Electrical equipment power control method and device

Abstract

The invention is adapted to the field of electrical equipment control and provides an electrical equipment power control method. The electrical device comprises communication interfaces, instant power detectors and equipment actuators. The equipment actuators and the instant power detectors are connected with a control center through the communication interfaces. The method comprises that the instant power detectors detect the electrical equipment instant operation power; the control center receives the instant operation power sent by the electrical equipment to determine the power sum of the current operation electrical equipment; the communication interfaces send adjusting instructions to the electrical equipment actuators if the power sum is larger than the preset power limit value to adjust the electrical equipment operation power. By means of the method and the device, effects on use of equipment caused by the power failure can be prevented, the system cost and the control cost are saved, and electrical equipment can be managed centrally uniformly.

Description

technical field [0001] The invention belongs to the field of electric appliance control, and in particular relates to a power control method and device for electric equipment. Background technique [0002] The traditional methods of heating food with fuel, such as coal and natural gas, will pollute the environment due to the generation of harmful gases or dust during combustion. As the world pays more attention to clean energy, electrical equipment heated by electromagnetic or microwave is more and more popular because of its high reuse rate, clean and pollution-free. In addition, with the continuous development of automation control technology, more and more electrical equipment has entered people's lives, such as washing machines, refrigerators, electric water heaters, etc. [0003] With the continuous increase of electrical equipment, multiple electrical equipment may be used at the same time, thus placing an upper limit on the power of the entire system. Due to the powe...

Problems solved by technology

[0005] The purpose of the present invention is to provide a power control method for electrical equipment to solve the problem of cutting off the power supply in the prior art when the power is overloaded, so that all equipment stops working. For equipment that moves according to a predetermined program, such as a washing machine or an electric cooker. After reconnecting the power supply, it is necessary to restart the work, which affects the use effect of the equipment
