摘要
针对当前无线网络通信在安全可靠方面以及传输效率方面的缺陷,设计了一种新的基于虚拟现实技术的安全智能无线网络通信接口。介绍了无线网络的结构和接口开发平台Visual Studio 2010。所设计的通信接口主要由无线微控制单元、DSP单元和电源模块构成。无线微控制单元以P87LPC764芯片为核心,具有无线网络管理和传输功能,可通过SPI接口和DSP单元实现数据交换。DSP单元主要负责对采集数据进行预处理和识别,将识别结果通过P87LPC764芯片传输至主机。详细介绍了P87LPC764芯片和通信接口硬件连接方案,分析了通信接口设计过程中的关键技术。实验结果表明,所设计接口在保证通信安全、稳定的同时,传输效率高。
Aiming at the security and reliability of wireless network communication and the transmission efficiency,a new secure intelligent wireless network communication interface based on virtual reality technology is designed. The structure of wireless network and interface development platform Visual Studio 2010 were introduces. A communication interface is designed mainly for wireless micro control unit,DSP unit and the power module,the wireless micro control unit with P87LPC764 chip as the core,with wireless network management and transmission function,through the SPI interface and the DSP unit to realize data exchange. DSP unit is mainly responsible for the acquisition of data preprocessing and identification,the identification results will be transferred to the host through the P87LPC764 chip. The hardware connection scheme of P87LPC764 chip and communication interface in detail were introduced,and analyzed the key technologies in the design of communication interface. The experimental results show that the designed interface has high transmission efficiency while ensuring the security and stability of communication.
