Design Of The Analyzer System For Food Safety Base On ARM Embedded-system

In this thesis, the basic principles and the significance of the food safety analysis technology were introduced firstly. After this, a design of the Analyzer system for food safety base on the ARM embedded processor was also expressed. In a word, there were three main aspects were researched in this paper. Firstly, desinged the electric drivers of the lamp, signal amplifier and analog-to-digital converters (ADC).Instrumentation amplifier and 24-bit ADC were used in signal detecting system to improve the SNR of the detection system,guaranteed the precision of measurement. Second, desinged the control electric circuit of the analyzer based on ARM embedded-system. Third, uC/OS-II and UC/GUI were ported on the control board, on the other hand, application software was developed and they could be run stably when they were tested.Also, in this thesis show the sample produt performance including the stability of the signal, gage of repetitability was tested as well as industry marketing trend. And the results showed that it could easily satisfy the request of the foods safety analysis, the food safety test requirement market is large as well...
