无线多路并行数据采集系统的设计

Design of Wireless Multi-Channel Parallel Data Acquisition System

本文针对工程实践的需要,设计了一种基于无线传输方式的多路信号并行采集系统RFDAQ-Ⅱ。RFDAQ-Ⅱ由一个数据接收单元和若干个并行数据采集单元组成,数据采集单元与接收单元之间通过无线的方式进行通讯,每个采集单元可进行最多四个通道的并行数据采集。本文介绍了RFDAQ-Ⅱ的系统原理和结构,并详细讲述了它的硬件结构、无线通讯协议及软件设计。

This paper designs a multi-channel parallel data acquisition system, RFDAQ-Ⅱ, which is based on wireless transmission. The RFDAQ-Ⅱsystem consists one data receiving unit and some data acquisition units. Each acquisition unit can sample four channels simultaneously at most. This paper introduces the principle and structure of the system, and discusses the hardware structure, wireless communication protocol and software design in detail.
