The Data Transfer Of Automatic Weather Station And Application Investigation Based On GPRS Wireless Communication

With the rapidly development of wireless communication technologies, a growing number of businesses being used to resolve all kinds of practice needs by using wireless communication to resolve communication problem where are in remote and unmanned and the inconvenient paving communication cable area. The wireless communication way is rapidly developed in recent years. GPRS occupy a piece of wireless communications sky by its unique advantages. This paper chose the GPRS wireless communication way as the way for solving non-watching of meteorological data transmission.The design of this paper is in accordance with the obtaining meteorology elements information process. Analyzing and explaining whole process from the collecting of the meteorological data to generating of customer demand of meteorological information. The system has four tiers. The first tier is the data collection. Meteorological sensors are mainly used to obtain various meteorological elements. Then the collector changed pressure , electric current and impulse signals to analog or digital signals. The paper will begin from the research principle of sensors. It analyses the principle that the meteorology sensors get meteorological factors. Then the paper researched the designing principle of the collector. The second tier is data transfer. It researched that GPRS wireless communications way transmits meteorological data, analyses the characteristics and advantages of GPRS wireless communications and signal transmission method in the process of meteorological data transmission. The third tier is the data receiver. Explained the reception of send data of GPRS in center server and storage in documentation forms. The fourth tier is the data processing. It deal with original acquisition of meteorological data, get the various meteorological products of user demand. Moreover the paper analyses and expounds the whole design idea of non-watching Automatic Meteorological Station System.This paper combined with the actual weather conditions from the practical work, used the existing meteorological sensors to collect weather elements. Through the design of the data acquisition system, using GPRS wireless transmission methods to send meteorological data...
