Aimimg at the monitoring and analysis requirements of the paying off pulley during the tension process paying off construction,the monitoring system of the paying off pulley is designed.Based on sensor information intelligent fusion technology,the multi-parameter monitoring device is adopted,and the space attitude,load and other parameter sensing monitoring units are integrated to realize the three-axis attitude and angle of the paying off pulley real time acquisition and transmission of the multi-parameter data such as the spatial position and load information.Combined with the setting out construction calculation method,the spatial attitude angle calculation method of the setting out pulley is proposed.The calculation results of the change of the setting out pulley load and spatial attitude angle can be obtained through the operation state of the traction rope and conductor in different stages,and compared with the monitoring data in the system,the real-time early warning in the construction process is realized.Through the verification test in the transmission line project,the relative error between the measured data and the calculated data is relatively small,which verifies the effectiveness and accuracy of the monitoring system.The setting out pulley monitoring system can provide technical guarantee for the safety of the tension setting out construction process.
