本文根據(jù)數(shù)字農(nóng)業(yè)發(fā)展的現(xiàn)狀和需求，提出了一種針對農(nóng)業(yè)環(huán)境信息遠程監(jiān)測的系
統(tǒng)設計解決方案---以ARM CPU 為核心的硬件系統(tǒng)，在μC/OS-II 嵌入式操作系統(tǒng)的調(diào)度下實現(xiàn)信號的采集，現(xiàn)場傳感器數(shù)據(jù)通過CDMA 模塊發(fā)送致數(shù)據(jù)庫服務中心。此方案的實現(xiàn)明顯改善了系統(tǒng)的綜合性能，更能適合分散遠程條件下農(nóng)業(yè)環(huán)境監(jiān)測的需要。

Abstract: According to the development and tendency of digital agriculture, the design and solution for a monitoring system of remote and wireless agricultural environment was presented. For this solution , ARM CPU was used as the core of the hardware system , the μC/OS-II was selected as the embedded operating system, and the data from the field sensors were transmitted by CDMA module via INTERNET to the center of the data web server. The results showed the solution had greatly improved the integrated performances and made it more suitable for getting agricultural environment information distributed from remote places.
