摘要
本文介绍以双频相干相位方式进行编码和以BCD码加校验码方式进行字符组合的磁卡读写器的软件、硬件设计。该磁卡读写器已用于磁卡电子锁和磁卡安全门系统。
The software and hardware design of the PP-1 magnetic card read write device are introduced in this paper, which adopted the dual-frequency coherent phase means to coding and adopted BCD code appended check code means to compose character. The device has been used in the system of magnetic card electronic lock and safety door.
