Kutshanje, ukuchongwa kobushushu bemitha kwindawo ephilayo kunye nemithombo yamanzi kuye kwaba sisihloko esixhalabisayo.Ukusabela kule mfuno, i-DWIN iphuhlise ngokukodwa kwaye iyile isisombululo sesixhobo sokutshiza ngemitha esekwe kwi-T5L_COF izikrini ezihlakaniphile, kwaye ivule umthombo woyilo ukuze abasebenzisi babhekisele kuwo.
Ividiyo
1. Umgaqo wokufumanisa
I-counter ye-Geiger sisixhobo sokubala esibona ngokukodwa ubukhulu be-ionizing radiation (i-particles, i-b particles, i-g ray kunye ne-c rays).Umbhobho ozaliswe yigesi okanye igumbi elincinci lisetyenziswa njengeprobe.Xa i-voltage esetyenzisiweyo kwi-probe ifikelela kuluhlu oluthile, i-ray i-ionized kwi-tube ukuvelisa i-ion ions.Ngeli xesha, i-pulse yombane yobukhulu obufanayo iyanyuswa kwaye ingabhalwa ngesixhobo sombane esixhunyiwe.Ngaloo ndlela, inani lemitha ngexesha leyunithi lilinganiswa.Kule nkqubo, i-counter ye-Geiger ikhethiwe ukuze ibone ubukhulu be-radiation yento ekujoliswe kuyo.

Umfanekiso ongentla ubonisa iiparamitha zokusebenza ezihambelana neemodeli ezahlukeneyo.Esi sisombululo somthombo ovulekileyo sisebenzisa i-J305.Inokubonwa kumzobo wokuba i-voltage yayo yokusebenza i-360 ~ 440V, kwaye ukunikezelwa kwamandla kuxhaswe yi-3.6V ibhetri ye-lithium eqhelekileyo, ngoko ke isiphaluka sokunyusa kufuneka siyilwe.
2. Umgaqo wokubala
Emva kokuba i-counter ye-Geiger isebenze ngokuqhelekileyo, xa i-radiation idlula kwi-counter ye-Geiger, i-pulse yombane ehambelanayo iyenziwa, enokuthi ibonwe ngokuphazamiseka kwangaphandle kwe-chip ye-T5L, ngaloo ndlela ifumana inani lee-pulses, ezithi ziguqulelwe kwi-chip. iyunithi yomlinganiselo efunekayo ngendlela yokubala.
Kucingelwa ukuba ixesha lesampulu ngumzuzu omnye, ubuzaza bomlinganiselo yi-210 CPM/uSv/hr, inani le-pulse elilinganisiweyo ngu-M, kunye neyunithi esetyenziswa ngokuqhelekileyo ukulinganisa ubunzulu bemitha nguSv/hr, ngoko ke ixabiso ekufuneka silibonisile ngu-K. = M/210 uSv /hr.
3. Isiphaluka esiphezulu sombane
Ibhetri ye-3.6V Li-ion inyuswe ukuya kwi-5V ukunika amandla kwisikrini se-COF, kwaye emva koko isikrini se-COF se-PWM sikhupha i-10KHz yesikwele samaza kunye nomjikelezo womsebenzi we-50%, oqhuba i-inductor DC / DC yokunyusa kunye ne-back-voltage. iisekethe ukufumana 400V DC ukuba bias unikezelo lwamandla kumbhobho Geiger.
