COMMUNICATION SYSTEM FOR ELECTRIC LOAD CONTROL Russian patent published in 2016 - IPC H05B37/02 H04B3/54 

FIELD: physics.

SUBSTANCE: use: in electric engineering. The system comprises: control device (1), that at one side is connected to a phase line (L) of a power voltage source (4), and which output creates a load line (L') to connect at least one load or a load module (2.1, 2.2, 2.n); that at another side is connected with a neutral wire (N) of the power voltage source (4). The control device (1) only during time windows (EF) of energy transmission periodically occurring for the power voltage (U) conducts the power current from the source (4) to at least one module (2.1, 2.2, 2.n), and during communication time windows (KF), not overlapped with the time windows (EF) of energy transmission the bidirectional communication is ensured due to the registration and/or modulation of the communication current via the load line (L') between the control device (1) and at least one load module (2.1, 2.2, 2.n). Wherein at least one module (3.1, 3.2, 3.m) of load extension is provided; at one side it is connected with the phase line (L), and at another side with the load line (L'), and via the control line (S) it is connected with the control device (1). The module (3.1, 3.2, 3.m) of load extension is controlled such that during the time window (EF) of energy transmission, but not during the communication time window (KF) the power supply current passes from the power voltage source (4) to at least one load module (2.1, 2.2, 2.n).

EFFECT: possibility of large loads control.
