【Open Source】 Radiation Detector Solution Yotengera T5L_COF Smart Screen

Posachedwapa, kuzindikira mphamvu ya radiation m'malo okhala ndi m'madzi kwakhala nkhani yodetsa nkhawa kwambiri. Potsatira izi, DWIN yapanga mwapadera ndikupangira njira yowunikira ma radiation yotengera T5L_COF zowonera, ndipo yatsegula magwero omwe ogwiritsa ntchito angatchule.

1. Mfundo yodziwira
Kauntala ya Geiger ndi chida chowerengera chomwe chimazindikira mphamvu ya cheza cha ionizing (tinthu tating'onoting'ono, tinthu tating'onoting'ono, ma g ray ndi c ray). Chubu chodzaza gasi kapena chipinda chaching'ono chimagwiritsidwa ntchito ngati kafukufuku. Mphamvu yamagetsi yomwe imagwiritsidwa ntchito pa kafukufukuyo ikafika pamtundu wina, kuwalako kumapangidwa ndi ionized mu chubu kuti apange ma ion. Panthawiyi, mphamvu yamagetsi yofanana ndi kukula kwake imakulitsidwa ndipo imatha kulembedwa ndi chipangizo chamagetsi cholumikizidwa. Choncho, chiwerengero cha cheza pa unit nthawi amayesedwa. Mu pulogalamuyi, kauntala ya Geiger imasankhidwa kuti izindikire kuchuluka kwa ma radiation a chinthu chomwe mukufuna.

Chithunzi pamwambapa chikuwonetsa magawo a magwiridwe antchito ofanana ndi mitundu yosiyanasiyana. Njira yotsegukayi imagwiritsa ntchito J305. Zitha kuwoneka kuchokera pazithunzi kuti magetsi ake ogwira ntchito ndi 360 ~ 440V, ndipo magetsi amayendetsedwa ndi batire wamba ya 3.6V ya lithiamu, kotero kuti dera lothandizira liyenera kupangidwa.

2. Mfundo yowerengera
Pambuyo poyang'anira Geiger ikugwira ntchito bwino, ma radiation akadutsa pa counter ya Geiger, mpweya wofanana wamagetsi umapangidwa, womwe ukhoza kuzindikiridwa ndi kusokonezeka kwa kunja kwa chipangizo cha T5L, motero kupeza chiwerengero cha pulses, chomwe chimasinthidwa kukhala muyezo wofunikira pogwiritsa ntchito fomula yowerengera.
Pongoganiza kuti nthawi yoyeserera ndi mphindi imodzi, mphamvu ya kuyeza ndi 210 CPM/uSv/hr, kugunda kwa mtima ndi M, ndipo gawo lomwe limagwiritsidwa ntchito poyeza kuchuluka kwa ma radiation ndi uSv/hr, ndiye mtengo womwe tikuyenera kuwonetsa ndi K. = M/210Sv/h.

3. Kuzungulira kwamagetsi apamwamba
Batire ya 3.6V Li-ion imakulitsidwa mpaka 5V kuti ipereke mphamvu pazithunzi za COF, kenako chophimba cha COF PWM chimatulutsa mafunde apakati a 10KHz ndi kuzungulira kwa 50%, komwe kumayendetsa inductor DC/DC mphamvu ndi kumbuyo kwamagetsi. mabwalo kuti atenge 400V DC kuti asakondera magetsi ku chubu la Geiger.
