Punawai Wehe- He Hoʻonā Hoʻopaʻa Radiation Ma muli o ka T5L_COF Smart Screen

I kēia mau lā, ua lilo ka ʻike ʻana i ka ikaika o ka radiation i nā wahi noho a me nā kino wai i mea e hopohopo nui ai.I ka pane ʻana i kēia koi, ua hoʻomohala a hoʻolālā ʻo DWIN i kahi hopena ʻike radiation e pili ana i nā pale akamai T5L_COF, a ua wehe i ka hoʻolālā no nā mea hoʻohana e nānā.

1. Kumu ʻike
ʻO ka counter Geiger kahi mea hana helu e ʻike pono i ka ikaika o ka radiation ionizing (a particles, b particles, g rays and c rays).Hoʻohana ʻia ka paipu piha kinoea a i ʻole ke keʻena liʻiliʻi e like me ka probe.Ke hiki aku ka volta i hoʻohana ʻia i ka ʻimi noiʻi i kahi ākea, ua hoʻoheheʻe ʻia ka hihi i loko o ka paipu e hoʻohua i ʻelua mau ion.I kēia manawa, hoʻonui ʻia kahi pulse uila o ka nui like a hiki ke hoʻopaʻa ʻia e ka mea uila i hoʻopili ʻia.No laila, ana ʻia ka helu o nā kukuna i kēlā me kēia manawa.Ma kēia papahana, koho ʻia ka counter Geiger e ʻike i ka ikaika o ka radiation o ka mea i ʻimi ʻia.

ʻO Geiger Counting Tube Models Shell Material Mea hoʻolalelale ʻia i manaʻo ʻia (unit:CPM/uSv/hr) Voltage hana (unit:V) Plateau range
(unit:V) Kaʻao
(Uni: min/manawa) palena volley (unit:V)
J305bg aniani 210 380 36-440 25 550
M4001 Aniani 200 680 36-440 25 600
J321bg aniani 200 680 36-440 25 600
SBM-20 Ke kila kila 175 400 350-475 60 475
STS-5 Ke kila kila 175 400 350-475 60 475

Hōʻike ke kiʻi ma luna i nā ʻāpana hana e pili ana i nā hiʻohiʻona like ʻole.Ke hoʻohana nei kēia hoʻonā kumu wehe iā J305.Hiki ke ʻike ʻia mai ke kiʻi ʻana o kāna voli hana ʻo 360 ~ 440V, a ua hoʻolako ʻia ka mana mana e kahi pākahi lithium 3.6V maʻamau, no laila pono e hoʻolālā ʻia kahi kaapuni hoʻoikaika.

2. Kumu helu helu
Ma hope o ka hana maʻamau o ka Geiger counter, i ka wā e hele ai ka radiation ma ka Geiger counter, e hana ʻia kahi pulse uila e pili ana, hiki ke ʻike ʻia e ka interrupt waho o ka chip T5L, no laila e loaʻa ai ka helu o nā pulses, a laila hoʻololi ʻia i loko o ka pahu. ʻāpana ana i makemake ʻia ma o ke ʻano helu helu.
I ka manaʻo ʻana he 1 minuke ka manawa hoʻohālike, ʻo 210 CPM/uSv/hr ke ana ʻana, ʻo ka helu pulse i ana ʻia ʻo M, a ʻo ka mea maʻamau i hoʻohana ʻia no ke ana ʻana i ka ikaika o ka radiation he uSv/hr, no laila ʻo ka waiwai e pono ai mākou e hōʻike ʻo K. = M/210 uSv / hola.

3. Kaapuni uila kiʻekiʻe
Hoʻonui ʻia ka pākaukau 3.6V Li-ion i 5V e hāʻawi i ka mana i ka pale COF, a laila hoʻopuka ka pale COF PWM i kahi nalu square 10KHz me kahi pōʻai hana o 50%, ka mea e hoʻoiho i ka inductor DC / DC hoʻonui a me ka back-voltage. nā kaapuni e kiʻi i ka 400V DC e hoʻokaʻawale i ka lako mana i ka paipu Geiger.
