【应用】UMS无线收发器CHR2270-QRG应用于汽车OBU,专用于5.8GHz近程通信,通信距离较长且速率高
汽车已经成为大家出行必不可少的交通工具,在进出高速路口由以前的窗口停车缴费,到现在的的车辆行进途中,实现车辆识别,电子扣费,这里就涉及到ETC系统,OBU是放在汽车前端的插卡设备,建立与RSU之间微波通讯链路,从而实现不停车扣费,而OBU与ETC系统的无线交互,我们推荐UMS的双向收发器CHR2270-QRG,我们先看一下它在OBU的大致应用框图:

实物图
车辆经过ETC系统的专用车道时,车辆前端的OBU设备会读取标签数据并通过CHR2270-QRG发射微波,门架上的RSU也会发射微波,在对应频率的频段中实现短距离快速通讯,现在我们看下它在其中的优势,CHR2270-QRG包括双向传输的所有射频功能和控制器的数字接口专用于5.8GHz的近程通信,这个频率通信距离较长且速率高,抗干扰能力也比较强,在SB_out和SB_CPT输出上提供选择性唤醒信号,避免过早唤醒,而且在空转模式下功耗只有3.8μA,可以大大延长这类电池供电产品的使用年限。
综上所述,UMS推出的无线收发器CHR2270-QRG应用于汽车OBU,不仅传输信号性能优异,而且功耗低,非常适合汽车车OBU的应用。
