电子标签销码器的设计
摘要：在掌握了射频识别技术，研究了ATC2051单片机的工作原理和指令系统的基础上，进行了硬件和软件设计，整个系统以Keil Uvision2为开发平台，设计了程序流程，采用了汇编语言编写程序代码，电子标签销码器设计采用C2051单片机、NE5等芯片，运用的是智能控制、频率合成、高频小信号检测等技术。软件设计中主要应用单片机的中断和定时功能，利用P3端口的第二功能，来控制功率、发射、检测以及蜂鸣等，实现软件和硬件的结合，从而完成销码器的设计。 关键词：单片机；射频识别；销码器
The Design of Electronic Tag Pin Code
Abstract:Based on mastering the radio frequency identification technology and studying the working principle of ATC2051 chip microcomputer and command system, we do the hardware and software design.The electric tag code remover design adopts the C2051 chip microcomputer,NE5 etc chip. It applies the technologies such as intelligent control, frequency combination, high frequency micro-signal detection and so on. The whole system takes Keil Uvision2 as the developing platform. We design the procedure flow and make use of the assembly language compile procedure code. In the software design, we mainly apply the chip microcomputer interrupt and timing function. We use the second function of P3 port to control the power, transmit, detection, buzzing etc. That achieves the combination of the software and hardware to complete the design of the code remover.
