Software Development Of The Distributeing Meteorological Monitoring Microsystem

The meteorological data acquisition system is expected to be able to acquire remote meteorological data timely, accurately and reliably to realize automation of meteorological measurement and remote meteorological measurement. At the same time, the quality of the meteorological data acquisition system need to be enhanced through software and hardware.. Because the acquisition of the meteorological data is not very high, mature and available hardware system scheme is adopted. Thus, the requirement of the acquisition is satisfied and the cost of the whole system is reduced. The hardware scheme of the meteorological data acquisition system includes a microprocessor , a preprocessing computer and a central computer. An automatic meteorological station is composed of the microprocessor, the preprocessing computer and meteorological microsensors.But different meteorological data acquisition system has different requirements of meteorological data, So the thesis focuses on the complementation of the software of the meteorological systems. The development of the system software includes the requirement analysis of the software, the design of the program flow process, coding, the test of the software, and the maintenance of the system software.Firstly, the frame of the meteorological system and the requirements of the development program of software are introduced; Secondly, two key modules of the software, communication modular and data processing modular are discussed. Thirdly, the operation flow and user interface of the software are presented. At last, some problems during the debug and the performance of the software are discussed, and some ports of the software which need to be improved are discussed.The data acquisition system can fulfill five main functions as follows:acquisition of the meteorological data such temperature, atmospheric, pressure, visibility, wind velocity and direction with high reliability.displaying, preservation and issuance of different meteorological data according to different requirements.communication between different hardwareevery automatic meteorological station can accomplish mission designated in advance.the central computer can work in automatic mode and on-duty mode. The procedure of the development of the software, the realization of the remote communication and the design of man-computer interface are useful for the design of similar system.
