Vanopindura zvechimbichimbi sevanodzima moto, maamburenzi nemapurisa vanovimba neredhiyo nzira mbiri dzekutaurirana kana hupenyu nemidziyo zviri panjodzi.Muzvivako zvakawanda izvi hazvisi nyore nguva dzose.Masaini eredhiyo mukati mezvivakwa anowanzo kubatwa kana kuvharika nezvimiro zvakakura zvepasi pevhu, kongiri kana zvivakwa zvesimbi.
Pamusoro pezvo, zvimiro zvakagadzirirwa kugadzira zvimiro zvakatsiga, senge yakaderera-emissivity mahwindo mahwindo, attenuate masaini kubva paruzhinji kuchengetedza redhiyo.Kana izvi zvikaitika, zviratidzo zvisina simba kana zvisipo zvinogona kugadzira redhiyo "nzvimbo dzakafa" munzvimbo dzekutengesa, izvo zvinogona kukanganisa kurongeka uye kuchengetedzeka pakati pevanotanga kupindura panguva yenjodzi.
Somugumisiro, mitemo yakawanda yekuchengetedza moto ikozvino inoda kuiswa kweEmergency Response Communication Enhancement Systems (ERCES) yezvivako zvitsva uye zviripo zvekutengeserana.Aya masisitimu epamberi anokudza chiratidzo mukati mezvivakwa, achipa yakajeka nzira mbiri dzeredhiyo kutaurirana pasina nzvimbo dzakafa.
"Dambudziko nderekuti vanotanga vanopindura vanoshanda zvakasiyana, izvo zvinosiyana kubva kuguta neguta, saka michina yeERCES yaifanira kugadzirwa kuti ikwidziridze nzira dzakatarwa chete," akadaro Trevor Matthews, maneja wedhipatimendi rewireless revatengesi Cosco.kudzivirira moto.Kupfuura makore makumi matanhatu ekutengesa moto kudzvinyirira uye hupenyu hwekuchengetedza masisitimu.Kwemakore mana apfuura, kambani yanga ichipa masevhisi ekumisikidza ehunyanzvi intercom masisitimu.
Matthews akawedzera kuti magadzirirwo akadai anowanzo sanganisira ERCES kuseta kudzivirira masaini kubva mukukanganisa mamwe ma frequency uye kudzivirira kunetsana neFCC, iyo inogona kubhadharisa faindi hombe kana ikatyorwa.Pamusoro pezvo, makambani anowanzo fanirwa kuisa iyo system yese asati aburitsa chitupa chekomisheni.Kuti usangane nenguva dzakasimba, vanoisa vanovimba neOEM ERCES kukurumidza kuendesa kwezvikamu zvehurongwa.
ERCES yemazuva ano iripo iyo "yakagadzirirwa" neOEMs kune chaiyo inodiwa UHF uye/kana VHF chiteshi.Makondirakiti anogona kuzowedzera kukwirisa midziyo yemumunda kune chaiyo bandwidth kuburikidza nekusarudza chiteshi tuning.Iyi nzira inobatsira kutevedzera mitemo yese uye zvinodiwa, uku ichideredza mutengo wakazara uye kuoma kwekuiswa.
ERCES yakatanga kuunzwa mu2009 International Building Code.Mitemo ichangoburwa yakaita seIBC 2021 Chikamu 916, IFC 2021 Chikamu 510, NFPA 1221, 2019 Chikamu 9.6, NFPA 1, 2021 Chikamu 11.10, uye 2022 NFPA 1225 Chitsauko 18 chinoda kuti zvivakwa zvese zvechimbichimbi zvive nerubatsiro rwechimbichimbi.kuvharwa kwekutaurirana.
Iyo ERCES sisitimu yakabatana pamusoro pemhepo uye inoshandiswa nevaisimi vachishandisa padenga rekutungamira antenna kukwidziridza network yenhare dzeredhiyo dzekuchengetedza veruzhinji.Iyi antenna inobva yabatanidzwa kuburikidza necoaxial tambo kune bi-directional amplifier (BDA) iyo inosimudzira mwero wechiratidzo kuti ipe kuvharika kwakakwana mukati mechivakwa kusangana nehupenyu hwekuchengetedza zviyero.Iyo BDA yakabatana neDistributed Antenna System (DAS), network yeantenna madiki akaiswa mukati mese chivakwa anoita seanodzokorora kuvandudza kuvharwa kwemasaini munzvimbo dzese dziri kure.
Muzvivakwa zvakakura zve 350,000 square tsoka kana kupfuura, akawanda amplifiers anogona kudikanwa kuti ape yakakwana simba rechiratidzo mukati mehurongwa.Pamusoro penzvimbo yepasi, mamwe maitiro akadai sedhizaini yekuvaka, mhando yezvivakwa zvekuvaka zvinoshandiswa, uye density yekuvaka zvakare inokanganisa huwandu hwemaamplifiers anodiwa.
Muchiziviso chechangobva kuitika, COSCO Moto Dziviriro yakapihwa basa rekuisa ERCES uye yakabatanidzwa kudzivirira moto uye masisitimu ekuchengetedza hupenyu panzvimbo hombe yekugovera DC.Kuzadzisa zvinodiwa nekanzuru, Cosco Fire yaida kuisa ERCES yakarongedzerwa kuVHF 150-170 MHz yedhipatimendi remoto uye UHF 450-512 yemapurisa.Chivako chinogashira chitupa chekutumwa mukati memavhiki mashoma, saka kuiswa kunofanirwa kuitwa nekukurumidza sezvinobvira.
Kurerutsa maitiro, Cosco Fire yakasarudza Fiplex kubva kuHoneywell BDA uye fiber optic DAS masisitimu kubva kune anotungamira mugadziri wekutengesa kuvaka moto kudzivirira uye hupenyu hwekuchengetedza masisitimu.
Iyi inoenderana uye yakasimbiswa sisitimu yakagadzirirwa kupa yakavimbika yepamusoro RF kuwana uye isina ruzha kufukidzwa, inosimudzira maviri-nzira mbiri RF chiratidzo chesimba mukati mezvivakwa, tunnel uye zvimwe zvimiro.Iyo sisitimu yakagadzirirwa kuzadzisa zvinodiwa zveNFPA neIBC/IFC zviyero uye UL2524 2nd edition zvinyorwa.
Sekureva kwaMatthews, chinhu chakakosha chinosiyanisa ERCES kubva kune vamwe kugona kweOEM "tune" mudziyo kuchiteshi chavari kushandisa vasati vatumira.Makondirakiti anogona kuzowedzera kukwidziridza iyo BDA RF tuning pasaiti kuti iwane iyo chaiyo frequency inodiwa kuburikidza nechiteshi kusarudza, firmware, kana inogadziriswa bandwidth.Izvi zvinobvisa dambudziko rekufambiswa kwebroadband munzvimbo dzakatsvikinyidzana dzeRF, izvo zvingangokonzeresa kupindira kwekunze uye zvichikonzera faindi yeFCC.
Matthews anonongedza mumwe mutsauko pakati peFiplex BDA uye mamwe madhijitari masaini amplifiers: maviri-bhendi sarudzo yeakazvitsaurira UHF kana VHF modhi.
"Kusanganiswa kweUHF neVHF amplifiers kunorerutsa kuisirwa nekuti unongova nepanera rimwe chete pane maviri.Inoderedzawo nzvimbo inodiwa yemadziro, simba rinodiwa uye zvingangoitika zvekukundikana.Kuongorora kwegore kuri nyore zvakare,” anodaro Matthews.
Nechinyakare ERCES masisitimu, makambani ekuchengetedza moto nehupenyu anowanzoda kutenga zvinhu zvechitatu-bato kuwedzera kune OEM kurongedza.
Nezve mashandisirwo apfuura, Matthews akaona kuti “zvakaoma kuwana zvechinyakare zveERCES kuti zvishande.Takazofanira kutendeukira kune wechitatu kuti titore [signal] mafirita ataida nekuti OEM yanga isingaape."akataura kuti nguva yekugamuchira midziyo iyi mwedzi, uye anoda mavhiki.
"Vamwe vatengesi vanogona kutora mavhiki masere-14 kuti vagamuchire amplifier," Matthews akatsanangura."Zvino isu tinogona kuwana amps echinyakare toiisa neDAS mukati memavhiki mashanu kusvika matanhatu.Iyi ishanduko yevanoita makondirakiti, kunyanya kana hwindo rekuisa rakamanikana,” Matthews anotsanangura.
Kune mugadziri, mugadziri wezvivakwa, kana engineering femu achishamisika kana ERCES ichidikanwa pachivako chitsva kana chiripo, danho rekutanga ndere kubvunzana nekambani yekudzivirira moto / hupenyu inogona kuita ongororo yeRF yenzvimbo.
Zvidzidzo zveRF zvinoitwa nekuyera downlink/uplink signal level mu decibel milliwatts (dBm) vachishandisa midziyo yekuyeresa yakakosha.Mhedzisiro yacho ichaendeswa kumutumbi une hutongi hwekuona kana chirongwa cheERCES chichidiwa kana kuti kuregererwa kwakakodzera.
“Kana ERCES ichidikanwa, zviri nani kuti muyedze pachine nguva kuti muderedze mutengo, kuoma, uye nyore kuisa.Kana chero nguva chivakwa chikatadza ongororo yeRF, chingave chivakwa ichi 50%, 80%, kana 100% yakakwana, isai ERCES system, saka zvakanaka kuti muedze iyo isati yanyanya kunetsa,” akadaro Matthews.
Akataura kuti panogona kuve nemamwe matambudziko pakuita bvunzo dzeRF muzvivakwa zvakaita sematura.ERCES inogona kunge isingadikanwi mudura risina chinhu, asi simba rechiratidzo munzvimbo dzenzvimbo yacho rinogona kuchinja zvakanyanya mushure mekuiswa kwe racks nemimwe michina uye kuwedzerwa kwezvinhu.Kana iyo system ikaiswa mushure mekunge imba yekuchengetera yatove kushandiswa, kambani yekuchengetedza moto nehupenyu inofanirwa kushanda ichipfuura zvivakwa zviripo uye chero vashandi.
“Kuisa zvikamu zveERCES muchivako chakabatikana kwakaoma zvikuru kupfuura mudura risina chinhu.Vanoisa vangangoda kushandisa hoist kuti vasvike padenga, tambo dzakachengetedzeka, kana kuisa antennas, izvo zvakaoma kuita muchivakwa chinoshanda zvizere, ”Matthews.akadaro tsanangura.
Kana kuiswa kweiyo system kuchikanganisa kupihwa kwezvitupa zvekomisheni, bhodhoro iri rinogona kunonoka zvakanyanya kuitwa mapurojekiti.
Kuti udzivise kunonoka uye nyaya dzehunyanzvi, vanogadzira zvivakwa zvekutengesa, vagadziri vezvivakwa uye mafemu einjiniya vanogona kubatsirwa kubva kune nyanzvi makondirakiti kujairana neERCES zvinodiwa.
Nekukurumidza kuendeswa kweERCES yepamberi yakagadziridzwa neOEM kune inodiwa RF chiteshi, kontrakta anokwanisa anogona kuisa uye kuwedzera optimize michina yeakananga ma frequency enzvimbo yekusarudza chiteshi tuning.Iyi nzira inomhanyisa mapurojekiti uye kutevedzera, uye inovandudza chengetedzo munjodzi.
