Zingaphi iindlela zovavanyo ezikhoyo zePCB zombane zombane?

Ukuvavanya amacandelo ombane we-PCB yinxalenye ebalulekileyo yovavanyo lwe-PCB. Ke, zingaphi iindlela zovavanyo ezikhoyo zePCB zombane zombane?

1.Uvavanyo lwekhoyili oluqhelekileyo

Ukuvavanya i-coil, ibhuloho yedijithali ingasetyenziselwa ukuvavanya i-inductance kwi-intanethi. Ngenxa yokusebenza rhoqo kweikhoyili ye-inductorihlala ingekho phantsi, i-inductance inokuvavanywa kwi-frequency engaphezu kwe-10kHz.

2. Uvavanyo lwekhoyili yeTransformer

Ngokuvavanya ixabiso le-inductance D le-coil engundoqo ye-transformer, sinokugqiba ukuba ngabaisitshintshiine-inter-turn short circuit. Indlela ethile yile: setha ibhuloho yedijithali kwi-0.3V okanye ngaphantsi, i-10kHz okanye ngaphezulu, kwaye ulinganise ixabiso le-D le-coil inductance engundoqo. Ukuba ixabiso le-D likhulu kune-0.1, kugwetywa ukuba i-transformer yonakaliswe kwaye ayikwazi ukusetyenziswa.

3. Ukufunyanwa kwezixhobo zeHolo

Izinzwa zeholo zifumaneka kumbane omnye kunye nonikezelo lwamandla amabini, kunye nohlobo lwemveliso yangoku kunye nohlobo lokuphuma kombane. I-sensor yonikezelo lwamandla enye ayiboni okwangoku, kwaye isignali yokuphuma ngokubanzi i-1/2 yonikezelo lwamandla omnye. Ukuba okwangoku ngu-0, imveliso yesignali itenxa kakhulu kwixabiso eliphakathi. I-sensor inokuvavanywa ngokobungakanani ukufumanisa ukuba i-sensor yeHolo yonakele. Isivamvo seHolo esineziphumo zonikezelo lwamandla amabini 0 i-voltage xa ​​iva i-0 yangoku; xa ivakalelwa ngaphandle kwe-0 yangoku, i-positive, i-negative kunye nobukhulu bombane ophumayo utshintsha kunye nobukhulu kunye necala le-current induced.

4. Uvavanyo lweereyilayi

Iimpazamo eziqhelekileyo zokuhanjiswa zibandakanya ukuqhawulwa kwekhoyili, abafowunelwa abangavaliyo, ukuchasana noqhagamshelwano oluphezulu, kunye noqhagamshelwano olutshisiweyo. Indlela efanelekileyo yokuvavanya ukuba i-relay iyinto eqhelekileyo kukunika amandla i-relay, ukusebenzisa i-voltage elinganisiweyo kwikhoyili, uze uvavanye ukuqhubeka koqhagamshelwano.

Ngemibuzo yemveliso, nceda ujonge iiphepha lemveliso, nawe wamkelekile ukubaQhagamshelana nathingokusebenzisa iinkcukacha zoqhagamshelwano ezingezantsi, siya kukuphendula phakathi kwama-24.
