    • A powerline network system having data relay function includes a plurality of power monitoring zones mutually connected with a powerline network and at least one repeater. Each of the power monitoring zones has at least one power monitoring device. The repeater is connected with each power monitoring device in two adjacent power monitoring zones through powerlines and has a first and a second relay units. The first and second relay units employ two different sets of transmitting and receiving bands to fetch data contained in powerline signals transmitted by each power monitor in adjacent power monitoring zones. The data are received by a relay unit are modulated with different transmitting band and then transmitted to powerlines of another power monitoring zone. The repeaters are not required to be serially connected to the powerlines, and incorrect data read can be also eliminated.
    • 具有数据中继功能的电力线网络系统包括与电力线网络和至少一个中继器相互连接的多个电力监控区域。 每个电力监控区具有至少一个电力监控装置。 中继器通过电力线与两个相邻电力监控区域中的每个电力监控设备连接,并具有第一和第二继电器单元。 第一和第二中继单元使用两组不同的发射和接收频带来获取由相邻电力监测区域中的每个功率监视器发送的电力线信号中包含的数据。 由中继单元接收的数据以不同的发送频带进行调制,然后发送到另一个电力监控区域的电力线。 中继器不需要串联连接到电力线上,也可以消除不正确的数据读取。

    • A digital automatic monitoring and power breaking safety socket has a shell in which an electrical connection base is mounted for connecting to a power line and an external line plug inside. A power switch is connected in series between the electrical connection base and the power line. A digital power monitoring circuit is coupled to the power line detect the power status to control the power switch based on the power status. Further, a power line data communication circuit is mounted in the shell and connects to the digital power monitoring circuit to obtain and process the power status. The processed power status is loaded into the power line that connects to the electrical connection base. Therefore, in addition to automatic power breaking and supplying, a remote power management host is able to obtain the power status and remotely control the socket.
    • 数字自动监测和断电安全插座具有壳体,其中安装有电连接基座用于连接到电力线和外部线路插头。 电源开关串联在电气连接基座和电源线之间。 数字电源监控电路耦合到电源线,根据电源状态检测电源状态,控制电源开关。 此外,电源线数据通信电路安装在外壳中并连接到数字电源监控电路以获得并处理电源状态。 处理后的电源状态被加载到连接到电气连接基座的电力线上。 因此,除了自动断电和供电之外,远程电源管理主机能够获得电源状态并远程控制插座。
