The expansible submodule of information acquisition system main website is dedicated for the storage all kinds of numbers related to user's intelligent miniature breaker
According to, then an external interface is provided to the teller system set up in advance.Teller system can be using mobile phone A PP, micro-
The modes such as letter public number registered for the owner of intelligent miniature breaker and logged in after family information, and user will be provided with inquiring about, set
Put, control three kinds of function privileges.
Under query function, electric current, the work(of respectively using electrical circuit that user can check that oneself house is overall and install switch-dividing
Rate, accumulative active energy amount, current active energy amount situation；In the case where setting function, user may choose whether to upload load curve
Automatically whether data, the activity of participation Demand Side Response, load cut down priority（Which preferentially cuts off and draws electrical circuit）Deng.If with
Above-mentioned option is opened at family and intelligent miniature breaker is in automatic control mode, then one or more in user family uses electrical circuit
Will automatically it be disconnected in specific time period, the automatic reclosing after the response period terminates；Under control function, if intelligent miniature breaker
In automatic control mode, user can voluntarily select any bar of premises to be turned on and off with electrical circuit, realize that multiloop is long-range
Divide-shut brake.
It can be recognized to turn into intelligent miniature breaker by concentrator, communication protocol between the two need to be pre-defined.Cause
Current intelligent electric energy meter uplink communication stipulations《DL T 645-2007 multifunctional electric energy meter communication protocols》（Hereinafter referred to as DL/T
645）It is compatible with power information acquisition system depth, it is contemplated that intelligent micro intelligent breaker is with electric energy meter in the whole frame that communicates
Position is similar in structure, can refer to the uplink communication program that above-mentioned stipulations write MCU, realize intelligent miniature breaker and concentrator it
Between data communication.
Because concentrator belongs to grid company assets, therefore the expansion scheme of main website and concentrator communication protocol need to be proposed,
Make it to recognize the polymorphic type electricity consumption data from different user intelligent miniature breaker, and identify all kinds of under same breaker
The corresponding branch's electrical circuit of data.
In the uplink communication agreement of current concentrator《Q/GDW 1376.1-2013 power user power consumption information acquisition systems
Communication protocol part 1：Main website and acquisition terminal communication protocol》（Hereinafter referred to as Q/GDW 1376.1）In, with application level function
Code AFN definition command types, information point identification pn defines different operating object, and info class mark Fn defines different information types.
, need to be to arrange parameter order to meet demand（AFN=04H）In " terminal electric energy meter/ac sampling device configuration parameter "
（F10）It is defined extension.The measurement point can be used to declare for intelligent miniature by constant value defined in " traffic rate and port numbers "
Breaker；6 byte mailing addresses of the breaker master switch defined in " mailing address " and all switch-dividings；" affiliated to adopt
Storage mailing address " defines different value to distinguish different user；0 is always to open defined in " the big class-mark of user and the small class-mark of user "
Close, other values represent the switch-dividing of each branch's electrical circuit successively.Thus realized in concentrator aspect micro- to different user
The unified management of different switch-dividings under type intelligent breaker and same user's breaker master switch.
Because electric current, voltage, power, electric flux, load curve data etc. have had corresponding in Q/GDW 1376.1
Fn is clearly identified, therefore without carrying out communication protocol extension to energy data type again.And divide-shut brake etc. controls generic operation in DL/T
Had been defined in 645, therefore main website only need to perform data forwarding order to concentrator（AFN=10H）In " transparent forwarding "
（F1）, you can realize that intelligent miniature breaker voluntarily responds remote control.
It is the main flow chart of intelligent miniature breaker software systems as shown in Figure 5.Software systems are divided into system initialization journey
Sequence, control model discriminating program, divide-shut brake control program, data sampling program, data processor is data display program, logical
Several parts such as letter program.
After system electrification initialization, software systems first determine whether whether killer switch is in "on" position, if being in
Gate-dividing state, then will not run remaining program before switching to close a floodgate.After breaker closing, system adopts the automatic data that perform
The programs such as sample, processing, display and communication, and whether monitoring electrical circuit there is exception in real time, once it is determined as exception, it will it is vertical
Perform divide-shut brake control program cut-out problem circuit.Under normal circumstances, it is excellent for highest with the manual divide-shut brake operation of user
First level, the manual brake separating of user will interrupt the execution of all programs；When user is not operated manually, control model differentiates
Whether program will judge breaker in automatic mode.If automatic mode, then with reference to user site for service set it is long-range
Control parameter, once receiving long-range divide-shut brake order, it is fixed that breaker will perform the automatic division of divide-shut brake control program
Use electric line；If manual mode, then breaker normally performs remaining program in addition to divide-shut brake, but is not responding to any long-range control
System order.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model know-why is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as protection domain of the present utility model.
