The technical problem to be solved by the present application is to provide an indoor power line transmission control system, which realizes the flexibility of having no wiring, simple extension, smart dimming, and thereby saving energy.

In order to achieve the above objective, the present application adopts the following technical solutions.

An indoor power line transmission control system is provided. The control system includes: a transforming dimming controller, which is configured to load, onto an electrical signal, a received dimming signal sent by a mobile terminal or input by a user in a touch-control manner, and to send the electrical signal loaded with the dimming signal to a dimming driver; and the dimming driver, which is electrically connected with the transforming dimming controller and a dimming luminaire, and configured to read the electrical signal loaded with the dimming signal, and to adjust a gray scale of the dimming luminaire according to the read electrical signal.

The transforming dimming controller includes:

a first power supply processor, which is connected to mains, and configured to convert the mains into an alternating current adapted to the dimming luminaire, and to transmit the alternating current to a first power line transmission modem;

a first logic control digital module, which is configured to receive the dimming signal sent by the mobile terminal or input by the user in a touch-control manner, and to transmit the received dimming signal to the first power line transmission modem; and
