【正文】 第 1 頁 共 17 頁課程設計(論文)說明書題 目: 水滿水缺音樂報警器 院 (系): 信息與通信學院 專 業(yè): 電子信息工程 學生姓名: 學 號: 指導教師: 職 稱: 2010年12月19日摘 要 本次設計的水滿水缺音樂報警器包括水位檢測,信號處理,報警輸出,和報警指示部分。系統(tǒng)通過水位檢測,根據(jù)相應的水電阻來導通或截止三極管,通過三極管的電位差來導通發(fā)光二極管LED和二極管D,使相應的報警燈亮,并觸發(fā)音樂芯片HS088,通過揚聲器發(fā)出報警音樂!設計要求能對過高或過低水位進行檢測,并做出相應的報警信號!系統(tǒng)主要由四部分組成:第一是水位檢測部分,第二是信號處理部分,第三是水位報警輸出和報警指示部分,第四是揚聲器發(fā)出報警音樂部分。關鍵詞:HS088;揚聲器;報警 AbstractThis design39。s water full water lacks music alarm apparatus including the water level examination, the signal processing, the warning output, and warning instruction part. According to the water level, the system uses the water and electricity to e the breakover or to cut off the triode, es breakover LED and D through triode39。s potential difference, is the corresponding warning light is bright, and triggers music chip HS088, sends out the warning music through the speaker! The design requirements can the low water level carry on the examination to Gao Huo, and makes the corresponding alarm! The system is mainly posed of four parts: First is the water level examination part, second is the signal processing part, third is the water level warning outputs and reports to the police the instruction part, fourth is the speaker sends out the warning music part.
