Description
Technical field
The utility model relates to a kind of intellectual broadcast vibration-type dynamic noise watch-dog, for the examination and controlling to life, perform region environmental noise situation, in order to take in time safeguard procedures and reduce the noise source noise, reduce the impact that peripheral noise causes human body, guarantee health.
Background technology
Along with the process of urban industry, and the development construction in city, factory is more and more, and Vehicle's quantity continues to rise, and just in our living environment, has produced numerous noise sources thereupon.Live in for a long time in noise pollution, make the people be difficult to have a rest and sleep, affect human central nervous system, cardiovascular system and eyesight is produced to certain impact, even affect the growth of fetus in parent, birth may cause neurobehavioral abnormal later.
At present; domestic deep not enough with the civilian noise detector research of protection hearing for noise monitoring; there is the excessive or simple drawback of function of volume in civilian noise measuring equipment in the market; generally only has the light warning function; for the handicapped individual with there being vision disorder; it is very inconvenient to use, and causes obtaining good monitoring and taking necessary safeguard procedures living environment noise situation.
The utility model content
Technical problem to be solved in the utility model is overcome deficiency of the prior art and a kind of intellectual broadcast vibration-type dynamic noise watch-dog with various feedback modes such as photoelectric display, vibrations, voice broadcasts is provided.
The technical scheme in the invention for solving the above technical problem is: this intellectual broadcast vibration-type dynamic noise watch-dog, comprise rechargeable battery, display screen, sound collection unit, the Signal Pretreatment unit, signal conversion unit, single-chip microcomputer, model selection button and light warning unit, it is characterized in that: also be provided with shaking device and loudspeaker, described sound collection unit is connected with the Signal Pretreatment unit, the Signal Pretreatment unit is connected with signal conversion unit, signal conversion unit is connected with single-chip microcomputer, the model selection button is connected with single-chip microcomputer, single-chip microcomputer respectively with display screen, the light warning unit, shaking device is connected with loudspeaker, rechargeable battery respectively with display screen, sound collection unit, the Signal Pretreatment unit, signal conversion unit, single-chip microcomputer, the light warning unit, shaking device, loudspeaker connects.
Sound collection unit described in the utility model is electret microphone.
Signal conversion unit described in the utility model is modulus conversion chip PCF8591.
Light warning described in the utility model unit comprises green warning lamp, yellow warning lamp and red warning lamp.
Model selection button described in the utility model comprises outdoor mode button, sleep pattern button and daily life mode button.
The utility model compared with prior art has the following advantages:
1, by adopting electret microphone as the neighbourhood noise collection system, gather without distortion neighbourhood noise, and carry out amplification and impedance transformation to a certain degree.
2, by Signal Pretreatment cell isolation earphone and functional circuit, extract the maximum voltage value in sound signal by peak-detector circuit, as sampled signal.
3,, by above circuit, the voice signal of collecting is converted to simulating signal, but, because simulating signal is disturbed greatlyr, adopts modulus conversion chip PCF8591 to be converted into digital signal.
4, utilize the noise limit numerical value of single-chip microcomputer and predefined sleep pattern, daily life pattern, outdoor pattern to compare respectively, thereby can go out normally noise analysis, early warning, three kinds of effects of warning, and show by the warning lamp of different colours.
5, on man-machine communication and display alarm mode, on the basis of light warning, the automatic voice reminding and the vibration reminding mode that also do not have have in the market been increased, make the people not need the noise situations of the equipment of seeing around just knowing at present, be applicable to older or health is handicapped, the defective colony of eyesight.
