基于单片机多功能水位控制系统

基于单片机多功能水位控制系统摘要随着人类社会的不断进步与发展，人类逐步进入了工业社会时代。在工业社会时代广袤的生产过程中，大多都有对特定罐体内液位高度控制的需求。但这些液位控制系统针对的控制对象大多是较为大型的控制对象，控制方式多为人力警戒与PLC大机组控制，缺乏灵活性与便利性。针对该问题，本文设计了一种基于小型微控制器的多功能罐体水位控制系统。该系统主要包括罐体液位传感器、微控制器、电控阀门、人机输入按钮、人机交互显示器几部分组成。该系统能根据设定的液位自动调用出液电磁阀与入液电磁阀，从而达到控制液位高度的目的。同时系统还具备显示系统，用户可根据显示系统远程观测罐内液位的高度：在要改变罐体液位设定时，本系统提供了用户交互按钮，用户可根据交互按钮重新设定液位高度，从而达到自由控制的目的。本文设计的多功能液位控制系统拟基于STC15W4K48S4微型控制器，该控制器从传统8051单片机改良而来，具有执行速度快、功耗低、片上外设丰富、外围电路简单的优点，满足本设计的需求场景。关键词：STC15W4K48S4微型控制器：电阻式液位传感器：自动控制AbstractWith the continuous progress and development of human society,human beings havegradually entered the era of industrial society.In the vast production process of the era ofindustrial society,most of them have the need for high level control in specific tanks.However,most of the control objects targeted by these liquid level control systems are relatively largecontrol objects,and the control methods are mostly manpower vigilance and PLC large unitcontrol,which lack flexibility and convenience.To solve this problem,a multifunctional tankwater level control system based on a small microcontroller is designed.The system mainlyincludes tank level sensor,microcontroller,electronic control valve,man-machine input button,human-computer interaction display.The system can automatically call the liquid outlet solenoidvalve and the liquid inlet solenoid valve according to the set liquid level,so as to achieve thepurpose of controlling the liquid level height.At the same time,the system also has a displaysystem,according to which the user can remotely observe the height of the liquid level in thetank;When changing the tank level setting,the system provides a user interaction button,and theuser can reset the level height according to the interactive button,so as to achieve the purpose offree control.The multi-functional liquid level control system designed in this paper is based onSTC15W4K48S4 microcontroller,which is improved from the traditional 8051 microcomputer,and has the advantages of fast execution speed,low power consumption,rich on-chip peripheralsand simple peripheral circuits,which meets the requirements of this design.Key Words:STC15W4K48S4 microcontroller,Resistive level sensor;Automatic control目录摘要Abstract..第一章引言…1.1研究意义1.2应用方向1.3微控核心1.4发展趋势.2第二章任务设计思路42.1液位控制逻辑..42.2系统控制过程.4第三章方案设计及论证，53.1理论验证.53.2系统总体设计….5第四章系统硬件设计…74.1人工控制部分….74.2自动控制部分.84.2.1显示屏部分.84.2.2微控制器部分.84.2.3液位控制部分.94.2.4液位传感器部分10第五章系统软件设计.12第六章系统测试.146.1默认工作状态测试..146.2出入液控制测试..146.3设置默认液位测试
