摘要
随着文化科普事业的蓬勃发展，植物展厅的智能化管理与良好展示效果对提升参观体验、保障植物生长具有重要意义。传统的展厅管理方式依赖人工巡查、手动操作，存在人流统计不精准、展示环境调控滞后、植物养护不及时等问题，难以满足现代化展厅的运营需求。
基于 STC89C52 单片机的多功能植物展厅系统，整合了分离式红外检测模块、5516 光照检测模块、FSR402 薄膜压力检测模块、YL69 土壤湿度检测模块、YS-17 火焰检测模块、CN-TTS 语音播报模块、按键、LCD1602 显示屏及执行设备（照明灯等），实现了植物展厅的智能化管理与展示服务。系统核心功能包括：通过分离式红外检测模块统计进入展厅的人数；借助 5516 光照检测模块监测光照强度，光照较低时自动打开照明灯；利用 FSR402 薄膜压力检测模块检测是否有人，检测到人时通过 CN-TTS 语音播报模块自动播报植物介绍；通过 YL69 土壤湿度检测模块监测土壤湿度，湿度较低时进行声光报警，并通过 CN-TTS 语音提醒工作人员灌溉；通过 YS-17 火焰检测模块检测是否发生火灾，检测到火焰时进行声光报警，同时语音提醒工作人员撤离；支持通过按键设置各参数阈值；通过 LCD1602 显示屏实时显示测量数据。
该系统的实现，有效提升了植物展厅的智能化管理水平，优化了参观体验，保障了植物生长与展厅安全，为植物展厅的高效运营提供了可靠解决方案，同时为同类展厅智能化系统的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the vigorous development of cultural and popular science undertakings, the intelligent management and good display effect of plant exhibition halls are of great significance for improving the visiting experience and ensuring the growth of plants. The traditional exhibition hall management method relies on manual inspection and manual operation, which has problems such as inaccurate passenger flow statistics, delayed regulation of the display environment, and untimely plant maintenance, making it difficult to meet the operational needs of modern exhibition halls.
The multifunctional plant exhibition hall system based on the STC89C52 single-chip microcomputer integrates a separate infrared detection module, 5516 light detection module, FSR402 film pressure detection module, YL69 soil moisture detection module, YS-17 flame detection module, CN-TTS voice broadcast module, buttons, LCD1602 display screen and executive equipment (such as lighting lamps), realizing the intelligent management and display service of the plant exhibition hall. The core functions of the system include: counting the number of people entering the exhibition hall through the separate infrared detection module; monitoring the light intensity with the help of the 5516 light detection module, and automatically turning on the lighting lamps when the light is low; using the FSR402 film pressure detection module to detect whether there is a person, and when a person is detected, the CN-TTS voice broadcast module will automatically broadcast the plant introduction; monitoring the soil moisture through the YL69 soil moisture detection module, and when the moisture is low, an acousto-optic alarm will be given, and the CN-TTS voice will remind the staff to irrigate; detecting whether a fire occurs through the YS-17 flame detection module, and when a flame is detected, an acousto-optic alarm will be given, and at the same time, a voice reminder will be given to the staff to evacuate; supporting the setting of various parameter thresholds through buttons; displaying the measured data in real time through the LCD1602 display screen.
The implementation of this system has effectively improved the intelligent management level of the plant exhibition hall, optimized the visiting experience, ensured the growth of plants and the safety of the exhibition hall, provided a reliable solution for the efficient operation of the plant exhibition hall, and also provided a reference for the research and development of similar intelligent exhibition hall systems, with high practical application value.
