[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.
