Kuthamanga kwa radarmita, ngati mtundu wamadzimlingomitandiliwiro loyendandi ukadaulo wa microwave, umaphatikizidwa ndi ukadaulo woyezera ndi mulingo wamadzi a radar okhwimamitandiradar velocimeter, yomwe imagwiritsidwa ntchito makamaka pakuyezera madzimlingo ndi liwiro la kuyenda kwa ngalande zotseguka, monga mitsinje, zipata zosungira madzi, maukonde a mapaipi a mtsinje wapansi pa nthaka ndi ngalande yothirira.
Chogulitsachi chikhoza kuyang'anitsitsa bwino kusintha kwa mlingo wa madzi, kuthamanga ndi kutuluka, kuti apereke chidziwitso cholondola cha kayendedwe ka kayendedwe ka kayendetsedwe kake.

Ubwino wake

Radar Flowmeter Ubwino ndi Zoipa
1. Opangidwa kunja kwa 24GHz radar flow mita, 26GHz radar fluid level gauge, CW plane microstrip array antenna radar, kuzindikira kosalumikizana, mankhwala amitundu iwiri-imodzi amatha kuzindikira kuyeza kwa kuthamanga, kuchuluka kwa madzi, kutuluka nthawi yomweyo ndi kuchulukirachulukira.
2. Ukadaulo wanyengo zonse, wothamanga kwambiri wa ma microwave amatha kuzindikira kuwunika kodziwikiratu, osayang'aniridwa.
3. Mafupipafupi otumizira antenna ndi osinthika komanso osinthika, ndipo mphamvu yotsutsana ndi kusokoneza ndi yamphamvu.
4. Mitundu yosiyanasiyana yolumikizana ndi data RS-232 / RS-485 ikhoza kukhazikitsidwa, yomwe ndi yabwino kwa ogwiritsa ntchito kuti agwirizane ndi dongosolo.
5. Kumanga ndi kukhazikitsa ndi kosavuta, ntchito yoyezera ikuphatikizidwa ndi njira yogona (pafupifupi 300mA panthawi ya ntchito yachizolowezi, ndipo njira yogona imakhala yochepa kuposa 1mA), yomwe imapulumutsa mphamvu ndi kuchepetsa kugwiritsira ntchito, ndipo ndi yachuma komanso yogwira ntchito.
6. Mamita osalumikizana sawononga kayendedwe ka madzi ndikuonetsetsa kuti deta yolondola imayeza.
7. IP67 chitetezo giredi, osakhudzidwa ndi nyengo, kutentha, chinyezi, mphepo, matope ndi zinthu zoyandama, ndi yoyenera malo othamanga kwambiri panthawi ya kusefukira kwa madzi.
8. Anti-condensation, madzi ndi chitetezo cha mphezi, oyenerera malo osiyanasiyana akunja.
9. Maonekedwe ang'onoang'ono, kukhazikitsa kosavuta komanso kukonza kosavuta.
10. Mitundu yapakhomo yomwe ili ndi ufulu wodziyimira pawokha, chithandizo cham'deralo chapantchito.
11. Zigawo zazikuluzikulu zili ndi lipoti la mayeso a "Huadong Testing Center yaChida cha Hydrologicals".

Kugwiritsa ntchito

Ma radar flow meters amagwiritsidwa ntchito kwambiri pofufuza za hydrological, kuyang'anira madzi apansi panthaka, kuyeza madzi ndi mita m'malo othirira, kuyang'anira njira zamtsinje, komanso madzi achilengedwe monga mitsinje, madamu, nyanja, mafunde, ngalande zothirira (njira zotseguka), mitsinje. ngalande, ndi mapaipi a minda. Kuwunika madzi.
Radar flow mita ndiyoyeneranso kudula mitengo yamadzi m'matauni, zimbudzi zam'tawuni, kuwunika kwamadzi am'matauni ndi kuwunika kwamadzi, kuwongolera kusefukira kwamadzi, kusefukira kwamadzi, kuwongolera mapaipi apansi panthaka ndi kuwunika kwina kwamadzi komanso kuwunika kwapaipi yamadzi, kutulutsa madzi, kutulutsa madzi, kutulutsa kwachilengedwe kwa hydropower station. kuyang'anira kayendetsedwe kake ndi zina, zoyenera zigawo zanthawi zonse ndi zosakhazikika .
Dongosolo loyezera kuthamanga kwa radar limatha kuzindikira kusonkhanitsa kwanthawi zonse kwanyengo komanso kuwunika kwenikweni kwa njira yotseguka, kuyenda kwa mitsinje ndi data yamadzi.

Kuyika

Kuyika kwa radar flow mita kuyenera kulabadira kuti mayendedwe a radar wave propagation sangathe kutsekedwa ndi zinthu, apo ayi chizindikiro cha radar chidzachepetsedwa ndipo muyesowo udzakhudzidwa. Mukayika pambali, tikulimbikitsidwa kuti ngodya yopingasa sayenera kupitirira madigiri 45-60.
Poganizira zamitundu yosiyanasiyana yogwirira ntchito, choyamba tiyenera kuganizira zinthu ziwiri izi:

1. Mtundu wa Antenna Beam Range
Kuthamanga kwa mita kumaphatikiza mita ya radar level ndi radar velocimeter. Mlingo wa radar wa radar level mita ndi 11 ° × 11 °, ndipo mbali ya mlongoti wa radar velocimeter ndi 14 × 32 °. Pamene mita yamtunda imawunikira pamwamba pa madzi, malo owunikira amafanana ndi bwalo A, pamene velocimeter imawunikira pamwamba pa madzi, malo owala amafanana ndi elliptical area, monga momwe tawonetsera pa Chithunzi 1.1. Kumvetsetsa bwino kuwala kwa mafunde a radar kumathandiza kusankha malo abwino oti muyikepo ndikupewa zochitika zina zomwe zimakhala zosavuta kusokonezeka, monga mitsinje kumbali zonse za mtsinje, monga nthambi zomwe zikugwedezeka ndi mphepo.

Chithunzi 1.1 Kuyika mulingo wa radar wamamita 10mitandi malo owala a radar velocimeter antenna

Malire a malo amadzi omwe amawunikiridwa ndi radar amafanana ndi kutalika kwa unsembe. Gulu 1.2 likuwonetsa magawo a A, B, ndi D pomwe mtengo wa radarmetendi velocimeter ya radar imawunikira pamwamba pa madzi pamene kutalika kwa kuika ndi mamita 1 (onani Chithunzi 1.1 pa matanthauzo a A, B, ndi D). , kutalika kwenikweni kwa unsembe (mamita unit) kuchulukitsidwa ndi mtengo wotsatira ndi chizindikiro chenichenicho

Dzina	Utali（m）
Radar velocimeter A	0.329
Radar velocimeter B	0.662
Radar level gauge diameter D	0.192

1.2 Antenna beam irradiation surface parameter values

2. Chikoka cha kutalika kwa unsembe pa muyeso panopa
Pansi pazikhalidwe zomwezo, kukweza kutalika kwa unsembe, kufooka kwa echo ndi khalidwe loipa la chizindikiro. Makamaka powonekera ndi kuthamanga kwa madzi otsika, ripple ndi yaying'ono, yomwe imakhala yovuta kwambiri kuti izindikire. Pa nthawi yomweyi, malo a radar wave wave irradiation adzakhala aakulu, ndipo kuwala kwa mtengo kungakhale Pamene ikufika ku gombe la ngalandeyo, imakhudzidwa ndi cholinga chosuntha pa banki. Ngati kuyikako kuli kochepa kwambiri, sikungathandize kuteteza chitetezo chotsutsana ndi kuba, kotero kuti kuikapo, ndi bwino kuti kutalika kwa unsembe ndi 3-4 mamita.

Kuphatikiza pa mfundo ziwirizi, zofunikira zenizeni ndi izi:
1) Mukayika mita yothamanga, mita yamadzimadzi ndi radar yamadzimadzi sizingatsekeke, apo ayi kulondola kwa muyeso kudzakhudzidwa; palibe madzi ochuluka a miyala mu gawo lodziwikiratu, palibe vortex yayikulu, kuyenda kwa chipwirikiti ndi zochitika zina;
2) Njira yodziwira iyenera kukhala yowongoka momwe ingathere, yokhazikika komanso yokhazikika;
3) Radar velocimeter imakhudzidwa kokha ndi chandamale champhamvu. Ngalandeyo ikaumitsidwa ndipo palibe udzu kapena mitengo, ngakhale mtengowo utawunikiridwa mbali zonse za ngalandezi, sizikhudza kuyeza kwake. Kuonjezera apo, gawo la kuyeza koyenda ndilokhazikika momwe zingathere;
4) Gawo lodziwirako liyenera kukhala losalala kuti lipewe kudzikundikira kwa zinthu zoyandama.
5) Mtengo wa mita yamakono ukulimbikitsidwa kuyang'anizana ndi njira ya madzi omwe akubwera, monga momwe tawonetsera pa Chithunzi 1.1, ndi ngodya yopingasa yopita kumayendedwe a madzi ndi madigiri a 0.
6) Mukayika mita yothamanga, yesetsani kuonetsetsa kuti pamwamba pa casing ndi mlingo ndikuyika pakati pa njira.
