Development of Remote Waste Gas Monitor System
In order to effectively supervise factory chimney waste gas circumstance, a kind of remote waste gas monitor system is designed, with the ARM as its core controller, collects the chimney pollutant indexes consisting of exhaust particulate, sulfur oxides, carbon oxides as well as nitrogen oxides through different gas sensors, and takes advantage of Global Positioning System(GPS) to obtain the chimney position accurately, after that, the information it collects is transmitted to the center control computer via GSM or the complete public switched telephone network. Moreover, in order to provide the environment protection departments convenience in supervising factories making little environmental pollution, the system also uses Global System for Mobile Communications wireless transmission way in which it alarms when the collected data exceeds the national standards. All the real-time data is not only transmitted by the public switched telephone network or GSM system to the core computer, but also stored into SD memory card through SPI interface. Practical run shows that the system is well realized the function of GPS positioning, remote data transmission, xceeding-standard-alarming, and data storage,and the precision of system is no higher than 2.5 percent.
