基于單片機檢測系統(tǒng)的設計
　　　　　
                         摘要
風速采集檢測系統(tǒng)隨著科技的進步已發(fā)展的日趨完善，但是目前風速檢測設備大都體積較大，質量大，因而造成十分不便攜，而且結構復雜，使用起來也極為繁瑣，制造成本也偏高。針對這一情況，本設計采用以AT89S51單片機為核心與風速傳感器連接起來構成集數(shù)據(jù)采集、處理、顯示、傳輸于一體的簡潔、便攜式風速檢測系統(tǒng)，此設計簡單易用，使用領域廣泛，有獨立電源系統(tǒng)，數(shù)據(jù)采集全面，分析準確，與如今很多風速采集檢測系統(tǒng)相有一定的創(chuàng)新意義。關鍵詞：單片機、簡潔、便攜式、風速采集、準確、易用。
Abrstract
Wind speed collection and detection system with the progress of science and technology has been the development of more and more perfect, but the wind speed detection devices are large volume, high quality, resulting in not very portable, and complicated in structure, the use is extremely cumbersome, the manufacturing cost is high. In view of this situation, this design uses the AT89S51 SCM as the core with the wind speed sensor is connected together to form a set of data acquisition, processing, display, transmission in one concise, portable wind speed detection system, the design is simple and easy to use, widely used in power system, independent, complete data acquisition, accurate analysis, and now a lot of wind speed collection and detection system which has the certain innovation significance
Keywords: single chip microcomputer, compact, portable, easy to use, accurate, wind speed collection.
