Description

technical field

[0001] The invention relates to electronic equipment, in particular to an electric meter. Background technique

[0002] With the vigorous transformation of the power infrastructure construction by the national power department to meet the needs of the majority of users for power, the difference between peak power consumption and low-peak power consumption has become very obvious. Many local power departments feel the power consumption during peak hours Insufficient resources, and power resources are not fully utilized during off-peak hours, resulting in a great waste of resources. Therefore, the electric power sector is promoting electricity meters that use built-in clocks and store electricity price information tables for peak and valley periods (some are divided into three or four periods). The electricity consumption degree of the time period.
