Control system and power line network containing the same
First Claim
1. A control system for controlling a power line network having a power line, at least one electric appliance and at least one controller, wherein the control system comprises a central control unit, wherein the central control unit is configured to manage the power line network such that:
- controls over the at least one electric appliance by the at least one controller is programmable; and
signals for the controls are transmitted through the power line;
the control system further comprising an on-site control unit, wherein the on-site control unit comprises at least one modulator and at least one demodulator, each coupled with the central control unit, wherein;
each of the at least one modulator is coupled with the at least one controller and is configured, upon receiving a first control signal from the at least one controller, to generate and transmit a second control signal to the central control unit;
the central control unit is configured, upon receiving the second control signal, to generate a third control signal in correspondence with the second control signal, and to transmit the third control signal to the at least one demodulator;
each of the at least one demodulator is coupled to the at least one electric appliance, and is configured, upon receiving the third control signal, to generate a fourth control signal, and to transmit the fourth control signal to, and to thereby control, the at least one electric appliance;
the central control unit comprises a receiving module, an inquiry module, a storage module and a transmitting module;
the storage module is coupled with the receiving module, and is configured to store correspondence information between the second control signal and the third control signal;
the receiving module is coupled with the at least one modulator through the power line, and is configured to receive the second control signal from each of the at least one modulator, and to transmit the second control signal to the inquiry module;
the inquiry module is coupled with the storage module and the transmitting module, and is configured to query the correspondence information based on the second control signal, and to transmit the corresponding third control signal to the transmitting module; and
the transmitting module is coupled with the at least one demodulator through the power line and is configured to transmit the corresponding third control signal to the at least one demodulator.

Abstract
A control system for controlling a power line network having a power line, at least one electric appliance and at least one controller includes a central control unit, configured to realize programmable controls over the appliance by the controller with signals transmitted through the power line. An on-site control unit includes at least one modulator and at least one demodulator coupled with the central control unit. Each modulator is configured, upon receiving a first control signal from the controller, to generate and transmit a second control signal to the central control unit that is configured, upon receiving the second control signal, to generate and transmit a third control signal to the demodulator. Each demodulator is configured, upon receiving the third control signal, to generate and transmit a fourth control signal to the appliance.
