He aha te Pūnaha Waea Āwhati, ā, me pēhea te mahi?

Kupu Whakataki

I ngā wāhi ka tūpono te ora o te tangata i te waeatanga roa, ka whakaratohia e ngā pūnaha waea ohorere he ara motuhake hei āwhina i ngā whatunga waea paerewa kāore pea e whakamanahia. E whakamārama ana tēnei tuhinga he aha ēnei pūnaha, he aha i rerekē ai te hanganga mai i te waea noa, me te mahi tahi a ō rātou wāhanga matua hei pupuri i te whakawhitiwhiti kōrero i ngā wā tino nui. Ka ako koe me pēhea te tautoko a ngā teihana waea, te waea-aunoa, ngā hononga aroturuki, me te hiko tārua i te whakapā tere me te pono ki ngā kaiwhakautu, me te aha hoki i whakamahia ai ēnei pūnaha i roto i ngā puni, i ngā wāhi waka, i ngā wāhi kawe waka, me ētahi atu taiao haumaru.

He aha te Pūnaha Waea Āwhati

He pūnaha waea ohorere he hanganga whakawhitiwhiti kōrero motuhake, he haumaru hoki, i hangaia hei whakarato whakapā tonu, pono hoki ki ngā kaiwhakataki ohorere, ki ngā teihana aroturuki matua rānei. He rerekē ki ngā whatunga whakawhitiwhiti kōrero paerewa, e whakatairanga ana i te nui o te waka me te maha o ngā āhuatanga, he mea hanga ngā pūnaha ohorere kia roa ai te wā mahi, kia kore ai e aukati i ngā aukati PBX ā-rohe me te pupū o te whatunga waea pūkoro.

Ka whakatinanahia ēnei pūnaha ki ngā taiao e tino arohia ana te haumaru o te marea, hei puna ora tika i ngā wā tino kino. Ka mahi motuhake rātou i ngā hanganga ā-kaihoko, ka whakamahi i ngā taputapu pakari me ngā ara whatunga koretake hei whakarite kia hono tonu ngā waeatanga ohorere me te kore e whakaroa, e motuhia rānei.

Ngā wāhanga matua me ngā mahi

Ko te hanganga o tētahi pūnaha waea ohorere e whakawhirinaki ana ki ngā taputapu pakari kua hangaia hei tu atu i ngā ahotea taiao me te whakangaromanga. I te taumata mutunga, ka whakamahia e ngā pūnaha ngā panera kore-ringa,ngā pouaka waea ohorere ātete-huarere, ngā teihana waea motuhake rānei. Kei roto i ēnei pito mutunga ngā waea aunoa ka taea te whakarite hei tīmata i te waea i te wā tonu ka pēhia he pātene, ka hikitia rānei te waea.

He wāhanga nui te kore e taea te whakamahi i te hiko. Me whakauru e ngā pūnaha ohorere paerewa-ahumahi ngā pūhiko hiko kore e taea te motumotu (UPS) me ngā pūhiko tārua ā-rohe e taea ai te tuku hiko tatari mō te iti rawa 24 hāora me te 4 hāora o te wā kōrero tonu i te wā e pakaru ana te whatunga tuatahi. Ko ngā ārai ātete-whakararu, he mea hanga pinepine mai i te maitai kore waikura 14-gauge, 16-gauge rānei, ka tiaki i ngā papa hiko ā-roto mai i te kino tinana me te urunga mai o te makuku.

Te huarahi e tukuna ai ngā waea me te whakarite i ngā kaupapa matua

Ina whakahohehia he pito whakamutunga, ka karohia e te pūnaha te whakawhiti ā-rohe paerewa hei whakarite i te hononga ki waho. Ka tukuna tika ngā waea ki tētahi Pūwāhi Whakautu Haumaru ā-Iwi (PSAP), ki tētahi tēpu haumarutanga o te puni, ki tētahi teihana aroturuki matua tuatoru rānei. Ka whakaurua tēnei ara ki roto i te pito whakamutunga, ki te kuwaha ohorere matua rānei, kia kore ai he hapa a te kaiwhakamahi i te wā e mataku ana.

Ka tukuna e ngā pūnaha waea ohorere matatau ngā raraunga Tautuhi Tau Aunoa (ANI) me te Tautuhi Wāhi Aunoa (ALI) me te kawenga reo. Ka whakakī tonu ēnei mōkihi raraunga i te mata o te kaituku me ngā taunga ā-tinana, te wāhanga hanga rānei o te kaikaea. I roto i ngā taiao whatunga, ka whakawhiwhia e ngā kawa Kounga Ratonga (QoS) te kaupapa matua whatunga ki ēnei mōkihi Reo i runga i te IP (VoIP), ka ārai i te hekenga o te waea ahakoa i te wā e tino kapi ana te whānui o te hononga.

Ngā kōwhiringa hoahoa matua mō ngā kaihoko

Me whakamahi ngā kaihoko e arotake ana i ngā hanganga whakawhitiwhiti kōrero ohorere i ngā momo whatunga matua e toru: te anaro (POTS), te waea pūkoro, me te VoIP/SIP. I ngā wā o mua, ko ngā raina Ratonga Waea Tawhito (POTS) te paerewa nā te mea he mana-whaiaro tō rātou. Heoi, i te mea kua whakakorea e ngā kaiwhakarato waea ngā hanganga parahi, kei te piki haere te heke o ngā kaihoko ki ngā huarahi hou.

Ka whakamahia e ngā kēti waea pūkoro ngā whatunga LTE, 5G rānei, he maha ngā wā ka whakauruhia ki ngā pouara SIM-rua hei tautoko i te kawe. He tino whai hua ēnei mō ngā wāhi tawhiti e nui ana te utu mō te tango taura tinana. I tua atu, ka whakamahia e ngā pūnaha VoIP e hangai ana ki te Session Initiation Protocol (SIP) ngā hanganga LAN/WAN hinonga o nāianei. Mā ngā pito mutunga SIP ka taea te whakahaere pokapū, te whakahou i ngā pūmanawa mamao, me te uiui tonu hei manatoko i te hauora o te taputapu, ā, koinei te kōwhiringa hoahoa pai mō ngā puni umanga nui, whare wānanga rānei.

He aha te Hiranga tonu o ngā Pūnaha Waea Āwhati

Ahakoa te kitea whānuitia o ngā waea pūkoro, he wāhanga nui tonu ngā pūnaha waea ohorere motuhake o te hanganga haumaru ora. Ka ngāwari ngā taputapu pūkoro ki te pau o te pākahiko, te motumotu o te whatunga, me ngā rohe mate pūtau, ā, ka kore e pono i roto i ngā taiao hanganga, taiao whenua rānei.

Mā ngā pūnaha motuhake ka whakaratohia he pūwāhi whakawhitiwhiti kōrero pumau, mōhiotia hoki ka taea e ngā kaiwhakautu ohorere te whakawhirinaki atu. Hei tāpiri, ka tutuki i a rātou ngā ture me ngā ture whakahaere pakari e hiahia ana kia whakaratohia e ngā kaipupuri whenua he hongere whakawhitiwhiti kōrero ohorere e wātea ana, ahakoa te kore e whakamahi i te pūrere whaiaro a te kaiwhakamahi.

Me pēhea te whakaiti i te wā whakautu

Ko te painga matua o tētahi pūnaha waea ohorere pumau ko te whakaiti nui i ngā wā urupare ohorere. Mēnā kei te whakamahi waea pūkoro te kaikaea, me whakapuaki ā-waha e te kaikaea tōna wāhi tuturu—he tukanga ka tino pāngia e ngā hapa i ngā wā taumaha, kāore rānei e taea mēnā kāore te kaikaea e kaha ki te mahi.

Nā te mea ka tukuna tonutia ngā raraunga ALI tika e ngā waea ohorere motuhake i te hononga, kāore e hiahiatia ana e ngā kaiwhakahaere te whakatōpū i tētahi tohu, te pātai rānei i te kaikaea mō ngā tohutohu. E whakaatu ana ngā raraunga ahumahi ka taea e ngā pūnaha ohorere tauwāhi pumau te whakaiti i ngā wā tuku tuatahi mā te 60 ki te 90 hēkona ki te whakataurite ki ngā waea pūkoro 911 paerewa. I roto i ngā āhuatanga ohorere hauora, i ngā āhuatanga riri kaha rānei, ka tino whakapai ake tēnei tere o te whakatinanatanga rauemi i ngā tūponotanga putanga.

Ko te wāhi e tino hira ana rātou

He mea whakahau ngā pūnaha waea ohorere i roto i ngā taiao e kitea ana te mokemoke, te mōrearea nui, te hekenga rānei o te tohu. He maha ngā wā kāore e taea te uru atu ki ngā pūtau i roto i ngā hanganga o raro whenua, i ngā whare kua āraia rawatia, me ngā rohe ahumahi tawhiti.

Ngā Whakaritenga Hangarau, Whakatutukitanga, me te Whakaurunga

Ko te whakatinanatanga o tētahi pūnaha waea ohorere me mātua piri ki tētahi whatunga uaua o ngā ture hanga, ngā paerewa urunga, me ngā whakaritenga hangarau. Ki te kore e tutuki i ēnei whakaritenga, ehara i te mea ka whakararu noa i te haumaru o te kaiwhakamahi, engari ka tūpono hoki ngā kaiwhakahaere whare ki ngā nama ture me ngā nama pūtea nui.

Ngā waehere me ngā paerewa hei whakaaroaro

E whakatakoto ana te Ture mō ngā Hauātanga o Amerika (ADA) i ngā tawhā ā-tinana me ngā tawhā whakahaere mō ngā waea ohorere i te Hononga o Amerika. E ai ki te ADA, me whakahaere ngā taputapu whakawhitiwhiti kōrero me te kore e hopukia, e pēhia, e takahuri rānei te ringaringa, ā, me whakahohe me te kaha mōrahi o te 5 pauna. Hei tāpiri, me whakairi te wāhanga teitei rawa o te waea kia kaua e neke ake i te 48 inihi mai i te papa kua oti hei toro atu ki mua, ki te taha rānei.

Mō te kawe waka poutū, ko te ASME A17.1/CSA B44 Safety Code for Elevators and Escalators te kaiwhakahaere o ngā whakawhitiwhiti kōrero ohorere. Ko ngā whakahoutanga hou o tēnei waehere e whakahau ana me whakauru ngā pūnaha whakawhitiwhiti kōrero ararewa i ngā āheinga ataata rua-ara mō te hunga turi ngoikore, me te manatoko i te whakahaere o ngā raina i ia rā. Hei tāpiri, ko te National Fire Alarm and Signaling Code (NFPA 72) e whakamārama ana i ngā whakaritenga tino pakari mō te oranga tonutanga mō ngā taura me ngā pūtake hiko e tautoko ana i ēnei pūnaha.

Ngā whakaritenga taiao me te wā mahi

Me mahi pai ngā waea ohorere i roto i ngā āhuatanga kino. Ko ngā pito waea e tāutahia ana i waho, i roto rānei i ngā taiao ahumahi, me whiwhi i ngā whakatauranga Parenga Whakauru (IP) teitei. Ko te whakatauranga IP66 te paerewa iti rawa mō ngā pouaka waea o waho, hei whakarite i te tiakitanga mai i ngā ngaru nui, i ngā rerenga wai kaha rānei, ko ngā taputapu kua whakatauranga IP67 ka taea te tu atu i te rukutanga poto.

He mea nui anō hoki te ātete ki te wera. Ko ngā pūnaha waea ohorere kounga teitei he mea hanga ki ngā awhe pāmahana whakahaere roa, e mahi pono ana mai i te -40°C ki te +65°C (-40°F ki te +149°F). Hei whakarite i te wā mahi, ka whakamahia e ngā pūnaha hou e hangai ana ki te SIP te pōti aunoa—e tuku ana i ngā pito whakamutunga i ia 10 ki te 15 meneti. Mēnā kāore he pito whakamutunga e whakautu mai, ka whakaputa tonu te pūnaha i tētahi whakatūpato ki ngā kaiwhakahaere whare, kia tika ai te whakatika i te waeine i mua i te puta mai o tētahi āhuatanga ohorere.

Te whakaurunga ki ngā ararewa me ngā pūnaha haumaru

Kāore i te maha ngā pūnaha waea ohorere hou e mahi takitahi ana; kei te whakaurua haeretia ēnei ki roto i ngā pūnaha whakahaere whare whānui me te haumarutanga ā-tinana. Mā te whakamahi i ngā paerewa tuwhera pēnei i te ONVIF me te SIP, ka taea e tētahi waea ohorere te whakaoho i ngā urupare aunoa puta noa i ngā tūāpapa maha.

Hei tauira, mā te whakahohe i tētahi waea ohorere i roto i tētahi whare waka ka taea te whakahau aunoa i tētahi Pūnaha Whakahaere Ataata (VMS) kua whakauruhia ki te huri, te whakatītaha, me te whakanui (PTZ) i te kāmera tirotiro tata ki te kaikaea. Waihoki, mā te whakaurunga ki ngā pūnaha whakahaere urunga ka taea e ngā kaiwhakahaere teihana matua te iriti i ngā tatau, i ngā kēti rānei mō ngā kaihopu tuatahi mai i te papatohu whakawhitiwhiti kōrero o te waea ohorere, ka māmā ake te tukanga wawao.

Whakatakotoranga, Tāutanga, me te Tiaki

Ko te huringa ora o tētahi pūnaha waea ohorere—mai i te whakatakotoranga tuatahi ki te tiaki tonu—me whai huarahi whakarite kia mau tonu ai te pono. Me whakataurite ngā whakataunga hoko i ngā whakapaunga whakapaipai o mua me ngā utu whakahaere mō te wā roa me te roa o te pūnaha.

Me pēhea te aromatawai i ngā kaihoko

I te wā e whiriwhiri ana i tētahi kaihoko, me arotake e ngā kaihoko te hītori mahi a te kaihanga mō te roa o te mau o ngā taputapu me te tautoko pūmanawa. Ko ngā inenga matua ko te Wā Tohatoha i waenganui i ngā Rahunga (MTBF), arā, mō ngā pito mutunga ohorere kounga teitei me neke atu i te 50,000 hāora. Me whakarato e ngā kaihoko he tuhinga whānui e whakaatu ana i te tutuki i ngā whakaritenga UL,Ngā paerewa CE, me te FCC.

Hei tāpiri atu, me arotake e ngā kaihoko ngā tikanga whakamana a te kaihoko me te SLA tautoko hangarau. Ka tukuna e te kaihanga rongonui he whakamana iti rawa 2-tau ki te 5-tau mō ngā wāhanga taputapu nui, ā, ka whakamanahia te wātea o ngā wāhanga whakakapinga mō te iti rawa tekau tau, e whakaata ana i te huringa ora e tumanakohia ana o te hanganga haumaru-ora.

Ngā kaiārahi utu matua

Ko te utu katoa o te mana whakahaere mō tētahi pūnaha waea ohorere e ārahihia ana e ngā whakatakotoranga taputapu, te hoahoa whatunga, me ngā uauatanga o te tāutanga. Ko ngā pito mutunga taketake o roto, o roto rānei, kei waenganui i te $300 ki te $600 ia waeine. Heoi, ko ngā pito mutunga pakari, IP67-rated, rāneiNgā tauira ātete-pahū kua whakamanahia e ATEXmō ngā taiao morearea ka neke ake i te $1,500 ki te $2,500 ia waeine.

Ko ngā whakarerekētanga hanganga tētahi atu take nui mō te utu. Ko te whakahou i ngā pūnaha anaro tawhito ki te VoIP me tango he taura Ethernet Cat5e/Cat6 hou, me tāuta rānei he keti anaro-ki-IP. Mō ngā tāutanga mamao o waho, ka nui rawa te utu mō te keri i te awa mō te paipa, ā, ka waiho ngā keti waea pūkoro—ahakoa ngā utu raraunga ia marama—hei otinga mō te wā roa, he iti ake te ōhanga.

Ngā tikanga whakamātautau me te tiaki

He tino rahunga mahi te whakawhirinaki noa ki ngā pūnaha ohorere; he mea whakahau te whakamātautau pakari, kua whakaritea. I ngā wā o mua, me hikoi ā-tinana ngā kaimahi tiaki ki ia pito, pēhi i te pātene, me te manatoko i te hononga. I ēnei rā, ka aunoatia tēnei tukanga e ngā pūnaha atamai.

Hei tauira, e hiahiatia ana e te ASME A17.1 kia manatoko aunoa ngā waea ohorere o te ararewa i te pono o te raina whakawhitiwhiti kōrero i te iti rawa i te kotahi i roto i ngā haora 24. Mēnā ka rahua te raina, me whakaoho e te pūnaha he whakaoho oro me te whakaoho tirohanga ā-rohe. Haunga ngā tirotiro raina aunoa, me whakahaere e ngā kaiwhakahaere whare he whakamātautau ā-ringa whānui ia toru marama, me te manatoko i te mārama o te hopuoro, te oro o te kaikorero, te mahi o te hihi, me te tika o ngā raraunga ALI kua tukuna ki te PSAP.

Me pēhea te whiriwhiri i te pūnaha waea ohorere tika

Mā te whakataurite i te pūnaha waea ohorere tika ki tētahi taiao mahi motuhake ka whakarite kia tutukihia ngā ture, me te arotau hoki i ngā haumitanga hanganga. Ko te tukanga whakatau e whakawhirinaki ana ki te aromatawai i ngā āheinga whatunga o nāianei, ngā tūponotanga taiao, me ngā hiahia whakawhitiwhiti kōrero motuhake o ngā kaiwhakamahi mutunga.

Ngā pūnaha tūkotahi me ngā pūnaha whakauru

Ka mahi motuhake ngā pūnaha motuhake i te whatunga hinonga, mā te whakamahi i ngā raina anaro motuhake, i ngā hononga pūkoro motuhake rānei. He tino ātete ēnei ki ngā motuhanga whatunga ā-rohe, ki ngā whakaeke ipurangi rānei, nā te mea kāore e tohaina ngā hanganga me ngā raraunga hangarau mōhiohio paerewa. He pai mō ngā wāhi motuhake, mō ngā whare rānei kua tawhito ngā whatunga hangarau mōhiohio.

Mā ngā pūnaha whatunga whakauru, mā te whakamahi i te SIP/VoIP, ka whakakotahi i ngā whakawhitiwhitinga ohorere ki te LAN/WAN a te kamupene. Mā tēnei huarahi ka whakaitihia ngā utu raina whakawhitiwhiti kōrero auau, ā, ka taea te whakahaere pokapū mā te papaaho kotahi. Ka tautokohia e ngā pūnaha whakauru ngā āhuatanga matatau pērā i te pāpāho papatipu, ka taea te whakahohe i ngā kaikorero waea ohorere katoa i te wā kotahi hei tukungā pānuitanga whaikōrero tūmatanuii te wā o te raruraru puta noa i te kāmpus. Heoi, me kaha te whakamahi i ngā whatunga hou, tae atu ki ngā pana PoE (Power over Ethernet) e tautokona ana e te UPS, kia ora ai i te wā e pakaru ana te hiko.

Ngā paearu whiriwhiri mā te whakamahinga

Ko te whiriwhiri i te pūnaha tino pai me whai tātaritanga taipitopito mō ngā whakamahinga katoa. Me whakarite e ngā kaihoko tō rātou taiao ā-tinana ki te hangarau e tika ana.

Mā te arotake pūnaha i ēnei paearu—mai i te hanganga ture ADA me ngā whakatauranga MTBF ki te āhua whatunga me ngā āheinga whakauru—ka taea e ngā kaiwhakahaere whare te hoko i tētahi pūnaha waea ohorere e whakarato ana i tētahi ara ora pumau, haumaru hoki ina tino hiahiatia.

Ngā Whakaaro Matua

• Ngā whakatau me ngā take matua mō te Pūnaha Waea Āwhati
• Ngā whakaritenga, ngā whakaritenga, me ngā arowhai mōrearea e tika ana kia whakamanahia i mua i tō whakaae
• Ngā mahi whai muri me ngā whakatūpato ka taea e ngā kaipānui te tono tonu

Ngā Pātai Auau

He aha te pūnaha waea ohorere?

He pūnaha whakawhitiwhiti kōrero motuhake tēnei e hono tika ana i ngā kaiwhakamahi ki te haumarutanga, ki te ratonga tuku, ki tētahi pokapū aroturuki rānei, me te iti rawa o te whakaroa, ahakoa he pupūnga whatunga, he raruraru hiko rānei.
