摘要
随着人们对生活和工作环境舒适度要求的提高，温度的精准控制变得愈发重要。传统的温度控制方式多依赖人工操作，不仅调节精度低、响应滞后，而且无法根据环境温度自动切换工作模式，难以满足现代生活和生产对温度控制的智能化需求。
基于 STC89C52 单片机的压缩机自动控制系统，整合了 DS18B20 温度检测模块、LCD1602 显示屏、按键、蓝牙模块、加热片、制冷片及风扇等，实现了环境温度的自动化监测与智能调控。系统核心功能包括：通过 DS18B20 实时检测环境温度，在自动模式下，当温度低于设置最小值时，控制加热片和风扇打开；当温度高于最大值时，自动启动制冷片和风扇。用户可通过手机选择制冷、制热、通风和自动模式，还能选择风扇的高、中、低三档风速，以及设置温度的最大值和最小值。为保护压缩机，系统设定在其停止工作后，需三分钟才能重启加热和制冷功能。同时，支持通过按键设置各阈值，通过 LCD1602 实时显示温度、工作模式、风扇挡位等数据。
该系统的实现，有效提升了温度控制的自动化与智能化水平，减少了人工操作，确保了环境温度的稳定，为生活和生产中的温度控制提供了高效、可靠的解决方案，同时为同类温度控制设备的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the increasing requirements for comfort in living and working environments, precise temperature control has become increasingly important. Traditional temperature control methods rely heavily on manual operation, which not only has low adjustment accuracy and delayed response but also cannot automatically switch working modes according to the ambient temperature, making it difficult to meet the intelligent needs of modern life and production for temperature control.
The STC89C52 single-chip microcomputer-based automatic compressor control system integrates the DS18B20 temperature detection module, LCD1602 display, buttons, Bluetooth module, heating plate, refrigeration plate, and fan, realizing automatic monitoring and intelligent regulation of ambient temperature. The core functions of the system include: real-time detection of ambient temperature through DS18B20. In automatic mode, when the temperature is lower than the set minimum value, the heating plate and fan are controlled to turn on; when the temperature is higher than the maximum value, the refrigeration plate and fan are automatically started. Users can select cooling, heating, ventilation, and automatic modes through their mobile phones, as well as choose high, medium, and low fan speeds, and set the maximum and minimum temperatures. To protect the compressor, the system is set to require three minutes to restart heating and cooling functions after it stops working. At the same time, it supports setting various thresholds through buttons, and real-time display of temperature, working mode, fan speed, and other data through LCD1602.
The implementation of this system has effectively improved the automation and intelligence level of temperature control, reduced manual operations, ensured the stability of ambient temperature, provided an efficient and reliable solution for temperature control in life and production, and also provided a reference for the research and development of similar temperature control equipment, with high practical application value.
