Abstract

The utility model relates to a monitoring device, in particular to a city noise monitoring device. The city noise monitoring device comprises a sound pickup module, a gain amplifying module, a CPU (central processing unit) controller, an alarming module, a GSM (global system for mobile communication) transceiving module, wherein an output signal of the sound pickup module is sent to the CPU controller by the gain amplifying module; and the output of the CPU controller is connected with the alarming module and the GSM transceiving module. When the sound pickup module of the city noise monitoring device detects that noise in an environment surpasses a set value, a singlechip sends an alarming message to a real estate department or an environmental protection department and makes an alarm on site to remind people of reducing noises so as to keep a good environment.

Description

A kind of city noise monitoring device

Technical field

The utility model relates to a kind of monitoring device, particularly be a kind of city noise monitoring device.

Background technology

Along with the continuous development of people's life, factory and city noise are often perplexing people's work and life, have caused great inconvenience to people.

The utility model content

The purpose of this utility model is providing a kind of city noise monitoring device.

The technical scheme that the utility model adopted is such: a kind of city noise monitoring device, comprise pickup module, gain amplification module, cpu controller, alarm module and GSM transceiver module, the output signal of described pickup module sends to cpu controller through the gain amplification module, and described cpu controller output connects alarm module and GSM transceiver module.

Described pickup module adopts microphone to pick up the surrounding environment sound source.

Described gain amplification module adopts the UA741 high gain operational amplifier.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: when the pickup module of this device detects neighbourhood noise above setting value, send warning message by single-chip microcomputer to property or environmental administration, chimes of doom is sent at the scene simultaneously, reminds people reduces the noise content that produces, so that keep good environment.

Description of drawings

Fig. 1 is a frame structure synoptic diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment

Further specify the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, a kind of city noise monitoring device, comprise pickup module 1, gain amplification module 11, cpu controller 2, alarm module 21 and GSM transceiver module 22, the output signal of described pickup module 1 sends to cpu controller 2 through gain amplification module 11, and described cpu controller 2 outputs connect alarm module 21 and GSM transceiver module 22.

As shown in Figure 2, microphone MIC is used to pick up the surrounding environment sound source, the source of sound that picks up as microphone MIC is coupled through capacitor C 1, after being input to UA741 high gain operational amplifier IC2 amplification, the 6th pin output signal by UA741 high gain operational amplifier IC2 is coupled through capacitor C 2, after triode Q1 detection, be input to the 32nd pin of single-chip microcomputer IC1 again, the volume that reads as single-chip microcomputer IC1 surpasses the inner setting value, after inner single-chip microcomputer IC1 routine processes, the 6th pin output low level by single-chip microcomputer IC1, promote loudspeaker BD and send alarm sound, illustrate that surrounding environment has exceeded the interface scope, and by the 1st of single-chip microcomputer IC1,2,3,12 pin and GSM transceiver module IC2 connect to form the data transmission telecommunication circuit, GSM transceiver module IC2 input is connected with pull-up resistor R5-R8, its output connects antenna TX, sends the operator on duty mobile phone of SMS alarm information to appointment when sent data command driving GSM transceiver module IC2 by single-chip microcomputer IC1, shows the phenomenon that the surveillance area exists noise to exceed standard.

More than show and described ultimate principle of the present utility model and principal character and advantage thereof; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the explanation just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
