用于监测森林环境因子的原野服务器的设计与应用

Design and Application of Wilderness Server Using Monitoring Forest Environment Factors

森林环境因子的监测对森林生态环境的研究和对森林火灾的预防有重要的作用。该原野服务器的特点在于构建基于arm和linux操作系统的微系统,该服务器能够用于采集与森林环境相关的因子参数,能够连接数字视频接收器和无线局域网模块,用无线以太网连接原野服务器和办公室客户端,解决了森林中无法施工布线、视频图像和控制信号采集传输难等疑难问题。该系统已成功应用在伊春市朗乡林业局的防火和监控工程上,视频和数据传输的有效距离达15 km以上,并通过现场的反复测试验证。

The monitoring of forest environment factor plays a key role in research of forest ecological environment and prevention of forest fire. The wilderness server was consisted of arm-epu and the linux os. The environment factor data was sampled by this server and the technology of digital video and wireless LAN was used. The server and indoor client were connected by wireless LAN . This technology solved some difficult problems such as wiring from the forest to town, and the transmission of video image data and control signal. This system has been successfully used in fire protection and monitoring project of Langxiang Town forestry bureau in Yichun City. The validated transferred distance was over 15 km, and was verified by the repeated tests .
