Design of intelligent IC card gas meter
abstract In the era of the rapid development of information technology, people's production and life and tend to intelligent, intelligent high-tech products continue to be R & D and innovation. In these products IC card technology for people's life brought great convenience, IC card due to its inherent information security, easy to carry, perfect the advantages of standardization, in identity authentication, banking, telecommunications, public transportation, yard management is more and more application. The system design is the use of IC card design a kind of intelligent gas table to realize the pre charging function, in order to solve the problems existing in the traditional charging mode for gas management and Household conveniences. The design of single-chip microcomputer detecting control core, unifies the IC card, LCD liquid crystal display, electric valve to control, gas flow detection and external memory to complete a intelligent IC card gas meter.
The main work and research of this system includes the following parts:
Careful study of the various manufacturers of smart IC card gas meter, analysis of their respective advantages and disadvantages, and then according to the actual needs of the overall design of a preliminary outline.
According to the function and the characteristics of the design to determine the various modules used in various components of the model, in order to improve the practicality, economy and reliability of the product.
Each module of the system hardware circuit design to complete the design of the various functional requirements of the product, and draw the entire system design schematic.
The software design of the system, the preparation of the various modules of the program to complete billing function, display function, IC card reading and writing function and fault alarm function.
Key words: IC card technology intelligent gas meter single chip microcomputer technology solenoid valve technology memory technology
