Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific examples, but the scope of application of the present invention is not limited thereto.

[0032] combine figure 1 , the transmission of vibration and noise generated by subway operation in the surrounding environment will affect the work and quality of life of the surrounding people. Generally, conventional environmental tests only consider a single vibration or noise factor. This invention adopts a group of wireless sensor nodes to be deployed in the target area, which can simultaneously acquire environmental vibration and noise data, and output the weighted vibration level of the environment through internal processing of the nodes. and A sound level, and save it on the PC side. The obtained results can be used as a reference for the management department in order to carry out targeted control and treatment of environmental vibration and noise pollution ...

Abstract

A method for joint testing of subway environmental vibration and noise, by arranging a group of wireless nodes in a selected measurement area around the subway to obtain data on the vibration and noise of the surrounding environment of the subway, and each node passes the BNC interface on-site Equipped with vibration acceleration and noise or sound level sensors, the collected acceleration and sound pressure data are converted into the weighted vibration level and sound level in the environmental assessment through the embedded DSP chip of the node; all wireless nodes are in a wireless sensor network, through the internal The clock completes time synchronization. After a test is completed, all test data and processing results are wirelessly transmitted to the base station connected to a group of wireless nodes and finally stored on the PC. The wireless nodes use Zigbee-based wireless nodes. The invention is easy to install and flexible to use, and can simultaneously collect the vibration and noise data of the subway environment in real time.

Description

technical field [0001] The invention relates to the field of vibration and noise environment monitoring of urban rail transit, and proposes a method and system for joint testing of subway environment vibration and noise. Background technique [0002] With the development of my country's social economy, the rapid development of the subway transportation system, while bringing convenience, the problems of environmental vibration and noise caused by its operation have become increasingly prominent, which has brought certain troubles to the daily life and work of the surrounding people, and even affected to human health. The analysis and evaluation of environmental vibration and noise caused by urban subway operation has become a research hotspot in recent years. Traditional evaluation methods only use a single vibration or noise as an evaluation reference, and cannot comprehensively and accurately analyze and evaluate the engineering and noise caused by subway operation. Enviro...
