Description

Technical Field

[0001] The present application relates to the technical field of smart construction sites, and in particular to an intelligent video monitoring system for foundation pit construction based on the Internet of Things. Background Art

[0002] Foundation pit monitoring is an important part of foundation pit construction. It refers to various observations and analyses of changes in foundation pit rock and soil properties, support structure displacement, and surrounding environmental conditions during foundation pit excavation and underground engineering construction. The monitoring results are fed back in a timely manner to predict the deformation and stable state that will result from further construction, and to determine the extent of the impact of the construction on the surrounding environment based on the prediction.

[0003] Supervision during foundation pit construction is often carried out manually. Technical personnel need to carry relevant image acquisition equipment to the site to conduct on-site data collection and image collection, and import the data into the early warning platform for modeling and analysis. The early warning platform detects the images collected by the technical personnel and issues early warnings when the foundation pit deformation is too large or the water level rises too fast.

[0004] However, since data collection on the foundation pit site needs to be done manually, the manual collection method cannot achieve all-weather monitoring, and the measurement time interval is large, it is easy for safety hazards to be undiscovered in time, resulting in untimely warnings. If the measurement interval is shortened, the labor consumption of technical personnel will be large, and there is a certain risk of technical personnel frequently entering and exiting the foundation pit, so this needs to be improved.
