The invention relates to a centralized intelligent electric meter. The electric meter comprises a plurality of electric energy sampling modules, wherein each electric energy sampling module is connected with a measuring module; the measuring module is connected with a signal selection module; the signal selection module is connected with a control processing unit; the control processing unit is connected with a display module; each electric energy sampling module acquires the electric quantity of each user and transmits the acquired signal to the measuring module; the measuring module converts the signal acquired by each electric energy sampling module into a frequency signal; the frequency signal passes through the signal selection module and is transmitted to the control processing unit; and the control processing unit processes the signal and transmits the processed signal to the display module for display. The electricity utilization data of a plurality of users is centralized on the same display screen for polling display, so that the requirement of the electric meter on an installation position is reduced, the meter reading efficiency of meter reading personnel is improved, and management and maintenance cost is reduced.
