摘要：沼氣能源是解決目前農村能源的最佳途徑。然而，目前沼氣發酵過程中存在諸多亟待解決的問題,其中反應器溫度的不穩定性一個重要問題。目前，國內大多采用常溫發酵工藝,該工藝方法很容易受到環境因素的制約,特別是在有些季節甚至會停止產氣。所以為沼氣池發酵提供一個理想的溫度環境是目前沼氣發酵中急需解決的問題。目前利用太陽能對反應器進行溫度控制的方法比較理想,然而該工藝也同樣受環境因素的制約,不能完全為發酵過程提供理想溫度環境。

　　　本課題從該問題點出發,設計基于單片機的溫控系統方案作為電能溫濕度控制的輔助裝置,實現反應器的理想溫濕度環境。該課題首先分析了該系統的設計要求和技術指標,確定系統的總體方案。然后考慮到經濟性能及體積因素,深入研究和選擇了各種芯片和元器件,該設計能夠實現溫度的實時檢測、顯示和控制輸出,使溫濕度值保持在理想的范圍內，并具有和上位機通訊,多點監測等功能。

ABSTRACT：Biogas energy is the best way to solve rural energy. However, the biogas fermentation process, there are many problems to be solved, the reactor temperature instability is the need to address an important factor. At present, most of the room temperature fermentation process, the process is constrained by environmental factors, in some seasons even stop the gas production. So provide an ideal temperature for methane fermentation environment is a the methane fermentation pressing problem. Ideal solar heating reactor, However, this process is also affected by environmental factors, and can not fully provide the desired temperature environment of the fermentation process. 

　　　This topic issue from the point of departure, the design temperature control system based on single chip solution temperature and humidity control as an auxiliary power unit, to achieve the ideal reactor temperature and humidity environments.The subject first analyzes the design of the system requirements and technical specifications, determine the system's overall program. Then consider the performance and size of the economic factors and selection of in-depth study of various chips and components designed to achieve the temperature of the real-time detection, display and control output, the temperature and humidity values ??in the desired range, and has the upper machine communication, multi-point monitoring and other functions.
