摘要:
针对液化气监测系统具有实时性和突发性等特点,提出了一种应用在液化气监测中的动态预警方法,解决了在监控系统中需要手动调节阈值的问题。首先通过多传感器网络对被测环境中的数据进行采集,并利用贝塞尔公式对数据进行清理。采用加权数据融合算法对同类型传感器数据进行处理,根据二氧化碳浓度与爆炸上下限关系动态调整报警阈值。通过实地采集的数据计算,证明了该方法在不需要先验知识的情况下,可以有效减小系统误差,准确预警。
Abstract:
Considering the real-time and emergency of the liquefied gas monitor system,a dynamic warning method for the monitoring of the liquefied gas system is proposed here to solve the problem that people need to adjust the threshold by themselves.Firstly,the multi-sensor and the Bézier curve are used to collect and clean the data,then the weighted fusion is used to solve the data coming from the same type sensors and adjust the warning threshold based on the relationship between CO2 and the explosion limit of the liquefied gas.The calculating results prove that the method can reduce the error of the system and warn the problem without future knowledge.
