Railway environment vibration real-time monitoring and analyzing system

Abstract

The invention discloses a railway environment vibration real-time monitoring and analyzing system which comprises acceleration sensors, an NI9075CompactRIO terminal, an NI9234 collection module and a railway environment vibration real-time monitoring and processing system. The acceleration sensors are placed at measurement points, the acceleration sensors at the measurement points are connected into four channels of the NI9234 module through BNCs, the NI9234 module collects vibration acceleration of the four measurement points at the same time and is inserted into an NI9075 computer case, and the NI9075 computer case is connected with a PC provided with the railway environment vibration real-time monitoring and processing system through an RJ-45 Ethernet port. The railway environment vibration real-time monitoring and analyzing system has the advantages of being capable of monitoring railway environment vibration data in real time, carrying out 1/3 octave frequency spectrum and Z-vibration-level real-time analysis display, and estimating influences of railway vibrations on the surroundings.

Description

technical field [0001] The invention belongs to the technical field of railway engineering, and in particular relates to a real-time monitoring and analysis system for railway environment vibration. Background technique [0002] The impact of railway vibration on the surrounding environment has become an increasingly prominent environmental and social issue. Domestic experts have done a lot of research on railway environmental vibration, and the current environmental vibration research takes the range of 1Hz-80Hz as the scope of vibration research and evaluation. The evaluation indicators for evaluating the environmental vibration caused by train operation are mainly 1 / 3 octave frequency spectrum and Z vibration level, which are obtained by calculating and analyzing the vibration acceleration. Therefore, monitoring and analyzing the vibration acceleration caused by the train is an important measure to evaluate the vibration of the railway environment. [0003] Scholars at ...
