【摘要】：智能農業(yè)是現代計算機技術、網絡通信技術和傳感器技術相結合的產物。用戶可通過智能農業(yè)系統(tǒng)平臺，借助無線通信網絡對遠端的農作物進行智能化調控。感知適配網關作為智能農業(yè)系統(tǒng)中不可或缺的一部分，為傳感數據的中繼轉發(fā)提供了途徑。本文所設計的第二代感知適配網關是在原有基礎上對系統(tǒng)的升級，研究的重點在于對系統(tǒng)的優(yōu)先級傳輸和并發(fā)性做了性能優(yōu)化，提出了一種動態(tài)優(yōu)先級傳輸調度模型和基于IOCP的Socket通信機制。經過優(yōu)化后的感知適配網關系統(tǒng)可滿足大并發(fā)量的數據傳輸，適應了未來農業(yè)發(fā)展的需求。除此之外，本文對感知適配網關的功能做了升級并且針對其在云平臺的部署做了研究。主要研究工作如下： 1、在總結了智能農業(yè)在國內外研究現狀和發(fā)展背景的基礎上，分析了研制新一代感知適配網關的必要性及所涉及到的技術難點。 2、文章針對構建系統(tǒng)所涉及的相關核心技術進行深入研究，首先研究了網絡通信技術，對Socket編程、Windows套接字及同步異步I/O做了詳細闡述，為后來的系統(tǒng)性能優(yōu)化提供了扎實的理論基礎；其次研究了云平臺相關技術，包括云平臺的定義、特點、應用和體系架構，為后面系統(tǒng)在云平臺的部署提供了理論保證。 3、基于系統(tǒng)在業(yè)務、功能、性能及云平臺部署方面的考慮，文章在這些方面進行了需求分析和可行性分析。 4、文章提出一種動態(tài)優(yōu)先級傳輸調度模型，解決了對實時性要求高的重要信息不能及時傳輸的問題。同時，為實現系統(tǒng)支持海量請求的數據通信功能，，文章研究了基于完成端口（IOCP）的Socket通信機制。 基于以上的理論研究和需求分析，本文對第二代感知適配網關進行了詳細系統(tǒng)設計實現及云平臺的部署。經過系統(tǒng)的測試，第二代感知適配網關系統(tǒng)在可靠性、并發(fā)性等方面都達到了預期的設計要求。
[Abstract]:Intelligent agriculture is the result of the combination of modern computer technology, network communication technology and sensor technology. Users can control the remote crops intelligently by means of wireless communication network through the intelligent agricultural system platform. As an indispensable part of intelligent agricultural system, sensing adaptation gateway provides a way for relay and forwarding of sensor data. The second generation apperceiving gateway designed in this paper is based on the original upgrade of the system. The emphasis of the research is to optimize the performance of the priority transmission and concurrency of the system. A dynamic priority transmission scheduling model and Socket communication mechanism based on IOCP are proposed. The optimized perceptual adaptation gateway system can meet the needs of agricultural development in the future because of the large amount of concurrent data transmission. In addition, this paper upgrades the functionality of the apperceive adaptation gateway and researches its deployment on the cloud platform. The main research work is as follows: 1. On the basis of summarizing the research status and development background of intelligent agriculture at home and abroad, the necessity of developing a new generation of apperceive adaptation gateway and the technical difficulties involved are analyzed. 2. In this paper, the related core technologies involved in building the system are studied in depth. Firstly, the network communication technology is studied, and the Socket programming, Windows socket and synchronous asynchronous I / O are described in detail. It provides a solid theoretical foundation for the later system performance optimization. Secondly, the related technologies of cloud platform are studied, including the definition, characteristics, application and architecture of cloud platform, which provides a theoretical guarantee for the deployment of the later system in the cloud platform. 3. Based on the considerations of business, function, performance and cloud platform deployment, this paper analyzes the requirements and feasibility of the system. 4. In this paper, a dynamic priority transmission scheduling model is proposed, which solves the problem that important information with high real-time requirement can not be transmitted in time. At the same time, in order to realize the data communication function of mass requests, the Socket communication mechanism based on the completion port (IOCP) is studied in this paper. Based on the above theoretical research and requirement analysis, the second generation apperceiving gateway is designed and implemented in detail and the cloud platform is deployed. Through the system test, the second generation apperceive adaptation gateway system meets the expected design requirements in reliability, concurrency and so on.
