Ho ea ka litlhoko tsa theknoloji tsa bahlahisi ba fapaneng, mekhoa e nepahetseng ea ho lekanya bolelele ba li-tubes ka mekhoa e fapaneng ea ho lekanya bolelele. Ho na le tse latelang:
1, Tekanyo ea bolelele ba grating
Molao-motheo oa motheo ke: lipheletsong tse ka ntle tsa li-tubes tse nepahetseng li fanoa ka bolelele bo tsitsitseng ba li-grating tse peli, tšebeliso ea grating e se nang rodless cylinder e khanna haufi le li-tubes tse nepahetseng, ho sebelisa tšitiso ea leseli ho finyella tekanyo e nepahetseng ea bolelele ba tube.
E tšoauoa ka ho nepahala ho phahameng. Empa tekanyo e theko e boima ebile e thata ho e boloka, phello ea lerōle le ho sisinyeha ke sebaka se hlokolosi haholo.

2, Tekanyo ea bolelele ba khamera.
Tekanyo ea bolelele ba k'hamera ke ts'ebeliso ea ts'ebetso ea litšoantšo ho fihlela tekanyo e nepahetseng ea bolelele ba li-tubes, molao-motheo ke letoto le lekanang la li-switch tsa photoelectric tse kentsoeng ka har'a tube ea conveyor e nepahetseng ka nako e itseng, ho eketseha ha leseli le khamera karolong e 'ngoe. Ha li-tubes tse nepahetseng sebakeng sena li ka khethoa ke lik'hamera tse nepahetseng tsa bolelele ba li-tube tse nkang setšoantšo skrineng se le maemong a ipapisitseng le switch ea photoelectric.
Likarolo li fumaneha bakeng sa ho lekanya marang-rang, li-tubes tse nepahetseng li ka fumanoa ka ho lekanya bolelele ba data ha sebaka se selelele, ho se na nako. Khaello ke: Haeba u sa fane ka mohloli oa khanya, li-tubes tse nepahetseng li tla kena-kenana le tšitiso e ka ntle, empa ka mor'a ho sebelisa leseli ka lebaka la li-tubes tsa ad hoc precision ka mor'a hore li-tube tsa chamfered li qetelle ha khanya e khanyang e le matla haholo. ho baka diphoso tsa ho bala.

3, Encoder e lekanya bolelele
Molao-motheo ke ho kenya encoder ka silindara ho silindara ho khothaletsa ts'ebeliso ea li-tubes tse nepahetseng ka har'a motsamao oa li-rollers ka lehlakoreng le leng la letoto le ntseng le phahama la li-switch tsa photoelectric, li-tubes tse nepahetseng li fihlelleha ha li-cylinders tsa switch photoelectric li sutumelletsa pheletso ea tube, ho tsoa ho 'malo oa ho rekota oa khouto, o fetotse sekhahla sa silinda, hore o tsebe ho bala bolelele ba li-tubes tse nepahetseng.
E tšoauoa ka tlhokahalo ea ho phahamisa li-tubes tse nepahetseng tse lekanyang bolelele. Ho phaella moo, ho na le phetoho e itseng ea photoelectric e lemoha phoso, u ka 'na ua hloka ho lekanyetsoa ka botlalo.

4, Encoder ea ho lekanya bolelele e ntlafalitsoeng
Mokhoa ona ke tekanyo e sa tobang, ka ho lekanya sebaka se pakeng tsa li-tubes tse peli tse nepahetseng ka ntlha e fapaneng e lekantsoeng ka mokhoa o sa tobang bolelele ba li-tube. Ka li-tubes tse nepahetseng lipheletsong tse peli tsa seteishene sa ho lekanya ho theha koloi e telele, boemo ba pele ke boemo ba zero, sebaka sa L. Ebe u tsamaisa bolelele ba tube e nepahetseng ea mohlophisi ho isa pheletsong e 'ngoe le e 'ngoe ea sebaka se tsamaeang (L2, L3), L-L2- L3, ke bolelele ba li-tubes tse nepahetseng.
