Abstract
The utility model discloses a noise warning device, which comprises a shell, and a power supply module, a photosensitive switch, a decibel instrument and a single chip microprocessor sequentially connected in series, wherein the decibel instrument is connected onto the input end of the single chip microprocessor; the output end of the single chip microprocessor is connected with a loudspeaker; the single chip microprocessor carries out feedback control on the decibel instrument via a delay start circuit; the microphone of the decibel instrument and light-sensitive elements of the photosensitive switch protrude out of the surface of the shell; the decibel instrument and the loudspeaker are both arranged inside the shell; and gate holes corresponding to the loudspeaker are also arranged on the shell. The noise warning device disclosed by the utility model can not only automatically issue a warning sound to warn people when the noise in the surrounding environment is large to keep the public place to be quiet, but also can automatically sense light brightness to start working during the daytime and stop working at night or when the light is dim, thereby achieving energy conservation and environmental protection.
Description
Technical field
The utility model relates to a kind of noise detection device, relate in particular to a kind of can be automatically according to the noise warning device of luminance brightness switch operating state.
Background technology
Usually there is automatic people to send various noises in the public arena, affects other people and normally learn, work or have a rest.The effect of pointing out with the warning poster is difficult to reach desirable requirement, needs a kind of automaticity device high, initiatively prompting badly and solves this problem.
The utility model content
The technical problems to be solved in the utility model provides a kind of noise warning device, automatically send caution sound when noise is larger in the environment around and remind people, the peace and quiet that keep the public arena, and automatically induction light brightness with switch operating state, energy-conserving and environment-protective.
To achieve these goals, technical solution adopted in the utility model is: a kind of noise warning device, comprise shell, also comprise successively power module, light activated switch, decibel instrument and the single-chip microcomputer of serial connection, described decibel instrument is connected to the input end of described single-chip microcomputer, the output terminal of single-chip microcomputer is connected with loudspeaker, and single-chip microcomputer carries out FEEDBACK CONTROL by the delayed startup circuit to the decibel instrument; The microphone of described decibel instrument and the light sensitive component of described light activated switch all protrude from described case surface, and described decibel instrument and loudspeaker all are arranged on the inside of shell, also are provided with the grid hole corresponding with described loudspeaker on the described shell.
As a kind of optimal technical scheme of the present utility model, the outside surface of described shell also is provided with relay indicating light, and described relay indicating light is controlled by described light activated switch.
As a kind of optimal technical scheme of the present utility model, described power module is attaching plug.
The beneficial effect that adopts technique scheme to produce is: the utility model automatically sends caution sound when noise is larger in the environment around and reminds people, the peace and quiet that keep the public arena, and automatically induction light brightness, enable daytime, night or light quit work in the time of dark, energy-conserving and environment-protective.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, shell 2, power module 3, light activated switch 4, decibel instrument 5, single-chip microcomputer 6, loudspeaker 7, grid hole 8, relay indicating light 9, delayed startup circuit.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing, comprise shell 1 in the structure of an embodiment of the utility model, also comprise successively power module 2, light activated switch 3, decibel instrument 4 and the single-chip microcomputer 5 of serial connection, decibel instrument 4 is connected to the input end of single-chip microcomputer 5, the output terminal of single-chip microcomputer 5 is connected with loudspeaker 6, and single-chip microcomputer 5 carries out FEEDBACK CONTROL by 9 pairs of decibel instrument of delayed startup circuit 4; The microphone of decibel instrument 4 and the light sensitive component of light activated switch 3 all protrude from shell 1 surface, decibel instrument 4 and loudspeaker 6 all are arranged on the inside of shell 1, also be provided with the grid hole corresponding with loudspeaker 6 on the shell 1, the outside surface of shell 1 also is provided with relay indicating light 8, relay indicating light 8 is subjected to light activated switch 3 controls, and power module 2 is attaching plug.
Duty is enabled in light activated switch 3 induction light brightness daytime, and relay indicating light 8 is bright simultaneously, and night or light quit work in the time of dark, and relay indicating light 8 extinguishes simultaneously, demonstrates fully the theory of energy-conserving and environment-protective; Noise loudness in decibel instrument 4 testing environments, the signal that then noise is exceeded standard when decibel value surpasses preset upper limit reaches single-chip microcomputer 5 and processes, then single-chip microcomputer 5 control loudspeakers 6 send the environment that phonetic warnings such as " quiet pleases " points out people to keep quite, meanwhile, single-chip microcomputer 5 is by delayed startup circuit 9 FEEDBACK CONTROL decibel instrument 4, make decibel instrument 4 when loudspeaker 6 is play phonetic warning, suspend noise gathering, the loudspeaker 6 rear decibel instrument 4 that quits work recovers normal conditions, thereby avoids decibel instrument 4 to gather wrong noise signal.
Foregoing description only proposes as the enforceable technical scheme of the utility model, not as the Single restriction condition to its technical scheme itself.
