Problems solved by technology

However, when used in construction environments such as building foundation pits, it is often damaged
For example, the excavator unintentionally cuts the buried cable
In addition, in many cases in actual measurement, the displacement of the supporting wall of the foundation pit is enough to cause the bending deformation of the inclinometer tube, so that the sensor cannot enter the inclinometer tube, resulting in the failure of the monitoring point

Abstract

A wireless signal transmission deep displacement monitoring device comprises an inclinometer tube and a plurality of displacement monitors, each displacement monitor comprises a columnar shell, and a triaxial accelerometer module, a data processing module, a wireless narrowband ad hoc network module and a power module are arranged in each columnar shell. The triaxial accelerometer module is connected with the signal input end of the data processing module, and the data processing module is connected with the wireless narrowband ad hoc network module; the two ends of the columnar shell are provided with an air connection plug and an air connection socket respectively. The power supply modules of every two adjacent displacement monitors are electrically connected through an air connection plug and an air connection socket. And the power supply module in the displacement monitor at the uppermost end is connected with an external power supply through a power supply cable. The defects in the prior art are overcome, wireless data transmission of the deep displacement monitoring equipment in the construction site is achieved through the communication means of the wireless narrowband ad hoc network, cable laying is not needed, and the risk that cables are damaged is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of deep displacement monitoring, in particular to a deep displacement monitoring device and error testing method for wireless signal transmission. Background technique [0002] In the current deep displacement monitoring, the following method is mainly used for measurement: firstly, a measuring inclined pipe is preset, which runs through from the surface of the soil to the bottom of the soil. The inclinometer tube has internal grooves for orientation. When measuring, align the guide wheel of the deep displacement monitoring equipment with the groove, slowly lower the control equipment cable to the bottom, and then slowly pull it up. During this period, the equipment measurement data is transmitted to the equipment controller through the cable, and then the memory card inside the controller is pulled out, and the data is copied to the personal computer for data processing and analysis. [0003] All similar ...
