1. Nhanganyaya: Mhinduro Yemazuva Ano Yehungwaru hweIvhu
Sensor yevhu inonzi RS485 chishandiso chekutarisa chakagadzirwa kuti chipe ruzivo rwechokwadi pamusoro pehunyoro nekupisa kwevhu munzvimbo dzakasiyana-siyana dzakamira. Nekushandisa tekinoroji yeFrequency Domain Reflectometry (FDR), masensor aya anoyera dielectric constant yevhu kuti averenge huwandu hwemvura neunyanzvi hwakanyanya. Iyi tekinoroji yakakosha pakurima kwemazuva ano, ichipa RS485 Modbus RTU connectivity yakagadzikana inodiwa kumasisitimu ekudiridza otomatiki, manejimendi yezviwanikwa zvinogara kwenguva refu, uye tsvakiridzo yenguva refu yezvakatipoteredza.
2. Nei Kutarisa Kwemachira Akasiyana-siyana Kuchikosha Pakudiridza Kwakanyatsonaka
Mukutarisira ecosystem yehunyanzvi, data repamusoro-soro hariwanzo kukwana. Mwero wehunyoro pa10cm unogona kusiyana zvakanyanya neuri pa40cm, uko kunowanzogara midzi yakakosha. Kunzwisisa chimiro ichi chakamira ndicho chinhu chikuru chekuvandudza goho rezvirimwa nehutano.
Kubatsira kweProfile Yakamira
Masensa edu anoshandisa chimiro chepakati chakaiswa mativi kuti ape ruzivo rwakakwana pamusoro pekoramu yevhu. Magadzirirwo aya anobvumira vagadziri vemapurazi nevarimi kuti:
3. Kunyura Mumvura Yakadzika: Kubatsira Kwetekinoroji yeHonde
Muruzivo rwedu senyanzvi dzekugadzirisa mhinduro dzeIoT, zvinhu zvikuru zvinokanganisa kushandiswa kwekurima inyaya yekupinda kwezvakatipoteredza uye kusagadzikana kwemagetsi. Takagadzira sensor yeHonde soil tubular RS485 kuderedza njodzi idzi kuburikidza ne epoxy resin encapsulation uye kuvaka imba yakasimba yeindasitiri.

4. Kubatanidza Soil Tubular Sensor RS485 kuburikidza neModbus RTU
Kune mugadziri weIoT, kuvimbika kwebhazi rekutaurirana kwakakosha sekururama kwesensa. Iyo RS485 interface inobvumira kumhanya kwetambo kure, kunyangwe tichikurudzira kushandisa 120-ohm termination resistor yekumhanya kupfuura mamita zana kudzivirira kuratidzwa kwechiratidzo.
Tsanangudzo dzeWiring
Waya dzakajairwa dzinoita kuti kubatana pakati pePLC, RTU, uye edge gateways zvive nyore:
| Ruvara | Basa |
|---|---|
| Tsvuku | Simba Rakanaka (+) |
| Nhema | Simba Risina Kunaka (-) |
| Yero | 485A |
| Girinhi | 485B |
[Isa Mufananidzo: Dhiyagiramu yeMagadzirirwo eSystem. Alt-text: Dhayagiramu inoratidza masensa akawanda evhu ane machubhu edaisy akasungirirwa kuburikidza neRS485 muHonde 4G/MQTT Gateway, iyo inozotumira data kune central cloud server.]
Makero eRejista yeModbus RTU (Standard 4-Layer)
Chinyorwa cheMugadziri:Data rinodzoserwa se16-bit integers. Kuti uwane kukosha chaiko, nhamba inodzoserwa inofanira kukamurwa ne100 (semuenzaniso, kuverenga kwe2550 kunomiririra 25.50% kana 25.50℃).
| Kero | Paramita | Rudzi rweData | Zviyero |
|---|---|---|---|
| 0×0000 | Huremu hwemvura (Dura 1 - 10cm) | Int Isina Kusainwa | % (Inhamba/100) |
| 0×0001 | Kupisa kwevhu (Dura 1 - 10cm) | Yasainwa Int | ℃ (Inhamba/100) |
| 0×0002 | Huremu hwemvura (Dura 2 - 20cm) | Int Isina Kusainwa | % (Inhamba/100) |
| 0×0003 | Tembiricha yevhu (Dura 2 - 20cm) | Yasainwa Int | ℃ (Inhamba/100) |
| 0×0042 | Nguva Yekurodha Inoshanda | Int Isina Kusainwa | Maminetsi (0 = Kudzima; >1 = Kuvhurwa) |
Kupfuura RS485 ine waya, Honde Technology inopa mhinduro dzakabatana dze 4G ne MQTT kumapurojekiti anoda kuona data zvakananga kubva ku cloud kuenda ku mobile pasina zvivakwa zviripo panzvimbo iyi.
5. Kuisa SOP: Nzira yeKutsvedza Mud
Chinoongorora zvakanyatsonaka chinoshanda chete kana chakabatana nevhu. Nzira yekutsvedza kwevhu ndiyo nzira inonyanya kufarirwa yekuona kuti chubhu yePVC ye40mm nevhu rakatenderedza harina musono, risina mhepo.
Semugadziri wezvivakwa, ndinokurudzira vatengi kuti vasateerere data rekutanga mumaawa makumi maviri nemana kusvika makumi mana nemasere. Ivhu rinofanira "kugadziriswazve" uye ivhu rinofanira kudzokera pariri zvaro zvisati zvaonekwa kuti FDR readings. Pamusoro pezvo, dzivisai kuisa munzvimbo dzine tembiricha iri pasi pe zero, sezvo chando chichawedzera uye chichikonzera zvinhu zvakakosha zvekuyera.
6. Kugadzirisa Matambudziko uye Kusarudza Nzvimbo yeSoil Tubular Sensor RS485
Kuisa hurongwa hwakakodzera ndiyo danho rekupedzisira mukuona kuti data remapurojekiti ekurima eB2B rakavimbika.
Maitiro Ekusarudza Nzvimbo
Zvikanganiso Zvakajairika & Mhinduro
| Mhosva | Chingangove Chikonzero | Mhinduro yeMugadziri weMapurani |
|---|---|---|
| Kukundikana kweComm | Mutengo we baud kana kero isiriyo | Simbisa baud (inogona kusarudzwa 1200–9600, default 9600) uye 8N1 settings. Tarisa A/B polarity. |
| Dhata reZero Rinogara Richiitwa | Maburi emhepo kana kusabatana kwemhepo | Shandisa nzira yekubvisa madhaka kuti ubvise mapombi emhepo akakomberedza chubhu. |
| Hapana Kurodha Kunoshanda | Nyorera 0×0042 misconfig | Ita shuwa kuti Register 0×0042 yakaiswa pa ≥1 (chikamu: maminitsi). |
7. Mhedziso & Maitiro ebhizinesi
Sisitimu yakabatana yeHonde Technology yekutarisa ivhu inovhara musiyano uripo pakati pedata rezvakatipoteredza risina kugadzirwa uye ruzivo rwezvekurima runogona kushandiswa. Nekubatanidza kunzwisiswa kweFDR kwakanyatsojeka pamwe nekuvimbika kwemaindasitiri kweRS485 Modbus RTU protocol, tinopa vatengi veB2B mhinduro inokwenenzverwa, inonyudzwa mumvura, uye ine simba shoma kumapurojekiti ekudiridza anonetsa zvikuru.
Kunyangwe uri kubatanidza masensa aya kune network yePLC iripo kana kuti uchida mhinduro yakazara ye4G/MQTT cloud, timu yedu yeinjiniya yakagadzirira kukubatsira.
