The Research Of The Embedded System For On-line Process Analyzing Apparatus Base On DSP

With the development of the technology of the computer especially embedded system, the traditional analytical instrument is updating constantly. It is marching towards such directions as digitization, intelligent, informatization, networking, microminiaturization and solid state, etc. At the same time, there is certain disparity between the level of analytical instrument of our country and foreign like product. This still needs analytical instrument's researcher to make more untiring efforts. The subject is a further research based on homemade analytical instrument's digitized platform project of Nanfen Analytical Instrument Plant in Nanjing. This plays a certain role in further research of homemade analytical instrument's digitization, intelligent and microminiaturization. On the other hand, as a kind of embedded system, the analytical instrument requires us to follow the development situation and demand of the embedded system. Especially with the development of microprocessor and RTOS, we should study and apply them in time to catch up with and surpass the analytical instrument's development level in the world.According to intelligent platform for online multi-channel analyze instrument, the author did some research and designed the embedded intelligent platform for survey and control based on digital signal processor F2812, and analyzed the difference and capability characteristic between the platform based on 80196KC processor and platform based on DSP F2812. Furthermore, the direction of the characteristic extension for the platform in the future was brought forward. Presently, the author has achieved the junior system test for the platform based on DSP F2812. The paper mainly includes the following contents:Firstly, the definition and development of the analytical instrument are reviewed. The primary actualities and development points are introduced. The thesis discusses the development prospect of analytical instrument as the high-tech production and consequently advances author's research background and primary work.
