I roto i ō tātou ao hou, kua noho ngā mana mamao pūwero hei taputapu watea mō tātou ki te whakahaere i ngā taputapu o te whare. Mai i ngā pouaka whakaata ki ngā hauhautanga, tae atu ki ngā kaitākaro rongorau maha, kua horapa te whakamahinga o te hangarau pūwero. Heoi, kāore i te tino mōhiotia te kaupapa mahi o te mana mamao pūwero, inā koa te tukanga whakarerekētanga me te tango i ngā whakarerekētanga. Ka rukuhia e tēnei tuhinga te tukatuka tohu o te mana mamao pūwero, e whakaatu ana i tōna tikanga whakawhitiwhiti kōrero whai hua me te pono.
Te Whakarerekētanga: Te Wāhanga Whakarite o te Tohu
Ko te whakarerekētanga te taahiraa tuatahi o te tuku tohu, arā, ko te huri i ngā mōhiohio whakahau ki tētahi hōputu e tika ana mō te tuku ahokore. I roto i tētahi mana mamao pūwero, ka mahia tēnei tukanga mā te whakamahi i te Pulse Position Modulation (PPM).
Ngā Mātāpono o te Whakarerekētanga PPM
He tikanga whakarerekētanga māmā te PPM e kawe ana i ngā mōhiohio mā te whakarerekē i te roa me te tawhiti o ngā pāorooro. He waehere ahurei kei ia pātene i runga i te mana mamao, ā, i roto i te PPM ka hurihia hei raupapa tohu pāorooro. Ka rerekē te whānui me te tawhiti o ngā pāorooro i runga i ngā ture waehere, kia mōhiotia ai te ahurei me te māmā o te tohu.
Te Whakarerekētanga Kawe
I runga i te PPM, me whakarerekē anō hoki te tohu ki tētahi auau kawe motuhake. Ko te auau kawe noa ko te 38kHz, he auau e whakamahia whānuitia ana i roto i ngā mana mamao infrared. Ko te tukanga whakarerekētanga ko te huri i ngā taumata teitei me te iti o te tohu kua whakakōnaetia ki ngā ngaru hikohiko o te auau e rite ana, e āhei ai te tohu ki te horapa atu i te rangi me te whakaiti i te pokanoa.
Te Whakarei me te Tukunga Tohu
Ka whakanuia te tohu kua whakarerekētia mā te whakakaha hei whakarite kia nui te mana mō te tuku ahokore. Hei whakamutunga, ka tukuna te tohu mā te diode whakaputa infrared (LED), ka hanga he ngaru mārama infrared e tuku ana i ngā whakahau whakahaere ki te taputapu ūnga.
Te Whakakorenga: Te Whiwhinga Tohu me te Whakaora
Ko te whakahekenga oro te tukanga whakahurihuri o te whakarerekētanga, e kawenga ana mō te whakahoki mai i te tohu i whiwhihia ki ngā mōhiohio whakahau taketake.
Te Whiwhinga Tohu
Ka whiwhi te diode tango infrared (Photodiode) i te tohu infrared ka tukuna, ka huri hei tohu hiko. He hononga matua tēnei taahiraa i roto i te tukanga tuku tohu nā te mea ka pā tika ki te kounga me te tika o te tohu.
Te Tātari me te Whakakorenga
Tērā pea he haruru kei roto i te tohu hiko e whiwhihia ana, ā, me tukatuka mā te tātari hei tango i te haruru me te pupuri i ngā tohu tata ki te auau kawe. Muri iho, ka kitea e te demodulator te tūranga o ngā pātere e ai ki te mātāpono PPM, ka whakahokia mai ngā mōhiohio taketake kua whakakōnaetia.
Te Tukatuka Tohu me te Wetewaehere
Tērā pea me tukatuka anō te tohu kua tangohia te oro, pērā i te whakanui me te hanga, kia mau tonu ai te pumau me te tika o te tohu. Kātahi ka tukuna te tohu kua tukatukahia ki te pūmana iti hei wetewete, e tautuhi ana i te waehere tautuhi taputapu me te waehere whakahaere e ai ki ngā ture waehere kua whakaritea.
Te Whakatinanatanga o ngā Whakahau
Kia angitu te wetewete, ka whakahaerehia e te pūmana iti ngā tohutohu e rite ana i runga i te waehere whakahaere, pērā i te whakahaere i te pana o te taputapu, te whakatikatika oro, me ētahi atu. Mā tēnei tukanga ka oti te tuku tohu o te mana mamao pūwhero.
Whakamutunga
Ko te tukanga whakarerekētanga me te tango i ngā whakarerekētanga o te mana mamao pūwero te kaupapa matua o tana tikanga whakawhitiwhiti kōrero whai hua me te pono. Mā tēnei tukanga, ka taea e tātou te whakatutuki i te whakahaere tika o ngā taputapu o te whare. I te whanaketanga tonu o te hangarau, kei te whakapai tonuhia, kei te whakahoutia hoki ngā mana mamao pūwero kia tutuki ai ā tātou hiahia whakahaere e tipu haere ana. Mā te mārama ki tēnei tukanga, ehara i te mea ka āwhina i a tātou ki te whakamahi pai ake i ngā mana mamao pūwero, engari ka taea hoki e tātou te whai māramatanga hohonu ake mō te hangarau whakawhitiwhiti kōrero ahokore.
