Abstract
Due to the improvement of the living standard of the domestic people, the continuous progress of science and technology, constantly improve the control, so as to promote heliostat to become the leading of various rotating machinery industry. With the innovation of modern machinery towards high performance, automation and scale, heliostat is widely used in all kinds of large machinery and photovoltaic power generation, especially in large manufacturing and photovoltaic industry. In photovoltaic power generation system, heliostat plays an important role, and in order to maintain the service life of the instrument, it is necessary to do a good job of anti-vibration performance. Therefore, the new generation of us need to carry out relevant research on the performance parameters and functional parameters of heliostat, which is of great significance to the stable performance of photovoltaic power generation system.
This design of heliostat system wind-induced vibration characteristics detection system, is based on LABVIEW virtual software design test experiment. Through the independent design and development of vibration detection and control system of the overall framework, and for experimental research, the main design stated the hardware circuit design and software circuit design. The hardware platform was built by combining economy and practicability. Based on LABVIEW software of virtual instrument, the wind-induced vibration characteristics detection system of heliostat system for real-time data acquisition and monitoring was written.
The real-time data acquisition and detection control system was built by LABVIEW virtual software to meet the design requirements. Real-time control and analysis of experimental data were carried out, waveform was displayed through the display window, alarm circuit was added, and data acquisition rate could be set at the same time. The function met the requirements, and the system ran relatively stably. The software modularization of vibration detection system has laid a foundation for later development and design.
