PGtec FDSA is a new generation of online monitoring and diagnosis system based on NI CompactRIO. It has the high reliability and high performance of real-time operating system and the openness of Linux. Wide operating range of outdoor temperature (-40~70℃), through the time sensitive network (TSN), to achieve accurate synchronization of equipment. Various types of acquisition modules can be flexibly combined to complete dynamic and static data acquisition and long-term monitoring of various physical quantities such as stress, acceleration, speed, temperature, cable force, wind speed and direction. It can form a large-scale distributed test system with thousands of channels to monitor the health of large bridge structures 24 hours a day. When the bridge structure appears accident precursor or accident, it can give alarm in time, and provide reliable data support for understanding the accident phenomenon and analyzing the cause of the accident and the structural damage caused.
