基于PLC水塔水位监测设计.doc

摘 要 随着社会的发展高楼逐渐变成了人们的居所，而高楼供水日渐成为人们日常生活中的一个问题，而水塔成为人们供水的首要选择。本文结合水塔的设计，供给水的需求，主要解决水塔的持续供水和水位、水压的检测。我们主要用传感器对其信号的收集，转换为相应的电信号。从而来控制抽水泵和加压水泵的工作来达到给居民楼于恒压不断水的供给。解决高楼的水压水量不足给人们日常生活带来不便的问题。 水位控制在日常生活及工业领域中应用相当广泛， 比如水塔、 地下水、 水电站等情况下的水位控制。 自动检测水位的检测系统能根据水位变化的 情况自动调节。本设计采用PLC进行主控制，利用传感器测量水位的变化，把测量到的水位变化转换成相应的电信号，用A/D转换器对接收到的信号进行数据处理，完成水位的检测、控制及故障报警。 该设计主要集合了PLC的应用、传感器的应用和数模转换的应用等；通过对学科知识的一个集合来构造此设计，从而来提高自己的构思能力，同时是对自己所学的知识的一个检阅；对所学科目的一个总体构思。 关键词：水位、传感器、PLC Abstract With the development of building society gradually into peoples homes and buildings, water supply is becoming a problem in peoples daily life, and becomes the first choice of the people of water tower. In this paper, combined with the tower design, the water supply demand, mainly to solve the continuous water supply and water level detection, the pressure of the water tower. We mainly used to collect sensor to the signal, is converted to a corresponding electrical signal. In order to control the water pump and the pressure pump to work to give residents in constant pressure water supply. To solve the problem of pressure water tower to peoples daily life inconvenient problem. Water level control is widely used in daily life and industrial fields, such as the water level of the water tower, water, hydropower station under the condition of control. Automatic detection system of water level can be automatically adjusted according to water level changes. This design uses PLC for the main control, sensor using the change water level measurement, the measured water level to change into a corresponding electrical signal by A/D converter, the received signal and data processing, the water level detection, control and fault alarm completed. The design of the main set of applications and data model application, sensor PLC conversion applications; through a set of subject knowledge to construct this design, so as to improve their thinking ability, also is a parade of his knowledge; to have an overall idea of the subject。
