Abstract: The gauge detection between high signal and contact net is an important part in railway safety production. According to the detection nature, this paper designed a visual detection system to solve the problem of gauge detection between high signal and contact net. Using template matching method to break up the gray target image, and using discovering turning point method to rebuild target in space. Then according to the principle, it prepared detection system based on VC++2008 and OpenCV. The experiment results showed that: measurement error was within士15mm, when detection distance was arrange from 45.0m to 55.0m. Detection system which had high accuracy and good reliability, met system design requirements.

Abstract: Traditional coating shell marking process is complex, has long production period, high labor intensity, and endangers health. In order to solve these problems, this paper studied and designed a kind of automatic production line of precision molding in coating shell making process. The production line was controlled by a single-chip microcomputer to automatically achieve the process of dipping, sanding, hardening and drying. It not only improved work efficiency and saved labor, but also reduced the body harm of workers.

Abstract: It plays an important role to detect gauge between high signal and contact net in railway safe, to provide safe guarantee for railway workers. This paper proposed a visual detection model to solve the problem of gauge between high signal and contact net. Base on three-dimensional reconstruction high signal and contact line with space points, it transformed two objects coordinate, then analyzed the position relationship and accurately solved the shortest distance from high signal to contact line, last compared with the standard gauge to achieve the process of gauge detection.

Abstract: Study on the preparation processing of E-ACE.By experimental methods, the conductivity, the mechanical flexibility of the electrode material and the thickness of the acrylic polymers were studied respectively. Experimental results show that the conductivity of electrode material have an impact on the performance of E-ACE, E-ACE performance is enhanced with the increasing of conductivity of the electrode material. Mechanical flexibility of Electrode materials and thickness of acrylic polymer have significantly impact on the performance of E-ACE, E-ACE performance is enhanced with the decreasing of mechanical flexibility of electrode material, and E-ACE performance is also enhanced with the decreasing of the thickness of acrylic polymers.
