Mukuita kwelaser processing process debugging, isu tinowanzo kuona iyo "PWM" paramende, saka zvinorevei, ngatizvitarisei nhasi.
PWM ipfupiso ye "Pulse Width Modulation", inonzi "pulse wide modulation" kana "modulation", inzira inoshanda kwazvo yekushandisa kubuda kwedhijitari yemicroprocessor kudzora analog maseketi.
Iyo yekubuda modhi yelaser inonyanya kusanganisira mhando mbiri: inoenderera modhi uye pulse mode.Continuous mode ndiyo inoenderera mberi kupfurwa kwema lasers;Pulse mode ndeyekuburitsa laser panguva imwechete imwe neimwe nguva yenguva.Muenzaniso wakapfava, semwenje unoburitsa mwenje: kubatidza switch haina kudzimwa inoramba ichiita;Kubatidza switch nekukasira woidzima ndiko kuburitsa pulse, uye maitiro ekudzokorodza achibatidza nekudzima ndiyo pulse mode.Saizvozvo, kana tochi ikatsiviwa nelaser, iyo pulse mode ndeyekudzokorora maitiro ekubatidza nekudzima mwenje nguva dzose.
Iyo yakanyanya kunanga nzira yekugadzira iyo pulsed laser ndeyekuwedzera modulator kune CW laser kugadzirisa iyo CW laser kuwana pulse kubuda.PWM (Pulse Width Modulation) ndeyekugadzirisa hupamhi hwepurusi nekugadzirisa kutenderera kwebasa.
Kana uchigadzirisa maparamendi ekucheka laser, pulses uye duty cycles anowanzo shandiswa, uye vazhinji vanoshanda vasingazive iyo laser yekucheka maitiro vanogona kusanzwisisa basa rema paramita maviri aya, vobva vakupa yakadzama sumo.
1Periodicity
Chiratidzo chinoenda kubva kumusoro kusvika pasi uye kudzokera kumusoro kwevhiki imwe chete
2Pulse frequency rate
Mangani mapeji ePWM aripo mu1 sekondi
3Pulse duty cycle
Muenzaniso wereshiyo yenguva yepamusoro-soro kusvika kunguva yese yekutenderera mukutenderera
4Pulse nguva nenguva
Nguva yenguva inotorwa kutenderera
5Pulse width
Inguva yenguva inoshandiswa kwenguva yakareba kune yakakwirira
6Peak simba rate
Iyo yekukurumidza simba kubuda kwelaser mukati meimwe pulse upamhi
7Avhareji yebasa rekushanda
Huwandu hwesimba iro laser inoburitsa mukudzokorora kutenderera
Kazhinji, kana isu tichigadzirisa laser mune laser process debugging, iyo yepamusoro simba, pulse frequency uye basa kutenderera zvinoiswa.Tevere, ngatishandisei muenzaniso kuratidza maverengero ePWM paramita.
Pamusoro pesimba re laser, iyo yebasa kutenderera kwe pulse inowedzera, uye simba pane yega yega pulse irradiation ichawedzera zvinoenderana, izvo zvinowedzera simba rekugadzirisa munzira yekukora kweplate.Kana basa rekutenderera kwepulse rakaderedzwa, simba pane imwe neimwe pulse inovhenekera, iyo inobatsira kuderedza kupisa uye fusing kurasikirwa.
Mukuita simbi, simba relaser rinoshandiswa, uye kana iri simba relaser nguva dzose, iyo yakakwira frequency, idiki simba rekubuda kwelaser yega yega, saka isu tinofanirwa kuona frequency yakakodzera zvichienderana nekumhanya kwekugadzirisa. apo simba re laser rinokwana kunyungudutsa simbi.
GW laser yakavakirwa pa976nm pombi tekinoroji yekuenderera mberi fiber laser zvigadzirwa, ine yakakwira electro-optical shanduko inoshanda, yakanaka kubuda danda mhando, yakanyanya modulation frequency kusvika 50kHz, inoshandiswa zvakanyanya mukucheka, welding, kuchenesa, cladding nekuwedzera kugadzira.
