提出了一种基于MSP430单片机的便携式多路数据采集系统.系统分为数据采集和数据通信2部分,数据采集部分采集多路数据,数据通信部分与上位机建立串口通信,2部分之间则采用nRF24L01为核心器件的无线模块互传数据;数据于上位机上的实时显示界面由LabVIEW软件实现.给出了相关的硬件设计和软件设计方案,系统功耗低、成本低,操作简单,可便携佩戴,且具有很强的可扩展性,是一种可行的动态压力多路数据采集系统.
This paper presents a portable multi-channel data acquisition system based on MSP430 single-chip microcomputer.The system is divided into two parts: data acquisition and data communication, the data acquisition part to collect multiple data, the data communication part to establish serial communication with the host computer, nRF24L01 is the core module of the wireless module for each other data transmission; data on the host computer’s real-time display interface by the LabVIEW software.Considering the hardware design and software design, low power consumption, low cost, simple operation, portable wear , And has a strong scalability, is a viable dynamic pressure multiplexing data acquisition system.
