Abstract:
SO2 and NOx are important components of
atmospheric pollutants produced by coal combustion process
and significant emissions of these gases keep deteriorating
urban air quality and cause a great threat to
soil, water and forest. The increasingly serious environmental
pollution not only resulted in significant economic
losses, but also had a great impact on human health.
Application of automated on-line monitoring system is one
of the effective ways to improve environmental monitoring
technology. Therefore, according to actual needs,
automated environmental monitoring technology is applied
to build up an environmental monitoring system with intelligence,
high precision and high reliability, which can
be used in the specific environment of daily living and
production. This study puts forward an automatic environmental
monitoring technology. With comprehensive
consideration of working environment particularity of the
environmental parameter monitoring system as well as
working characteristics of Single Chip Microcomputer
(SCM) and front-end sensor, a design scheme for environmental
parameter monitoring system with AT89C52 as
the core is put forward. With a combination of data acquisition,
analysis and processing, display and data communications,
the scheme can ensure the efficient and
stable realization of all design requirements by the system.
According to the design requirements, signal acquisition
and processing is realized, corresponding actuators
are controlled and necessary assessment is provided.
Meanwhile, all data are centralized displayed and uploaded
to upper computer.
