Kuki telefoni ikoresha itumanaho rijyanye n'umutekano w'ubucukuzi bw'amabuye y'agaciro idashobora gukoresha telefoni isanzwe yo mu biro?

• Terefone zo mu biro zubatswe kugira ngo zigenzurwe mu nzu, mu gihe telefoni zanjye zubatswe kugira ngo zikoreshwe mu ivumbi, impanuka, ubushuhe n'akazi kihutirwa.
• Itumanaho ryo mu muhanda rigomba gushyira imbere ubushobozi bwo kubaho, gusobanukirwa, no kugera ku buryo bwihuse, atari ubuziranenge bw'amajwi gusa.
• Amabwiriza akurikizwa hamwe n'ishyirwa mu byiciro ry'ibyago ni byo bigena niba igikoresho gishobora gukoreshwa mu gace k'ubucukuzi bw'amabuye y'agaciro.
• Imiterere ya sisitemu ni ingenzi kimwe n'iy'iterefone: gukoresha insinga, kubika umuriro, gushyiramo no guhuza n'ingufu zose bigira ingaruka ku mutekano.
• Ku matsinda ashinzwe gutanga amasoko, ikibazo gikwiye si “Ese ishobora guhamagara?” ahubwo ni “Ese izakomeza gukora igihe ibintu bizaba bibi?”

Terefone ikoresha itumanaho rijyanye n'umutekano mu bucukuzi bw'amabuye y'agaciro ni igikoresho cyihariye gikoreshwa mu nganda, si telefoni yo mu biro yahinduwe, kuko itumanaho ryo munsi y'ubutaka rigomba gukomeza kuba ingirakamaro mu bihe bishobora kuba birimo methane, umukungugu w'amakara, amazi yinjira, kunyeganyega, n'urusaku rwinshi rw'imashini. Mu kirere cy'akaga, guhitamo ibikoresho bigengwa n'amahame nkaIECno mu mategeko y’umutekano yihariye ku bucukuzi bw’amabuye y’agaciro; urugero, ibitekerezo byo kurinda ibisasu munsi yaIECExbyubatswe ku buryo bwo kwirinda ko isoko y'umuriro iba akaga. Ku bijyanye n'amajwi n'uburyo bwo gukoresha, telefoni isanzwe yo mu biro nayo ni ingenzi cyane ku buryo itabasha kugera ku bintu aho kuganira neza bishobora kugorana kurusha gushyikirana neza. Niba akazi ari ingenzi ku mutekano, itumanaho rigomba kumera nk'ibikorwa remezo by'inganda kuruta ibikoresho by'ikoranabuhanga bikoreshwa n'abaguzi.

Impamvu terefone y'itumanaho ikoresha umutekano w'ubucukuzi bw'amabuye y'agaciro ikenera ibirenze ibiranga ibiro

Itandukaniro rya mbere ni imikorere: sisitemu ya telefoni ya mine yubatswe kugira ngo umutekano ukomeze, mu gihe telefoni yo mu biro yubatswe kugira ngo yorohereze.

Terefone zo mu biro zifata ingufu zihamye, urusaku ruke, nta kibazo cyo kuziba ivumbi, ndetse n'ubushyuhe buke. Itumanaho ryo munsi y'ubutaka ntirikora. Ikirombe gishobora gusaba telefoni ishobora kwihanganira gutungurwa, gusukurwa, ivumbi ritwara amashanyarazi, gucurangwa n'insinga ndende, no gukoreshwa kenshi wambaye uturindantoki. Mu bihe byihutirwa, umukoresha ashobora kugira stress, kwambara ubwirinzi bwo kumva, cyangwa guhagarara ahantu hari urusaku aho mikoro n'indangururamajwi bisanzwe byo mu ntoki bidahagije.

Itandukaniro rya kabiri ni uko urwego rw'ibyago rushyirwa mu byiciro. Niba ikirombe gifite metani cyangwa ivumbi rishobora gushya, igikoresho cy'itumanaho kigomba gutoranywa nk'igice cy'imiterere y'umutekano w'agace, ntabwo ari nk'aho gikoreshwa mu buryo busanzwe mu bijyanye n'ikoranabuhanga. Niyo mpamvu telefoni z'inganda zikunze guhuzwa n'ibiziriko, inzitizi zemewe, cyangwa amategeko agenga aho ibintu bishyirwa aho ibintu bikorohera aho gukoresha ibikoresho byoroshye. Kugira ngo hamenyekane amakuru ajyanye n'ikirere giteje akaga n'amahame yo kurinda ibisasu, Ishyirahamwe ry'Igihugu Rishinzwe Kurinda Inkongi rya Amerika ritanga ubuyobozi rusange binyuze mu bikoresho byaryo by'umutekano, kandi Ikigo gishinzwe umutekano n'ubuzima mu birombe bya Amerika gisohora inyandiko zijyanye n'umutekano mu birombe kuMSHA.

Itandukaniro rya gatatu ni uburyo bwo kuboneka. Mu biro, guhagarara by'agateganyo ni ikibazo. Mu kirombe, ikibazo cy'itumanaho gishobora gutinza gusohoka, kugabanya aho gukorera, cyangwa gutinda gusubiza ibintu mu buryo. Niyo mpamvu imishinga myinshi isuzuma sisitemu yose, atari telefoni gusa. Iyo ugereranya imiryango y'ibicuruzwa, bifasha gusuzuma amahitamo y'inganda nkatelefoni y'inganda, telefoni irinda ikirere, natelefoni idaturikambere yo gufata icyemezo niba aho hantu hakenewe ibikoresho by'itumanaho bikomeye, bifunze, cyangwa bishobora guteza akaga.

Ibisabwa kuri sisitemu ya telefoni mu itumanaho ryo munsi y'ubutaka

Igisabwa cy'ingenzi kuri sisitemu ya telefoni yo mu kirombe ni uburyo bwo gukoresha ijwi mu gihe hari ikibazo, ntabwo ari ubwiza bw'amajwi atangwa n'abaguzi.

Mu itumanaho ryo mu bwihisho, kumva neza kw'amagambo ni ingenzi kuruta uburyo amajwi akoreshwa mu buryo bwemewe. Ibirombe bikunze kuba binini, bivuza ijwi, kandi bifite imipaka. Urusaku rw'imashini rukunze kurenga 85 dBA mu nganda, ari na rwo rugero rumwe rukoreshwa n'amategeko agenga kubungabunga amatwi mu kazi mu turere twinshi. Ikigo gishinzwe umutekano n'ubuzima mu kazi cya Amerika gishyiraho impuzandengo y'amasaha 8 ya 90 dBA ku nganda rusange, kandi Ikigo cy'Igihugu gishinzwe umutekano n'ubuzima mu kazi gitanga inama ya 85 dBA nk'urwego rwo kwirinda cyane. Iyo mibare si imiterere ya telefoni, ariko isobanura impamvu igikoresho cy'itumanaho cyo mu birombe kigomba gutanga ijwi ryumvikana, gufata mikoro neza, no gukora neza kurusha telefoni isanzwe yo mu biro. RebaUbuyobozi bw'urusaku bwa OSHAnaInkomoko y'urusaku rwa NIOSH.

Ubukana ni ikindi kintu gisabwa. Igikoresho gikoreshwa ku muyoboro w'ikirombe, mu cyumba cyo kugenzura, ku murongo w'itumanaho, cyangwa ahantu hahungirwa munsi y'ubutaka gishobora kugira ingaruka mbi, ivumbi rikwirakwira, ndetse no guhumeka. Ibipimo byo kurinda inganda nka IP66 cyangwa IP67 bikunze gukoreshwa mu gusobanura uburyo bwo kwirinda kwinjira.ISO 20653:2013, amanota menshi ya IP agaragaza ko hari uburinzi bukomeye ku mukungugu n'amazi yinjira, ari nayo mpamvu imwe mu mpamvu telefoni zo mu nganda zishyirwamo ibikoresho bifunze kandi birwanya ingese aho kuba ibikoresho bya pulasitiki bikoreshwa.

Gukoresha byihutirwa nabyo ni ingenzi. Mu gihe cy'ibibazo, uburyo bwo gukoresha interineti bugomba kuba bugaragara: guhamagara rimwe gusa, utubuto tunini, kwemeza amajwi, no kwerekana aho ibintu biherereye neza. Telefoni isanzwe yo mu biro ishobora kuba ifite utubuto twinshi tworoshye, menu, n'ibintu bishingiye kuri interineti bigira akamaro mu cyumba cy'icumbi ariko ntibigire icyo bitanga iyo umukozi akeneye kuvugana n'abakozi bo mu cyumba cy'ubuyobozi. Niyo mpamvu itsinda rishinzwe gutanga amasoko akenshi rikunda ahantu ho gukorera ibikoresho byubatswe mu nganda ahantu hadahinduka hanyuma rikahubaka izindi sisitemu zikikije.

Ingaruka zo guturika, ivumbi, n'impamvu telefoni zisanzwe zo ku meza ari ikibazo cy'umutekano

Impamvu ikomeye ituma telefoni isanzwe yo mu biro idakwiye ni uko ibikoresho byayo by'ikoranabuhanga, ububiko, n'ibindi bikoresho bitagenewe kwirinda ibyago byo gushya mu kirere cy'ibirombe.

Mu birombe byinshi, ikibazo si ukumenya niba igikoresho gishobora kurokoka ikizamini cyo gushoka; ahubwo ni ukumenya niba igikoresho gishobora gukoreshwa hatabayeho isoko y'umuriro. Niyo mpamvu hari amahame agenga uburinzi bw'ibisasu kandi impamvu icyemezo ari ingenzi. Telefoni isanzwe, umuriro w'amashanyarazi, cyangwa modular connector bishobora kwemerwa mu cyumba cy'inama ariko ntibikwiye kwemerwa aho gaze ishobora gushya cyangwa ivumbi rishobora gushya rishobora kuba riri. Mu by'ukuri, ndetse n'utundi duto nka contacts zigaragara, arcing y'imbere, no gutanga ubushyuhe bigomba kwitabwaho.

Ku bikoresho byo mu gace gashobora guteza akaga, urwego rubikwiye rushingiye ku gushyira mu byiciro ikirere n'igitekerezo cyo kurinda. Uburyo bwo kurinda ahantu hashobora gutera akaga bwa IEC ntibushobora guhindurwa, kandi igikoresho cyemewe n'akarere kamwe cyangwa itsinda rya gazi ntigishobora gukora ku kandi. Bityo, abaguzi bagomba guhuza urwego rw'aho hantu n'icyemezo, atari ibisobanuro by'ibicuruzwa gusa. Ibi ni ingenzi cyane mu itumanaho rya mine kuko umurongo umwe wa terefone ushobora kunyura mu bice byinshi byo kugaragaramo, harimo aho kwinjira, amatara, sitasiyo nto, n'ibyumba byo kugenzura.

Umukungugu nawo ni ingenzi. Umukungugu muto ushobora kwinjira mu byuma bihindura amajwi, mikoro, n'imirongo igabanya ubuziranenge uko igihe kigenda. Ushobora kandi kwirunda ku buso, bigatuma isuku igorana kandi bikongera umutwaro wo kubungabunga. Telefoni nyayo ikoresha utubuto dufunze, ibikoresho birwanya ingese, n'igishushanyo mbonera cy'aho ikorera gishyigikira serivisi ndende. Iyo ni imwe mu mpamvu abaguzi b'inganda bakunze kugereranya telefoni igendanwa gusa, ndetse n'aho icumbika, uburyo bwo kuyishyiraho, n'uburyo bwo kuyikoresha.

Uburyo Itumanaho ryo mu Gicuku ritandukanye n'itumanaho risanzwe ryo mu kazi

Itumanaho ryo munsi y'ubutaka ni igikoresho cy'umutekano mu mikorere, ntabwo ari uburyo bwo korohereza abantu.

Mu biro, guhamagara bitarakorwa birababaza. Mu kirombe, kubura aho bahurira mu gihe cyo gutegura guturika, gutanga akazi, ikibazo cy'ibikoresho, cyangwa kwimura abakozi bishobora kugira ingaruka ku mikorere y'abakozi no ku muvuduko w'ubutabazi. Niyo mpamvu imiterere myinshi ya sisitemu ya telefoni ihuzwa n'ibyumba byo kugenzura, insinga z'amajwi, sisitemu zo kuvugira abantu bose, cyangwa inzira zo kohereza ubutumwa. Aho itumanaho rikorera haba igice cy'uruhererekane rw'ibikorwa.

Uburyo ibimenyetso bikoreshwa n'imbaraga zihoraho nabyo biratandukanye. Gushyiramo ibikoresho munsi y'ubutaka bishobora gushingira ku gukoresha insinga ndende, imiyoboro irinzwe, ingufu zo gusimbuza, no gutandukanya neza n'amasoko y'amashanyarazi asakuza. Niba sisitemu irimo VoIP, imiterere y'umuyoboro igomba kuba ishingiye ku buryo umuyoboro udashobora guhindagurika, imbaraga zikoreshwa kuri Ethernet, n'imyitwarire y'igikoresho mu gihe umuyoboro udafite umurongo. Niba sisitemu ari analog, insinga n'ibiro bikuru biracyakeneye kurindwa ubushuhe, kugabanuka no kwangirika kw'umubiri. Uko biri kose, intego y'igishushanyo ni imwe: gukomeza itumanaho munsi y'ubutaka iyo ahantu hari ikibazo.

Imitekerereze yo kubungabunga ibintu nayo irahinduka. Ibikoresho byo mu biro bikunze gusimbuzwa mu gihe cyo kuvugurura ibintu. Ibikoresho by'itumanaho mu bucukuzi bw'amabuye y'agaciro akenshi bitoranywa kugira ngo bikomeze kubungabungwa, atari mu buryo bw'imyambarire. Amakipe ashinzwe gutanga amasoko arashaka kubona serivisi, kuboneka kw'ibice by'ibicuruzwa, gutanga ibikoresho mu buryo buhamye, no kwandika neza. Aha niho amasoko y'inganda ahabwa agaciro kurusha igiciro gusa. Terefone yo mu biro ihendutse ishobora guhenda iyo inaniwe kenshi cyangwa idashobora kubungabungwa mu buryo busanzwe.

Niba umushinga wawe ukeneye kandi iherezo ry'inganda rijyanye, ni byiza kugereranya imiryango y'ibicuruzwa nkatelefoni yo muri gerezaku byerekeye ibisabwa mu kurwanya kwangiza notelefoni yihutirwakugira ngo habeho guhamagara vuba. Ingingo y'ingenzi ni uko ibidukikije bitandukanye bisaba ko imiterere y'ibintu ishyirwa imbere itandukanye, kabone n'iyo imikorere isa.

Ibipimo ngenderwaho byo guhitamo telefoni ijyanye n'umutekano w'ubucukuzi bw'amabuye y'agaciro

Ibipimo byo guhitamo neza akenshi ni ingirakamaro kurusha uko udutabo twa tekiniki tubigaragaza.

Tangira ukoresheje icyiciro cy'ibyago. Niba imiterere y'agace isaba uburinzi bw'ibisasu, icyemezo ni cyo kiza mbere. Hanyuma urebe uburyo bwo kwirinda kwinjira, uburyo bwo gushyiraho, ubushyuhe, imikorere y'amajwi, n'uburyo serivisi zigerwaho. Ku bice byo hanze cyangwa ku muyoboro, uburinzi bw'ikirere bushobora kuba ingenzi kimwe n'uko ahantu hashobora guteza akaga hashobora kuba ingenzi. Ku biro byo munsi y'ubutaka, uburinzi bw'imitingito n'amajwi bishobora kuba ingenzi kuruta ubwiza.

Hanyuma, suzuma uko ikoreshwa. Icyumba cy’ubuyobozi gikeneye igikoresho gitandukanye n’aho umuntu ahungira munsi y’ubutaka, aho umuntu yimurira imodoka, cyangwa aho akorera ibikorwa byo kubungabunga. Umuryango w’igikoresho kimwe ushobora gukorera ahantu henshi, ariko ibisabwa ntibigomba kuba bimwe. Urugero, aho umuntu ahamagara byihutirwa hashobora gukenera gukoresha akabuto kamwe, mu gihe telefoni yohereza ishobora gukenera inkunga y’amajwi, guhamagara cyane, no gushyira imbere ibyo umuntu ahamagara.

Hanyuma, suzuma ibintu bifitanye isano n’ubuzima bw’ibikoresho. Abaguzi b’inganda bagomba kubaza ibijyanye n’ibikoresho bisimbura ibindi, inkunga yo kubishyiraho, uburyo bwo kwinjira mu nsinga, n’uburyo bwo gutanga icyemezo. Mu bikorwa byo gucukura ahantu henshi, gushyira ibikoresho mu buryo busanzwe ku bwoko buto bw’ibikoresho bigabanya imbaraga zo guhugura no gusimbuza ibintu. Iyo ni imwe mu mpamvu imishinga myinshi ikunda gushakisha ibikoresho bishingiye kuri platform aho gusimbuza abaguzi rimwe gusa.

Ibibazo byo Kugura Ibicuruzwa mu Isi Nyayo Abaguzi Bakwiye Kubaza

Ibibazo byiza byo gutanga amasoko ni ibijyanye n'uburyo bwo gutsindwa, ntabwo ari imiterere y'udutabo.

1. Ese igikoresho kizakomeza kugira umutekano mu kirere cy’ibirombe byagaragajwe?
2. Ese ishobora kuvugana neza iyo urusaku rw'inyuma ruri hejuru ya 85 dBA?
3. Ese inzu ifunze neza ku ivumbi n'amazi byinjira ku rugero rusabwa?
