Environment noise wireless real-time monitoring system based on ZigBee technology

Abstract

The invention discloses an environment noise wireless real-time monitoring system based on a ZigBee technology, mainly comprising a noise monitoring control device and more than one terminal noise monitoring device, wherein the terminal noise monitoring device and the noise monitoring control device are connected by a wireless communication mode. The environment noise wireless real-time monitoring system based on the ZigBee technology can be used for monitoring municipal environment noise, and has broad application prospect; noise intensity analysis is carried out in a dispersed mode at each terminal noise monitoring device, the treatment pressure and system communication expense of the noise monitoring control device are reduced, and the system data treatment delay and transmission delayare reduced to realize real-time noise monitoring; and a ZigBee noise monitoring network has the characteristic of self organization, and the terminal noise monitoring devices are easy to join the network, thereby greatly facilitating the extension of system capacity.

Description

technical field [0001] The invention relates to a ZigBee technology and an environmental noise monitoring system, belonging to the field of wireless communication. Background technique [0002] Environmental noise, as an important environmental factor that directly affects human survival and health, has attracted people's attention day by day. Noise has adverse effects on human health and seriously interferes with people's life, rest and sleep. Noise interference is easy to make people tired and distracted, seriously affecting production safety and work efficiency. High-intensity noise can even cause physical damage to building structures and objects. Therefore, the measurement of environmental noise is of positive significance for monitoring and controlling noise pollution and improving the living environment of human beings. [0003] With the development of wireless communication technology, various wireless communication technologies have been widely used in the measur...

AI Technical Summary

Problems solved by technology

[0005] At present, ZigBee technology has not been used in the wireless real-time monitoring system of environmental noise, and the existing environmental noise monitoring system usually has the disadvantages of poor real-time monitoring and inability to cope with sudden noise pollution, and cannot guarantee the continuous and uninterrupted work of the system, especially when Disadvantages such as the need for complex network configuration when adding or moving the terminal noise monitoring device

When faced with the increasingly common demand for large-area multi-point real-time all-weather noise measurement, traditional environmental measurement systems have been unable to efficiently and successfully complete the task
