Technical Field
The invention relates to the field of intelligent household power supply control, in particular to a low-power-consumption intelligent household power supply management method and a control method.
Background
The intelligent home is characterized in that a home is used as a platform, facilities related to home life are integrated by utilizing a comprehensive wiring technology, a network communication technology, an intelligent home system design scheme, a safety precaution technology, an automatic control technology and an audio and video technology, an efficient management system for home facilities and family schedule affairs is constructed, and a user can effectively control energy and electricity to use no matter whether the user is at home or outside through the intelligent home system connected through remote control, so that the home safety, convenience, comfortableness and artistry are improved. Scenes of smart homes have been developed and applied to smart lighting, smart door locks, smart doors and windows, security alarms, environmental monitoring, audio-visual interactive entertainment and the like.
The smart home system inevitably has a large number of electrical devices, such as televisions, sound equipment, projectors, air conditioners, lighting, door locks, security monitoring, washing machines, smart doors and windows and other devices, and meanwhile, devices which run continuously for a long time, such as refrigerators, routers and the like. The intelligent home requires all the electric equipment participating in interactive linkage to wait for instructions at any time, so that the equipment which does not need to work for a long time is necessarily in a standby working state. When many devices are in standby state for a long time and accumulated for a long time, the standby energy consumption is considerable. An investigation of international cooperative organizations shows that energy consumed by each country due to standby accounts for 3-13% of total energy consumption, and standby energy consumption of China is higher than the international average level.
Now, with the technological progress, the standby power of the household appliances is also continuously reduced, and China also actively responds to the international 1W initiative, and the standby power of the corresponding equipment is recommended to be reduced to below 1W in a plurality of national standards. But the household appliances in China have long replacement period and a large amount of old equipment is still in service. As can be seen from table 1, the standby power of most appliances exceeds 1W. Even if all devices can realize 1W standby power, long-time standby still causes no small energy consumption.

The super capacitor module 12 is configured to provide the electric quantity required by standby for all the standby devices in the smart home device in real time.
The super capacitor control module 13 is connected with the smart home device 2 and is used for controlling the super capacitor module to provide standby electric quantity for the devices in the smart home device 2 respectively.
The intelligent household equipment 2 comprises equipment such as an intelligent television, an intelligent sound, an intelligent projector, an intelligent air conditioner, intelligent lighting, an intelligent door lock, intelligent security monitoring, an intelligent washing machine, an intelligent door and window, an intelligent door lock and the like;

The alternating current bus control module 32 is connected with the smart home device 2 and is used for controlling the alternating current bus power supply module to provide working electric quantity for the devices in the smart home device 2 respectively.
Referring to fig. 2, since the smart home devices generally control the states of the smart home devices, such as on/off, start, standby, and the like, by an intelligent method, if the light sensor senses darkness, the light will be automatically turned on; after the sensor detects that no person is in the room, the computer, the television, the air conditioner and other equipment can be automatically turned off; the starting time of the equipment can be defined by user, and the equipment can be started at fixed time, closed at fixed time and the like.
Therefore, when the intelligent method sends a starting instruction to a certain intelligent household device, the super-capacitor energy storage module 1 immediately cuts off the power supply after the related devices in the intelligent household system start, and the alternating current bus module 3 provides the related devices for power consumption at the moment. When the intelligent method sends a standby instruction to a certain intelligent household device, the certain device in the intelligent household device 2 stops working, the standby/start control module 5 starts response immediately, and requests the super-capacitor energy storage module 1 to provide standby energy for the corresponding device;

The method provided by the invention can reduce the energy consumption of the electrical appliance which does not work continuously, and the system is not connected with the alternating current of the commercial power, thereby generating no electric charge. For families or small and medium-sized enterprises with more electrical equipment, the consumption of the alternating current power of the commercial power for standby of the equipment can be obviously reduced or even avoided.
