Civil engineering accidental state monitoring data acquisition method, storage medium, gateway and system

Abstract

The invention discloses a civil engineering accidental state monitoring data acquisition method, a storage medium, a gateway and a system, and the method comprises one or more of the following steps: determining whether an accidental state condition is satisfied based on the acquired physical performance data of civil engineering, and if the accidental state condition is satisfied, improving the acquisition frequency of the physical performance data; meanwhile, if the accidental state condition is met, dynamically covering and storing the acquired physical performance data and transmitting the data to a server in a mode that the time-frequency relation is far low and near high, otherwise, transmitting the data to the server at low frequency; in addition, if the accidental state condition is not met, intercepting the collected physical performance data in a mode that the time-frequency relation is far low and near high and serves as effective data needing to be stored. According to the method, the purposes of effectively capturing the accidental state data and not generating redundant monitoring data occupying too much storage resources are achieved, civil engineering is judged, and a scientific and direct technical means is provided for issuing of emergency plans.

Description

technical field [0001] The invention relates to data in the field of civil engineering health monitoring, in particular to a data collection method, a storage medium, a gateway and a system for occasional state monitoring of civil engineering. Background technique [0002] Civil Engineering Health Monitoring (CEHM) technology is to use the detected object response, combined with the characteristic analysis of the system, to obtain various physical performance indicators of civil engineering objects and evaluate their integrity, damage severity and location Damage location. The basic idea is to infer changes in properties of civil engineering objects by measuring their response before and after extraordinary loads, and then detect and evaluate damage, or to discover long-term degradation of object performance through continuous monitoring. [0003] CEHM technology can realize automatic and continuous monitoring and observation of engineering objects with the least manpower. ...

Problems solved by technology

[0008] In addition, the wireless sensor network in the monitoring system is usually equipped with a large number of sensor nodes (stress, temperature, deformation, acceleration, etc.), and each node is a source node that generates data, resulting in a large amount of data in the network at the same time. Storing these data at the same time will consume a lot of storage resources even if the usual data compression technology is used

Simultaneous transmission of all data will inevitably generate large network bandwidth and energy consumption, and problems such as congestion, access conflicts, and large delays will occur

In addition, with the complexity and diversification of application scenarios, the types and quantities of information generated by wireless sensor networks will increase, and a large amount of redundant and useless information will bring significant energy consumption requirements and data storage space requirements. And directly affect the utilization efficiency of monitoring data
