Research & implementation of Tianxingzhou bridge health monitoring system integration

Abstract

This paper takes Tianxingzhou bridge health monitoring system for example to illustrate its integration research and implementation. Multithread technology of LabWindows/CVI which is a development environment for virtual instrument is applied in the paper. The data request, data acquisition, data processing and storage can be carried out simultaneously in multiple threads. Assigning a reasonable schedule among the threads can better ensure the real-time of the system. In this system, status information of data acquisition, processing, storage and analysis for the modules, such as meteorological, vehicle detection, pressure and expansion joint can be got reliably. And in a long term, the system runs normally, and plays an important role in ensuring the safe operation of the bridge and extending its service life.
