[Abstract]:Forest resources are the material basis of forestry production and forestry sustainable development. Mastering the basic situation of forest resources provides an effective basis for the scientific management of forest resources. The development of embedded technology, communication technology and GIS provides a new model for data collection. In order to realize paperless and automatic data collection of forest resources, and improve the efficiency of field and internal industry, In this paper, the research of embedded forest resource information collection system based on OMAP is carried out. On the basis of introducing the background and significance of the research, this paper points out the problems existing in the research at home and abroad, and analyzes the requirements of the system. Based on the application of embedded GIS technology, 3G wireless communication technology and GPS technology, the overall system structure is established, and the system user login module, attribute data acquisition module, data storage and query module are divided into three parts: user login module, attribute data acquisition module, data storage and query module. The map operation module includes GPS positioning and navigation module, temperature and humidity acquisition module and data transmission module. The OMAP3530 with elastic structure is selected as the core, and the temperature and humidity module, GPS module and 3G wireless communication module are used as the hardware development platform of the system. On the QT / embedded platform, the upper application interface is designed and developed, Linux system and application program are transplanted successfully, and soft keyboard is provided. The system has basic GIS functions, such as map enlargement, reduction and location marking; using GPS technology to realize real-time positioning, navigation and longitude and latitude display functions; at the same time, it can save the collected small class data and temperature and humidity data. Using 3G module to access the Internet to achieve data upload and download. The forest farm of Lianyungang Xinpu District, a representative forest area of Jiangsu Province, is selected as an application example to verify the feasibility of the theory, method and technology of the system. The embedded forest resource information collection system based on OMAP3530 combines the fast speed dual-core hardware OMAP3530 with the cross-platform QT / embedded 4.5.3 by using embedded technology. The efficient configuration of software and hardware greatly improves the speed of system development, data acquisition and processing. The system extends the traditional mode to wireless network to ensure the real-time performance of the data, and the low power performance prolongs the system lifetime. This research provides technical support for the development of embedded technology in forest resource information collection system.
