第三章 软件设计
人类社会发展的历史与能源的开发和利用水平密切相关，每一次新型能源的 开发都使人类经济的发展产生一次飞跃。在自然界中，风是一种可再生、无污染 而且储量巨大的能源。随着全球气候变暖和能源危机，各国都在加紧对风力的开 发和利用，尽量减少二氧化碳等温室气体的排放，保护我们赖以生存的地球。
本文介绍了用 AT89S52 系列单片机设计监测风速风向的数据采集处理系统 以及显示模块。对于风速该系统采用单片机技术。压力传感器采集的数据交给 单片机处理，再由液晶显示屏显示测量的风速值。对于风向该系统利用编码器 在 0-360。范围内进行测量收集信号，在多圈旋转的情况下能够实现单圈自动归 零，通过单片机进行格雷码转化处理，测量风向通过数码管显示。软件部分的设 计采用模块编程，方便今后的维护和改进。
