Abstract

The invention belongs to the field of monitoring data processing in the construction process of civil engineering, and provides a method for automatic identification and processing of construction monitoring abnormal collection data. Acceleration, etc., sequentially carry out data collection of time series data, data preprocessing of time series data, identification and deletion of burr points in time series data, and restoration of the data system, and smooth processing to make the data collected by monitoring more accurate and 1. Be truthful and objective. Through the included angle, several consecutive data acquisition values ​​in the local time range are determined to deviate significantly from the data development trend trajectory. After eliminating such data, the original glitch monitoring value is replaced with the newly calculated interpolation result, realizing the identification of glitch data. , Eliminate and smooth, improve the accuracy of data monitoring.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a data processing method for monitoring the construction process of civil engineering and health monitoring in the operation stage. Background technique [0002] At present, information technology and Internet of Things technology have been widely used in the field of construction engineering, using information monitoring technology to obtain real-time performance state parameters of structures and equipment (temperature, stress, internal force, displacement, inclination, acceleration, sound, etc.) To ensure the safety of the structure in the construction process and operation process has become an important means to improve the level of construction engineering information management. [0003] Long construction period and complex and harsh construction environment are the characteristics of construction projects. During the construction process, the str...
