Home electricity distribution control system and method

Abstract

The invention discloses a home electricity distribution control method. The home electricity distribution control method includes: 1), transmitting total power supply voltage and open-circuit voltage, firing current, operating states, operating and non-operating time of electrical appliances to a memory unit and a calculating unit of a single-chip microcomputer control unit; 2), the calculating unit calculating voltage drop and electric power of the electrical appliances as well as total voltage drop and total electric power of a system, and calculating operating hours of the electrical appliances and transmitting calculating results to the memory unit for storage; 3), at some time, a comparison unit comparing the calculating results of the calculating unit with corresponding rating data in the memory unit; 4), sending powering off or powering on instructions to a corresponding power supply output control unit according to results of the comparison unit, and repeating the step 1), 2), 3) and 4) so as to perform real-time electricity distribution on the electrical appliances. The invention further provides the control system assorted with the home electricity distribution control method. Operating states of the electrical appliances in the system are timely adjusted according to needs of the electrical appliances, and overload operation of the system is avoided.

Description

technical field [0001] The invention relates to the field of electric energy control systems, in particular to a household electric energy distribution control system and method. Background technique [0002] The modernization of daily life has brought household appliances such as refrigerators, microwave ovens, ovens, electric baking pans, water heaters, electric pressure cookers, and electric heaters into thousands of households. However, when people enjoy these appliances, there will be sudden power failures and trips. And other problems occur, which have a negative impact on life. The reason is partly because a variety of electrical appliances supply power at the same time, resulting in overloading of the electricity load, and the circuit enters automatic protection; the other part is due to a failure of some electrical appliance, and the excessive current causes the circuit to be interrupted. The overload operation of the power supply line has caused serious safety haz...

[0002] The modernization of daily life has brought household appliances such as refrigerators, microwave ovens, ovens, electric baking pans, water heaters, electric pressure cookers, and electric heaters into thousands of households. However, when people enjoy these appliances, there will be sudden power failures and trips. and other problems occur, which have a negative impact on life

The reason is partly due to the simultaneous power supply of multiple electrical appliances, resulting in overloading of the power load, and the circuit enters automatic protection; the other part is due to a failure of some electrical appliance, the current is too large and the circuit is interrupted

The overload operation of power supply lines has caused serious safety hazards to household electricity consumption. Long-term overload operation will cause aging of the lines and leakage of electricity, which is very easy to cause accidents
