Chii chinonzi Automotive Power Systems

Masimba emagetsi masisitimu anosanganisira maviri ekutanga marudzi: emagetsi magetsi emagetsi uye emagetsi emagetsi inverters. Iyo yekutanga inoreva kuomesesa masisitimu uye zvishandiso zvinopa simba kune akasiyana midziyo yemagetsi mumotokari, zvinosanganisira injini yekudzora zvikamu, mu-mota varaidzo masisitimu, mwenje, midziyo yekutaurirana, uye masisitimu ekufambisa. Iwo ekupedzisira, emagetsi emagetsi inverters, anoshandura yakananga ikozvino (DC) kubva mubhatiri remotokari kuita alternating current (AC) simba, zvichiita kuti ive yakakodzera kune zvemagetsi zvinoda AC simba.

Magetsi emagetsi emagetsi akakosha kana midziyo yemagetsi ichida simba reAC nepo bhatiri remota richipa DC simba. Vanogonesa kushandurwa kwesimba reDC kubva mubhatiri kuita simba reAC, kufambisa kushanda kwemidziyo yakaita semalaptops, machaja, uye anotakurika magetsi mukati memotokari. Paunenge uchisarudza inverter yemotokari yemagetsi, zvakakosha kuti utarise zvinhu zvakaita seinodiwa simba remagetsi, kubuda kwemagetsi, uye frequency, semhando dzakasiyana dzinopa akasiyana hunyanzvi.

Kunzwisisa Automotive Power Systems

Masisitimu emagetsi emotokari akakosha pakupa masimba akasiyana siyana emagetsi uye zvikamu mukati memotokari, senge injini yekudzora unit (ECU), masisitimu evaraidzo, uye masisitimu ekufambisa. Kubudirira kwesimba rekutonga mune aya masisitimu kwakakosha pakushanda kwemotokari yakavimbika uye kunyaradza kwevatyairi. MaPCB akakosha pakubata aya masisitimu emagetsi nemazvo. Heano maitiro aya masisitimu uye basa rePCBs:

1. Engine Control Unit (ECU)

Basa: ECU ndiyo pfungwa yehurongwa hwekutarisira injini yemotokari. Inotarisa uye inodzora zvinhu zvakasiyana-siyana zvekushanda kweinjini, zvakaita sekupinza mafuta, nguva yekupisa, kuburitsa utsi, nezvimwewo.

Kuwanikwa Kwemagetsi: ECU inowanzoda kuti magetsi ashande zvakanaka uye akarongeka. Inowanzo batanidzwa kune simba guru remotokari kuburikidza netambo yekubatanidza waya.

Basa rePCB: MaPCB anoshandiswa mukati meECU kutarisira nekuparadzira magetsi zvinobudirira. Ane zvinodzora magetsi, maseketi ekudzivirira, nezvimwe zvikamu kuti ave nechokwadi chekuti magetsi anowanikwa zvakanaka kune ma microcontroller nemasensa eECU. MaPCB anopawo kubatana kunodiwa kune zvikamu zvakasiyana-siyana mukati meECU.

2. Varaidzo Systems

Basa: Masisitimu ekuvaraidza mota anosanganisira zvikamu zveaudio nemavhidhiyo, zvakaita sema head units, amplifiers, speakers, uye displays. Masisitimu aya anopa varaidzo neruzivo kune vafambi.

Kupa Simba: Masisitimu ekuvaraidza anowanzo shandiswa nemagetsi emotokari. Semuenzaniso, chikamu chikuru chemotokari chakabatana nemagetsi makuru, nepo ma amplifiers anogona kunge aine simba rawo rekugovera.

Basa rePCB: PCB dzinoshandiswa muzvikamu zvesystem yekuvaraidza pakugadzirisa masaini, kuwedzera simba, uye kudzora. Dzinoitawo basa mukutonga kwesimba, kusanganisira kudzora magetsi nekudzivirira. PCB dziri muzviratidziro nemusoro dzinobatsira kudzora mabasa akasiyana-siyana uye ma interfaces.

3. Navigation Systems

Basa: Masisitimu ekufambisa anopa nhungamiro neruzivo rweGPS panguva chaiyo kune vatyairi. Anosanganisira maGPS receiver, display, uye control units.

Simba: Masisitimu ekufambisa anoshandiswa nemagetsi emotokari. Anoda simba rakagadzikana kuti GPS ishande uye kuti display ishande zvakanaka.

Basa rePCB: MaPCB ari mu navigation systems anotarisira kugoverwa kwesimba uye kugadziriswa kwesimba, zvichiita kuti GPS receiver iwane simba rakachena kuti inyatsoteedzera nzvimbo. Pamusoro pezvo, maPCB anotarisira kugadziriswa kwedata reGPS uye ma control interfaces ekushandisana kwevashandisi.

Basa rePCB muKugadzirisa Masimba Sistimu Zvinobudirira

• Voltage Regulation: MaPCB anowanzo batanidza magetsi ekudzora kuti ave nechokwadi chekuti zvikamu zvemagetsi zvinogashira yakagadzikana uye chaiyo voltage level, kudzivirira kukuvadzwa kubva kumagetsi ekuchinja.
• Dziviriro Denderedzwa: MaPCB anogona kusanganisira maseketi ekudzivirira, akadai semafuse uye overvoltage dziviriro, kuchengetedza zvinhu zvemagetsi kubva pakukanganisa kwemagetsi kana masurgery.
• Signal Routing: MaPCB anopa hukama hunodiwa uye nzira dzezviratidzo uye simba rekuyerera pakati pezvikamu zvakasiyana, zvichiita kuti kutaurirana kusina musono uye kutonga.
• Dhizaini Yakaumbika: MaPCB akagadzirwa kuti ave compact, achibvumira kushandiswa zvakanaka kwenzvimbo mukati memotokari yemagetsi zvikamu.
• Customization: MaPCB anogona kugadzirwa kuti asangane neiyo chaiyo simba uye chiratidzo chinodiwa chega yega mudziyo wemagetsi, kuve nechokwadi chekushanda kwakakwana.

Automotive Power Inverters (Auto Power Supply)

Magetsi emagetsi emotokari, anozivikanwawo semagetsi emagetsi emotokari kana DC kune AC magetsi inverters, zvinhu zvakakosha zvinoshandura yakananga ikozvino (DC) magetsi emagetsi kubva mubhatiri remotokari kana system yemagetsi kuita alternating current (AC) simba. Iri simba reAC rakashandurwa rinogona kushandiswa kushandisa zvakasiyana siyana zvemagetsi uye midziyo inowanzoda simba reAC. Heano akakosha maficha emagetsi emagetsi inverters:
