Nigute RF 433/868 Imenyekanisha ry'umwotsi rihuza hamwe na paneli yo kugenzura?
Ufite amatsiko yukuntu impuruza itagira umwotsi wa RF itahura umwotsi kandi ikamenyesha akanama ko hagati cyangwa sisitemu yo gukurikirana? Muri iyi ngingo, tuzasenya ibice byingenzi bigize anImpuruza ya RF, kwibanda ku buryoMCU (microcontroller) ihindura ibimenyetso bisamu mibare ya sisitemu, ikoresha algorithm ishingiye ku mbibi, hanyuma ibimenyetso bya digitale bihindurwamo ibimenyetso bya 433 cyangwa 868 RF binyuze muburyo bwo guhindura FSK hanyuma byoherezwa mukibaho kigenzura gihuza module imwe ya RF.
1. Kuva Kumenya Umwotsi Kuri Guhindura Data
Hagati yumwotsi wa RF ni aicyuma gifata amashanyaraziibyo bigira ingaruka kumyuka yumwotsi. Rukuruzi rusohora ananalog voltageugereranije n'ubucucike bw'umwotsi. AnMCUmu gutabaza ikoreshaADC (Analog-to-Digital Converter)guhindura iyi analogi voltage mubiciro bya digitale. Mugukomeza gutoranya ibyo bisomwa, MCU ikora amakuru nyayo yibipimo byumwotsi.
2. MCU Threshold Algorithm
Aho kohereza sensor zose zisoma kuri transmitter ya RF, MCU ikora analgorithmkugirango umenye niba urwego rwumwotsi rurenze igipimo cyateganijwe. Niba kwibandaho biri munsi yurugero, impuruza iraceceka kugirango wirinde ibinyoma cyangwa ibibi. Rimwegusoma bya digitale birarenzeurwo rugabano, MCU ishyira mubikorwa nkibishobora guteza inkongi y'umuriro, bigatera intambwe ikurikira mubikorwa.
Ingingo z'ingenzi za Algorithm
Akayunguruzo k'urusaku: MCU yirengagije imitwe yinzibacyuho cyangwa ihindagurika rito kugirango igabanye ibinyoma.
Kugereranya no Kugenzura Igihe: Ibishushanyo byinshi birimo idirishya ryigihe (urugero, gusoma mugihe runaka) kugirango hemezwe umwotsi uhoraho.
Kugereranya: Niba impuzandengo cyangwa impinga yo gusoma ihora hejuru yurugero rwashyizweho, logique yo gutabaza itangiza umuburo.
3. Ikwirakwizwa rya RFI binyuze kuri FSK
Iyo MCU igennye ko impuruza yujujwe, yohereza ibimenyetso byo kumenyesha binyuzeSPIcyangwa ubundi buryo bwitumanaho kuri anChip transceiver chip. Iyi chip ikoreshaFSK (Urufunguzo rwo Guhindura inshuro)Guhindura CYANGWABAZA (Urufunguzo rwa Amplitude-Shift)gushishoza amakuru yimibare yamakuru kuri frequency yihariye (urugero, 433MHz cyangwa 868MHz). Ikimenyetso cyo gutabaza noneho cyoherezwa mu buryo butemewe mu gice cyakira - muri rusange aakanama gashinzwe kugenzuracyangwasisitemu yo gukurikirana—Ahantu hose hasobanuwe kandi ikerekanwa nkumuriro.
Kuki Guhindura FSK?
Ikwirakwizwa rihamye: Guhindura inshuro kuri 0/1 bits birashobora kugabanya kwivanga mubidukikije bimwe.
Amasezerano yoroheje: Gahunda zitandukanye zamakuru-kodegisi zirashobora gushirwa hejuru ya FSK kubwumutekano no guhuza.
Imbaraga nke: Birakwiriye kubikoresho bikoreshwa na bateri, kuringaniza urwego no gukoresha ingufu.
4. Uruhare rw'akanama gashinzwe kugenzura
Kuruhande rwakira, akanama gashinzwe kugenzuraModule ya RFyumve kumurongo umwe. Iyo itahuye kandi ikanerekana ibimenyetso bya FSK, imenya indangamuntu idasanzwe cyangwa aderesi, hanyuma igatera urusaku rwibanze, kumenyesha urusobe, cyangwa kubimenyeshwa. Niba urubibi rwateje impuruza kurwego rwa sensor, akanama gashobora guhita kamenyesha abashinzwe umutungo, abashinzwe umutekano, ndetse na serivisi ishinzwe gukurikirana byihutirwa.
5. Impamvu ari ngombwa
Kugabanya Impuruza: Algorithm ya MCU yinjirira ifasha gushungura inkomoko yumwotsi cyangwa ivumbi.
Ubunini: Impuruza za RF zirashobora guhuza kumwanya umwe ugenzura cyangwa gusubiramo byinshi, bigafasha kwizerwa mumitungo minini.
Porotokole yihariye: Ibisubizo bya OEM / ODM reka ababikora bashireho kode ya RF niba abakiriya bakeneye umutekano wihariye cyangwa kwishyira hamwe.
Ibitekerezo byanyuma
Muguhuza hamweGuhindura amakuru,MCU ishingiye kuri algorithms, naIkwirakwizwa rya RF (FSK), uyumunsi umwotsi wumwotsi utanga uburyo bwizewe bwo kumenya no guhuza simusiga. Waba uri umuyobozi wumutungo, uhuza sisitemu, cyangwa ufite amatsiko gusa kubijyanye nubwubatsi inyuma yibikoresho byumutekano bigezweho, gusobanukirwa uruhererekane rwibintu - uhereye kubimenyetso bisa kugeza kuri digitale - byerekana uburyo ibyo byapa byateguwe neza.
Komeza ukurikiranekubindi byimbitse byikoranabuhanga rya RF, guhuza IoT, hamwe nibisubizo byumutekano bizakurikiraho. Kubibazo byerekeranye na OEM / ODM bishoboka, cyangwa kugirango umenye uburyo sisitemu ishobora guhuzwa nibyifuzo byawe byihariye,vugana nitsinda ryacu rya tekinikiUyu munsi.
