| Abstract: | IN this thesis, a brief introduction was given to the basic principle and method of multichannel Biochemical Analyzer. The hardware and software of measure and control system were designed based on ATmega128 MCU and A/D converter in ATmega128 was adopted in analog input channel and 4MB high speed SPI Flash memory was expanded. The application of the logarithmic am-plifier LOG112 realized the absorbance measurement of hardware. The experimental results show that the detector has the features of speediness, reliability, veracity and better maneuverability etc. It can simultaneously complete the data test of many wave lengths and enhances the analysis speed. |
