Abstract

The invention discloses a movable type intelligent noise continuous acquisition system for a transformer substation. The system comprises an acoustic measurement module, a video monitoring module, a measurement control module and a measurement data analysis module; the acoustic measurement module is used for acquiring noise time domain data through an acoustic testing device; the video monitoringmodule is used for recording corresponding noise equipment in real time during noise signal measurement through a video monitoring device; the measurement control module is used for controlling a mobile robot to walk according to routes and time so as to complete the continuous noise measurement of the transformer substation, wherein the routes and time are set according to the distribution conditions of the equipment of the transformer substation; the measurement data analysis module is used for extracting characteristic quantities corresponding to various kinds of information of the equipment in the transformer substation from the acoustic data of all measuring points and corresponding videos, generating a test data report and a noise sound source intensity display image according to thecharacteristic quantities, and drawing a transformer substation sound field distribution cloud diagram.

Description

technical field [0001] The invention relates to noise control technology, in particular to a mobile intelligent noise continuous acquisition system for substations. Background technique [0002] As the main source of noise pollution in the urban environment, substations are causing more and more frequent complaints about the radiation noise of substations. The revision of new environmental protection regulations forces the State Grid to pay more attention to the control effect of substation noise. For substation radiation noise exceeding the standard, the national environmental protection law enforcement department will also A noise tax will be levied. At present, a large part of substations have not achieved the expected effect after taking noise control and treatment measures, and the noise of substations still exceeds the standard. The reason is that the existing substation environmental noise test methods have insufficient understanding of the law of substation radiated...

Problems solved by technology

At present, a large part of substations have not achieved the expected effect after implementing noise control and treatment measures, and the noise of substations still exceeds the standard.

The reason is that the existing substation environmental noise test methods have insufficient understanding of the law of substation radiated noise, so that the formulation of noise control plans and the development of noise control projects make the actual noise control effect not as good as expected

[0003] In the process of realizing the present invention, the inventor found that the existing noise measurement technology has at least the following problems: (1) the acoustic test points before treatment can only select a limited number of points, and it is often difficult to cover the space that needs to be treated. (2) The test time is affected by the operating conditions and environmental conditions. The selection of the test time is usually arranged according to the time schedule of the project implementation, and little attention is paid to the operating conditions of the substation. In fact, the sound pressure distribution in the substation field is greatly affected by factors such as power load, seasonal weather, and other random sound sources around; (3) the judgment of the transmission path of the noise is not accurate, and the noise of the substation In the treatment, noise control is usually carried out by taking certain noise control measures on the main transmission path of noise transmission, and the judgment of the transmission path is also based on the measurement of limited points in the field. This kind of local limited point test and evaluation method is very It is easy to miss the main transmission path, resulting in the imperfection of the noise control plan, the lack of control measures, etc., so that after the final control project is completed, the control effect is not obvious.
