7、电器中得到广泛应用。在实时检测和自动控制的单片机应用系统中单片机往往是作为一个核心部件来使用。水塔水位控制系统的基本要求是能够在无人监控的情况下自动进行工作，在水塔中的水位到达水位下限时自动启动电机，给水塔供水；在水塔水位达到水位上限的时候自动关闭电机，停止供水。并能在供水系统出现异常的时候能够发出警报，以及时排除故障，随时保证水塔的对外的正常供水作用。水塔是在日常生活和工业应用中经常见到的蓄水装置，通过对其水位的控制对外供水以满足需要，其水位控制具有普遍性。24不论社会经济如何飞速，水在人们正常生活和生产中起着重要的作用。一旦断了水，轻

8、则给人民生活带来极大的不便，重则可能造成严重的生产事故及损失，从而对供水系统提出了更高的要求，满足及时、准确、安全充足的供水。如果仍然使用人工方式，劳动强度大，工作效率低，安全性难以保障，由此
