Ruzivo rwese rwaunoda kuti uise ruzivo rwekurongedza michina yakabatanidzwa rwese rwuri pano

Kuyedza dunhu rakabatanidzwa nemuchina wekurongedza, chinhu chikuru chinofanira kunge chiri kuyera nzvimbo dzekuedza dzakakosha. Nzira yakajairika ndeyekushandisa kuyedza mudziyo wemagetsi etsoka yega yega uye kupinidza kudzivirira pasi, voltage yekupinda nekubuda, kushandiswa kwesimba uye waveform yekupinda/kubuda, uye mutsauko wemhedzisiro yekuedzwa nematanho edunhu akabatanidzwa, zvinogona kuona kuti dunhu rakabatanidzwa rinofanira kuyedzwa rakajairika.

mu muchina wekurongedza , ma microprocessor emagetsi anoshandiswa zvakanyanya, denderedzwa rakakora remagetsi akabatanidzwa uye amplifier yemagetsi yeswitch IC. Ngationgororei zvakadzama nezveizvi.

muchina wekurongedza kuyedzwa kwedunhu rakabatanidzwa mukiyi yenzvimbo dzekuyedza dzedunhu rakabatanidzwa.

1. Kiyi yenzvimbo yekuyedza dunhu rakabatanidzwa re microprocessor

Kiyi ye microprocessor integrated circuit test point inonyanya kuve VDD power supply side, RESET, RESET, crystal IN vibration signal input, Xor crystal vibration signal output end of the input, output, uye mamwe macircuit.

bvunzo yepamhepo inoyera poindi huru yekupikisa uye kukosha kwevoltage uye yakajairika inogona kutonga kuti dunhu rakabatanidzwa rakajairika;

2. Kiyi yenzvimbo yekuyedza yeIC yekuchinja magetsi

Kiyi yenzvimbo yekuyedza yeIC yekuchinja magetsi inonyanya kuve magumo ekuona kweVc, voltage, current detection input, pulse output, nezvimwewo.

bvunzo yepamhepo yakashandiswa kuyera voltage yedunhu rakabatanidzwa uye kuramba kwepini yega yega, uye wobva waenzanisa nedata pane zvakajairika, senge musiyano mukuru, inofanirawo kuyedzwa ine chekuita nechikamu, chikamu chinoonekwa pasi pemamiriro ezvinhu akajairika, chinogona kutonga kuti dunhu rakabatanidzwa rakakuvara. Mu switch integrated circuit switch tube ndiyo chikamu chikuru, iyo yakavakwa mukati mefirimu gobvu integrated circuit yechubhu yesimba guru kana zvisina kunaka kusava nechokwadi nechubhu yeswitch inogona kuyerwa nekuchinja chubhu c, b, e pakati pekudzivirira mberi nekudzoka kukutonga.

3. Nzvimbo yekuedza yeIC yekusimbisa mashandiro ekushandisa

Kiyi yeIC test point ye operational amplifier inonyanya kukosha kwekupinda nekubuda. Iyi point ye static voltage value yakakwira.

bvunzo, multimeter kusvika kudc voltage, kuyera kukosha kwevoltage inobuda pakati pemagumo ekupedzisira nemagetsi asina simba. Nematweezers esimbi eruoko, tinya magumo maviri ekupinda e operational amplifier (Join the jamming signal), uye tarisa mamiriro ewachi oscillation, pointer ye multimeter ichave ne oscillation yakakura, senge pointer isingafambe, ipapo operational amplifier inenge yakuvara. 4. Bhisikoro remagetsi rakanangana ne integrated circuit point test.

Mumuchina wekurongedza, dunhu nedunhu re555 time base TL494 zvinoshandiswa zvakanyanya. Ngatitarisei zvakananga pfungwa huru dzenzira dzekuyedza dzakatarwa (1) Kuziva dunhu reT494 rakabatanidzwa

kuyedzwa kwedunhu rakabatanidzwa nemuchina wekurongedza kuti uone dunhu rakabatanidzwa T494 nematanho anotevera.

1) Gadzirirai mudziyo. Kuedza macircuit akabatanidzwa kuti musarudze mamwe mabasa, akadai se digital multimeter, mamodheru ane MY68 practical type uye MS820 digital multimeter.

Vanogona kuona frequency ye150 KHZ ne200 KHZ. Vanodawo oscilloscope, wire winding inogadziriswa, nezvimwewo.

2) Kuyerwa kwemafrequency eOscillation. Kutanga, multimeter yescrew kusvika 200 KHZ, kuongororwa kwekutanga T494 oscillation rate (Pane mamwe macircuit akabatanidzwa akadai seari pasi pe200 hz, anogona kugadzirisa giya), kuitira kuti anyatsoita nemazvo. T494 oscillation mu5, uye 6 tsoka, saka mapeni emultimeter uye mutsoka idzi mbiri, vanogona kuona sawtooth wave. Charger uye control circuit ye ​​oscillation frequency ye20 ~ 80 kh, mhedzisiro yekusarudza ine kukosha kwakati, integrated circuit oscillation yakajairika, resistance capacitance value yakarurama.

Kana pasina zviratidzo zvekutenderera, tarisa nzvimbo yekubata, mapeni, uye waya, nezvimwewo. Kana kuyedzazve kuchiri pasi pechiyero chenhamba chedunhu rakabatanidzwa, pane dambudziko.

Kana frequency isingabvumidzwe, zvichireva Rr kana Cr, mamiriro ezvinhu ekuona akakodzera kugadziriswa kana kutsiviwa.

3) Kuyera chiyero chebasa. Yagadzirira oscilloscope, T494 ichaburitsa pini 9, 10, inobatanidza interface yekupinda ye oscillograph, uye ienderere mberi kune 9, 10 tsoka uye mutoro wakayerwa. Pano zvakakosha kucherechedza kuti hapana mutoro wakayerwa, chiyero chebasa hachisi chiyero chakarurama, chinotsauka kubva pakukosha kwedhizaini yekutanga. Tarisa oscilloscope 9, 10 tsoka ye output waveform, panguva imwe chete gadzirisa chiyero chebasa: kudzora chinhu, gadzirisa mubato unodzora kumhanya, ne 0 spin; Iyo charger, gadzirisa kukosha kwekudzivirira kubva pa 0 kusvika 6 tsoka ( Iyo capacitance C, panguva imwe chete gadzirisa) 。 Panguva ino kubva ku oscilloscope inofanira kuona shanduko yechiyero chebasa kubva pa zero kusvika zana muzana.

Kushandiswa kwemuchina wekurongedza kwakajairika kana kuti kwete kwakabatana nekushanda kwakajairika kwemuchina, saka zvakakosha, ndinovimba kuti chinyorwa chino chekuongorora muchina wekurongedza chakabatana chichakubatsira.

Pose panotaurwa nezvemuchina wekuyera uremu, munhu anowana izwi rekuti ''.

Kuti uwane mamwe mazano uye mazano ekugadzirisa zvinobudirira zvekuongorora uremu, tsvaga sarudzo yako paSmart Weighing And Packing Machine.

Mashini ekuyera eSmart Weight Packaging Machinery Co., Ltd akasimba, ari nyore kushandisa, uye ane hushamwari anoshanda, anopa mashini ekuyera emhando yepamusoro ane misoro yakawanda yemhando yepamusoro.
