摘　　要：为提升宠物医院环境的舒适度与安全性,确保为宠物提供最佳的治疗与护理条件,设计并实现一种高效的宠物医院温湿度远程监控系统。采用DHT11温湿度传感器实时采集环境数据,以STC89C52RC单片机作为核心控制单元,负责数据的接收与处理;采集到的温湿度信息在LCD1602显示屏上直观展示,便于现场监控;利用AT24C02存储器存储预设的温湿度阈值,支持近端通过按键输入和远程通过短信输入两种灵活方式设置阈值。当监测到实际温湿度超出预设阈值时,系统立即触发声光报警机制,并通过GSM短信模块自动向宠物主人发送报警信息,提醒其注意,并可选择性地控制继电器设备,以自动调节环境温湿度至适宜范围。实验表明,系统响应迅速,监测数据准确,报警机制可靠,有效提升了宠物医院的环境管理水平和服务质量。所设计的宠物医院温湿度远程监控系统,以其高效、灵活、智能化的特点,为宠物医院提供了强有力的环境监控解决方案,确保了宠物治疗与护理过程的安全与舒适,具有较高的应用价值和推广前景。To improve the comfort and safety of the pet hospital environment and ensure the best treatment and care conditions for pets,an efficient remote temperature and humidity monitoring system for pet hospitals is designed and implemented.Real time environmental data is collected using DHT11 temperature and humidity sensors,with STC89C52RC microcontroller as the core control unit which is responsible for data reception and processing.The collected temperature and humidity information is visually displayed on the LCD1602 display screen,making it convenient for on-site monitoring.Utilizing AT24C02 memory to store preset temperature and humidity thresholds,it supports two flexible ways to set thresholds:near end input through buttons and remote input through SMS.When the actual temperature and humidity exceed the preset threshold,the system immediately triggers the sound and light alarm mechanism,and automatically sends an alarm message to the pet owner through the GSM SMS module to remind them to pay attention.It can also selectively control the relay device to automatically adjust the environmental temperature and humidity to the appropriate range.The experiment shows that the system responds quickly,the monitoring data is accurate,and the alarm mechanism is reliable,effectively improving the environmental management level and service quality of pet hospitals.The designed pet hospital temperature and humidity remote monitoring system,with its efficient,flexible,and intelligent characteristics,provides a powerful environmental monitoring solution for pet hospitals,ensuring the safety and comfort of pet treatment and care processes,and has high application value and promotion prospects.
