Device and method for monitoring axial force of steel pipe support of foundation pit based on microwave radar
The invention discloses a device and method for monitoring the axial force of a steel pipe support of a foundation pit based on a microwave radar. The method comprises the steps of transmitting a microwave signal to the steel pipe support, receiving an echo signal reflected by the steel pipe support, and converting the echo signal into a steel pipe support micro-motion time-history signal; and after the micro-motion time-history signal of the steel pipe support of a measurement unit is separated through an underdetermined time-history signal blind source separation algorithm fusing EMD and time-frequency analysis, identifying the time-varying axial force of the steel pipe support of the foundation pit by applying the EMD algorithm. In the device, the signal output end of microwave radar equipment is connected with the signal input end of a data acquisition module; the data acquisition module is connected with a data processing module through a wireless remote transmission module; and the signal output end of the data processing module is connected with the signal input end of a display module. The non-contact measurement method is high in measurement precision, long in operating distance, capable of working stably in various complex weathers and relatively low in cost.
本发明公开了基于微波雷达对基坑钢管支撑轴力监测的装置及方法，方法包括通过向钢管支撑发射微波信号并接收钢管支撑反射的回波信号，并将回波信号换算为钢管支撑微动时程信号；经融合EMD和时频分析的欠定时程信号盲源分离算法分离测量单元钢管支撑微动时程信号后，应用EMD算法识别基坑钢管支撑的时变轴力；装置中，微波雷达设备的信号输出端与数据采集模块的信号输入端连接；数据采集模块通过无线远程传输模块与数据处理模块连接；数据处理模块的信号输出端与显示模块的信号输入端连接。本申请一种非接触式测量方法，该方法测量精度高，作用距离远，能在各种复杂天气下稳定工作，成本较低。
