Kev siv tshuab tau nthuav dav ntau yam peev xwm ntawm tib neeg, thiab lub sensor tau nthuav dav ntau yam kev pom ntawm tib neeg. Nrog rau kev txhim kho sai ntawm cov thev naus laus zis niaj hnub no. Muaj kev thov ntau rau IoT, cov ntaub ntawv loj, kev siv tshuab huab thiab lwm yam. Nws tau siv dav rau kev lag luam, kev tiv thaiv teb chaws, kev ua neej nyob thiab lwm qhov chaw.
To taub Cov Sensors thiab Lawv Lub Hom Phiaj
Nws yog ib lub hav zoov uas muaj ntau hom sensors. Txij li cov sensors kub me me mus rau cov tshuab LiDAR zoo heev, lawv txhua tus muaj lub luag haujlwm tshwj xeeb hauv peb lub ntiaj teb uas tsav los ntawm thev naus laus zis. Yog li, thawj kauj ruam los xaiv cov sensor zoo yog kev nkag siab txog lawv ua dab tsi.
Cov sensors yog lub qhov muag thiab pob ntseg ntawm peb cov khoom siv, muab cov ntaub ntawv tseem ceeb los ntawm lub ntiaj teb. Lawv saib xyuas cov yam ntxwv ib puag ncig, ntes cov kev hloov pauv, thiab xa cov ntaub ntawv no mus rau lwm qhov ntawm lub system. Koj xaiv lub sensor twg feem ntau nyob ntawm seb koj xav ntsuas dab tsi.
Hom Sensors
Qhov ntau yam ntawm cov sensors ua rau koj lub taub hau tig! Nov yog ib daim duab ntawm qee qhov feem ntau pom:
1. Cov Khoom Siv Ntsuas Kub: Raws li lub npe qhia, cov no taug qab qhov kub thiab txias hloov pauv. Lawv yog cov khoom siv tseem ceeb ntawm HVAC systems thiab ntau yam txheej txheem kev lag luam.
2. Cov Sensors Proximity: Siv tau rau cov neeg hlau thiab cov tshuab kev ruaj ntseg, cov sensors no ntes tau qhov muaj lossis tsis muaj ib yam khoom hauv ib qho chaw.
3. Cov Khoom Siv Ntsuas Siab: Kev saib xyuas qhov siab ntawm huab cua lossis kua dej yog lawv lub zog. Koj yuav pom lawv hauv cov tsheb, cov khoom siv kho mob, thiab cov tshuab saib xyuas huab cua.
4. Cov Sensors Teeb: Cov no ntes tau qib teeb thiab feem ntau siv rau hauv cov tshuab teeb pom kev zoo thiab cov koob yees duab.
Yog li ntawd, rau feem ntau, Thiab cov sensors raug muab faib ua lub wireless sensor thiab cov sensor wired ib txwm muaj.
Cov cuab yeej ntsuas hluav taws xob ib txwm txuas cov khoom siv uas tau txais cov tswv yim, muaj qhov zoo ntawm qhov raug siab, ruaj khov thiab tuaj yeem siv ntau zaus yam tsis tau hloov.
Lub wireless sensor yog lub wireless data communication collector uas koom ua ke cov haujlwm ntawm kev nrhiav cov ntaub ntawv, kev tswj cov ntaub ntawv thiab kev sib txuas lus cov ntaub ntawv, muaj qhov zoo ntawm kev ua haujlwm tsawg zog, kev thauj cov ntaub ntawv wireless, tsis muaj xov hlau, kev teeb tsa yooj yim thiab kev debugging thiab lwm yam.
Cov txheej txheem sib txuas lus muaj ob hom: wireless communication protocols thiab wired communication protocols. Cov txheej txheem sib txuas lus txhais cov hom ntawv uas siv los ntawm cov ntaub ntawv, cov ntaub ntawv thiab lub ntsiab lus uas cov ntaub ntawv yuav tsum muaj, hom kev sib txuas, thiab lub sijhawm xa thiab txais cov ntaub ntawv, kom ntseeg tau tias kev xa cov ntaub ntawv mus rau qhov chaw tau teem tseg zoo.
Cov hom kev sib txuas lus muajRFID, infrared, ZigBee, Bluetooth, GPRS, 4G, Wifi thiab NB-IoT.Cov txheej txheem sib txuas lus muajMBus, USB, RS232, RS485 thiab ethernet.
Qee cov ntsiab lus ntawm txhua cov txheej txheem raws li nram no:
A: Cov Txheej Txheem Wireless
Kev sib txuas lus wireless tau dhau los ua ib feem tseem ceeb ntawm thev naus laus zis niaj hnub no. Txij li cov khoom ua si tswj chaw taws teeb mus rau cov tshuab ua haujlwm siab heev, cov txheej txheem wireless ua lub luag haujlwm tseem ceeb. Nov yog qee qhov feem ntau:
1. RFID(Kev Txheeb Xyuas Zaus Xov Tooj Cua): RFID siv rau kev sib pauv cov ntaub ntawv tsis tas kov, feem ntau yog siv rau hauv kev tswj kev nkag thiab cov txheej txheem taug qab cov khoom muaj nqis.
2. Infrared:Kev sib txuas lus infrared yog siv rau hauv cov ntawv thov luv luv, xws li cov chaw taws teeb tswj TV thiab kev xa cov ntaub ntawv luv luv ntawm cov khoom siv.
3. ZigBee:ZigBee yog lub network wireless uas siv hluav taws xob tsawg, cov ntaub ntawv tsawg uas feem ntau siv rau hauv cov chaw lag luam, cov tsev ntse, thiab cov chaw tswj chaw taws teeb.
4. Bluetooth:Tej zaum koj paub qhov no lawm! Bluetooth siv rau kev sib txuas lus luv luv, taw tes rau taw tes, thiab taw tes rau ntau lub ntsiab lus. Nws zoo meej rau kev txuas cov khoom siv xws li keyboards, nas, thiab lub mloog pob ntseg.
5. GPRS(Kev Pabcuam Xov Tooj Cua Dav Dav): GPRS siv rau hauv kev sib txuas lus ntawm tes rau kev nkag mus rau hauv internet, kev xa xov multimedia, thiab cov kev pabcuam raws li qhov chaw.
6. 4G:Lub tiam plaub ntawm kev siv thev naus laus zis cellular, 4G muab kev nkag mus rau hauv internet ultra-broadband rau cov xov tooj ntawm tes, laptops, thiab lwm yam khoom siv mobile.
7. Wifi:Wifi yog ib qho wireless networking protocol uas tso cai rau cov khoom siv sib txuas lus yam tsis tas yuav muaj kev sib txuas cable ncaj qha. Nws siv dav hauv cov network hauv tsev, cov network hauv chaw ua haujlwm, thiab cov hotspots pej xeem.
8. NB-IoT(Narrowband Internet of Things): NB-IoT yog ib qho protocol network dav dav uas siv hluav taws xob tsawg uas tsim los txuas cov khoom siv hla kev deb hauv thaj chaw nyuaj mus txog. Nws zoo tagnrho rau cov ntawv thov IoT.
B: Cov Txheej Txheem Txuas Nrog Xov Tooj
Txawm tias nyob hauv peb lub ntiaj teb wireless, cov txheej txheem wired tseem muaj lub luag haujlwm tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv kev lag luam thiab cov ntawv thov siab.
1. MBus (Meter-Bus):MBus yog tus qauv European rau kev nyeem cov ntsuas kub thiab lwm yam ntsuas kev siv hluav taws xob.
2. USB (Universal Serial Bus):USB yog siv rau kev sib txuas, kev sib txuas lus, thiab kev muab hluav taws xob ntawm cov khoos phis tawj thiab lawv cov khoom siv peripheral.
3. RS232:Qhov no yog tus qauv rau kev sib txuas lus ntawm cov ntaub ntawv. Nws yog ib txwm siv rau hauv cov chaw nres nkoj serial ntawm lub computer.
4. RS485:Ib yam li RS232, RS485 txhawb nqa ntau lub nodes hauv ib lub network thiab ntev dua cov cable. Nws siv rau hauv cov tshuab tswj kev lag luam thiab kev ua haujlwm hauv tsev.
5. Ethernet:Ethernet siv dav hauv cov tes hauj lwm hauv zos (LANs). Nws muab kev sib txuas lus ceev ceev thiab txhim khu kev qha ntawm cov khoom siv.
Kev xaiv cov txheej txheem tsim nyog yuav nyob ntawm daim ntawv thov thiab ib puag ncig. Ib txwm xav txog cov yam xws li qhov deb, kev siv hluav taws xob, tus nqi ntawm cov ntaub ntawv, thiab hom khoom siv txuas nrog thaum koj ua qhov kev xaiv.
Xyoo 1983, raws li tus qauv RS-422 Industrial Bus, Lub Koom Haum Kev Lag Luam Hluav Taws Xob tau tsim thiab tshaj tawm tus qauv RS-485 industrial Bus. Tus qauv RS-485 bus qhia txog cov qauv rau cov khoom siv hluav taws xob ntawm cov interfaces tsheb npav uas tau txhais rau ob lub xeev logic: Qib zoo yog ntawm + 2V ~ + 6V, qhia txog lub xeev logic; Qib tsis zoo ntawm -2V thiab -6V qhia txog lwm lub xeev logic. Lub teeb liab digital siv hom kev sib kis sib txawv, uas tuaj yeem txo qhov cuam tshuam ntawm lub teeb liab suab nrov.
Nws tuaj yeem txhawb nqa ntau lub sub-nodes, kev sib txuas lus deb thiab kev nkag siab siab ntawm kev txais cov ntaub ntawv. Hauv kev sib txuas lus hauv kev lag luam, RS-485 lub tsheb npav feem ntau yog siv rau kev xa cov ntaub ntawv dav dav thiab sab nraud thiab kev sib pauv cov ntaub ntawv, txhua yam khoom siv hauv kev lag luam muaj txiaj ntsig zoo rau kev txo suab nrov, kev hloov pauv cov ntaub ntawv zoo thiab kev ntseeg siab ntawm kev xa cov ntaub ntawv thiab qhov ntev ntawm kev sib txuas lus cable tsis sib piv los ntawm lwm cov qauv kev sib txuas lus hauv kev lag luam. Yog li ntawd, RS-485 tau siv dav hauv ntau qhov chaw.
Cov txheej txheem sib txuas lus ntawm HENGKOntsuas kub thiab av noothiablub ntsuas rojyog RS-485. Hauv qhov kub thiab av noo thiab roj ntes, RS-485 lub tsheb npav tuaj yeem xa cov ntaub ntawv thiab pauv cov ntaub ntawv ncaj qha nrog lub sensor kom ntseeg tau tias cov ntaub ntawv teb tam sim ntawd thiab raug.
Dhau li ntawm qhov ntawd, qhovroj sensor soj ntsuamRaws li ib qho khoom ntsuas muaj qhov cuam tshuam loj rau qhov tseeb ntawm qhov ntsuas ntawm lub sensor. Raws li qhov chaw ntsuas sib txawv ntawm lub sensor, nws yog ib qho tseem ceeb heev uas yuav tsum xaiv lub tsev soj ntsuam. Xws li lub tsev soj ntsuam stainless hlau muaj qhov zoo ntawm kev tiv taus kub siab,tiv thaiv xeb, tsis muaj dej, tshem tawm plua plav, muaj rau qhov kub thiab txias thiab av noo, plua plav loj thiab lwm yam chaw ib puag ncig hnyav.
Nrog rau kev txhim kho thev naus laus zis tas li, qhov xav tau ntawm ntau yam sensor muaj ntau dua thiab ntau dua.
