基于无线多点通信数据传输的温度与湿度检测系统详解.doc

摘 要 温度和湿度是两个最基本的环境参数，与人们的生活息息相关。在工农业生产、气象、环保、国防、科研等部门，经常需要对环境温度和湿度进行测量和控制。准确测量温湿度在生物制药、食品加工、造纸等行业更是至关重要。因此研究温湿度的测量和控制方法具有重要的意义。 一种基于无线多点通信数据传输的温度与湿度检测系统，采用模块化设计，有一套简单可靠的通信协议。系统设计实用简洁，实际应用中有很高的灵活性和可扩展性。此种模式还可以用于不同的系统。要防止仓储保存的物品变质，对仓库环境温度和湿度的控制显得极为重要。本系统采用单片机联合上位机对温度、湿度进行实时检测、数字显示和实时控制。关键词：温湿度传感器显示器；单片机；串通信Abstract Temperature and humidity are two basic environmental parameters which are closely related to people’s lives. In the industrial and agriculture production, meteorology, environmental protection, national defense, scientific research and other departments, we often need to measure and control the temperature and humidity of the environment. Accurate measurement of temperature and humidity in the pharmaceutical, food processing, paper making and other sectors is essential. So the method of temperature and humidity control and measurement is of great significance. One temperature and humidity detecting system based on wireless multi—point data transmission is introduced in this paper．The system applies modularization design and a set of easy and reliable communication protoco1．This design is convenient to useand easy to build．It has high flexibility and extendibility in practical application．Some pattern can be used in diferent system.Deterioration of items to prevent storage preservation of the warehouse environment temperature and humidity.The control is very important. This system adopts single-chip microcomputer combined PC for temperature.Degrees, humidity real-time detection, digital display, and real-time control. The design implementation of measurement and control temperature and humidity is MCU system, through which the temperature and humidity measurement LCD. System adopts set temperature and humidity sensor and A/D converter for SHT11 chip microcontroller processing, through that other modules including real-time display and alarm. The paper introduces the ATMEL company based on AT89C51 single-chip series of temperature and humidity measurement and
