Sensor node used for monitoring underground substation construction displacement

Abstract

The invention relates to a sensor node used for detecting underground substation construction displacement. The sensor node comprises a sensor component, a power supply component and a power cord, wherein the sensor component is connected with the power supply component through the power cord; the sensor component comprises a first housing, a sensor mounted in the first housing, a processor, a power supply management module, a wireless transmission module, and an aerial wire mounted on the first housing; the processor is connected with the sensor and the wireless transmission module respectively; the power supply management module is connected with the sensor, the processor and the wireless transmission module respectively; the wireless transmission module is connected with the aerial wire; the power supply component comprises a second housing, and a battery pack mounted in the second housing; the battery pack is connected with the power supply management module through the power cord. Compared with the prior art, the invention has the advantages that the sensor node is good in air tightness, high in waterproof grade, convenient for operation and data acquisition, low in construction cost, and the like.

Description

technical field [0001] The invention relates to an underground substation construction displacement monitoring device, in particular to a sensor node used for underground substation construction displacement monitoring. Background technique [0002] With the needs of urbanization construction, projects such as subways and high-rise buildings are being vigorously constructed, and most of the construction of these projects requires excavation of foundation pits in densely populated urban areas. During the excavation of deep foundation pits, the pressure on the walls of the pits will cause large deformations in the pit, which will cause hidden dangers to the safety of the foundation pit project and the surrounding buildings. Particularly important. In foundation pit safety monitoring, it is necessary to monitor the foundation pit and the surrounding environment during the excavation and construction of the foundation pit, to warn and prevent the occurrence of excessive displac...

AI Technical Summary

Problems solved by technology

A little carelessness will not only endanger the safety of the foundation pit itself, but also affect the surrounding buildings, roads and various underground facilities, causing serious social impact and economic losses.

Inadequate monitoring of foundation pit engineering often leads to major safety accidents
