基于无线传感器的矿井环境监测系统设计
摘 要
矿井作为资源开采的关键场所，工作环境极具挑战性。在矿井中，可能存在高温、高湿、高粉尘浓度、有害气体等多种危险因素，这些因素对矿工的健康和安全构成潜在威胁。因此，对矿井工作环境进行实时、准确的监测和控制是至关重要的。
本论文研究了基于无线传感器的矿井环境监测系统设计，采用STM32F103C8T6单片机作为控制核心。该系统具备多项重要功能，包括温度监测、粉尘浓度检测、声光报警、自动喷雾、参数设置、数据显示和远程控制等。在矿井工作环境中，温度和粉尘浓度的监测对工人的健康和安全至关重要。本系统的主要功能和特点如下：温度监测：通过DS18B20温度传感器实时测量矿井环境的温度。当温度超出预设的上下限范围时，系统会触发声光报警，及时提醒工人注意环境温度的变化。粉尘浓度检测：使用GP2Y10传感器测量粉尘浓度。当粉尘浓度超过设定的最大值时，系统将触发声光报警，同时自动启动喷雾装置，以减少粉尘浓度，保护工人免受有害粉尘的影响。参数设置：系统具有按键设置功能，工人可以通过按键轻松配置各种阈值，以满足不同环境条件下的监测需求。数据显示：采用OLED显示屏，实时显示测量的温度和粉尘浓度数据，让工人随时了解环境状况。蓝牙通信：系统与手机端通过蓝牙连接，允许手机端接收和保存数据，以及远程控制喷雾装置。这使得工人可以随时使用手机远程开关喷雾，提高了便捷性和安全性。
通过这一设计，矿井环境监测系统可以及时监测关键参数，提供警报和自动化应对措施，以确保工人在矿井工作时能够在安全和健康的环境中工作。此外，蓝牙通信功能还增强了数据的管理和远程控制的便捷性，为矿井管理和工人提供了更多的工具和手段。

Abstract
With the continuous advancement of technology and societal development, universities, as crucial institutions for knowledge dissemination and talent cultivation, are facing increasing challenges in terms of management and security. Among these challenges, the design and research of campus access control systems have become critically important to ensure the safety, convenience, and intelligence of university campuses. Traditional access control systems can no longer meet the demands of modern universities, thus necessitating more advanced and intelligent solutions. Additionally, with the ongoing emergence of fire and security issues, temperature monitoring and smoke detection have also become integral components of university access control systems.
This study aims to design and research an intelligent campus access control system based on RFID technology, with the STC89C52 microcontroller as the core control unit. This system encompasses several crucial functions, including RFID card-based access control, temperature monitoring, smoke detection, and the ability for users to set various thresholds through buttons. Firstly, the access control system supports two types of RFID cards: one pre-registered as valid and the other unregistered as invalid. When a valid card is swiped, the access control system opens the door, permitting entry to the cardholder. In the event of an invalid card swipe, the buzzer sounds an alarm for 2 seconds, and the access control remains locked, ensuring security.Secondly, the system integrates the DS18B20 temperature sensor for monitoring environmental temperature. If the temperature exceeds the preset maximum value (initially set at 60 degrees Celsius), the buzzer triggers an alarm and automatically opens the access control, mitigating potential fire or high-temperature situations. Additionally, the MQ-2 gas sensor, in conjunction with the ADC0832 module, is used to detect smoke concentrations in the environment. When the smoke concentration surpasses the set maximum value, the system triggers the buzzer alarm and automatically opens the access control, providing fire alarm and safety protection.To facilitate user configuration, the access control system offers buttons for users to customize various thresholds, including temperature and smoke maximum values. Finally, the CD1602 display screen is employed to show the status of card validity, current temperature readings, and smoke levels, enabling administrators and users to monitor the system’s status in real-time.
In conclusion, the university’s intelligent access control system based on the STC89C52 microcontroller, combined with RFID technology, temperature monitoring, and smoke detection, aims to provide enhanced campus entrance management and fire hazard warnings. Through a user-friendly configuration interface, the system allows administrators to easily adjust various parameters to meet different requirements and safety standards.
