Munguva pfupi yadarika, kucherechedzwa kwemwaranzi intensity munzvimbo dzinogara uye mitumbi yemvura yave nyaya yekunetsa kwakapararira.Mukupindura kudiwa uku, DWIN yakanyatso gadzira uye nekugadzira dhizaini yekuvheneka mhinduro yakavakirwa paT5L_COF smart skrini, uye yakavhura dhizaini kuti vashandisi vataure nezvayo.
Vhidhiyo
1. Kuona musimboti
Kaunda yeGeiger chishandiso chekuverenga chinonyatso kuona kusimba kwemwaranzi yeionizing (zvimedu, b particles, g rays uye c rays).Iyo chubhu yakazadzwa negasi kana kamuri diki inoshandiswa se probe.Kana iyo voltage inoshandiswa kuprobe inosvika kune imwe nhanho, ray inoiswa ionized muchubhu kuti ibudise peya yeion.Panguva ino, kuputika kwemagetsi kwehukuru hwakafanana kunowedzerwa uye kunogona kunyorwa nemagetsi akabatanidzwa.Saka, nhamba yemaranzi payuniti nguva inoyerwa.Muchirongwa ichi, kaunda yeGeiger inosarudzwa kuti ione kusimba kwemwaranzi yechinhu chakanangwa.

Mufananidzo uri pamusoro unoratidza maitiro ekuita anoenderana nemhando dzakasiyana.Iyi yakavhurika sosi mhinduro inoshandisa J305.Zvinogona kuonekwa kubva pamufananidzo kuti simba rayo rekushanda i360 ~ 440V, uye simba rekushandisa rinoshandiswa nekazhinji 3.6V lithium bhatiri, saka inosimudzira circuit inoda kugadzirwa.
2. Kuverenga musimboti
Mushure mekunge Geiger counter iri mukushanda kwakajairika, kana radiation ichipfuura nepakati peGeiger counter, inoenderana nemagetsi pulse inogadzirwa, iyo inogona kuonekwa nekukanganiswa kwekunze kweT5L chip, nokudaro kuwana nhamba yemapulses, iyo inozoshandurwa kuita Chiyero chinodiwa nenzira yekuverenga formula.
Tichifunga kuti nguva yesampling iminiti 1, kuyerwa kwekuyeresa i210 CPM/uSv/hr, yakayerwa pulse nhamba iM, uye iyo inowanzo shandiswa yekuyera radiation intensity isv/hr, saka kukosha kwatinoda kuratidza K. = M/210 uSv/hr.
3. High voltage circuit
Iyo 3.6V Li-ion bhatiri inokwidziridzwa kusvika ku5V kupa simba kuCOF skrini, uyezve COF skrini PWM inoburitsa 10KHz square wave ine duty cycle ye50%, inotyaira inductor DC/DC kuwedzera uye kumashure-voltage. maseketi kuti atore 400V DC kurerekera kune magetsi kuGeiger chubhu.
