Ndedzipi nzira dzakajairika dzekutaurirana dzemamita emvura e ultrasonic?

Sezvishandiso zvekuongorora zvine hungwaru, ma ultrasound water metres anoshandisa mabasa ekutaurirana kuti akwanise kutumira data, kutarisa data uri kure, uye kutarisira. Nzira dzakajairika dzekutaurirana dzakakamurwa kuva kutaurirana newaya uye kutaurirana pasina waya, seizvi:

I. Nzira dzekutaurirana newaya

1. Kutaurirana kweRS485
   • Ndiyo imwe yenzira dzinonyanya kushandiswa dzekutaurirana newaya mumaindasitiri. Inoshandisa differential signal transmission, ine daro rekutumira rinosvika 1200 metres uye inotsigira multi-point networking (zvishandiso zvinosvika 32 zvinogona kubatanidzwa).
   • Mamita emvura eUltrasonic anobatanidza kune maconcentrator, maPLC, kana makomputa epamusoro kuburikidza neRS485 interfaces kuti awane data rinoiswa panguva chaiyo (senge kuyerera kwemvura panguva imwe chete, kuyerera kwemvura kwakaunganidzwa) uye parameter configuration (senge range, alarm threshold).
   • Nzira yekutaurirana inonyanya kushandisa Modbus-RTU, iyo ine hunyanzvi hwakasimba uye iri nyore kushandisa masisitimu akasiyana-siyana ekudzora.
2. Bhazi reM-Bhazi (Bhazi reMeter)
   • Mwero webhazi wakagadzirirwa zvishandiso zvekuyera, unotsigira simba rebhazi (hapana chikonzero chekupa simba kumamita emvura zvakasiyana), wakakodzera kuverenga mita yemvura, mita yekupisa nezvimwe zvinoshandiswa pakati.
   • Kureba kwekutumira mvura kunogona kusvika mamita anopfuura mazana mashanu, uye kugona kwayo kudzivirira kukanganiswa kuri nani pane RS485. Nekushandisa waya dziri nyore (system yewaya mbiri), inoshandiswa zvakanyanya mukutarisira mita dzemvura munzvimbo dzekugara nedzimba.
3. Kubuda kwePulse
   • Inoshandiswa pakutaurirana kuri nyore newaya. Chiyero chemvura chinoburitsa masaini ekurova kwemoyo kuburikidza nereed switches kana photoelectric sensors, uye huwandu hwekurova kwemoyo hunoenderana nekushandiswa kwemvura.
   • Inowanzo shandiswa kubatanidza nePLCs, vaunganidzi vedata nezvimwe zvishandiso kuti zviite nyore kuyera flow cumulative metering. Ine mutengo wakaderera asi ine basa rimwe chete (inokwanisa chete kutumira data rekushandisa).

II. Nzira dzekutaurirana dzisina waya

1. LoRa (Redhiyo Yenzvimbo Yakareba)
   • Zvichibva pahunyanzvi hwekuparadzira ruzivo, ine daro refu rekutumirwa kwemashoko (makiromita 1-3 mumaguta, makiromita 5-10 mumaguta), simba shoma rinoshandiswa (hupenyu hwebhatiri hunogona kuva makore 5-10), uye inotsigira network yakakura (midziyo inopfuura 1,000).
   • Yakakodzera kuverenga mita dzemvura dziri kure, kunyanya dzinoshandiswa zvakanyanya munzvimbo dzakafara (senge network dzemapaipi emumaguta, masisitimu emvura ekumaruwa). Inogona kutaurirana zvakananga nemagedhi eLoRa, uye yobva yasvika papuratifomu yegore nepagedhi.
2. NB-IoT (Internet yezvinhu zveNarrow Band)
   • Tekinoroji ye network ine simba shoma yakavakirwa pa network dzenharembozha, inofukidzwa nezviteshi zvepasi zvinopihwa nevashandisi, pasina chikonzero chekuvaka magedhi ega. Ine transmission yakagadzikana uye yakafara zvikuru (inogona kupinda mumadziro nemapaipi epasi pevhu).
   • Inotsigira kubatana kukuru (sero rega rega rinogona kubatanidza zvishandiso zviuru zana) uye kushandiswa kwesimba kushoma (hupenyu hwebhatiri makore 3-8), yakakodzera kushandurwa kwakangwara kwemamita emvura mumaguta, ichipinda zvakananga papuratifomu yegore kuti iite kutarisa kuri kure uye kuongorora data.
3. Bluetooth
   • Kutaurirana pasina waya kuri kure (kazhinji mamita 10-100) nekushandisa simba shoma, kunonyanya kushandiswa pakugadzirisa matambudziko panzvimbo uye kuverenga data kure (sekunge vaverengi vemamita vanosvika pamamita emvura nemidziyo inobatwa nemaoko kuti vaverenge data).
   • Hazvina kukodzera kuverenga mita iri kure, asi zvinogona kushandiswa senzira yekubatsira kutaurirana kuti zvive nyore kune vashandi vekugadzirisa kugadzirisa ma parameter kana kugadzirisa matambudziko panzvimbo yacho.
4. GPRS/4G (Network Yenharembozha)
   • Zvichienderana ne network yemushandisi wefoni, ine huwandu hwakanyanya hwekutumirwa kwemashoko uye inogona kutumira data rakawanda munguva chaiyo, asi kushandiswa kwesimba rayo kwakanyanya (inoda magetsi ekunze kana bhatiri rakakura), uye mutengo wacho wakakwirawo zvakanyanya.
   • Yakakodzera mamiriro ezvinhu ane zvinodiwa zvakanyanya pakushanda kwedata panguva chaiyo (sekutarisa mita dzemvura dzemaindasitiri dzakakura) kana senzira yekuchengetedza yekutaurirana kune dzimwe nzira dzisina waya.

• Kutaurirana newaya (RS485, M-Bus) kwakakodzera kuiswa kwakasimba uye kwakamiswa, kuchikosha kugadzikana;
• Kutaurirana kusina waya (LoRa, NB-IoT) kwakakodzera mamiriro ezvinhu akapararira uye makuru, zvichikosha pakuchinjika;
• Kubuda kwepulse neBluetooth zvinonyanya kushandiswa pakuyera zviri nyore kana kugadzirisa matambudziko ekubatsira.
