Description
Technical field
The utility model relates to gas detecting system, especially relates to a kind of stench sensor node apparatus that utilizes and replaces the information of human olfactory, the good odor pollutant that also sensor node can be detected of reproducibility to implement to be transferred to the stench on-line monitoring system of central server or internet.
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 stench sensor node apparatus that can utilize to replace the information of human olfactory, the good odor pollutant that also sensor node can be detected of reproducibility to implement to be transferred to the stench on-line monitoring system of central server or internet.

As a kind of optimal way, described node communication module and center communication module are 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 stench 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 stench 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 is based on the sensor node of USN (in the storage and uniform network system that merges NAS and SAN under the IP agreement) and the information of odor pollutant that sensor node is detected implements to be transferred to integrated system on central server or the internet.Especially odor pollutant information is passed through the stench diffusion model, confirm the variation of stench on time, space in the visualization mode, prediction is based on the technology of the stench influence circle of meteorology, time.Therefore, compare manual in the past stench detection method, in time, have unrivaled strong point economically, can greatly improve simultaneously convenience to the stench management work of stench management area and emission source, emission problem to the high concentration stench is taked corresponding measure rapidly, and can be used as the basic document use of formulating the stench policy direction.
The utility model range of application is very wide:
A. government and commune---the stench management system as industrial zone/industrial park is used;
B. general enterprise---use as factory's stench management system;
Use as inside plants operating environment and stench management system;
Stench management system as the environmental basis facility is used;
