A MINI APPLICATION SYSTEM BASED ON SINGLE CHIP COMPUTER 80C31 IN A PROTABLE DATA CHECK APPLIANCE

本文介绍的是一个用８０Ｃ３１单片机构成的袖珍式应用系统。它可用作抄录数据，或查寻登记在案的数据。系统构成包括８０Ｃ３１单片机、可充电电池连续供电的１２８ＫＢ随机存储器、ＲＳ—２３２接口、５×４键盘、ＬＣＤ显示器。系统设计特别注意了成本低、体积小、耗电省等特点。文中对系统的硬件结构和原理作了具体说明，并简单介绍了软件部分。

in this paper a mini application system based on Single Chip Computer 80C31 is introduced. The system can be used for transcribing data or checking data which have been transcribed. It includes a Single Chip Computer 80C31, 128KB Random Access Memories (RAM) powered continuously by rechargeable batteries, a Series Interface,a 5×4 Key Board and a Liquid-Crystae Display (LOD). The design of the system is characterized by its low cost, tiny volume, low power consumption and portability. In the paper, the hardware structure and its principle of the system have been illustrated, and the software has been introduced.
