Animal blood
analyzer, perspective
machine have their respective circuit system, clinical biochemical analyzer is
not exceptional also, the following is clinical biochemical analyzer circuit
system detailed analysis.
As shown in figure clinical biochemical analyzer using a piece of 2051 single-chip microcomputer control a stepping motor direction, speed, the rotation steps, etc., through the 422 difference serial bus will they connected to interface circuit, interface board control signals to through the single chip computer 8051 serial interface and the computer RS - 232 serial associated. All motor work in 24 v direct current, the position sensor is photoelectric sensor.
Semi-auto biochemistry analyzer and sample arm control circuit mainly by two stepper motor to control the mechanical arm rotation and lifting, four position sensor were detection elevator and rotational position, liquid level sensor testing sample and reagent level.
Data acquisition circuit using eight independent preliminary circuitry respectively each amplification of photoelectric sensor signal, 16 A/D conversion the analog signals into digital signals, guarantee in the absorbance to 2 when A resolution of 0.67 mA.
