Abstract： This paper analyzed and summarized the technical requirements and conditions of gas step billing, and constructed a technical model of step billing algorithm. Innovatively this paper proposed a design method of dual billing schemes, and two sets of step billing plans were set up in the gas meter, one of the plans was judged to be the current run plan based on the effective date of the scheme. Compared with single scheme design, it reduces the complex processing requirements of modification, enabling, price adjustment and real-time clock timing of billing scheme. Finally, the functional requirements, system composition and charging test method of step billing gas meter were analyzed in detail, and a CPU card step billing gas meter with real-time step billing function was designed and developed.
Key words : step billing；gas meter；billing scheme；CPU card
