多点无线温湿度采集实训系统的设计

Design of the temperature and humidity acquisition training system with multipoint wireless communication

项目驱动法是单片机实训中普遍使用的方法,开发综合实训项目对实验者提出了新的要求,从温湿度测量的实际需要出发,结合单片机实训设计了一个多点无线温湿度采集系统。由于温湿度空间分布不均,通常要求进行多点测量,用单片机作为核心控制器,结合数字式温湿度传感器和无线通信模块,在分散的地理空间建立传感器网络,实时采集温湿度信息。对系统原理进行了介绍,设计了硬件电路和软件流程。系统涉及单片机工程中常用的数据采集、无线通信、人机接口等内容,能较好地满足实训项目的要求,也可运用于多种场合的温湿度测量。

Project-driven is the widely used method at MCU practical training, from the needs of tem- perature-humidity measuring, a requirements puts forward to the experimenter for develop new com- prehensive training project. In this paper, a design of temperature and humidity acquisition training system with muhipoint wireless communication is distribution in the spaces, usually require a muhipoint ~ Because of temperature-humidity uneven measurement. A sensor network established in dispersed geographic space by digital temperature and humidity sensors and wireless communication module, MCU used as the main controller, temperature and humidity information can be collect in real -time. System principle introduced and also the hardware circuit and software flow designed. This sys- tem involving many content in MCU project, such as data collection, wireless communication, and man -machine interface. It can better meet the requirements of practical projects, can also be used in varie- ty of occasions of measurement of the temperature and humidity~
