Abstract

Provided is a switching method for charge control modes of a single-phase intelligent electric energy meter. A local charge control mode and a remote charge control mode are triggered off to switch according to a remote encryption instruction or a switching time signal preset in the interior of the electric energy meter. A master control module is used for automatically controlling an I / O port to refresh and automatically turn on or off function module only in the charge control mode and then automatically switching display content of a display module. In addition, the master control module is used for automatically settling historical data, recording switching events and saving historical data and switching events by means of a storage module. Therefore, the local charge control mode and the remote charge control mode can be reliably and flexibly switched in order to satisfy needs of electric energy measurement and settlement.

Description

technical field

[0001] The invention relates to the technical field of electricity metering, in particular to a method for switching charge control modes of a single-phase smart electric energy meter. Background technique

[0002] At present, the existing single-phase smart energy meters only have a single fee control mode, that is, remote fee control mode or local fee control mode.

[0003] Remote fee control mode: based on the metering mode of electricity billing, it does not calculate and deduct electricity bills, but only has the functions of metering, freezing and settlement of electricity. The method regularly reads the data of the settlement electricity in the energy meter to settle the electricity bill, and can realize operations such as opening and closing the energy meter through the remote command of the upper computer of the electricity sales system.

[0004] Local fee control mode: Based on the metering mode of electricity bill settlement, it can automatically ...
