Abstract-Based on the practical teaching requirements of metallurgical engineering, a cold position training device on the melter gasifier was designed in line with actual production. The control system adopts the integrated control cabinet and its design of the training device is implemented by the PLC of Siemens S7-300 and the configuration software of Real Bridge. The control mode includes two kinds of modes, which are remote control and manual control. Through the development and use of the melter gasifier training devices, the teaching content can be visualized. This device has been put into use in colleges, and obtained the good training effect.

Solar tracker is an important part of photovoltaic generation and solar heating system. By solar tracker, the efficiency of solar utility can be significantly improved. Considering the camera device is widely applied in the photovoltaic generation and solar heating systems, based on the visual motoring equipment, a kind of solar tracker is designed. Using the proposed solar tracker, the height and the angle of the sun can be detected and be applied in solar tracker controller. Experiments show this design has relatively high accurate rate during a week’s period while the weather are partly cloudy or clear. It shows good application future in photovoltaic generation and solar heating industries.
