iec104

iec104主站golang实现

quickstart

修改.env中的从站地址

执行docker-compose up

develop

  1. 修改.env中的从站地址
  2. 安装依赖 make deps
  3. 修改example/client/worker/worker.go来处理通过104协议收到的数据
  4. 运行example中的104主站程序 make client

104规约解析

遥信起始地址1H<=>1

遥测起始地址4001H<=>16385

遥脉起始地址6001H<=>24577

实现功能

  1. 每15分钟进行一次总召唤，第一次触发为激活后。

  2. 每15分钟进行一次电度总召唤，第一次触发为总召唤结束后。

  3. 主备切换，断线重连

  4. 信号量解析

    3.1. M_SP_NA_1=1 单点遥信

    3.2. M_DP_NA_1=3 双点遥信

    3.3. M_ME_NA_1=9 带品质描述的遥测

    3.4 M_ME_NC_1=13 浮点数遥测

    3.4 M_IT_NA_1=15 电度总量遥脉

    3.5. M_SP_TB_1=30 带7个字节短时标的单点遥信
