【摘要】：太陽光的照射角度對光電池的效率具有顯著的影響,在太陽能聚焦系統(tǒng)中也對太陽光照射角度有嚴格的要求,因此設計能夠實現實時追蹤的太陽光追蹤系統(tǒng)具有非常重要的意義。現在主要流行的追蹤方式有視日運動軌跡追蹤和光電追蹤,追蹤機構多選用高度角-方位角雙軸追蹤裝置。光電追蹤具有定位精度高,追蹤靈活,價格較低的優(yōu)點。本文根據目前太陽光追蹤的現狀,設計了一種采用光電追蹤方式、基于高度角-方位角雙軸機械結構的追蹤系統(tǒng)。本系統(tǒng)控制器選用基于AR M內核的STM32F103控制器,利用光電傳感器、步進電機、追蹤機構實現對太陽光的追蹤。本文主要做了一下幾方面的工作:本文研究了太陽光追蹤的幾種方式及在高度角-方位角追蹤方式中太陽的定位問題。通過幾種追蹤方式的比較,結合理論知識和前人的研究成果,提出了新型三電池定位追蹤和模擬太陽光軌跡的追蹤方式,最終確定了系統(tǒng)的三電池定位的實現方案。同時,完成整個系統(tǒng)硬件電路部分和軟件編程部分,具體包括:1.硬件部分首先介紹了單片機、P CB電路板、光電池的原理等概念性知識,接著介紹了S TM32最小系統(tǒng)的組成和工作原理,最后重點介紹了本系統(tǒng)包括的幾個模塊:電壓采集模塊,電機控制模塊,上位機模塊。給出各個模塊的原理圖,并對每個模塊的工作原理和功能加以詳述。2.軟件部分首先介紹了系統(tǒng)軟件的運行環(huán)境,給出了系統(tǒng)軟件開發(fā)的流程圖,接著對系統(tǒng)軟件的組成模塊:系統(tǒng)的初始化,觸摸屏模塊,串口通信模塊,太陽光采集模塊,電機模塊等的設計思路加以詳述。本文最后介紹了系統(tǒng)調試的過程和有關結果,對實驗采集結果,運行情況進行研究,提出了精度測量的方法。驗證表明硬件和軟件調試都達到設計要求,系統(tǒng)追蹤效果良好。
[Abstract]:The solar irradiation angle has a significant effect on the efficiency of the photocell, and it has strict requirements in the solar focusing system. Therefore, it is of great significance to design a solar tracking system that can realize real-time tracking. At present, the main tracking methods are tracking the track of the sun motion and optoelectronic tracking, and the biaxial tracking device of height angle and azimuth angle is often used in the tracking mechanism. Photoelectric tracking has the advantages of high positioning accuracy, flexible tracking and low price. According to the current situation of solar tracing, a tracking system based on the biaxial mechanical structure of height angle and azimuth is designed in this paper. In this system, the STM32F103 controller based on AR M kernel is used to realize the tracking of solar light by using photoelectric sensor, step motor and tracking mechanism. In this paper, several aspects of work are mainly done: this paper studies several ways of solar tracing and the positioning of the sun in the way of altitude angle-azimuth tracing. Based on the comparison of several tracking methods, combined with theoretical knowledge and previous research results, a new type of three-cell positioning tracking and simulating solar track tracking method is proposed. Finally, the realization scheme of the three-cell positioning system is determined. At the same time, complete the whole system hardware circuit and software programming part, including: 1. The hardware part first introduces the concept knowledge of MCU PCB circuit board and photocell, then introduces the composition and working principle of S TM32 minimum system. Finally, the paper introduces several modules of this system: voltage acquisition module. Motor control module, upper computer module. The schematic diagram of each module is given, and the working principle and function of each module are described in detail. The software part first introduces the running environment of the system software, gives the flow chart of the system software development, and then the system software component modules: system initialization, touch screen module, serial communication module, solar light acquisition module. The design idea of motor module is described in detail. At the end of this paper, the process of system debugging and the related results are introduced. The experimental results and operation are studied, and the method of precision measurement is put forward. Verification shows that both hardware and software debugging meet the design requirements, and the system tracking effect is good.
