| This thesis introduces the principle and the whole syetem's structure of the magnetic anti-body immunoassay (MAIA) apparatus based on micro-processor. MAIA is a more advanced measure technology that measure contents of little incretions and tumor markers of bodies' blood serum and urine. This measure technology has many advantages than the traditional radioimmunoassay (RIA) method This apparatus is designed by applying MAIA and according as Lambert-Beer absorb law. In desiging, we combine absorbed spectrum analyse technic, electronical technic, computer technic etc together. The light source in the system is a special one. Its ray through a test tube is divided into three different wavelength rays by two spectroscopes. After photoelectric transformation, the MSP43F449 micro-processor samples and deal with transformed analog signals so as to deduct contents of little incretions and tumor markers in blood. These incretions and tumor markers can provide important proof for doctors diagnosing correlative disease. The measuring result can be printed and displayed through output equipments. Users can operate and control to this apparatus by using the panel keyboard. The thesis provides some hardware circuit diagrams, software flow charts and operation guide of the apparatus. |
