Linfu Ban
Abstract: A solution to the IC card intelligent fuel-meter is put forward. The IC card intelligent fuel-meter is a high-tech civil product which can not only compute the fees according to the quantity of fuel used but also control the use of fuel automatically, taking a grate advantage over the traditional manual reading fuel-meter. It is designed by adding an intelligent measuring and controlling system which mainly consists of system circuit of SCM, a flux sensor, a memory, a power-efficient valve, a power circuit, an IC card fitting, a real time clock, defend the magnetic needle guard against theft mold piece ,a LCD monitor and a controlling valve of the pipe of gas to the common used fuel-meter. And the principle block diagram, the power circuit, the interface circuit and software flow of the IC card intelligent fuel-meter are introduced. This product has power efficiency, good security and high reliability.
Key words: IC card intelligent fuel-meter hardware and software SCM
