【摘要】 热处理是提高金属材料及其制品质量的重要技术手段。近年来随工业的发展,对金属材料的性能提出了更多更高的要求,因而热处理技术也向着优质、高效、节能、无公害方向发展。电阻炉是热处理生产中应用最广泛的加热设备,加热时恒温过程的测量与控制成为了关键技术,促使人们更加积极地研制热加工工业过程的温度控制器。本文以实验室热处理电阻炉炉温控制系统为背景,对原有几台电阻炉的温度控制系统进行技术改造。基于实验室的基本条件,设计了具有上、下位机的小型集散控制系统。上位机起到监控和信息管理的作用,具有通信功能,下位机实现基本控制、数据采样、控制输出、实时显示温度控制器运行状态和通信功能。控制器采用51单片机作为处理器,改型后的温度控制器具有自动检测、数据实时采集处理及控制结果显示等功能,控制的稳定性和精度上都有改进,温度控制器的面板简洁,操作方便,满足了本次改造的技术要求。更多还原

【Abstract】 Heat treatment is a main means of improving metal material and metalwork. In recent yeas, with the development of industry, there are more and more supernal request for metalwork, so heat treatment is hammering at high quality and efficient, low-power and zero-social effects of pollution. Resistance furnace is a used broadest heating equipment in heat treatment, and measurement and control of temperature in heating is becoming pivotal technic. These urge people study methods of controlling heating process.In this thesis,using the temperature control system of laboratory resistance furnace as the background to describe the technological transformation of the old equipment. Based on basic experimental conditions, we design the Distributed Control System(DCS). Host computer plays the role of monitoring and information management. Slave computer realizes basic control, data acquisition, control output, real-time display and communication functions. MCS-51 Single-Chip Microcomputer as a processor, the modified temperature controller possess automatic detection, real-time data acquisition and real-time display. The modified temperature improves stability and control precision, The control panel of temperature control system is very concise and convenient.The modified temperature control system satisfies technical requirements.更多还原
