Xa kuziwa kwizikali, wonke umntu akayi kuziva engaqhelekanga. Ziluncedo kakhulu ekulinganiseni ubunzima kubomi bemihla ngemihla. Iindidi eziqhelekileyo zezikali zibandakanya izikali zekhitshi ze-elektroniki, izikali zomzimba we-elektroniki, kunye nezikali zomzimba ezinomatshini. Ke, yeyiphi imixholo ephambili ekufuneka ihlolwe kwaye zeziphi iimvavanyo ekufuneka zenziwe xa kuhlolwa iimpahla? Siyathemba ukuba le mixholo iluncedo kuwe!
Umgaqo wokusebenza
Xa into ibekwe kwisikali, uxinzelelo lusetyenziswa kwi-sensor, ephazamisayo, ebangela utshintsho kwi-impedance. Ngexesha elifanayo, i-voltage yokuvuselela isetyenziselwa ukutshintsha kunye nokukhupha umqondiso owenziweyo wokutshintsha. Isignali ikhuliswe yisekethe yokukhulisa kunye nemveliso kwi-analog-to-digital converter. Guqula iisignali zedijithali eziqhubekeke ngokulula kwaye uzikhuphele kwi-CPU yolawulo lokusebenza. I-CPU ikhupha esi siphumo kwimonitha esekwe kwimiyalelo yebhodibhodi kunye neenkqubo. De kube esi siphumo sibonisiwe.
Ukuhlelwa kwezikali
Kwinkqubo yokuhlola, sisebenzisa ubukhulu becala izikali zasekhitshini zombane, izikali zomzimba zombane, kunye nezikali zomzimba ezingoomatshini
