Anns an artaigil an-diugh tha mi airson pròiseact ùr a roinn leat. An turas seo is e suidse suathaidh a th’ ann le pannal glainne. Tha an inneal teann, a’ tomhas 42x42mm (tha meudan pannalan glainne àbhaisteach 80x80mm). Thòisich eachdraidh an inneal seo o chionn fhada, timcheall air bliadhna air ais.
Bha a’ chiad roghainnean air an atmega328 microcontroller, ach aig a’ cheann thall thàinig e gu crìch leis an microcontroller nRF52832.
Bidh am pàirt suathaidh den inneal a’ ruith air sgoltagan TTP223. Tha an dà sensor air an toirt seachad le aon bhriseadh. Le cumhachd bataraidh CR2477, tro inneal-tionndaidh àrdachadh air a’ chip TPS610981 | .
Bidh an inneal a’ cur an gnìomh cuairt cumhachd dheth a’ cleachdadh transistors buaidh achaidh. Às deidh putadh air a ’phutan, bidh am microcontroller fhèin a’ toirt a-steach smachd cumhachd agus an uairsin faodar am putan a chleachdadh airson modhan seirbheis (anns a ’chùis agam, tha seo a’ dol còmhla ri innealan eile, a ’tionndadh a’ chumhachd agus ag ath-shuidheachadh gu suidheachadh factaraidh).
Tha 2 rgb LED ann airson stàitean agus modhan seirbheis a chomharrachadh. Chaidh emitter piezo a chuir ris cuideachd gus atharrais air cliog nuair a bhios tu a’ suathadh air putanan suathaidh agus deagh chomharradh air modhan seirbheis. Faodar na LEDs agus piezo emitter a thionndadh air agus dheth a rèir toil an neach-cleachdaidh. Tha seo air a dhèanamh tro rianadair dachaigh smart le bhith a’ cur òrdughan gu mothachairean teignigeach; faodaidh an neach-cleachdaidh cuideachd na h-amannan atharrachadh airson cosgais bataraidh agus ìre chomharran a chuir cuideachd tro rianadair an dachaigh spaideil. Anns a 'chùis agam tha e .
Is e caitheamh ann am modh tar-chuir 7mA (250kbit, 10ms), is e caitheamh ann an cadal 40µA, tha caitheamh anns an stàit dheth nas lugha na 1µA (= caitheamh an inneal-tionndaidh àrdachadh ann am modh “idle”). Tha ceangal Rx, tx, swd airson prògramadh air a thoirt seachad. Thathas a’ cleachdadh inneal-ceangail beag 2x3p le pitch de 1.27. Tha inneal-atharrachaidh sònraichte air a dhèanamh airson prògramadh.
Mar as àbhaist, tha obrachadh an inneil stèidhichte air a’ phròtacal . Thathas an dùil an suidse suathaidh seo a chleachdadh anns an t-siostam smachd rolair dall. Ach san fharsaingeachd, tha an tagradh air a chuingealachadh a-mhàin le do mhac-meanmna. Mar eisimpleir, tha mo mhac (7 bliadhna a dh'aois) air 3 òrdughan a dhèanamh mu thràth airson dreachan suidse: an solas a thionndadh air agus dheth ann an taigh-beag le bathtub (bidh e air a chuir sìos bhon ùrlar), gus an solas a chuir air. trannsa fada is dorcha nuair a bhios tu a’ siubhal gu taigh-beag le bathtub, agus fear eile ri taobh na leapa, airson an solas anns an t-seòmar agad a thionndadh gu sgiobalta gus am bi na h-uilebheistean a’ ruith air falbh.
Chaidh a ’chùis a chlò-bhualadh gu traidiseanta air clò-bhualadair SLA, tha an inneal beag, thionndaidh a’ chùis a-mach gu bhith beag, tha cleachdadh an teicneòlais clò-bhualaidh seo air fhìreanachadh.
Seall am modail clò-bhuailte
Tha magnets air an glaodhadh a-steach don chùis agus còmhdach roinn a ’bhataraidh.
