Power line carrier communication based generator control apparatus and control method

The invention provides a power line carrier communication based generator control apparatus. The generator control apparatus comprises a transmitting end which is detachably mounted on an indoor socket and a receiving end which is arranged on a control panel of an outdoor generator, wherein the receiving end and the transmitting end are connected through a power line; and the transmitting end sends a generator starting signal or a generator stopping signal to the receiving end according to the voltage signal of the power line and an external triggering operation. By adoption of the generator control apparatus, a power generation voltage detection feedback unit is added on the transmitting end and an ignition pulse detection feedback unit is added on the receiving end; the internal closed loop control of the power generation control apparatus is realized; the reliability of the control is improved; a misoperation is prevented; and when a misoperation is done by a user, a wrong signal is not sent to the generator, so that the safety in use is ensured. According to the generator control apparatus provided by the invention, one-to-one control for the generators can be realized; the misoperation in the remote control can be avoided; the use convenience for the users can be improved.
