Feem ntau hais lus, a sensor yog ib lub cuab yeej uas muaj peev xwm txheeb xyuas qhov kev hloov pauv hauv ib puag ncig. Los ntawm nws tus kheej, a sensor tsis muaj txiaj ntsig, tab sis thaum peb siv nws hauv lub tshuab hluav taws xob, nws ua lub luag haujlwm tseem ceeb. A sensor Nws tuaj yeem ntsuas qhov tshwm sim ntawm lub cev (xws li qhov kub thiab txias, siab, thiab lwm yam) thiab hloov nws mus rau hauv lub teeb liab hluav taws xob.
Ib yam li ntawd, nws tau nug, IoT sensors ua haujlwm li cas?
Ib IoT system muaj sensors / khoom siv uas "hais lus" rau huab los ntawm qee yam kev sib txuas. Thaum cov ntaub ntawv nkag mus rau hauv huab, software txheej txheem nws thiab tom qab ntawd tuaj yeem txiav txim siab ua ib qho kev txiav txim, xws li xa cov lus ceeb toom lossis hloov kho lub sensors / khoom siv tsis xav tau rau tus neeg siv.
Tom qab, lo lus nug yog, dab tsi yog hom sensors? Ntau hom Sensors
- Kub Sensor.
- Sib Nqus Sensor.
- Accelerometer.
- IR Sensor (Infrared Sensor)
- Siab Sensor.
- Lub teeb Sensor.
- Ultrasonic Sensor.
- Haus luam yeeb, Roj thiab Cawv Sensor.
Ua qhov no hauv kev txiav txim siab, dab tsi yog qhov piv txwv sensor?
Sensors yog cov cuab yeej ntse uas nquag siv los kuaj xyuas thiab teb rau cov teeb liab hluav taws xob lossis kho qhov muag. A Sensor converts lub cev parameter (rau piv txwv : kub, ntshav siab, av noo, ceev, thiab lwm yam) rau hauv lub teeb liab uas yuav ntsuas tau hluav taws xob. Wb piav qhia txog piv txwv ntawm qhov kub thiab txias.
IoT puas tuaj yeem ua haujlwm yam tsis muaj Internet?
USSD muaj kev ruaj ntseg IoT kev sib txuas tsis muaj tus Internet koom nrog txhua. Tsis muaj Internet kev sib txuas yog muaj, yog li nws tsis yog ib qho kev xaiv. Ib qho array ntawm sensors muaj cov yam ntxwv tsis haum rau kev sib txuas ncaj qha rau IP-hom Internet kev sib txuas. Kev txhawj xeeb txog kev nyab xeeb ntsig txog kev nyiag ntawm Internet khoom siv.

Dab tsi yog qhov dav thawj qhov kev tshawb nrhiav thiab qhov tob thawj qhov kev tshawb fawb?
BFS sawv rau Breadth First Search. DFS sawv cev rau Kev Tshawb Nrhiav Qhov tob. 2. BFS (Breadth First Search) siv Queue cov qauv ntaub ntawv los nrhiav txoj hauv kev luv tshaj. BFS tuaj yeem siv los nrhiav ib qhov chaw luv tshaj plaws hauv cov duab tsis hnyav, vim tias hauv BFS, peb mus txog qhov kawg uas muaj qhov tsawg kawg nkaus ntawm cov npoo los ntawm qhov chaw vertex
Dab tsi yog sparse kem Dab tsi yog qhov zoo thiab qhov tsis zoo?
Koj poob 4 bytes tsis yog ib zaug ib kab; tab sis rau txhua lub cell hauv kab uas tsis yog null. Qhov zoo ntawm SPARSE kem yog: Qhov tsis zoo ntawm SPARSE kem yog: SPARSE kem tsis tuaj yeem siv rau ntawm cov ntawv, ntext, duab, timestamp, geometry, geography lossis cov neeg siv cov ntaub ntawv teev tseg
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas thiab qhov ntsuas thib ob?
Primary index: nyob rau hauv ib tug sequentially order file, qhov Performance index uas nws search key qhia cov sequential order ntawm cov ntaub ntawv. Kuj hu ua clustering index. Secondary index: ib qho Performance index uas nws qhov tseem ceeb tshawb nrhiav qhia qhov kev txiav txim sib txawv ntawm qhov kev txiav txim ntawm cov ntaub ntawv. Kuj hu ua non-clustering index
