摘 要
本项目基于STC89C52单片机设计了一个智能车库控制系统，利用红外避障管、光电传感器、液位传感器和MQ-135气体传感器实现车位检测、指引、液位监测和有害气体检测等功能。系统通过LCD1602显示屏和按键进行参数设置和状态显示，通过声光报警和继电器控制实现安全和通风控制。车位检测：利用四个红外避障管检测四个车位（左右各两个）是否停车，每个车位配备一个红灯，停车时红灯亮起，指示车位已占用。车位指引：通过光电传感器检测车辆到来，通过8×8点阵显示屏显示箭头指引，指示可用车位的方向。优先指向右边的车位，当右边车位已满时，指引指向左边的车位，如果所有车位都满了，则显示“X”表示车库已满。液位监测：利用液位传感器检测车库液位，当液位超过设定的最大值时，系统触发声光报警，提醒用户车库液位过高，需要采取相应的措施。有害气体检测：通过MQ-135气体传感器检测车库内的有害气体浓度，当浓度超过设定的最大值时，系统触发声光报警，并通过控制继电器实现通风操作，确保车库内空气质量。参数设置：通过按键可设置各项阈值，如液位最大值、有害气体浓度最大值等，以适应不同需求和环境条件。状态显示：通过LCD1602显示屏实时显示车库液位、有害气体浓度以及剩余可用车位数，提供用户方便的状态监测。通过以上功能的设计和实现，基于STC89C52单片机的智能车库控制系统能够提供便捷的车位管理和车库环境监测，提高车库的利用率和安全性。未来的改进和扩展可以包括更多传感器的集成、监控和控制等功能，以进一步提升系统的性能和智能化水平，满足用户对智能车库的需求。

Abstract
This project presents the design of an intelligent garage control system based on the STC89C52 microcontroller. The system utilizes infrared obstacle sensors, photoelectric sensors, liquid level sensors, and MQ-135 gas sensors to achieve functions such as parking space detection, guidance, liquid level monitoring, and harmful gas detection. The system incorporates an LCD1602 display and buttons for parameter settings and status display, while ensuring safety and ventilation control through audio-visual alarms and relay control.The parking space detection feature employs four infrared obstacle sensors to detect the occupancy status of four parking spaces (two on each side). Each parking space is equipped with a red light that turns on when occupied, indicating its availability. The parking guidance feature utilizes photoelectric sensors to detect approaching vehicles and displays arrow directions on an 8×8 dot matrix display, guiding drivers to available parking spaces. Priority is given to the right-side parking spaces, and when they are full, the guidance points to the left-side spaces. If all spaces are occupied, the display shows an “X” to indicate a full garage.The liquid level monitoring function uses a liquid level sensor to detect the level in the garage. When the liquid level exceeds the predefined maximum value, the system triggers audio-visual alarms to alert users about the high liquid level and the need for appropriate actions. The harmful gas detection feature utilizes an MQ-135 gas sensor to monitor the concentration of harmful gases in the garage. If the concentration exceeds the set maximum value, the system triggers audio-visual alarms and controls a relay to initiate ventilation, ensuring good air quality inside the garage.Parameter settings can be adjusted using buttons, allowing users to customize threshold values such as maximum liquid level and harmful gas concentration according to their specific needs and environmental conditions. The LCD1602 display provides real-time information on the garage’s liquid level, harmful gas concentration, and the number of available parking spaces, enabling convenient status monitoring for users.By implementing the above functionalities, the intelligent garage control system based on the STC89C52 microcontroller offers convenient parking space management and garage environment monitoring, enhancing utilization and safety. Future improvements and expansions could involve integrating additional sensors, implementing monitoring and control capabilities, and further enhancing the system’s performance and level of intelligence to meet users’ demands for smart garages.
