Intelligent gas meter price adjustment cost automatic price difference filling calculation method for IC card

Abstract

The invention provides an intelligent gas meter price adjustment cost automatic price difference filling calculation method for an IC card, and relates to the technical field of valuation checking. The method includes the steps that a gas meter master control MCU reads new price system information of the IC rechargeable card and records the information in a storage chip; the gas meter master control MCU generates corresponding accumulative gas volume of all scales and corresponding price under a previous price system according to the accumulative gas volume used by a user within the retardation time after new price takes effect; the accumulative gas volume of all scales of the new price system and the corresponding price under the new price system are generated again; the information is written into the IC rechargeable card. The technical problem that in the prior art, after the user buys gas with the gas meter rechargeable card in a service hall, the account of the meter gas volume issettled under the new price system, and the new price system and the previous price system are different and cause final settlement cost deviation is solved. The intelligent gas meter price adjustment cost automatic price difference filling calculation method has the advantages that in the process of buying gas for the user by the charging system, the recharging amount is adjusted according to the gas collected data, and gas meter settlement deviation is eliminated without affecting the original user operation.

Description

technical field [0001] The invention relates to the technical field of pricing and accounting, in particular to gas price adjustment and a method for calculating the gas cost difference before and after price adjustment by an IC card gas meter. Background technique [0002] With the rapid development of the gas industry, the gas company's demand for IC card prepaid gas meters has also changed from the original gas volume type billing to the amount type billing. The gas meter application amount-based billing method is to settle the fee in real time at the meter end, which can meet the gas company's charging demand for step-by-step pricing based on the user's gas usage. For the current IC card gas meter, the data interaction between the gas meter and the charging system completely depends on the IC card. For gas meters using the amount-based billing method, when the gas company needs to adjust the price at the meter end, it needs to use an IC card to adjust the price of all r...

Problems solved by technology

[0003] In order to solve the technical problem in the prior art that after the user purchases gas with the gas meter recharge card in the business hall, the gas meter is settled under the new price system, and the new and old price systems are different, resulting in deviations in the final settlement fee, the present invention Provides a calculation method for automatic compensation of price adjustment fees for IC card smart gas meters, supplements the existing amount-type prepaid IC card gas meters, and solves the problem of deviations in settlement fees caused by lagging price adjustments
