module and at least one luminaire, the luminaire is powered by the emergency power module in a state when the live line and the null line are not regularly powered, and the luminaire is capable of extracting the digital signals loaded on the live line and/or the null line and adjusting its own working mode according to control commands corresponding to the digital signals. ## Claims ### Claim 1 An intelligent emergency power supply system, comprising: a power line, wherein said power line comprises a live line and a null line, a signal communication module, wherein said signal communication module is electrically connected to said live line and said null line to load digital signals on said live line and/or said null line, and to receive digital signals on said live line and/or said null line, an emergency power module, and a luminaire, wherein said luminaire is electrically connected to said live line and said null line via said emergency power module and is powered by said emergency power module in a state when said live line and said null line are not regularly powered, wherein said luminaire comprises a driver circuit, a signal processing circuit, and at least one illuminating load, wherein said driver circuit is electrically connected to said emergency power module to access electrical energy from said emergency power module so as to drive said illuminating load electrically connected to an output of said driver circuit, wherein said signal processing circuit is electrically connected to said emergency power module and said drive circuit so as to extract digital signals loaded on said live line and/or said null line and to control the operation of said drive circuit based on the corresponding signals. ### Claim 2 (depends on 1) The intelligent emergency power supply system, as recited in claim 1, wherein said intelligent emergency power supply system comprises an isolation module, wherein said isolation module is provided at a front end of said live line and said null line to block interference signals in a municipal power supply line from entering said intelligent emergency power supply system and/or to block digital signals from escaping out of said intelligent emergency power supply system. ### Claim 3 (depends on 2) The intelligent emergency power supply system, as recited in claim 2, wherein said signal processing circuit comprises a pre-processing unit and a control unit, wherein said pre-processing unit is arranged to access and step down the high voltage signal from said live line and/or said null line, wherein said control unit is electrically connected to said pre-processing unit and is arranged to decode the signal processed by said pre-processing unit to obtain a corresponding control signal, so as to control said drive circuit according to the corresponding control signal. ### Claim 4 (depends on 2) The intelligent emergency power supply system, as recited in claim 2, wherein said emergency power module and said luminaire are separated and are provided in the form of a centralized emergency power supply. ### Claim 5 (depends on 4) The intelligent emergency power supply system, as recited in claim 4, wherein said signal communication module and said emergency power module are integrated. ### Claim 6 (depends on 2) The intelligent emergency power supply system, as recited in claim 2, wherein said emergency power module is built into said luminaire and is provided in the form of an individual emergency power supply. ### Claim 7 (depends on 3) The intelligent emergency power supply system, as recited in claim 3, wherein said emergency power module comprises an energy storage unit and an inverter circuit, wherein said energy storage unit is electrically connected to said live line and said null line and is arranged to be able to be charged and to store energy in response to a state of regular power supply of said live line and said null line, and be able to output electrical energy in a state of irregular power supply of said live line and said null line, wherein said inverter circuit is electrically connected to said energy storage unit, based on the corresponding parameter settings of said inverter circuit, to enable said luminaire to output the corresponding power according to the corresponding emergency settings in the state of irregular power supply of said live line and said null line. ### Claim 8 (depends on 3) The intelligent emergency power supply system, as recited in claim 3, wherein said control unit is powered by and connected to said drive circuit so as to operate and be powered by said drive circuit. ### Claim 9 (depends on 8) The intelligent emergency power supply system, as recited in claim 8, wherein said emergency power module is built into said luminaire and is provided in the form of an individual emergency power supply. ### Claim 10 (depends on 3) The intelligent emergency power supply system, as recited in claim 3, wherein said control unit is provided in the form of an integrated circuit. ### Claim 11 (depends on 3) The intelligent emergency power supply system, as recited in claim 3, wherein said emergency power module and said luminaire are separated and are provided in the form of a centralized emergency power supply. ### Claim 12 (depends on 11) The intelligent emergency power supply system, as recited in claim 11, wherein said signal communication module and said emergency power module are integrated. ### Claim 13 (depends on 3) The intelligent emergency power supply system, as recited in claim 3, wherein said emergency power module is built into said luminaire and is provided in the form of an individual emergency power supply. ### Claim 14 (depends on 7) The intelligent emergency power supply system, as recited in
