Design Of Dust Concentration Monitoring And Implementation

With the rapid economic development, People are damaging the environment is becoming more and more serious. Nowadays, the environment pollution is the most popular human concern. Although modern society, people’s material life conditions have never been improved, But life is gradually environmental quality is low. Air is necessary to human existence; its itself is a mix of many invisible pollution and dust. With the modernization of the city development, leading to the air pollution and dust particles more serious. Make people survival environment more and more to worsen. Especially the industrial development zone, environmental pollution problem is especially worrying. In order to better tomorrow and future, we should always stay hold our survival environment condition, And then carry on the improvement and protection. Therefore, the atmosphere dust pollution became we pay special attention to one of the pollution of the environment.Since the reform and opening in China, the industrial developments is rapid, economic and thus gain the rapid growth, but growing energy consumption and motor vehicles increased China’s urban atmospheric environment burden, urban air pollution as one of the main environmental problems is rapidly released. For our country city in the main pollution sources for various industrial production process of atmospheric pollution and residents coal burning pollution. In addition, in recent years the number of private cars rising sharply and municipal construction, etc, has brought serious environmental problems.Through the above problem can see, design a good dust concentration meter as people’s living environment physiological guidance doctor, is a very necessary things. It is perhaps before is a fantasy, but for today’s science and technology so developed social speaking, monitoring system to the research and development of the field has been deeply, making a good monitor is a special industry, it is in on the basis of predecessors, this topic research is complying with launched.This system is the most important purpose is to the air dust concentration, particle degree, etc. Various kinds of pollution concentration monitoring, thus accurate brace hold air quality. thus can according to its pollution level to take the corresponding effective measures to improve air and improve the quality of people living environment, protect the environment. maintenance and preservation of our home, realize the harmonious development of the socialist society.This system is a kind of based on ARM concentration dust monitoring system. System based on S3C2410as hardware platform, with embedded Linux system for development environment, and design corresponding driver. At the same time also introduce high-performance Embedded GUI system development kit-Qt/Embedded, On the basis of the development of dust concentration monitoring system and the graphical user interface.Linux is a UNIX-like operating system, it is a kind of UNIX, and it controls the whole system of basic service core program. Linux with UNIX system program interface with the mode of operation, but also inherited the characteristics of the UNIX stable efficient. Linux system has text editing interface and graphic user interface. Its features include:many users, multitasking, multiple platform, programmable SHELL, provide source code, simulation terminals, support for multiple file system and powerful function of the network, etc.The system applied above technology mainly realizes the following functions:data collection, data processing, display data, reset data. Therefore, this system is also divided into the four function modules. Data collection module that is when the system running work, sensor module continuous acquisition air dust concentration of data, and the data to the CPU. Processing data module that is DSM501sensor module to the collected data to the CPU later, CPU according to application processing the data obtained, namely to30s for a cycle, At the end of a cycle, according to the low level rate calculated the current of air dust concentration and particle number. Display data module using Qt/Embedded graphics library, write graphical user interface, the interface dynamic display detected dust concentration and corresponding particle number. Reset data module in does not require the system mon dust concentration, the user interface of numerical zero.This system has many advantages. Through the above system design, The dust concentration monitor effectively realize the continuous detection existence of inflammable and explosive combustible gas mixture environment floating dust concentration, Has the fast and accurate measurement, high sensitivity, in situ display, remote signal transmission, stable performance, can be preset K value functions and characteristics, And with all sorts of monitoring system supporting the use.ARM of the dust concentration monitor system in power on running good, stable, the used in various occasions are working good stability, basic conform to the market demand. But the system need to code optimization, need to continue to upgrade and promotion.The system for air quality accurate monitoring will give people more accurate an effective information, The popularization and application of environmental protection to the society will bring very benefit. Also for people’s life bring more enjoy.
