智能公共浴室系统的研究与设计

Research and Design of Intelligent Public Bathroom System

该设计将STC89C52单片机与公共浴室系统作为系统的设计核心,运用DHT11温湿度传感器对空气中的温度数据进行采集,并利用其内置A/D转换功能,将采集到的模拟信号转换成数字信号,再通过单片机对该数字信号进行分析与处理,将处理后的数据显示在LCD1602上,同时单片机也能够智能控制公共浴室系统的工作状态。该设计还拥有水位监测电路以及报警电路,防止水位过低而烧坏硬件。系统有电路简单,传感器的灵敏度高,采集的数据精度高,具有较高的安全性等优点。

This design takes STC89C52 Single-Chip Microcomputer and public bathroom system as the design cores of the system.It uses the temperature and humidity sensor DHT11 to collect the temperature data in the air,and uses its built-in A/D conversion function to convert the collected analog signal into digital signal.Then the digital signal is analyzed and processed by the Single-Chip Microcomputer,and the processed data is displayed on LCD1602.At the same time,the Single-Chip Microcomputer can intelligently control the working state of the public bathroom system.The design also has a water level monitoring circuit and an alarm circuit,which can prevent the low water level from burning out the hardware.The system has advantages of simple circuit,high sensitivity of the sensors,high accuracy of collection data,higher security and so on.
