Synchronous mode and alignment mode are the focus of this system. Synchronous mode Because the weight of the large-capacity fan is as high as 1041t, it has a great impact on the lower positioning system during the overall lifting process. In order to reduce the impact acceleration, the system designed four sets of hydraulic cylinders (two in each group), evenly distributed on the lower seating system. During the landing of the fan, the parameters of the hydraulic cylinder must be carried out, including stroke and pressure uniformity.
The monitoring interface of the synchronous hydraulic cylinder group, the centering mode in the overall lifting process of the large-capacity offshore wind turbine, the centering of the upper and lower flanges is mainly by capturing the center of the upper and lower flange holes, and then pushing the upper hanger through the hydraulic cylinder Move on the X and Y axes so that the center coordinates of the upper and lower flange holes are the same, and finally the centering of the upper and lower flange holes is achieved. Therefore, in the monitoring process, the system obtains the coordinates of the center of the upper and lower flange holes, and displays the coordinate values ​​in the monitoring interface, and simulates two circles in the interface to represent the upper flange hole and the lower flange hole respectively. In this way, not only can the center coordinates of the upper and lower flange holes be clearly seen, but also the process of alignment can be visually observed.
The data transmission of the remote monitoring system uses the MR-900E high-speed EV-DO3G module, and the download and uplink peak rates are 3.1MB/s and 1.8MB/s, respectively, ensuring the effectiveness and reliability of data transmission. The design of the remote monitoring interface is more user-friendly, the operation is simple and convenient, the real-time performance is good, and it is close to the requirements of customers. In addition, the system uses modular design of components and is compatible with PCs or other software. In today's rapid development of the information age, engineering applications are increasingly demanding remote monitoring data transmission capabilities. Therefore, remote monitoring using 3G networks with wide bandwidth is bound to become a trend.
