中文摘要:为提升杆塔状态在线综合监测的精度,设计基于卫星编队的杆塔状态在线综合监测系统。基于卫星轨道动力学方程和卫星轨道编队方式,采用卫星编队定位技术定位杆塔物理位置,根据在线综合监测装置内置的倾角传感器,实时采集杆塔倾斜角数据,计算杆塔倾斜度,并向CMA传输计算数据,判断综合倾斜度是否超出阈值,在超出阈值时及时预警,并通过GPRS网络将监测数据打包压缩传输至监控中心,实现杆塔状态在线综合监测。实验结果表明,当卫星间距为2 km时,误码率最低,且随着卫星数目的增加,误码率增长缓慢;塔架倾角最大误差仅为0.19°,监测精度高。

Design of On-line Comprehensive Monitoring System for Tower Status Based on Satellite Formation
Abstract:In order to improve the accuracy of on-line comprehensive monitoring of tower status, an on-line comprehensive monitoring system based on satellite formation is designed. Based on the dynamic equation of satellite orbit and the formation mode of satellite orbit, the physical position of the tower is located by using the satellite formation positioning technology. According to the built-in inclination sensor of the on-line integrated monitoring device, the tower inclination angle data is collected in real time to calculate the tower inclination, and the calculation data is transmitted to CMA to judge whether the comprehensive inclination exceeds the threshold, and the early warning is timely when it exceeds the threshold, Through GPRS network, the monitoring data is packaged and compressed to the monitoring center to realize the on-line comprehensive monitoring of tower status. The experimental results show that when the distance between satellites is 2 km, the bit error rate is the lowest, and with the increase of the number of satellites, the bit error rate increases slowly; The maximum error of tower inclination is only 0.19 °, The monitoring accuracy is high.
