Tinofanira Kusarudza 4G kana NB-IoT paMamita Emvura eUltrasonic Here?

Pakusarudza pakati peNB-IoT ne4G kutaurirana kwe ultrasonic water meters, sarudzo yacho inofanira kunge yakavakirwa pane zvinodiwa uye mamiriro ekushandiswa. Heano ongororo yekuenzanisa yematekinoroji maviri aya:

1. Kushandiswa kweSimba

• NB-IoT: Inoshandisa tekinoroji ye "low-power wide-area" (LPWA), iyo module ichiramba iri mu "sleep mode" nguva zhinji. Ichishandisa mabhatiri eAA, hupenyu hwayo hwekushanda hunogona kudarika makore gumi, zvichiita kuti ive yakakodzera mita dzemvura dze ultrasonic dzine simba rakawanda uye inoderedza kuwanda kwekutsiviwa kwemabhatiri.
• 4G: Inoshandisa simba rakawanda, zvichiita kuti bhatiri rigare kwenguva pfupi, izvo zvinova dambudziko guru pakushandiswa kwemamita emvura anoshandisa bhatiri.

2. Kufukidzwa kweNetwork

• NB-IoT: Inopa kuwedzera kwechiratidzo che20dB kana tichienzanisa neGPRS, zvichiita kuti ifukidzwe zvakadzika munzvimbo dzakaoma dzakadai semapaki emaindasitiri, matsime emapipeline, kana kuiswa kwepasi pevhu uko masaini anovharwa zviri nyore.
• 4G: Inoratidza ruzivo rwakakura asi inogona kuomerwa nekugadzikana munzvimbo dziri kure kana munzvimbo dzakaoma (semuenzaniso, dzimba dzepasi dzemumaguta dzakasimba) nekuda kwekusapinda kwemasaini.

3. Kushanda Kwekutumira Data

• NB-IoT: Yakagadzirirwa kutumira data diki, ine frequency shoma (kazhinji kamwe chete mumaawa makumi maviri nemana ekuyera mvura). Yakakodzera mamiriro ezvinhu ane zvinodiwa zvishoma panguva chaiyo, zvakaita sekuverenga mita iri kure uye kuunganidzwa kwedata rekushandisa.
• 4G: Inopa kutumira data nekukurumidza uye kwenguva pfupi, ichitsigira kutarisa panguva chaiyo uye zviziviso zvekukurumidza. Izvi zvinoita kuti ive yakakodzera kune mapurogiramu anoda mhinduro nenguva, akadai sekutarisira mvura yemumaindasitiri, kuona kubuda kwemvura, kana kutarisa zvivakwa zvakakosha.

4. Mutengo

• NB-IoT: Mari yekutaurirana mamodules yakaderera. Kunyange hazvo mari yemodules iri pakati nepakati, mari yekushanda kwenguva refu (semuenzaniso, zvirongwa zvedata) yakaderera nekuda kwekushandiswa kwayo kushoma kwedata.
• 4G: Mari yemodule nehurongwa hwedata zvakakwirira. Pamusoro pezvo, masisitimu akavakirwa pa4G anogona kuda zvivakwa zvekutsigira zvakaoma, zvichikonzera mari yakawanda yekuisa nekuchengetedza.

5. Kukwanisa Kubatanidza

• NB-IoT: Chikamu chimwe chete chechiteshi chinogona kutsigira makumi ezviuru zvekubatanidza, zvichipa mukana wekuwana wakapetwa ka50-100 kupfuura tekinoroji dzechinyakare dzisina waya. Izvi zvinoita kuti ive yakakodzera kushandiswa kweIoT kwakakura, senge network dzemvura dzemumaguta dzine mita dzakakura.
• 4G: Ine mukana mudiki wekubatanidza panguva imwe chete, zvichiita kuti isashande zvakanaka kune maapplication makuru eIoT ane data shoma.

Pfupiso Yekurudziro

• Sarudza NB-IoT yekuyera mvura mudzimba, kure kana kutarisa mvura yemumaguta makuru—mamiriro ezvinhu apo kushandiswa kwesimba shoma, kufukidzwa kwakakura, uye kushanda zvakanaka kwemari zvinokosheswa kupfuura kutapurirana data panguva chaiyo.
• Sarudza 4G yekutarisira mvura mumaindasitiri, kuona kubuda kwemvura panguva chaiyo, kana masisitimu ekutarisa akakosha anoda kutumira data nekukurumidza, kunonoka kwakaderera uye kugona kwekuzivisa nekukurumidza.
