<p>An intelligent power supply detection and control apparatus comprises: a master controller circuit (101), an AC power supply management circuit (102), and an AC illuminator drive circuit (108). An input end of the master controller circuit is connected to an illumination state detection circuit (103), an AC-N circuit on/off and power off detection circuit (104), an AC-L circuit on/off and power off detection circuit (105), and a master-control power supply and battery charging management circuit (106). An output end of the master controller circuit is connected to a DC illuminator drive circuit (107). The master controller circuit can control turn-on, prolonging of the turn-on state, or turn-off by turning on/off the illuminator and according to the power-on or power-off state of the line. When the power is off, the illuminator is used as an emergency lamp, and it is not required to additionally arrange the lines and mount the emergency lamp.</p> |
