Problems solved by technology

[0003] Some bridge vibration data acquisition systems use wireless transmission to reduce wiring work, but these systems fail to take data acquisition synchronization measures in the wireless data acquisition system. There are not many correlations between parameters. This asynchronous data collection method lacks the ability to judge the safety of the overall structure. These abnormal data will affect the credibility of the monitoring results.

Abstract

The invention discloses a wireless synchronous sampling method and a wireless synchronous sampling system for vibrating data. The method comprises the following steps of: 1, a preparation step: clock homologous treatment, namely uniformly distributing clock signals output from a crystal oscillator to each independent data sampling channel; and synchronization time service, namely synchronously calibrating a real-time clock of each acquirer to calibrate the real-time clocks of different acquirers to the same time; 2, transmitting a data acquisition command; and 3, starting data synchronous acquisition. The wireless synchronous sampling method and the wireless synchronous sampling system can realize extremely high wireless synchronization accuracy.

Description

technical field [0001] The invention relates to a vibration data wireless synchronous sampling method and a sampling system. Background technique [0002] Most of the existing bridge vibration data collection involves heavy wiring work, which requires testers to frequently travel to and from the construction site. The labor intensity is high, data collection and transmission are inconvenient, and the degree of automation of information management is low, which makes it difficult to meet the requirements of modern information construction. Therefore, it is necessary to develop a new type of distributed remote wireless monitoring system to reduce the work intensity of engineers, improve the accuracy and reliability of data collection, and realize the intelligent and informational management of temperature and stress data. [0003] Some bridge vibration data acquisition systems use wireless transmission to reduce wiring work, but these systems fail to take data acquisition sync...
