Novel Man-machine Interface of Intelligent Leak Detector for Advanced Material with Material Properties in Fuel-gas Pipe Based on Electrical Power System

摘要

The advanced material has been used extensively in various engineering in recent years, especially in the fuel-gas pipes. The material properties are always under the influence of a variety of factors, such as different levels of the manufacturers, the manufacturing process and so on. Although many countries have strict supervision to the material properties of fuel-gas pipes, but the pipe leak is inevitable. So the leak detection has important meaning in the field test experiment of pipes' material properties and the practical engineering. In order to solve the problem of interaction between the fuel-gas pipe leak detector and the users, a man-machine interface is designed based on electrical power system. The hardware mainly consists of the microprocessor, the input circuit and the output circuit. The software of interface is realized with the embedded C language, and it mainly consists of the input program and the output program. Experiment results show that the man-machine interface can accomplish the interaction between the user and the detector for advanced material with material properties in fuel-gas pipe splendidly; and it has a good application prospect.
