手持式移动终端平台在农业信息采集与监控领域得到广泛应用。为了降低通信成本和提高通信可靠性,本文基于Internet的C/S架构,设计了移动终端平台与数据采集汇聚节点的多径通信系统,并实现了温室监控数据的远近程通信。远程通信时,移动终端平台通过3G或4G电信网络登录到Internet网络,与汇聚节点服务器实现数据通信;近程通信时,移动终端平台通过局域网WiFi的AP模式与汇聚节点直接通信。温室环境参数监测测试结果表明,移动终端能够可靠的的获取温室汇聚节点的数据,并根据网络连接状态和WiFi信号强弱实现远近程两种通信模式自由切换。
手持式移動終耑平檯在農業信息採集與鑑控領域得到廣汎應用。為瞭降低通信成本和提高通信可靠性,本文基于Internet的C/S架構,設計瞭移動終耑平檯與數據採集彙聚節點的多徑通信繫統,併實現瞭溫室鑑控數據的遠近程通信。遠程通信時,移動終耑平檯通過3G或4G電信網絡登錄到Internet網絡,與彙聚節點服務器實現數據通信;近程通信時,移動終耑平檯通過跼域網WiFi的AP模式與彙聚節點直接通信。溫室環境參數鑑測測試結果錶明,移動終耑能夠可靠的的穫取溫室彙聚節點的數據,併根據網絡連接狀態和WiFi信號彊弱實現遠近程兩種通信模式自由切換。

Handheld mobile terminal platform has been widely used in the field of agricultural information col-lection and monitoring. In order to reduce communication costs and improve the communication reliability, in this paper, a multipath communication system, which has achieved remote communication and short-range com-munication, has been designed between mobile terminal platform and data acquisition sink node based on C/S architecture of Internet. In the case of remote communication, mobile terminal logs on to the Internet platform to communicate with sink node by 3G or 4G network; While under short-range communication, mobile terminal communicates with data acquisition sink node by LAN WiFi-AP mode. The test results of Greenhouse environ-ment parameters monitoring show that mobile terminal is not only able to obtain reliable data from greenhouse sink node, but also achieve the free switch between remote communication mode and short-range communication mode depending on the network connection status and WiFi signal strength.
