| Abstract: | A potable testing system for high-temperature with infrared laser spectral detection principle is introduced. Applied new thermometry which combined spectral absorption with high-temperature radiation in temperature testing, the infrared sensor for high-temperature detection is designed. The ARM hardware platform centralized on S3C44B0 is developed. It consists of A/D conversion module, LED display module and serial port communication module. Compared with the traditional sensors, the infrared sensor for high-temperature detection is characterized by rapid respond speed and high accuracy. With the ARM embedded processor, this system has advantages of good real-time performance, offline operation and portability. It has the broad application prospect . |
