基于单片机检测系统的设计
　　　　　
                         摘要
风速采集检测系统随着科技的进步已发展的日趋完善，但是目前风速检测设备大都体积较大，质量大，因而造成十分不便携，而且结构复杂，使用起来也极为繁琐，制造成本也偏高。针对这一情况，本设计采用以AT89S51单片机为核心与风速传感器连接起来构成集数据采集、处理、显示、传输于一体的简洁、便携式风速检测系统，此设计简单易用，使用领域广泛，有独立电源系统，数据采集全面，分析准确，与如今很多风速采集检测系统相有一定的创新意义。关键词：单片机、简洁、便携式、风速采集、准确、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.
