基于单片机的地铁站环境监测系统设计
摘要
地铁作为当今社会必不可少的交通工具,为人们的出行提供了很大的便利。当前的地铁环境存在检测不准确、不及时等缺陷,为了有效改善地铁的环境状况,设计一款只能地铁站环境监测系统势在必行。
本文基于STC89C52单片机设计一款地铁站环境监测系统。该系统通过相关传感器对地铁环境的相关参数进行实时监测,包括温度、CO2浓度、PM2.5浓度等,并将相关参数在LCD1602显示屏显示出来。当相关检测参数不在设置的范围内,相应的LED灯闪烁,且蜂鸣器报警。此外,本系统还外接蓝牙,可以将检测到的相关参数传输到手机上进行显示,还可以通过手机实现系统的远程控制功能。实物测试表明,该系统可以稳定运行,能够有效提高地铁站的环境管理水平。但在传感器选择、数据处理算法、显示界面设计等方面还有待改善。

Abstract
Abstract: As an essential means of transportation in today’s society, the subway provides great convenience for people’s travel. The current subway environment has defects such as inaccurate and untimely detection. In order to effectively improve the environmental conditions of the subway, it is imperative to design a subway station environmental monitoring system.
This article designs a subway station environmental monitoring system based on the STC89C52 microcontroller. The system monitors the relevant parameters of the subway environment in real-time through relevant sensors, including temperature, CO2 concentration, PM2.5 concentration, etc., and displays the relevant parameters on the LCD1602 display screen. When the relevant detection parameters are not within the set range, the corresponding LED light flashes and the buzzer alarms. In addition, this system is also connected to Bluetooth, which can transmit the detected relevant parameters to the mobile phone for display. It can also achieve remote control functions of the system through the mobile phone. Physical testing has shown that the system can operate stably and effectively improve the environmental management level of subway stations. However, there is still room for improvement in sensor selection, data processing algorithms, and display interface design.
