Design Of Remote Data Management System Based-on ARM9

With the rapid development of semiconductor technology, the microprocessor, the core chip of RTU, is more powerful. Data processing capacity of RTU has been greatly improved, many of the more complex algorithms and communication protocols can be achieved. Using RTU in the oil field can control the on-site real-time data, and thus can acquire data and publish data on remote, therefore it is significant to increase productivity and protect workers. With the embedded Linux systems and remote Web client technology, the on-site data is collectioned and uploaded to the web client via the network.Firstly, the embedded database SQLite and Web server ware analyzed, and the overall architecture of the system was designed, including hardware platform, software platform, boa module of web server, and SQLite database module.Secondly, in order to apply the ODBC and JDBC interfaces that can access by heterogeneous database in ARM embedded platform, through the test program for the three interfaces as API, ODBC, JDBC, the application transplant proved correct.It realizes on-site data collection and storage,accessing remote device data to the Internet, and also achieve management of the remote data.Finally, the porting of Boa server and SQLite databases were completed under the Embedded System.Implements the data collection and storage, user can access to remote devices on the internet data, realize the remote data management.
