Abstract
Disclosed is a system and method for power line control of devices. The system operates in two modes. In mode one, the system operates on an open loop architecture with a controller generating a sinusoidal wave using a crystal oscillator. Control information is added to the sinusoidal wave by alternating the output of two phase shifted waves which have the same frequency and amplitude to form a control signal. The resulting control signal is sent on a power line. The control signal is received using a crystal filter, decoded and converted to executable instructions for the devices and data parameters for sensors. In mode two, the system operates on a hybrid open loop/closed loop architecture where devices are jointly controlled by the controller and the sensors.
