基于RFID车辆信息交换系统的射频模块设计

Design of RF module based on RFID vehicle information exchange system

基于RFID车辆信息交换系统,给出了系统中射频模块的参数选择、节点设置和软硬件设计方法,同时给出了硬件各模块的选择、上位机工作方式以及下位机控制程序的设计方法。为了保证对系统的精准性数据保护,设计中采取了CRC方法和LRC方法,并确定了传输协议。

In this paper, a RF module, based on RFID vehicle information exchange system, is designed. The parameters selection, nodes setting and hardware and software design method in the system are given, and at the same time, the hardware module selection, the operation way of the host computer and the design method of the control program of the console computer are presented. In order to ensure the system accuracy and protect the data, CRC and LRC are adopted in the design scheme, and the transfer protocol is decided.
