ABSTRACT
With the development of computer technology has been rapid development, problems of Taximeter MCU can not only solve the electronic system miniaturization, low power, high reliability and so on, and its development cycle is short, less investment, development of software chip prices continued to decrease. The design of the hardware cost is mainly composed of AT89S52 single chip microcomputer, LCD module, Holzer velocity measurement module, memory and calendar time module, analyses the working principle of the meter, and uses proteus simulation software design and debugging of the schematic design, the application of the meter software. The debugging results achieved the intended purpose. Provides a hardware and software design scheme is valuable for the actual production.
