基于MSP430和LabVIEW的无线低功耗多通道温度测试系统设计与实现

摘要

The paper designs a wireless temperature measurement system with long-distance and low-power and multi-channel based on the MSP430.The measuring system can measure and store 1000 points of temperature measurement on the object,calibrating data by encoding to ensure the reliability of data,and the sysmtem can implemente wireless transmis-sion by NRF24L01and transmit temperature data in real time over long distances by repeater named RS485,displaying and storing the current temperature values on the Labview-based PC.Node use MSP430F2011 as main chip,using DS18B20 as temperature acquisition sensor,which makes single 3V button battery-power.%设计制作了一种基于MSP430的无线长距离低功耗多通道温度测试系统。该测量系统能够测量和存储被测物体上1000个测量点的温度，对数据进行编码校验保证数据的可靠性，并且可以通过NRF24L01实现无线传输、通过RS485中继器实现长距离实时传输温度数据，最终在 PC 端基于 LabVIEW 的上位机上显示并存储当前温度值，节点采用MSP430F2011为主控芯片DS18B20为温度采集传感器，使用3V单节纽扣电池供电具有设置方便，适应性好，成本低廉，功耗低等优点。
