野外实验站观测数据远程传输方案与设计——以中国农业大学石羊河实验站为例

Remote Transmission Project and Design of Field Experiment Station Observation Data-Take Shiyanghe Experimental Station of China Agricultural University as an Example

【目的】建立数据远程传输系统可以提高信息传递效率,减少人工采集的误差及对作物的破坏。【方法】在中国农业大学石羊河实验站进行了数据远程传输的系统设计与安装,该实验站以交流电供电为主要方式,采用光纤传输和大功率WiFi通信传输为主,利用无线网桥构建局域网,作为AP进行热点覆盖,解决了传统监控中布线难的问题,其他数据传输量少的设备采用Zigbee无线电台,对站内主要设备联网,采用Campbell公司提供的LoggerNet软件(最新版4.2版本)对Campbell数据采集器保存的数据进行实时采集及远程传输,包括数据显示与下载,程序输入与导出,参数修改等。【结果】数据远程传输系统建立以后,相关信息的获取不再受到时间和地点的限制,有利于多源数据的汇总与分析,为用户提供实时动态的数据产品。【结论建立】的野外实验站的数据远程传输方案可用于国内许多偏远地区的观测站的建设。

【Objective】Improve the efficiency of information transfer,reduce the error of manual collection and damage to crops.【Method】The system design and installation of remote data transmission was carried out at the Shiyanghe Experimental Station of China Agricultural University.The experimental station was powered by alternating current.China Agricultural University Shiyanghe Experimental Station to AC power supply as the main mode,we used optical fiber transmission and high-power WiFi communication transmission based on the use of wireless bridge to build local area network,as AP hot spots to cover the traditional monitoring difficult to solve the problem,other devices with less data transmission uses Zigbee radios to network the main equipment in the station.LoggerNet software(latest version 4.2)provided by Campbell Company was used to collect and transmit the data saved by Campbell data collector in real time,including data display and Download,program input or export,parameter modification and so on.【Result】Data remote transmission system was established,the access to relevant information was no longer subject to time and place restrictions,was conducive to the collection and analysis of multi-source data to provide users with real-time dynamic data products.【Conclusion】The data remote transmission program of the field experimental stations mentioned in the article provides construction ideas and reference cases for observation stations in many remote areas in China.
