Iyo Bluetooth Module Inoshanda sei?

Ikozvino kukurumidza kukura kweInternet, iyo Internet yezvinhu iri kuramba ichienderera mberi kuunza kurerukirwa kukuru kuhupenyu hwevanhu. Mazuva ano, zvigadzirwa zveIoT zvakawanda, senge ma LED controller uye akangwara magetsi, ane maBluetooth module, saka iyo module yeBluetooth inoshanda sei?

Chii chinonzi Bluetooth module

A Bluetooth module chishandiso chinokwanisa kupfupi-renji isina waya kutaurirana pakati pemidziyo yemagetsi. Inowanzo shandiswa kugadzira hukama pakati pemidziyo yakadai semafoni, malaptop, mahedhifoni uye maIoT zvishandiso. Iyo Bluetooth module inoshanda yakavakirwa pane isina waya tekinoroji standard inonzi Bluetooth, iyo yakagadzirirwa yakaderera-simba, pfupi-renji kutaurirana.

Iyo bluetooth module inoshanda sei

Nheyo yekushanda yeBluetooth module ndeye kushandisa Bluetooth mudziyo neredhiyo kubatanidza nhare mbozha uye komputa kuendesa data. Zvigadzirwa zveBluetooth zvinosanganisira mamodule eBluetooth, maredhiyo eBluetooth uye software. Kana midziyo miviri ichida kubatanidza uye kuchinjana pamwe chete, inofanira kupetwa. Pakiti yedata inotumirwa uye data packet inogamuchirwa pane imwe chiteshi, uye mushure mekutapurirana, zvinodikanwa kuramba uchishanda pane imwe chiteshi. Kuwanda kwayo kwakanyanya, saka usazvinetse nezvekuchengetedza data.

Nheyo yekushanda yeBluetooth module ndeyotevera:

1. Bluetooth tekinoroji chiyero: Tekinoroji yeBluetooth inoshanda zvichibva pane yakatarwa seti yemitemo uye mapuroteni anotsanangurwa neBluetooth Special Interest Group (SIG). Aya maprotocol anotsanangura kuti zvishandiso zvinofanirwa kutaurirana sei, kumisikidza kubatana uye kuchinjanisa data.

2. Frequency Hopping Spread Spectrum (FHSS): Kukurukurirana neBluetooth kunoshandisa Frequency Hopping Spread Spectrum (FHSS) kudzivirira kukanganiswa kubva kune mamwe mawaya emagetsi anoshanda mune imwechete frequency bhendi. Zvishandiso zveBluetooth zvinosvetuka pakati akati wandei mukati meiyo 2.4 GHz ISM (Industrial, Sainzi, uye Medical) bhendi kudzikisa mukana wekukanganisa.

3. Basa remudziyo: Mukukurukurirana kweBluetooth, mudziyo unotamba basa chairo: tenzi mudziyo uye mudziyo wenhapwa. Iyo tenzi mudziyo unotanga uye unodzora kubatana, nepo muranda mudziyo unopindura kune zvikumbiro zvatenzi. Iyi pfungwa inobvumira kudyidzana kwakasiyana kwemidziyo senge-kune-imwe kana imwe-kune-yakawanda yekubatanidza.

4. Pairing uye kubatana: Zvishandiso zvinowanzopfuura nepakati pekuita maitiro vasati vakwanisa kutaurirana. Munguva yekubatanidza, zvishandiso zvinochinjana makiyi ekuchengetedza, uye kana zvikabudirira, zvinogadzira chinongedzo chakavimbika. Iyi nzira inobatsira kuve nechokwadi chekuti michina yakatenderwa chete ndiyo inogona kutaurirana.

5. Kumisikidzwa kwekubatanidza: Mushure mekubatanidza, zvishandiso zvinogona kumisikidza chinongedzo kana chiri mukati mechikamu cheumwe neumwe. Iyo tenzi mudziyo unotanga kubatana uye mudziyo wemuranda unopindura. Zvishandiso zvinotaurirana zvimiro zvakaita seye data uye mashandisiro emagetsi panguva yekubatanidza kuseta.

6. Kutsinhana kwedata: Mushure mekubatanidza kwasimbiswa, zvishandiso zvinogona kuchinjana data. Bluetooth inotsigira akasiyana maprofile uye masevhisi anotsanangura marudzi e data rinogona kuchinjana. Semuenzaniso, chimiro chisina maoko chinobvumira kutaurirana pakati pefoni nemaoko-isina mahedhifoni, nepo odhiyo / vhidhiyo kuremote control profile inogonesa kutonga kweaudiovisual michina.

7. Mapaketi edata: Dhata inotsinhaniswa muchimiro che data packet. Paketi yega yega ine ruzivo senge data payload, kukanganisa kutarisa makodhi, uye ruzivo rwekuwiriranisa. Aya mapaketi edata anofambiswa pamusoro pemasaisai eredhiyo, kuve nechokwadi chekutaura kwakavimbika uye kusina kukanganisa.

8. Power manejimendi: Bluetooth yakagadzirirwa kushomeka-simba kutaurirana, ichiita kuti ive yakakodzera kune bhatiri-powered zvishandiso. Zvishandiso zveBluetooth zvinoshandisa nzira dzakasiyana-siyana dzekuchengetedza simba, sekudzikisa simba rekutapurirana uye kushandisa nzira dzekurara kana usinga nyatso kufambisa data.

9. Chengetedzo: Bluetooth ine maficha ekuchengetedza kuchengetedza data panguva yekufambisa. Encryption uye yechokwadi inoshandiswa kuve nechokwadi chekuti data inotsinhaniswa pakati pemidziyo inoramba yakavanzika uye yakachengeteka.

Maitiro ekusarudza iyo Bluetooth module

Panguva ino, tekinoroji yeBluetooth yakatopinda mumatanho ese ehupenyu. Zvigadzirwa zvemabhizinesi zvinosanganisira makiyi egonhi akangwara, machira emwenje, mabara emwenje, fodya yemagetsi, maindasitiri otomatiki control uye zvinenge zvese zvinofungwa. Asi kune vatengi, iyo yakanakisa inokodzera zvigadzirwa zvavo, uye ndiyo yakangwara sarudzo yekusarudza zvinoenderana nezvavanoda.

1. Iyo Bluetooth module ine basa rekushandura iyo data yakagamuchirwa kubva kune serial port kuita Bluetooth protocol uye kuitumira kune Bluetooth mudziyo werimwe bato, uye kushandura iyo Bluetooth data packet yakagamuchirwa kubva kuBluetooth mudziyo werimwe bato kuita serial port data uye kutumira kune mudziyo.

2. Sarudza mamodule eBluetooth ane akasiyana anoshanda mamodule zvinoenderana nemaitiro ekutapurirana. Kana iyo inoshandiswa kutumira data, unogona kusarudza poindi-ku-point transparent transparent module, uye point-to-multipoint module, yakadai seJonett low-power Bluetooth module.

3. Sarudza maererano nepepaji fomu. Kune marudzi matatu eBluetooth modules: in-line mhando, pamusoro pegomo mhando uye serial port adapter. Iyo ye-in-line mhando ine pini, iyo inobatsira kune yekutanga soldering uye diki batch kugadzirwa. Kune maviri magungano mafomu eakavakirwa-mukati uye ekunze mamodule. Mukuwedzera, kune zvakare serial Bluetooth adapta muchimiro chekubatana kwekunze. Kana vatengi vasingakwanisi kuvaka Bluetooth mumudziyo, vanogona kubatanidza adapta mune serial port yemudziyo, uye inogona kushandiswa pakarepo mushure memagetsi.

Iko kukosha kwekushandisa kweBluetooth module

Iyo yakaderera simba rekushandisa maitiro eiyo Bluetooth module inobvumira iyo Bluetooth module kuratidza kukosha kwayo kwakasiyana mumaindasitiri mazhinji matsva, kubva kumagetsi evatengi kuenda kumagetsi ekurapa, kubva kumba kwakangwara kuenda kumaindasitiri ekushandisa, Bluetooth yakaderera simba rekushandisa modules yakatoshandiswa muInternet. Zvinhu indasitiri yemusika zvine basa rakakosha. Chimiro chakadaro zvakare isarudzo yakanakisa yemasensa, uye iyo Indaneti yeZvinhu uye makore ekubatanidza anozongoerekana avapo, kuitira kuti maBluetooth midziyo inogona kubatana kune zvese uye kubatana neInternet.

Izvo zviri pamusoro ndiyo nheyo yekushanda yeBluetooth module yakagovaniswa ne Joinet Bluetooth module  Mugadziri , uye zvimwe zvirimo zveBluetooth module zvinowedzerwawo kune wese munhu. Kana iwe uchida kuziva rumwe ruzivo nezve bluetooth module, ndapota taura nesu.
