    摘要:

    针对冶金、机械制造等工业生产中对温度测试的需求,设计了一种基于N型热电偶测温原理的高精度多通道的测温系统。该系统以STM32为控制核心,ADS1148作为采集芯片,并通过WiFi处理模块Esp8266实现数据的传送,使得用户可以远距离随时查看和监控数据。同时运用曲线拟合的最小二乘法对不同的传感器进行标定补偿,有效地提高了测温精度,避免了硬件调节的困难。实验结果表明,该系统的测温精度可以达到±0.1℃,且体积小、性能可靠,在工业生产具有良好的应用前景。

    Abstract:

    Aiming at the demand for temperature test in industrial production such as metallurgy and machinery manufacturing, a high-precision multi-channel temperature measurement system based on N-type thermocouple temperature measurement principle was designed. The system uses STM32 as the control core, ADS1148 as the acquisition chip, and the data transmission through the WiFi processing module Esp8266, so that users can view and monitor data at any distance. At the same time, the least square method of curve fitting is used to calibrate and compensate different sensors, which effectively improves the temperature measurement accuracy and avoids the difficulty of hardware adjustment. The experimental results show that the temperature measurement accuracy of the system can reach ±0.1 ℃, and the volume is small and the performance is reliable. It has a good application prospect in industrial production.
