1、沈阳理工大学学士学位论文I摘摘 要要在当今社会，水塔水位控制系统在我们的各个行业中占有很重大的作用，在大型养殖场中为家畜提供饮用水，冲洗养殖圈；在工业生产中通过水塔控制系统来排放污水。然而传统的水塔控制系统存在很大的不足，需要工作人员时刻监控，需要的劳动力十分强大，而且还会带来很多不足，轻则给人们的生活带来很大的不便，重则出现造成很大的事故和经济损失。本次设计采用基于单片机水塔水位控制系统，为了使实际供水过程中要确保水位在允许的范围内浮动，应采用电压控制水位。首先通过实时检测测量水位变化，从而控制电动机，保证水位正常。因此，这里给出以 STC 公司的STC89C52 单片机为核心器件的水塔水位
2、检测控制系统仿真设计，实现水位的检测控制、处理等功能，并在 Proteus 软件环境下实际仿真。系统程序语言是使用比较广泛的 C语言进行编写，结构清晰，达到的系统控制效果很好。实验结果表明，该系统具有良好的检测控制功能，可移植性和扩展性强。该基于单片机的水塔水位控制系统方便，降低工作人员的工作量提高了整体的效率。关键词关键词：水塔控制；单片机 STC89C52；Proteus 软件；C 语言沈阳理工大学学士学位论文IIAbstractIn todays society, the water tower water level control system plays very importan
