智能温湿度监测报警系统设计 摘要： 关键词： Intelligent temperature and humidity monitoring alarm system Abstract: Due to the temperture and the humidity is very important in the industrial and agricultural production . Such as canopy planting, granary management must ensure accurate temperature and humidity monitoring .This system according to the use of AT89S52 SCM performance and development situation of the comparatively detailed introduction, this system USES of the temperature and humidity sensor DHT11 do the performance of simple description. On the part of the circuit are introduced one by one, and finally realize the system hardware design, draw the circuit principle diagram. In the software design completed each function module flow chart, and according to the design requirements for function of the realization of the need after repeated simulation operation, debugging, modify, simplify, finally draw a complete set of software system. Topic main task is to complete two environmental temperature and humidity test, and can through the key set temperature and humidity on the floor, more than the lower limit, the system, such as LED light alarm. After the design of the system has good performance and easy to operate, and other advantages, realize the temperature and humidity of the display, alarm functions. Keywords: singlechip、Tenmperature and humidity、intelligent 目 录 前言 1 第1章 绪论 2 1.1 课题的意义和目的 2 1.2 课题的研究内容 2 1.3 课题的任务要求 2 第2章 系统方案设计 3 3 2.2 方案的选择与论证 4 2.2.1 方案的比较与论证 4 2.2.2 系统结构实现框图设计 5 第3章 系统各模块的硬件设计 6 6 3.2 温湿度测量模块设计 6 3.3 单片机控制模块设计 7 3.4 按键选择模块设计 8 3.5 显示模块设计 9 3.6 报警电路模块设计 9 3.7 时钟电路模块设计 10 3.8 复位模块设计 10 第4章 系统软件设计 11 11 4.2 主程序流程图设计 12 4.3 子程序流程图设计 12 4.3.1 按键电路设计 12 4.3.2 温湿度测量的软件设计 13 4.3.3 显示模块软件设计 14 4.3.4 报警软件设计 14 第5章 系统调试与数据分析 15 15 5.1.1 硬件电路的制作 15 5.1.2 硬件电路的调试 15 5.2 软硬件功能分析 16 5.2.1 软硬件的功能实现 16 5.2.2软硬件的不足及出现的问题 16 5.3 测试结果分析 17 第6章 总结 18 参考文献 19 致谢 20 附录1 电路原理图 21 附录2 程序 22 附录 元器件清单 33  多点温湿度的监测系统设计 前言 第1章 绪论 1.1 课题的意义和目的 1.2 课题的研究内容 1.3 课题的任务
