【摘要】 光学玻璃除在工业和军事领域作为重要的镜头材料,因其透光度高,色泽明亮,随着人们生活水平的提高,越来越多的被用于制作精美的工艺品,但由于生产过程化学反应过程复杂、反应温度高造成的现场环境恶劣使得自动控制技术的探讨到实践之间存在较大的鸿沟难以逾越。 当今玻璃工业新技术发展主要表现在两大领域:平板玻璃工业新技术研发方向及深加工玻璃新品种的开拓,本文采用趋于流行的嵌入式控制器来应对高效高精度低耗玻璃工业生产控制要求。 PCC(Programmable Computer Controller)即可编程计算机控制器,它的核心大多基于ARM Core,本文从ARM微控制器的工作模式来说明它的工作原理和适应运行实时操作系统的若干特征,并对本文选用的开发板的片上外设进行剪裁,来适应针对本系统的特定应用需求。并简述实时操作系统的主要概念、任务调度和针对本微控制器的移植,以阐明操作系统相对结构化程序在开发和维护方面的优越性。 本系统实现在原有工业现场设备基础上的改造,采用的气电传感部件能够克服现场的高温环境,实现连续的自动化作业。通过借助MATLAB SIMULINK库的强大数学演算能力,针对与本系统类似的滞后环节进行控制仿真,研究并比较了模糊PI算法和单神经元PID控制算法,为现场参数整定提供了参考依据。更多还原

【Abstract】 Optical glass which is widely used in industrial and military fields as lens material, featured by its transparency and brightness, as the living demand expanding, more and more being made into beautiful artifacts. But for its complicated chemical reaction in production, and high temperature makes the factory field uncontrollable, result in a big gap between theoretical research and field practice.Nowadays the development of glass industry immerses mainly in two fields: Research of new technology in flat glass industry and Expansion of way to deeply process new kinds of glass. This article using popular imbedded controller to fit the high efficiency、 high precision、 low consumption demands of modern glass industry.PCC stands for the Programmable Computer Controller, mainly based on ARM core, this article describes its work mode to introduce basic principle and some characteristics that matches the fundamental condition of RTOS, then according to the specific appliance, adjusted the on chip peripherals. Additionally introduced basic concepts of RTOS、 context switch and transplant to the target board, to show us the superiority in development and maintenance of OS compared with structured program.This system rebuilding on original industrial apparatus, the chosen pneumatic and electrical probe can stand the high temperature working environment, to realize continuous automated production. At last resort to the powerful math too-MATLAB, simulated the control of delay component, studied and compared the Fuzzy PI algorithm and Single Neuron PID algorithm, to make preliminary theoretical preparation for field parameter adjustment.更多还原
