| 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，通过安装在杆塔上的监测移动站获取杆塔状态，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，该系统各项功能均可满足应用需求；当卫星间距为2km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。 |

| 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. The status of the tower is obtained through the monitoring mobile station installed on the tower. According to the built-in inclination sensor of the online 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 the comprehensive inclination The monitoring data are packaged and compressed to the monitoring center through GPRS network to realize the online comprehensive monitoring of tower status. The experimental results show that all functions of the system can meet the application requirements; when the satellite spacing is 2km, 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 ° and the monitoring accuracy is high. |
