Batri Yabwino Kwambiri ya Zipangizo za IoT
Zipangizo za intaneti ya Zinthu (IoT) tsopano zilipo m'mbali zosiyanasiyana za moyo: nyumba zanzeru, mafakitale, ulimi wolondola, chisamaliro chaumoyo, komanso mizinda yanzeru. Kumbuyo kwa zosavuta komanso zodziyimira pawokha zomwe zimaperekedwa, pali gawo limodzi lomwe nthawi zambiri limatsimikizira kupambana kwa kukhazikitsa kwa IoT m'munda: batire. Zipangizo za IoT nthawi zambiri zimafunika kuti zigwire ntchito kwa nthawi yayitali, mokhazikika, komanso mosamalitsa kwambiri—nthawi zambiri zimayikidwa m'malo ovuta kufikako. Chifukwa chake, kusankha batire yabwino kwambiri yazipangizo za IoT sikungokhudza kusankha "mphamvu yayikulu," koma yomwe ikugwirizana bwino ndi mawonekedwe amagetsi, malo ogwirira ntchito, komanso nthawi ya moyo wa chipangizocho.
Chifukwa chiyani kusankha mabatire a IoT ndikofunikira?
Ma node ambiri a IoT amagwira ntchito mwanjira yapadera: amagona nthawi zambiri, kenako amadzuka kwakanthawi kuti ayeze masensa ndikutumiza deta. Mphamvu yamagetsi panthawi yogona imatha kukhala yaying'ono kwambiri (ma microampere), pomwe panthawi yotumizira ma wailesi imatha kuwonjezeka kwambiri (makumi mpaka mazana a ma milliamperes) kwa kanthawi kochepa. Kuphatikiza apo, IoT nthawi zambiri imagwirizanitsidwa ndi ma protocol ogwiritsira ntchito mphamvu monga BLE, Zigbee, LoRaWAN, NB-IoT, kapena LTE-M. Zinthu zonsezi zimapangitsa kuti mawonekedwe a batri—monga voltage yoyesedwa, kukana kwa surge, kudzitulutsa, ndi magwiridwe antchito kutentha kwambiri—akhale ofunikira kwambiri kuposa nambala ya mAh yokha.
Makhalidwe Abwino Kwambiri a Batri a IoT
Musanasankhe mtundu wa batri, ganizirani izi:
1. Kuchuluka kwa mphamvu ndi kukula kwake
Nthawi zambiri IoT imafuna mabatire ang'onoang'ono komanso okhalitsa. Kuchuluka kwa mphamvu kumathandiza kukulitsa moyo wa batri popanda kuwonjezera kukula kwake.
2. Kudzitulutsa m'thupi
Zipangizo zomwe zapangidwa kuti zigwire ntchito kwa zaka 2-10 zimafuna mabatire omwe amatha kudzitulutsa okha.
3. Mphamvu yamagetsi yapamwamba kwambiri
Gawo la wailesi limafuna mphamvu yamagetsi yapamwamba kwambiri panthawi yotumiza uthenga. Batire ikalephera kugwira ntchito ingayambitse chipangizocho kuyambiranso kapena kulephera kutumiza uthenga.
4. Kutentha kogwirira ntchito
Masensa akunja, zipangizo zamafakitale, kapena maunyolo ozizira amafunikira mabatire omwe amakhalabe olimba pa kutentha kochepa komanso kokwera.
5. Chitetezo ndi kukhazikika kwa mankhwala
Pa zipangizo zomwe zimayikidwa m'nyumba kapena m'malo opezeka anthu ambiri, chitetezo cha mabatire n'chofunika kwambiri—makamaka m'makampani omwe nthawi zambiri amatenthedwa ndi kutentha.
6. Mtengo ndi kupezeka
Pa kukula kwa zinthu, mtengo, kusavuta kugula, ndi kukula kofanana (AA, AAA, ndalama zachitsulo, thumba) zimakhudza mtengo wonse wa dongosololi.
Mitundu ya Mabatire Omwe Amagwiritsidwa Ntchito Kwambiri mu IoT

Yoyenera: zipangizo zanzeru zapakhomo zomwe zitha kuchajidwa nthawi zonse, kapena zipangizo zophunzitsira komanso zodzipangira tokha.
Malangizo Onse: "Zabwino Kwambiri" Zimadalira Zochitika
Kuti zinthu zikhale zosavuta, nayi kalozera wosankha kutengera zosowa zofala kwambiri:
1. Yembekezerani zaka 5-10 popanda kuyika batri m'malo ena
Sankhani Li-SOCl₂ (nthawi zambiri imaphatikizidwa ndi capacitor/HLC kuti ipereke mphamvu zambiri).
2. Zipangizo zazing'ono, kugwiritsa ntchito kochepa kwambiri, kutumiza kosachitika kawirikawiri (ma beacons a BLE, masensa osavuta)
Sankhani selo ya ndalama ya Li-MnO₂ (CR2032/CR2450), yokhala ndi kapangidwe ka firmware kotsika mtengo kwambiri.
3. Pali kubwezeretsanso mphamvu (USB/solar), kufunikira kutumiza mauthenga pafupipafupi kapena kugwiritsa ntchito netiweki yam'manja
Sankhani Li-ion/Li-Po. Onetsetsani kuti chitetezo ndi kapangidwe koyenera ka chaji zimatetezedwa.
4. Mukufuna batire yotha kuchajidwanso yomwe ndi yotetezeka komanso yolimba (ya mafakitale, yakunja, yotentha)
Taganizirani za LiFePO₄.
5. Mtengo wake ndi wovuta kwambiri ndipo chipangizochi chimapezeka mosavuta kuti chisinthidwe ndi batri.
Alkaline ikhoza kukhala yokwanira, koma yesani kuyesa mphamvu yamagetsi ndi kutentha.
Malangizo Opangira Mabatire a IoT Okhalitsa Kwambiri
Ngakhale batire yabwino kwambiri imatha kutha msanga ngati chipangizocho sichinapangidwe bwino. Nazi malangizo othandiza:
- Konzani bwino nthawi yogwira ntchito: onjezerani nthawi yogona, chepetsani nthawi yogwira ntchito.
- Gwiritsani ntchito chowongolera chogwira ntchito bwino: sankhani buck/boost yokhala ndi mphamvu yochepa yoziziritsa.
- Chepetsani kutumiza: kutumiza deta nthawi ndi nthawi, kapena pazochitika.
- Gwiritsani ntchito ma capacitor kuti muzitha kuphulika: zimathandiza pamene wailesi ikufunika mphamvu yapamwamba kwambiri.
- Ganizirani kutentha: mphamvu yogwira ntchito ya batri imatha kutsika kwambiri kutentha kochepa.
- Kuyesa zenizeni: kuyerekezera kokha sikokwanira; chitani mayeso a momwe munthu amagwiritsira ntchito panthawi yogona komanso potumiza.
Kutseka
Batire yabwino kwambiri ya zida za IoT ndi yomwe ikugwirizana bwino ndi zosowa zawo: nthawi yogwira ntchito, momwe magetsi amagwiritsidwira ntchito, kutentha kwa malo, ndi njira zosamalira. Pazida za IoT zomwe zimakhala nthawi yayitali zomwe zimakhala zovuta kuzifikira, Li-SOCl₂ nthawi zambiri ndiye chisankho chomwe chimakondedwa. Pazida zomwe zimachajidwanso zomwe zimakhala ndi mphamvu zambiri, Li-ion/Li-Po kapena LiFePO₄ zimatha kupereka kusinthasintha kwakukulu. Pakadali pano, maselo a ndalama za lithiamu ndi oyenera zida zazing'ono, zogwira ntchito bwino kwambiri, ndipo alkaline imakhalabe yofunikira pakugwiritsa ntchito kosavuta komanso kotsika mtengo.
Mwa kusankha njira yoyenera ya batri pokonza zida ndi firmware, zida za IoT zimatha kugwira ntchito nthawi yayitali, mokhazikika, komanso modalirika - kuchepetsa ndalama zogwirira ntchito pomwe zikukweza zomwe ogwiritsa ntchito akukumana nazo.
