Chithunzi chochititsa chidwi cha mbiri yakale yamaloboti

Magetsi apamsewuzakhala gawo lofunikira pa moyo wathu watsiku ndi tsiku, koma kodi munayamba mwadzifunsapo za mbiri yawo yosangalatsa? Kuyambira pa chiyambi chochepa kufika pa mapangidwe apamwamba amakono, magetsi apamsewu afika patali. Lowani nafe pamene tikuyamba ulendo wosangalatsa wokhudza chiyambi ndi kusintha kwa zida zofunika kwambiri zowongolera magalimoto.

Chidziwitso cha traffic light

Nthawi zambiri magetsi amapangidwa ndi magetsi ofiira (osonyeza kuletsa kuyenda), magetsi obiriwira (osonyeza chilolezo chodutsa), ndi magetsi achikasu (owonetsa chenjezo). Malingana ndi mawonekedwe ake ndi cholinga chake, amagawidwa kukhala magetsi owonetsera magalimoto, magetsi osayendetsa galimoto, magetsi odutsa pamsewu, magetsi owonetsera njira, magetsi owonetserako, magetsi ochenjeza, misewu ndi njanji yodutsa chizindikiro, etc.

1. Chiyambi chodzichepetsa

Lingaliro la kayendetsedwe ka magalimoto linayamba kale ku chitukuko chakale. Kale ku Roma, akuluakulu ankhondo ankagwiritsa ntchito manja poyendetsa magaleta okokedwa ndi akavalo. Komabe, kunalibe mpaka kumapeto kwa zaka za m’ma 1800 pamene magetsi oyendera magetsi oyamba padziko lonse anatulukira. Chipangizochi chinapangidwa ndi wapolisi wa ku United States a Lester Wire ndipo anachiyika ku Cleveland, Ohio mu 1914. Chimakhala ndi mawonekedwe a magetsi apamsewu komanso chizindikiro cha "STOP" chogwiritsidwa ntchito pamanja. Dongosololi lathandizira kwambiri chitetezo chamsewu, zomwe zapangitsa kuti mizinda ina itengerenso mapangidwe ofanana.

2. Mbandakucha wa zizindikiro zodziwikiratu

Magalimoto atayamba kufala, mainjiniya anazindikira kufunika kokhala ndi njira zowongolera magalimoto. Mu 1920, wapolisi wa ku Detroit, William Potts, anapanga magetsi oyambirira amitundu itatu. Kusintha kumeneku kumachepetsa chisokonezo cha oyendetsa mwa kuyambitsa amber ngati chizindikiro chochenjeza. Magetsi odzidzimutsa okha poyamba anali ndi mabelu ochenjeza oyenda pansi. Komabe, pofika m’chaka cha 1930, dongosolo la mitundu itatu limene tikulidziŵa lerolino (lomwe lili ndi magetsi ofiira, achikasu, ndi obiriŵira) linali lofanana ndi kukhazikitsidwa m’mizinda yambiri padziko lonse lapansi. Magetsi apamsewuwa amakhala zizindikiro zowoneka bwino, zowongolera magalimoto ndi oyenda pansi mosavutikira.

3. Kupita patsogolo kwamakono ndi zatsopano

Magetsi apamsewu awona kupita patsogolo kwakukulu m'zaka zaposachedwa, kuwongolera chitetezo komanso kuyenda kwa magalimoto. Magetsi amakono a magalimoto ali ndi masensa omwe amazindikira kukhalapo kwa magalimoto, zomwe zimathandiza kuti pakhale kayendetsedwe kabwino ka mphambano. Kuwonjezera apo, mizinda ina yakhazikitsa magetsi oyendera magalimoto, kuchepetsa kuchulukana komanso kuchepetsa nthawi yoyenda. Kuphatikiza apo, magetsi ena apamsewu ali ndi ukadaulo wa LED, womwe umapangitsa kuti anthu aziwoneka bwino, amapulumutsa mphamvu, komanso amachepetsa mtengo wokonza. Zomwe zikuchitikazi zikutsegulira njira zamakachitidwe anzeru oyendetsera magalimoto omwe amaphatikiza luntha lochita kupanga komanso kusanthula kwanthawi yeniyeni kuti apititse patsogolo kuyenda kwa magalimoto ndikuwonjezera kuyendetsa bwino kwamayendedwe.

Mapeto

Kuyambira pa zizindikiro zoyambirira za manja za Roma wakale mpaka njira zamakono zamakono zowongolera magalimoto, magetsi amsewu nthawi zonse akhala maziko osungitsa bata pamsewu. Pamene mizinda ikukulirakulirabe komanso zoyendera zikuyenda bwino, mosakayika magetsi amsewu adzagwira ntchito yofunika kwambiri poonetsetsa kuti anthu akuyenda motetezeka m'mibadwo ikubwerayi.

Qixiang, wopanga magetsi oyendera magalimoto, ali ndi kafukufuku wambiri paukadaulo wa LED. Akatswiriwa akhala akudzipereka kuti awone moyo wautali wa magetsi amtundu wa LED kwa zaka zambiri, ndipo ali ndi luso lopanga kupanga. Ngati muli ndi chidwi ndi kuwala kwa magalimoto, talandiridwa kuti mutilankhule nafeWerengani zambiri.
