Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
As shown in Figure 1, a kind of real-time calculation charge system for electric power, including database server, application server, encryption
Front server and storage equipment, using distributed B/A/S multi-tier systematic structure, to database server, application server
Layering deployment is carried out with client；
Database server: it is carried out for saving the electrical energy parameter of electric energy meter acquisition, and according to the data of electric energy meter acquisition
Real-time update；
Application server: expect that the data in the smart card of configuration setting are written and read to electric energy meter, and face is provided
To the operation interface of client；
Encryption front server: being connected between database server and application server, and user answers smart card insertion
After server, user using application server to storing that corresponding parameter accesses in database server when, need
The read-write of smart card is completed by encryption front server；
Store equipment: for the data in backup database server.
It is paid the fees when user's power purchase by cash and pay-in slip clearing form, forms purchase after payment amount of money and the adjustment amount of money are cumulative
Electric fund power purchase fund and power purchase number is written in smart card, printed tickets；When user's power purchase system need to old table whether
The clearing electricity charge are verified；It is paid advance when user's power purchase, the common of user advance can be switched to by adjusting the electricity charge
Power purchase fund is written in smart card；When the adjustment electricity charge are that difference occurs for the advance remaining sum in the advance remaining sum of system and table, in order to protect
The advance remaining sum of card system is consistent with residual amount in table, this part flow indicator calculates is come out and is adjusted to user, the original of difference
Because being divided into three classes: normal adjustment, system call interception and special adjustment；Normal adjustment is referred mainly to common advance and is moved back caused by mending the electricity charge
Adjust the electricity charge；System call interception refers mainly to electricity charge algorithm difference, residual amount meter reading difference, supplements caused difference with money not in time；It is special
Different adjustment can carry out additional maintenance mainly to handle some special circumstances, and when power purchase is filled in table together, the special feelings
Condition refers to other situations in situation described in normal adjustment and system call interception.
Card table Electricity customers are to clerk counter or have the site of withholding of sale of electricity read-write card equipment to carry out power purchase, if it is dress table
First time power purchase afterwards, user need first to carry out hair fastener business there are no smart card (power purchase card), will be in user information write-in card.
User provides media card and carries out power purchase, and system card reading obtains user information, calculates the adjustment because changing the generation of the factors such as table, zero passage
The electricity charge provide two kinds of funds source mode power purchases:
By the payment of the clearing forms such as cash, pay-in slip when this power purchase of user, after payment amount of money and the adjustment amount of money are cumulative
Power purchase fund is formed, power purchase fund, power purchase number are written in card, printed tickets.If the preset electricity charge of user's dress table are being flowed
Cheng Huanjie is not collected, and to be collected together in first time power purchase.
It needs whether to settle accounts the electricity charge to old table when power purchase and verify.
It has paid advance when user's power purchase, advance can switch to the common of user by adjusting the electricity charge by other means
In power purchase fund write-in card.
When the adjustment electricity charge are that difference occurs for the advance remaining sum in the advance remaining sum of system and table, in order to guarantee that system is advance as far as possible
Remaining sum is consistent with residual amount in table, this part flow indicator calculates is come out by algorithm and is adjusted to user by system, difference
Reason can be roughly divided into three classes: normal adjustment, system call interception, special adjustment.
Normal adjustment refer mainly to other approach it is common it is advance, move back and adjust the electricity charge caused by mending the electricity charge, for example, for other
Approach pay it is common it is advance can be filled in card as the adjustment electricity charge, and switch to power purchase fund.
Difference caused by system call interception refers mainly to electricity charge algorithm difference, residual amount meter reading difference, supplements with money not in time etc., example
As being to be deducted in real time by electricity, and marketing system calculating is according to meter reading periodicity extraction electricity when calculating ladder in table；In another example
The electricity time irreversibility of residual amount meter reading lag and the computing system electricity charge；In another example plug-in card is supplemented with money not in time after power purchase, and
At a time when meter reading day, the residual amount before only having copied back power purchase.
Special adjustment be mainly be to handle some special circumstances, can carry out additional maintenance, when power purchase, is filled in table together,
Belong to handle special circumstances and an increased technological means.
Power purchase is rushed just:
There are no returning to be inserted through ammeter after user's power purchase, because the reasons such as charge mistake, printed tickets mistake need to remove also,
It can carry out power purchase punching just, it will be in the last time power purchase information write-in card before power purchase.
It should be noted that punching just must satisfy charge rush positive rule (such as the next day cannot rush just, cannot rush just after pay in
Deng), it is necessary to limit card does not have back to be inserted through ammeter.
Adjust the electricity charge:
Since, without the objective fact freezed, residual amount is a continually changing dynamic again in addition in residual amount table
Value, therefore the calculating of the electricity charge is adjusted, as without no matter all being deposited from electricity charge audit or the calculating of power purchase link under the cooperation of power purchase number
In some difficulties, it can not accomplish that very accurately, but under existing conditions the remaining sum of Biao Nei and system, which is not inconsistent, to be bound to deposit
, if be not adjusted to user, it is increasing to will lead to error, therefore adjustment is also necessary, it is advance with system
It being adjusted subject to remaining sum, adjusted value is intended merely to allow the remaining sum in the remaining sum and system of user Biao Nei closer to some forever,
Have a power failure more more acurrate.
Adjust electricity charge formula:
Fundamental formular: according to above principle, it is as follows to adjust electricity charge formula:
The electricity charge=available balance (system available balance)-remaining remaining sum (residual amount in table) is adjusted,
1, available balance=do not freeze advance total value-arrearage；
2, accumulated recharge amount after remaining remaining sum=the last time meter reading residual amount+meter reading.
1) accumulated recharge amount after meter reading when accumulated recharge amount=accumulated recharge amount-last time meter reading:
Formula illustrates: what the formula was most difficult to calculate is residual amount in table, since the residual amount in table is to occur in real time
Variation, and the clearing of user be it is rhythmic, the residual amount of system be all after the billing cycle offset according to user more than
Volume, therefore the adjustment electricity charge can only be adjusted with settling accounts for the period." accumulated recharge amount after meter reading " in residual amount calculating
It just assumes that after last time meter reading, the residual amount of meter, does not just have as user after all power purchase amount of money are filled in card
Have using electricity, then just should be as the advance remaining sum in custom system, without difference, system remaining sum and remaining sum in table are mutual
It offsets, then difference is aiming at the last meter reading residual amount.
Problem explanation: single household is handled when this formula power purchase, can mitigate pressure when electricity charge distribution, not by last
Whether secondary power purchase inserts the limitation of table, but is influenced by whether last time power purchase inserts table, if last time does not insert table,
The adjustment electricity charge that formula will lead to this mend the electricity charge to user more, although formula power purchase can entangle again after second of meter reading
Just, but for when it is a little late, but from the present analysis the case where from the point of view of, have no idea whether to supplement with money before judging last time meter reading,
But in order to reduce such situation, it is proposed that be still based on the above company, calculate simulation is specifically supplemented with money, take difference between the two minimum
's.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
