基于无线传输的分布式数据处理实验教学平台设计

为了加强电子信息类专业知识的综合应用,综合多门专业课程实验教学需求,设计了基于无线传输的分布式数据处理实验教学平台。通过DS18B20采集多点温度数据将分布式温度数据输入到单片机无线发送模块,多点温度数据通过其配置的nRF24L01无线传输到单片机无线接收模块,并将接收到的多路温度数据通过RS232接口发送给计算机,利用VB实现温度数据的多路采集、实时动态显示、数据存储等功能。实验结果表明,该综合实验平台具有功能全面、操作简单、交互性强等优点,为学生实践能力与创新能力的培养提供了一个良好的实践平台。

In order to strengthen the comprehensive application of electronic information knowledge and meet the needs of many professional experimental educations, a distributed data-processing teaching platform for specialty experiments based on wireless transmission was designed. The DS18B20 collects multi-point temperature data and inputs the distributed temperature data into the wireless transmission module of the single-chip microcomputer. The multi-point temperature data is wirelessly transmitted to the wireless receiving module of the single-chip microcomputer through the configured nRF24L01, and the received multi-channel temperature data is sent to the computer through the RS232 interface. VB is used to realize multi-channel acquisition, real-time dynamic display and data storage of temperature data. The experimental results show that the comprehensive experimental platform has the advantages of comprehensive functions, simple operation and strong interactivity, which provides a good practice platform for the cultivation of students' practical ability and innovative ability.
