The Software Development Of Mould Oscillation Detection And Analysis System

The mould is one of the key devices of continuous casting machine, and the yield and quality of continuous casting machine mainly depend on the oscillation of mould. Therefore, it is quite significant to design an oscillation detection and analysis system of mould. The subject of this project is "Mould Oscillation Detection and Analysis" in a large domestic steel enterprise. After fully study in domestic and abroad mould oscillation detection systems, analyzing the shortcomings of existing detection systems, and combined with actual demand of mould oscillation detection, a new set of mould oscillation detection and analysis system, which had real-time detection and fault diagnosis functions, was presented. The specific design was finished.The system was divided into two parts: handheld and PC. Handheld part based on the MSP430 and Pocket PC was a field detection equipment, and PC part was a data management and analysis system based on Windows operating system platform. This system could not only detect mould oscillation at the scene, but also analyze the historical data. The results would guide the future continuous casting.The dissertation introduced the design of the handheld part and the PC part in detail. During the software design, the multi-thread technology, a new data management scheme of cooperating data management with database system and file system, multi-signal analysis methods and MATLAB engine, were applied. Based on the actual requirements of mould oscillation detection, the handheld system played the online detecting role, which showed the time domain map, frequency domain map, axis track map and parameters of the vibration signal, and saved the data in accordance with request; while the PC system managed the saved data and analyzed the data. The system had a good human-computer interface, easy-operation, portable and other advantages.To improve practical working ability, design scheme and functions of system, developer made numerous testing experiments. Experiment results proved that, during the vibration signal detecting process, system run stably and supply accurate detecting results. It had a good application prospect.
