SYSTEM FOR ENVIRONMENT QUALITY SUPERVISION ON THE

INDUSTRIAL PATFORMS

The system achieves technological control

of pollution level into a zone with noxious

generating units The system assures all local environment

data acquisition and processing and

transmits them, via satellite , in the

INTERNET network


4/22

System Features:

Continuous acquisition of on-site analog and

digital values

Analog /Digital Conversion Local processing (filtering, normalization, average

values)

On schedule data transmitting over the geo-stationary satellite network ORBCOMM to a data

server

Public access via Internet

DATA ACQUISITION

The analyzer INFRARED -2 measures thelevel of the noxious (in particular CO) andis provided with current output (4-20mA)

The voltage analog input of the ST2500-C communicator measures voltage in therange 1..5 V

The A/D Conversion resolution is 10 bits Final measured values are given in mg/m3

The level of the imission noxious

(STAS 12574 compliant):

Pre-alarm value for CO: 4,2 mg/m3

Alarm value for CO : 6,0 mg/m3

TESTING THE FUNCTIONAL

MODEL

In the time period 19.08.2002 – 10. 12. 2002 the

Environment monitoring system for industrial areas was

installed in a five floor administrative building at METAV SA,

in Bucharest. The collected environmental data was published on METAV SA website. Generally, the pre-alarm

value wasn’t exceeded (see fig. 2 and fig. 3). Only in the

period 4-6.08.2002 the pre-alarm value was exceeded with

the medium value : 0,3mg/m3. Then the medium temperature

was high (about 40oC - 42o C). Also in 13.08.2002 (medium

temperature 34oC) and 23.08.2002(medium temperature

38oC ) the pre-alarm value was exceeded .

TESTING THE FUNCTIONAL

MODEL

In September (13.09.2001), while the system was running, we

made measurements with an analyzer which measured the CO

instantaneous values. The measured value was 1,25 mg/m3 in

the interval 12.45-13.00 (Bucharest time) and 0.7mg/m3

at13.20 (Bucharest time) . The average values published on the

Internet in the interval 12.00-14.00 and 14.00-16.00

(Bucharest time) was 1.45mg /m3 and respectively 1.25

mg/m3. In November (14.11.2001) while the system was

running we made measurements with the OLDHAM analyzer

between 12.00-14,00 (Bucharest time) . Between the measured

value and the average value published on the Web site was an

error of 0.10 mg/m3 (6%) . This means that the average values

published on the web site are real .

CONCLUSION

The acquired results determine us to conclude the

Environment Monitoring System is a very important tool for

industrial companies. By the mean of this system theindustrial companies can perform the control of pollution

level in their action area . Also the communication channel

via satellite has a small cost in comparison with other

communication means.
