The Design Of The Atmospheric Environment Monitoring System Based On ARM

In recent years, environmental problems become important problems in people’slives, haze, water pollution seriously affect people’s health. Environmental issues arenot only related to the social hot topic but also are serious problem that people securetheir own survival. Wanting to know the real-time environment, the severity ofenvironmental pollution, environmental conditions predicted for the future, we mustdevelop a safe and stable, real-time, accurate environmental monitoring systems.The system is based on ARM9embedded environmental monitoring systems,the ARM9development board is introduced in detail, the design is the main circuitboard. Then it introduces the temperature and humidity sensor and the dust particlesensor. The hardware system of this topic, in the core ARM9platform built on U-Boot and Linux2.6kernel. Subjects completed the process, mainly to solve the nextU-Boot porting drivers, Linux kernel cutting and transplantation, YAFFS2production file system, Linux under the driver and application design. After theentire system software design and development, including two digital sensor driverpreparation and socket network communication, allowing the system to achieve theenvironmental temperature, humidity, light intensity, and data collection of dustparticles.The atmospheric environment monitoring equipment by sensing equipment real-time state data acquisition environment, temperature and humidity of theenvironment, real-time status of dust particles into specific data, making it moreintuitive while observing environmental issues. Its high-performance applicationprocessor, suitable operating systems and digitized sensor,ensure the accuracy,theefficiency and the intelligence of the data system.The system can be widely used inhospitals, factories and other places of environmental data collection.
