Bokhoni ba ho lekanya ka mor'a hore ho rema lifate ho phetheloe ho ntlafatsa ho nepahala ha data. E lumella hore ho be le litokiso tse ipapisitseng le maemo a tlase a tlase nakong ea ho rema lifate, e leng monyetla oa ho ntlafatsa tlhaloso ea liphetho.
④ Tekanyo le tekanyo ea azimuth e amanang
Karolo ena e fana ka leseli mabapi le sebopeho sa sesebelisoa selibeng, e leng sa bohlokoa bakeng sa tlhaloso e nepahetseng ea data, haholo-holo lilibeng tse khelohileng kapa tse tšekaletseng. E thusa ho utloisisa boemo ba sesebelisoa mabapi le seliba le sebopeho.
⑤ Sebopeho sa sensor se ikemetseng
Li-sensor li entsoe e le li-unit tse arohaneng, tse modular. Moralo ona o ntlafatsa ho ts'epahala ha li-sensor tsa motho ka mong li ka nkeloa sebaka kapa tsa bolokoa ntle le ho ama sesebelisoa kaofela. E boetse e nolofatsa mekhoa ea tlhokomelo 'me e ka fokotsa nako ea ho phomola.
⑥Likhetho tse fapaneng tsa phetisetso
Sesebelisoa se ka tsamaisoa ka mekhoa e fapaneng ea ho tsamaisa ho kenyelletsa phala ea ho phunya, li-tubing, slickline, kapa mohala oa mohala. Ho feto-fetoha ha maemo hona ho bohlokoa haholo lilibeng tse khelohileng haholo le tse tšekaletseng moo ho rengoa ha lifate ka terata ho ka bang thata kapa ho ke keng ha khoneha.
⑦ Bokhoni bo boholo ba polokelo ea data
Ka memori ea 10G, sesebelisoa se ka boloka lintlha tse ngata. Sena ke sa bohlokoa bakeng sa lisebelisoa tsa ho rema memori tse hlokang ho rekota lits'oants'o tsohle tsa data bakeng sa ho khutlisoa hamorao.
⑧Ho fumana data ka lebelo le phahameng
Maqhubu a ho reka a 320ms a lumella ho rema lifate ka botlalo, ho nka liphetoho tse potlakileng maemong a liliba. Qeto ena e phahameng e ka ba ea bohlokoa bakeng sa ho khetholla likarolo tse nyane bontong ea samente kapa sebopehong.
⑨Ho bala lintlha ka potlako
Bokhoni ba ho bala data ka nako e fetang 10Mb/s ka mor'a ho rema lifate bo fokotsa haholo nako e hlokahalang ea ho khoasolla le ho qala ho sekaseka data e kentsoeng hang ha sesebelisoa se khutlisitsoe.
⑩ Nako e atolositsoeng ea ho rema lifate
Bokhoni bo boholo ba polokelo bo lumella lihora tse fetang 200 tsa ho rema lifate ho sa khaotse. Sena se bohlokoa haholo-holo likarolong tse telele tse tšekaletseng kapa ha ho hlokahala hore ho rengoe lifate tse ngata.
⑪Bokhoni ba ts'ebetso
Lintlha tse tharo tsa ho qetela li totobatsa melemo ea ts'ebetso:
- Phokotso ea basebetsi: Ho ka hlokahala basebetsi ba fokolang ho sebelisa sesebelisoa.
- Ho boloka nako ea projeke: Ho sebetsa hantle ha sesebelisoa ho ka fokotsa nako ea projeke ka kakaretso.
- Thepa e fokolang: Sebopeho se kopantsoeng sa sesebelisoa le ho feto-fetoha ha sona ho bolela hore ho hlokahala lisebelisoa tse fokolang kapa likotoana tsa lisebelisoa sebakeng sa marang-rang.
