车载NFC标签近场通信应用

Car NFC Tag for Near Field Communication Application

探讨了NFC(Near Field Communications,近场通信)功能在汽车上的应用,通过对车载NFC的应用场景的分析,提出在现有车载电子的基础上加装NFC标签模块而不是NFC读写器模块就可以实现车载NFC的功能.利用NFC标签作为桥梁来实现智能手机与车身控制器之间的半双工近场通信.并对方案进行设计验证,NFC标签在汽车上的应用过程简单,成本便宜,易于实现,对于实际的工程应用具有指导作用和参考价值.

This article discussed the application of car NFC（ Near Field Communications） function,and analyzed the on- board NFC application scenarios. It proposed to install of NFC tag module which instead of NFC reader module which can realize the on- board NFC function based on the existing vehicle electronic. It uses NFC tag as a bridge to realize the half duplex communication between the smart phones and the vehicle body control module. The author had designed and made a NFC tag demo board to verify the concept. The application of car NFC tags is simple,and the cost is cheap and it is easy to be implemented. There is a good instruction and reference value for the practical engineering application.
