Abstract
The utility model relates to gas detection equipment, and discloses an odor detector based on an electronic nose technology, comprising a detector main board which is fixed in an outer shell, a communication module, an electronic nose sensor, a micro gas pump, a power supply, a liquid crystal displayer and a control panel which are arranged on the outer surface of the outer shell, and a vent pipe which is arranged on the outer shell; the electronic nose sensor, the communication module, the micro gas pump, the liquid crystal displayer and the control panel are electrically connected onto the detector main board; and the vent pipe is connected with the outside environment and the electronic nose sensor through the micro gas pump. The odor detector based on the electronic nose technology has the advantages that mixed gas with a plurality of components can be accurately monitored, a human olfactory system can be replaced, and the reproductivity is good.
Description
Technical field
The utility model relates to gas detection equipment, especially relates to a kind ofly replacing human olfactory, the good stench detector based on Electronic Nose Technology of reproducibility.
Background technology
Stench is meant unpleasant stink.At present, known odorant has kind more than 4,000, and common has: can send the hydrogen sulfide gas of rotten-egg odour, can send the sulfur alcohol compound of mashed onion flavor, mashed leek smell, unpleasant pitch steam also has some Benzazole compounds that can stink.Many foul gas are all harmful, and toxicity such as pitch steam, sulfuretted hydrogen, ethamine, acryl aldehyde are all very big.After odorant enters atmosphere,, also can allow the people be sick in the stomach even concentration is very low.Because odor pollution is principal character with the psychological impact, it is unhappy that extremely low concentration just can make the people produce, and this makes it measure very difficulty.Add, the odor pollution source mostly is the uncontrollable discharge source, and diffusion way is difficult to catch, and estimates difficulty, also do not have a kind of generally acknowledged stench evaluation method so far in the world, environmental monitoring field, the whole world does not also have environmental monitoring technology ripe, that can replace human olfactory.
The reason that produces harmful gas is varied, and composition is very complicated, and is accordingly can compellent monitoring instrument not selective, for a long time, single component gas can only be monitored in China and even countries in the world, can not monitor mixed gas, for example stench as multiple composition.The foundation of administrative penalty is to use " hearing smelly teacher " (distinguishing smelly teacher) system.There are the following problems to distinguish smelly teacher's system detection: 1, be passive detection.After stench takes place, have the resident to complain, distinguish that smelly teacher receives the notice of environmental administration, go to the resident to complain the ground point sampling, per hour once sampling is taken a sample four times altogether, adopts four bottles of samples of foot, often is sampling all night.The laboratory is taken back in sampling, and the environmental protection supervisor organizes six to distinguish that smelly teacher compares and distinguish smelly, distinguishes the foundation of smelly result as administrative penalty; 2, the body ﹠ mind of distinguishing smelly teacher is very big to smelly feel influence, and accuracy often is under suspicion; 3, stench is very big to the body ﹠ mind harm of distinguishing smelly teacher.
Summary of the invention
In order to overcome above-mentioned shortcoming, the utility model purpose is to provide a kind of mixed gas that can accurately monitor multiple composition, can replaces human olfactory, the good stench detector based on Electronic Nose Technology of reproducibility.
The utility model is realized by following technical measures, a kind of stench detector based on Electronic Nose Technology, comprise fixing detector mainboard, communication module, Electronic Nose sensor, micro air pump and power supply in the enclosure, be arranged on the LCD and the control panel of outer surface of outer cover, and be arranged on the snorkel on the shell; Described Electronic Nose sensor, communication module, micro air pump, LCD and control panel all are connected electrically on the detector mainboard; Described snorkel connects extraneous and Electronic Nose sensor by micro air pump.
As a kind of optimal way, described communication module is any one or a few the combination in RS485 communication module, RS232 communication module, Zigbee communication module, GSM communication module, the CDMA communication module.
As a kind of optimal way, described Electronic Nose sensor comprises the sensor array that a plurality of metal oxide sensors, electrochemical sensor and photoion sensor are formed.
As a kind of optimal way, described Electronic Nose sensor comprises that also 1 meteorological Wucan counts sensor.
As a kind of optimal way, described power supply is solar cell, city's plug, rechargeable battery or dry cell.
As a kind of optimal way, also be electrically connected the temperature regulator that is provided with in the enclosure on the described detector mainboard.
As a kind of optimal way, also be electrically connected audible alarm unit, light alarming device or the combination of the two that is arranged on the shell on the described detector mainboard.
The utility model carries out the stench monitoring in order to replace artificial sense, and the utility model can be used for the environment in areas such as chemical industrial park, refuse landfill and plant or the stench of floss hole is monitored in real time.Electronic Nose sensor in the utility model is as the detection inductive material of smell, use be the semi-conductor type smell sensor that has adopted metal-oxide semiconductor (MOS).By carrying out hundreds of degrees centigrade heating, the principle of responsive variation can take place along with the absorption and the surface reaction of its surperficial scent molecule in semi-conductive resistance value.Therefore, can carry out highly sensitive detection to the smell of trace.In addition, be not subjected to the influence of environment temperature and humidity etc., reproducibility is good.The utility model maneuverability is good, can use at the scene and good repeatability is arranged, and can be as sense of smell smell do not become and adapt to or custom.In addition, can in time Monitoring Data be sent to Surveillance center by communication module.When exceeding standard, the smell of monitoring place can also remind the staff by warning device by real-time on-site.
