Study And Design Of Environment Parameters Monitoring System Based On SCM

Nowadays environmental pollution has become one of the main factors of thenational development and people healthy. In recent years, most regions of thecountry for a wide range of fog, the concentration of PM2.5, the management ofenvironmental pollution has come to the point where it is urgent. In theenvironmental monitoring research in China has been developing quickly, but thereare also many problems. Due to a late start, environmental monitoring technologyin China is not accurate and timely reflects the status of the all dangerousenvironment parameters monitoring in living and production area in the inner ring,at the same time by using artificial control also caused great waste of manpowerand material resources. Therefore, according to the actual needs, the developmentof environmental monitoring technology is an urgent need to build an application inthe specific environment of people’s living and production collected works aboutintelligent environment monitoring system, high precision, and high reliability.This paper has taken a full account of environmental parameter monitoringsystem, as well as the specificity of the working environment and single-chipfeatures the front-end probe. It put forward a kind of dust concentration monitoringprogram based on AT89C52. On the one hand, environmental parameter sensor isused for environmental parameter sampling and output the frequency signal whichis adapted to environmental parameter monitoring system and then into the singlechip to do calculations, on the other hand, the signal from MCU is sent into the hostcomputer through the communication network. Then VB programming is used formany groups of data storage, visual display and resulting report. Finally the designof environmental parameter monitoring system is completed.The scheme integrates the sampling, analysis and processing of the data,control, display, and alarm and data communications in one system, which canensure the efficiency and stability. It satisfies the designing requirements of theprogram. It can sample and process data, output alarm signal as well as controlrelevant executive part of the system. Meanwhile it is able to transmit all the data tothe computer. Thesis from the hardware, software and PC carried out on threeaspects. The main thesis is as follows to do the job.Hardware aspects: put forward a kind of excellent performance, the cost isrelatively low environmental parameters monitoring system of circuit design;Design the processor AT89C52and various environmental parameters of the sensor,relay and RS232interface circuit; For the RS232wireless pass through modulemakes a detailed introduction.Software: the acquisition and processing of frequency signal is completed, serial communications, such as programming, data processing procedures forDebugging and programming flow chart is given.PC: design and developed the operating system based on VB6.0. This paperDesigned man-machine interface from both the practical and beautiful aspect; thebackground system database was set up.
