摘　　要：该文根据应答器的工作需求,基于嵌入式系统的设计理念,提出了一种便携的无线编程器的研究方法。硬件设计采用FPGA+ARM实现,调制和解调单元由FPGA来实现,中央控制单元由ARM来实现。软件基于μC/OS-Ⅱ技术实时多任务设计,实现了系统实时、安全、高效的要求。采用RS-232和蓝牙两种通信模式,方便用户的编程操作及数据传输。并通过LCD显示和键盘操作,很好地实现了人机交互。通过示波器观察到输出波形符合设计要求。Based on the needs of balise and the design concepts of embedded system,this paper proposes a new method of portable wireless programming.In this method,hardware design is completed by using FPGAARM.Specifically,the modulation and demodulation unit and the central control unit respectively adopt the principle of FPGA and ARM.Meanwhile,software design achieves the requirements of real-time,security and efficiency by useing μC/OS-Ⅱ technology which is a real-time and multi-task design.In addition,it uses RS-232 and Bluetooth communication mode to facilitate program operation and data transmission.Moreover,the adoption of LCD display and keyboard shows a good effect of human-computer interaction.Finally,the output waveforms observed through the oscilloscope meet the design requirements.
