摘要:
针对智慧农业、工业仪表、航天航空等诸多应用领域中对多通道温度参数测量分析的实际需求,该文设计了一种基于STM32片内ADC(Analog-to-DigitalConverter, 模拟/数字转换器)采样多通道温度的测量系统,给出了恒流源激励与温度标定电路,热敏电阻PT100信号调理电路,多重ADC采样程序,TFT-LCD实时显示及Python数据统计分析。实验结果表明,该多通道测温系统最大测量误差为0.05℃,具有功耗低、性价比高、稳定性好等优势,能够有效满足相关应用领域中对多通道模拟信号进行量化分析的实际应用需求。
Abstract:
In view of the practical requirement of multi-channel temperature parameter measurement and analysis in many application fields such as smart agriculture, industrial instrumentation, aerospace, etc., this paper designs a multi-channel temperature measurement system based on the STM32 on-chip ADC (Analog-to-Digital Converter), which includes a constant current source excitation and temperature calibration circuit, a thermistor PT100 signal conditioning circuit, triple ADC sampling programs, TFT-LCD real-time display and Python data statistical analysis. The experimental results show that the maximum measurement error of the multi-channel temperature measurement system is 0.05 ℃, and it has the advantages of low power consumption, high cost performance, and good stability. It can effectively meet the practical application requirements for quantitative analysis of multi-channel analog signals in related application fields.
