito amapereka mwayi wophatikiza CRC m'chip kuti athandizire kuti makasitomala azidalira chizindikiro. Cryc ya deta yolumikizirana ndi yowonjezera pakuwona kukhulupirika kwamkati, kulola kuti wogwiritsa ntchito kutsimikizika wa sensor, omwe amapangika pafupi ndi njira zosinthira. Pankhaniyi, pali chiopsezo chowonjezereka cha phokoso losokoneza chip chip ndi kupanga masamba omwe angasinthe uthenga wolankhulana. Chr pa umphumphu woyenera umphumphu womwe ungateteze kukumbukira kwamkati ndi chivundi chotere ndikukonzanso ngati kugwirizanitsa kwa sensor, monganso kulumikizana kwa senso, monga mtambo, kapena wolamulira. CRC imathandiza izi ndipo imapereka kusinthanso kwa wopanga. Kuphatikiza pa zovomerezeka za data, opanga ena amawonjezera magetsi ambiri kuti apanduke phokoso losiyana ndi WiFi, Bluetooth, GSM, ndi asm kuti ateteze kuvomerezeka kwa data.

Sensori ya digito kuntchito imathandizira ma network amadzi

Kutayika kwamadzi chifukwa cha kutaya, kusokonekera kolakwika, kugwiritsa ntchito mosavomerezeka kapena kuphatikiza atatuwo ndi zovuta zomwe zimapezeka nthawi zonse pamasamba akulu ogulitsa madzi ambiri. Kugwiritsa ntchito mitundu yotsika yotsika ya digito ya digito ya digiri ya digiriti yogawa madzi ndi njira yothandiza komanso yotsika mtengo yopanga ma network am'madzi ndikulola kuti zitheke ndikupeza madera omwe kutaya kwadzidzidzi kumachitika.

Ikagwiritsidwa ntchito ku malowa a netiweki yonse, kuponderezana kwa digito kungathandize kuzindikira malo osayembekezereka madzi, potengera kusokoneza bwino ndikuwongolera mphamvu.

Ma tony amayang'anitsitsa kuti mapulogalamuwa amakhala osindikizidwa ku iP69k kapena moder kuti apereke makasitomala kukhala osinthika. Pofuna kupewa madzi kuti asalowe mu moyo wonse wa pulogalamuyi, opanga sensor ena amagwiritsa ntchito kulumikizana kwa galasi. Chisindikizo cha-zitsulo ndi madzi osanjikiza ndipo amapanga chisindikizo chambiri pa sensor, chomwe chimathandiza sensor kukwaniritsa IP69K. Kusindikiza uku kumatanthauza kuti sensor nthawi zonse imatha kuyeza kusiyana pakati pa chinthucho pantchito yofunsira ndi mpweya mozungulira, kupewa kugwera.

Kuwongolera kwa Magesi Okhazikika

Ma tony opindika amasewera magawo osiyanasiyana powunikira ndi kutumiza kwa mpweya wopanikizika ndi mipweya yamankhwala mu zogawana pafoni. Mumitundu iyi yamapulogalamu, ma tyy amalimbikitsa kuwongolera compressorr kuwongolera, kuphatikizapo kusinthika kwa masitepe a digito. Izi zimathandiza kuti opanga makina aziyandikira kwambiri pazomwe mungagwiritse ntchito.

Ngakhale pali makonzedwe ena omwe ali oyenera kugwiritsa ntchito ma tony a analog, makampani ochulukirapo 4.0 amapindula pogwiritsa ntchito anzawo a digito. Kuchokera ku chitetezo cha EMI Mapangidwe a secher a rocy monga iP69k kuwerengetsa, ma sekondale owonjezera a data a EMI ateteza moyo ndikuchepetsa zolakwitsa zomwe zingachitike.
