Description

一种WIFI音频传输模块
技术领域
本实用新型涉及一种驱动模块，尤其涉及一种WIFI音频传输模块。 
背景技术
目前蓝牙是常用的音乐等文件的传输无线方式。 
Wi-Fi的私密性和抗干扰能力不及蓝牙，但是WI-FI的优势在速度和网络化的能力。以现在主流的是Wi-Fi标准802.11g和802.11n为例，802.11g提供54Mbps的传输速率，802.11n提供300Mbps的传输速率，都已远远超出CD级音质所需带宽，在传输音乐的同时还能满足视频传输和网络浏览的需求。 
Wi-Fi可两个设备直连，也能通过无线路由组成网络。能组成网络正是WIFI相比蓝牙最大的优势。以现有的iPad为例。通过WIFI连接，iPad通过Air Play连接音箱，能够同时对局域网中所有在网音箱放声，而且可对不同音箱播放不同声音，于此同时还能满足网络浏览的需求，这是蓝牙所不具备的。 
发明内容
本实用新型专利通过使用WIFI实现音频传输，使得音响设备可以通过WIFI接入互联网进行云端播放，并且可以使用手机、计算机等带WIFI设备直接将音频信号传输。 
WIFI音频传输模块，包括CPU芯片、Flash芯片、SDRAM芯片、数据接口单元、外部数据接口连接器、无线信号收/发开关，其中Flash芯片、SDRAM芯片、数据接口单元、外部数据接口连接器、无线信号收/发开关分别与CPU芯片相连，CPU芯片具有无线处理模块，其特征在于，所述数据 接口单元包括以太网接口和串口，外部数据接口连接器通过I2S、USB接口连接到用户端，所述无线信号收/发开关相连有WIFI天线。 
本实用新型提供的驱动模块解决了蓝牙或者其它频率传输音频的局限性，主要体现在如下方面：1、高带宽，本专利使用带宽150Mbps，可以直接传输高保真无线音频信号；2、远距离，可以在400米距离实现音频传输；3、I2S标准硬件接口，I2S接口可以直接传送音频信号，无需音频解码。 
附图说明
图1是本实用新型的硬件结构图； 
图2是本实用新型的模决结构图。 
具体实施方式
如图1所示，硬件部分主要包括CPU芯片、Flash芯片、SDRAM芯片、数据接口单元、外部数据接口连接器、无线信号收/发开关，其中Flash芯片、SDRAM芯片、数据接口单元、外部数据接口连接器、无线信号收/发开关分别与CPU芯片相连，CPU芯片具有无线处理模块，所述数据接口单元包括以太网接口和串口，所述无线信号收/发开关相连有WIFI天线，外部数据接口连接器通过I2S、USB接口连接到用户端。 
本项目主要应用无线通信原理，在802.11n的技术基础上，完成的研究，形成基于802.11n的I2S无线产品。整个项目模块结构图如图2所示。 
CPU采用360MHz CPU(MIPS架构)，运行Linux操作系统，TCP/UDP协议栈，AT指令集和应用程序。 
MIPS是世界上很流行的一种RISC处理器。MIPS的意思“无内部互锁流水级的微处理器”(Microprocessor without interlocked piped stages)，其机制是尽量利用软件办法避免流水线中的数据相关问题，目前该模块使用一颗360Mhz的MIPS CPU用于处理WIFI协议栈，强劲的处理能力能够使该模块运行于独立的AP模式，区别于目前市面上的模块。该模块支持完整的路 由功能，网卡模式，WIFI直连模式这些独特的WIFI组网技术，这些先进的功能在本实用新型中得到新组合和优化。 
同时，该MIPS集成了WIFI MAC处理器和2.4G的收发器，用户处理WIFI信号的上下变频，放大，并预留丰富的外围接口，汉枫电子在此基础上进行了改进：将原来用于调试的UART接口用户数据传送，使得能够用于基于物联网数据采集和低端MCU数据通信，使其能够工作在非常弱小的上位机领域中，比如传感器，工业数据监控等等，I2S信号通路经过修改驱动，使得可以透明传输音频流信号，可以广泛使用WIFI音频领域。 
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本实用新型保护的范围之内。
