【正文】 編號: 畢 業(yè) 設 計 題 目: 電阻、電容、電感測試儀 院 (系): 應用科技 學院 專 業(yè): 電子信息工程 題目類型: ?理論研究 ?實驗研究 ?工程設計 ?工程技術研究 ?軟件開發(fā) 桂林電子科技大學畢業(yè)設計(論文)報告用紙 摘 要 在使用電子元器件 時 ,首先 需要 了解參數 。 采用傳統(tǒng)的儀表進行測量時,首先要從電路板上焊開器件,再根據元件的類型,手動選擇量程擋位進行測量,這樣不僅麻煩而且破壞了電路板的 美觀 ?;趩纹瑱C控制實現的 RLC 測量儀可以在線測量、智能 識別 、量程自動轉換等多種功能,大大提高測量儀的測量速度和精度,擴大了測量范圍。因此這種 RLC 測量儀既可改善系統(tǒng)測量的性能,又保持了印刷電路的美觀,較傳統(tǒng)的測量儀還具有高度的智能儀和功能的集成化,在未來的應用中將具有廣闊的前景。 本課題主要研究內容為設計一個 基于單 片 機的 RLC 智能測量儀器,能夠智能地識別出待測元件是電容、電感還是電阻;能精確測量出電阻、電容、電感的參數值,同時還能加入語音播報的功能;可以實現量程電阻的自動轉換,無須人工選擇檔位;對測量儀進行擴充后還實現了二極管、三極管的 測量。 關鍵詞: RLC 測量儀 ; AT89S52; NE555 桂林電子科技大學畢業(yè)設計(論文)報告用紙 Abstract In the use of electronic ponents, the first need to understand parameters. Using the traditional instrument to measure, the first circuit board from a welding device, according to the type of ponents, manually select range Shift to measure, this is not only troublesome but also undermine The appearance of the circuit board. Based on SCM control to achieve the RLCmeasuring instrument can measure, intelligent identification, range automatic conversion, and other features, thereby greatly increasing the meter measuring speed and accuracy, expanded the range. So this RLC measuring instrument can improve the performance measurement system, and maintain the appearance of the printed circuit, the more traditional measuring instrument also is highly intelligent and functional instrument of integration and application in the future will have broad prospects. The main topics for the design of research has been based on the RLC SCM smart measuring instruments, smart and able to identify ponents under test is capacitors, inductors or resistance。 can be accurately measured resistors, capacitors, inductors of the parameters, while adding Voice of the broadcast function can be automatically converted range of the resistance, not artificial selection stalls。 measuring instrument to carry out the expanded also to achieve the diodes, transistors measurement.
