Description

Public Power Network Controller

【Technical field】

The utility model relates to a controller which utilizes a public power network to transmit signals, which can be applied in the fields of Internet, communication, monitoring, transportation and the like.

【Background technique】

PLC (Power Line Communication) is a technology that uses power lines to transmit signals. Its development is based on the fact that every family has multiple power outlets. If a technology that uses power cords as a transmission medium can be developed, it will be possible to integrate the control of computers and various home appliances, making life more convenient.

This new concept has attracted many manufacturers to invest in development, and established a "Basic Power Transmission Line Home Network Alliance HPA (HomePlug Powerline Alliance)" to formulate some specifications and do some compatibility tests for various manufacturers.

With the gradual maturity of PLC technology, HPA released the first specification "HomePlug 1.0" in 2001. HomePlug, the latest network specification, provides a stable, high-speed, long-distance and non-electromagnetic wave network environment, so that it is combined with the Internet to develop a PLC Modem (power line network modem).
