【摘要】:在能源危機的形勢下,太陽能作為新能源的代表,其關鍵技術已經有了極大的進步。而隨著移動互聯(lián)網與通信技術的快速發(fā)展,無線傳感器網絡(Wireless Sensor Network,WSN)的應用場合日益增多。因WSN具有容錯能力強、組織性好的特點,在環(huán)境監(jiān)測和信息采集等領域應用十分廣泛。受監(jiān)測和信息采集所處位置的影響,WSN分布條件的差異導致供電需求的不一,這就對各種復雜條件下信息采集系統(tǒng)的能源保障問題提出了更高的要求。因此,把太陽能應用到WSN領域,研究探討WSN的太陽能供電系統(tǒng)具有重大意義。本文首先簡單介紹了WSN的基本技術,然后就光伏電池的發(fā)電原理進行分析,建立相關的物理模型基本解析,并對光伏電池板MPPT(Maximum Power Point Tracking)算法中的電導增量法(Incremental Conductance algorithm,INCC algorithm)和干擾觀察法(Perturb and Observe algorithm,PO algorithm)進行了理論上的推導。以此為基礎,提出了一種自適應步長的INCC algorithm,從而直接關聯(lián)自適應步長與輸出電壓。對所建立的聯(lián)系進行了仿真測試,給出了相關測試數據。同時,本文針對特殊環(huán)境下WSN環(huán)境監(jiān)控系統(tǒng)的供電問題,進行了特殊環(huán)境下WSN太陽能供電系統(tǒng)的硬件電路設計,設計了一種魯棒性較強的太陽能的供電系統(tǒng)。該系統(tǒng)允許多路電源同時輸入為鋰電池充電,設計中采用外部USB電源和太陽能電池板為例共同為鋰電池進行充電。此外,還具備選擇控制存儲功能,根據優(yōu)先級原理,選擇性的為WSN節(jié)點供電;使用串口式NOR型閃存,存儲重要參數信息;針對山地等苛刻的環(huán)境,增設浪涌保護電路;利用圖形界面在PC機和移動終端進行顯示。最后,對本文中的研究內容進行了總結分析,查找了研究過程中遇到的盲點和不足,同時探討了在今后的研究工作中需要深入研究的問題。
[Abstract]:In the situation of energy crisis, solar energy as the representative of new energy, its key technology has made great progress. With the rapid development of mobile Internet and communication technology, the application of Wireless Sensor Network (WSN) is increasing day by day. WSN is widely used in environmental monitoring and information collection because of its strong fault tolerance and good organization. The different distribution conditions of WSN caused by the location of monitoring and information collection lead to different demand of power supply, which puts forward higher requirements for the energy security of information acquisition system under various complex conditions. Therefore, it is of great significance to apply solar energy to the field of WSN and study the solar power supply system of WSN. In this paper, the basic technology of WSN is introduced briefly, then the principle of photovoltaic cell generation is analyzed, and the related physical model is established. Theoretical derivation of incremental algorithm (InCC algorithm) and Perturb and observe algorithm (algorithm) in photovoltaic panel MPPT (maximum Power Point tracking) algorithm is also presented. Based on this, an adaptive step size algorithm is proposed to directly correlate the adaptive step size with the output voltage. The relation is simulated and the relevant test data are given. At the same time, aiming at the power supply of WSN environment monitoring system under special environment, this paper designs the hardware circuit of WSN solar power supply system under special environment, and designs a kind of solar power supply system with strong robustness. The system allows multiple power sources to be input to charge the lithium battery at the same time. In the design, the external USB power supply and solar panel are used to charge the lithium battery together. In addition, it also has the function of selective control and storage, according to the principle of priority, selectively supplying power to WSN node, using serial port nor flash memory to store important parameter information, adding surge protection circuit for harsh environment such as mountain area, etc. The graphical interface is used to display on PC and mobile terminal. Finally, the research contents in this paper are summarized and analyzed, the blind spots and deficiencies encountered in the research process are found, and the problems that need to be further studied in the future research work are also discussed.
