Rest on the most always and simply use kilowatt-hour meter and carry out an elementary step for moon power consumption statistics.
Along with improvement and the raising of people's living standard of material conditions, household electrical appliance are more prevalent, extensively transport
For family life.Electrical Safety has become the importance index of modern furniture electricity consumption, and household electricity has also become joint
Energy, the key areas of environmental protection.To this end, household electricity situation is effectively monitored and controlled, to safeguard house
Front yard Electrical Safety and environmental protection become more to be necessary.
But, household electricity energy-saving safe is a long-term process, equally exists when user goes out,
Therefore the electricity consumption situation that is desirable to make user grasp in own home at any time also can remotely control.If
Existing personal telecommunication terminal can be utilized, it is achieved the mobile phone long-range monitoring to household electricity, both can save throwing
Money, is easy to again promote.

Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of household electric information interaction inquiry system, including host terminal, from machine
Terminal and intelligent electric meter, host terminal connect one or more from machine terminal, one connects from machine terminal
One or more intelligent electric meters, and are equipped with RS485 interface on intelligent electric meter from machine terminal, pass through RS485
Interface makes to carry out data transmission with intelligent electric meter from machine terminal, host terminal and from machine terminal be equipped with electric power carry
Ripple PORT COM, makes host terminal communicate with one another with from machine terminal by power carrier communication port, main
Machine terminal is provided with LCD touch screen, for query display power information, arrearage information, buys payment information
Be used for providing user's input information.
From machine terminal be provided with MCU, MCU be micro-control unit also known as one chip microcomputer, be used for performing solid
The embedded program changed.
Host terminal is connected with plug by power line, and power line is synthesized by communication line and supply line.
Host terminal is provided with audible-visual annunciator, is used for pointing out arrearage alarm.
Host terminal is provided with 3G/ broadband interface, by 3G network or home broadband by equipment running status and
Electric fees charging state is reported and submitted to power equipment operator and electricity service provider, is used for allowing power equipment run
Business and electricity service provider understand User Status.
Host terminal is provided with LED, the most properly functioning for display system.
Native system main frame provide man machine interface, by LCD touch screen display electric energy use, arrearage point out and
Buy payment information.Main frame by wideband power carrier channel perform Modbus agreement, and one or more from
Machine carries out communication, reads and return the reading information of intelligent electric meter, is connected by power receptacle on wall,
Without wiring, it is suitable for domestic consumer.Main frame has reception user's input simultaneously, shows user profile, and leads to
Cross Net, WiFi or 3G data feedback channel domestic consumer's information to be automatically updated in main website, it is achieved pay and fault
Report automatization for repairment.
Having RS485 master port and power carrier communication port from facility, its function is that data process and agreement turns
Change.Perform the embedded program of solidification from the MCU of machine, advised by the agreement running electric instrument interface accessing
About, electricity usage state and equipment state are read.This machine responds the visit from power carrier communication port simultaneously
Ask request, send to the access information that main frame needs.
User reads status information and the arrearage information of equipment by the display interface of main frame, and audible-visual annunciator carries
Show that output is strengthened the directly perceived of man machine interface further and understands.Equipment is run shape by 3G/ broadband interface by main frame
State and electric fees charging state are reported and submitted to main website so that power equipment operator and electricity service provider are accurately real
Time understand User Status.
In a word, the foregoing is only preferred embodiment of the present utility model, all apply for a patent according to this utility model
