【摘要】：在石油炼化行业中,为了最大程度地提高石油的利用率和产品质量,降低能耗,节省原材料,除了不断引进先进的控制系统外,还要求炼厂有与之适应的监控系统和检测仪表,保持生产过程的随时被监控,处于最佳状态。而在线油气分析仪在石油化工中有着广泛的应用,对石油化工企业的正常运行有着重要的作用。国内使用的油气分析仪表多数来自于国外,价格昂贵,适应性差,维护困难。本课题的主要任务是设计开发基于STM32F103单片机的油气分析仪的人机界面以及基于线阵CCD的实验研究,以满足基于近红外光谱的油气性质分析仪表低成本、高性能的需求。本文的主要内容是:首先,根据油气性质分析仪表的总体结构特点与工作原理,设计油气分析仪人机界面的总体设计方案,分析油气分析仪人机界面的特点与设计目标,构建人机界面系统开发平台。其次,根据人机界面的开发需求,按功能需求详细介绍人机接口开发的各部分设计方案,以及实现主控制器STM32F103单片机与PC机中的LabVIEW界面的USB通讯,与可编程触摸屏界面的RS-485通讯,实现完整的人机界面体系。最后,对人机界面系统进行整体的调试。然后进行一系列基于CCD的数据采集实验,为后续的近红外油气光谱定量分析打好基础。
[Abstract]:In the petroleum refining and chemical industry, in order to improve the oil utilization ratio and product quality to the greatest extent, reduce energy consumption, and save raw materials, in addition to the introduction of advanced control systems, refineries are also required to have suitable monitoring systems and testing instruments. Keep the production process monitored at any time and in the best condition. The on-line oil and gas analyzer has been widely used in petrochemical industry and plays an important role in the normal operation of petrochemical enterprises. Most of the oil and gas analysis instruments used in China come from abroad, which are expensive, poor adaptability and difficult to maintain. The main task of this paper is to design and develop the man-machine interface of oil and gas analyzer based on STM32F103 single chip computer and the experimental research based on linear array CCD to meet the demand of low cost and high performance for oil and gas property analysis instrument based on near infrared spectrum. The main contents of this paper are as follows: firstly, according to the overall structure and working principle of the oil and gas analysis instrument, the overall design scheme of the man-machine interface of the oil and gas analyzer is designed, and the characteristics and design objectives of the human-machine interface of the oil and gas analyzer are analyzed. Build the man-machine interface system development platform. Secondly, according to the development demand of man-machine interface, the design scheme of man-machine interface development is introduced in detail according to the function requirement, and the USB communication between the main controller STM32F103 MCU and the LabVIEW interface in PC machine is realized. Communicate with the RS-485 of the programmable touch screen interface to realize the complete system of man-machine interface. Finally, the man-machine interface system is debugged as a whole. Then a series of data acquisition experiments based on CCD were carried out, which laid a good foundation for the quantitative analysis of near infrared oil and gas spectrum.
