随着精准林业的提出,林业数字化、自动化已经成为林业发展的必然趋势。为了解决森林调查中因人为因素而导致的记录偏差问题,本文介绍一种基于PDA,并将GPS、蓝牙、声控等技术进行综合集成的森林资源连续清查样地调查应用系统的设计和实现,并对其系统结构、工作原理、硬件构成、软件设计等进行论述。该系统的开发和实现把野外调绘和数据采集融为一体,将会改变传统的野外调查方式,实现数据采集自动化,并将大大提高外业和内业的工作效率。
With the introduction of precision forestry, forestry digitalization and automation have become the inevitable trend of forestry development. In order to solve the problem of record deviation caused by human factors in forest surveys, this paper introduces a design and implementation of a survey application system for continuous inventory of forest resources based on PDA, integrating GPS, Bluetooth, voice control and other technologies. Its system structure, working principle, hardware structure, software design and so on are discussed. The development and implementation of this system, which integrates field mapping and data collection, will change the traditional field survey methods and automate data collection and will greatly improve the efficiency of field and interior work.
