物联网工业串口转WiFi模块 无线路由WiFi模块的选型
2022-07-28 04:28:00 【博晶网络】
伴随着物联网的发展,最初的两个机器之间通过硬件直接通信的物理层到通过硬件地址再局域网中进行通信的数据链路层已经远远不能满足于现代人们生活以及各行给业生产的需求。逐渐结合高性能,高质量的网络层和应用层。实现智能终端数据采集,数据传输,数据上传和无线上网,WiFi远程控制等功能。在物联网市场上,从成本,功耗,体积而言,无线物联网WiFi模块传输还是以串口WiFi模块为主。
串口转WiFi模块是一种基于UART接口的嵌入式模块,它符合WiFi无线网络标准,内嵌于IEEE802.11协议栈和TCP/IP协议栈,可以实现用户串口或TTL电平数据到无线网络的转换。串口型WiFi模块的工作方式为传输式和命令式。
现在小编要谈的是市面上多线程多处理的路由串口WiFi模块。随着对现场数据实时监测,远程控制,数据上传,视频传输,音频传输等需求量增大。路由串口WiFi模块逐渐被应用到各行各业。核心CPU带Linux系统,可同时处理多线程处理复杂指令。有多路串行UART接口,传输指令的时多个指令同时发出,并快速地响应同时处理。
BOJINGnet推出的RMS7688A模块核心CPU带有Linux系统多线程处理器的路由串口WiFi模块,兼容802.11b/g/n,是低成本,低功耗的无线AP解决方案,集成802.11n MAC/BB/PA/LAN, 带宽比较大,能同时运营比较复杂的指令。具备3路串口可以同时跟多个服务器对接,3路串口可以同时同一环境下快速地监测温度,速度,灯控等数据指令传输。在很大程度上提高效率,降低成本。RMS7688A串口转WiFi模块支持AP/AP client /路由器/中继模式,在IOT中被广泛应用。如:工业控制、有线转WiFi、4G转WiFi、吸顶AP、4G路由器、无线音箱、无线视频传输、无线存储扩容、无线图传、数据透传、工业路由器、wifi打印机等。
