| 随着航空技术的发展，对热电偶的动态特性评价提出了更高的要求。针对现有热电偶采集方案不能连续采集以及无法实时获取温度值的问题，设计了一套基于LabVIEW的热电偶动态特性测试系统，并与示波器采集方案进行数据比对。经试验验证，该测试系统可靠性高，自动化程度高，有效地提高了工作效率，为温度传感器相关性能的评价提供了支撑。 |
| 英文摘要: |
| With the development of aviation technology, higher requirements are put forward for the dynamic characteristics of thermocouples. In view of the problem that the existing thermocouple acquisition scheme cannot continuously acquire and obtain the temperature value in real time, a set of thermocouple dynamic characteristics measurement system based on LabVIEW is designed. The working principle, hardware structure and software design of the system are described in detail, and the system is compared with the oscilloscope data collection scheme. The test results show that the system has high reliability and high automation, which effectively improves the working efficiency, and provides support for the performance evaluation of temperature sensors. |
