Description
Technical field
The present invention relates to noise monitoring, and in particular to a kind of monitor of preventing and treating city noise pollution.
Background technology
Now with the development of social economy, increasing people has automobile, and the worry brought therewith is exactly to make an uproar
Sound, and noise can bring certain injury to our psychology and body.First, it can disturb the rest of living area people and sleep
Sleep, its let us is difficult to fall asleep, and then influence our the live and work situations of second day, in the course of time, our meetings will be made
Have a sleepless night, the symptom such as fatigue, and then reduce our operating efficiency.Secondly, he can also damage our sense of hearing, because people
It is prolonged by strong function of noise, hearing occurs as soon as weak, and then causes the organic damage of hearing organ, finally
Make our Hearing, influence our studying and living.Finally, it is also the most important, noise also can be to us
Physiology is impacted, and then the harm to our healthy generation necessarily.Noise level indicator present in prior art is more
For hand-held, noise monitoring is carried out for specific environment or place, but in city, the blowing a whistle of vehicle, square dance
Music, has become the noise source that can not ignore in city, and hand-held noise level monitor has not been suitable in present city
Actual conditions.
The content of the invention
The present invention is in order to solve the above problems, it is therefore intended that provide a kind of monitor for preventing and treating city noise pollution, can
It is arranged on the long-term monitoring for needing the place monitored to carry out noise.
The present invention is achieved through the following technical solutions：
A kind of monitor for preventing and treating city noise pollution, including control system, fan housing, acquisition channel, packaging ball, installation
Post, display, the packaging ball are arranged on installation top end；In a tubular form, one end of the acquisition channel is set the acquisition channel
Fan housing is put, the other end is connected on packaging ball；The display is arranged on packaging ball surface；The control system includes connecting successively
The condenser microphone that connects, preamplifier, the first attenuator, the first amplifier, spectrum overlapping network, the second attenuator,
Two amplifiers and virtual value indicating meter, the virtual value indicating meter are connected with display；The condenser microphone is set
In fan housing.
In the prior art, hand-held noise level indicator is portable, and such instrument is only applicable to need detection a certain
Just take out and use when site surrounding noise, this can only be directed to specific service condition, still, in city, noise pollution
It is increasingly severe, be to the injury of human body it is invisible, therefore, set in city necessary Noise Acquisition point be it is critically important,
Traditional hand-held noise level monitor is can not to meet such use.
The present invention forms the profile of noise-monitoring equipment using packaging ball, acquisition channel, fan housing, is adopted by condenser microphone
Collect the noise in environment, the voice signal of collection is transformed into electric signal by condenser microphone, and electric signal also has more nothing
With signal, therefore by electric signal by preamplifier, the first attenuator, the first amplifier, spectrum overlapping network, the second decay
The a series of processing such as device, the second amplifier so that initial electric signal is converted into optical signal, i.e., carried out straight by display
Display is seen, or is shown by valid value indicating meter.
Further, the connection between acquisition channel and packaging ball is connected by back-off locking device；The back-off
Locking device includes acquisition channel shell, locking post, casing, and the acquisition channel shell is socketed on the outside of acquisition channel；Institute
State acquisition channel shell cylindrical, wall thickness is uneven, there is through hole in barrel, the locking post is arranged on described
In through hole；The bottom of the locking post is connected with locking-blade by tumbler；The shell is set on packaging ball surface,
The acquisition channel shell is connected on packaging ball by being socketed in casing.
Locking post can be slided up and down in through-holes, and the stable state of locking-blade has two kinds, and the first is locking
During post upward sliding, locking-blade in through-holes, and is that on same straight line, second is that locking post is downward with locking post
During slip, locking-blade leaves through hole, and locking-blade can be under the driving of tumbler, locking-blade and the place of locking post
Straight line is vertical.When acquisition channel is connected with the casing on packaging ball, locking-blade is exactly above-mentioned second of stable state, when
When acquisition channel is separated with packaging ball, locking-blade is exactly the first above-mentioned stable state.
Further, condenser microphone is identical with the number of fan housing, and the number of the condenser microphone and fan housing is extremely
It is few 5.Multiple condenser microphones and fan housing are set, noise from all directions can be detected, this is according to sonic propagation of making an uproar
What the particularity of mode was determined.
The present invention compared with prior art, has the following advantages and advantages：The present invention is logical by packaging ball, collection
Road, fan housing, control system formation noise-monitoring equipment, can carry out whether long term monitoring noise surpasses in any one place in city
Mark, fully achieves the irrealizable function of hand-held noise level monitor in the prior art.
