3. 4G模块部分

3.1 自测用4G模块, 现场稳定运行2年多

  • 内置eSIM卡, 每月100M流量, 含8年服务
  • 多种参数设置方式：网络、短信、串口 AT 指令、电脑端设置软件配置、微信小程序配置；
  • 支持 5~16V 宽电压供电，适配更多应用场景；
  • 体积超小，自带导轨和伸缩式挂耳，安装方便；
  • 网络透传模式拥有 4 路独立 socket，支持各路 socket 备份，支持 KEEP-ALIVE 机制，增强连接稳定性；
  • 每路连接支持 20 包数据缓存，每包数据最大 4K，支持注册包，心跳包数据；
  • 多种指示灯，设备工作状态判断直观准确。
  • 设置网络参数: TCP短连接/超时60秒/无心跳(只有数据时才上报), 平台端为TCP Server, 端口1508
  • 设置串口参数:

3.2 支持自选4G模块

  • 若4G模块需要独立设置, 适配修改分机代码
