Wolemba: Smartweigh-Multihead Weighter
Chojambulira cha digito cha multihead weigher chomwe chapangidwa mu pepalali ndi chida chowongolera chowongolera chotengera mphamvu ya resistor strain mphamvu komanso kapangidwe ka chip kamodzi monga chinsinsi chowongolera. Mtundu wodziwikiratu ndi 0-10kg, ndipo muyeso wolondola ndi±2g, mawonekedwe amadzimadzi amadzimadzi amadzimadzi amawonetsa zidziwitso zakuyezetsa kolondola, kuphatikizanso, chidziwitso chazomwe zayezetsa zitha kutumizidwa pakompyuta yamagetsi kuti iwonetse zambiri malinga ndi kulumikizana kwa serial. Pulogalamu yamakina imakhala ndi mawonekedwe olondola kwambiri, mawonekedwe okhazikika komanso ntchito yosavuta. Chithunzi cha chimango cha multihead weigher design scheme chikuwonetsedwa mu Chithunzi 1 pansipa: 1. Mfundo yoyendetsera dera la hardware 1.1. The weight sensor resistor The strain force type weight sensor imapangidwa ndi zigawo zambiri zofunika monga resistani strain gauges, polyurethane elastomers ndi mabwalo oyendera magetsi.
Polyurethane elastomer imayambitsa kupunduka kwa zotanuka pansi pa mphamvu yakunja, kotero kuti kukana kwamphamvu komwe kumalumikizidwa pamwamba pake kumayambitsanso kupunduka. Pambuyo pakuwonongeka kwa tsinde la kukana, mtengo wake wokana udzasintha (kukula kapena kutsika), ndiyeno kudzera muyeso yolondola. mphamvu yakunja kukhala chizindikiro chamagetsi. Dongosolo lamagetsi oyesera likuwonetsedwa mu Chithunzi 2, ndipo kukana kwa choyezera chamagetsi kumasinthidwa kukhala mphamvu yamagetsi yogwira ntchito. Chifukwa mlatho wa Wheatstone uli ndi zabwino zambiri, monga kutha kuletsa kuvulaza kwa kusintha kwa kutentha, kupondereza mphamvu ya mbali, komanso kuthana ndi vuto la chipukuta misozi, mlatho wa Wheatstone wakhala ukugwiritsidwa ntchito kwambiri polemera. masensa. ntchito.
Sensa yolemera nthawi zambiri imakhala ndi mizere inayi ya I / O, ndipo kukana kotulutsa nthawi zambiri kumakhala 350Ω, 480Ω, 700Ω, 1000Ω. Malo olowetsamo nthawi zambiri amalipirako chifukwa cha kutentha ndi kumva. Chothandizira cholowera chidzakhala 20-100Ω kuposa chotulutsa. Chifukwa chake, ma terminals a I / O amatha kusiyanitsa poyesa kukana ndi ma multimeter a digito. 1.2. Chidziwitso cha data chotulutsa cholumikizira chamtundu wa amplifier sichiri cholimba (mu dongosolo la mV kapena ngakhale μV), ndipo nthawi zambiri chimatsagana ndi phokoso lalikulu. Pachidziwitso choterechi, sitepe yoyamba munjira yolumikizira magetsi nthawi zambiri imakhala kusankha chokulitsa chida kuti choyamba chikulitse chizindikiro chaching'ono cha data.
Magetsi amplifier a zida ali ndi mphamvu zokanira zofananira kuposa ma siginolo op amps osavuta. Cholinga chovuta kwambiri choonjezera sikuli phindu la phindu, koma kungowonjezera kukhazikika kwafupipafupi kwa dera loperekera mphamvu. Pamapangidwe awa, chokulitsa chida chimatenga mawonekedwe a OP07 amplifier atatu ogwira ntchito.
Monga momwe tawonetsera mu Chithunzi 3. Pamene R1 = R2, R3 = R4, Rf = R5, phindu lopindula la dera lamagetsi ndi: G = (1 + 2R1 / RG1) (Rf / R3). Zitha kuwoneka kuchokera ku chiŵerengero cha chilinganizo kuti kusintha kwa mtengo wopindula wa dera loperekera mphamvu kumatha kutsirizidwa mwa kusintha mtengo wotsutsa wa RG1.
1. 3. A/D kutembenuka kwamagetsi opangira magetsi A/D converter amasankha electronic scale-specific integrated icHX711, yomwe ndi 24-bit A/D converter Integrated ic yopangidwa mwapadera kuti ikhale yolondola kwambiri sikelo yamagetsi. Poyerekeza ndi ma IC ena ophatikizika amtundu womwewo, IC yophatikizika imaphatikiza mabwalo ozungulira omwe amafunikira ma IC ena ophatikizika amtundu womwewo, kuphatikiza magetsi owongolera osinthika, oscillator wotchi ya digito, ndi zina zotero. Lowetsani chosinthira kuti musankhe njira yachitetezo A kapena njira yachitetezo B mwakufuna kwanu, ndipo cholumikizira chowongolera chamkati chokhala ndi phokoso lotsika chimalumikizidwa pakati pa ziwirizi.
Wowongolera omwe amatha kuwongolera amapeza mtengo wachitetezo cha njira A ndi 128 kapena 64, ndipo chiwongola dzanja chokwanira chosiyanitsira ma siginecha amtundu wamakina amplitude mtengo motsatana.±20mV kapena±40 mv. Njira yachitetezo B ndi phindu lokhazikika la 32, ndipo mphamvu yofananira yolumikizira ma siginecha ikugwira ntchito.±80mv. Njira yachitetezo B imagwiritsidwa ntchito kuyang'ana magawo akulu a pulogalamu yamakina kuphatikiza batire yowonjezedwanso.
Dongosolo lopanga izi limatsogolera kutulutsa kwa amplifier kwa zida zolowera panjira yachitetezo A kuti ayesere chizindikiro chosiyana cha analogi, multihead weigher1.4, kapangidwe ka chip chimodzi ndi mawonekedwe olumikizirana mawonekedwe amtundu umodzi amasankha AT89C51 Integrated ic, ndi mawonekedwe olumikizirana ndi makiyi ntchito, madzi galasi anasonyeza chophimba ndi kompyuta pakompyuta anasonyeza 5. HX711 siriyo kulankhulana mzere amatsogolera single-chip kamangidwe P1.0 ndi P1.1 madoko. Yankho likapangidwa ndi makina ang'onoang'ono a single-chip, chidziwitso choyezera deta chimatumizidwa pazithunzi za LCD.
Kuphatikiza apo, kangapo za chidziwitso cholondola cha data choyezera chimatumizidwa ku kompyuta yamagetsi kuti iwonetse zambiri malinga ndi kulumikizana kwa serial.
