Management method and system capable of using gas with time and quantity limit

Abstract

The invention relates to a management method of using gas in limited interval and limited amount and a system, which relates to a gas supply management method and a system in a gas supply management industry, and comprises four portions which are a novel gas meter, a gas information card, a reading and writing card device and a computer management software. The invention overcomes the contradiction that gas bill is difficult to take over in a mode of charging after gas supply management first, overcomes many contradictions in a prepayment gas supply mode, and is a novel and original gas supply management method. The novel gas meter is equipped with measurement, a clock and an IC card holder, use expiration date and an authorization gas used amount can be read from the gas information card, gas amount can be copied to the gas information card, and gas can be controlled to make and break. The gas information card is a vector to transport the use expiration date and the authorization gas used amount and copy a user gas used amount back. A computer management system can achieve that user information is managed, the gas used amount which is read back is stored in a database through the reading and writing card device, and new use expiration date and the authorization gas used amount are written in the gas information card.

Description

technical field [0001] The present invention relates to a time-limited and limited-use gas management method and system, in particular to a gas supply management system consisting of four major parts: a new gas meter, a gas information card, a card reader device and a computer management system. Air management methods and systems. Using the gas supply management method and system of the present invention, the gas supply management department can authorize the gas usage amount and the usage deadline to the user according to the credit degree of the user, and can realize the self-checkback of the gas amount that has been used, for The gas supply management department provides an effective and advanced method of gas fee settlement and gas supply management. Background technique [0002] At present, the gas charging method is generally to charge after the supply. The phenomenon of arrears of gas fees is more serious, and the amount of gas fees in arrears is also relatively larg...
