A Design And Research Of Integrated Digital Meteorograph Based On Ethernet

Meteorological instruments provide data sources for meteorological information, which is the foundation for the operation and development of the meteorological services. The achievements of meteorological technology and the information technology, especially that of computer network, provide great technique supports for meteorological information collecting, processing, distribution, ultilization and management, etc.Employing mature technology in computer domain impels information resources management of meteorological instrument equipments, through the ethernet, independent resources dispersed in each place can be interconnected to form a data network, which has become an inevitable trend for modernization of meteorology technical equipments.Meteorological equipment must have standard interfaces and protocols by which to get into the digital network, except basic observation function. Then it can be seen as a half-independent node of the meteorological independent observation and processing system that supports the independent meteorological information Intranet. Integrated digital meteorograph, as the most important meteorological instrument of meteorological observation has been widely applied in the meteorological domain. Studies are carried out in this dissertation about it based on Ethernet.A design of a kind of integrated digital meteorograph is given in this dissertation including related theory basis, technical route, key technologies, hardware and corresponding application software design. Best meteorological sensor and proper algorithem are chosen with consideration requirements in fact to improve mearsure quality; LPC2294 is chosen as the main processor to improve data processing ability and rate; module design is employed in software design to achieve better openability and transplantability, furthermore data transfer is realized based on Ethernet by which to carry management through network, and corresponding management software are developed to generate reports, trend graphs, etc.. Further meteorological analysis can be carried out based on the design in this dissertation, data processing ability and data transfer reliability can be improved greatly.
