C#网络类智能开关控制板实例

网络类智能开关控制板采用 TCP/IP 协议与控制主机（PC 机）进行通讯，运
行稳定可靠，传输距离远，尤其适合不方便布线的场所。每块开关板分配一个唯
一的 IP 地址，通过 IP 地址进行控制数据的传输区分；每个开关触点容量为
220V/10A，一般情况下推荐使用到 6A 左右，太大的电流请使用我公司的 30A 控
制卡。
网络类普通型号（有线、无线和混合网络）可以直接连路由器，手机和电脑
连接路由器后均可以控制，但是异地远程需要路由器所在网络有外网 IP，通过
花生壳+端口映射即可实现异地远程。云转发型号直接支持异地远程，插上网线
手机和电脑软件中输入设备序列号即可异地远程进行开关控制
