基于单片机的胴体红外测温系统设计.doc

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,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内状况。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的红外线测温系统，送至AD进行模数转换，且系统与计算机通过?通讯，将采集的数据传输到上位机处理。,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、及时地反映窑内状况，Abstract In the cement production process, rotary kiln is to realize the core equipment of cement clinker pellets，the decision whether kiln high-quality, high yield, low production of clinker and security is a key factor in the operation of the kiln lining. So, in the process of kiln operation, the kiln to keep abreast of the situation, to prevent the kiln lining and the kiln is a rotary cylinder damaged an important guarantee for economic operation. Surface temperature of the kiln shell analysis can be treated objectively reflect the situation in the kiln. The system through infrared temperature scanner, the surface temperature of the kiln shell for online real-time monitoring, analysis and forecast, prevent burn-off caused by a variety of reasons, such as furnace and kiln shell lining damage, to improve benefits. In this paper, a MCU based on infrared temperature measurement system, the system consists of upper and lower machine composed of two major parts. Completed the design of the main part of the next-bit machine, the next-bit machine with a 8051-compatible high-performance, high-speed single-chip-STC 12C5A16AD controller, Brushless DC Motor installed in the infrared temperature scanner, high-speed rotation, the completion of cement rotary kiln temperature data from scanned, and then through the pre-amplifier will be infrared scanner data collected by the amplified, sent to ADC for analog-to-digital conversion, and system and computer through the MAX-485 communications, the temperature data collected transmitted to the Host Machine. The system through the infrared temperature scanners surface temperature of the kiln shell for online real-time monitoring, analysis and forecast, prevent burn-off c
