摘要
无线通信以其不需铺设明线,使用便捷等特点,在现代通信领域占据重要地位。本文设计了一个基于nRF401无线传输模块的数据采集系统,它是利用无线传输将DS18B20测得的温度传送给PC进行处理的。同时,为了扩展串口的需要,还利用了模拟串口的思想,即把单片机的普通I/O口作为数据通信的模拟发送端和模拟接收端。本系统采用VB6.0来实现人机界面的设计,通过界面操作,可以实现对温度数据的实时显示和相关处理。实际运行后表明,该方法实现简单,功能适用,运行可靠。
The wireless communication has the important status in modern communication because it dose not need much line and its convenience. This paper designs a wireless transmission system based on the nRF401. It uses wireless transmission to deliver the temperature measured by DS18B20 to the PC machine. At the same time, we utilize the simulating serial port which uses the common I/O to send and receive the data. The system uses VB6.0 to carry out the design of the man-machine interface. It can carry out the manifestation of the temperature data and the related processing according to the interface operation. The practice proves that it is easy in implement, applicable in functions and reliable in operation.
