Kakau takirere whakahaere pairati hiko o te keri

I roto i te ngaru o te panonitanga atamai o ngā mīhini hanga, kua noho te kakau takirere whakahaere pairati hiko keri hei arotahi o te ahumahi me tōna tūnga mahi tika, tōna āheinga whānui ki te urutau ki ngā tirohanga me ngā āhuatanga hangarau tino pai. Ko tēnei wāhanga auaha e whakauru ana i te mana hiko me te mahi miihini e whakarato ana i ngā otinga whai hua mō ngā mahi hangarau i raro i ngā āhuatanga mahi rerekē mā te arotau i te mahi puta noa.

He pūmau te pūngao hiko hei whakarite kia pono te mahi a ngā taputapu

Mō te pūtake hiko, he tino pai te urutau o tēnei kakau takirere whakahaere. Ko te whānuitanga o te ngaohiko o te pūtake hiko he 10-32VDC, ā, ka taea te mahi pumau i roto i ngā momo taiao pūtake hiko, ahakoa i roto i ngā āhuatanga mahi kore pumau o te pūtake hiko rangitahi i te parae, i roto rānei i ngā āhuatanga tuku iho me te whirihoranga pūtake hiko paerewa, ka taea e ia te whakarite kia mahi noa te taputapu. I taua wā anō, he tino pai ngā āhuatanga o te iti o te whakamahinga o te au, 100mA noa iho, iti iho rānei, e tino whakaiti ana i te whakamahinga pūngao o te taputapu, e whakapai ake ana i te whai huatanga o te whakamahinga pūngao. Ko te au pāhekoheko he iti iho rānei ki te 10A, iti iho rānei, e ārai ana i te kino o ngā taputapu i puta mai i te ru nui o te au, ā, e whakarite ana i te haumaru me te pumau o te pūnaha hiko katoa.

Tuku tohu whai hua mō te whakahaere tika

Ko te wāhanga whakaputa tohu tētahi o ngā mea nui o tēnei hua. Mā te whakamahi i te kawa whakawhitiwhiti CAN (SAE J1939) EJM1, kua whakatakotoria te wāhitau pūtake ki te 249, ko te tere whakawhitiwhiti tae atu ki te 250kbps, ā, me te wā tauira o te 10ms, ka taea te tuku tere me te tika i ngā tohutohu whakahaere ki te pūnaha whakahaere keri. Mā tēnei ka taea te whakahoki i ia mahi a te kaiwhakahaere ki ngā taputapu i roto i te wā tika me te wā tika, ka tutuki ai te tika o te mahi taumata mirimita. He tino pai hoki te tika o te putanga i raro i ngā taiao pāmahana rerekē. I roto i te taiao -10 – +50°C, ka taea e te tika waenga te eke ki te ±2%, ā, i roto i te taiao -40 – +75°C, ka taea hoki te pupuri i te ±3%, kia taea ai e te taputapu te mahi i ngā mahi me te pumau me te tika i roto i ngā taiao uaua.

Ngā tawhā miihini tino tika, te roa me te whakamarie

Mai i te tirohanga o ngā tawhā mahi ā-mīhini, he pai hoki te mahi a te kakau takirere whakahaere. Ko tōna hysteresis e whakahaeretia ana i te ±1.6%, iti iho rānei, ā, ko te rerekētanga waenga ā-mīhini he 0.5°, iti iho rānei, e pai ai te ahua o te mahi a te kakau, e tere ai te mahi, e whakaiti ana i ngā hapa whakahaere, e whakapai ake ana i te whakamarie me te tika o te mahi. Ko te awhe pāmahana ratonga he -40-75°C, ka taea te urutau ki ngā taiao tino kino mai i ngā rohe pōuri makariri ki ngā koraha wera, e whakawhānui ana i ngā āhuatanga tono o te taputapu. Ko te taipana whakahaere mōrahi he 226N/m, e whakarite ana kia pakari te kakau ki te tu atu i te whakamahinga kaha nui, me te whakarite hoki i te kaha whakahaere tika.

Ngā tohutohu pana atamai, te wheako whakahaere kua arotauhia

Mō ngā tohutohu mō te pana, kua āta hangaia hoki te hua. E rua ngā whakatakotoranga mō te ngaohiko me te iahiko kua whakatauria: DC30V/3A (kawenga ātete) me DC30V/1A (kawenga ātete). Ko te kaha iti rawa o te tango ko DC5V/160mA me DC30V/26mA. Ka whakaritea hoki te kaha whakahaere me te kaha whakahaere kia rite ki ngā pana rerekē, pērā i te pana 1 me te 3 he 1mm/4N, ā, ko te pana 2 he 1mm/6N. Mā ēnei tawhā ka ātaahua te mahi a te pana, ka penapena mahi hoki, ka pai ake te wheako o te kaiwhakahaere. I taua wā anō, ko te pāmahana ratonga he – 40 – 75°C, e whakarite ana i te pumau me te pono o te mahi pana i roto i ngā taiao rerekē.

He tino pai te mahi a tēnei kakau takirere whakahaere pairati hiko mō te keri i roto i te tuku hiko, te tuku tohu, te mahi miihini me ngā tohutohu pana, e kore e kore ka whakaratohia he taurangi pakari mō te mahi atamai me te tika o te keri. Mā te whakatairanga me te whakamahinga āta haere i te mākete, ka tino whakatairangahia te umanga mīhini hanga ki tētahi taumata teitei ake, ā, ka whakapiki ake i te pai me te kounga o ngā kaupapa hanga hangarau.
