[摘要] 本文设计一个基于 TMS320LF2407EA 的多路无线温度采集系统,能够自动检测
DS18B20 个数,动态调整系统参数。主控 DSP 可以把温度数据显示在液晶屏幕中,并且
通过 nrf2401 无线模块传输到上位机,由 Qt 开发的程序将数据存储在 QSQLITE 数据库,
并用 Qwt 库绘制温度曲线。文章在简要介绍 DS18B20、nrf2401 无线模块、TMS320LF2407A、
液晶模块以及 Qt 开发工具和扩展库 Qwt 的基础上,详细介绍了无线温度采集系统的硬
件和软件设计的过程,以及在设计过程中要注意的问题。

Abstract: In this paper, a multi-channel wireless temperature acquisition system based on
TMS320LF2407EA is designed, which can automatically detect the number of DS18B20,
dynamically adjust parameters of system. Master DSP can displayed temperature data in the LCD
screen and transferred data to PC through wireless module nrf2401 .The program develop by the
Qt can stored the data in the QSQLITE database, and draw the temperature curve with Qwt library.
This paper briefly introduce DS18B20, nrf2401 wireless module, TMS320LF2407A, LCD module
and Qt development tools and extensions Qwt . Introduce the wireless temperature acquisition
system hardware and software design process and in the design process what issues should pay
attention.
Key words: DS18B20 Temperature Acquisition DSP Qt nRF2401
