摘要:在線式UPS具有穩壓、穩頻、濾波、抗干擾等功能,廣泛地應用于國民生產的各個部門,對計算機系統尤為重要。本設計為一種基于8031 CPU 控制的在線式不間斷電源(UPS)。這里著重介紹了該UPS的工作原理及硬件與軟件設計。通過運用先進的電力電子技術和計算機控制技術,實現了該UPS的全數字、智能化控制。首先介紹了UPS電源的定義。UPS電源是隨著信息技術的不斷發展和計算機技術應用日益普及,高新技術產品對供電的質量要求越來越高。而普通交流電網供電時,所提供的電能不能滿足負載的嚴格要求,許多意外事故如浪涌、尖端干擾、噪音都可能發生。UPS在市電供電異常時,能向負載提供優質的電能。本論文系統的介紹了UPS電源的分類發展和現況,對將來的發展趨勢進行了預測。
關鍵詞:不間斷電源,在線式,8031單片機。
The research and design of the intelligence UPS power supply
Abstract: On-line UPS, with the function of stabilizing the voltage and the frequency , filtering and resisting the interaction , has been extensively used in every field of the national production, especially for the computer system. In this paper, design a on-line UPS based on 8031 CPU for computer technique was developed. The working principle and the design of hardware and software of the UPS was introduced. The full-digital/intelligent control of the UPS was realized by means of advanced electric/electronic technology and computer control technique. First introduces the definition of UPS. It is along with the development of Information and popularity of computer , equipment with high technology put forward more and more strict demand for quality of power supply. But at times, power a from wall socket is neither clean nor uninterruptible. Many abnormalities such as blackout, brownout, spikes, surges, and noise can occur. This is the function of an uninterruptible power supply(UPS) to act as a buffer and provide clean, reliable power to uninerable electronic equipment. The design Introduced the development classify and present conditions of UPS systematically.
Key words: power supply; UPS(Uninterruptible power supply); on line; 8031 microcontroller.
