摘　　要：AVR单片机具有高可靠性、高性能、低功耗等特点,被广泛应用于工业控制之中。针对1024个密集文件柜状态监测问题,自主研发了以AVR单片机为核心的状态监测系统,实现对文件柜内有无存放物体以及何种物体进行管理。本系统包括文件柜状态检测、数据采集、ModBus通信、上位机组态等部分。本系统结构简单,稳定性、可靠性高,成本较低,具有很高的应用推广价值。Featured in high reliability and performance and low power consumption,the AVR single-chip microcomputer is widely used for industrial control. With regards to state monitoring for 1024 densely loaded file cabinets,we have developed on our own a status monitoring system using AVR single-chip microcomputer as the core to keep informed on whether there are deposits in the cabinets and what they are. The system contains different parts,such as those for cabinet status monitoring,data acquisition,Modbus communication and host computer configuration. It has a simple structure,high stability and reliability and low cost,and is highly worthy of popularization.
