Design of High Precision Building Warning and Monitoring System Based on BDS

针对北斗高精度楼宇变形监测特点,提出了扩展动态非线性Kalman滤波算法进行双差、三差解算,并采用基于双差模型的北斗高精度静态基线解算方法,研制开发了基于北斗的变形监测软件。为降低系统成本,采用一机多天线设计高精度接收机,相对于传统人工建筑位移监测系统,该智能预警监测系统具有全天候、高精度、自动化程度高等优点。

According to the characteristics of Beidou high-precision building deformation monitoring, an extended dynamic nonlinear Kalman flter algorithm is proposed to solve the two-difference and three-difference problems. The deformation monitoring software based on BDS is developed by using the high precision static baseline calculation method based on double difference model. In order to reduce the system cost, a one-machine multi-antenna high-precision receiver is designed. compared with the traditional artifcial building displacement monitoring system, the intelligent early warning monitoring system has the advantages of all - weather, high precision, high degree of automation and so on.
