1. A method used in a UPS (Uninterruptible Power Supply) system for automatically strengthening energy-saving and electrical safety, said UPS system being electrically connected to an input power supply, said UPS system comprising a microcontroller, an AC to DC converter, a DC to AC converter, a transfer switch and stored energy systems, said AC to DC converter, said DC to AC converter and said transfer switch being respectively electrically connected to said microcontroller, said input power supply being electrically connected to said AC to DC converter and said transfer switch, said AC to DC converter being electrically connected to said DC to AC converter, said DC to AC converter being electrically connected to said transfer switch, said transfer switch being adapted for outputting power supply to a load, said stored energy systems electrically connected to the circuit between said AC to DC converter and said DC to AC converter, said transfer switch being controllable by said microcontroller to switch said UPS system between a Normal Mode where said input power supply is transmitted through said AC to DC converter and said DC to AC converter to said transfer switch for outputting power to said load and an Eco Mode where said input power supply is directly transmitted to said transfer switch for outputting power to said load, the method comprising the steps of:
(A01) start;
(A02) determining whether or not to automatically execute energy parameter setting, and then proceeding to step (A03) if negative, or step (A07) if positive;
(A03) manually setting at least one of the parameters of power environment, time and empiric by: entering step (A04) to set the power environment parameter, step (A05) to set the time parameter and step (A06) to set the empirical parameter;
(A04) performing power environment parameter setting, and then proceeding to step (A12);
(A05) performing time parameter setting, and then proceeding to step (A12);
(A06) performing empirical parameter setting, and then proceeding to step (A12);
(A07) collecting power environment data;
(A08) collecting load status data;
(A09) collecting power usage data;
(A10) setting the priority of the determination conditions to be electrical safety at the highest priority, energy-saving at the highest priority, or, both electrical safety and energy-saving into consideration;
(A11) performing data statistic and storage;
(412) performing data analysis and judgment;
(A13) judging whether or not to perform energy-saving, and then proceeding to step (A14) if positive, or step (A15) is negative;
(A14) automatically performing the Eco Mode, and then proceeding to step (A16);
(A15) automatically performing the Normal Mode, and then proceeding to step (A16);
(A16) ending the procedure, and then returning to step (A01).
