Kev siv lub ntsuas ntsuas ntse
Cov txiaj ntsig ntse ntse
Cov ntsuas no pab peb txhim kho koj cov kev pabcuam thiab muab cov cuab yeej muaj zog rau koj los tswj koj lub zog siv, nrog rau koj cov nqi.
SMUD cov chaw nyob thiab kev lag luam ntse ntsuas yog ib feem loj ntawm "smart grid," uas xa hluav taws xob siv cov thev naus laus zis digital. Qhov no txuag hluav taws xob, txo cov nqi thiab nce kev ntseeg siab.
Los ntawm kev txhim kho cov ntsuas ntse hauv koj lub tsev lossis kev lag luam, peb yuav muaj cov thev naus laus zis thev naus laus zis los txhim kho koj cov kev pabcuam thiab muab cov cuab yeej muaj zog rau koj los saib xyuas - thiab kho - koj lub zog siv thaum koj nkag rau hauv Kuv Tus Account.
Koj tseem tuaj yeem sau npe rau cov ntawv sau thiab email ceeb toom kom taug qab nrog koj lub zog siv thiab koj cov peev nyiaj.
Tsis xav tau smart meter? Kawm paub yuav ua li cas xaiv.
Kev pabcuam hluav taws xob puas tuaj yeem txuas lossis txiav tawm ntawm qhov chaw deb?
Yog lawm. Piv txwv li, yog tias koj tsiv mus, koj yuav tsis tas tos rau tus kws tshaj lij kev pabcuam, tawm koj lub rooj vag qhib lossis txhawj xeeb txog koj cov tsiaj.
Kuv yuav rov pib dua kuv lub ntsuas li cas yog tias kuv qhov kev pabcuam raug txiav lawm?
Thaum koj tau them koj cov nyiaj them poob haujlwm, thov tos ib teev thiab ua raws li cov lus qhia hauv qab no kom rov pib dua koj lub ntsuas. Peb xav kom koj rov txuas dua kev nyab xeeb. Yog tias cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob tau qhib thaum koj lub zog tawm mus, nws tuaj yeem tsim teeb meem thaum koj lub zog rov qab los.
- Thov xyuas kom meej tias tag nrho cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob raug kaw tsuas yog ib lub teeb, uas yuav qhia tau tias thaum muaj kev pab cuam rov qab los.
- Mus rau lub 'meter' nyob sab nraum qhov chaw nyob. Lub ntsuas yuav nyeem "ARM" yog tias nws yuav tsum tau rov pib dua.
- Nias lub khawm dub nyob rau pem hauv ntej ntawm lub 'meter' kom txog thaum nws nyem.
Yog tias koj nrhiav tsis tau koj lub 'meter' thiab koj nyob hauv tsev, lub 'meter' nyob ntawm phab ntsa sab nraum koj lub tsev. Yog tias koj nyob hauv ib chav tsev, thov hu rau koj tus tswv tsev lossis Lub Tuam Txhab Tswj Xyuas Khoom. Yog tias koj tseem xav tau kev pab, thov hu rau Cov Neeg Siv Khoom.
Lub ntsuas ntsuas ntse puas cuam tshuam nrog kuv lub tsev hluav taws xob?
Tsis yog. Cov ntsuas ntsuas ntse yog tsim los kom tsis txhob cuam tshuam nrog koj cov khoom siv hluav taws xob hauv tsev.
Kuv cov ntaub ntawv siv zog puas yuav tsis pub leej twg paub thiab nyab xeeb?
Yog lawm. Koj cov ntaub ntawv siv hluav taws xob yuav raug xa mus rau cov servers ruaj ntseg rau SMUD. Lub tuam txhab uas muab SMUD lub wireless network siv tib hom kev ruaj ntseg raws li Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv thiab kev lag luam hauv online.
Lub ntsuas ntsuas ntse pab tiv thaiv ib puag ncig li cas?
Hauv ntau qhov chaw tseem ceeb:
- Los ntawm tsis xav tau ib lub ntsuas ntsuas los mus xyuas koj lub tsev txhua lub hlis, koj lub ntsuas ntsuas ntse yuav txo cov pa phem, txo qis kev siv roj thiab peb yuav muaj tsheb tsawg dua ntawm txoj kev.
- Koj yuav muaj peev xwm txiav txim siab txog koj lub zog siv, uas tuaj yeem txo qhov kev thov rau hluav taws xob.
Kuv puas tuaj yeem nyeem kuv tus kheej lub ntsuas ntsuas ntse?
Yog lawm, kawm seb nws yooj yim npaum li cas los nyeem koj lub ntsuas.
Kuv puas tuaj yeem xaiv tsis muaj lub ntsuas ntsuas ntse?
Yog, Nrhiav cov ntaub ntawv ntxiv txog peb txoj cai xaiv tawm thiab nqi.
Electromagnetic Fields thiab Xov tooj cua zaus
EMF yog dab tsi?
Lub sij hawm EMF (electromagnetic teb los yog hluav taws xob thiab magnetic teb) yog siv rau tsawg zaus, alternating los yog ncaj qha tam sim no, sib nqus los yog hluav taws xob teb. Ib qho chaw electromagnetic (tseem EMF lossis EM field) yog lub cev ua haujlwm uas tsim los ntawm kev txav cov khoom siv hluav taws xob.
EMF tshwm sim qhov twg?
EMF's nyob txhua qhov chaw hauv peb lub ntiaj teb niaj hnub no. Nov yog qee qhov piv txwv
:
- Lawv ib txwm tshwm sim los ntawm tiam, kev sib kis thiab kev faib hluav taws xob
hauv cov tsev - Cov hauv paus muaj xws li cov kab hluav taws xob, cov kab hluav taws xob hauv tsev thiab cov khoom siv
- Tsawg zaus tshuab yog siv los xa hluav taws xob rau hauv peb lub tsev
- Cov hluav taws xob hluav taws xob yog tsim los ntawm qhov hluav taws xob tam sim no nyob rau hauv lub kaw lus, tsis hais hauv cov xov hluav taws xob lossis cov hlua hluav taws xob
Dab tsi yog qhov txawv ntawm EMF thiab xov tooj cua zaus (RF)?
Ntawm ntau zaus ntau dua, EMF's tau piav qhia tias "xov tooj cua zaus" lossis RF.
- Xov tooj cua zaus yog siv rau kev xa xov tooj cua, suav nrog kev sib txuas lus wireless
- Txhua zaus ntawm hluav taws xob hluav taws xob hluav taws xob nruab nrab ntawm 1kHz thiab 300 GHz, nrog rau cov xov tooj cua thiab TV, yog RF.
- RF yog siv los xa lub zog thiab cov teeb liab los ntawm huab cua raws li kev xa xov wireless
- RF yog siv rau AM thiab FM satellite xov tooj cua, TV, radar, xov tooj ntawm tes, xov tooj ntawm tes, cordless xov tooj, Bluetooth, wireless computer thiab cov ntaub ntawv xa mus (WLAN, WI-FI, WiMAX) tes hauj lwm.
Puas smart meters tsim RF teb?
Yog. Smart meters emit ib watt. Hauv kev sib piv, xov tooj ntawm tes thiab wireless routers tawm ntawm 1-2 watts. Koj lub ntsuas hluav taws xob ntse xa xov tooj cua ib zaug ib zaug hauv plaub teev, nrog rau txhua qhov sib kis tau ntev 5/1000ths ntawm ib thib ob.
Cov ntsuas ntse tsim lub network txhawm rau ua haujlwm. Lawv tuaj yeem ua "repeater" (ib feem ntawm kev sib txuas lus) rau lwm qhov chaw nyob ze. Lawv tuaj yeem sib txuas lus txhua hnub los tshaj tawm cov xwm txheej xws li:
- Kev tawg
- Voltage fluctuation
- Kev ceeb toom txog tampering thiab fais fab tub sab
- On-demand nyeem ntawm koj qhov kev thov
- Cov kev sib txuas lus no tsis tshua muaj - tshwm sim nyob rau nruab nrab 60 vib nas this rau txhua 24 teev
Hauv 2012, peb tau ua cov ncauj lus kom ntxaws txog kev sib kis ntau zaus thiab qhov hnyav nruab nrab "ntawm huab cua" lub sijhawm hla lub ntsuas ntsuas ntse.
Nov yog cov txiaj ntsig:
| Electric system lus hom | Kev xa tawm zaus ib 24-teev sijhawm: Nruab nrab | Kev xa tawm zaus ib 24-teev sijhawm: Ntau tshaj (99.9th feem pua) |
| Meter nyeem cov ntaub ntawv | 6 | 6 |
| Network tswj | 15 | 30 |
| Sijhawm sync | 360 | 360 |
| Mesh network lus tswj | 13,000 | 240,000 |
| Weighted nruab nrab lub luag hauj lwm voj voog | 61.4 feeb | 1,262 feeb |
Cov txiaj ntsig ntawm txoj kev tshawb fawb no lees paub tias, qhov nruab nrab, meters sib txuas lus kwv yees li 60 vib nas this nyob rau txhua txhua 24teev. Qhov "lub voj voog ua haujlwm" no tsawg dua li lwm yam khoom siv xws li xov tooj ntawm tes, wireless routers, thiab cov xov tooj tsis muaj zog.
Kev sib piv ntawm RF lub zog ceev hauv ib puag ncig txhua hnub
| Ntaus ntawv | Relative zog ceev nyob rau hauv microwatts ib square centimeter |
| FM xov tooj cua lossis TV tshaj tawm xov xwm | 0.005 microwatts |
| Smart meter ntaus ntawv ntawm 10 ft. | 0.1 microwatts |
| Cyber cafe (wi-fi) | 10-20 microwatts |
| Lub laptop computer | 10-20 microwatts |
| Xov tooj ntawm tes tuav rau pob ntseg | 30-10,000 microwatts |
| Walkie-talkie ntawm taub hau | 500-42,000 microwatts |
| Microwave qhov cub, 2 ntiv tes los ntawm qhov rooj | 5,000 microwatts |

Puas yog smart meter RF teb muaj kev nyab xeeb?
Yog lawm. Cov yam tseem ceeb rau kev pheej hmoo raug kis yog lub zog thiab zaus ntawm qhov emission thiab nyob deb ntawm tus neeg. Cov ntsuas ntse ntse tso tawm tsuas yog kwv yees li 1 watt, thiab thaum nruab, tsis muaj lub tshuab xa hluav taws xob nyob hauv koj lub tsev. Cov xov tooj ntawm tes tau suav tias yog qhov pheej hmoo dua vim lawv tau tuav koj lub taub hau. Peb cov ntsuas ntsuas ntse ua tau raws li FCC kuaj thiab ntawv pov thawj. Tsis tas li ntawd, peb tau ua cov kauj ruam ntxiv ntawm kev sim RF nruj thaum lub sij hawm pib tawm. Txawm tias thaum sib koom ua ke xws li hauv cov chav tsev, lawv cov RF emissions tsawg thaum piv rau FCC cov lus qhia raug.
Puas yuav ntse ntsuas RF teb cuam tshuam nrog kuv cov khoom siv hluav taws xob lossis khoom siv kho mob?
Cov ntsuas ntse uas peb siv tau raug lees paub los ntawm FCC thiab yuav tsum tsis txhob cuam tshuam nrog cov khoom siv hauv lossis ib puag ncig koj lub tsev.
