Design and implementation of low redundancy data acquisition for basement pressure limiting anti-floating device

以建筑物地下室限压抗浮装置监测系统为例,介绍了一种对偶发状态进行长期监测的数据处理方法,给出了动态频率选样的设计思路和实施的数据处理模型,在监测系统获得能还原偶发状态关键数据的同时,大大减少了数据传输量,节省了存储空间,实现了低冗余数据采集的设计目标。为诸如雷击、强风、地震等外荷载触发的结构响应提供了偶发状态的数据采集方法,并为类似结构健康监测提供了可借鉴的技术路线。

Based on the data acquisition system of basement pressure limiting anti-floating device,a data processing method for long-term monitoring of fortuitous circumstance was introduced.The design method of dynamic frequency sampling and the corresponding data processing model were proposed.The low redundancy data acquisition system obtained key data that could recurrence the fortuitous circumstance,meanwhile the quantity of data transmission was greatly reduced and the storage space was saved.The case provides data acquisition method of fortuitous circumstance for structural response triggered by external loads such as lightning,strong wind and earthquake,and provides technical route for similar structural health monitoring.
