Ndi chitukuko chosalekeza chamakampani ogulitsa, mtengo wotseguka komanso chidziwitso chaulere chakhala njira yogulitsira yomwe anthu amakonda.Komabe, ngakhale amalonda amapatsa makasitomala mwayi wogula izi, chitetezo chazinthu ndi nkhani yofunika yomwe imasokoneza amalonda.Chifukwa cha malo ogulitsa ndi otseguka, kutayika kwa katundu sikungapeweke.Makamaka, zinthu zina zazing'ono ndi zoyengedwa nthawi zambiri sizikhala zamtengo wapatali.

Tikakumana ndi vuto laminga limeneli, tiyenera kulisamalira ndi kulisamalira moyenera.Ngati sichikugwiridwa, chidzakhudza mwachindunji kupulumuka kwa sitolo.Kodi zimamveka mokokomeza pang'ono?Ndipotu sikukokomeza.Pa chinthu chimodzi, muyenera kugulitsa atatu kapena kupitilira apo kuti mubwezere zomwe zatayika.

Kuti athane ndi vutoli, chinthu choyamba chomwe amalonda amaganizira nthawi zambiri ndikuyika zowunikira, koma kuyang'anira ndi chida chokha chopezera mavuto pambuyo pake, ndipo sichingasinthidwe munthawi yake.Chifukwa pambuyo pa zonse, palibe mphamvu zambiri komanso mphamvu zongoyang'ana nthawi zonse pazenera kuti muwone kasitomala yemwe ali ndi vuto.Ikhoza kufufuzidwa pambuyo pake, koma katundu watayika panthawiyi.

Yankho lapano ndikuyika makina ozindikira zamagetsi a EAS product.Izi zimatengera nthawi.Ngati chinthu chilichonse chosakhazikika chikudutsa panjira yodziwira zitseko, zitha kuchenjezedwa munthawi yake kuti zikumbutse wogulitsa sitolo.

Pakali pano, pali makamaka mitundu iwiri ya zitseko zotsutsana ndi kuba zomwe zimagwiritsidwa ntchito kwambiri pamsika.Imodzi ndi ma frequency 8.2Mhz (omwe amadziwika kuti RF SYSTEM), ndipo inayo ndi 58khz (AM SYSTEM).Ndiye ndi ma frequency ati abwinoko?Kodi kusankha?

1. Pamlingo waukadaulo, zipata zambiri za RF pakadali pano zimagwiritsa ntchito ma siginecha otsanzira, pomwe zipata za AM zimagwiritsa ntchito ukadaulo wa digito.Chifukwa chake, zipata za AM ndizolondola kwambiri pakuzindikiritsa ma siginecha, ndipo zida sizingasokonezedwe ndi ma sign ena osagwirizana.Kukhazikika kwa zida ndizabwinoko.

2. Dziwani m'lifupi mwa njira, kukonzanso kogwira mtima kwa chitseko cha RF ndi chizindikiro chofewa 90cm-120cm cholimba 120-200cm, AM khomo lozindikira nthawi yofewa label 110-180cm, cholemba cholimba 140-280cm, kunena kwake, AM. kuzindikira kwa chitseko Kalekale kakhale kokulirapo, ndipo kuyika kwa malo ogulitsira kumamveka mokulirapo.

3. Mitundu ya osamalira osamalira.Chifukwa cha kagwiridwe kake ka RF, ma tag a RF amasokonezedwa mosavuta ndikutetezedwa ndi thupi la munthu, zojambula za malata, zitsulo ndi ma siginecha ena, zomwe zimapangitsa kulephera kukonza zinthu zamtunduwu.Kunena zoona, zipangizozi ndi zabwino kwambiri, ngakhale pa zinthu zopangidwa ndi malata ndi zinthu zina, zingathandizenso kupewa kuba.

4. Pankhani ya mtengo, chifukwa cha kugwiritsa ntchito zida za RF koyambirira, mtengo wake ndi wotsika kuposa wa zida za AM.Komabe, ndi kuwongolera kosalekeza ndi chitukuko chofulumira cha zida za AM m'zaka zaposachedwa, mtengo watsika pang'onopang'ono, ndipo kusiyana kwamitengo pakati pa zida ziwirizi kukucheperachepera.

5.Kuwoneka kowonetsa zotsatira ndi zinthu.Chifukwa cha zovuta zina za zida za RF, pali opanga ocheperako omwe amaika ndalama pakufufuza ndi chitukuko cha zida za RF.Zida za RF zili ndi malo ochepa opangira chitukuko kuposa zida za AM potengera luso lazopangapanga kapena kafukufuku ndi chitukuko.
