Domestic spread spectrum anti-interference low cost serial port 433M wireless communication module Lora remote UART AD hoc network

Umsebenzi wesici

Ngokusekelwe ku-chip yasekhaya ehlanzekile yamandla aphansi yebanga elide yokusabalalisa i-spectrum PAN3028, ibanga lokuxhumana lide futhi nekhono lokulwa nokuphazamiseka liqinile; Ukudluliselwa okumsulwa nokusobala, ukuzivumelanisa ngokugcwele nezidingo zamakhasimende ezahlukene; Ukuvuka kwesilawuli kude ukuze kuzuzwe ukusetshenziswa kwamandla aphansi kakhulu, afanele izimo zohlelo lokusebenza olusebenza ngebhethri; Ukusekela ukuphrinta kwesignali ye-RSSI, okusetshenziselwa ukuhlola ikhwalithi yesignali, ukuthuthukisa umphumela wokuxhumana nezinye izinhlelo zokusebenza;

Isekela ukulala ubuthongo obujulile. Incanyana yamandla yemojuli ekujuleni kokulala i-3UA. Ukusekela ukunikezwa kwamandla ka-3 ~ 6V, ukunikezwa kwamandla angaphezu kuka-3.3V kungaqinisekisa ukusebenza okuhle kakhulu; Idizayini yezinti ezimbili esekela i-IPEX nezimbobo zezitembu; Izinga nokusabalala kwe-spectrum factor kungalungiselelwa ngokungenasisekelo ngokuya ngokwesimo sokusetshenziswa sangempela. Ngaphansi kwezimo ezinhle, ibanga lokuxhumana lingafinyelela ku-6 km; Amandla ayalungiseka ngezigaba eziningi.

Sebenzisa okokufundisa

Imojula ye-CL400A-100 iyimojula yokudlulisela esobala emsulwa engena ngokuzenzakalelayo kumodi yokudlulisela esobala ngemva kokukhanyisa. Uma amapharamitha ahambisanayo emojula adinga ukumiswa futhi alungiswe, umyalo ohambisanayo we-AT ungathunyelwa ngokuqondile (bheka imiyalelo ye-AT esethelwe imininingwane). Imojula isekela izindlela ezintathu zokusebenza, okuyimodi yokudlulisa ejwayelekile, imodi yokulala eqhubekayo, kanye nemodi yokulala ngezikhathi ezithile.

1. Imodi yokudlulisa ejwayelekile:

Donsela phansi iphinikhodi ye-SLEEP, amandla avuliwe angena ngokuzenzakalelayo kumodi yokudlulisa jikelele, NGALESI sikhathi imojula ibisesimweni sokwamukela esijwayelekile, ingathola amasignali angenantambo noma idlulise amasignali angenantambo, kule modi ingathumela ngokuqondile imiyalelo ye-AT ehambisanayo, wena ingashintsha imingcele ye-module (ukushintsha imingcele ye-module ingenziwa kuphela kule modi, ezinye izindlela azikwazi ukushintshwa).

2, imodi yokulala njalo:

Kudingeka ukusetha ipharamitha yemojula ku-AT+MODE=0 kumodi yokudlulisela evamile, bese ulawula iphinikhodi YOKULALA ukuze idonse, futhi imojula ingangena kumodi yokulala eqhubekayo. Ngalesi sikhathi, imojula idla amandla aphansi kakhulu, imojuli isesimweni sokulala okujulile, futhi akukho datha ezothunyelwa noma ezotholwa. Uma imojuli idinga ukuqala ukusebenza, iphinikhodi ye-SLEEP idinga ukudonswa phansi.

3. Imodi yokulala ngezikhathi ezithile:

Ku-MODE yokudlulisela evamile, setha ipharamitha yemojula ku-AT+MODE=1, bese ulawula iphinikhodi ethi SLEEP ukuze uyiphakamise, futhi imojuli ingangena kumodi yokulala yezikhathi ezithile. Ngalesi sikhathi, imojula isesimweni esishintshanayo sokulinda ukuphumula - i-hibernation standby - hibernation. Isikhathi esiphezulu sokulala singama-6S, futhi kunconywa ukuthi singadluli i-4S, ngaphandle kwalokho imojuli yokuthumela izoshisa kakhulu. Futhi imojuli yokuthumela idinga inani le-PB ukuthi libe likhulu kunesikhathi sokulala.
