Abstract: Existing test methods for response time based on oscilloscope generally have many defects, including limited test sample base, large test data error, and low test efficiency, which do not meet the requirements of test preciseness and current industrialization development. To solve these problems, this research, based on the distributed test platform of multi-controller, designs an automatic test technology for response time based on synchronous triggering mechanism, through analyzing the existing test technology for response time of Distributed Control System (DCS) in nuclear power plant. Practice has proved that this automatic test technology for response time has technical advantages and practicability in the field of industrial control, and has high popularization value. -
