The invention discloses an electric energy meter cost control system, an electric energy meter and a cost control method of the electric energy meter. The system comprises a cost control signal receiving device and a cost control signal processing device, the cost control signal receiving device comprises a cost control signal receiving circuit, a half-wave rectifying circuit and a light generating unit; the cost control signal processing device comprises a light receiving unit and a processing unit; the light generating unit and the light receiving unit form an optical coupler structure; wherein the charge control signal receiving circuit is used for receiving an alternating current signal for controlling the metering rate of the electric energy meter; the half-wave rectifying circuit is used for rectifying the alternating current signal into a first direct current signal; the light generating unit is used for emitting light according to the first direct-current electric signal; the light receiving unit is used for generating a second direct current electric signal according to the received light signal; the processing unit is used for controlling the metering rate of the electric energy meter according to the second DC signal. The problem that an existing cost control scheme is poor in flexibility can be solved.
Description
technical field [0001] The invention relates to the field of electric energy meter charge control, in particular to an electric energy meter, a charge control method and system. Background technique [0002] At present, energy meters that support peak-valley electricity billing are generally integrated with RTC chips, and the current rate plan that should be implemented is determined by the internal clock and the rate table. [0003] On the one hand, since the RTC cannot run normally when it is not connected to the mains, even adding a supercapacitor or battery to supply power to the RTC chip can solve the phenomenon that the RTC cannot run normally when it is not connected to the mains. The power is limited, and there is no guarantee that the RTC can still run normally when it is not connected to the mains for a long time. On the other hand, due to the high cost of supercapacitors and batteries, using batteries and supercapacitors as backup power for the RTC chip will undo...
