Abstract
The utility model discloses a sulfur dioxide detector having an alarm function, comprising a measuring gas chamber, a light source arranged on one end of the measuring gas chamber, optical systems arranged on the two ends of the measuring gas chamber, and a single chip connected to the light source, as well as an alarm device connected to the single chip, wherein the alarm device is preferred to be a sound alarm. The sulfur dioxide detector has the alarming function and thereby is capable of giving an alarm when the content of the sulfur dioxide gas exceeds the standard, thereby reminding people to take corresponding prevention measures.
Description
Technical field
The utility model relates to the detector of the sulfur dioxide gas body burden in a kind of monitoring of environmental.
Background technology
Sulphuric dioxide is colourless gas, has penetrating odor, is one of several kinds of major pollution materials in the atmosphere.Airborne sulphuric dioxide can stimulate the respiratory tract of human body, weakens respiratory function, and causes the respiratory tract resistibility to descend, and the various inflammation of bringing out respiratory tract are detrimental to health.Thereby the content of sulfur dioxide in the monitoring of environmental is significant.Existing sulfur dioxide gas detector is of a great variety; But all these sulfur dioxide gas detectors only are the content of the sulphuric dioxide in the testing environment; If the content overproof of the sulphuric dioxide in the environment; The detector caution that can not give the alarm, thereby, do not reach real monitoring, the effect of protection.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of sulphuric dioxide detector with warning function is provided.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of sulphuric dioxide detector with warning function; Comprise and measure air chamber, the light source that places said measurement air chamber one end, the optical system of being located at said measurement air chamber two ends and the single-chip microcomputer that is connected with said light source, also comprise the warning device that is connected with said single-chip microcomputer.
As optimized choice, said warning device is a voice guard.
Said measurement air chamber comprises air intake opening and gas outlet, and said air intake opening is connected with gas to be measured, and said gas outlet is connected with aspiration pump, and said aspiration pump is connected with single-chip microcomputer; Said optical system comprises first lens combination and second lens combination that places the other end of measuring air chamber that places between light source and the measurement air chamber; Place said second lens combination spectroscope afterwards; Place said spectroscope optical filter afterwards, will change the detector of electric signal input single-chip microcomputer into through the light of optical filter.
The beneficial effect of the utility model is: have warning function, when the sulfur dioxide gas content overproof, can give the alarm, carry out corresponding precautionary measures with the prompting people.
Description of drawings
Fig. 1 is a kind of system construction drawing with sulphuric dioxide detector of warning function of the utility model.
Embodiment
Below in conjunction with accompanying drawing and practical implementation example a kind of sulphuric dioxide detector with warning function of the utility model is done further explain.
Please with reference to Fig. 1, a kind of sulphuric dioxide detector with warning function of the utility model comprises the measurement air chamber, measures air chamber and establishes air intake opening and gas outlet, and air intake opening is connected with gas to be measured, and the gas outlet is connected with aspiration pump.Light source places an end of measuring air chamber.Between light source and measurement air chamber, be provided with first lens combination, first lens combination becomes parallel beam to light source.The other end measuring air chamber is provided with second lens combination, and second lens combination is assembled parallel beam and is Ray Of Light.After second lens combination, be provided with spectroscope, the detector of establishing optical filter after the spectroscope and will changing electric signal input single-chip microcomputer into through the light of optical filter.Single-chip microcomputer also is connected with aspiration pump, light source and voice guard connects.
The principle of work of the utility model is following:
The light that light source sends is modulated into pulsed light beam by single-chip microcomputer, and this light beam forms parallel beam through first lens combination and gets into the measurement air chamber.Aspiration pump rotates during instrument work, and gas to be measured is continuously through measuring air chamber.Light beam is injected gas to be measured and is absorbed by sulphuric dioxide in measuring air chamber.Parallel beam after the absorption is assembled Ray Of Light incident spectroscope by second lens combination, after spectroscope absorbs, forms measuring beam.Measuring beam shines detector after through optical filter, and detector is changed to the electric signal of corresponding size with the light signal of measuring beam, and electric signal is sent into the concentration that demonstrates sulphuric dioxide after single-chip microcomputer is handled.When the trial of sulphuric dioxide exceeded setting value, single-chip microcomputer sent to voice guard with signal, and voice guard is given the alarm.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
