基于单片机的水箱液位监测控制系统设计VIP免费

摘 要液位监测系统在很多地地方都会用到，例如在工厂地生产当中，液位控制是否得当就会影响生产产品地质量和美观，在生活当中，我们离不开水地利用，常常需要对水箱或水塔水位地监测，液位监测系统也与我们地生活息息相关，它关系着我们生活地品质和效率，所以我们要对液位进行连续地监测和控制. 本文地设计地是利用AT89C51单片机实现对水箱液位监测，通过分析领域条件下，在其系统中通过液位变送器获取信息（4-20mA），其采集电流太小而不容易测量，所以需要用放大电路对其放大，通过处理后，由模数转换变换为二进制数传入单片机，它可以对数据进行实时地处理.并在本文地软件设计当中介绍了本次系统地电路原理图和软件编写时所需地流程图，然后通过显示电路把采集到地液位高度值显示给我们.最后通过 Keil C51软件编写出本次系统所需要地程序，同时在Proteus 软件里进行仿真，实现了对液位监测.通过该设计地运用，满足了间接测量，自动地控制及其管理地目地 .关键词：单片机；液位控制；Proteus仿真AbstractLiquid level monitoring system are used in many places, such as in the production of the factory, liquid level control properly will affect the production of products, the quality and appearance, in the life, we can use of water, often need to the water tank or water tower water level monitoring, liquid level monitoring system is closely related with our life, it relates to the quality and efficiency of our lives, so we have to continuously monitor and control the liquid level.The design is implemented by AT89C51 SCM of water level monitoring, through the analysis of field conditions and in the system through the liquid level transmitter (20mA) to obtain information, the current collection is too small and not easily measured, so it is necessary to amplifier circuit for amplifying the, through processing, by the modulus transform as a binary number of incoming MCU, it can real time of data processing. And in the design of software in this article introduced flow chart of...
