2. the prepayment center separates the metering function from the charging function, the meter end is responsible for metering and data uploading, the charging is not carried out, the center settles accounts according to the uploaded metering data, the center realizes the functions of step charging, periodic settlement, preset gas price and the like, the charging function of the mode completely depends on the center, when the meter end and the center can not normally communicate, the meter end can still be normally used, but the center can not obtain the use information, the charging can not be carried out, and the company is lost.

Disclosure of Invention

The invention aims to: aiming at the problems in the prior art, the method for realizing prepayment by taking central charging as main meter-end auxiliary charging is provided, and the problems that the procedure of the prepayment meter-end charging is complex, the charging completely depends on the meter-end, the meter-end fault charging data is lost and the prepayment center charging completely depends on the center, when the meter-end and the center can not communicate normally, the meter-end can still be used normally, but the center can not obtain the use information, and the charging can not be carried out are solved.

The invention aims to be realized by the following technical scheme:

the method for realizing prepayment by using central charging as main meter end auxiliary charging includes the following steps:

(1) the system center issues an account opening instruction and sets initial use parameters of the table end;

(2) after opening an account, the meter end charges according to the unit price of opening the account, and the valve is closed when the balance reaches a set value;

(3) the method comprises the following steps that a table end freezes data at a set time point every day, actively communicates with a system center, and uploads the frozen data, unit price information and equipment state information;

(4) the system center calculates balance according to the freezing data reported by the meter end, calculates the unit price of the meter end, if the calculated balance is not consistent with the freezing balance, the system center issues an instruction to correct the balance of the freezing time point in the meter, the meter end subtracts the accumulated energy of the freezing time point according to the current accumulated energy after receiving the correction instruction, recalculates the current balance according to the current unit price calculated by the system center, and returns the accumulated energy information and the balance of the current time point to the system center after the correction is finished.

As a further technical solution, the initial usage parameter includes an initial balance and a unit price.

As a further technical scheme, the closing of the valve when the balance reaches the set value is specifically closing when the balance is 0 or reaches the overdraft limit.

As a further technical scheme, the method for calculating the unit price of the meter end in the step (4) is that the accumulated gas consumption of the meter end of the gas meter exceeds the step gas consumption and enters the next pricing unit price; adjusting the price of the system; the step cycle time is reached and the base price is executed.

As a further technical scheme, in the step (4), when the calculated unit price of the table end is inconsistent with the unit price reported by the table end, the system center issues a price adjusting instruction to modify the unit price of the table end.

Compared with the prior art, the invention realizes prepayment by adopting a mode of taking central charging as a main charging mode and taking a meter end as an auxiliary charging mode, and has the following advantages:

1. the meter end program design is simple, only need according to can deduct the fee, need not relate to ladder charging and periodic charging problem, the charging data is preserved in the center, meter end trouble can not influence the central charging.

2. The meter end and the center charge, the meter end still charges when the network is abnormal, and the valve is automatically closed when the balance is 0 or the overdraft amount is reached, so that the problem that the offline meter can be used all the time and cannot charge is solved.
