Research On Meteorological Data Acquisition And Processing System

With the social rapidly development, the global meteorological environmental is constantly changing, and meteorological environmental issues increasingly became the focus of attention. The demands for weather information services have undergone profound changed. At the same time, because of its excellent characteristics of high timeliness, high reliability, low power consumption and also can be cut, etc. Embedded system has been the rapid development and wide application in the field of consumer electronics, communications, automotive, defense, aerospace, industrial control, instrumentation and office automation, and the market is very broad. So, embedded system will be an inevitable trend to be widely used in ground meteorological observations intelligent system. This paper combined with the application development of the hottest Android embedded operating system, researched and devised embedded meteorological data acquisition and processing system, to provide a reference for the use of embedded technology to develop meteorological data acquisition and processing system.In this paper, we used S5PV210microprocessor with the embedded Cortex A8architecture and high performance, high speed, cost-effective and low power consumption for the core of the hardware system, and established the overall framework of the system hardware platform. And accomplished the chip selection for the meteorological data acquisition module, main control module and data transmission interface module, devised the connectivity solutions of the circuit of the various parts of the module.This paper is due to the features and the architecture of Android operating system to realize the transplant of Android to S5PV210. And established the overall framework of the part of the system software, and give the programming of the initialization of meteorological data acquisition and processing system and four meteorological elements of data acquisition and processing tasks. Compiled the LCD、UART and ADC interface driver functions. At last, designed the user interface based on Android embedded application development process, to achieve the effect of real-time display of meteorological element data.This system makes full use of the characteristics advantage of the S5PV210ARM microprocessor, and exerts the Android system’s advantages of openness, portability and the development of fast, to provide a practical solution for intelligent meteorological data acquisition and processing system.
