Momwe Mungakhazikitsire Dongosolo Losalowa Madzi la PA Speaker la Kulankhulana Mwadzidzidzi

Bukuli likufotokoza momwe mungasankhire, kuyika, ndikutsimikizira cholankhulira chosalowa madzi kuti mulankhule mwangozi modalirika. Likuwonetsanso momwe mungafananizire njira zakunja za PA, zosowa zotulutsira mawu, ndi njira zosankhira ogulitsa popanda kusakaniza magulu azinthu.

Chifukwa chake cholankhulira mawu chosalowa madzi chili chofunikira pakupanga makina olankhulira mwadzidzidzi

Cholankhulira mawu chosalowa madzi ndi chinthu chodalirika, osati chowonjezera mawu okha. Mu makina olankhulira adzidzidzi, chiyenera kupulumuka mvula, fumbi, kugwedezeka, kupopera mchere, ndi kusintha kwa kutentha pamene chikuperekabe malangizo omveka bwino. Kulankhulana mwadzidzidzi kumadalira kumveka bwino komanso kumveka bwino, makamaka pamene ma alamu ayenera kuletsa mauthenga achizolowezi. OSHA imanena kuti makina olankhulira antchito angagwiritse ntchito makina olankhulira anthu onse, ma wailesi, kapena mafoni popereka malipoti adzidzidzi, ndipo mauthenga adzidzidzi ayenera kukhala patsogolo kuposa magalimoto osafunikira mwadzidzidzi. Pakuchotsa mawu ndi kudziwitsa anthu ambiri, NFPA 72 Chapter 24 imagwiritsa ntchito makina olankhulirana mawu kapena ma adilesi a anthu onse ngati gawo la kapangidwe ka makina olankhulirana mwadzidzidzi. Izi zikutanthauza kuti cholankhulira ndi gawo la magwiridwe antchito otetezeka, osati chipangizo chodziyimira pawokha cholankhulira.

Momwe mungadziwire mawu okweza osalowa madzi oyenera kukhazikitsa makina a PA

Kukhazikitsa bwino kwa makina a PA kumayamba ndi chilengedwe, osati kabukhu. Cholankhulira cha malo onyamulira katundu, khomo lolowera mu ngalande, kapena bwalo la mankhwala chimafuna chitetezo chosiyana ndi kutulutsa mawu kuposa chomwe chimagwiritsidwa ntchito mu khonde lotetezedwa. Gwiritsani ntchito njira zotsatirazi musanayerekezere mitundu:

• Gawo 1: Fotokozani kuchuluka kwa ngozi ndi momwe zinthu zilili, kuphatikizapo mvula, kusamba, fumbi, dzimbiri, ndi ngozi ya kuwonongeka.
• Gawo 2: Tsimikizani khodi ya IP yofunikira pansi pa IEC 60529, kenako igwirizane ndi malo enieni oikira. Buku la IP la IEC limafotokoza kuti khodiyi imagawa chitetezo ku zinthu zolimba ndi kulowa kwa madzi.
  
• Gawo 3: Tsimikizirani zosowa za mawu, kuphatikizapo mtunda wofikira, phokoso la malo ozungulira, ndi kumveka bwino kwa mawu.
• Gawo 4: Onetsetsani ngati dongosololi likulemba page nthawi zonse, kudziwitsa zadzidzidzi, kapena kutulutsa mawu.
• Gawo 5: Tsimikizirani kuyika, kulowa kwa chingwe, mwayi wokonza, ndi kupezeka kwa zida zina.

Mu mapulojekiti ambiri, yankho lolondola si gawo lotulutsa zinthu zambiri. Ndi gawo lomwe limapereka mawu okwanira omveka bwino pamalo ofunikira kwambiri, ndi ntchito yochepa yokonza.Tebulo Loyerekeza: Magulu a Sipikala Yakunja a Kulankhulana Mwadzidzidzi

Kwa mabanja azinthu, tsamba lawebusayiti lomwe likufunidwa limakonza njira zothetsera mavuto m'machitidwe olumikizirana m'mafakitale, mafoni osaphulika komanso otetezeka mwachibadwa, mafoni osawonongeka komanso osawonongeka, mafoni olumikizirana mwadzidzidzi ndi mafoni, komanso makina olankhulirana pagulu. Magulu amenewo amathandiza ogula kugwirizanitsa okamba ndi ma netiweki ena onse olumikizirana.

Ndi miyezo iti yomwe iyenera kutsogolera makina olankhulira pa nthawi yadzidzidzi

Dongosolo la okamba nkhani zadzidzidzi liyenera kusankhidwa motsatira miyezo, osati malingaliro. Mafotokozedwe ofunikira kwambiri ndi zofunikira za alamu ya ogwira ntchito ku OSHA, NFPA 72 yolumikizirana zadzidzidzi, IEC 60529 yoteteza kulowa kwa mawu, ndi ATEX yokhudza mlengalenga wophulika. ATEX ndi yofunika kwambiri pamene kukhazikitsa kuli mumlengalenga wophulika. European Commission ikufotokoza kuti Directive 2014/34/EU imakhudza zida zomwe zimagwiritsidwa ntchito mumlengalenga wophulika, pomwe malangizo a kuntchito amakhudza maudindo a olemba ntchito. Pazokhazikitsa panja kapena m'mafakitale, mfundo yothandiza ndi yosavuta: kuwerengera kwa enclosure kuyenera kufanana ndi chilengedwe, ndipo kapangidwe ka mawu kuyenera kufanana ndi momwe amagwiritsidwira ntchito mwadzidzidzi. Wokamba nkhani amene amapulumuka nyengo koma sangathe kupereka mawu omveka bwino akadali kapangidwe kofooka.Tebulo Loyerekeza: Miyezo ndi Tanthauzo Lake pa Kukhazikitsa kwa PA System

Momwe mungayerekezere njira zakunja za PA popanda kutchula mopitirira muyeso

Dongosolo la PA lakunja liyenera kukulitsidwa malinga ndi momwe zinthu zilili, osati malinga ndi zomwe anthu amaganizira. Zosintha zazikulu ndi phokoso lozungulira, kutalika kwa malo oikira, komwe kuwala kumalowera, ndi kuchuluka kwa madera omwe amafunika kulamulira pawokha. Pochita izi, magulu a polojekiti ayenera kuyerekeza magawo atatu a magwiridwe antchito. Choyamba, malo ozungulira ayenera kukana malo omwe ali. Chachiwiri, mawonekedwe a mawu ayenera kuphimba malo omwe akufunidwa. Chachitatu, dongosololi liyenera kugwirizana ndi nsanja yowongolera, kaya ndi analog paging, IP audio, kapena njira yayikulu yotulutsira mawu mwadzidzidzi. Malangizo ochokera ku Honeywell pa kutulutsa mawu akugogomezera kumveka bwino komanso kapangidwe kake komwe kumakhudza magwiridwe antchito a mawu m'malo opezeka anthu ambiri. Izi ndizothandiza chifukwa mauthenga adzidzidzi amalephera anthu akamva mawu koma sangamvetse mawu.
