To detect blood clotting time and clotting absorbance efficiently,a kind of coagulation process parameters detection system used by coagulation analyzer was proposed based on Freescale MC9S12XS128 MCU.First of all,the basic idea of the op-tical detection method was explained and the corresponding structure and working principle of the optical detection device was in-troduced.After these,the corresponding photoelectric conversion circuit and signal conditioning circuitry were designed using halogen lamp as light source.Then,the scattered light data processing algorithms and transmit light data processing algorithms were given.At last,the blood clotting time and clotting absorbance were calculated based on the basic of the collected data pro-cessed with Matlab.Experimental results show that the hardware system and the algorithms are feasible and reliable.The whole instrument has a value of medicine.
