The electricity of the energy-storage battery is detected, if the electricity of the energy-storage battery is less than preset value, controls pole changer photovoltaic generation
The photovoltaic DC of plate transmission is electrically directed to DC/DC converters, charges for energy-storage battery, if the electricity of the energy-storage battery is higher than default
Value then controls the photovoltaic DC that pole changer photovoltaic power generation plate is transmitted to be electrically directed to DC/AC inverters, powers to AC network, be
AC network electric energy supplement.
Further, the electric appliance managing device is also connected with Cloud Server, as shown in figure 3, electric appliance managing device will
Its electricity consumption characteristic information of each electrical appliance being collected under the first working condition and the second working condition is sent to Cloud Server,
The Cloud Server includes data obtaining module, history module, Characteristic Contrast module and analysis module, and described information obtains
The status signal that module is sent first according to electric appliance managing device, to determine that current power device is in the first working condition or the
Two working conditions, and according to the first working condition and the difference of the second working condition, for receive the first of each electrical appliance
Working condition and the second working condition distribute different memory spaces in history module, divide in the history module
Not Cun Chu different times (different time sections of such as one day) each electrical appliance the first electricity consumption characteristic information or second use electrical feature
Information is stored with the corresponding electrical appliance state of different electricity consumption characteristic informations in the Characteristic Contrast module, such as the electricity consumption of electrical appliance 1
Characteristic information 1 corresponds to electrical appliance 1 and is operated in the extremely high state of power, and the electricity consumption characteristic information 2 of electric appliance 1 corresponds to 1 work of electrical appliance
Make in extremely low state of power, etc., the Characteristic Contrast module obtains electrical appliance by the comparison to electricity consumption characteristic information
The conclusion of working condition, and by the electricity consumption behavior of analysis module analysis electrical appliance, for example, user only uses electrical appliance 1, the use
Electric appliance is 8:00 moment entered the first working condition, and 8:00~12:It works in the first operative state during 00, during which,
Electrical appliance 1 is 8:00~8:It is high power consuming features during 10,8:10~12:It is normal power consuming features during 00；Afterwards, exist
12:00~17:It is the second working condition between 00, electrical appliance 1 is 12:00~13：00 is normal power consuming features, 13：00~
15:00 is power consumption protection feature (feature occurred due to the decline of energy-storage battery voltage), 15:00~17:00 for power not
The feature of foot.17:After 00, electrical appliance 1 is again into the first working condition.By information derived above, analysis module is extremely
Electrical appliance 1 can be analyzed less as the electrical appliance with power consumption protection feature, and the decline of storage batteries voltage has electrical appliance 1
Larger impact, in the case where only using electrical appliance 1, energy-storage battery can use when a length of 5 hours etc. and electrical appliance electricity
Relevant information can be used.By analysis of the long-term (such as one month) to each electrical appliance electrical feature, it is concluded that working as
The laws of use of electrical appliance under preceding scene, for user, further prediction and analysis electrical appliance service condition carry out carrying for data
For.
Further, the Cloud Server also has wireless sending module, for wirelessly being connected with user's handheld terminal
It connects, the service condition of each electrical appliance can be pushed to user's handheld terminal periodically or in real time, relevant information is obtained convenient for user.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
The spirit of utility model and any modification, equivalent substitution, improvement and etc. within principle, done, should be included in the utility model
Within the scope of protection.
