摘要: 针对传统的瓦斯传感器校验仪校验点少、准确度不高、体积大的问题，设计了一种基于DSP的瓦斯传感器校验仪，详细介绍了该校验仪的软硬件设计。该校验仪以DSP芯片TMS320LF2407为主控芯片，实现了对8台瓦斯传感器的同时校验，且校验结果准确度高，大大提高了工作效率，节省了工作时间。Abstract: In allusion to problems of few calibration point, low accuracy and large volume of traditional calibrator for methane sensor, the paper proposed a design scheme of calibrator for methane sensor based on DSP and introduced hardware and software designs of the calibrator in details. The calibrator uses DSP chip TMS320LF2407 as main control chip, realizes simultaneous calibration of 8 methane sensors with accurate result, which greatly improves work efficiency and saves working time.
