摘要
以铁路红外轴温探测系统为背景,采用高集成、高效率的TEC驱动芯片MAX1969、STM8L及外围电路构成红外光子探测器制冷电源,简化了电路设计,提高了制冷效率。在光子探头内部制冷模型创建中采用LabVIEW进行数据采集分析,在PID整定过程中采用Matlab/Simulink软件进行系统仿真。采用积分分离式PID算法,保证温度精确度达到±0.1℃,保障光子探测器探测率最优。
Based on the railway infrared temperature detection system, an infrared photon detector refrigeration power is constituted with high integration, high-efficiency TEC module driver MAX1969, STM8L MCU and oth- er peripheral circuit, which simplifies the design of circuit and increases the efficiency. In the modeling process of the detector, LabVIEW is used to collect and analyze the data. In setting parameters of PID, Matlab/Simu- link is used to simulate the system. PID algorithm of integral separation is adopted to ensure the precision of the temperature up to ±0.1℃ and guarantee the infrared photon detector to the best performance.
