Ho utloisisa tlhahiso ea OCT/Pulse

1. Tlhaloso le Khopolo ea Motheo

Sephetho sa OCT

• Sehokelo sa optical, se tsejoang hape e le opto - isolator, ke sona se ka sehloohong sa tlhahiso ea OCT. Se na le leseli la infrared - emit diode (LED) le phototransistor. Ha lets'oao la motlakase le sebelisoa lehlakoreng la ho kenya la sehokelo sa optical, LED e ntša leseli la infrared. Leseli lena ebe le otla phototransistor lehlakoreng la tlhahiso. Ho tsamaisa ha phototransistor hoa fetoha ho latela matla a leseli la ketsahalo. Moelelong oa tlhahiso ea OCT, tlhahiso ea motlakase ho tsoa ho phototransistor e sebelisoa ho fetisa tlhahisoleseling. Tlhahiso ena e ka ba ka sebopeho sa lets'oao la dijithale, le ka bang holimo kapa le tlase, ho latela hore na LED e bonesitsoe kapa che. Tšebeliso ea sehokelo sa optical e fana ka karohano ea motlakase lipakeng tsa lipotoloho tsa ho kenya le tsa tlhahiso. Ho arohana hona ho bohlokoa haholo lits'ebetsong moo ho ka bang le liphapang tse phahameng tsa motlakase kapa lerata la motlakase lehlakoreng la ho kenya le ka sitisang kapa la senya tlhahiso e bonolo - lisebelisoa tsa elektroniki tse ka thoko. Mohlala, tsamaisong ea kabo ea motlakase, moo matšoao a motlakase a phahameng a behiloeng leihlo, tlhahiso ea OCT e ka fetisetsa tlhahisoleseling ka mokhoa o sireletsehileng mabapi le boemo kapalitekanyoea lipotoloho tsena tsa motlakase o phahameng ho ea tsamaisong ea taolo ea motlakase o tlase kapa ea ho beha leihlo ntle le kotsi ea tšitiso ea motlakase kapa lipotoloho tse khutšoane.

Tlhahiso ea Pulse

• Tlhahiso ea pulse e bolela tlhahiso ea letoto la li-pulse tsa motlakase tse arohaneng. Pulse ke phetoho ea nako e khuts'oane boemong ba lets'oao la motlakase, hangata ho tloha boemong bo tlase ho ea boemong bo phahameng ebe e khutlela boemong bo tlase. Litšobotsi tsa li-pulse tsena, joalo ka maqhubu a tsona (palo ea li-pulse ka nako ea yuniti), bophara (nako ea karolo ea boemo bo phahameng ba pulse), le amplitude, li na le tlhahisoleseling. Lisebelisoang tse ngata tsa ho lekanya, joalo ka li-flow metres le li-energy metres, bongata bo lekantsoeng bo fetoloa lets'oao le tsamaellanang la pulse. Mohlala, ho meter ea phallo ea metsi, bophahamo bo bong le bo bong ba yuniti ea metsi bo fetang metering bo ka baka tlhahiso ea pulse e le 'ngoe ea motlakase. Ka ho bala palo ea li-pulse tsena nakong e itseng, bophahamo bohle ba phallo ea metsi bo ka fumanoa. Maqhubu a li-pulse a lekana ka ho toba le sekhahla sa phallo, ka sekhahla se phahameng sa phallo se fellang ka maqhubu a phahameng a pulse.

Mphalane - Tlhahiso ea Pulse e Thehiloeng ho Theolelo

• Litsamaisong tse ling, OCT e sebelisetsoa ho hlahisa tlhahiso ea pulse. Mohlala, khokahanong ea puisano ea dijithale pakeng tsa litsamaiso tse peli tse arohaneng ka motlakase, microcontroller lehlakoreng le romelang e ka romela letoto la matšoao a dijithale. Matšoao ana a sebelisoa ho khanna LED ka har'a optical coupler. Ha microcontroller e fetola letšoao pakeng tsa maemo a holimo le a tlase, LED e bulela le ho tima ka ho loketseng. Phototransistor lehlakoreng le hlahisang e ntan'o hlahisa letoto le tsamaellanang la li-pulse. Ho ikarola ha motlakase ho fanoang ke OCT ho netefatsa hore lerata lefe kapa lefe la motlakase kapa li-voltage transient potolohong e romelang - lehlakoreng ha li ame potoloho e amohelang - lehlakoreng. Sena se thusa haholo libakeng tse nang le tšitiso e ngata ea motlakase, joalo ka lifeme tsa indasteri moo lienjene tse kholo le lisebelisoa tse ling tsa motlakase li sebetsang.

Tlhahiso ea Pulse ho tsoa ho Li-sensor

• Lits'ebetsong tse thehiloeng ho sensor, ts'ebetso ea ho hlahisa tlhahiso ea pulse e amana le bongata ba 'mele bo utluoang. Nka sensor ea ho nka ea makenete e sebelisetsoang ho lekanya lebelo la ho potoloha ha shaft e le mohlala. Sensor e etselitsoe ho lemoha ho feta ha likarolo tsa makenete (joalo ka meno a gear e khomaretsoeng shaft). Nako le nako ha karolo ea makenete e feta pela sensor, e baka phetoho tlhahisong ea sensor. Phetoho ena e beoa 'me e bōptjoa hore e be pulse. Maqhubu a li-pulse tsena a amana ka ho toba le lebelo la ho potoloha ha shaft. Haeba shaft e potoloha ka potlako, likarolo tse ngata tsa makenete li feta pela sensor ka nako ea yuniti, e leng se fellang ka maqhubu a phahameng a pulse. Tlhahiso ena ea pulse e ka romeloa ho microcontroller kapa sesebelisoa se seng sa taolo bakeng sa ts'ebetso e eketsehileng, joalo ka ho bala lebelo la ho potoloha le ho le bontša ho monitor.

Boiketsetso ba Liindasteri

• Litsamaisong tsa othomathike tsa indasteri, tlhahiso ea OCT/pulse e sebelisoa haholo. Mohlala, tsamaisong ea conveyor-belt, li-sensor tsa ho atamelana tse nang le tlhahiso ea pulse li ka sebelisoa ho lemoha boteng le motsamao oa lintho tse holim'a lebanta. Nako le nako ha ntho e feta sensor, pulse ea hlahisoa. Li-pulse tsena li ka baloa ke molaoli oa logic ea programmable (PLC) ho boloka palo ea lintho tse tsamaisoang. Tlhahiso ea OCT e sebelisoa ha li-sensor tsena li hloka ho buisana le PLC ha li ntse li boloka karohano ea motlakase, li sireletsa potoloho ea PLC e bonolo lerata le ka bang teng la motlakase kapa li-voltage tse phahameng tikolohong ea indasteri.

Ho lekanya Matla

• Methareng ea motlakase le khase, tlhahiso ea pulse ke tšobotsi e tloaelehileng. Bakeng sa mithara ea motlakase, tšebeliso ea matla e lekanngoa ho latela palo ea li-watt - lihora tse sebelisitsoeng. Potoloho ea ka hare ea mithara e fetola matla a motlakase a lekantsoeng hore e be letoto la li-pulse. Ha matla a mangata a sebelisoa, li-pulse tse ngata li hlahisoa. Li-pulse tsena li ka romeloa ho logger ea data kapa sistimi e bohlale ea grid bakeng sa ho beha leihlo le ho lefisa hole. Tšebeliso ea tlhahiso ea pulse e nolofatsa ts'ebetso ea puisano 'me e lumella ho kopanngoa habonolo le tse ling.litsamaiso tsa tsamaiso ea matla.

Lisebelisoa le Tekanyo

• Disebedisweng tse fapaneng tsa ho lekanya, tse kang di-oscilloscope le di-frequency counters, tlhahiso ya OCT/pulse e ka sebediswa bakeng sa ho lekanya le ho fetisetsa matshwao. Mohlala, mohlodi wa ho lekanya o ka hlahisa matshwao a nepahetseng a pulse a nang le maqhubu le amplitude tse tsejwang. Di-pulse tsena di ka romelwa ho sesebediswa se lekanngwang ka sebopeho se thehilweng ho OCT ho netefatsa tshebetso e nepahetseng ya tekanyo. Kareteng ya maqhubu, letshwao la ho kenya, leo e ka bang terene ya pulse ho tswa ho sensor kapa kgokelo ya puisano, le balwa le ho sekasekwa ho fumana maqhubu a letshwao.
