Intelligentne linn on p\u00e4rast industrialiseerimist, informatiseerimist ja elektrifitseerimist neljas laine. Intelligentse linna ehitamine on globaalse linnaarengu eesliinitrend. T\u00e4nap\u00e4eval on paljud linnade vihmavee \u00e4ravoolutorud sageli ummistunud, mis m\u00f5jutab t\u00f5siselt drenaa\u017ei, mille tulemuseks on sagedane vee kogunemine teedele, mis omakorda m\u00f5jutab t\u00f5siselt inimeste elu ja reisimist. Lisaks on viimastel aastatel aeg-ajalt kaevude katet varastatud ja kahjustatud, mist\u00f5ttu jalak\u00e4ijad kukuvad m\u00f5nikord kanalisatsiooni. Liiga suur liiklus m\u00f5jutab samuti liiklusolukorda ja inimeste reisimist. Seet\u00f5ttu on v\u00e4ga oluline s\u00fcstemaatiliselt hallata k\u00f5iki munitsipaalprobleemide aspekte. Samal ajal pakub tehnoloogia areng koos traadita andurite intelligentse sensoritehnoloogia arenguga, NB-IOT mobiilsidetehnoloogia kiire arengu ja kasutuselev\u00f5tuga ning lairiba interneti kiire populaarsusega ka tugeva tehnilise aluse \u201eintelligentse linna munitsipaaljuhtimise\u201c ehitamiseks.<\/p>\n\n\n\n

1 S\u00fcsteemi funktsioon<\/p>\n\n\n\n

Me ehitame linnajuhtidele intelligentse munitsipaalhalduse platvormi, mis suudab samaaegselt kaugjuhtimise teel j\u00e4lgida puurkaevude kaante olekut, liiklusvoogu, torujuhtmete ummistusi ja muud teavet, andes probleemide ilmnemisel \u00f5igeaegselt m\u00e4rku ja pakkudes t\u00f5husamaid lahendusi. Toode suudab k\u00f5iki toiminguid visuaalselt teostada.<\/p>\n\n\n\n

2 p\u00f5hilist disainiideed<\/p>\n\n\n\n

2.1 Veevoolu seisundi j\u00e4lgimine<\/p>\n\n\n\n

Iga s\u00f5lm kasutab veetaseme k\u00f5rguse tuvastamiseks ultraheli moodulit ja v\u00f5rdleb k\u00fclgnevate s\u00f5lmede veetaseme k\u00f5rgust, et hinnata, kas ummistus on tekkinud (kui k\u00fclgnevate s\u00f5lmede veetaseme erinevus on suur, v\u00f5ib eeldada, et kahe s\u00f5lme vaheline drenaa\u017eitorustik on ummistunud, ja ummistuse raskusastet saab ligikaudselt hinnata k\u00f5rguse erinevuse j\u00e4rgi). Ummistuse tuvastamise skemaatiline diagramm on n\u00e4idatud joonisel 1.<\/p>\n\n\n\n

Veetaseme k\u00f5rgusk\u00f5vera moodustamiseks kogutakse igal ajahetkel veetaseme kohta k\u00e4ivat teavet. Kui veetaseme k\u00f5rgus t\u00f5useb liiga kiiresti, k\u00e4ivitub h\u00e4ire.<\/p>\n\n\n\n

Moodul paigutatakse truubi \u00fclaossa kaevu l\u00e4hedale, et v\u00e4listada ebatasase pinnase m\u00f5ju. Ultraheli kauguse m\u00f5\u00f5tmise p\u00f5him\u00f5te on m\u00f5\u00f5ta aega, mis kulub helilaine peegeldumiseks takistuselt p\u00e4rast selle v\u00e4ljalaskmist, tuginedes ultrahelilaine teadaolevale levimiskiirusele \u00f5hus, ja arvutada tegelik kaugus v\u00e4ljalaskepunktist takistuseni vastavalt v\u00e4ljalaske ja vastuv\u00f5tmise vahelisele ajavahele. Kui k\u00fclgnevate s\u00f5lmede veetase on erinev, saab selle \u00fclemises arvutitarkvaras esile t\u00f5sta, et probleemi kiiremini lahendada.<\/p>\n\n\n\n

2.2 Puuraugu kaane oleku tuvastamine<\/p>\n\n\n\n

G\u00fcroskoobi moodulit kasutatakse v\u00f5lli katte nurga muutuse tuvastamiseks, et hinnata, kas kate on lahti v\u00f5i avatud ilma p\u00f5hjuseta, et realiseerida vargusvastase ja l\u00f5tvuse tuvastamise funktsioon.<\/p>\n\n\n\n

MPU6050-l on nurkkiirenduse ja kiirenduse tuvastamise funktsioon ning t\u00e4psus on v\u00e4ga k\u00f5rge. See suudab tuvastada nurga mikromuutusi. I2C sideprotokolli kasutamine on v\u00e4ga lihtne. Mpu6050 saab puuraugu kaanele horisontaalselt kinnitada. Kui puuraugu kaas avatakse, suudab moodul tuvastada nurga muutuse ja anda tagasisidet. Kui puuraugu kaas on lahti ja keegi v\u00f5i s\u00f5iduk l\u00e4bib kaant, muutub kaane nurk veidi. MPU6050 tagastatud teabe p\u00f5hjal saab otsustada, kas puuraugu kaas on lahti v\u00f5i mitte. Kui puuraugu kaane kalle on suurem kui 30\u00b0, loetakse kaas avatud; kui nurk on -5\u00b0\uff5e5\u00b0 pideva k\u00f5ikumisega, loetakse kaas lahti olevaks.<\/p>\n\n\n\n

2.3 Pinna keskkonnaseire<\/p>\n\n\n\n

J\u00e4lgige pinna temperatuuri ja niiskust, hinnake ilmastikutingimusi ja andke teatud tagasisidet.<\/p>\n\n\n\n

2.3.1 Niiskuse tuvastamine<\/p>\n\n\n\n

Niiskusanduri paigaldamine puurkaevu kaane siseserva tuvastab niiskusesisalduse reaalajas ja annab tagasisidet iga s\u00f5lme kesksele t\u00f6\u00f6tluss\u00fcsteemile. Kui vihmase ilmaga on \u00f5huniiskus k\u00f5rge v\u00f5i pinnavesi tungib andurisse puurkaevu kaane serva kaudu ja \u00f5huniiskus \u00fcletab teatud v\u00e4\u00e4rtuse, reageerib keskne t\u00f6\u00f6tluss\u00fcsteem, parandab suhtlussagedust hostiga ja annab tagasisidet reaalajas, mis on juhtidele abiks lisateabe hankimisel h\u00e4daolukorras.<\/p>\n\n\n\n

2.3.2 Temperatuuri tuvastamine<\/p>\n\n\n\n

Temperatuurianduri kinnitamine kaevu kaane alla pinnatemperatuuri teabe kogumiseks ja edastamiseks on abiks linnavalitsusele, et saada \u00fclevaade temperatuurist linna eri osades ja v\u00f5tta jahutusmeetmeid liiga k\u00f5rge temperatuuriga piirkondades. (\u00dclemist arvutit saab kasutada temperatuurimuutuse k\u00f5vera genereerimiseks ja tulevase temperatuuri ennustamiseks.)<\/p>\n\n\n\n

Kasutatakse temperatuuriandurit LM35DZ. Kiip on v\u00e4ikese ja paindliku suurusega ning suure t\u00e4psusega. Andmete t\u00e4psus on kuni kaks k\u00fcmnendkohta. Kiip saab kasutada \u00fche siiniga kommunikatsioonire\u017eiimi ja on h\u00f5lpsasti kasutatav.<\/p>\n\n\n\n

2.4 Liiklusvoo j\u00e4lgimine<\/p>\n\n\n\n

Autode tuvastusmoodul paigaldatakse kaevu kaanele, et tuvastada liiklusvoogu ja edastada see omavalitsuse haldusosakonnale viitamiseks.<\/p>\n\n\n\n

S\u00f5idukivoolu j\u00e4lgimise funktsiooni realiseerimiseks on plaanis kasutada geomagnetilist andurit. Moodul suudab t\u00e4pselt tuvastada magnetv\u00e4lja olukorda. M\u00f6\u00f6duvate s\u00f5idukite korral h\u00e4irib see magnetv\u00e4lja. Kui moodul tuvastab magnetv\u00e4lja muutuse, saab see otsustada, kas m\u00f6\u00f6duvad s\u00f5idukid. Praegu kasutatakse moodulit peamiselt parkimiskoha tuvastamiseks. Mooduli peamised eelised on j\u00e4rgmised:<\/p>\n\n\n\n

(1) V\u00e4ike ja paindlik suurus. Moodulit saab toodetes h\u00f5lpsasti kasutada;<\/p>\n\n\n\n

(2) K\u00f5rge tundlikkus. Moodul on v\u00e4ga tundlik Maa magnetv\u00e4lja muutuste suhtes ja suudab tuvastada s\u00f5iduki liikumist kaugemal kui 3 m;<\/p>\n\n\n\n

(3) \u00dclimadal energiatarve. Mooduli keskmine t\u00f6\u00f6vool on alla 200 \u03bcA. Ja selle t\u00f6\u00f6pinge v\u00f5ib olla kuni 2,0 V, mis aitab aku kasutusaega maksimeerida (kaks nr 5 Nanfu akut v\u00f5ivad t\u00f6\u00f6tada \u00fcle 3 kuu, professionaalsed suure mahutavusega t\u00f6\u00f6stuslikud akud v\u00f5ivad t\u00f6\u00f6tada \u00fcle 5 aasta, \u00fclisuure mahutavusega akud v\u00f5ivad t\u00f6\u00f6tada isegi \u00fcle 10 aasta v\u00f5i aku s\u00e4ilivusaja j\u00e4rgi).<\/p>\n\n\n\n

(4) Lihtne ja h\u00f5lpsasti kasutatav. Moodul pakub l\u00fclitiliidest ja UART-jadaporti. L\u00fclitiliides pakub k\u00f5rge- ja madalatasemelist v\u00e4ljundit. K\u00f5rge tase t\u00e4hendab, et auto on olemas, madal tase t\u00e4hendab, et autot pole; UART-jadaport pakub ajastuse oleku aruandlust, parameetrite seadistamist ja muid funktsioone.<\/p>\n\n\n\n

2.5 Andmeedastus<\/p>\n\n\n\n

2.5.2 NB-IOT osa<\/p>\n\n\n\n

Nb-IOT osa kasutatakse keskkontrolleri (Beaglebone) t\u00f6\u00f6deldud teabe internetti saatmiseks. NB-IOT-i kasutamisel andmete edastamiseks on j\u00e4rgmised eelised:<\/p>\n\n\n\n

(1) NB-IOT signaal h\u00f5lmab laia ulatust, mis tagab k\u00f5igi andmete sujuva edastamise internetti;<\/p>\n\n\n\n

(2) V\u00f5rgu kiirus v\u00f5ib ulatuda umbes 20 K sekundis, mis on andmete edastamiseks piisav;<\/p>\n\n\n\n

(3) V\u00f5rreldes SMS-iga on NB-IOT-i kasutamise kulud andmeedastuseks madalamad;<\/p>\n\n\n\n

(4) Seeriaprotokolli kasutamine on lihtne<\/p>\n\n\n\n

2.5.3Serveri osa<\/p>\n\n\n\n

Arvestades, et NB-IOT mooduli kasutatav IP-aadress m\u00e4\u00e4ratakse juhuslikult, peavad kasutajad sisse logima erinevate IP-seadmetega, mist\u00f5ttu on kogutud teabe otse kasutajate seadmetesse saatmine keeruline. Seet\u00f5ttu otsustati andmeedastusjaamana kasutada serveriplatvormi. Kogu kogutud teave saadetakse NB-IOT kaudu serverisse ajutiseks salvestamiseks ja kasutaja kasutab andmete hankimiseks serverile juurdep\u00e4\u00e4suks \u00fclemist arvutit.<\/p>\n\n\n\n

2.7 Intelligentne juhtimisliides<\/p>\n\n\n\n

\u00dclemine arvuti saab serveriplatvormilt andmed ja esitab need kasutajale visualiseeringu kujul. Visuaalse liidese kaudu saab kasutaja intuitiivselt aru iga s\u00f5lme asukoha suhtest ning mugavalt hankida iga s\u00f5lme veetaseme, temperatuuri, niiskuse, puurkaevu kaane oleku, liiklusvoo ja muu teabe. Erinevate ebanormaalsete tingimuste, n\u00e4iteks ummistuse, veetaseme kiire t\u00f5usu v\u00f5i puurkaevu kaane ebanormaalse oleku korral saab kasutaja \u00f5igeaegselt tagasisidet oleku ja asukoha kohta.<\/p>\n\n\n\n

\u00dclemine arvuti kasutab Baidu kaardi pakutavat API-t, et kuvada veebilehel j\u00e4lgitava ala kaarti, ja iga s\u00f5lm on kaardil m\u00e4rgitud, mis on v\u00e4ga ilmne. Kasutades Pythoni keele Django arhitektuuri ning HTML-i, JS-i ja teisi keeli, esitatakse iga s\u00f5lme kogutud andmed veebilehel diagrammi kujul ja saate neid sildile kl\u00f5psates kontrollida. Samal ajal saab h\u00e4irefunktsioon kasutajat probleemidest \u00f5igeaegselt teavitada.<\/p>\n\n\n\n

  1. \u00dcldine plokkskeem<\/li><\/ol>\n\n\n\n

    S\u00fcsteemi \u00fcldine plokkskeem on n\u00e4idatud joonisel 4 ja l\u00f5puks realiseeritakse j\u00e4rgmised funktsioonid:<\/p>\n\n\n\n

    (1) Sissemurdmish\u00e4ire, v\u00f5rgu kaudu teavitatakse omavalitsus\u00fcksusi, et lahendada \u00f5igeaegselt puuduva kaevu katte probleem.<\/p>\n\n\n\n

    (2) Lahtine alarm, k\u00f5rvaldab jalak\u00e4ijatele kaevu katte kahjustustest tuleneva v\u00f5imaliku ohu.<\/p>\n\n\n\n

    (3) Torustiku ummistuse h\u00e4ire kuvab visuaalses liideses ummistuse, et aidata puhastusosakonnal \u00f5igeaegselt puhastada, k\u00f5rvaldada varjatud ohud ja v\u00e4ltida linna veevoolu teket.<\/p>\n\n\n\n

    (4) M\u00f5\u00f5ta maapinna temperatuur ja saada andmed tagasi.<\/p>\n\n\n\n

    (5) M\u00f5\u00f5da veetaset ja saada andmed tagasi.<\/p>\n\n\n\n

    (6) Tuvastage maapinna niiskustase ja suurendage edastussagedust niiskuse t\u00f5ustes, mis on kasulik tugeva vihma hoiatuse korral.<\/p>\n\n\n\n

    (7) Tuvastada s\u00f5idukite voogu, saata andmeid reaalajas tagasi ja abistada liikluse korraldamist.<\/p>\n\n\n\n

    (8) Kuva tagastatud andmed visualiseerimisliideses ning teosta vastav t\u00f6\u00f6tlemine ja klassifitseerimine, mis pakub munitsipaalosakondadele mugavat t\u00f6\u00f6keskkonda.<\/p>\n\n\n\n

    (9) Loo andmebaas tagastatud andmete salvestamiseks, et neid oleks lihtne kasutada ja anal\u00fc\u00fcsida.<\/p>\n\n\n\n

    4 Kokkuv\u00f5tvad m\u00e4rkused<\/p>\n\n\n\n

    S\u00fcsteemi eesm\u00e4rk on luua linnale intelligentne omavalitsuse haldusplatvorm, mis pakuks avalikkusele mugavamat ja turvalisemat elu. Projekti peamine uuendus on puurkaevu kaane kasutamine piirkondliku koondumiss\u00f5lmena, kogutud andmete tsentraliseeritud edastamine ja intelligentne t\u00f6\u00f6tlemine. Projekti tipphetk on nutika linna ehitamine, mis v\u00f5tab arvesse drenaa\u017ei, liiklust, liiklusohutust ja muud omavalitsuse teavet. Kuigi elektrivarustuse ja antenniga on endiselt probleeme, pole inseneridel neid keeruline lahendada, mis pakub suuremat garantiid inimeste ohutusele ja elukvaliteedile.<\/p>","protected":false},"excerpt":{"rendered":"
