Embodiment Construction

[0020] like figure 1 As shown in the super high-rise construction, different types of sensors are arranged on the corresponding measuring points. The sensor types include structural load monitoring sensors and structural real-time mechanical state sensors. The structural load monitoring sensors include wind speed and pressure sensors, temperature sensors, and seismic load sensors. Structural real-time mechanical state sensors include stress-strain sensors and acceleration sensors. And each sensor needs to have a sensor node, the function is to send the collected data to the sink node through the NB-IOT network.

[0021] The sink node receives data collected from various types of sensors and sends them to the mobile data collection base station. The transmission method is NB-IOT network.

[0022] The mobile data acquisition base station is a data gateway, and its working mechanism is that when the gateway receives the NB-IOT frame, it uses the relevant protocol to encode the...

Abstract

The invention discloses a super high-rise construction process structure health intelligent monitoring system based on NB-IOT technology and edge computing. The system comprises a sensor system, a sink node, a mobile data acquisition base station and a central server. The NB-IOT technology and the edge algorithm in the low-power wide-area Internet of Things (LPWAN) are used for collecting, transmitting, analyzing and early warning structural health monitoring data in the super high-rise construction process, and the problems that in the monitoring process, line damage is caused in the construction process, and missing is caused due to too many super high-rise monitoring data are solved. The method comprises: performing data feature engineering processing by utilizing the original triaxialdata acquired by the sensor, and selecting the triaxial data subjected to data characterization processing to perform value operation; and outputting a pre-judgment result through edge calculation according to the obtained operation value, screening characteristic data, packaging and uploading the characteristic data to the central server, and combining an output result of the edge calculation with a processing finite element analysis result of the central server to complete real-time early warning of the structure and realize integral optimal judgment.

Description

technical field [0001] The invention relates to the field of super high-rise structure construction process monitoring, in particular, an intelligent super high-rise construction process structural health monitoring system based on NB-IOT technology and edge computing. Background technique [0002] With the development of the economy, my country's super high-rise building projects continue to increase, and the design height continues to increase. The structure of the super high-rise project is relatively complex, and the mechanical characteristics of the structure during the construction process are different from those after the completion of the construction. The construction is difficult, the construction period is long, and safety accidents are prone to occur during the construction process. Structural health monitoring during super high-rise construction is very necessary, so construction process monitoring has become an important field of civil engineering research and...
