精准农业分布式数据采集与空间决策分析系统的设计

Design of a distributed data acquisition and spatial decision making system for precision agriculture

田间数据的实时采集、传输与处理是实施精准农业的关键环节。长期以来,困扰该环节的一个技术瓶颈是客户端实时数据采集与服务器端联动式决策的一体化处理。本文利用A rcIM S的技术框架,利用A rcXM L语言,开发了适用于精准农业分布式数据采集、可独立运行、能实现空间决策分析的技术系统。系统由数据采集、数据处理、信息分析与智能决策4个模块组成。本文结合该系统在莱西市高科技农业示范园区的应用实例,揭示了这一系统的逻辑设计、物理实现、技术特色及主要功能。该系统的逻辑设计为精准农业园区高效采集、传输、处理信息和数据提供了一套可行的技术框架。

One of the key technologies for implementing precision agriculture is to collect and process timely spatial-temporal information from various sources that affect crop production in the field. That means the system must integrate the Client＇s data acquisition and Server＇s spatial analysis functions, and transfer data rapidly via Internet, by which different decision makers can realize dynamic communication mutually. Using ArclMS technology framework and ArcXML language, a technology system was designed. The system has four functional modules, including data acquisition, data handling, information analysis, and intellectualized decision making modules. Based on its application in Laixi High-tech Agricultural Demonstration Zone, the system logical design, physical implementation, technical characteristics, and its main functions were described and analyzed. The results show that the system can provide an integrated set of technologies for efficient data acquisition, handling, transferring and decision making, which has good adaptability specifically for precision agriculture.
