基于ATmega16 MCU的机车巡检装置的设计

Design of locomotive inspection device based on ATmega16 MCU

针对机车运行系统按时巡检的工作要求,设计了一种基于ATmega16 MCU控制的机车定时巡检语音提示装置,能够显示日历时间,设置巡检时间及录入和播放提示语音,具有较高的实用价值。本机车巡检装置由ATmega16 MCU作为主控芯片,DS1302与2片ZLG7289组成实时日历时钟的数字显示电路;ISD1760与TEA2025组成语音录放及音频功放电路;通过键盘电路可以对日历时钟进行设置及录入巡检提示语音。

Aimed at the demand of locomotive inspection for Locomotive Operation System on time, a kind of locomotive inspection device based on ATmega16 MCU was designed, which was able to demonstrate calendar time, set up inspecting time, record and broadcast hint pronunciation, and was with higher application value. The device was made of ATmegal 6 MCU, DS 1302 and 2 piece of ZLG7289 to form real time calendar clock digital display circuit. ISD1760 and TEA2025 were used to compose of circuit of voice recording and VF power amplification. The keyboard circuit could be used to set up calendar clock and record inspecting hint pronunciation.
