Abstract

The invention discloses an environmental noise monitoring device capable of distinguishing the noise source direction, and relates to the technical field of environmental monitoring devices.The environmental noise monitoring device comprises a movable base, the top of the movable base is detachably connected with a supporting stand column, the bottom of the movable base is provided with movable universal wheels, and the top of the supporting stand column is provided with a height adjusting mechanism; a multi-directional noise monitoring mechanism is arranged on the outer wall of the supporting stand column. Noise is collected through a sound collection cylinder, transmitted into an inner cavity of a sound insulation rotating disc through a sound passing groove and monitored by a decibel detector body, a stepping motor is controlled to work, an adjusting gear can be driven to rotate, and the rotating inner gear ring synchronously drives the sound insulation rotating disc to rotate on the inner wall of a multi-directional monitoring box; and then different sound collection cylinders are switched to carry out sound collection work, that is, the function of carrying out noise monitoring on different directions is realized, and supervisors finally compare the noise received by the sound collection cylinders at different positions, so that the position of a noise source can be deduced.

Description

technical field [0001] The invention relates to a noise monitoring device, relates to the technical field of environmental monitoring devices, in particular to an environmental noise monitoring device capable of identifying the direction of noise sources. Background technique [0002] Noise is a kind of sound that causes people's irritability or is too loud and endangers human health. Noise pollution mainly comes from transportation, vehicle whistle, industrial noise, construction, social noise, such as concert halls, tweeters, morning markets and people's noise. Talking loudly, etc., there are restrictions on noise in many places in the city. Why better control of noise requires supervision departments to use noise monitoring devices for monitoring. There are following problems at prior art: [0003] 1. The existing noise monitoring device does not have the function of identifying the direction of the noise source, and can only monitor the decibel level of the noise, which...
