3.4 Loyiha componentlari
Loyiha uchun ishlatilgan componentlar haqida batafsil:
Mikrokontroller: Bu bizning loyihamizning CPU (markaziy protsessor). Biz 8051 oilasining mikrokontrolleridan foydalanmoqchimiz. Mikrokontrollerning turli funktsiyalari quyidagilardan iborat:

1. 
   Klaviaturadan raqamli kiritishni o'qish.
   
2. 
   Ushbu ma'lumotni LCD-ga yuborish, bu loyihani boshqaruvchi shaxs parolni o'qishi kerak.
   
3. 
   Klaviatura yordamida parolni aniqlash va uning to'g'ri parol yoki noto'g'ri parol ekanligini tekshirish va agar kiritilgan parol to'g'ri parol bo'lsa, qadam motorini aylantiring.
   
4. 
   LCD: Biz 16×2 alfanumerik suyuq kristall displeydan (LCD) foydalanmoqchimiz, ya'ni u har biri 16 ta belgidan iborat bo'lgan 2 satrda alifbolarni raqamlar bilan birga ko'rsatishi mumkin.
   
5. 
   Klaviatura: Foydalanuvchi klaviatura yordamida parolni kiritadi. Klaviaturaning turli tugmalari quyidagilardan iborat:
   

1. 
   0 dan 9 gacha.
   
2. 
   Kirish.
   
3. 
   Qochish.
   

6. 
   Teglar: eshikdan kirish tizimi, raqamli kodli qulf, uyga kalitsiz kirish.
   

Ilovalar va afzalliklar:
Ushbu loyihadan ofislarda, kompaniyalarda ham uyda foydalanish mumkin.

1. 
   Bu banklarda xavfsizlikni blokirovka qilish uchun ishlatilishi mumkin.
   
2. 
   Foydalanuvchi o'zi bilan kalitlarni olib yurishi shart emas.
   
3. 
   Foydalanuvshi uchun o`z korxonasi yoki tashkiloti uchun havfsizlik tizimini qurishida ancha havfsiz generatsiyani amalga oshiradi .
   
4. 
   Qo`shimcha sifatida foydalanuvchi o`zininig shaxsiy inestifikatsiyasi hissoblanag biometrik terminlarini kiritishi mumkin albatta qo`shimcha device orqali loyhaga kiritiligandan keyin.
   
5. 
   Shaxsiy malumotlarni boshqa qurilmalarga uzatmaydi va ulardan qabul qilmaydi .
   
6. 
   Dasturiy taminot qismi soft qismidan alohida bo`lganligi sababli havfsizlik darajasi juda yuqori tarzda ishlaydi .
   
7. 
   Soft qismi uchun alohida dastur ishlab chiqilgan bo`lib uni faqat local tarda foydalanish mumkin
   

XULOSA
Ushbu loyhani bajarish davomida qulflanring arxitekturayiv tuzilish va qanday detallardan asosida yig`ilishi barafsil yoritib o`tilgan. Qulflash tizimining mexanik va elektron bo`limlarga bo`linganligi va har bir bo`lim uchun alohida arxitektura ishlab chiqilganligini ko`rishimiz mumkin . Loyha davomida Biometrik xavfsizlik va identifikatsiya jarayonini faqat elektron qulf uchun mo`jjalanganini va u orqali havfsizlik tizimini oson qurish va javobgarlikni kamaytirish uchun ishlab chiqilgan tizimni ko`rishingiz mumkin .RFID texnalogiyasi yordamida biometlik autentifikatsiya jarayonida yuz beradigan kamchiliklarni bartaraf etish va autorizatsiya section ga permission olishni kuzatishimiz, va RFID texnalogiyanini sanot va unga teng qatorda rivojlanayotgan texnik tashkilotlar uchun ancha foydali ekanligini guvohi bo`lamiz . Quydagi keltririb o`tilgan Loyhani texnik qizimlarini batafsil o`rgangandan keyin uning soft qismi uchun kerakli dasturlarni sozlash va assembler muhitida yoki c dasturlsh tili orqali code yozish va generatsiya qilishni ko`rib chiqishimiz mumkin .Code ning texnik qismini tushunish uchun ixohlar yo`qligi sasbabli pasida keltirib o`tilgan batafsil ma`lumot orqali o`zingiz uchun ushbu tizimdan foydalansangiz maqsadga muofiq! Keltirilgan havfsizlik tizmi asosan korxona va tashkilotlar uchun avfzal hissoblanadi ,shaxsiy uy yoki o`zingiz egalik qiladigan buyumlar uchun pastda keltirib o`tilgan biometrik qulflardan foydalanish tavsiya etiladi
