1、摘要在水泥的生产过程中，回转窑是实现水泥熟料煅烧的核心设备，决定窑能否优质、高产、低消耗地生产熟料和安全运转的关键因素是窑衬。因此,在窑运转过程中,及时了解窑状况,防止窑衬及窑筒体损坏是回转窑经济运行的重要保证。窑筒体表面温度经处理分析后能客观地反映窑状况。该系统通过红外测温扫描仪对窑筒体表面温度连续在线实时监测、分析预测,防止由于过烧等各种原因造成的窑衬及窑筒体损坏,达到提高效益的目的。本文介绍了一种基于单片机的红外线测温系统，该系统由上位机和下位机两大部分组成。本设计主要完成下位机部分，下位机采用与8051兼容的高性能、高速单片机—STC12C5A16
2、AD为控制器，安装在无刷直流电机上的红外测温扫描仪高速旋转，完成对水泥回转窑窑体温度的数据扫描，然后通过前置放大器将红外扫描仪采集的数据经放大后，送至ADC进行模数转换，且系统与计算机通过MAX-485 通讯，将采集到的温度数据传输到上位机处理。该系统通过红外测温扫描仪对窑筒体表面温度连续在线实时监测、分析预测,防止由于过烧等各种原因造成的窑衬及窑筒体损坏,经处理分析后就能客观、及时地反映窑状况，从而达到保障生产安全，提高效益的目的。关键词STC12C5A16AD，AD转换，485串口通信，红外测温AbstractInthecementproduction
