Claim 5:
6. The emergency start control method according to claim 1, wherein the step of sequentially obtaining and storing dimming parameter values of the load lighting equipment at required power based on an input-terminal power signal of a boost inverter of the emergency lighting circuit, and establishing a dimming database comprises:
gradually increasing a dimming signal outputted to the load lighting equipment in an active emergency lighting state;
sequentially acquiring the input-terminal power signal of the boost inverter of the emergency lighting circuit under each dimming signal;
storing, when the input-terminal power signal reaches preset emergency power, a dimming signal corresponding to the input-terminal power signal as a required dimming parameter value corresponding to the load lighting equipment in an emergency operation state;
establishing the dimming database according to required dimming parameter values corresponding to the load lighting equipment in the emergency operation state.
