1引言

与快速发展的一系列高技术如信息技术，生物技术和工程技术相比，“精确林业”在90年代初引入，现在正变得越来越重要。精准林业是在林业生产过程中，利用高新技术例如视觉传感器，卫星定位等检测和分析工具来获取有关工作的质量，数量和时间的即时数据，通过分析环境因素的影响，采取技术上可行，经济上有效的控制措施，以实现利益最大化和最小的环境危害[1]。

当前，精准林业的发展已经滞后与智能农业的发展。这是由于在林业生产中周期较长，干扰较多，变化更多和更复杂的条件因素造成的[2]。这些因素使得采集和传输——一个精准林业的重要组成部分，环境因素在树的生长过程中变得非常困难。因此，一个低投入、低能量、低消耗、高产出、高智能、高信息和高防护的林业生态环境监测系统应该被发展。现在，一项新技术的出现，无线传感器网络，提供了一个合适的技术手段来实现这一目标。

Abstract –In order to conveniently access information of forestry, a new technology, wireless sensor network is introduced in precision forestry applications. A forestry information monitoring system based on wireless sensor network technology is proposed, which can sample temperature, soil moisture, light intensity, nitrogen concentration and other environmental factors. The networks of sensor nodes are managed by a central node which collects and transmits data to remote host computer through GPRS. The system design methodology based on ZigBee chip 2430 is presented and the 

corresponding system hardware architecture and software flow are given. This system effectively makes it easy to collect and transmit data of environmental factors in forestry product and posses high practical values.

I. INTRODUCTION 

With the rapid development of a series of high technologies such as information technology, biotechnology and engineering technology, the concept “Precision Forestry” introduced in early 90s is becoming increasingly important. The word, precision forestry is a forestry production process in which high technologies such as visual sensors, satellite positioning and other high-tech sensing and analytical tools are used to obtain the immediate data about work quality, quantity and timing, and by analyzing environmental factors affect the growing of forestry, technically feasible and economically effective control measures are taken to achieve maximum benefits and minimum environmental hazards [1]. 

Currently, the development of precision forestry has lagged behind the development of precision agriculture. It is due to some features such as longer cycle, more......
