Design Of Fan Blade Pose Monitoring System

With the aggravation of the world energy crisis and the increasingly serious environmental pollution wind power generation as a clean new energy has been widely used in the world.The fan blade is the core part of the whole generator set,which is related to the amount of capturing wind energy.Therefore,the development trend of large fan blades is very obvious,and at the same time,it causes difficulties for the transportation of fan blades in rugged mountain roads.Once there is a slide and rollover,the loss is huge.In addition,the dispatching situation of the fan blade conveyer also needs to be monitored in real time.In view of the above requirements,this paper designed and developed a monitoring and management system for the position and posture of fan blades in the process of transportation.Based on relevant functional requirements,the system is mainly divided into two parts: vehicle terminal and monitoring platform.The on-board terminal takes STM32 processor as the core,combines MPU6050 sensor,GPS positioning module and EC200 S communication module to realize GPS data acquisition and analysis,attitude angle calculation,data packaging and transmission,remote server communication and other functions.For the attitude angle solution,this paper adopts the quaternion attitude solution algorithm based on EKF,combined with the actual data and modeling,completed the simulation verification in Matlab,and finally programmed into the processor attitude solution program.Also on the Flash memory management program design,the use of flash cache and update the pose data,to avoid the weak signal caused by disconnection with the server resulting in data missing.The monitoring platform was developed by using SSM framework technology,and the database was constructed and developed by combining My SQL database and Navicat for My SQL visual database operation environment.Finally,the whole monitoring platform was deployed on the cloud server.Firstly,the functional requirements of the monitoring platform are analyzed and the overall functional structure,logical structure and technical architecture are designed.Secondly,the database design,the establishment of the E-R relationship between the data table and the storage of the relevant information of the data table.Then realize the requirements of each function module of the monitoring platform,including user login,real-time monitoring,track reproduction,background management,information display,attitude alarm and other functions.In addition,the trajectory data is preprocessed,and the trajectory optimization algorithm is used to filter and obtain the drift points in GPS data,and the trajectory is reproduced on the monitoring platform for verification.Finally,each functional module of the whole monitoring system is debugged and verified to ensure that the monitoring system meets the relevant functional requirements.The functional tests were carried out in the school to realize real-time location positioning,trajectory reproduction,trajectory optimization and attitude display and other related functions.
