Ko te taumata tētahi o ngā tawhā whāinga nui o te aroturukitanga tukanga ahumahi. I roto i te ine taumata tonu o ngā tāke, ngā silo, ngā puna kaukau, me ētahi atu, he uaua ki te whai taputapu taumata e taea ai te whakatutuki i ngā āhuatanga mahi katoa nā te whānuitanga o ngā āhuatanga o te mara.
I roto i ēnei, he whānuitia te whakamahinga o ngā ine taumata radar me te ultrasonic i roto i ngā taputapu ine kore-pā. Nā, he aha te rerekētanga i waenga i te mita taumata radar me te mita taumata ultrasonic? He aha te kaupapa matua o ēnei momo ine e rua? He aha ngā painga o te mita taumata radar me te mita taumata ultrasonic?
Tuatahi, mita taumata ultrasonic
Ko te tikanga, he ngaru oro neke atu i te 20kHz te auau e kiia nei e tātou he ngaru ultrasonic, he momo ngaru miihini, arā, he wiri miihini i roto i te reo rapa i roto i te tukanga horapa. Ko tōna āhuatanga he auau teitei, he roangaru poto, he iti te āhuatanga diffraction, me te ahunga pai, ka taea te huri hei hihi me te ahunga horapa.
He iti rawa te whakaiti o te ultrasonic i roto i ngā wai me ngā totoka, nō reira he kaha te kaha o te urunga, inā koa i roto i ngā totoka mārama, he mārama, ka taea e te ultrasonic te uru ki ngā tekau mita te roa, ka nui te whakaata ina tūtaki ki ngā poke, ki ngā atanga rānei, ā, ko tēnei āhuatanga te whakamahi i te ine taumata ultrasonic.
I roto i te hangarau kimi i te ultrasonic, ahakoa te momo taputapu ultrasonic, me huri te pūngao hiko ki te tukunga ultrasonic, kātahi ka whiwhi anō hei tohu hiko. Ko te taputapu hei whakaoti i tēnei mahi ka kiia he transducer ultrasonic, e mōhiotia ana hoki ko te ine.
I te wā e mahi ana, ka whakatakotoria te transducer ultrasonic ki runga ake i te mea i inehia, ka tukuna te ngaru ultrasonic ki raro. Ka haere te ngaru ultrasonic mā te reo hau, ka whakaatahia anō ina tūtaki ki te mata o te mea i inehia, ā, ka riro mai i te transducer ka hurihia hei tohu hiko. I muri i te kitenga i tēnei tohu, ka hurihia e te wāhanga kitenga hiko hei tohu taumata hei whakaatu me te whakaputa.
Tuarua, mita taumata radar
He rite tonu te aratau whakahaere o te mita taumata radar ki te mita taumata ultrasonic, ā, ka whakamahia hoki e te mita taumata radar te aratau mahi tuku - whakaata - whiwhi. Ko te rerekētanga ko te ine o te mita taumata ultrasonic radar e whakawhirinaki ana ki te transducer ultrasonic, ko te mita taumata radar ia e whakawhirinaki ana ki te pane auau-tiketike me te pūihi.
Ka whakamahia e ngā mita taumata orooro ngā ngaru ā-ringa, ko ngā mita taumata radar ia ka whakamahia ngā ngaru hikohiko auau tino teitei (e hia ki te tekau o ngā G Hertz). Ka haere ngā ngaru hikohiko i te tere o te mārama, ā, ka taea te huri i te wā haere hei tohu taumata mā ngā wāhanga hiko.
Ko tētahi atu mita taumata radar e whakamahia whānuitia ana ko te mita taumata radar ngaru ārahi.
Ko te mita taumata radar ngaru ārahi he mita taumata radar e hangai ana ki te mātāpono whakaata rohe wā (TDR). Ka horapa te pāorooro hikohiko o te mita taumata radar i te taura maitai, i te tere rānei o te mārama. Ina tūtaki ki te mata o te reo inehia, ka whakaatahia tetahi wāhanga o te pāorooro o te mita taumata radar hei hanga i te whakaata, ā, ka hoki ki te taputapu whakarewa pāorooro i te ara kotahi. Ko te tawhiti i waenga i te tuku me te mata reo inehia he rite ki te wā horapa o te pāorooro i te wā e tatauhia ai te teitei o te taumata wai.
Tuatoru, ngā painga me ngā ngoikoretanga o te radar me te mita taumata ultrasonic
1. Kāore te tika o te orooro i te rite te pai ki te radar;
2. Nā te whanaungatanga i waenga i te auau me te rahi o te pūihi, he iti ake, he māmā ake hoki te tāuta i te mita taumata radar he nui ake te auau;
3. Nā te mea he teitei ake te auau o te radar, he poto ake te roanga ngaru, ā, he pai ake te whakaata i runga i ngā mata totoka e piko ana;
4. He iti ake te horahanga matapo o te ine radar i te ultrasonic;
5. Nā te nui ake o te auau radar, he iti te koki o te hihi radar, he kukū te pūngao, ā, ka whakarei ake i te kaha o te whakaata, ā, he pai hoki mō te karo i te pokanoa;
6. Ki te whakatauritea ki ngā mita taumata ultrasonic e whakamahi ana i ngā ngaru miihini, kāore te radar e pāngia e te korehau, te mamaoa wai i te rangi, te puehu (haunga te graphite, te ferroalloy me ētahi atu puehu dielectric teitei), ngā huringa pāmahana me te pēhanga;
