摘　　要：本文主要针对催化燃烧气体传感器在实际使用过程中经常出现的零点漂移现象提出的一种零点自动跟踪算法.该算法主要通过在预热状态下和监视状态下实时监测并采集零点数据,然后对采集到的零点数据进行计算处理最终实现实时跟踪,该算法可以解决因零点漂移引起的产品误报导致的产品质量问题.实践证明,该算法不影响仪表的安全使用,对复杂环境下的零点漂移问题也起到了较好的跟踪,提高了产品的可靠性.In this paper, a zero point automatic tracking algorithm is proposed to solve the problem of zero drift in the process of practical use of catalytic combustion gas sensor.The algorithm mainly monitors and collects zero point data in real-time under preheating state and monitoring state, then calculates and processes the collected zero point data, and finally realizes real-time tracking, The algorithm can solve the product quality problem caused by product false alarm caused by zero drift.Practice shows that the algorithm does not affect the safe use of the instrument, and it can track the zero drift problem in complex environment and improve the reliability of the product.
