摘要
单片机由于其自身的特点，在生活中被运用的越来越广泛，不仅可以用在控制系统中，也可以用在数据采集系统中。温度和湿度是生活照中的基本的测量参数，如果能被准确的测量，将会对生产和研究有着重要的意义。本文设计选择STC89C52单片机作为核心控制岱片，LCD1602液晶屏为显示窗口，通过键盘完成系统的参数设定和控制，而且本系统还具有语音报警功能。本设计的硬件设计中，通过对系统的功能介绍选取了满足本设计要求的元器件，介绍了这些元器件的特点和模块电路的没计。软件设计部分通过流程图和时序图来表现了系统的软件设计方法，该部分主要分为两个过程：温湿度监测过程和温湿度控制过程，通过语音识别模块识别温度或湿度播报指令、播报当前温度或湿度。温湿度监测过程是通过传感器对温湿度进行预测，然后经过单片机，把结果发送到液晶屏上显示；本系统遵循了可靠性和性价比的设计原则，因此，在实际应中也可以取得良好的效果。通过以上功能实验，实现语音温湿度控制系统，可是给使用者实时提供当前环境的温湿度，且具有一定的使用价值。

Because of its own characteristics, the single chip microcomputer is used more and more widely in life, not only can be used in the control system, but also can be used in the data acquisition system. Temperature and humidity are the basic measurement parameters in daily photos. If they can be accurately measured, it will be of great significance to production and research. In this paper, STC89C52single chip microcomputer is selected as the core control chip, LCD1602 screen as the display window, through the keyboard to complete the parameter setting and control of the system, and the system also has voice alarm function. The hardware design of this design, through the function of the system selected to meet the requirements of the design components, introduced the characteristics of these components and module circuit. The software design part shows the software design method of the system through flow charts and time series diagrams. This part is mainly divided into two processes: temperature and humidity monitoring process and temperature and humidity control process. The voice recognition module recognizes the temperature or humidity broadcast instructions and broadcasts the current temperature or humidity. Temperature and humidity monitoring process is through the sensor to predict temperature and humidity, and then through the MCU, the results are sent to the LCD display; This system follows the design principle of reliability and cost performance, so it can also achieve good results in practice. Through the above functional experiments, the voice temperature and humidity control system is realized, but it provides the temperature and humidity of the current environment to the user in real time, and has certain use value.
