Design and Realization of Bus Automatic Reporting Station System

In this paper, based on the traditional bus stops system, combining with the characteristics of the use of public transport vehicles and the actual operating environment, design a kind of bus stops are automatically controlled by the single chip microcomputer system, this paper introduces the system at the start of the overall design thought, after detailed research and analysis is mainly focused on the two aspects of hardware and software design of the whole system. Hardware, use AT89C51 single chip microcomputer as controller, makes the design of the hardware system simplification, the system hardware design including keyboard circuit and reset circuit, display driver circuit, display circuit, memory expansion circuit module. Application software, KeilVision4. Write the main program, using the modularization and the top-down design concept to achieve the single chip microcomputer control of the various modules, in detail the design of each part of the application. At the end of the paper, the software and hardware debugging of the whole system is briefly introduced and summarized.
