Wired vs. Wireless Battery Monitoring System : Ndeipi Iri Nani?
Iyo kure bhatiri yekutarisa yakakosha kune ako mashandisirwo. Pasina mhinduro yakavimbika yekutarisa, haugone kuziva nekukurumidza kana kukanganisa kwebhatiri uye tsaona zvikaitika kunze kwekunge uine vashandi panzvimbo 24/7. Kunyangwe ipapo, iwe uri panjodzi yekutarisisa nyaya dzemidziyo kana shanduko yemamiriro isingagone kuonekwa pasina ma sensor akakodzera uye bhatiri monitoring system yakaiswa.
Nepo mabhenefiti ekushandisa ari kure bhatiri yekutarisa system akajeka, sarudzo yekushandisa isina waya kana wired sensors ine system haina kujeka. Wired uye wireless sensors zvese zvine zvazvakanakira uye zvazvakaipira. Kuziva zvidikanwi zvechikumbiro chako kuchakubatsira kuti usarudze kuti ndeipi sarudzo yakakodzera purojekiti yako. Hezvino zvinhu zvishoma zvekufunga nezvazvo:
Tora mufananidzo wese weese mabhatiri ekutarisa masisitimu
Iyo iri kure bhatiri yekutarisa system (BMS) yakakosha kune kutarisa kwebhatiri mukushanda. A smart BMS yaiona mhando yebhatiri, mavoltages, tembiricha, huwandu, mamiriro ekuchaja, mashandisiro emagetsi, kutenderera kwechaji, uye humwe hunhu. Inogona kuwedzera kushandiswa kwakaringana kwebhatiri uye kuderedza njodzi yekukundikana kwesimba.
Nekudaro, iwe unogona chete kuita iyo yakawanda yebhatiri yekutarisa masisitimu nekuita sarudzo yakanaka pakati peiyo wired & isina waya. Naizvozvo, ngationgororei muhurukuro:
• Zvimiro zvewaya & isina waya kutaurirana

• Zvakanakira newaya BMS
a. Speed
Kazhinji, mawaya network anononoka pane ane waya. Wireless zviratidzo zvinogona kukanganiswa nyore nemhoteredzo yakapoteredza, yakadai semadziro, pasi, uye makabati munzvimbo, pamwe nekukanganiswa kubva kune zvimwe zvigadzirwa zvemagetsi. Wireless data kutapurirana zvakare kuremerwa kure: iyo iri kure iyo sensors inowanikwa, iyo inoderera kuita.
b. Kuvimbika
Chinyakare wired bhatiri yekutarisa masisitimu anga achichinja uye achiwedzera kwemakumi emakore. Kufambira mberi kwakakosha kwakaitwa kuti kuve nechokwadi kuti vakavimbika zvakanyanya. Vanoshandisa kubatanidza kwemuviri zvakananga uye vanosangana nekukanganisika kushoma kana zvichienzaniswa neasina waya.
c. Battery balance
Wired sensors inogona kuchengetedza kushandiswa kwesimba kugadzikana, kudzivirira kushanduka kunokonzerwa neakasiyana masaini masaini. Nekudaro, ivo vanobatsira kuenzanisa bhatiri uye kuwedzera hupenyu hwebhatiri tambo.
d. Mari-inoshanda
Kuenzaniswa ne wired sensors, ma sensors asina waya anoda yakawedzera wireless transmitter hardware kune imwe neimwe sensor, iyo inotungamira kune yakakwira isina waya mutengo pane wired mhinduro.
e. Maintenance
Mari yevashandi yekuchengetedza ma sensors ane waya kazhinji ishoma pane iya isina waya sensors sezvo yekutanga inoda kugadziridzwa kushoma. Wired sensors inokwanisa kuenderera mberi nekutarisa nekufamba kwemakore, ichidzikisa mitengo yekuona uye kutsiva yakapera kana kukanganisa mayuniti uye mutengo wekuona nyaya dzekubatanidza.
• Zvakaipa pakutarisisa waya
a. Kushaya kufamba
Nekuti iyo wired yekutarisa mhinduro inotsamira pane yemuviri network yetambo, pane kushomeka kwekushanduka kana shanduko dzichida kuitwa. Kuisa tambo patsva kazhinji chinhu chinopedza nguva, zvichienderana nekuti ingani tambo dzinoda kudzoreredzwa uye zvipingamupinyi pakati penzvimbo dzekuwana.
b. Mari yekuisa
Mari yekutanga yekuisa wired monitoring system inogona kunge yakakwira. Matambo aifanira kupinzwa mumadziro, pasi peuriri, uye mune dzimwe nguva kufushirwa. Mari yevashandi inoenderana nemapurojekiti aya inogona kurambidza, uye kana dambudziko rikazoonekwa, kuwana mukana kune tambo idambudziko rakakura.
c. Cable kukanganisa
Pane mamiriro ezvinhu apo cabling yakabatana nemasensor inogona kukuvadzwa, kusunungurwa, kana kubviswa, kungave nekuda kwekukanganisa kwevanhu kana, kazhinji, nekuda kwerimwe basa riri kuitwa pairi. Mune izvi zvisingawanzo zviitiko, kukuvadzwa kune cabling kunogona kukonzera kusapindura kune sensors. Saizvozvo, cabling ingangoda kungobatanidzwazve kana, zvakanyanya, kutsiviwa. Sezvineiwo, Ethernet uye RJ11 cabling hazvidhure, kunyanya kana mutsetse chete kana maviri achitsiviwa.
• Zvakanakira Wireya monitoring sensors
a. Zvakanakira
Imwe yemabhenefiti makuru ekutarisa isina waya kugona kuisa masensa pese painodiwa pasina kumhanya cabling kuburikidza nemadziro, pasi, uye sirin'i, izvo zvinobatsira kudzikisa nguva yekuisa, asi inoda imwe nguva yekumisikidza kero yesoftware.
b. Mobility
Vazhinji vagadziri vemagetsi vasina waya vanobvumira akawanda mawaya masensa kuti abatanidze kune imwechete node. Uyezve, node nyowani kana masensa anogona kuwedzerwa kunetiweki iripo pasina kumhanya yakawedzera wiring kugarisa network kuwedzera.
UPS ichave ichisimbisa dhizaini padanho rekutanga. Kazhinji hapadiwe mamwe ma sensor kune network iripo.
• Zvakaipa zvekutarisisa zvisina waya
a. Deredza hupenyu hwebhatiri
Wireless zviratidzo zvinogona kukanganiswa nekunze kwekunze. Kunyangwe iyo siginecha yakanaka kana yakaipa ichakanganisa zvakananga mashandisirwo emagetsi ega yega sensor uye kuwedzera kusaenzana kwebhatiri.
Wireless sensors zvakare inonzwa kureba. Nekuda kweizvozvo, ma sensors ekureba anowanzo wedzera kuwedzera hupenyu hwebhatiri.
b. Inononoka kumhanya ichienzaniswa newaya yekutarisisa
Paunenge uchiongorora iwo chaiwo-nguva mamiriro emidziyo yakakosha kana zvivakwa, zvakakosha kuti data rifambiswe uye riwanikwe nekukurumidza sezvinobvira. Sezvambotaurwa pamusoro apa, ma sensors asina waya anotapukirwa nekuwedzera latency, kukanganiswa kwechiratidzo, uye kudonhedza kubatana izvo zvinokanganisa kumhanya uye kuenderana kweiyo data rwizi, kunyange kupotsa akakosha maaramu uye kukonzera tsaona.
c. Complex kugadzirisa
Kugadzirisa wireless sensor network kunogona kuve dambudziko rinoramba riripo sezvo mitsva mitsva inowedzerwa kune sensor network. Kuisazve ma sensors uye kuendesa zvakare kana kuvakazve network inodiwa kuchengetedza kumhanya kwekufambiswa kwedata.
d. Nhamba yezviratidzo zvishoma nekuda kwekukanganisa
Wireless data kutepfenyura inofambiswa pamusoro peredhiyo frequency (RF), iyo yagara ichitarisana neyakasiyana-siyana yezvipingamupinyi zvine chekuita nekukanganisa izvo zvinogona kuderedza simba rechiratidzo uye kuderera kwekutapurirana kumhanya. Zvipingamupinyi zvakaita semadziro nemagonhi kana zvimwe zvishandiso zvinoshanda pane imwechete frequency zvinogadzira kusawirirana nekufambiswa kwedata.
Kureba pakati pe sensors uye yavo yekutarisa hub zvakare chinhu chinomisa. Mukaha wakakura wakakwana kana chimiro chakasimba pakati pemapoinzi maviri aya chinogonawo kukonzera kuderedzwa kwedata. Nezvikonzero izvi, vashandisi vazhinji vanowanzo manikidzwa kusashandisa masensa kune yavo yakazara kugona nekudzikisa nguva yekuvhota yedata.
e. Maintenance:
Panyaya yekuchengetedza, sezvo isina waya yebhatiri yekutarisa system ine mukana wepamusoro wekukanganisa, kugadzirisa kwakawanda kunogona kutarisirwa.
Mhedziso
Basa reBMS rakangwara nderekutsvaga bhatiri rakashata uye vashandisi vepamberi-alarm kudzivirira tsaona. Kana bhatiri rakakundikana risingagoni kuziviswa munguva, iyo system haina maturo kutarisa. Naizvozvo, tichifunga nezvese mabhenefiti uye zvipingamupinyi, wired BMS mhinduro isarudzo iri nani.
