Chida choyezera chakutali cha laser methane JJB30

1, Chidule
Chida choyezera cha methane chakutali cha laser chimapangidwa ndi magawo awiri: makina otumizira ndi kulandira kuwala kwa laser ndi makina ogwiritsira ntchito zizindikiro. Makina otumizira ndi kulandira kuwala kwa laser ali ndi mipiringidzo iwiri ya laser. Chimodzi ndi laser ya infrared yodziwira mpweya, ndipo china ndi laser yofiira/yobiriwira yowoneka bwino yomwe imagwiritsidwa ntchito posonyeza komwe ikupita komanso mtunda woyezera. Wogwiritsa ntchito akakanikiza batani la "MALIZIRO", laser yosaoneka ya infrared ndi laser yofiira/yobiriwira yofanana ndi cholembera chosonyeza kuwala zimayamba kugwira ntchito mosalekeza. Laser ya infrared yomwe imatulutsidwa ndi gawo lotumizira imayamwa ndi mpweya wa methane ikadutsa mu mpweya woyesera, ndipo gawo lina la kuwala limabwereranso kumapeto kolandira kudzera mu zopinga wamba (monga: njerwa, konkire, udzu, ndi zina zotero). Kuwala komwe kumabwezeretsedwa kumapeto kolandira kumasonkhanitsidwa ndikusinthidwa kukhala chizindikiro chamagetsi ndikutumizidwa ku dongosolo logwiritsira ntchito zizindikiro. Dongosolo logwiritsira ntchito zizindikiro limazindikira ngati pali kutuluka kwa mpweya m'malo oyesedwa pozindikira mphamvu ya kuyamwa kwa kuwala kwa laser ndikuwonetsa kuchuluka kwa mpweya mu chipangizo choyezera chakutali mu mayunitsi a ppm-m kapena %vol. Laser yowoneka nthawi imodzi imayesa mtunda kuchokera pa chipangizocho kupita pamalo owunikira ndikuwonetsa kuchuluka kwa mpweya nthawi yomweyo. Chifukwa cha mfundo yakuti mpweya (monga methane) umayamwa mphamvu pa mafunde enaake a laser, mankhwalawa amangoyankha ku mpweya winawake (monga methane) ndipo sangayambitse ma alarm abodza chifukwa cha kusokonezedwa ndi mpweya wina, fumbi, nthunzi ya madzi, ndi zina zotero, zomwe zimapangitsa kuti kuzindikira kukhale kolondola komanso kupewa kuyeza kolakwika. Chipangizo chodziwira ndi kuchenjeza cha JJT4-1000 methane ndi carbon monoxide chimagwiritsidwa ntchito kwambiri pozindikira pansi pa nthaka.
2, Mawonekedwe
1. Chogulitsa chotetezeka mkati mwake;
2. Yosankha mpweya monga (methane), yosakhudzidwa ndi mpweya wina uliwonse, nthunzi ya madzi, ndi fumbi;
3. Mtunda wa telemetry ukhoza kufika mamita 60;
4. Imabwera ndi ntchito yowonetsera mtunda;
5. Kakang'ono kukula, kopepuka kulemera, kosavuta kunyamula;
6. Kugwiritsa ntchito mphamvu zochepa, zomwe zimatha kugwira ntchito kwa nthawi yayitali;
7. Kukana kugwedezeka bwino, kukana madzi, komanso kukana fumbi;
8. Liwiro loyankha mwachangu, miyeso yochuluka, kulondola kwambiri kwa miyeso;
9. Njira yotumizira deta yomwe ingagwiritsidwe ntchito malinga ndi zosowa za makasitomala.
