Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention will be further described:

[0018] Such as figure 1 As shown, this distributed urban environmental noise real-time automatic monitoring system is composed of a monitoring center and multiple monitoring nodes. Each monitoring node is connected to the monitoring center through the Internet. The node computers 3 are formed in cooperation, and the node computers 3 of each monitoring node are connected to the central computer 1 of the monitoring center through the Internet 2, and transmit the preprocessed noise data to the central computer 1 of the monitoring center, and the central computer 1 of the monitoring center completes the noise data analysis and display. The present invention relies on the computer, the Internet network and the LabVIEW development platform, integrates virtual instrument technology and computer network technology, and implants the noise monitoring terminal into the computer of t...

Abstract

The invention relates to a distributed urban environment noise real-time automatic monitoring system. The distributed urban environment noise real-time automatic monitoring system consists of a monitoring center and a plurality of monitoring nodes in a coordination mode. Each monitoring node is connected with the monitoring center through the Internet. Preprocessed noise data is transmitted to the monitoring center and is analyzed and displayed by the monitoring center. Node computers receive noise signals acquired by sound pressure transducers through sound cards. Node data management modules, LabVIEW node ends, NAS (Network Attached Storage) server management modules and node communication modules are all arranged in the corresponding node computers. The monitoring center is provided with a center computer. A noise data analysis module, a center data management module, a LabVIEW server, an urban noise GIS (Geographic Information System) display module and a center communication module are arranged in the center computer. According to the invention, the urban noise condition is displayed by a map unique visual effect, a visual, rapid and convenient noise monitoring interface can be provided, the cost is low, and the cost performance is high.

Description

[0001] 1. Technical field: [0002] The invention relates to an environmental noise monitoring system, in particular to a distributed urban environmental noise real-time automatic monitoring system based on virtual instrument technology. 2. Background technology: [0003] With the development of modern city construction and urban traffic, urban environmental noise pollution has become an important environmental problem faced by large cities all over the world. Noise has become the fourth largest environmental hazard after water pollution, air pollution and solid waste pollution ] . Urban noise pollution has seriously affected people's normal work, study and rest. Non-stationary noise has a stronger impact on people than steady-state noise. Unsteady-state noise interference caused by vehicles is very common in cities in our country. Studies have shown that high-intensity unsteady noise can induce various diseases, reduce work efficiency, cause production accidents, and ma...
