基于人体通信的信息交互系统设计

针对穿戴式设备之间的互联互通问题,研究并实现了基于人体通信技术的信息交互系统.考虑到穿戴式设备的应用场景,设计了人体通信双向通信的MAC协议;为了提高系统的通信效率,定制了人体通信传输帧结构;为了降低系统功耗,设计了系统的3种工作模型.实验结果表明,该系统能够快速完成信息交互,其实时数据率达到200 kbit/s,误码率亦趋近10-8.为IEEE 802.15.6标准MAC协议的实现奠定了良好基础,将进一步推动人体通信技术的发展与应用.

Design of interactive information system based on the Human Body Communication

In view of the connectivity problem among wearable devices, studying and implementing the interactive information system based on the human body communication. Considering the application scenarios of the wearable device, designing the bidirectional communication MAC protocols on the human body communication; In order to promote the communication efficiency of the object, constructing one kind of transmitting frame structure about human body communication; To reduce the power consumption of the system, designing three types of models for the system; The results are proved that the scheme could finish information interaction immediately. Its data rate arrives at 200 Kbps, and the bit error rate is 10-8.At the same time, this paper works laid a good foundation for 802.15.6 standard realization of MAC protocol, and it is further promoting the development of the technology and application on the human body communication.
