Description
Technical field
The utility model relates to a kind of air monitering instrument, is meant a kind of volatile organic compounds monitor of (volatile organic compounds is called for short VOCs) of monitoring in atmosphere especially.
Background technology
VOCs is meant at normal temperatures, the various organic compounds that boiling point is 50 ℃-260 ℃, VOCs is by its chemical constitution, can be further divided into: alkanes, aromatic hydrocarbons, ester class, aldehydes and other etc., what identified at present has a kind more than 300, and modal have benzene,toluene,xylene, styrene, triclene, methenyl choloride, trichloroethanes, diisocyanate (TDI), two isocyanide toluene esters etc.VOCs extensively is present in the air of indoor and outdoor, is easy to cause acute poisoning during excessive concentration, and dead drunk liquor-saturated shape headache, dizziness can appear, cough, feels sick, vomits or be in the lighter; Hepatotoxicity even very fast stupor can appear in weight person, and what have also has a life danger.Therefore, must set up simple and reliable VOCs sampling monitoring work.
Monitoring method at present commonly used is that various sampling thiefs are set, and utilizes method such as vapor-phase chromatography that the air sample that collects is analyzed again, thereby obtains airborne VOCs value, takes corresponding measure according to monitoring result again.The major defect of this method is: one, the property handled is relatively poor in real time, when monitoring VOCs when changing, takes measures according to monitoring result again, can not in time handle, and responds slower.Two, sampling and monitoring device needs manual inspection and execute-in-place, and human cost is higher, and handling simultaneously can not be timely.Three, data can not record queries, can not communication so that exchanges data.
Summary of the invention
The purpose of this utility model be to provide a kind of the air sample that collects is carried out timely Treatment Analysis after, change accessible signal into, again after the processing according to central processing unit, make respective reaction such as warning, and real time record VOCs value, be convenient to query history numerical value, also, realize the telecommunication and the processing of Monitoring Data by communication interface is set.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of volatile organic contaminant monitor, include sampling and analyzing device, wind transducer, air velocity transducer, temperature sensor, power module, signal input module, memory module, clock module, Keysheet module, central processing unit, communication module, relay output module and LCD MODULE, it is characterized in that: described power module links to each other with sampling and analyzing device, wind transducer, air velocity transducer, temperature sensor and central processing unit; Described sampling and analyzing device, wind transducer, air velocity transducer and temperature sensor link to each other with signal input module; Memory module, clock module, Keysheet module, central processing unit, communication module, relay output module and LCD MODULE link to each other with central processing unit.
As further specifying, described sampling and analyzing device includes initiatively sampling thief and chromatograph, and the chromatograph front end links to each other with the active sampling thief, and the chromatograph rear end links to each other with signal input module.
As further specifying, described communication module adopts the RS232 data-interface.
Compared with prior art, the utility model utilization is sampling thief initiatively, gather air sample, to handle in the air sample input chromatograph that collect again, be connected to signal input module after the processing, the chromatogram information processing that the chromatograph analysis is obtained becomes the data-signal that can supply the central processing unit analyzing and processing, simultaneously, utilize wind direction, wind speed and the temperature signal of wind transducer, air velocity transducer, this air sample of temperature sensor monitors, and pass to the signal input module processing, be linked into the central processing unit analyzing and processing again.Clock module produces real-time clock signal, for various data provide clock signal.Memory module store various kinds of data information is convenient to record and inquiry.Keysheet module is realized the setting of various parameters and the processing such as download of data by various external commands.LCD MODULE shows various real-time sampling data and historical data etc.Communication module sampling RS232 agreement realizes data communication, is convenient to the remote download data.After central processing unit is analyzed sampled signal, if when reaching the value of setting, by instruction relay output module, processing modes such as realization Realtime Alerts.After the utility model carries out timely Treatment Analysis with the air sample that collects, change accessible signal into, again after the processing according to central processing unit, make respective reaction such as warning, and real time record VOCs value, be convenient to query history numerical value, also, realize the telecommunication and the processing of Monitoring Data by communication interface is set.Simple in structure, easy to use.
