Abstract:
Automatic biochemistry analyzer is a necessary instrument for clinical diagnostics. In this paper, a new scheme of concentrated control system for Automatic biochemistry analyzer based on FPGA (field programmable gate array) is put forward. As an important part of automatic biochemistry analyzer, motor control system is one of key parts. In the light of the problems of stepping motor in application, such as surge at low frequency, low torque at high frequency and bad frequency characteristic, the paper presents a kind of practical method of the constant flow chopping subdivision driving based on FPGA. This scheme solves oscillation of stepping motor, improves the control system of biochemistry analyzer instrument.
