Kune akawanda uye akawanda ma modules pamusika, asi anogona kukamurwa kuita zvikamu zvitatu:
1. Bvunza superheterodyne module: tinogona kushandiswa sechinhu chiri nyore chekudzivirira uye kutumira data;
2. Wireless transceiver module: Inonyanya kushandisa imwe-chip microcomputer kuti itonge wireless module kutumira uye kugamuchira data.Iyo inowanzoshandiswa modulation modes ndeyeFSK neGFSK;
3. Iyo wireless data transmission module inonyanya kushandisa serial port maturusi kugamuchira uye kutumira data, izvo zviri nyore kuti vatengi vashandise.Wireless modules pamusika ave kushandiswa zvakanyanya, ane ma frequency e230MHz, 315MHz, 433MHz, 490MHz, 868MHz, 915MHz, 2.4GHz, nezvimwe.
Ichi chinyorwa chinonyanya kusuma chimiro chekuenzanisa kwe433M uye 2.4G isina waya modules.Chekutanga pane zvese, isu tinofanirwa kuziva kuti frequency renji ye433M ndeye 433.05 ~ 434.79MHz, nepo frequency renji ye2.4G iri 2.4 ~ 2.5GHz.Iwo ese marezinesi-asina ISM (maindasitiri, sainzi uye ekurapa) akavhurika frequency mabhendi muChina.Izvo hazvifanirwe kushandisa aya ma frequency bands.Inoda kunyorera mvumo kubva kune yemuno redhiyo manejimendi, saka mabhendi maviri aya akashandiswa zvakanyanya.
Chii chinonzi 433MHz?
Iyo 433MHz isina waya transceiver module inoshandisa yakakwirira-frequency radio frequency tekinoroji, saka inonzi zvakare RF433 radio frequency module diki.Iyo inoumbwa neiyo imwe chete IC radio frequency kumberi kwekupedzisira inogadzirwa neye-digital tekinoroji uye ATMEL's AVR single-chip microcomputer.Inogona kufambisa masaini edatha nekumhanya kwakanyanya, uye inogona kurongedza, kutarisa uye kugadzirisa iyo data inofambiswa pasina waya.Izvo zvikamu zvese zveindasitiri-giredhi zviyero, yakagadzikana uye yakavimbika mukushanda, diki muhukuru uye nyore kuisa.Inokodzera nzvimbo dzakasiyana-siyana dzakadai seyekuchengetedza alarm, wireless otomatiki mita kuverenga, imba uye maindasitiri otomatiki, kure kure kure, wireless data transmission nezvimwe zvakadaro.
433M ine yakakwira yekugamuchira kunzwa uye yakanaka diffraction kuita.Isu tinowanzo shandisa 433MHz zvigadzirwa kuita master-varanda kutaurirana masisitimu.Nenzira iyi, iyo master-slave topology ichokwadi imba yakangwara, ine zvakanakira zveyakapusa network chimiro, nyore marongero, uye pfupi simba-panguva.433MHz uye 470MHz ikozvino inoshandiswa zvakanyanya muindasitiri yekuverenga mita yakangwara.
Kushandiswa kwe433MHz mumba yakangwara
1. Lighting Control
Iyo isina waya redhiyo frequency mwenje yekudzora sisitimu inoumbwa neye smart panel switch uye dimmer.Iyo dimmer inoshandiswa kutumira uye kugamuchira masaini ekuraira.Mirairo inofambiswa neredhiyo pachinzvimbo chetambo yemagetsi yepamba.Imwe neimwe pani switch inoshongedzerwa neyakasiyana kuremote control identification code.Aya macode anoshandisa 19-bit recognition tekinoroji kuita kuti mugamuchiri akwanise kuziva murairo wega wega.Kunyangwe kana vavakidzani vakaishandisa panguva imwe chete, hapazombovi nekukanganisa kwekutapurirana nekuda kwekukanganiswa kubva kure kure.
2. Wireless Smart Socket
Iyo isina waya smart socket yakatevedzana inonyanya kushandisa isina waya redhiyo frequency tekinoroji kuona kudzora kure kwesimba rezvisiri-remote control midziyo (senge maheater emvura, mafeni emagetsi, nezvimwewo), izvo zvisingango wedzera basa rewireless remote control kune izvi. midziyo, asi zvakare inochengetedza simba kusvika pamwero mukuru uye inovimbisa kuchengeteka.
3. Ruzivo rwekushandisa kudzora
Ruzivo rwekushandisa dhizaini ndeye multifunctional remote control system inobatanidza infrared control uye isina waya control.Inogona kudzora anosvika mashanu infrared zvishandiso (zvakadai se: TV, air conditioner, DVD, simba amplifier, maketeni, nezvimwewo) uye michina isina waya senge switch uye sockets.Iyo yeruzivo mudziyo controller inogona kutamisa macode eremote control yeyakajairwa infrared midziyo kuburikidza nekudzidza kutsiva yekutanga mudziyo wekushandisa remote control.Panguva imwecheteyo, iri zvakare isina waya yekudzora kure, iyo inogona kutumira masaini ekudzora ine frequency ye433.92MHz, saka inogona kudzora smart switch, smart sockets uye isina waya infrared transponders mune ino frequency band.
Iyo 2.4GHz application poindi itiweki protocol yakagadziridzwa zvichibva pane yayo yepamusoro-kumhanya yekufambisa mwero.
Zvese mune zvese, isu tinogona kusarudza mamodule ane akasiyana mafrequency zvinoenderana neakasiyana nzira dzenetwork.Kana nzira yekubatanidza iri nyore uye zvinodiwa zviri nyore, tenzi mumwe ane varanda vakawanda, mutengo wakaderera, uye nzvimbo yekushandiswa yakanyanya kuoma, tinogona kushandisa 433MHz wireless module;kutaura, kana network topology yakanyanya kuomarara uye inoshanda Zvigadzirwa zvakasiyana-siyana zvine simba rakasimba retiweki, kuderera kwesimba rekushandisa zvinodiwa, kusimudzira kuri nyore, uye 2.4GHz networking basa richava sarudzo yako yakanaka.
