Sei RF 433/868 Smoke Alarms Inobatanidza neKudzora Panel?
Iwe urikuda kuziva here kuti isina waya yeRF chiutsi alarm inonyatsoona sei utsi uye inozivisa yepakati pani kana yekutarisa system? Muchinyorwa chino, tichaparura zvikamu zvakakosha zveaRF aramu yehutsi, tichitarisa kuti seiMCU (microcontroller) inoshandura zviratidzo zveanalogmudhijitari data, inoshandisa chikumbaridzo-yakavakirwa algorithm, uye ipapo siginecha yedhijitari inoshandurwa kuita 433 kana 868 RF siginecha kuburikidza neFSK gadziriso michina uye inotumirwa kune control panel inobatanidza iyo yakafanana RF module.
1. Kubva pakuona Smoke kusvika kuData Shanduko
Pamwoyo weRF yehutsi alarm panephotoelectric sensoriyo inopindirana nekuvapo kwezvimedu zveutsi. Iyo sensor inoburitsa ananalog voltagezvakaenzana nekuwanda kwehutsi. AnMCUmukati me alarm inoshandisa yayoADC (Analog-to-Digital Converter)kushandura iyi analog voltage kuita digital values. Nekuenderera mberi nekuenzanisa kuverenga uku, iyo MCU inogadzira chaiyo-nguva data rwizi rwemazinga ehutsi.
2. MCU Threshold Algorithm
Panzvimbo pekutumira sensor yega yega kuverenga kune iyo RF transmitter, iyo MCU inomhanyaalgorithmkuona kana mwero weutsi uchidarika mwero wakagara waiswa. Kana iyo yekumisikidza iri pasi peiyi muganhu, alarm inoramba yakanyarara kudzivirira manyepo kana kunetsa maaramu. Kamwe iyokuverenga kwedhijitari kunopfuuraiyo chikumbaridzo, iyo MCU inoiisa sengozi inogona moto, zvichikonzera danho rinotevera mukuita.
Mapoinzi Akakosha eiyo algorithm
Kusefa Noise: Iyo MCU inofuratira mapikisi enguva pfupi kana kuchinjika kudiki kuderedza maaramu enhema.
Avhareji uye Nguva Yekutarisa: Madhizaini mazhinji anosanganisira hwindo renguva (semuenzaniso, kuverenga pamusoro penguva yakati) kuratidza chiutsi chinoramba chiripo.
Threshold Comparison: Kana kuverenga kweavhareji kana peak kukaramba kuri pamusoro pechikumbaridzo chakaiswa, alarm logic inotanga yambiro.
3. RF Transmission kuburikidza neFSK
Kana iyo MCU yaona kuti alarm mamiriro asangana, inotumira iyo yambiro chiratidzo kuburikidzaSPIkana imwe nzira yekukurukurirana kune anRF transceiver chip. Chip ichi chinoshandisaFSK (Frequency Shift Keying)modulation ORBvunza (Amplitude-Shift Keying)kukodha data yearamu yedhijitari pane imwe frequency (semuenzaniso, 433MHz kana 868MHz). Chiratidzo chearamu chinobva chafambiswa zvisina waya kune inotambira unit-kazhinji acontrol panelkanamonitoring system-painopatsanurwa uye inoratidzwa seyambiro yemoto.
Sei FSK Modulation?
Stable Transmission: Shifting frequency ye0/1 bits inogona kuderedza kupindira mune dzimwe nharaunda.
Flexible Protocols: Yakasiyana data-encoding zvirongwa zvinogona kuiswa pamusoro peFSK kuchengetedza uye kuenderana.
Low Power: Inokodzera mabhatiri-anoshanda zvishandiso, kuenzanisa renji uye mashandisiro emagetsi.
4. Basa reKudzora Panel
Padivi rekugamuchira, iyo control panel'sRF moduleinoteerera pane imwechete frequency band. Kana yaona nekudhidha chiratidzo cheFSK, inoona ID yakasarudzika yearamu kana kero, yobva yatanga bhaza remunharaunda, yambiro yetiweki, kana zvimwe zviziviso. Kana chikumbaridzo chakonzera alarm padanho re sensor, iyo pani inogona kuzivisa otomatiki maneja ezvivakwa, vashandi vekuchengetedza, kana kunyangwe basa rekutarisa emergency.
5. Nei Izvi Zvichikosha
Nhema Alarm Kuderedzwa: Iyo MCU's pachikumbaridzo-yakavakirwa algorithm inobatsira kusefa kunze madiki eutsi masosi kana guruva.
Scalability: RF maaramu anogona kubatanidza kune imwe control panel kana akawanda anodzokorora, achigonesa kufukidzwa kwakavimbika muzvivakwa zvakakura.
Customizable Protocols: OEM/ODM mhinduro dzinorega vagadziri vaime evaridzi RF makodhi kana vatengi vachida chaiyo chengetedzo kana yekubatanidza zviyero.
Pfungwa dzekupedzisira
Nokubatanidza pasina musonosensor data shanduko,MCU-yakavakirwa pachikumbaridzo algorithms,uyeRF (FSK) kutapurirana, maaramu ehutsi emazuva ano anopa zvose zvinovimbika kuona uye zvakananga wireless connectivity. Kunyangwe iwe uri maneja wezvivakwa, munobatanidza sisitimu, kana kungoda kuziva nezveinjiniya iri kuseri kwemidziyo yekuchengetedza yemazuva ano, kunzwisisa iyi nhevedzano yezviitiko-kubva kuchiratidzo cheanalogi kusvika kuchenjedzo yedhijitari-inoratidza kuti maaramu aya akanyatsogadzirwa sei.
Ramba wakatarisayekuwedzera kudzika muRF tekinoroji, IoT kubatanidzwa, uye inotevera-chizvarwa kuchengetedza mhinduro. Pamibvunzo nezve OEM/ODM zvingaitika, kana kudzidza kuti masisitimu aya anogona kugadzirwa sei kune zvaunoda chaizvo,bata timu yedu yehunyanzvinhasi.
