Joang RF 433/868 Alamo ea Mosi e Hokahana le Liphanele tsa Taolo?
Na u labalabela ho tseba hore na alamo ea mosi ea RF e se nang mohala e hlile e lemoha mosi le ho lemosa karolo e bohareng kapa sistimi ea ho beha leihlo? Sehloohong sena, re tla arola likarolo tsa mantlha tsa aAlamo ea mosi oa RF, ho shebana le kamoo hoMCU (microcontroller) e fetola matšoao a analogho data ea dijithale, e sebelisa algorithm e thehiloeng ho threshold, ebe lets'oao la dijithale le fetoloa lets'oao la 433 kapa 868 RF ka mochini oa tokiso ea FSK ebe o romelloa phanele ea taolo e kopanyang module ea RF e tšoanang.
1. Ho tloha ho Fumana Mosi ho ea ho Phetoho ea Boitsebiso
Bohareng ba alamo ea mosi ea RF kesensor ea photoelectrice sebetsanang le boteng ba makumane a mosi. Sensor e fana ka tlhahiso eamatla a analogeka ho lekana le bongata ba mosi. AnMCUka hare ho alamo e sebelisa ea eonaADC (Sefetoleli sa Analog-to-Digital)ho fetola matla ana a analoge hore e be boleng ba dijithale. Ka ho tsoela pele ho etsa mohlala oa 'malo ona, MCU e theha lethathamo la lintlha tsa nako ea nnete tsa maemo a mahlonoko a mosi.
2. Algorithm ea MCU Threshold
Sebakeng sa ho romella 'malo o mong le o mong oa sensor ho RF transmitter, MCU e tsamaisaalgorithmho fumana hore na boemo ba mosi bo feta tekanyo e behiloeng esale pele. Haeba mahloriso a le ka tlase ho moeli ona, alamo e lula e khutsitse ho qoba li-alarms tsa bohata kapa tsa khathatso. Hang haho bala ka dijithale ho fetamoeli oo, MCU e e khetholla e le kotsi e ka bang teng ea mollo, e bakang mohato o latelang ts'ebetsong.
Lintlha tsa bohlokoa tsa Algorithm
Ho Sefa Lerata: MCU e hlokomoloha li-spikes tsa nakoana kapa liphetoho tse nyane ho fokotsa lialamo tsa bohata.
Karolelano le Liteko tsa Nako: Meralo e mengata e kenyelletsa fensetere ea nako (mohlala, ho bala ka nako e itseng) ho netefatsa mosi o phehellang.
Papiso ea Motheo: Haeba palohare kapa tlhoro ea ho bala e lula e le ka holimo ho moeli o behiloeng, mohopolo oa alamo o qala temoso.
3. Phetiso ea RF ka FSK
Ha MCU e etsa qeto ea hore boemo ba alamo bo fihletsoe, e romela letšoao la tlhokomeliso kaSPIkapa sehokelo se seng sa puisano ho ea hoRF transceiver chip. Sesebelisoa sena se sebetsaFSK (Frequency Shift Keying)modulation ORASK (Amplitude-Shift Keying)ho kenyelletsa data ea alamo ea dijithale ho maqhubu a itseng (mohlala, 433MHz kapa 868MHz). Joale lets'oao la alamo le fetisetsoa ka mohala ho yuniti e amohelang — hangata alekhotla la taolokapatsamaiso ea ho beha leihlo—moo e arotsoeng le ho bontšoa e le tlhokomeliso ea mollo.
Ke hobane'ng ha FSK Modulation?
Phetiso e tsitsitseng: Ho fetoha ha maqhubu bakeng sa li-bits tsa 0/1 ho ka fokotsa tšitiso libakeng tse itseng.
Li-Protocol tse Fetohang: Merero e fapaneng ea khouto ea data e ka beoa ka holim'a FSK bakeng sa ts'ireletso le ts'ebelisano.
Matla a Tlase: E loketse lisebelisoa tse tsamaisoang ke betri, sebaka sa ho leka-lekanya le tšebeliso ea matla.
4. Karolo ea Phanele ea Taolo
Ka lehlakoreng le amohelang, sehlopha sa taolo keRF moduleo mamela ka sehlopha sa maqhubu a tšoanang. Ha e lemoha le ho khetholla lets'oao la FSK, e lemoha ID kapa aterese e ikhethang ea alamo, ebe e hlahisa molumo oa lehae, tlhokomeliso ea marang-rang, kapa litsebiso tse ling. Haeba monyako o bakile alamo boemong ba sensor, phanele e ka tsebisa baokameli ba thepa ka bo eona, basebetsi ba ts'ireletso, kapa esita le ts'ebeletso ea tlhahlobo ea tšohanyetso.
5. Ke Hobane'ng ha Sena se le Bohlokoa
Phokotso ea Alamo ea Bohata: Algorithm ea MCU's threshold-based algorithm e thusa ho sefa mehloli e nyane ea mosi kapa lerole.
Scalability: Lialamo tsa RF li ka hokela ho phanele e le 'ngoe ea taolo kapa li pheta-pheta tse ngata, tse nolofalletsang tšireletso e tšepahalang thepa e kholo.
Protocols Customizable: Litharollo tsa OEM/ODM li lumella bahlahisi hore ba kenye likhoutu tsa RF haeba bareki ba hloka ts'ireletso e itseng kapa litekanyetso tsa ho kopanya.
Mehopolo ea ho Qetela
Ka ho kopanya ka botlalophetoho ea data ea sensor,Li-algorithms tse thehiloeng ho MCU, lePhetiso ea RF (FSK)., lialamo tsa kajeno tsa mosi li fana ka ho lemoha ka botšepehi le khokahanyo e otlolohileng ea waelese. Hore na o molaoli oa thepa, mohokahanyi oa sistimi, kapa o labalabela ho tseba ka boenjiniere ba lisebelisoa tsa sejoale-joale tsa polokeho, ho utloisisa letoto lena la liketsahalo - ho tloha ho letšoao la analog ho isa tlhokomeliso ea dijithale - ho totobatsa kamoo lialamo tsena li entsoeng ka boqhetseke.
Lula u mametsebakeng sa ho ikakhela ka setotsoana ho thekenoloji ea RF, kopanyo ea IoT, le tharollo ea polokeho ea moloko o latelang. Bakeng sa lipotso mabapi le menyetla ea OEM/ODM, kapa ho ithuta hore na litsamaiso tsena li ka hlophisoa joang ho latela litlhoko tsa hau tse ikhethileng,ikopanye le sehlopha sa rona sa tekhenikikajeno.
