Development of an Embedded High-Temperature Field Measuring Instrument
This paper describes the development of an embedded high-temperature measuring instrument, which is composed of lens, photoelectric converter based on area-array CCD, and data acquisition, processing, Ethernet communication module based on DSP. The device is a creation of imaging spectrum, CCD imaging technology, digital image processing method and Ethernet communication together effectively. The advantages of this approach are: First, the networked measuring platform provides the possibility for process parameters optimization. Second, direct digital signal communication improves the anti-interference ability. Third, by employing 4-stage pipeline data processing mechanism greatly improves the real-time requirement. Fourth, through the constitution of application-layer protocol, the reliability of high-speed data transmission via Ethernet is guaranteed. The experiment by blackbody furnace in the laboratory shows that the maximum absolute error is 3.2 ℃, and the maximum relative error is 0.40％.
