Airport aircraft noise monitoring device based on Internet-of-Things framework

Abstract

The invention discloses an airport aircraft noise monitoring device based on an Internet-of-Things framework. The airport aircraft noise monitoring device comprises a power module, a signal conditioning module, a digital processing module, a wireless transmission module and a system control module, wherein the power module comprises a solar charging unit and a lithium battery which is electrically connected with the solar charging unit; the signal conditioning module is used for collecting noise signals and conducting pre-filtering, amplification, anti-aliasing filtering and analog-to-digital conversion on the noise signals; the digital processing module is used for receiving digital signals produced by the signal conditioning module and obtaining the sound pressure level of noise through the digital signals in a calculated mode; the wireless transmission module is used for achieving wireless data communication between the digital processing module and the system control module; the system control module is used for achieving management of the power module and management of the working state of the digital processing module. The airport aircraft noise monitoring device has the advantages of transmitting data conveniently, saving energy and being environmentally friendly and high in reliability.

Description

technical field [0001] The invention belongs to the field of airport noise monitoring, in particular to an airport aviation noise monitoring device based on the Internet of Things architecture. Background technique [0002] In order to meet the requirements of economic globalization, people imagine that if RFID technology, WSN technology, GPS technology, digital earth technology and the Internet are combined from the perspective of information circulation, the coverage of the Internet can be expanded from "people" to "things". . Therefore, information about logistics can be collected and obtained through RFID technology, WSN technology and GPS technology, and then the logistics information worldwide can be quickly and accurately identified and tracked with the help of the Internet. This technology is the Internet of Things technology. IoT technology has been widely used in many fields. The reason why the Internet of Things has such a wide market is mainly because it can ef...

Problems solved by technology

[0004] At present, the basic technical solution adopted by the traditional airport noise monitoring device is: set up several noise collection devices around the airport, and then use the data line to transmit the collected noise information to the remote control and monitoring center; through practice, it is found that: the traditional The airport noise monitoring device has the following defects: 1. Communication lines need to be erected during the communication process, so the installation and implementation process is more complicated; 2. The traditional airport noise monitoring device uses batteries for power supply or wires for power supply, and the former needs to replace the battery , the latter needs to lay wires, so it is extremely inconvenient to use
