Mtengo wa RC522

Mifare RC522 Module imagwiritsidwa ntchito pa 13.56MHz contactless chip card reader, ndi NXP ya "Three Tables" yokhazikitsa pulogalamu ya -voltage, yotsika-yotsika mtengo,{3}}yocheperako,{4}}chipu yowerengera makhadi, zida zanzeru ndi zida zonyamula pamanja zopangidwa ndi njira yabwinoko. MF RC522 pogwiritsa ntchito kusinthasintha kwapamwamba ndi lingaliro lachidziwitso lophatikizidwa kwathunthu mumitundu yonse ya 13.56MHz njira zolumikizirana zopanda kulumikizana ndi ma protocol. Thandizani 14443A zizindikiro zofananira za transponder. Gawo la digito limagwira ISO14443A kupanga ndi kuzindikira zolakwika. Kuphatikiza apo, thandizirani ma algorithms ofulumira a CRYPTO1, kutsimikizira mawu amtundu wa MIFARE. MFRC522 imathandizira MIFARE Series yothamanga kwambiri-osalumikizana ndi anthu,{17}}njira ziwiri{17}zosamutsa deta mpaka 424kbit / s. Monga ophatikizana kwambiri owerenga makadi a 13.56MHz banja latsopano la tchipisi, MF RC522 MF RC500 ndi MF RC530 ndipo pali zofanana zambiri, komanso zimakhala ndi zambiri komanso zosiyana. Zili pakati pa kuyankhulana kwa khamu pogwiritsa ntchito SPI mode, kumathandiza kuchepetsa kugwirizana, kuchepetsa kukula kwa bolodi la PCB ndi mtengo.

Module ya Mifare RC522 ndi njira yolumikizirana yosalumikizana ndi 13.56MHz yowerengera / kulemba khadi yomwe idakhazikitsidwa ndi NXP. Lili ndi izi:

Advanced Modulation and Demodulation Technology:

MF RC522 imagwiritsa ntchito malingaliro apamwamba pakusinthira ndi kutsitsa, kuphatikiza mitundu yonse ya 13.56MHz njira zolumikizirana zopanda kulumikizana ndi ma protocol.

Kutumiza Kwambiri-Kuthamanga Kwambiri Kwambiri:

Imathandizira kulumikizana mwachangu-kwagulu la MIFARE, ndi{1}}kutumiza kwa data molunjika mpaka 424kbit/s.

Multiple Interface Support:

Kutha kugwiritsa ntchito njira zosiyanasiyana zolumikizirana, kuphatikiza SPI, I2C, ndi ma serial interfaces.

Thandizo la algorithm ya encryption:

Imathandizira ma algorithm ofulumira a CRYPTO1 kuti atsimikizire zinthu za MIFARE.

Mapangidwe Ogwiritsa Ntchito Mphamvu Zochepa:

Zomwe zikuchitika panthawi yogwira ntchito ndi 13-26mA / DC 3.3V, zamakono panthawi yopanda ntchito ndi 10-13mA / DC 3.3V, ndipo zamakono mumayendedwe ogona ndi zosakwana 80uA.

Mfundo yogwira ntchito ya gawo la Mifare RC522 imachokera ku 13.56MHz ma radio frequency (RF) kuti alankhule ndi makhadi a Mifare. Module imatumiza ma siginecha opanda zingwe ku RF khadi kudzera mlongoti wake. Mlongoti wa RF khadi akamakwatirana ndikulandira ma siginowa, amasinthidwa ndikusinthidwa ndikusefedwa. Module yoyendetsera magetsi imayendetsanso mphamvu yamagetsi, kuphatikiza kukhazikika kwamagetsi, ma siginecha asanatulutsidwe kumayendedwe osiyanasiyana pa RF khadi. Ikalandira ma siginecha onyamula, khadi lopanda kulumikizana limagwiritsa ntchito ma modulation / demodulation circuitry kuti asinthe / kutsitsa ma siginecha onyamula, ndipo ma sign omwe amakonzedwa amatumizidwa kwa wowongolera khadiyo kuti awawongolere ndikuwongolera. Khadi lopanda kulumikizana likamaliza kusanthula deta, imabwezera ma siginecha onyamula ku MF RC522 kudzera mlongoti wake. MF RC522, nayonso, imayendetsa ma siginechawa kudzera mumayendedwe akeake osinthira / kutsitsa.
 

Module ya Mifare RC522 ndiyoyenera kugwiritsa ntchito njira zosiyanasiyana zoyankhulirana popanda kulumikizana kutengera ISO/IEC14443A, kuphatikiza koma osati ku:

Kutsimikizira:

Amagwiritsidwa ntchito m'machitidwe owongolera mwayi ndi machitidwe opezekapo kuti apititse patsogolo chitetezo.

Malo Okwererako Anthu Onse:

Olemba ntchito pamakina olipira osagwirizana ndi makhadi amabasi, makhadi a metro, ndi zina.

Zam'manja Zam'manja:

Amagwiritsidwa ntchito kusonkhanitsa deta, kutsimikizira zambiri, ndi mapulogalamu ena onyamula.

Mafoni Onse Opanda Contactless:

Perekani njira yogwiritsira ntchito telefoni yosafuna kukhudza thupi.

Smart Meters:

Amagwiritsidwa ntchito powerenga ndi kuyang'anira ma smart metre monga magetsi amagetsi ndi ma mita amadzi.
 

Mbiri Yakampani:

JingZhou Syntek Smart Technology Co., Ltd yomwe idakhazikitsidwa mu 2006, yomwe ili ndi ma module. Timapereka zosankha zingapo komanso makonda omwe amathandizira makasitomala kusankha gawo lomwe liri loyenera pazofunikira zawo zenizeni.Module iliyonse imayesedwa kwambiri kuti iwonetsetse kuti ntchito yabwino, yodalirika komanso yotetezeka.

Chonde khulupirirani kuti potisankha, mukusankha fakitale yomwe imathandizira pempho lanu lokhudzana ndi gawo la RC522.
