基站天线淋雨试验解决方案

方案背景

随着5G时代的到来，各级市县城市甚至是村都会需要安装大量的基站天线，而作为户外用的工具，需要特别考虑雨天情况的影响。过去，天线一旦进水，会造成系统的覆盖范围变小，系统的接收灵敏度变坏等影响。

户外骑行活动越来越受到人们的喜爱，对这项运动的工具也越来被厂商重视。特别是自行车灯，作为夜间行车的“眼睛”，车灯的质量被格外重视。除了照明质量以外，车灯的防雨的能力也是众多消费者心里的痛点。为了提高车灯的防雨能力，需要通过不断的淋雨测试来改进结构和工艺。

方案介绍

该基站天线淋雨试验解决方案主要有三部分组成：喷淋系统、储水系统、控制系统。内部加装两种夹具，可分别模拟对前置照明灯、后置警示尾灯两种类型的车灯测试。

基站天线淋雨试验解决方案-参考图

【警示灯淋雨试验】可通过斜面型喷淋管进行淋水测试，喷淋孔大小为直径1.0mm，每个喷淋工位有9个喷淋孔。单排可放置13个试样。通过斜角度淋雨，可模拟警示灯在行进中被后轮滚动带来的溅水状态。喷淋距离为100mm，保持了一定的淋水冲击力度。

【照明灯淋雨试验】单排可放置13个试样，每个工位布局一个喷淋头，喷淋直接正面对着试样，喷淋距离为100mm。

【顶部雾化淋雨】箱体顶部布局两根雾化淋雨器具，每根淋雨器具分别布局三个雾化型淋水喷嘴。喷雾角度60度，每个喷头在喷头下400mm处形成直径462mm的圆，可覆盖到真个淋雨内箱，模拟车灯在大雾天气下的防护性能。顶部雾化淋雨流量大小可通过手动调节。

【控制系统】通过7寸触控屏+PLC可编程控制器组成控制系统，采用岳信自主设计的操作界面，功能齐全，简单易学；面板上安装有急停按键，可便于应对紧急情况处理。流量采用面板流量计，可由用户自行调节。

【储水系统】内置储水箱，可保持整个淋雨箱处于可循环淋雨状态，提高了检测效率。

方案价值

该基站天线淋雨试验解决方案由岳信公司根据客户要求研发，根据自行车灯在户外常遇到的淋雨天气或大雾天气而设计。较真实的模拟了车灯在雨天情况下的可能遭受的淋水情况。该方案不同于常见的IP防护等级测试，没有指定的测试标准。但其测试方法对于车灯企业有一定的借鉴之处。
