【Abstract】 In the nuclear power industry, the internal inspection of the containment can directly reflect its performance, which is a very important task. At this stage, the bulge measurement of the containment lining in the internal inspection is mainly carried out by manual measurement. Aiming at improving the efficiency of the traditional method, a new system for bulge measurement has been developed in this paper. This system is developed based on the Raspberry Pi platform, using laser displacement sensors and ultrasonic ranging sensors to realize automatic measurement and identification of the containment bulge, which can improve efficiency and reduce costs. In addition, the design experiment is carried out to analyze the accuracy of the system. The example shows that the measurement accuracy of the system is better than the requirements of the internal inspection, which shows that the system is practical and feasible.更多还原
