Mapangidwe a sikelo yamagalimoto ndi njira zochepetsera kulolerana

Tsopano ndizofala kwambiri kugwiritsa ntchito zamagetsimasikelo agalimoto. Pankhani yokonza ndi kukonza zonse za sikelo zamagalimoto amagetsi/weighbridge, tiyeni tilankhule za infotaton iyi ngati ogulitsa mlatho woyezera:

Sikelo yamagalimoto amagetsi imapangidwa makamaka ndi magawo atatu: loadcell, kapangidwe ndi dera. Kulondola kumachokera ku 1/1500 mpaka 1/10000 kapena kuchepera. Kugwiritsiridwa ntchito kwa maulendo awiri ophatikizana a A / D kutembenuka kungakwaniritse zofunikira zolondola ndipo kumakhala ndi ubwino wa mphamvu zotsutsana ndi kusokoneza komanso mtengo wotsika. Pokhazikitsa malamulo amtundu wamtundu wamtundu, zolakwika za sikelo yamagetsi yamagetsi pawokha ndi zolakwika zowonjezera zomwe zimagwiritsidwa ntchito ndizovuta zomwe opanga ndi ogwiritsa ntchito ayenera kulabadira.

Choyamba, njira yochepetsera zolakwika pakupanga ndi kupanga weighbridge yamagetsi:

1. Chitsimikizo cha zizindikiro zaukadaulo za loadcell

Ndilo fungulo lowonetsetsa kuti kuchuluka kwa magalimoto amagetsi kuti asankhe ma loadcell okhala ndi zizindikiro zosiyanasiyana zaukadaulo zomwe zimakwaniritsa zofunikira. Linearity, creep, no-load kutentha koyenera ndi sensitivity kutentha koyenera ndi zizindikiro zofunika loadcells. Pa gulu lililonse la ma loadcell, kuyezetsa kwa zitsanzo ndi kuyesa kwapamwamba komanso kotsika kwa kutentha kuyenera kuchitidwa molingana ndi kuchuluka kwa zitsanzo zomwe zimafunidwa ndi miyezo yoyenera yadziko.

2. Kutentha kokwana kwamagetsi amagetsi amagetsi

Kusanthula kwamalingaliro ndi zoyeserera zimatsimikizira kuti kutentha kwa kukana kolowera kwa amplifier ndi kukana kwa mayankho ndizofunikira zomwe zimakhudza kutentha kwamagetsi amagetsi amagetsi, komanso chopinga chachitsulo chokhala ndi kutentha kwa 5 × 10-6. ziyenera kusankhidwa. Kuyeza kutentha kwakukulu kuyenera kuchitidwa pamtundu uliwonse wamagalimoto amagetsi opangidwa. Kwa mankhwala ena omwe ali ndi kutentha pang'ono kwa kutentha kwapang'onopang'ono, zotsutsana ndi filimu zachitsulo zomwe zimakhala ndi kutentha kwapakati pa 25 × 10-6 zingagwiritsidwe ntchito kubwezera. Panthawi imodzimodziyo yoyezetsa kutentha kwapamwamba, mankhwalawa adagonjetsedwa ndi ukalamba wa kutentha kuti apititse patsogolo kukhazikika kwa mankhwalawa.

3. Zopanda malire za sikelo yamagalimoto amagetsi

M'mikhalidwe yabwino, kuchuluka kwa digito kwa sikelo yamagalimoto amagetsi pambuyo pa kutembenuka kwa analogi kupita ku digito ndi kulemera kwake komwe kumayikidwa pa sikelo yagalimoto yamagetsi kuyenera kukhala yofananira. Mukamayesa kuwongolera moyenera panthawi yopanga, gwiritsani ntchito pulogalamu yapakompyuta yamkati kuti musamalire mfundo imodzi. Werengetsani otsetsereka pakati pa nambala ndi kulemera kwake molingana ndi mzere wowongoka wowongoka ndikusunga kukumbukira. Izi sizingagonjetse cholakwika chopanda mzere chopangidwa ndi sensa ndi chophatikiza. Pogwiritsa ntchito kuwongolera kwa mfundo zambiri, kugwiritsa ntchito mizere yowongoka ingapo kuti mufanane ndi mapindikira bwino kumachepetsa cholakwika chopanda mzere popanda kuwonjezera mtengo wa Hardware. Mwachitsanzo, sikelo yamagetsi yamagetsi yokhala ndi kulondola kwa 1/3000 imatenga ma calibration a 3-point, ndipo sikelo yagalimoto yamagetsi yokhala ndi kulondola kwa 1/5000 imatenga ma 5-point calibration.
