The invention discloses an energy conservation monitoring system of electric equipment. A local processing system comprises a power consumption measurement module, a real-time state acquisition module, an information storage and processing module, a safety verification module, a control module, a receiving module and a local communication module, wherein the real-time state acquisition module is connected with the information storage module; the receiving module receives tiered electricity pricing information from a remote power supply system and transfers the tiered electricity pricing information to the control module; an energy storage system performs power storage during the time period of low electricity price, the energy storage system finds out the time value of the high electricity price time period by looking up a power usage state table of the previous day, and the energy storage system supplies power to the electric equipment at the time value of the day; and the energy conservation monitoring system calculates the rated value of the total daily electricity consumption of the electric equipment in a preset mode, when the total electricity consumption of the electric equipment exceeds the rated value, the energy conservation monitoring system sends alarm information to users, and the users can shut down the electric equipment in an additional function state to achieve the purpose of saving the power consumption.
