Daim Ntawv Qhia Kom Paub: Yuav Ua Li Cas Xaiv los ntawm Ntau Hom Sensors thiab Interfacing Protocols?

Ntau hom Sensors thiab Interfacing raws tu qauv

Technology tau txuas ntxiv ntau yam ntawm tib neeg lub peev xwm, thiab lub sensor tau txuas ntxiv ntau yam ntawm tib neeg kev nkag siab. Nrog txoj kev loj hlob sai ntawm cov cuab yeej siv niaj hnub no. Muaj kev thov hnyav rau IoT, cov ntaub ntawv loj, huab xam siv tshuab thiab lwm yam. Nws yog dav siv rau kev lag luam, kev tiv thaiv kev lag luam hauv teb chaws thiab thev naus laus zis, tib neeg txoj kev ua neej thiab lwm qhov chaw.

Nkag siab Sensors thiab Lawv Lub Hom Phiaj

Nws yog hav zoov tawm muaj nrog suav tsis txheeb sensor hom. Los ntawm cov ntsuas kub qis mus rau cov txheej txheem LiDAR sophisticated, lawv txhua tus muaj lub luag haujlwm tshwj xeeb hauv peb lub ntiaj teb thev naus laus zis. Yog li, thawj kauj ruam los xaiv qhov zoo sensor yog nkag siab tias lawv ua dab tsi.

Sensors yog lub qhov muag thiab pob ntseg ntawm peb cov khoom siv, muab cov ntaub ntawv tseem ceeb los ntawm lub ntiaj teb lub cev. Lawv saib xyuas cov xwm txheej ib puag ncig, txheeb xyuas cov kev hloov pauv, thiab xa cov ntaub ntawv no mus rau lwm qhov ntawm lub cev. Dab tsi sensor koj xaiv nyob ntawm qhov koj xav ntsuas.

Hom Sensors

Ntau yam ntawm cov sensors tuaj yeem ua rau koj lub taub hau tig! Ntawm no yog ib daim duab ntawm ib co ntawm cov feem ntau sawv daws yuav:

1. Temperature Sensors: Raws li lub npe qhia, cov ntsuas kub hloov pauv no. Lawv yog cov qhob cij thiab butter ntawm HVAC systems thiab ntau yam kev lag luam.

2. Cov Sensors sib thooj: Ua ke rau cov neeg hlau thiab cov tshuab kev ruaj ntseg, cov sensors no tshawb pom qhov muaj lossis tsis muaj ib yam khoom nyob rau hauv ib qho chaw.

3. Pressure Sensors: Kev soj ntsuam huab cua los yog kua dej yog lawv cov forte. Koj yuav pom lawv hauv tsheb, cov cuab yeej kho mob, thiab kev saib xyuas huab cua.

4. Lub teeb Sensors: Cov no ntes cov teeb pom kev zoo thiab feem ntau siv hauv cov tshuab teeb pom kev zoo thiab cov koob yees duab.

Yog li rau ib txwm, Thiab cov sensors tau muab faib ua wireless sensor thiab cov pa hluav taws xob sensor.

Pa hluav taws xob sensors txuas lub cuab yeej uas tau txais cov tswv yim, muaj qhov zoo ntawm qhov raug siab, ruaj khov thiab siv tau ntau zaus yam tsis hloov pauv.

Lub wireless sensor yog cov ntaub ntawv sib txuas lus wireless uas sib koom ua ke ntawm cov haujlwm ntawm kev tau txais cov ntaub ntawv, kev tswj cov ntaub ntawv thiab kev sib txuas lus cov ntaub ntawv, muaj qhov zoo ntawm kev ua haujlwm qis, kev thauj cov ntaub ntawv wireless, tsis muaj xov, hloov tau yooj yim installation thiab debugging thiab lwm yam.

Cov txheej txheem kev sib txuas lus tau muab faib ua cov txheej txheem kev sib txuas lus wireless thiab kev sib txuas lus hauv xov tooj. Cov txheej txheem kev sib txuas lus txhais cov hom ntawv siv los ntawm chav tsev cov ntaub ntawv, cov ntaub ntawv thiab lub ntsiab lus uas cov ntaub ntawv yuav tsum muaj, hom kev sib txuas, thiab lub sij hawm thaum cov ntaub ntawv raug xa thiab tau txais, kom ntseeg tau tias kev hloov pauv ntawm cov ntaub ntawv mus rau qhov chaw txiav txim.

Hom kev sib txuas lus raws tu qauv muajRFID, infrared, ZigBee, Bluetooth, GPRS, 4G, Wifi thiab NB-IoT.Cov txheej txheem kev sib txuas lus muajMBus, USB, RS232, RS485 thiab ethernet.

Qee cov ntsiab lus ntawm Txhua Tus Txheej Txheem raws li hauv qab no:

A: Wireless Protocols

Kev sib txuas lus wireless tau dhau los ua ib feem tseem ceeb ntawm cov thev naus laus zis niaj hnub no. Los ntawm cov chaw taws teeb tswj cov khoom ua si mus rau kev siv tshuab siab heev, cov txheej txheem wireless ua lub luag haujlwm tseem ceeb. Nov yog qee qhov sib xws:

1. RFID(Xov tooj cua zaus ID): RFID yog siv rau kev sib pauv ntaub ntawv tsis sib cuag, feem ntau hauv kev tswj xyuas kev nkag mus thiab cov cuab yeej cuab tam.

2. Infrared:Kev sib txuas lus infrared yog siv rau hauv cov ntawv thov luv luv, xws li cov chaw taws teeb hauv TV thiab cov ntaub ntawv luv luv ntawm cov khoom siv.

3. ZigBee:ZigBee yog lub zog qis, cov ntaub ntawv qis-tus nqi wireless feem ntau siv hauv chaw tsim khoom, tsev ntse, thiab cov chaw taws teeb tswj.

4. Bluetooth:Tej zaum koj yuav paub qhov no! Bluetooth yog siv rau luv luv, taw tes rau-taw tes, thiab taw tes-to-multipoint kev sib txuas lus. Nws zoo meej rau kev sib txuas cov khoom siv xws li cov keyboards, nas, thiab lub mloog pob ntseg.

5. GPRS(General Packet Radio Service): GPRS yog siv hauv kev sib txuas lus hauv xov tooj ntawm tes rau kev nkag mus rau hauv internet, xov tooj cua sib tham, thiab cov kev pab cuam raws li qhov chaw.

6.4g: ib.Lub cim thib plaub ntawm kev siv xov tooj ntawm tes, 4G muab mobile ultra-broadband internet nkag rau hauv xov tooj ntawm tes, laptops, thiab lwm yam khoom siv mobile.

7. Wifi:Wifi yog wireless networking raws tu qauv uas tso cai rau cov khoom siv sib txuas lus yam tsis muaj kev sib txuas ncaj qha. Nws tau dav siv hauv tsev network, chaw ua haujlwm tes hauj lwm, thiab pej xeem hotspots.

8. NB-IoT(Narrowband Internet of Things): NB-IoT yog lub zog qis qis hauv cheeb tsam network raws tu qauv tsim los txuas cov khoom siv thoob plaws qhov ntev hauv thaj chaw nyuaj. Nws yog qhov zoo tagnrho rau IoT daim ntawv thov.

B: Wired Protocols

Txawm tias nyob rau hauv peb lub ntiaj teb wireless, wired raws tu qauv tseem muaj lub luag haujlwm tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv kev lag luam thiab kev siv cov ntaub ntawv siab.

1. MBus (Meter-Bus):MBus yog tus qauv European rau kev nyeem tej thaj chaw deb ntawm cov ntsuas kub thiab lwm yam ntsuas ntsuas.

2. USB (Universal Serial Bus):USB yog siv rau kev sib txuas, kev sib txuas lus, thiab lub zog ntawm cov khoos phis tawj thiab lawv cov khoom siv peripheral.

3. RS232:Qhov no yog tus qauv rau kev sib txuas lus sib txuas ntawm cov ntaub ntawv. Nws yog ib txwm siv hauv computer serial ports.

4. RS485:Zoo ib yam li RS232, RS485 txhawb nqa ntau ntawm ib lub network thiab ntev cable ntev. Nws yog siv nyob rau hauv industrial tswj systems thiab lub tsev automation.

5. Ethernet:Ethernet yog dav siv hauv cheeb tsam hauv cheeb tsam network (LANs). Nws muab kev kub ceev thiab txhim khu kev qha kev sib txuas lus ntawm cov khoom siv.

Xaiv cov txheej txheem tsim nyog yuav nyob ntawm qhov kev thov thiab ib puag ncig. Ib txwm xav txog yam xws li ntau yam, kev siv hluav taws xob, cov ntaub ntawv tus nqi, thiab hom khoom siv txuas nrog thaum koj xaiv.

Xyoo 1983, raws li RS-422 Industrial Bus standard, Electronic Industry Association tsim thiab muab RS-485 industrial Bus standard. Lub tsheb npav RS-485-tus qauv qhia cov qauv rau cov khoom siv hluav taws xob ntawm cov tsheb npav sib cuam tshuam uas tau hais tseg rau ob lub ntsiab lus hauv lub xeev: Cov theem zoo yog nyob nruab nrab ntawm +2V ~ + 6V, qhia txog lub xeev cov laj thawj; Qib tsis zoo ntawm -2V thiab -6V qhia txog lwm lub xeev kev xav. Cov teeb liab digital txais kev sib kis sib txawv, uas tuaj yeem txo qhov cuam tshuam ntawm lub suab nrov.

Nws tuaj yeem txhawb nqa ntau qhov chaw sib txuas, kev sib txuas lus nyob deb thiab siab rhiab heev ntawm cov ntaub ntawv tau txais. Hauv kev sib txuas lus hauv kev lag luam, RS - 485 tsheb npav feem ntau yog siv dav dav thiab sab nraud cov ntaub ntawv xa mus thiab cov ntaub ntawv sib pauv, txhua yam ntawm cov cuab yeej siv tau zoo rau lub suab nrov muaj peev xwm, cov ntaub ntawv hloov pauv tau zoo thiab kev ntseeg tau zoo ntawm cov ntaub ntawv xa mus thiab kev sib txuas lus cable ntev yog unmatched los ntawm lwm yam kev lag luam kev sib txuas lus qauv.Yog li ntawd, RS-485 tau dav siv nyob rau hauv ntau lub teb.

Kev sib txuas lus raws tu qauv ntawm HENGKOkub thiab humidity sensorthiabgas sensoryog RS-485. Nyob rau hauv qhov kub thiab av noo thiab roj ntes, RS-485 tsheb npav tuaj yeem xa cov ntaub ntawv thiab pauv cov ntaub ntawv ncaj qha nrog lub sensor kom paub meej cov ntaub ntawv tam sim ntawd teb thiab raug.

Tsis tas li ntawd, lubgas sensor sojntsuamraws li lub ntsuas ntsuas muaj txiaj ntsig zoo ntawm qhov ntsuas ntsuas qhov tseeb. Raws li qhov sib txawv ntsuas ib puag ncig ntawm lub sensor, nws yog ib qho tseem ceeb heev uas yuav tau xaiv qhov kev sojntsuam vaj tse. Xws li stainless hlau sojntsuam vaj tsev muaj qhov zoo ntawm qhov kub thiab txias,anti-corrosion, tsis muaj dej, tshem tawm plua plav, muaj nyob rau hauv qhov kub thiab txias, plua plav loj thiab lwm qhov chaw hnyav.
