河南科技学院2010 届本科毕业论文（设计）论文题目：基于单片机粮库温度监控学生姓名： 范志愿所在院系： 机电学院所学专业： 应教101导师姓名： 张素君完成时间：2015 年 月 日摘 要本课题设计的是粮库监控系统,是对各个粮库的温度进行监控,以保证粮库储粮的安全。粮库监控系统以STC12C5A60S2单片机为核心构成温度监控系统。一个STC12C5A60S2单片机分机负责一个粮库的温度监控任务,一片STC12C5A60S2上挂多个温度传感器DS18B20，分机与主控机的通信采用485通讯总线方式,无线通讯对发送数据进行CCR校验和独特的编码,提高了数据传输的可靠性。无线传输避免了远距离布线所带来的损耗大,成本高的缺点。由工控机直接通过串行通讯读取主控机处理后的数据,进行集中图形显示。关键字：STC12C5A60S2，温度监控，DS18B20Abstract本课题设计的是粮库监控系统,是对各个粮库的温度进行监控,以保证粮库This topic is the design of the monitor and control system, is to monitor each grain storage temperature, to ensure the grain depot Grain Storage safety.The monitor and control system based on MCU of STC12C5A60S2 temperature control system. Temperature monitoring tasks of a STC12C5A60S2 SCM is responsible for a food bank, a piece of STC12C5A60S2 to hang a plurality of temperature sensor DS18B20, the extension communication with the main control machine uses 485 communication bus, wireless communications CCR checksum and unique code to send data, improve the reliability of data transmission. The wireless communication can avoid loss caused by long-distance wiring, high cost. By the computer directly through the serial communication to read master data, centralized display.Keywords: STC12C5A60S2,Temperature monitoring， DS18B20目 录摘 要 .....................................................
