给排水系统中水位检测技术的讨论给排水系统中水位检测技术的讨论 摘要:水位检测在许多控制领域已较为普遍,各种类型的给排水检测传感器较多,按原理分有浮子式、压力式、超声波式、吹气式等
但技术普遍落后或者操作复杂,本文利用圆形电容器原理,结合单片机设计出一种自动水位检测装置
关键词:给排水系统;电容器;单晶片;检测技术 Abstract: water level detection in many control field is a common, various types of water supply and drainage detection sensor is more, according to the principle of a float type, pressure points type, ultrasonic type, blowing type, etc
But the technology behind common or complex operation, this paper using circular capacitor theory, combined with the SCM design a kind of automatic water level detection device
Keywords: water supply and drainage system; Capacitor; Single crystal slices

前言 给排水系统中有许多需要检测水位的设施,如蓄水池、水塔、水源井、水库和水源河流等
这些设备一般采纳人工检测方式检测水位
随着自动化的进展,这些设备必须实现自动检测功能,这就需要适用的水位变送器
