单片机自动电子地图

本文叙述用单片微型计算机(8051)控制的自动电子地图,它利用发光二极管作显示器件,由外接8255A的单片机8031系统和光电耦合管、继电器等外围线路组成控制部件。能自动显示中国地理课本主要的十六幅地图。它具有新颖、灵活、醒目、直观、动态闪烁及逐次分段显示等优点,对实现教学现代化,提高课堂教学质量将产生很好的效果,有一定的社会效益。

Chip Microprocessor Automatic Electron Map

An automatic electron map controlled by a chip microprocessor (8051) is shown here. It uses a photion as a showing part and a external circle as a controlling part which consists of a chip system 8031 connected by 8255A externally, a photo conductine effect and a relay. The main sixteen maps in the chinese geography textbook can be displayed by it automatically. The automatic electron map is novel and audio-visual with the advantages of flexibility, dynamic scintillation and showing by stayes, which is beneficial to society and has a good effect on the modernization of teaching and the improvement of teaching quality.
